Substitute Part Grouping Explanation

The substitute part MDF7B-8P-2.54DSA(96) is classified as a direct equivalent based on the following critical parameters:

• Connector Series: Both parts belong to the MDF7 series
• Position Count: 8 positions maintained
• Pitch Specification: 0.100" (2.54mm) identical
• Contact Type: Male pin configuration unchanged
• Electrical Ratings: 3A current and 250V voltage maintained
• Mounting Method: Through-hole solder termination consistent
• Operating Temperature Range: -35°C ~ 85°C identical
• Material Specifications: Brass contacts with PBT insulation, gold-plated mating surface
• Compliance: RoHS compliant, UL94 V-0 flammability rating, MSL 1

The primary distinction is product status: MDF7B-8P-2.54DSA(96) carries active status with current manufacturing availability, whereas MDF7B-8P-2.54DSA(01) is obsolete.

Parameter Comparison

Engineering Selection Recommendations

MDF7B-8P-2.54DSA(96) is the active equivalent for the obsolete MDF7B-8P-2.54DSA(01). Both parts maintain identical electrical specifications, mechanical dimensions, and material compositions. The substitute part carries active product status with current manufacturing support from Hirose Electric Co Ltd. Both parts are RoHS compliant and carry UL94 V-0 flammability certification, meeting equivalent compliance requirements. The overall contact length variance of 0.01mm (22.01mm versus 22.00mm) falls within standard manufacturing tolerances and does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Are MDF7B-8P-2.54DSA(01) and MDF7B-8P-2.54DSA(96) mechanically interchangeable?

A: Yes. Both parts maintain identical pitch (0.100" / 2.54mm), position count (8), contact geometry, and mounting configuration. The 0.01mm variance in overall contact length is within manufacturing tolerance and does not affect board-level compatibility.

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

A: The primary difference is product status and packaging. MDF7B-8P-2.54DSA(01) is obsolete, while MDF7B-8P-2.54DSA(96) is active with current manufacturing availability. The (96) variant is supplied in bag packaging.

Q: Can MDF7B-8P-2.54DSA(96) replace MDF7B-8P-2.54DSA(01) in existing designs?

A: Yes. Electrical ratings (3A, 250V), operating temperature range (-35°C ~ 85°C), and all mechanical specifications are identical. Both parts use identical contact materials, finishes, and insulation composition.

Q: Are both parts RoHS compliant?

A: Yes. Both MDF7B-8P-2.54DSA(01) and MDF7B-8P-2.54DSA(96) are RoHS compliant with UL94 V-0 flammability rating and MSL 1 moisture sensitivity level.

Q: What is the voltage rating difference noted in the specifications?

A: MDF7B-8P-2.54DSA(01) lists 250V while MDF7B-8P-2.54DSA(96) specifies 250VAC. Both represent equivalent voltage handling capability for this connector class.
