SPL PL90_3 Equivalent & Substitute Parts

Part Overview

The SPL PL90_3 is a 905nm laser diode manufactured by ams-OSRAM USA INC., rated for 90W output power at 40A operating current and 8–11V input voltage. The device is housed in a radial can package (5.7mm) and is designated as Last Time Buy status, indicating discontinued production with limited inventory availability. Identification of equivalent and substitute parts is necessary to ensure continued component availability for system integration and maintenance applications where this laser diode specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPL PL90_3 laser diode is determined by the following critical parameters:

Wavelength Matching: The substitute part must operate at 905nm to maintain optical system compatibility and performance characteristics.

Package Compatibility: Both the main part and substitute must use radial can package configurations to ensure mechanical fit within existing mounting and thermal management infrastructure.

Compliance Certification: All substitute parts must maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1) to satisfy regulatory and environmental requirements.

Base Product Series: Both parts share the SPL PL90 base product number, confirming they belong to the same laser diode family and design lineage.

The SPL PL90AT03 is identified as the manufacturer-recommended substitute. While this part operates at reduced power output (75W versus 90W) and lower current rating (25A versus 40A) at a different input voltage (6V versus 8–11V), it maintains the same wavelength, package type, and compliance certifications necessary for functional substitution in applications where the lower power specification is acceptable.

Parameter Comparison

Engineering Selection Recommendations

For SPL PL90_3 Substitution:

The SPL PL90AT03 is the manufacturer-designated substitute and is currently in active production status, providing assured long-term availability compared to the Last Time Buy status of the SPL PL90_3. Both parts maintain identical wavelength specification (905nm) and equivalent compliance certifications (ROHS3, EAR99 classification, unlimited MSL).

Selection of the SPL PL90AT03 requires system-level evaluation of power and current requirements. The substitute operates at 75W output power and 25A current versus the main part's 90W and 40A specifications. Applications requiring the full 90W output power cannot use this substitute without performance degradation. Applications designed for lower power operation or those with adjustable power settings may accommodate this substitute without functional impact.

The input voltage difference (6V for substitute versus 8–11V for main part) necessitates verification of power supply compatibility within the end-use system. The substitute's fixed 6V requirement differs from the main part's voltage range specification.

Both parts share ROHS3 compliance and unlimited moisture sensitivity classification, eliminating regulatory or environmental handling concerns during substitution.

Frequently Asked Questions (FAQ)

Q: Can the SPL PL90AT03 directly replace the SPL PL90_3 in all applications?

A: Direct replacement is limited to applications where 75W output power is acceptable. The SPL PL90AT03 operates at 15W lower power output and 15A lower current than the SPL PL90_3. Applications requiring the full 90W specification cannot use this substitute.

Q: Are there mechanical compatibility concerns between these parts?

A: Both parts use radial can package configurations. The SPL PL90_3 specifies 5.7mm can diameter, while the SPL PL90AT03 specifies radial package without dimensional detail in the provided data. Mechanical fit verification is required before integration.

Q: What is the voltage requirement difference between these parts?

A: The SPL PL90_3 operates across an 8–11V input range, providing design flexibility. The SPL PL90AT03 requires a fixed 6V input. Power supply redesign may be necessary if substituting into systems designed for the 8–11V range.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the SPL PL90_3 and SPL PL90AT03 are ROHS3 compliant, classified as EAR99 for export control purposes, and carry unlimited moisture sensitivity level (MSL 1) ratings.

Q: Why is the SPL PL90_3 marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued production of this part. The SPL PL90AT03, currently in active production status, is the recommended path for future procurement to ensure supply chain continuity.

Q: Are there other substitutes available for the SPL PL90_3?

A: Based on the provided data, the SPL PL90AT03 is the manufacturer-recommended substitute. No additional equivalent parts are specified in the reference materials.
