PL 520_B1 Equivalent & Substitute Parts

Part Overview

The PL 520_B1 is a laser diode manufactured by ams-OSRAM USA INC. operating at 520nm wavelength with 50mW output power. This component is designed for applications requiring green laser emission in a radial, can-style 3-lead package. The PL 520_B1 is classified as obsolete, making identification of suitable substitute components necessary for ongoing system support and new design implementations. Substitute parts must maintain functional equivalence across wavelength, power output, and package configuration while accommodating operational parameter variations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PL 520_B1 laser diode is determined by the following critical parameters:

Primary Equivalence Criteria:

• Wavelength: 520nm (green laser emission)
• Power Output: 50mW (optical power specification)
• Package Configuration: Radial, Can - 3 Lead (mechanical and electrical interface)

Secondary Compatibility Factors:

• Voltage - Input: Operating voltage range tolerance
• Current Rating: Forward current specification
• RoHS Compliance: ROHS3 Compliant status
• Moisture Sensitivity Level: MSL 1 (Unlimited)

The PLT3 520FB substitute part maintains identical wavelength, power output, and package configuration. Operational parameters (voltage and current) differ within acceptable ranges for laser diode applications, reflecting design improvements in the active product line.

Engineering Selection Recommendations

PLT3 520FB as Primary Substitute:

The PLT3 520FB is the manufacturer-recommended substitute for the obsolete PL 520_B1. Both components share identical wavelength (520nm) and power output (50mW) specifications, ensuring optical performance equivalence. The package configuration (Radial, Can - 3 Lead) is identical, providing direct mechanical and electrical interface compatibility.

The PLT3 520FB operates at reduced voltage (6.5V versus 8V) and current (130mA versus 160mA), representing improved efficiency in the active product generation. Both components maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings, satisfying regulatory and environmental requirements.

The PLT3 520FB holds active product status with established supply availability (1105 pieces in stock), providing long-term sourcing stability compared to the obsolete PL 520_B1.

Frequently Asked Questions (FAQ)

Q: Can the PLT3 520FB directly replace the PL 520_B1 in existing applications?

A: Yes. Both components share identical wavelength (520nm), power output (50mW), and package configuration (Radial, Can - 3 Lead). The PLT3 520FB operates at lower voltage and current specifications, which represents improved performance characteristics in the active product line.

Q: What are the key differences between the PL 520_B1 and PLT3 520FB?

A: The primary differences are operational parameters and product status. The PLT3 520FB operates at 6.5V and 130mA compared to the PL 520_B1 at 8V and 160mA. The PLT3 520FB is an active product, while the PL 520_B1 is obsolete. Optical specifications (wavelength and power) remain identical.

Q: Are both components packaged identically?

A: Yes. Both the PL 520_B1 and PLT3 520FB use Radial, Can - 3 Lead package configuration, ensuring mechanical and electrical interface compatibility.

Q: Do both components meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings. Both are classified as REACH Unaffected and carry ECCN EAR99 designation.

Q: Why is the PLT3 520FB recommended over the PL 520_B1?

A: The PLT3 520FB is the manufacturer-recommended substitute and maintains active product status with established supply availability. The PL 520_B1 is obsolete, making the PLT3 520FB the appropriate choice for new designs and ongoing system support.

Q: What is the packaging difference between the two parts?

A: The PL 520_B1 is supplied in standard packaging, while the PLT3 520FB is supplied in Tray packaging. Both maintain identical component specifications and package case configuration.
