MDF7-12P-2.54DS(55) Equivalent & Substitute Parts

Part Overview

The MDF7-12P-2.54DS(55) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole, right-angle board-to-board applications with 12 positions at 0.100" (2.54mm) pitch. This connector is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity. The substitute part MDF7-12P-2.54DS(95) provides functional equivalence with current product status and availability.

Key Parameters

Substitute Part Grouping Explanation

The MDF7-12P-2.54DS(95) qualifies as a direct substitute based on the following critical parameters:

• Identical manufacturer (Hirose Electric Co Ltd) and base series (MDF7)
• Matching connector type, contact type, and gender (Header, Male Pin)
• Identical number of positions (12) and mating pitch (0.100" / 2.54mm)
• Identical electrical ratings (3A current, 250V voltage)
• Identical operating temperature range (-35°C ~ 85°C)
• Identical material specifications (Brass contacts, PBT insulation, Tin finish)
• Identical compliance certifications (RoHS Compliant, UL94 V-0, MSL 1)

The primary difference is product status: MDF7-12P-2.54DS(55) is obsolete, while MDF7-12P-2.54DS(95) is active with current inventory availability. The connector style designation change from Board to Board to Board to Cable/Wire reflects packaging variation rather than functional incompatibility for mating interface purposes.

Parameter Comparison

Engineering Selection Recommendations

The MDF7-12P-2.54DS(95) is the appropriate selection for new designs and procurement activities. This part maintains active product status with Hirose Electric Co Ltd and carries full compliance certifications (RoHS, UL94 V-0). All electrical, mechanical, and thermal specifications are identical to the obsolete MDF7-12P-2.54DS(55), ensuring direct functional equivalence in applications requiring 12-position, 2.54mm pitch through-hole headers with 3A/250V ratings.

For existing designs currently using MDF7-12P-2.54DS(55), transition to MDF7-12P-2.54DS(95) is supported without circuit modification or re-qualification, provided the connector interface remains unchanged.

Frequently Asked Questions (FAQ)

Q: Can MDF7-12P-2.54DS(95) directly replace MDF7-12P-2.54DS(55) in existing assemblies?

A: Yes. Both parts share identical mating pitch (0.100" / 2.54mm), contact configuration (12 male pins), electrical ratings (3A/250V), and mechanical mounting specifications (through-hole, right-angle). The mating interface is fully compatible.

Q: What is the significance of the part number suffix change from (55) to (95)?

A: The suffix designates packaging and product status variants within the MDF7 series. MDF7-12P-2.54DS(55) is obsolete; MDF7-12P-2.54DS(95) is the active equivalent with current manufacturing and inventory support.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical certifications: RoHS Compliant, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity level. Electrical and thermal specifications are identical.

Q: What is the contact length difference between these parts?

A: Contact length - mating differs slightly (0.292" / 7.42mm versus 0.293" / 7.45mm), representing a 0.03mm tolerance variation within normal manufacturing specifications. This does not affect functional compatibility or mating performance.

Q: Is the packaging difference (unspecified versus Bag) significant for component selection?

A: Packaging designation reflects distribution format only and does not affect electrical or mechanical performance. Both parts are suitable for automated assembly and manual placement applications.
