• Electrical Ratings: Current rating of 3A and voltage rating of 250V or higher
• Mounting Configuration: Through-hole solder termination with push-pull fastening
• Material & Compliance: PBT insulation, tin-plated brass contacts, UL94 V-0 flammability rating, RoHS compliant

The substitute part MDF7B-9P-2.54DSA(95) meets all critical substitution criteria while offering active product status and improved procurement availability.

Parameter Comparison

Engineering Selection Recommendations

The MDF7B-9P-2.54DSA(95) is a direct functional equivalent to the obsolete MDF7B-9P-2.54DSA(55). Both parts maintain identical electrical specifications, mechanical dimensions, and material composition. The substitute part carries active product status from Hirose Electric Co Ltd, ensuring long-term availability and supply chain continuity. Both parts are RoHS compliant and carry UL94 V-0 flammability certification, meeting regulatory requirements for industrial and consumer applications. The overall contact length variance of 0.01mm (22.01mm vs 22.00mm) is within standard manufacturing tolerances and does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can MDF7B-9P-2.54DSA(95) be used as a direct replacement for MDF7B-9P-2.54DSA(55)?

A: Yes. Both parts are from the same MDF7 series with identical 9-position, 2.54mm pitch configuration, electrical ratings, and mechanical specifications. The substitute part is functionally equivalent and maintains the same solder termination and push-pull fastening interface.

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

A: The suffix designation (55) vs (95) indicates different packaging configurations. MDF7B-9P-2.54DSA(55) is obsolete, while MDF7B-9P-2.54DSA(95) is active with bag packaging. The functional connector specifications remain identical.

Q: Are there any compliance or certification differences?

A: No. Both parts are RoHS compliant, carry UL94 V-0 flammability rating, and maintain identical operating temperature ranges (-35°C ~ 85°C). Moisture sensitivity level is 1 (Unlimited) for both.

Q: Will the substitute part fit existing PCB designs?

A: Yes. The through-hole mounting configuration, contact pitch, and overall dimensions are identical. The 0.01mm variance in overall contact length is within standard manufacturing tolerance and does not affect board-level compatibility.

Q: What is the current availability status?

A: MDF7B-9P-2.54DSA(95) is active with 741 pieces in stock. MDF7B-9P-2.54DSA(55) is obsolete with limited remaining inventory of 898 pieces.
