MDF7-12P-2.54DSA(01) Equivalent & Substitute Parts

Part Overview

The MDF7-12P-2.54DSA(01) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for through-hole mounting applications. This 12-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 production and maintenance applications.

Substitute Part Grouping Explanation

Substitution of the MDF7-12P-2.54DSA(01) is determined by the following critical parameters:

Series Compatibility: Both parts belong to the MDF7 series, ensuring mechanical and electrical compatibility
Position Count: 12 positions maintained across all substitutes
Pitch Specification: 0.100" (2.54mm) mating pitch is identical
Connector Type & Contact Type: Header with male pin configuration remains constant
Electrical Ratings: Current rating (3A) and voltage rating (250V) are preserved
Mounting Method: Through-hole termination with solder connection maintained
Material & Finish: Brass contacts with gold mating finish and PBT insulation material consistent
Temperature Range: Operating temperature -35°C ~ 85°C identical
Compliance: RoHS compliance and UL94 V-0 flammability rating maintained

The primary distinction between the main part and substitute relates to product status (obsolete vs. active) and packaging configuration (board-to-board vs. board-to-cable/wire style).

Engineering Selection Recommendations

The MDF7-12P-2.54DSA(96) serves as the active equivalent for the obsolete MDF7-12P-2.54DSA(01). Both parts maintain identical electrical and mechanical specifications across all critical parameters, including pitch, position count, current and voltage ratings, operating temperature range, and material compliance.

The MDF7-12P-2.54DSA(96) is currently in active production status with confirmed inventory availability (716 pcs), whereas the MDF7-12P-2.54DSA(01) is obsolete. Both parts carry RoHS compliance certification and UL94 V-0 flammability rating, meeting equivalent regulatory requirements.

The distinction in connector style (board-to-board vs. board-to-cable/wire) reflects application-specific design variations within the same series. Selection between these variants depends on the specific circuit board interface requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Are MDF7-12P-2.54DSA(01) and MDF7-12P-2.54DSA(96) electrically interchangeable?

A: Yes. Both parts share identical electrical specifications: 3A current rating, 250V voltage rating, and -35°C to 85°C operating temperature range. The contact material, finish, and gauge are equivalent.

Q: What is the difference between "Board to Board" and "Board to Cable/Wire" styles?

A: The style designation indicates the intended mating interface. Board-to-board connectors mate with corresponding receptacle connectors on another PCB. Board-to-cable/wire connectors mate with cable assemblies or wire harnesses. The electrical and mechanical pin specifications remain identical.

Q: Can I use MDF7-12P-2.54DSA(96) as a direct replacement for MDF7-12P-2.54DSA(01)?

A: Direct replacement is possible when the application circuit board design accommodates the board-to-cable/wire connector style. Verify that the mating interface and connector orientation align with your specific application requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both MDF7-12P-2.54DSA(01) and MDF7-12P-2.54DSA(96) carry RoHS compliance certification and meet UL94 V-0 flammability standards.

Q: What is the pitch specification for these connectors?

A: Both parts operate at 0.100" (2.54mm) mating pitch with 12 positions in a single row configuration.

Q: Does packaging differ between these parts?

A: The MDF7-12P-2.54DSA(01) packaging is not specified. The MDF7-12P-2.54DSA(96) is supplied in bag packaging. Verify packaging requirements for your procurement and assembly processes.
