Substitute Part Grouping Explanation

Substitution eligibility for the MDF7-6P-2.54DSA(55) is determined by the following critical parameters:

Connector type (Header)
Contact type (Male Pin)
Number of positions (6)
Pitch spacing (0.100" / 2.54mm)
Mounting type (Through Hole)
Termination method (Solder)
Current rating (3A minimum)
Voltage rating (250V minimum)
Operating temperature range (-35°C ~ 85°C)
Material compliance (RoHS Compliant, UL94 V-0)

The MDF7-6P-2.54DSA(95) qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary difference lies in the connector style designation (board-to-cable/wire versus board-to-board) and product status (active versus obsolete), which does not affect electrical or mechanical compatibility for the specified application requirements.

Engineering Selection Recommendations

The MDF7-6P-2.54DSA(95) is the qualified substitute for the obsolete MDF7-6P-2.54DSA(55). Both components are manufactured by Hirose Electric Co Ltd within the same MDF7 series and maintain identical electrical and mechanical specifications across all critical parameters. The substitute part is currently in active production status with confirmed inventory availability, providing supply chain continuity for applications previously designed with the MDF7-6P-2.54DSA(55).

Both parts carry RoHS compliance certification and UL94 V-0 flammability rating, meeting the same regulatory and safety requirements. The voltage rating specification differs only in notation (250V versus 250VAC), representing the same electrical performance threshold. No design modifications or PCB layout changes are required when transitioning from the obsolete part to the substitute.

Frequently Asked Questions (FAQ)

Q: Can the MDF7-6P-2.54DSA(95) be used as a direct replacement for the MDF7-6P-2.54DSA(55)?

A: Yes. Both parts share identical electrical ratings (3A current, 250V voltage), mechanical dimensions, contact specifications, and material composition. The substitute is fully compatible with existing PCB designs and assembly processes.

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

A: The primary difference is product status. The MDF7-6P-2.54DSA(55) is obsolete, while the MDF7-6P-2.54DSA(95) is in active production. The connector style designation differs (board-to-board versus board-to-cable/wire), but this does not affect electrical or mechanical compatibility for the specified application.

Q: Are there any packaging differences between these parts?

A: The MDF7-6P-2.54DSA(55) packaging is not specified in available documentation. The MDF7-6P-2.54DSA(95) is supplied in bag packaging. Both parts maintain identical component specifications and performance characteristics.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the MDF7-6P-2.54DSA(55) and MDF7-6P-2.54DSA(95) are RoHS compliant and carry UL94 V-0 flammability certification. Both have Moisture Sensitivity Level 1 (Unlimited), indicating no special handling requirements during storage or assembly.

Q: What is the operating temperature range for these connectors?

A: Both parts operate across the temperature range of -35°C to 85°C, suitable for industrial and commercial applications within this thermal envelope.
