Substitute Part Grouping Explanation

Substitution eligibility for the MDF7-23P-2.54DSA(55) is determined by the following critical parameters:

Number of Positions: 23 positions (fixed requirement)
Pitch - Mating: 0.100" (2.54mm) (fixed requirement)
Connector Type: Header (fixed requirement)
Contact Type: Male Pin (fixed requirement)
Mounting Type: Through Hole (fixed requirement)
Termination: Solder (fixed requirement)
Current Rating: 3A (fixed requirement)
Voltage Rating: 250V (fixed requirement)
Operating Temperature Range: -35°C ~ 85°C (fixed requirement)
Contact Material: Brass (fixed requirement)
Insulation Material: Polybutylene Terephthalate (PBT) (fixed requirement)
Material Flammability Rating: UL94 V-0 (fixed requirement)
RoHS Status: RoHS Compliant (fixed requirement)

The MDF7-23P-2.54DSA(95) qualifies as a direct substitute based on matching all critical electrical, mechanical, and compliance parameters. The primary distinction is the connector style designation (Board to Cable/Wire versus Board to Board), which does not affect the core functional compatibility for applications requiring a 23-position, 2.54mm pitch header with the specified electrical and thermal ratings.

Engineering Selection Recommendations

The MDF7-23P-2.54DSA(95) is the qualified substitute for the obsolete MDF7-23P-2.54DSA(55). Both components are manufactured by Hirose Electric Co Ltd within the MDF7 series and maintain identical electrical specifications, mechanical dimensions, and compliance certifications.

The MDF7-23P-2.54DSA(95) carries Active product status, ensuring ongoing availability and manufacturing support. Both parts are RoHS Compliant and carry identical ECCN and HTSUS classifications, supporting regulatory and supply chain continuity.

The voltage rating specification differs in notation (250V versus 250VAC), with the substitute explicitly designating AC voltage. This distinction does not alter the functional equivalence for applications operating within the specified 250V envelope.

Frequently Asked Questions (FAQ)

Q: Can the MDF7-23P-2.54DSA(95) be used as a direct replacement for the MDF7-23P-2.54DSA(55)?

A: Yes. Both components share identical electrical ratings (3A, 250V), mechanical dimensions, contact configuration (23 positions, 2.54mm pitch), and material specifications. The substitute is manufactured by the same supplier and maintains equivalent performance characteristics across the specified operating temperature range (-35°C ~ 85°C).

Q: What is the significance of the different connector style designations (Board to Board versus Board to Cable/Wire)?

A: The style designation reflects the intended mating interface. The MDF7-23P-2.54DSA(55) is specified for Board to Board applications, while the MDF7-23P-2.54DSA(95) is designated for Board to Cable/Wire connections. Both are header connectors with identical pin configurations and electrical properties. Selection depends on the mating connector type required for your application.

Q: Are there packaging differences between these two parts?

A: The MDF7-23P-2.54DSA(55) packaging is not specified in the available data. The MDF7-23P-2.54DSA(95) is supplied in Bag packaging. Confirm packaging requirements with your procurement process.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are RoHS Compliant, carry UL94 V-0 material flammability rating, and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications. Moisture Sensitivity Level is 1 (Unlimited) for both parts.

Q: Why is the MDF7-23P-2.54DSA(55) listed as obsolete?

A: Product status reflects Hirose Electric Co Ltd's current manufacturing and support designation. The MDF7-23P-2.54DSA(95) maintains Active status, ensuring continued availability and supply chain support for new designs and production requirements.
