Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDF7-14P-2.54DSA(55) is determined by the following critical parameters:

• Connector series and base product number (MDF7)
• Number of positions (14)
• Pitch spacing (0.100" / 2.54mm)
• Contact type (Male Pin)
• Mounting type (Through Hole)
• Electrical ratings (3A current, 250V voltage)
• Operating temperature range (-35°C ~ 85°C)
• Material compliance (RoHS Compliant, UL94 V-0)

The MDF7-14P-2.54DSA(95) qualifies as a direct substitute based on matching all critical electrical, mechanical, and compliance parameters. The primary distinction between these parts is the connector style designation (board-to-board versus board-to-cable/wire interface) and packaging format, which do not affect the core mating interface or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

• Identical mechanical interface (14 positions, 2.54mm pitch, through-hole mounting)
• Equivalent material composition and flammability certification (UL94 V-0)
• RoHS compliance maintained
• Moisture sensitivity level unchanged (MSL 1)
• Active product status enabling procurement and technical support

Frequently Asked Questions (FAQ)

Q: Can the MDF7-14P-2.54DSA(95) be used as a direct replacement for the MDF7-14P-2.54DSA(55)?

A: Yes. Both parts share identical electrical ratings, mechanical dimensions, contact configurations, and material specifications. The mating interface and pin layout are equivalent, allowing direct substitution in applications designed for the original part.

Q: What is the difference between the board-to-board and board-to-cable/wire designations?

A: The style designation indicates the intended mating interface. The MDF7-14P-2.54DSA(55) is specified for board-to-board connections, while the MDF7-14P-2.54DSA(95) is specified for board-to-cable/wire connections. Both use identical header pin configurations and are compatible with standard 2.54mm pitch receptacles.

Q: Does the packaging difference affect compatibility?

A: No. Packaging format (bag versus other formats) does not affect the electrical or mechanical performance of the connector. The component itself remains unchanged.

Q: Why is the original part listed as obsolete?

A: Product status reflects manufacturer lifecycle decisions. The MDF7-14P-2.54DSA(95) maintains active status, providing a current alternative for new designs and ongoing production requirements.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical RoHS compliance, UL94 V-0 flammability rating, and moisture sensitivity level (MSL 1). Electrical and thermal specifications are equivalent.
