Key Parameters

Substitute Part Grouping Explanation

The MDF7C-12DP-2.54DSA(96) qualifies as a direct substitute based on the following critical parameters:

• Connector Configuration: Both parts maintain 12 positions in a 2-row arrangement with 0.100" (2.54mm) pitch and row spacing
• Electrical Specifications: Identical current rating (3A) and voltage rating (250VAC)
• Physical Interface: Matching through-hole solder termination with gold contact finish
• Mechanical Compatibility: Same mounting type and contact material (brass with polybutylene terephthalate insulation)
• Regulatory Compliance: Both parts are RoHS compliant with MSL 1 rating
• Operating Environment: Identical temperature range (-35°C to 85°C)

The primary distinction is product status: the substitute part MDF7C-12DP-2.54DSA(96) is active and available, whereas the original part is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The MDF7C-12DP-2.54DSA(96) is the appropriate selection for applications currently specified with the obsolete MDF7C-12DP-2.54DSA. Both parts are manufactured by Hirose Electric Co Ltd within the same MDF7 series and maintain identical electrical, mechanical, and environmental specifications. The substitute part carries active product status with confirmed inventory availability, ensuring supply chain continuity. Both components meet RoHS compliance requirements and carry MSL 1 ratings suitable for standard storage and handling conditions. The packaging difference (bag versus unspecified) does not affect functional compatibility or performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can MDF7C-12DP-2.54DSA(96) be used as a direct replacement for MDF7C-12DP-2.54DSA?

A: Yes. Both parts share identical electrical ratings (3A, 250VAC), mechanical configuration (12 positions, 2 rows, 0.100" pitch), mounting method (through-hole solder), and contact specifications (gold-plated brass). The substitute part is the active production variant of the same connector family.

Q: What is the significance of the "(96)" designation in the substitute part number?

A: The "(96)" suffix indicates a packaging or manufacturing revision code specific to Hirose Electric Co Ltd's part numbering system. This does not affect electrical or mechanical compatibility with the original part specification.

Q: Are there any environmental or compliance differences between these parts?

A: No. Both parts are RoHS compliant, carry MSL 1 ratings, and operate across the identical temperature range (-35°C to 85°C). Regulatory classifications (ECCN: EAR99, HTSUS: 8536.69.4040) are identical.

Q: What is the primary reason for substitution?

A: The original MDF7C-12DP-2.54DSA is classified as obsolete. The MDF7C-12DP-2.54DSA(96) is the active equivalent with confirmed inventory availability, ensuring design continuity and production support.

Q: Are there any dimensional differences that would affect PCB layout?

A: No dimensional variations are specified between the parts. Both maintain the same through-hole mounting footprint and connector geometry, requiring no PCB redesign.
