Key Parameters

Substitute Part Grouping Explanation

The MDF7-17P-2.54DS(96) qualifies as a direct substitute based on the following critical parameters:

• Connector Series: Both parts belong to the MDF7 series, ensuring mechanical and electrical compatibility
• Position Count: Identical 17-position configuration
• Mating Pitch: Both use 0.100" (2.54mm) pitch spacing
• Contact Type: Both feature male pin contacts
• Mounting Configuration: Both are through-hole, right-angle mounted
• Electrical Ratings: Both support 3A current and 250V voltage operation
• Operating Temperature Range: Identical -35°C ~ 85°C specification
• Material Compliance: Both are RoHS compliant with UL94 V-0 flammability rating
• Contact Material & Finish: Both use brass contacts with gold mating surface finish

The primary difference is application style: MDF7-17P-2.54DS(56) is configured for board-to-board connections, while MDF7-17P-2.54DS(96) is configured for board-to-cable/wire connections. Both maintain identical electrical and mechanical interface specifications.

Parameter Comparison

Engineering Selection Recommendations

The MDF7-17P-2.54DS(96) is the appropriate substitute for the obsolete MDF7-17P-2.54DS(56) based on the following factors:

• Product Status: The substitute maintains active product status, ensuring continued availability and manufacturing support
• Regulatory Compliance: Both parts maintain identical RoHS compliance and UL94 V-0 flammability certification
• Electrical Equivalence: Identical current (3A) and voltage (250V/250VAC) ratings ensure direct electrical compatibility
• Mechanical Compatibility: Matching pitch, position count, contact geometry, and mounting configuration enable direct mechanical substitution
• Thermal Performance: Identical operating temperature range (-35°C ~ 85°C) maintains thermal design margins

Selection of the MDF7-17P-2.54DS(96) eliminates obsolescence risk while preserving all critical electrical and mechanical specifications required for system operation.

Frequently Asked Questions (FAQ)

Q: Can MDF7-17P-2.54DS(96) directly replace MDF7-17P-2.54DS(56) in existing designs?

A: Yes. Both parts share identical electrical ratings (3A, 250V), operating temperature range (-35°C ~ 85°C), pitch (0.100"/2.54mm), position count (17), and contact configuration. The primary design difference is application style (board-to-cable versus board-to-board), which does not affect electrical or mechanical interface compatibility.

Q: What is the significance of the different application styles?

A: MDF7-17P-2.54DS(56) is designed for board-to-board interconnection, while MDF7-17P-2.54DS(96) is designed for board-to-cable/wire interconnection. This distinction reflects the intended mating connector type but does not affect the header's electrical or mechanical specifications.

Q: Are there packaging differences between these parts?

A: MDF7-17P-2.54DS(56) packaging is not specified in available data. MDF7-17P-2.54DS(96) is supplied in bag packaging. Packaging differences do not affect component functionality or electrical performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS compliant and carry UL94 V-0 flammability certification. Both have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements.

Q: What is the contact mating length difference between these parts?

A: MDF7-17P-2.54DS(56) has a contact mating length of 0.292" (7.42mm), while MDF7-17P-2.54DS(96) has 0.293" (7.45mm). This 0.001" (0.03mm) difference is within standard manufacturing tolerance and does not affect mating compatibility.
