Key Parameters

Substitute Part Grouping Explanation

Substitution for the MDF7C-9P-2.54DSA(55) is determined by the following critical parameters:

• Number of Positions: 9
• Pitch: 0.100" (2.54mm)
• Number of Rows: 1
• Mounting Type: Through Hole
• Termination: Solder
• Contact Finish: Tin
• Overall Pin Length: 0.984" (25.000mm)
• Series Compatibility: MDF7

The substitute part MDF7C-9P-2.54DSA(95) maintains identical electrical and mechanical specifications across all critical parameters. Both parts belong to the same MDF7 series and share the same base product number (MDF7C), ensuring mechanical and electrical compatibility. The primary distinction is product status: the substitute part is active and currently available, whereas the original part is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The MDF7C-9P-2.54DSA(95) is the direct substitute for the obsolete MDF7C-9P-2.54DSA(55). Both parts are manufactured by Hirose Electric Co Ltd within the same MDF7 series and share identical mechanical and electrical specifications for all critical parameters.

Selection criteria:

• Both parts are RoHS Compliant, meeting regulatory requirements for restricted substances.
• Both parts carry MSL Rating 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.
• The substitute part is currently in active production status with confirmed inventory availability (964 Pcs), whereas the original part is obsolete.
• All dimensional specifications, contact configurations, and termination methods are identical between the two parts.

For new designs or component replenishment, the MDF7C-9P-2.54DSA(95) should be specified. For legacy systems currently using the MDF7C-9P-2.54DSA(55), direct substitution is electrically and mechanically compatible without design modification.

Frequently Asked Questions (FAQ)

Q: Can MDF7C-9P-2.54DSA(95) be used as a direct replacement for MDF7C-9P-2.54DSA(55)?

A: Yes. Both parts are identical in electrical and mechanical specifications. The substitute part is the active production equivalent of the obsolete original part.

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

A: The suffix designation (55 vs. 95) indicates different packaging or manufacturing batches. The electrical and mechanical specifications remain identical. The MDF7C-9P-2.54DSA(95) is currently in active production, while the MDF7C-9P-2.54DSA(55) is obsolete.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. Both parts share the same 9-position, 0.100" pitch configuration, through-hole mounting, and tin-plated contact finish. PCB footprints and mating connectors designed for one part will function identically with the other.

Q: What are the key parameters that define substitutability for this connector?

A: The critical parameters are: 9 positions, 0.100" (2.54mm) pitch, single row configuration, through-hole mounting, solder termination, and tin contact finish. Any substitute must match all these specifications.

Q: Is the substitute part RoHS compliant?

A: Yes. The MDF7C-9P-2.54DSA(95) is RoHS Compliant, matching the compliance status of the original part.

Q: What is the current rating and voltage rating for these connectors?

A: The substitute part is rated for 3A current and 250VAC voltage. These ratings apply to the connector contacts and should be verified against your specific application requirements.
