Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDF7B-15P-2.54DSA(55) is determined by the following critical parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 15
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Current Rating: 3A
• Voltage Rating: 250V
• Operating Temperature Range: -35°C ~ 85°C
• Contact Material: Brass
• Insulation Material: Polybutylene Terephthalate (PBT)
• RoHS Compliance: Required

The MDF7B-15P-2.54DSA(95) qualifies as a direct substitute, maintaining identical electrical and mechanical specifications across all critical parameters. The primary distinction lies in packaging format (Bulk versus Bag) and product status (Obsolete versus Active).

Parameter Comparison

Engineering Selection Recommendations

The MDF7B-15P-2.54DSA(95) is the direct substitute for the obsolete MDF7B-15P-2.54DSA(55). Both parts maintain identical electrical performance specifications, mechanical dimensions, and material composition. The substitute part carries Active product status, ensuring continued availability and manufacturing support from Hirose Electric Co Ltd. Both parts satisfy RoHS compliance requirements and carry UL94 V-0 flammability certification. The packaging difference (Bulk to Bag) does not affect functional compatibility or performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can MDF7B-15P-2.54DSA(95) be used as a direct replacement for MDF7B-15P-2.54DSA(55)?

A: Yes. Both parts share identical electrical ratings (3A, 250V), mechanical specifications (15 positions, 0.100" pitch, through-hole mounting), contact materials (brass with tin finish), and insulation properties (PBT, UL94 V-0). The substitute maintains full functional compatibility.

Q: What is the difference between the two part numbers?

A: The primary differences are packaging format and product status. MDF7B-15P-2.54DSA(55) is supplied in Bulk packaging with Obsolete status. MDF7B-15P-2.54DSA(95) is supplied in Bag packaging with Active status. These differences do not affect connector performance or PCB integration.

Q: Are there any dimensional differences between these parts?

A: Overall contact length differs by 0.01mm (0.867" versus 0.866"), which is within manufacturing tolerance and does not affect functional compatibility or mating performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS Compliant, carry UL94 V-0 flammability rating, and maintain identical operating temperature ranges (-35°C ~ 85°C) and moisture sensitivity levels (MSL 1).

Q: Why should I transition from the obsolete part to the active substitute?

A: The obsolete status of MDF7B-15P-2.54DSA(55) indicates discontinued manufacturing. Transitioning to MDF7B-15P-2.54DSA(95) ensures long-term supply chain continuity, ongoing technical support, and access to current inventory from Hirose Electric Co Ltd.
