Key Parameters

Substitute Part Grouping Explanation

Substitution of the MDF7C-8P-2.54DSA(55) is based on the following critical parameters that must remain consistent:

• Connector Series: MDF7 (same manufacturer family)
• Number of Positions: 8 positions
• Pitch Specification: 0.100" (2.54mm)
• Mounting Configuration: Through Hole
• Termination Method: Solder
• Contact Finish: Tin-plated
• RoHS Compliance: RoHS Compliant
• Electrical Ratings: Voltage and current capacity

The substitute part MDF7C-8P-2.54DSA(95) belongs to the same MDF7 series and maintains identical position count, pitch, mounting type, and termination specifications. The primary distinction is the product status transition from obsolete to active, indicating continued manufacturer support and availability.

Parameter Comparison

Engineering Selection Recommendations

The MDF7C-8P-2.54DSA(95) is the direct substitute for the obsolete MDF7C-8P-2.54DSA(55). Both parts maintain identical mechanical and electrical interface specifications within the MDF7 series. The substitute part carries active product status, ensuring ongoing manufacturer support, availability, and compliance with current RoHS regulations. The transition from obsolete to active status provides supply chain continuity without requiring design modifications. Both parts are classified as Moisture Sensitivity Level 1, indicating no special handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can MDF7C-8P-2.54DSA(95) be used as a direct replacement for MDF7C-8P-2.54DSA(55)?

A: Yes. Both connectors share identical pitch (0.100" / 2.54mm), position count (8), mounting type (through hole), termination method (solder), and contact finish (tin). The primary difference is product status; the substitute is active while the original is obsolete.

Q: What is the significance of the different part number suffixes (55 vs 95)?

A: The suffix designates the manufacturing revision or packaging variant within the MDF7C-8P-2.54DSA base product line. The (95) variant is the current active production version.

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

A: No. Overall pin length (0.984"), post length (0.118"), and stack height specifications are identical between both parts, ensuring mechanical compatibility with existing PCB layouts and mating connectors.

Q: What are the electrical specifications for the substitute part?

A: The MDF7C-8P-2.54DSA(95) is rated for 3A current and 250VAC voltage. These specifications apply to the connector's electrical capacity per contact.

Q: Are both parts RoHS compliant?

A: Yes. Both the MDF7C-8P-2.54DSA(55) and MDF7C-8P-2.54DSA(95) are RoHS compliant and carry Moisture Sensitivity Level 1 classification.

Q: What packaging is available for the substitute part?

A: The MDF7C-8P-2.54DSA(95) is supplied in bag packaging.
