Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MMS-102-01-LM-SH are identified based on strict electrical and mechanical parameter alignment within the MMS series. The substitution criteria are:

• Identical pitch specification: 0.079" (2.00mm) mating pitch
• Matching connector type: 2-position receptacle configuration
• Equivalent mounting: Through-hole, right-angle orientation
• Consistent contact materials and finishes: Gold mating surface with tin post finish
• Aligned current rating: 3.9A per contact capacity
• Compatible temperature range: -55°C to 125°C operation
• Same insulation material: Liquid Crystal Polymer (LCP)
• Regulatory compliance: ROHS3 compliant status

The MMS-102-01-L-SH qualifies as a direct substitute based on these parameters, with all electrical and mechanical specifications matching the primary part.

Parameter Comparison

Engineering Selection Recommendations

Both the MMS-102-01-LM-SH and MMS-102-01-L-SH are active production parts with ROHS3 compliance and equivalent electrical and mechanical specifications. The MMS-102-01-L-SH maintains higher inventory availability at 1,099 units compared to 681 units for the primary part, making it a viable alternative for procurement continuity. Both parts carry the same base product number (MMS-102) and share identical contact materials, finishes, and performance ratings. Selection between these parts should be based on supply chain availability and lead time requirements, as all functional parameters are equivalent.
