Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDF7-9P-2.54DS(56) is determined by the following critical parameters:

• Pitch and Position Count: 0.100" (2.54mm) pitch with 9 positions
• Connector Type and Contact Configuration: Header with male pins
• Mounting Orientation: Through hole, right-angle mounting
• Electrical Ratings: 3A current and 250V voltage minimum
• Material and Compliance: PBT insulation, UL94 V-0 flammability rating, RoHS compliance
• Contact Finish: Gold-plated mating surface
• Operating Temperature Range: -35°C ~ 85°C

The MDF7-9P-2.54DS(96) qualifies as a direct substitute based on matching all critical parameters within the allowed tolerance specifications for this connector category.

Parameter Comparison

Engineering Selection Recommendations

The MDF7-9P-2.54DS(96) is the qualified substitute for the obsolete MDF7-9P-2.54DS(56). Both parts maintain identical electrical specifications, mechanical dimensions, and material certifications. The primary distinction is product status: the MDF7-9P-2.54DS(56) is obsolete, while the MDF7-9P-2.54DS(96) maintains active production status with current inventory availability.

Both parts satisfy RoHS compliance requirements and UL94 V-0 flammability certification. The voltage rating specification differs slightly in notation (250V versus 250VAC), reflecting standard documentation practices for the same electrical performance class. Contact length specifications show negligible variation (0.293" versus 0.292" mating contact length), which falls within standard manufacturing tolerances for this connector category.

Frequently Asked Questions (FAQ)

Q: Can MDF7-9P-2.54DS(96) be used as a direct replacement for MDF7-9P-2.54DS(56)?

A: Yes. Both parts share identical pitch (0.100"/2.54mm), position count (9), mounting type (through-hole right-angle), electrical ratings (3A/250V), and material specifications. The MDF7-9P-2.54DS(96) is the active production equivalent.

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

A: The primary difference is product lifecycle status. The MDF7-9P-2.54DS(56) is obsolete, while MDF7-9P-2.54DS(96) is in active production. Both are functionally equivalent for board-to-board connector applications within the specified electrical and thermal parameters.

Q: Are there packaging differences between these parts?

A: The MDF7-9P-2.54DS(56) packaging is not specified in available documentation. The MDF7-9P-2.54DS(96) is supplied in bag packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Do these connectors support board-to-cable applications?

A: The MDF7-9P-2.54DS(56) is specified for board-to-board style applications. The MDF7-9P-2.54DS(96) is specified for board-to-cable/wire style applications. While both use identical connector geometry and electrical specifications, the intended mating interface differs. Verify mating connector compatibility for your specific application.

Q: What are the compliance certifications for these parts?

A: Both parts are RoHS compliant and carry UL94 V-0 flammability certification. Moisture sensitivity level is rated at MSL 1 (unlimited), indicating no special moisture handling requirements during storage or assembly.
