PLED6M Equivalent & Substitute Parts Reference

Part Overview

The PLED6M is a lighting protection LED shunt device manufactured by Littelfuse Inc., designed for surface mount applications with a 5.5V rating. This component is used in LED protection circuits to provide transient voltage suppression and circuit protection in lighting applications.

The PLED6M has been discontinued at DiGi Electronics. Identifying equivalent substitute parts ensures design continuity and maintains circuit performance in applications requiring LED shunt protection functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PLED6M is based on the following critical parameters that must align for functional equivalence:

• Technology: LED Shunt protection device
• Number of Circuits: Single circuit configuration
• Mounting Type: Surface mount capability
• Series Compatibility: PLED® series from Littelfuse
• RoHS Compliance: ROHS3 Compliant status
• Moisture Sensitivity: MSL 1 rating
• Applications: LED protection functionality

The PLED6N qualifies as a substitute based on matching technology, circuit count, mounting type, series designation, and compliance certifications. Package differences (DO-216AA versus SOD-123F) reflect different form factors within the same functional category and do not prevent substitution when PCB layout accommodates the alternative package.

Parameter Comparison

Engineering Selection Recommendations

The PLED6N is the manufacturer-recommended substitute for the discontinued PLED6M. Both components maintain identical ROHS3 compliance and MSL 1 ratings, ensuring compatibility with standard manufacturing and storage requirements.

The PLED6N is currently in active production status with available inventory, providing supply chain continuity for new designs and production runs. The package transition from DO-216AA to SOD-123F requires PCB layout modification but does not affect electrical performance in LED protection applications.

Selection of the PLED6N is supported by Littelfuse's official substitution designation and matching functional specifications across all critical parameters.

Frequently Asked Questions (FAQ)

Q: Can the PLED6N directly replace the PLED6M without circuit modification?

A: The PLED6N provides electrical equivalence as a single-circuit LED shunt protection device. PCB layout must be updated to accommodate the SOD-123F package footprint in place of the DO-216AA package.

Q: Are there compliance differences between PLED6M and PLED6N?

A: Both components maintain ROHS3 compliance and MSL 1 ratings. No compliance degradation occurs with substitution.

Q: What is the primary reason for substituting the PLED6M?

A: The PLED6M is discontinued at DiGi Electronics. The PLED6N is the active equivalent from the same manufacturer and series, ensuring continued availability and support.

Q: Does package change affect the protection characteristics?

A: Package form factor does not alter the LED shunt protection function. Both DO-216AA and SOD-123F packages are surface mount configurations suitable for LED protection applications.

Q: Is the PLED6N available in the same packaging format?

A: The PLED6N is supplied in Tape & Reel (TR) format, standard for surface mount production environments. The DO-216AA package of the PLED6M differs from the SOD-123F package of the PLED6N, requiring footprint adjustment during PCB redesign.
