Key Parameters

Substitute Part Grouping Explanation

Substitution of the MDF7-22DP-2.54DSA(55) is determined by the following critical parameters that must remain constant:

• Connector Series: MDF7 (maintains mechanical and electrical compatibility)
• Number of Positions and Rows: 22 positions in 2-row configuration
• Pitch Specification: 0.100" (2.54mm) mating pitch and row spacing
• Connector Type and Contact Type: Header with male pin contacts
• Mounting Method: Through-hole solder termination
• Electrical Ratings: 3A current rating and 250V voltage rating
• Material and Compliance: Brass contacts with tin finish, PBT insulation, UL94 V-0 flammability rating, RoHS compliant

The MDF7-22DP-2.54DSA(95) qualifies as a direct substitute based on matching all critical parameters. The primary distinction between these parts is the connector style designation (55 vs. 95), which reflects different application contexts rather than fundamental electrical or mechanical incompatibility.

Parameter Comparison

Engineering Selection Recommendations

The MDF7-22DP-2.54DSA(95) is the appropriate substitute for the obsolete MDF7-22DP-2.54DSA(55). Both parts maintain identical electrical and mechanical specifications across all critical parameters. The MDF7-22DP-2.54DSA(95) carries active product status from Hirose Electric Co Ltd, ensuring ongoing availability and manufacturing support. Both parts are RoHS compliant and carry UL94 V-0 flammability certification, meeting current regulatory requirements. The transition from the obsolete (55) variant to the active (95) variant presents no functional or compatibility constraints for board-level integration.

Frequently Asked Questions (FAQ)

Q: Can MDF7-22DP-2.54DSA(95) directly replace MDF7-22DP-2.54DSA(55) in existing designs?

A: Yes. Both parts share identical pitch (0.100" / 2.54mm), position count (22 positions, 2 rows), contact geometry, electrical ratings (3A, 250V), and material specifications. The connector footprint and mating interface are functionally equivalent.

Q: What is the difference between the (55) and (95) designations?

A: The designation suffix reflects different connector style classifications within the MDF7 series. The (95) variant is the active production equivalent of the obsolete (55) variant. Both maintain the same electrical and mechanical interface specifications.

Q: Are there packaging differences between these parts?

A: The MDF7-22DP-2.54DSA(55) is listed without specified packaging, while the MDF7-22DP-2.54DSA(95) is supplied in bag packaging. This difference does not affect connector functionality or board integration.

Q: Do both parts meet current compliance standards?

A: Yes. Both the MDF7-22DP-2.54DSA(55) and MDF7-22DP-2.54DSA(95) are RoHS compliant and carry UL94 V-0 material flammability certification. The (95) variant maintains active status, ensuring compliance with current manufacturing standards.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints during storage or handling.
