Key Parameters

Substitute Part Grouping Explanation

The MDF7-22P-2.54DS(95) qualifies as a direct substitute based on the following critical parameters:

• Identical series designation (MDF7)
• Identical number of positions (22)
• Identical mating pitch (0.100" / 2.54mm)
• Identical connector type (Header, Male Pin)
• Identical mounting configuration (Through Hole, Right Angle)
• Identical electrical ratings (3A current, 250V voltage)
• Identical operating temperature range (-35°C ~ 85°C)
• Identical material specifications (Brass contacts, PBT insulation)
• Identical contact finish (Tin plating)
• Identical compliance certifications (RoHS Compliant, UL94 V-0)

The primary distinction is product status: MDF7-22P-2.54DS(55) is obsolete, while MDF7-22P-2.54DS(95) maintains active status with current manufacturing support.

Frequently Asked Questions (FAQ)

Q: Are MDF7-22P-2.54DS(55) and MDF7-22P-2.54DS(95) electrically interchangeable?

A: Yes. Both parts share identical electrical ratings (3A current, 250V voltage), operating temperature range (-35°C ~ 85°C), and contact specifications. They are direct electrical equivalents.

Q: What is the mechanical compatibility between these parts?

A: Both parts are mechanically compatible. They feature identical 22-position, 0.100" (2.54mm) pitch configurations with through-hole, right-angle mounting. PCB footprints and mating interface dimensions are equivalent.

Q: Why does the voltage rating show different notation (250V vs 250VAC)?

A: Both specifications indicate 250V AC rating. The notation difference reflects documentation variations between obsolete and active product revisions but represents identical electrical capability.

Q: What is the significance of the product status difference?

A: MDF7-22P-2.54DS(55) is obsolete and no longer manufactured. MDF7-22P-2.54DS(95) is active, ensuring ongoing availability, technical support, and compliance with current manufacturing standards.

Q: Are there packaging differences between these parts?

A: MDF7-22P-2.54DS(95) is supplied in bag packaging. Packaging format does not affect electrical or mechanical performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS Compliant with UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity level.
