SPL PL90 Equivalent & Substitute Parts

Part Overview

The SPL PL90 is a 905nm laser diode rated for 30W output power at 5.3V and 40A current, packaged in a radial configuration with 5mm diameter (T 1 3/4 form factor). This component is classified as Last Time Buy, indicating discontinued production with limited inventory availability. Identification of equivalent and substitute parts is necessary to ensure continued design support and procurement options for applications requiring 905nm laser diode functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPL PL90 laser diode is determined by the following critical parameters:

Wavelength Compatibility: All substitute parts must operate at 905nm to maintain optical system alignment and spectral matching requirements.

Radial Package Configuration: Substitute parts must utilize radial packaging to ensure mechanical compatibility with existing PCB layouts and thermal management designs.

Manufacturer Consistency: Parts sourced from ams-OSRAM USA INC. maintain design continuity and supply chain reliability.

Compliance Alignment: All substitute parts must maintain ROHS3 compliance and MSL 1 rating to satisfy regulatory and environmental requirements.

Electrical Parameter Variance: While wavelength and package type remain fixed, input voltage and current ratings may vary within the 905nm laser diode product family. Substitutes with different power outputs (75W versus 30W) and corresponding voltage/current specifications are acceptable when circuit design accommodates the electrical differences.

Engineering Selection Recommendations

SPL PL90AT03 Substitution Considerations:

The SPL PL90AT03 is an active product from ams-OSRAM USA INC. with ongoing production and supply availability, addressing the Last Time Buy status of the SPL PL90. Both parts maintain identical wavelength (905nm), radial package configuration, ROHS3 compliance, and MSL 1 rating.

The SPL PL90AT03 operates at higher power output (75W versus 30W) with corresponding changes in electrical specifications: 6V input voltage (versus 5.3V) and 25A current rating (versus 40A). Circuit designs must accommodate these electrical parameter differences through appropriate power supply adjustment and current limiting modifications.

The SPL PL90AT03 is supplied in Tape & Reel (TR) packaging format, whereas the SPL PL90 is available in Bulk packaging. Procurement and assembly processes may require adjustment to accommodate the different packaging format.

Frequently Asked Questions (FAQ)

Q: Can the SPL PL90AT03 directly replace the SPL PL90 without circuit modification?

A: No. While both parts share identical wavelength (905nm) and radial package configuration, the SPL PL90AT03 requires different input voltage (6V versus 5.3V) and operates at different current levels (25A versus 40A). Circuit power supply and current limiting components must be adjusted accordingly.

Q: Are there mechanical compatibility concerns between SPL PL90 and SPL PL90AT03?

A: Both parts utilize radial packaging. The SPL PL90 specifies 5mm diameter (T 1 3/4) form factor, while the SPL PL90AT03 specifies radial configuration. Mechanical compatibility depends on specific PCB footprint design and thermal management requirements of the application.

Q: What is the significance of the Last Time Buy status for the SPL PL90?

A: Last Time Buy indicates that the SPL PL90 is discontinued and no longer in production. Existing inventory is limited (5,000,300 pieces noted). The SPL PL90AT03, classified as Active, represents the current production alternative from ams-OSRAM USA INC. for 905nm laser diode applications.

Q: Do both parts meet the same regulatory and environmental standards?

A: Yes. Both the SPL PL90 and SPL PL90AT03 are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Q: What packaging format differences exist between these parts?

A: The SPL PL90 is supplied in Bulk packaging, while the SPL PL90AT03 is supplied in Tape & Reel (TR) format. Procurement, storage, and assembly processes may differ based on packaging format selection.

Q: Is the higher power output of the SPL PL90AT03 (75W) an advantage or disadvantage?

A: Power output suitability depends on application requirements. The 75W output of the SPL PL90AT03 provides higher optical power compared to the 30W SPL PL90. Applications requiring 30W output must implement appropriate optical attenuation or power limiting to prevent system damage or performance degradation.
