Key Parameters

Substitute Part Grouping Explanation

Substitution of the PLED5Q12 is based on the following critical parameters:

• Technology: LED Shunt protection devices only
• Series: PLED® family components
• Number of Circuits: Single circuit configuration
• Mounting Type: Surface mount technology
• Applications: LED protection functionality
• Compliance: ROHS3 compliance maintained

The PLED6N qualifies as a substitute based on matching technology, series, circuit count, mounting type, and application requirements. Both components are manufactured by Littelfuse and serve identical LED protection functions within the PLED® product line.

Parameter Comparison

Engineering Selection Recommendations

The PLED6N is the manufacturer-recommended substitute for the obsolete PLED5Q12. Both components maintain ROHS3 compliance and serve identical LED protection applications within the PLED® series. The PLED6N is currently in active production status, ensuring long-term availability and supply chain continuity. The primary design consideration is the package change from 2-VDFN to SOD-123F, which requires PCB layout modification. The PLED6N offers improved moisture sensitivity rating (MSL 1 versus MSL 3), providing enhanced reliability in humid environments.

Frequently Asked Questions (FAQ)

Q: Can PLED6N directly replace PLED5Q12 without design changes?

A: The PLED6N is functionally equivalent for LED protection applications but requires PCB layout modification due to package change from 2-VDFN to SOD-123F. Electrical performance remains compatible.

Q: What is the primary reason for substitution?

A: The PLED5Q12 is obsolete. The PLED6N is the active equivalent within the PLED® series, ensuring continued component availability.

Q: Are there compliance differences between these parts?

A: Both components are ROHS3 compliant. The PLED6N provides superior moisture sensitivity performance (MSL 1 versus MSL 3).

Q: What package considerations apply to this substitution?

A: The PLED5Q12 uses 2-VDFN packaging while PLED6N uses SOD-123F. PCB footprint and assembly process adjustments are required.

Q: Is the PLED6N suitable for the same LED protection applications?

A: Yes. Both components are designed for LED protection within the PLED® series and maintain identical application compatibility.
