Substitute Part Grouping Explanation

Substitution eligibility for the MDF7-6P-2.54DS(55) is determined by the following critical parameters:

Connector Type & Contact Configuration: Header with male pins
Position Count & Pitch: 6 positions at 0.100" (2.54mm) mating pitch
Mounting Geometry: Through-hole, right-angle orientation
Electrical Ratings: 3A current capacity and 250V voltage rating minimum
Material & Compliance: Brass contacts with tin finish, PBT insulation, UL94 V-0 rated, RoHS compliant
Operating Environment: -35°C to 85°C temperature range

The MDF7-6P-2.54DS(95) qualifies as a direct substitute based on matching all critical parameters. Both parts share identical series designation, position count, pitch, mounting type, electrical ratings, material composition, and compliance certifications. The primary distinction lies in product status and application context.

Engineering Selection Recommendations

The MDF7-6P-2.54DS(95) is the direct functional equivalent for the obsolete MDF7-6P-2.54DS(55). Both parts maintain identical electrical specifications, mechanical dimensions, material composition, and regulatory compliance certifications. The MDF7-6P-2.54DS(95) carries active product status from Hirose Electric Co Ltd, ensuring ongoing availability and manufacturing support.

For applications currently specified with MDF7-6P-2.54DS(55), transition to MDF7-6P-2.54DS(95) requires no design modification. The minor variance in mating contact length (0.293" versus 0.292") falls within standard manufacturing tolerances and does not affect functional compatibility. Both parts are RoHS compliant and carry identical UL94 V-0 flammability ratings.

Frequently Asked Questions (FAQ)

Q: Can MDF7-6P-2.54DS(95) be used as a direct replacement for MDF7-6P-2.54DS(55)?

A: Yes. Both parts share identical connector type, position count, pitch, mounting configuration, electrical ratings, and material specifications. The MDF7-6P-2.54DS(95) is the active production equivalent.

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

A: The primary difference is product status. MDF7-6P-2.54DS(55) is obsolete, while MDF7-6P-2.54DS(95) is active. The mating contact length differs by 0.001" (0.03mm), which is within standard manufacturing tolerance and does not affect mating performance.

Q: Are there packaging differences between these parts?

A: MDF7-6P-2.54DS(55) has unspecified packaging, while MDF7-6P-2.54DS(95) is supplied in bag packaging. This does not affect component functionality or electrical performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS compliant, carry UL94 V-0 flammability rating, and share identical moisture sensitivity level (MSL 1 - Unlimited).

Q: What electrical parameters must match for substitution?

A: Current rating (3A), voltage rating (250V), operating temperature range (-35°C to 85°C), and contact material/finish specifications must remain constant for functional equivalence.

Q: Can these connectors be used in board-to-cable applications?

A: The MDF7-6P-2.54DS(95) is specified for board-to-cable/wire applications, while MDF7-6P-2.54DS(55) is specified for board-to-board applications. Verify mating connector compatibility for your specific application context.
