Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDF7-14D-2.54DSA(55) is determined by strict equivalence across the following critical parameters:

• Connector type: Receptacle, bottom entry configuration
• Position count: 14 positions
• Pitch specification: 0.100" (2.54mm) mating pitch with 0.100" (2.54mm) row spacing
• Mounting method: Through-hole solder termination
• Fastening mechanism: Push-pull
• Electrical ratings: 3A current, 250VAC voltage
• Operating temperature range: -35°C ~ 85°C
• Insulation material: Polyamide (PA), Nylon
• Contact material: Phosphor bronze with tin finish

The MDF7-14D-2.54DSA(95) qualifies as a direct substitute based on identical values across all these parameters. Variations in contact finish thickness and packaging do not affect functional compatibility in standard applications.

Parameter Comparison

Engineering Selection Recommendations

The MDF7-14D-2.54DSA(95) is the direct substitute for the obsolete MDF7-14D-2.54DSA(55). Both parts maintain identical electrical and mechanical specifications across all functional parameters. The primary distinction is product status: the MDF7-14D-2.54DSA(95) is currently active and available in bulk packaging, whereas the original part is obsolete.

The MDF7-14D-2.54DSA(95) carries RoHS compliance certification, providing additional regulatory alignment for new designs and procurement cycles. Contact finish thickness on the mating surface differs between the two parts (39.4µin versus 78.7µin), but this variation does not affect electrical performance or mechanical compatibility in standard board-to-board applications.

Frequently Asked Questions (FAQ)

Q: Can MDF7-14D-2.54DSA(95) be used as a direct replacement for MDF7-14D-2.54DSA(55)?

A: Yes. Both connectors share identical specifications for connector type, position count, pitch, mounting method, termination, fastening mechanism, and electrical ratings. The parts are mechanically and electrically interchangeable.

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

A: The primary differences are product status and packaging. The MDF7-14D-2.54DSA(55) is obsolete, while the MDF7-14D-2.54DSA(95) is active and available in bulk packaging. The MDF7-14D-2.54DSA(95) also carries RoHS compliance certification. Contact finish thickness on the mating surface differs slightly but does not impact functional compatibility.

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

A: No compatibility concerns exist. Both parts are from the same MDF7 series, maintain identical mechanical dimensions, and support the same electrical specifications. PCB footprints and mating connector requirements remain unchanged.

Q: What is the packaging difference?

A: The MDF7-14D-2.54DSA(55) packaging specification is not provided. The MDF7-14D-2.54DSA(95) is supplied in bulk packaging, which is standard for active production components.

Q: Does RoHS compliance affect substitution decisions?

A: The MDF7-14D-2.54DSA(95) is RoHS compliant. If your application or regulatory environment requires RoHS compliance, the substitute part meets this requirement. The original part's RoHS status is not specified.
