Substitute Part Grouping Explanation

Substitution between MMS-113-02-L-DV-M-TR and MMS-113-02-L-DV-K-TR is based on electrical and mechanical parameter equivalence. Both parts share identical specifications across all critical substitution criteria:

• Connector type, position count, and row configuration
• Mating pitch and row spacing
• Surface mount termination and solder attachment
• Gold contact finish with identical thickness specification
• Current rating and operating temperature range
• Insulation material and contact geometry
• RoHS3 compliance and MSL 1 rating

The parts differ only in fastening type designation (M versus K suffix), which represents a manufacturing or design revision variant within the MMS-113 base product family. Both maintain full electrical and mechanical compatibility for board-level integration.

Parameter Comparison

Engineering Selection Recommendations

Both MMS-113-02-L-DV-M-TR and MMS-113-02-L-DV-K-TR are active production parts with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Current inventory availability and lead time requirements
• PCB layout and assembly process compatibility with tape-and-reel packaging
• Compliance requirements: both parts meet ROHS3 and carry EAR99 export classification
• Moisture handling: both parts carry MSL 1 rating, requiring no special storage or handling precautions

The MMS-113-02-L-DV-K-TR variant currently maintains higher inventory levels (1418 pcs versus 950 pcs), which may influence procurement decisions for high-volume production runs.

Frequently Asked Questions (FAQ)
