Key Parameters

Substitute Part Grouping Explanation

The MDF7C-6P-2.54DSA(95) qualifies as a direct substitute based on the following critical parameters:

• Series Match: Both parts belong to the MDF7 series from Hirose Electric Co Ltd
• Position Count: Identical 6-position configuration
• Pitch Specification: Both maintain 0.100" (2.54mm) pitch spacing
• Mounting Method: Both are through-hole solder-terminated connectors
• Contact Finish: Both feature tin-plated contacts on mating and post surfaces
• Overall Dimensions: Pin length and stack height specifications are identical
• Electrical Ratings: Both support 3A current rating and 250VAC voltage rating
• Compliance: Both are RoHS compliant with MSL 1 rating
• Material Specification: Both use PBT insulation material with UL94 V-0 flammability rating

The primary distinction is product status: MDF7C-6P-2.54DSA(55) is obsolete, while MDF7C-6P-2.54DSA(95) maintains active status with current manufacturing availability.

Parameter Comparison
