MDF7-25P-2.54DSA(55) Equivalent & Substitute Parts

Part Overview

The MDF7-25P-2.54DSA(55) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole mounting applications. This 25-position, single-row connector operates at 3A current rating and 250V voltage rating with a 0.100" (2.54mm) pitch. The part is classified as obsolete, making identification of active equivalent models essential for ongoing procurement and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDF7-25P-2.54DSA(55) is determined by the following critical parameters:

• Connector Series & Pitch: Both parts must belong to the MDF7 series with 0.100" (2.54mm) mating pitch to ensure mechanical and electrical compatibility
• Position Count & Configuration: 25-position, single-row configuration is required for pin-to-pin compatibility
• Electrical Ratings: Current rating of 3A and voltage rating of 250V or higher must be maintained
• Contact Specifications: Male pin contacts with tin finish on brass material ensure equivalent electrical performance
• Mounting & Termination: Through-hole solder termination is mandatory for PCB integration compatibility
• Material & Compliance: PBT insulation material, UL94 V-0 flammability rating, and RoHS compliance must be preserved

The MDF7-25P-2.54DSA(95) qualifies as a direct substitute based on these parameters. The primary difference is product status (active vs. obsolete) and connector style designation, which does not affect electrical or mechanical interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

The MDF7-25P-2.54DSA(95) is the qualified substitute for the obsolete MDF7-25P-2.54DSA(55). Both parts maintain identical electrical and mechanical specifications across all critical parameters. The MDF7-25P-2.54DSA(95) carries active product status from Hirose Electric Co Ltd, ensuring ongoing availability and manufacturing support. Both parts are RoHS compliant and carry UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications. Current inventory availability is confirmed for the substitute part, supporting procurement continuity.

Frequently Asked Questions (FAQ)

Q: Are MDF7-25P-2.54DSA(55) and MDF7-25P-2.54DSA(95) pin-for-pin compatible?

A: Yes. Both parts feature identical 25-position, single-row configurations with 0.100" (2.54mm) pitch, square male pin contacts, and equivalent contact dimensions. Pin-to-pin compatibility is confirmed.

Q: What is the difference between the (55) and (95) designations?

A: The designations reflect different connector style classifications within the MDF7 series. The (55) variant is obsolete, while the (95) variant is active. Electrical and mechanical specifications remain equivalent.

Q: Can the MDF7-25P-2.54DSA(95) be used as a direct replacement in existing designs?

A: Yes. The substitute part maintains all critical electrical parameters (3A current rating, 250V voltage rating), mechanical dimensions, and material specifications. No design modifications are required.

Q: Are both parts RoHS compliant?

A: Yes. Both MDF7-25P-2.54DSA(55) and MDF7-25P-2.54DSA(95) are RoHS compliant with UL94 V-0 flammability certification.

Q: What is the packaging difference?

A: The MDF7-25P-2.54DSA(55) packaging is not specified in available data. The MDF7-25P-2.54DSA(95) is supplied in bag packaging. Verify packaging requirements with your procurement specifications.

Q: Is the voltage rating difference (250V vs. 250VAC) significant?

A: Both ratings specify 250V capacity. The (95) variant explicitly designates alternating current (AC) application. For DC applications, both parts are suitable. Confirm voltage type requirements for your specific application.
