PLT5 522EA_P Equivalent & Substitute Parts

Part Overview

The PLT5 522EA_P is a 520nm green laser diode manufactured by ams-OSRAM USA INC., rated at 20mW optical power with operating specifications of 6.3V input voltage and 68mA to 82mA current draw. The device is packaged in a TO-56-3 Lens Top Metal Can configuration and is classified as obsolete product status.

Due to its obsolete classification, sourcing the PLT5 522EA_P through standard distribution channels presents supply chain challenges. Identifying qualified substitute components with equivalent electrical and mechanical characteristics is necessary to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute qualification for the PLT5 522EA_P is determined by strict equivalence across the following critical parameters:

Wavelength: 520nm green laser diode specification must be maintained for optical system compatibility.

Optical Power: 20mW output power rating ensures functional equivalence in target applications.

Package Type: TO-56-3 Lens Top Metal Can configuration provides mechanical and thermal interface compatibility with existing PCB layouts and optical assemblies.

Electrical Operating Range: Input voltage and current specifications must fall within acceptable tolerance bands to ensure compatibility with existing power supply and drive circuitry.

Compliance Standards: RoHS3 compliance and MSL Level 1 rating must be maintained for regulatory and environmental requirements.

The PLT5 520EB_P meets all substitution criteria through equivalent wavelength, optical power, package configuration, and compliance certifications, with minor variations in input voltage (6.1V versus 6.3V) and current draw (78mA versus 68–82mA) that remain within acceptable operating margins for laser diode applications.

Parameter Comparison

Engineering Selection Recommendations

PLT5 520EB_P is the qualified substitute for PLT5 522EA_P based on the following engineering criteria:

Functional Equivalence: Both devices operate at 520nm wavelength with 20mW optical power output, ensuring direct functional replacement in optical systems designed for the original component.

Electrical Compatibility: The PLT5 520EB_P operates at 6.1V input with 78mA current draw, compared to the main part's 6.3V and 68–82mA specification. This 0.2V reduction and 78mA current value fall within the acceptable operating envelope for laser diode drive circuits designed for the PLT5 522EA_P.

Mechanical Compatibility: Identical TO-56-3 Lens Top Metal Can packaging ensures direct PCB footprint compatibility and optical assembly integration without design modification.

Regulatory Compliance: Both components maintain ROHS3 compliance and MSL Level 1 rating, satisfying environmental and moisture handling requirements.

Supply Status: The PLT5 520EB_P carries Active product status with 1295 units in stock, providing immediate availability compared to the obsolete PLT5 522EA_P.

Frequently Asked Questions (FAQ)

Q: Can the PLT5 520EB_P be used as a direct replacement for PLT5 522EA_P in existing designs?

A: Yes. The PLT5 520EB_P provides direct functional and mechanical replacement. Both devices share identical wavelength (520nm), optical power (20mW), and package configuration (TO-56-3 Lens Top Metal Can). Electrical parameters (6.1V input, 78mA current) are compatible with drive circuits designed for the original 6.3V, 68–82mA specification.

Q: What is the voltage difference between these two laser diodes?

A: The PLT5 522EA_P operates at 6.3V nominal input, while the PLT5 520EB_P operates at 6.1V. This 0.2V difference is within typical laser diode operating tolerance and does not require circuit redesign for standard power supply implementations.

Q: Are the package dimensions identical?

A: Yes. Both the PLT5 522EA_P and PLT5 520EB_P use the TO-56-3 Lens Top Metal Can package, ensuring identical mechanical footprint, thermal interface, and optical alignment characteristics.

Q: What compliance certifications apply to the substitute part?

A: The PLT5 520EB_P is ROHS3 compliant and carries MSL Level 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the original PLT5 522EA_P.

Q: Why is the PLT5 522EA_P listed as obsolete?

A: The PLT5 522EA_P is classified as obsolete by the manufacturer. The PLT5 520EB_P represents the active product line continuation with equivalent specifications and improved supply availability.

Q: Is there any difference in optical performance between these devices?

A: No. Both devices are specified at 520nm wavelength and 20mW optical power output. Optical performance characteristics are equivalent for applications requiring green laser diode functionality at this wavelength and power level.
