Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MMS-113-02-L-DV-P is determined by the following critical parameters:

• Connector Type & Contact Configuration: Must be a receptacle with female socket contacts
• Position Count & Arrangement: Exactly 26 positions in a 2-row configuration
• Pitch Specifications: Mating pitch of 0.079" (2.00mm) with identical row spacing
• Mounting & Termination: Surface mount with solder termination
• Fastening Mechanism: Push-pull fastening type
• Contact Material & Finish: Gold-plated mating contacts on phosphor bronze base
• Environmental Compliance: RoHS compliance and MSL rating of 1

The substitute part 55510-126LF (Amphenol ICC/FCI Minitek® 2.00mm series) meets all critical substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the MMS-113-02-L-DV-P and 55510-126LF are active production parts with full RoHS compliance and unlimited moisture sensitivity ratings. Selection between these parts should be based on the following factors:

MMS-113-02-L-DV-P (Samtec): Select this part when the application requires the higher current rating of 3.9A per contact and ROHS3 compliance certification is mandatory.

55510-126LF (Amphenol ICC): Select this part when supply availability is prioritized (10551 units in stock versus 1145 units) or when the 2A current rating per contact is sufficient for the application. This part carries UL94 V-0 material flammability rating and is suitable for general purpose, industrial, and medical applications.

Both parts share identical mechanical dimensions, pitch specifications, operating temperature range, and contact configuration, ensuring direct substitution capability at the board level.

Frequently Asked Questions (FAQ)

Q: Can the 55510-126LF directly replace the MMS-113-02-L-DV-P in existing designs?

A: Yes, at the mechanical and electrical interface level. Both connectors feature identical 26-position, 2-row configurations with 0.079" (2.00mm) pitch, surface mount solder termination, and push-pull fastening. However, verify that your application's current requirements do not exceed 2A per contact, as the Amphenol part has a lower current rating (2A versus 3.9A).

Q: What is the difference in gold plating thickness between these parts?

A: The MMS-113-02-L-DV-P has 10.0µin (0.25µm) gold plating on mating contacts, while the 55510-126LF has 30.0µin (0.76µm). The thicker plating on the Amphenol part provides enhanced durability and contact resistance characteristics over extended mating cycles.

Q: Are both parts suitable for medical applications?

A: The 55510-126LF is explicitly rated for medical applications. The MMS-113-02-L-DV-P does not list medical applications in its specification data. Confirm application suitability with your design requirements and regulatory standards.

Q: What is the difference in RoHS compliance between ROHS3 and RoHS Compliant?

A: ROHS3 refers to the third iteration of the RoHS directive with updated substance restrictions. Both parts meet RoHS requirements; the MMS-113-02-L-DV-P carries the more recent ROHS3 certification while the 55510-126LF carries standard RoHS compliance. Both are acceptable for RoHS-regulated markets.

Q: Which part should I select for new designs?

A: For new designs, evaluate current requirements first. If your circuit requires more than 2A per contact, the MMS-113-02-L-DV-P is necessary. If 2A per contact is sufficient, the 55510-126LF offers superior stock availability and thicker gold plating for improved contact longevity.

Q: Are there any packaging or handling differences?

A: Both parts are supplied in tube packaging with MSL 1 (unlimited) moisture sensitivity rating, requiring no special storage or handling precautions beyond standard component care.
