Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDF7C-20DP-2.54DSA is determined by strict alignment of the following critical parameters:

• Connector Series: MDF7 (same manufacturer family)
• Number of Positions: 20 (exact match required)
• Pitch Specification: 0.100" (2.54mm) (exact match required)
• Number of Rows: 2 (exact match required)
• Row Spacing: 0.100" (2.54mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Termination Method: Solder (exact match required)
• Contact Finish: Gold (exact match required)
• RoHS Compliance: RoHS Compliant (required for regulatory alignment)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The substitute part MDF7C-20DP-2.54DSA(96) meets all critical parameters and is classified as an active product, providing continuity for applications currently using the obsolete main part.

Parameter Comparison

Engineering Selection Recommendations

The MDF7C-20DP-2.54DSA(96) is the direct substitute for the obsolete MDF7C-20DP-2.54DSA. Both parts are manufactured by Hirose Electric Co Ltd within the same MDF7 series and share identical electrical and mechanical specifications for the critical parameters governing connector compatibility: 20-position configuration, 0.100" (2.54mm) pitch, dual-row layout, through-hole mounting, and solder termination.

The substitute part carries active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain RoHS compliance and identical moisture sensitivity ratings, supporting regulatory and environmental requirements. The substitute part provides documented electrical performance specifications (3A current rating, 250VAC voltage rating) and material composition (brass contacts, PBT insulation), enabling full technical validation for circuit design applications.

Frequently Asked Questions (FAQ)

Q: Can MDF7C-20DP-2.54DSA(96) be used as a direct replacement for MDF7C-20DP-2.54DSA?

A: Yes. Both parts are identical in electrical and mechanical specifications across all critical parameters: 20 positions, 0.100" (2.54mm) pitch, 2-row configuration, through-hole mounting, solder termination, and gold contact finish. The substitute part is the active production equivalent.

Q: What is the difference between the main part and the substitute?

A: The primary difference is product status. The main part (MDF7C-20DP-2.54DSA) is obsolete, while the substitute (MDF7C-20DP-2.54DSA(96)) is active. The packaging designation "(96)" indicates the substitute's current production batch or packaging configuration. All functional and electrical parameters remain equivalent.

Q: Are there any compatibility concerns when switching from the main part to the substitute?

A: No compatibility concerns exist. Both parts conform to identical specifications for connector pitch, position count, row spacing, mounting method, and termination type. PCB footprints and mating connector requirements remain unchanged.

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

A: The "(96)" designation indicates the substitute part's packaging configuration or production variant within the MDF7C-20DP-2.54DSA family. This does not affect electrical or mechanical compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both the main part and substitute are RoHS compliant and carry identical moisture sensitivity ratings (MSL 1 - Unlimited), supporting compliance with environmental and regulatory standards.

Q: What is the current availability status of these parts?

A: The main part (MDF7C-20DP-2.54DSA) is obsolete. The substitute part (MDF7C-20DP-2.54DSA(96)) is active and maintains current production availability.
