Key Parameters

Substitute Part Grouping Explanation

The MDF7-3S-2.54DSA(96) qualifies as a direct substitute based on the following critical parameters that determine functional compatibility:

• Series Match: Both parts belong to the MDF7 series
• Position Count: Identical 3-position configuration
• Pitch Specification: Both use 0.100" (2.54mm) mating pitch
• Connector Type: Both are receptacle, bottom entry connectors
• Electrical Ratings: Matching 3A current and 250VAC voltage ratings
• Mounting Method: Both employ through-hole solder termination
• Contact Configuration: Identical female socket, square contact geometry
• Temperature Range: Identical -35°C ~ 85°C operating specification
• Material Compliance: Both meet UL94 V-0 flammability rating

The primary distinction is product status: MDF7-3S-2.54DSA(56) is obsolete, while MDF7-3S-2.54DSA(96) is active with higher inventory availability.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can MDF7-3S-2.54DSA(96) be used as a direct replacement for MDF7-3S-2.54DSA(56)?

A: Yes. Both connectors share identical electrical ratings (3A, 250VAC), mechanical dimensions, contact geometry, and operating temperature range (-35°C ~ 85°C). The parts are functionally interchangeable in all applications where the original part was specified.

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

A: The primary differences are product status and packaging. MDF7-3S-2.54DSA(56) is obsolete, while MDF7-3S-2.54DSA(96) is active. The (96) variant is supplied in bulk packaging and includes RoHS compliance documentation. All electrical and mechanical parameters are identical.

Q: Are there any compatibility concerns with PCB layout or footprint?

A: No. Both parts use identical through-hole mounting specifications, pitch (0.100" / 2.54mm), and contact post dimensions (0.118" / 3.00mm). PCB footprints designed for either part are fully compatible with the other.

Q: What is the inventory situation for these parts?

A: MDF7-3S-2.54DSA(56) has 679 pieces available as new original stock. MDF7-3S-2.54DSA(96) has 1109 pieces available. For new production, the (96) variant is recommended due to higher availability and active status.

Q: Are both parts RoHS compliant?

A: MDF7-3S-2.54DSA(96) is explicitly RoHS compliant. RoHS status for MDF7-3S-2.54DSA(56) is not specified in the available documentation.
