SL402M Equivalent & Substitute Parts

Part Overview

The SL402M is a 2-position circular connector plug with male pins and solder cup termination, manufactured by Switchcraft Inc. as part of the Slim-Line® SL40 series. This connector is designed for audio, industrial, marine, and medical applications requiring shielded connections with a 5A current rating. The SL402M is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance.

Substitute Part Grouping Explanation

The SL402MX qualifies as a direct substitute for the SL402M based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

• Connector type: Plug, Male Pins
• Number of positions: 2
• Shell size - insert: SL-2M
• Termination method: Solder Cup
• Fastening type: Threaded
• Shell material: Copper Alloy
• Shell finish: Nickel
• Contact finish - mating: Silver
• Current rating: 5A
• Cable opening: 0.280" (7.10mm)
• Shielding: Shielded
• Features: Cable Clamp, Coupling Nut, Strain Relief
• Material flammability rating: UL94 V-0

The SL402MX maintains full compatibility with the SL402M across all specified electrical and mechanical parameters, with the primary distinction being product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The SL402MX is the direct equivalent for the obsolete SL402M. Selection of the SL402MX is appropriate for new designs and replacement applications due to its active product status and ROHS3 compliance. The SL402M, classified as obsolete, is no longer recommended for new procurement. Both parts maintain identical electrical and mechanical specifications, ensuring functional interchangeability in Slim-Line® SL40 series applications.

The transition from SL402M to SL402MX aligns with current regulatory requirements while preserving all connector performance characteristics required for audio, industrial, marine, and medical applications.

Frequently Asked Questions (FAQ)

Q: Can the SL402MX directly replace the SL402M in existing assemblies?

A: Yes. The SL402MX maintains identical electrical and mechanical parameters, including connector type, pin configuration, shell size, termination method, current rating, and shielding characteristics. Direct substitution is valid for all applications.

Q: What is the primary difference between SL402M and SL402MX?

A: The SL402M is obsolete, while the SL402MX is active. Additionally, the SL402MX is ROHS3 compliant, whereas the SL402M is RoHS non-compliant. All functional specifications remain identical.

Q: Are there packaging differences between these parts?

A: The SL402MX is supplied in bulk packaging. The SL402M packaging specification is not provided in the technical data.

Q: What applications are supported by the SL402MX?

A: The SL402MX is suitable for audio, industrial, marine, and medical applications requiring 2-position shielded circular connectors with solder cup termination and 5A current capacity.

Q: Is the SL402MX compatible with existing SL40 series connector systems?

A: Yes. The SL402MX is part of the Slim-Line® SL40 series and maintains full compatibility with other components in this series.
