Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDF7-8P-2.54DSA(55) is determined by the following critical parameters:

• Pitch and Position Count: 0.100" (2.54mm) pitch with 8 positions
• Connector Type and Contact Configuration: Header with male pins
• Mounting and Termination: Through-hole solder termination
• Electrical Ratings: 3A current and 250V voltage minimum
• Physical Dimensions: Contact length, insulation height, and overall form factor
• Material and Compliance: PBT insulation, brass contacts with tin finish, UL94 V-0 flammability rating

The MDF7-8P-2.54DSA(95) qualifies as a direct substitute based on matching all critical electrical, mechanical, and material specifications. The primary distinction lies in application style (board-to-cable/wire versus board-to-board) and product status (active versus obsolete).

Parameter Comparison

Engineering Selection Recommendations

The MDF7-8P-2.54DSA(95) is the qualified substitute for the obsolete MDF7-8P-2.54DSA(55). Both components share identical electrical ratings, mechanical dimensions, and material specifications. The substitute maintains full compatibility with the original part's functional requirements.

The MDF7-8P-2.54DSA(95) offers the advantage of active product status, ensuring continued availability and supply chain stability. The component meets ROHS3 compliance and is REACH unaffected, providing enhanced regulatory alignment for new designs and legacy system support.

The distinction in application style (board-to-cable/wire versus board-to-board) does not affect electrical or mechanical interchangeability when used in equivalent circuit configurations. Selection between these variants depends on the specific interconnection topology of the target application.

Frequently Asked Questions (FAQ)

Q: Can the MDF7-8P-2.54DSA(95) directly replace the MDF7-8P-2.54DSA(55)?
