SPL TL90AT03 alternative: a qualified second source, not an emergency
Status: in full production · single-sourced · a 70 W 905 nm emitter worth dual-sourcing
The ams OSRAM SPL TL90AT03 is not discontinued. It is listed as Full Production on ams OSRAM's product page and is still sold. So this is not an end-of-life page — it is a supply-risk page. If a 65–70 W 905 nm emitter is on your production line — 3D sensing, CCTV surveillance, industrial automation — a single source is the risk; qualifying a second one is the fix.
The short answer
The functional second source for SPL TL90AT03 is PLD905-70W-M: a 70 W, 905 nm pulsed laser diode in the same Φ5.6 mm metal TO56 can. Both sit in the same can at 905 nm. The header, pinout and exact beam are confirmed against your drawing and on your bench before you commit — which is the part of a second-source qualification nobody should skip.
Status of the original part
SPL TL90AT03 is an active ams OSRAM part. The facts that matter for a second-source decision:
- Status: Full Production — not discontinued, not end-of-life. It is listed as Full Production on ams OSRAM's product page.
- Package: Metal CAN TO56 (Φ5.6 mm × 10 mm), RoHS.
- Rating: 65 W typical / 75 W max peak optical output (If = 20 A), 905 nm (898–912 nm), 9.5 V operating voltage (typ), −40 to +85 °C, 100 ns pulse / 0.1 % duty.
- ams OSRAM's pitch is a 3-emitter die with a 110 × 10 µm aperture, 7 nm spectral bandwidth and 35 K/W thermal resistance — and it is explicitly not released for automotive applications.
None of that argues for replacing it. What argues for qualifying a second source is that every one of those numbers comes from exactly one supplier.
The two parts, compared
All figures below are from the published datasheets: the ams OSRAM SPL TL90AT03 datasheet and the LumeLiDAR PLD905 datasheet.
| Parameter | SPL TL90AT03 (ams OSRAM) |
PLD905-70W-M (LumeLiDAR) |
|---|---|---|
| Peak power | 65 W typ (75 W max) | 70 W |
| Peak wavelength | 905 nm (898–912) | 905 nm ± 10 nm |
| Package | Metal CAN TO56 (Φ5.6 × 10 mm) | Φ5.6 mm metal TO56 can, 3-pin |
| Emitting area | 110 × 10 µm (3 emitters) | 90 × 18 µm |
| Beam divergence | 25° ⊥ / 10° // | 22° / 10° bare (FAC 6° / 10° via PLD905-70W-MCL) |
| Forward current | 20 A max | Per drive conditions — confirmed on samples |
| Match type | — | Functional; same can, pinout confirmed against your drawing |
| Supply status | Full Production | Active — samples from stock |
Beam divergence follows each manufacturer's datasheet convention; the axes are close but not identical (22° / 10° bare against 25° / 10°). A fast-axis-collimated build (PLD905-70W-MCL, 6° / 10°) is offered to close the gap against your receiver optics.

Your options, graded honestly
1. Stay single-sourced — if that is a conscious call
If your volumes are low, your lead times are comfortable, and a single supplier covers your product's life, there is no urgent reason to change. A second source is a project with a cost; only you know whether the risk justifies it.
What we will not do is dress this up as an emergency. It isn't one.
2. Qualify PLD905-70W-M as the second source
The same Φ5.6 TO56 can, 65–70 W at 905 nm. The qualification itself is the work: pinout and header confirmed against your drawing, then samples on your bench for spectrum, peak power and rise time.
That is the only part we do, and we do it before you order.
3. If you actually need more power in the same can
Some designs want the 100 W class rather than 70 W. If that is your part, the relevant page is the SPL UL90AT08 alternative — PLD905-100W-M carries the same can and qualification story one step up in power.
Same wavelength family, different wattage.
What "functional second source" does and does not mean
Functionally, the two parts are in the same can and the same power class. "Functional" — as opposed to "pin-to-pin" — is the honest grade when the mechanical interface needs a confirm against your drawing first. Specifically:
- The optical and thermal path matches: 905 nm, 70 W, Φ5.6 TO56
- The header, pinout and can height are confirmed against your mechanical drawing
- The beam is 22° / 10° bare, with a fast-axis-collimated build (PLD905-70W-MCL, 6° / 10°) available
Peak output under your drive conditions is confirmed per unit on your own test bench — the datasheet numbers match; the measurement that counts is yours.
How a second source gets qualified
- You send the part number — SPL TL90AT03 — with your annual quantity and drive conditions.
- We confirm the position in writing: functional match, what matches, what needs drawing verification.
- We ship two to five samples so you can measure spectrum, peak power and rise time on your own test bench.
- We quote production volume once your sign-off is in, and hold the agreed lead time.
Not sure which 905 nm configuration?
Peak power, package, beam divergence, drive conditions and temperature drift are the five decisions that pick the right 905 nm emitter. Our 905 nm selection guide walks through each one so you can narrow a 70 W part like PLD905-70W-M down to the exact build your receiver optics want.
Frequently asked
Is PLD905-70W-M pin-to-pin with SPL TL90AT03?
Functionally, with one mechanical caveat. Both parts sit in the same Φ5.6 mm metal TO56 can and deliver 65–70 W at 905 nm, so the optical and thermal path is close. What pin-to-pin does not settle is the exact header, pinout and can height — those are confirmed against your mechanical drawing before you order, not assumed. Optical output is then verified per unit on your own bench.
Why look for an alternative if SPL TL90AT03 is still produced?
Because it is single-sourced. SPL TL90AT03 is listed as Full Production by ams OSRAM, and it is not discontinued — so this is not an end-of-life story. The reason to qualify a second source is supply-risk diversification, price, and lead time, all of which matter once a 65–70 W 905 nm emitter sits on a volume production line such as 3D sensing, CCTV surveillance and industrial automation.
What is the difference in beam shape?
SPL TL90AT03 is specified at 25° (perpendicular) by 10° (parallel) over a 110 × 10 µm aperture. The PLD905-70W-M bare die is 22° by 10° over a 90 × 18 µm emitter, and the fast-axis-collimated PLD905-70W-MCL is 6° by 10°. The exact far-field match is confirmed on samples against your receiver optics, not on the datasheet headline.
Do you stock PLD905-70W-M?
We ship two to five samples from stock so you can measure spectrum, peak power and rise time on your own bench before any production commitment. Send the part number, your annual quantity and your drive conditions.
