Substitute Part Grouping Explanation

Substitution eligibility for the MDF7-26DP-2.54DSA(55) is determined by strict equivalence across the following critical parameters:

• Number of Positions: 26
• Pitch - Mating: 0.100" (2.54mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Current Rating: 3A
• Voltage Rating: 250V
• Operating Temperature Range: -35°C ~ 85°C
• Contact Material: Brass
• Insulation Material: Polybutylene Terephthalate (PBT)
• Material Flammability Rating: UL94 V-0
• RoHS Compliance: RoHS Compliant

The MDF7-26DP-2.54DSA(95) meets all substitution criteria as an active product within the same MDF7 series, maintaining identical electrical and mechanical specifications while differing only in application style and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The MDF7-26DP-2.54DSA(95) is the direct substitute for the obsolete MDF7-26DP-2.54DSA(55). Both components maintain identical electrical ratings, mechanical dimensions, and material specifications. The substitute part carries active product status with current manufacturing support from Hirose Electric Co Ltd, ensuring long-term availability and supply chain continuity.

Both parts satisfy RoHS compliance requirements and UL94 V-0 flammability certification. The primary distinction lies in application designation: the original part targets board-to-board configurations, while the substitute is designated for board-to-cable/wire applications. This difference reflects connector interface design rather than electrical or thermal performance characteristics.

Current inventory availability of 952 pieces for the MDF7-26DP-2.54DSA(95) supports immediate procurement requirements for designs requiring this connector specification.

Frequently Asked Questions (FAQ)

Q: Can the MDF7-26DP-2.54DSA(95) directly replace the MDF7-26DP-2.54DSA(55) in existing designs?

A: Yes. Both parts maintain identical pin count (26 positions), pitch spacing (0.100" / 2.54mm), row configuration (2 rows), electrical ratings (3A / 250V), and operating temperature range (-35°C ~ 85°C). The substitute is electrically and mechanically equivalent.

Q: What is the significance of the application style difference (Board to Board vs. Board to Cable/Wire)?

A: Application style designation indicates the intended mating interface design. The electrical and mechanical specifications remain identical. Component selection should be based on the specific mating connector or cable assembly requirements of the application.

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

A: No. Both parts are RoHS compliant and carry UL94 V-0 flammability certification. Moisture sensitivity level is identical at MSL 1 (Unlimited).

Q: What is the packaging difference, and does it affect component performance?

A: The original part packaging is not specified, while the substitute is supplied in bag packaging. Packaging format does not affect electrical or mechanical performance; it addresses logistics and handling requirements only.

Q: Why is the original part classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production. The MDF7-26DP-2.54DSA(95) remains in active production status, providing a current alternative for ongoing design support and new procurement.
