Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDF7-10P-2.54DS(55) is determined by the following critical parameters:

• Connector Series & Pitch: Must remain MDF7 series with 0.100" (2.54mm) mating pitch to ensure mechanical and electrical compatibility with existing mating connectors
• Position Count & Contact Type: 10 positions with male pin contacts are required for direct functional equivalence
• Mounting Configuration: Through-hole, right-angle mounting must be maintained for PCB layout compatibility
• Electrical Ratings: Current rating of 3A and voltage rating of 250V establish the minimum electrical performance threshold
• Material & Compliance: Brass contacts with tin finish, PBT insulation, UL94 V-0 flammability rating, and RoHS compliance ensure regulatory and environmental compatibility

The MDF7-10P-2.54DS(95) qualifies as a direct substitute based on these parameters, with the primary distinction being product status (active versus obsolete) and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The MDF7-10P-2.54DS(95) is the direct substitute for the obsolete MDF7-10P-2.54DS(55). Both components maintain identical electrical and mechanical specifications across all critical parameters, including pitch, position count, contact configuration, current and voltage ratings, and operating temperature range. The substitute part carries active product status from Hirose Electric Co Ltd, ensuring ongoing availability and supply chain continuity.

Both parts meet RoHS compliance requirements and carry UL94 V-0 flammability certification, satisfying regulatory and safety standards. The primary distinction between the two variants is packaging format (bag versus unspecified for the original), which does not affect functional performance or electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can MDF7-10P-2.54DS(95) be used as a direct replacement for MDF7-10P-2.54DS(55)?

A: Yes. Both connectors share identical electrical ratings (3A, 250V), mechanical configuration (10-position, 0.100" pitch, through-hole right-angle), contact materials (brass with tin finish), and operating temperature range (-35°C to 85°C). The substitute part is currently in active production status.

Q: What is the significance of the different part number suffixes (55 versus 95)?

A: The suffix designates packaging and distribution channel variants within the MDF7 series. The MDF7-10P-2.54DS(95) is supplied in bag packaging and maintains active product status, while the MDF7-10P-2.54DS(55) is obsolete. Functional and electrical specifications remain identical.

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

A: No compatibility concerns exist. Both parts are mechanically and electrically interchangeable. PCB footprints, mating connector interfaces, and electrical performance are identical. Solder termination and through-hole mounting specifications are consistent across both variants.

Q: Does the substitute part meet the same compliance standards?

A: Yes. The MDF7-10P-2.54DS(95) maintains RoHS compliance and UL94 V-0 flammability certification identical to the original part. Moisture sensitivity level (MSL 1 - Unlimited) is also equivalent.

Q: What should be considered when transitioning from the obsolete to the active part?

A: Procurement should prioritize the MDF7-10P-2.54DS(95) for new designs and ongoing production. Inventory management of the obsolete variant should account for its discontinued status. No design modifications are required for the transition.
