Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MMS-102-02-LM-SH is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 2 positions at 0.079" (2.00mm) mating pitch
• Mounting & Orientation: Surface mount, right-angle configuration
• Electrical Performance: 3.9A per contact current rating
• Environmental Specifications: Operating temperature range -55°C to 125°C
• Material & Finish: Gold-plated mating contacts, LCP insulation, phosphor bronze contact material
• Compliance: ROHS3 compliance and MSL 1 rating

The substitute part MMS-102-02-L-SH meets all these criteria and is therefore electrically and mechanically interchangeable with the main part number.

Frequently Asked Questions (FAQ)

Q: Are MMS-102-02-LM-SH and MMS-102-02-L-SH fully interchangeable?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical specifications across all critical parameters including connector type, position count, pitch, mounting configuration, current rating, operating temperature range, contact materials, and compliance certifications.

Q: What determines substitution eligibility for this connector series?

A: Substitution is valid when parts maintain identical values for connector type, number of positions, mating pitch, mounting type, contact configuration, current rating, operating temperature range, contact finish specifications, insulation material, and compliance status.

Q: Can these connectors be used interchangeably in existing designs?

A: Yes. The MMS-102-02-L-SH can directly replace the MMS-102-02-LM-SH in any application without design modification, as all electrical and mechanical parameters are identical.

Q: What is the significance of the part number suffix difference?

A: The suffix variation (LM vs. L) represents a manufacturing or packaging designation within the same product family. Both variants meet identical performance and compliance requirements.

Q: Are there any compliance or environmental differences between these parts?

A: No. Both parts carry ROHS3 compliance, EAR99 export classification, and MSL 1 rating. They are equivalent from regulatory and environmental perspectives.
