Substitute Part Grouping Explanation

Substitute parts for the MMS-109-02-LM-SH are identified based on strict equivalence across the following critical parameters:

• Connector Type & Position Count: Receptacle, 9-position configuration
• Pitch Specification: 0.079" (2.00mm) mating pitch
• Mounting Configuration: Surface mount, right-angle orientation
• Contact System: Female socket, gold-plated mating surface
• Electrical Rating: 3.9A per contact capacity
• Temperature Range: -55°C to 125°C operating envelope
• Material Composition: Liquid Crystal Polymer insulation with phosphor bronze contacts
• Compliance: ROHS3 compliant status
• Series Family: MMS series base product number

The substitute part MMS-109-02-L-SH maintains identical electrical and mechanical specifications across all critical parameters, differing only in internal design designation while preserving full functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the MMS-109-02-LM-SH and MMS-109-02-L-SH are active products with ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability, as the MMS-109-02-L-SH currently maintains higher stock levels (1049 pcs vs. 791 pcs). Both parts carry MSL Level 1 (Unlimited) moisture sensitivity classification and are subject to identical export control designations (EAR99). No technical differentiation exists between these connectors for standard applications within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Are MMS-109-02-LM-SH and MMS-109-02-L-SH fully interchangeable?

A: Yes. Both connectors share identical electrical ratings (3.9A per contact), mechanical dimensions (9-position, 0.079" pitch, surface mount right-angle), contact materials (phosphor bronze with gold plating), and operating temperature range (-55°C to 125°C). They are functionally equivalent within the MMS series.

Q: What determines substitutability for MMS series connectors?

A: Substitutability is determined by matching: connector type (receptacle), position count (9), mating pitch (0.079"), mounting configuration (surface mount right-angle), contact finish (gold), current capacity (3.9A per contact), insulation material (LCP), and compliance status (ROHS3).

Q: Can these connectors be used in applications requiring different pitch specifications?

A: No. Both parts are specified for 0.079" (2.00mm) pitch only. Connectors with different pitch specifications are not interchangeable and require separate part selection.

Q: What is the moisture sensitivity classification for these parts?

A: Both parts carry MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

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

A: No. Both parts are ROHS3 compliant, carry identical ECCN (EAR99) and HTSUS classifications, and meet the same regulatory requirements.
