Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDF7-11P-2.54DSA(55) is determined by the following critical parameters:

• Connector Series: MDF7 (same family)
• Number of Positions: 11 (exact match required)
• Pitch - Mating: 0.100" (2.54mm) (exact match required)
• Contact Type: Male Pin (exact match required)
• Mounting Type: Through Hole (exact match required)
• Current Rating: 3A (exact match required)
• Voltage Rating: 250V (exact match required)
• Operating Temperature Range: -35°C ~ 85°C (exact match required)
• Insulation Material: Polybutylene Terephthalate (PBT) (exact match required)
• Contact Material: Brass (exact match required)
• RoHS Status: RoHS Compliant (exact match required)

The MDF7-11P-2.54DSA(95) qualifies as a direct substitute based on matching all critical electrical and mechanical parameters within the MDF7 series.

Parameter Comparison

Engineering Selection Recommendations

The MDF7-11P-2.54DSA(95) is the qualified substitute for the obsolete MDF7-11P-2.54DSA(55). Both parts maintain identical electrical specifications (3A, 250V), mechanical dimensions, and material composition. The primary distinction is product status: the MDF7-11P-2.54DSA(95) is currently active and available in production quantities, while the original part is obsolete.

Both parts carry RoHS compliance certification and UL94 V-0 flammability rating, meeting the same regulatory and safety requirements. The MDF7-11P-2.54DSA(95) is suitable for direct replacement in applications requiring the MDF7 series 11-position header with 2.54mm pitch configuration.

Frequently Asked Questions (FAQ)

Q: Can the MDF7-11P-2.54DSA(95) be used as a direct replacement for the MDF7-11P-2.54DSA(55)?

A: Yes. Both parts share identical electrical ratings (3A, 250V), mechanical dimensions, contact configuration, and material specifications. The MDF7-11P-2.54DSA(95) is the active equivalent of the obsolete MDF7-11P-2.54DSA(55).

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

A: The suffix designation (55 versus 95) indicates packaging and product status. The MDF7-11P-2.54DSA(55) is obsolete, while the MDF7-11P-2.54DSA(95) is active production. All functional and electrical parameters remain identical.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. Both parts are from the same MDF7 series with matching pitch (2.54mm), position count (11), contact type (male pin), and mounting method (through hole). PCB footprints and mating interfaces are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the MDF7-11P-2.54DSA(55) and MDF7-11P-2.54DSA(95) are RoHS compliant and carry UL94 V-0 flammability certification. Moisture sensitivity level is 1 (Unlimited) for both parts.

Q: What is the packaging difference between these parts?

A: The MDF7-11P-2.54DSA(55) packaging is not specified in available data. The MDF7-11P-2.54DSA(95) is supplied in bag packaging. This distinction does not affect functional performance or electrical characteristics.
