Substitute Part Grouping Explanation

Substitution of the MDF7-30DP-2.54DSA(55) is determined by the following critical parameters:

  • Connector geometry: 30 positions, 2 rows, 0.100" (2.54mm) pitch and row spacing
  • Electrical ratings: 3A current capacity, 250V voltage rating
  • Mechanical interface: Through-hole mounting, male pin contact type, solder termination
  • Material and compliance: Brass contacts with tin finish, PBT insulation, UL94 V-0 flammability rating, RoHS compliance

The MDF7-30DP-2.54DSA(95) qualifies as a direct substitute based on matching all critical parameters. The primary distinction is the connector style designation, which reflects packaging and application context rather than functional electrical or mechanical incompatibility.

Engineering Selection Recommendations

The MDF7-30DP-2.54DSA(95) is the direct substitute for the obsolete MDF7-30DP-2.54DSA(55). Both components are manufactured by Hirose Electric Co Ltd within the MDF7 series and maintain identical electrical and mechanical specifications across all critical parameters.

Selection of the MDF7-30DP-2.54DSA(95) is supported by:

  • Active product status, ensuring ongoing availability and supply chain continuity
  • Full RoHS compliance matching the original component
  • UL94 V-0 flammability certification maintained
  • Identical electrical ratings (3A, 250V) and operating temperature range (-35°C ~ 85°C)
  • Matching mechanical interface specifications including pitch, row spacing, contact geometry, and termination method

Frequently Asked Questions (FAQ)

Q: Can the MDF7-30DP-2.54DSA(95) be used as a direct replacement for the MDF7-30DP-2.54DSA(55)?

A: Yes. Both components share identical connector geometry (30 positions, 2 rows, 0.100" pitch), electrical ratings (3A, 250V), contact specifications (brass with tin finish), and material properties (PBT insulation, UL94 V-0). The primary difference is product status: the (55) variant is obsolete while the (95) variant is active.

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

A: The designation suffix reflects packaging and application context. The (55) variant is specified for board-to-board applications, while the (95) variant is specified for board-to-cable/wire applications. Both maintain the same core connector specifications and are mechanically and electrically interchangeable.

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

A: No. Both components are RoHS compliant, carry UL94 V-0 flammability ratings, and operate across the identical temperature range (-35°C ~ 85°C). Moisture sensitivity level is 1 (Unlimited) for both variants.

Q: What is the current inventory status?

A: The MDF7-30DP-2.54DSA(55) has 943 pieces in stock as new original inventory. The MDF7-30DP-2.54DSA(95) has 925 pieces in stock as new original inventory.

Q: Are there any electrical parameter differences I should consider?

A: The voltage rating specification differs slightly in notation: the (55) variant is rated 250V while the (95) variant is rated 250VAC. Both specifications indicate the same voltage capacity for this connector type.
