Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDF7-15P-2.54DSA(55) is determined by the following critical parameters:

• Number of Positions: 15 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)
• RoHS Compliance: Required

The MDF7-15P-2.54DSA(95) qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary distinction between these parts is the connector style designation (Board to Board versus Board to Cable/Wire) and product status (Obsolete versus Active).

Parameter Comparison

Engineering Selection Recommendations

The MDF7-15P-2.54DSA(95) is the direct substitute for the obsolete MDF7-15P-2.54DSA(55). Both components are manufactured by Hirose Electric Co Ltd within the MDF7 series and share identical electrical and mechanical specifications across all critical parameters including pin count, pitch, current rating, voltage rating, and operating temperature range.

The MDF7-15P-2.54DSA(95) maintains active product status with current inventory availability (818 Pcs), ensuring reliable procurement for new designs and production support. Both parts carry RoHS compliance certification and UL94 V-0 flammability rating, meeting regulatory requirements for industrial and commercial applications.

The connector style designation difference (Board to Board versus Board to Cable/Wire) reflects the intended mating interface but does not affect the header's electrical or mechanical performance characteristics. The MDF7-15P-2.54DSA(95) is suitable for direct replacement in applications previously designed with the MDF7-15P-2.54DSA(55).

Frequently Asked Questions (FAQ)

Q: Can the MDF7-15P-2.54DSA(95) be used as a direct replacement for the MDF7-15P-2.54DSA(55)?

A: Yes. Both components share identical electrical specifications (3A current rating, 250V voltage rating), mechanical dimensions (15 positions, 2.54mm pitch, through-hole mounting), contact materials (brass with tin finish), and operating temperature range (-35°C ~ 85°C). The MDF7-15P-2.54DSA(95) is the active production equivalent.

Q: What is the significance of the connector style designation difference?

A: The style designation indicates the intended mating interface. The MDF7-15P-2.54DSA(55) is specified as Board to Board, while the MDF7-15P-2.54DSA(95) is specified as Board to Cable/Wire. This distinction reflects design intent but does not alter the header's physical or electrical characteristics.

Q: Are there packaging differences between these parts?

A: The MDF7-15P-2.54DSA(55) packaging is not specified in available documentation. The MDF7-15P-2.54DSA(95) is supplied in bag packaging. Packaging differences do not affect component functionality or performance.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both the MDF7-15P-2.54DSA(55) and MDF7-15P-2.54DSA(95) are RoHS compliant with UL94 V-0 flammability rating and Moisture Sensitivity Level 1 (Unlimited).

Q: What is the current availability status for these parts?

A: The MDF7-15P-2.54DSA(55) is obsolete with 1051 Pcs listed as new original in stock. The MDF7-15P-2.54DSA(95) is active with 818 Pcs available. For new designs, the MDF7-15P-2.54DSA(95) is recommended due to active product status.
