Key Parameters

Substitute Part Grouping Explanation

The MMS-104-01-L-SV qualifies as a direct substitute for the MMS-104-01-LM-SV based on the following critical parameters:

• Identical connector type (Receptacle)
• Identical number of positions (4)
• Identical mating pitch (0.079" / 2.00mm)
• Identical mounting type (Through Hole)
• Identical contact finish - mating (Gold)
• Identical current rating (3.9A per Contact)
• Identical operating temperature range (-55°C ~ 125°C)
• Identical insulation material (Liquid Crystal Polymer)
• Identical RoHS compliance status (ROHS3 Compliant)

Both parts belong to the MMS series and share the same base product number (MMS-104), confirming their functional equivalence for applications requiring 4-position rectangular connectors with these specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the MMS-104-01-LM-SV and MMS-104-01-L-SV are active production parts manufactured by Samtec Inc. and maintain identical ROHS3 compliance certification. The MMS-104-01-L-SV offers higher inventory availability (2683 units in stock versus 748 units), making it a practical alternative when supply considerations are relevant. Both parts carry the same ECCN (EAR99) and HTSUS classification, ensuring consistent regulatory treatment in procurement and logistics.

Selection between these parts should be based on inventory availability and lead time requirements, as all electrical, mechanical, and compliance parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can MMS-104-01-L-SV be used as a direct replacement for MMS-104-01-LM-SV?

A: Yes. Both parts are functionally identical across all critical parameters including connector type, position count, mating pitch, mounting method, contact finish, current rating, and operating temperature range. They share the same base product number (MMS-104) and belong to the same MMS series.

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

A: No. Both parts are ROHS3 compliant and carry identical ECCN and HTSUS classifications. Regulatory treatment is equivalent.

Q: What is the primary distinction between these two part numbers?

A: The primary distinction is inventory availability. The MMS-104-01-L-SV has significantly higher stock levels (2683 units) compared to the MMS-104-01-LM-SV (748 units). Additionally, the MMS-104-01-L-SV carries an MSL rating of 1 (Unlimited) and includes REACH Unaffected status in its documentation.

Q: Are the mechanical dimensions identical?

A: Yes. Both parts share identical insulation height (0.175" / 4.45mm), contact length (0.115" / 2.92mm), and all other mechanical specifications.

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

A: Yes. The identical pitch (0.079" / 2.00mm), mounting type (Through Hole), and all mechanical dimensions ensure direct PCB footprint compatibility.
