Engineering Selection Recommendations

The MDF7-8P-2.54DSA(96) is the qualified substitute for the obsolete MDF7-8P-2.54DSA(01). Both parts maintain identical electrical specifications, mechanical dimensions, and material certifications. The substitute part carries Active product status with current manufacturing availability, ensuring supply chain continuity.

Selection of MDF7-8P-2.54DSA(96) is supported by:

Identical electrical ratings: 3A current, 250V voltage
Matching mechanical specifications: 8 positions, 2.54mm pitch, through-hole mounting
Equivalent material compliance: UL94 V-0 flammability rating, RoHS compliant
Same contact materials and finishes: Brass with gold plating
Identical operating temperature range: -35°C to 85°C
Active product status with documented inventory availability

The application style designation difference (Board to Board versus Board to Cable/Wire) reflects connector mating interface classification and does not affect the header component itself.

Frequently Asked Questions (FAQ)

Q: Can MDF7-8P-2.54DSA(96) directly replace MDF7-8P-2.54DSA(01) in existing designs?

A: Yes. Both parts share identical electrical ratings (3A, 250V), mechanical dimensions (8 positions, 2.54mm pitch), contact materials (brass with gold finish), and operating temperature range (-35°C to 85°C). Through-hole solder termination and PCB footprints are identical.

Q: What is the significance of the application style difference (Board to Board vs. Board to Cable/Wire)?

A: The application style designation indicates the intended mating connector type. For the header component MDF7-8P-2.54DSA(96), this classification does not affect the physical or electrical characteristics of the part itself. The header remains compatible with both board-to-board and board-to-cable applications depending on the mating connector selected.

Q: Are there packaging differences between these parts?

A: MDF7-8P-2.54DSA(01) packaging is not specified in available documentation. MDF7-8P-2.54DSA(96) is supplied in bag packaging. This difference affects only handling and storage procedures, not component performance or compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS compliant, carry UL94 V-0 flammability rating, and maintain Moisture Sensitivity Level 1 (Unlimited). Electrical classification codes (ECCN: EAR99, HTSUS: 8536.69.4040) are identical.

Q: Why is MDF7-8P-2.54DSA(01) listed as obsolete?

A: Product status reflects manufacturer lifecycle decisions. The active substitute MDF7-8P-2.54DSA(96) provides equivalent functionality with current manufacturing support and documented inventory availability.
