Key Parameters

Substitute Part Grouping Explanation

Substitution within the MMS-105 rectangular connector series is determined by alignment of the following critical parameters:

• Base product number (MMS-105)
• Number of positions (5)
• Pitch - mating (0.079" / 2.00mm)
• Connector type (Receptacle)
• Contact type (Female Socket)
• Mounting type (Surface Mount)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Contact finish - mating (Gold)
• Operating temperature range (-55°C ~ 125°C)
• Current rating (3.9A per Contact)
• Insulation material (Liquid Crystal Polymer)
• RoHS compliance status (ROHS3 Compliant)

The identified substitute part MMS-105-02-L-SV-P-TR maintains all critical electrical and mechanical parameters. Variation exists only in the post contact finish designation (K versus P suffix), which does not affect mating interface compatibility or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Both MMS-105-02-L-SV-K-TR and MMS-105-02-L-SV-P-TR are active products with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on inventory availability and supply chain requirements. The substitute part MMS-105-02-L-SV-P-TR maintains higher inventory levels at 3784 units compared to 1721 units for the primary part, providing improved availability for production planning.

Both connectors meet identical electrical specifications, mechanical dimensions, and environmental operating requirements. The post contact finish variation does not impact mating interface performance or system-level electrical characteristics.

Frequently Asked Questions (FAQ)

Q: What is the difference between MMS-105-02-L-SV-K-TR and MMS-105-02-L-SV-P-TR?

A: Both parts are 5-position rectangular receptacle connectors with identical mating pitch, contact configuration, and electrical ratings. The suffix designation (K versus P) indicates a variation in post contact finish specification. All mating interface parameters and electrical performance characteristics remain identical.

Q: Can MMS-105-02-L-SV-P-TR be used as a direct replacement for MMS-105-02-L-SV-K-TR?

A: Yes. Both parts share the same base product number (MMS-105), connector type, contact configuration, pitch, mounting method, and electrical ratings. They are mechanically and electrically compatible for board-to-board or cable applications.

Q: Are there any compatibility concerns with PCB layout or assembly?

A: No. Both parts have identical surface mount footprints, solder termination specifications, and insulation heights (0.177" / 4.50mm). PCB design files and assembly procedures require no modification when substituting between these parts.

Q: What is the operating temperature range for these connectors?

A: Both MMS-105-02-L-SV-K-TR and MMS-105-02-L-SV-P-TR operate across -55°C to 125°C, supporting applications in industrial, automotive, and extended temperature environments.

Q: Are these connectors RoHS compliant?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for electronic component procurement in regulated markets.

Q: What is the current rating per contact?

A: Both connectors are rated for 3.9A per contact, supporting standard signal and low-power distribution applications within the MMS series specifications.
