Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDF7C-25P-2.54DSA(55) is determined by the following critical parameters:

• Manufacturer series consistency (MDF7 family)
• Identical position count (25 positions)
• Matching pitch specification (0.100" / 2.54mm)
• Single-row configuration
• Through-hole mounting capability
• Solder termination method
• Tin contact finish on mating posts
• Overall pin length and stack height compatibility
• RoHS compliance and MSL rating equivalence

The substitute part MDF7C-25P-2.54DSA(95) meets all these criteria, representing an active production variant within the same connector series with functionally equivalent electrical and mechanical characteristics.

Frequently Asked Questions (FAQ)

Q: Can MDF7C-25P-2.54DSA(95) be used as a direct replacement for MDF7C-25P-2.54DSA(55)?

A: Yes. Both connectors share identical position count (25), pitch spacing (0.100" / 2.54mm), mounting type (through-hole), termination method (solder), and contact finish (tin). The mechanical and electrical interface characteristics are equivalent.

Q: What is the difference between the two part numbers?

A: The suffix designation (55 versus 95) indicates different manufacturing batches or packaging configurations within the same connector design. The MDF7C-25P-2.54DSA(55) is obsolete, while MDF7C-25P-2.54DSA(95) is in active production.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. The connectors are mechanically and electrically interchangeable. PCB footprints, mating interface dimensions, and solder pad layouts remain identical between the two variants.

Q: What packaging is available for the substitute part?

A: The MDF7C-25P-2.54DSA(95) is supplied in bag packaging. Verify packaging requirements for your procurement process.

Q: Do both parts meet current compliance standards?

A: Yes. Both the original and substitute parts are RoHS compliant and carry MSL rating 1 (unlimited moisture sensitivity level), meeting current regulatory requirements for electronic component use.
