Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDF7P-19P-2.54DSA(55) is determined by the following critical parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 19
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Current Rating: 3A
• Voltage Rating: 250V
• Operating Temperature Range: -35°C ~ 85°C
• Material Flammability Rating: UL94 V-0
• Contact Material: Brass
• Insulation Material: Polybutylene Terephthalate (PBT)
• RoHS Compliance: Required

The substitute part MDF7P-19P-2.54DSA(95) maintains all critical electrical and mechanical parameters required for direct substitution. The primary distinction is product status: the substitute carries active status, ensuring continued availability and manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The MDF7P-19P-2.54DSA(95) is the direct substitute for the obsolete MDF7P-19P-2.54DSA(55). Both parts are manufactured by Hirose Electric Co Ltd within the MDF7 series and maintain identical electrical and mechanical specifications. The substitute part carries active product status, ensuring manufacturing continuity and supply chain availability.

Both parts satisfy RoHS compliance requirements and carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8536.69.4040). The UL94 V-0 flammability rating is maintained across both variants, meeting safety standards for the specified operating temperature range of -35°C to 85°C.

Selection of the active substitute part eliminates obsolescence risk while preserving full functional and mechanical compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can MDF7P-19P-2.54DSA(95) be used as a direct replacement for MDF7P-19P-2.54DSA(55)?

A: Yes. Both parts share identical electrical ratings (3A, 250V), mechanical dimensions, contact configuration (19 positions, 0.100" pitch), and material specifications. The substitute carries active product status, providing continued manufacturing support.

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

A: The suffix designation (55 versus 95) indicates packaging and product lifecycle status. MDF7P-19P-2.54DSA(55) is obsolete, while MDF7P-19P-2.54DSA(95) is active. The electrical and mechanical specifications remain identical.

Q: Are there any compatibility concerns when switching from the obsolete to the active part?

A: No compatibility concerns exist. Both parts are manufactured to the same specifications and are mechanically and electrically interchangeable. PCB footprints, mating connector requirements, and electrical performance remain unchanged.

Q: What packaging is provided with each part?

A: MDF7P-19P-2.54DSA(55) packaging is not specified in available documentation. MDF7P-19P-2.54DSA(95) is supplied in bag packaging.

Q: Are both parts RoHS compliant?

A: Yes. Both MDF7P-19P-2.54DSA(55) and MDF7P-19P-2.54DSA(95) are RoHS compliant with identical moisture sensitivity levels (MSL 1 - Unlimited).
