Key Parameters

Substitute Part Grouping Explanation

Substitution for the MDF7C-7P-2.54DSA(55) is determined by the following critical parameters:

• Connector Configuration: 7 positions, single row, 0.100" (2.54mm) pitch
• Mounting and Termination: Through-hole solder termination
• Physical Dimensions: Overall pin length of 0.984" (25.000mm) and stack height of 0.728" (18.500mm)
• Contact Material and Finish: Tin-plated brass contacts
• Compliance: RoHS compliant status
• Series Compatibility: MDF7 series designation

The substitute part MDF7C-7P-2.54DSA(95) maintains identical electrical and mechanical specifications within the MDF7 series, differing only in packaging format and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The MDF7C-7P-2.54DSA(95) is the direct substitute for the obsolete MDF7C-7P-2.54DSA(55). Both parts are manufactured by Hirose Electric Co Ltd within the same MDF7 series and share identical electrical and mechanical specifications. The substitute part maintains RoHS compliance and is currently in active production status, ensuring long-term availability and supply chain continuity.

Selection of the MDF7C-7P-2.54DSA(95) is appropriate for applications requiring the same connector footprint, pitch spacing, and through-hole mounting configuration. The active product status of the substitute eliminates obsolescence risk for new designs and ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between MDF7C-7P-2.54DSA(55) and MDF7C-7P-2.54DSA(95)?

A: The primary difference is product status and packaging. The MDF7C-7P-2.54DSA(55) is obsolete, while the MDF7C-7P-2.54DSA(95) is active production. Both maintain identical 7-position, 0.100" pitch through-hole solder termination specifications.

Q: Are these connectors mechanically interchangeable?

A: Yes. Both connectors share identical overall pin length (0.984"), stack height (0.728"), and post length (0.118"), ensuring direct mechanical compatibility in PCB layouts and mating applications.

Q: What are the electrical specifications for these connectors?

A: The MDF7C-7P-2.54DSA(95) is rated for 3A per contact at 250VAC with an operating temperature range of -35°C to 85°C. These specifications apply to the substitute part for the obsolete MDF7C-7P-2.54DSA(55).

Q: Are both parts RoHS compliant?

A: Yes. Both the MDF7C-7P-2.54DSA(55) and MDF7C-7P-2.54DSA(95) are RoHS compliant with Moisture Sensitivity Level 1 (unlimited shelf life).

Q: What packaging formats are available?

A: The MDF7C-7P-2.54DSA(95) is supplied in bag packaging. Packaging specifications for the obsolete MDF7C-7P-2.54DSA(55) were not specified in available documentation.
