Substitute Part Grouping Explanation
Substitution eligibility for the MDF7P-12DP-2.54DSA(55) is determined by strict equivalence across the following critical parameters:
- Connector type (Header)
- Contact type (Male Pin)
- Number of positions (12) and rows (2)
- Pitch configuration (0.100" / 2.54mm mating pitch and row spacing)
- Mounting type (Through Hole)
- Termination method (Solder)
- Electrical ratings (3A current, 250V voltage minimum)
- Operating temperature range (-35°C ~ 85°C)
- Material compliance (RoHS Compliant, UL94 V-0)
The MDF7P-12DP-2.54DSA(95) meets all substitution criteria as a direct equivalent within the MDF7 series, with the primary distinction being product status transition from obsolete to active availability.

Engineering Selection Recommendations
The MDF7P-12DP-2.54DSA(95) is the direct substitute for the obsolete MDF7P-12DP-2.54DSA(55). Both parts maintain identical electrical and mechanical specifications within the MDF7 series, with full compliance to RoHS requirements and UL94 V-0 flammability standards. The primary advantage of the MDF7P-12DP-2.54DSA(95) is active product status, ensuring ongoing availability and supply chain continuity. Selection of the active variant eliminates obsolescence risk while maintaining complete functional and dimensional compatibility.
Frequently Asked Questions (FAQ)
Q: Are the MDF7P-12DP-2.54DSA(55) and MDF7P-12DP-2.54DSA(95) mechanically interchangeable?
A: Yes. Both connectors share identical pitch (0.100" / 2.54mm), contact geometry, mounting configuration, and overall dimensions. Through-hole PCB footprints designed for either part are fully compatible.
Q: What is the difference between the two part numbers?
A: The suffix designation (55 versus 95) reflects packaging and product lifecycle status. The MDF7P-12DP-2.54DSA(55) is obsolete, while the MDF7P-12DP-2.54DSA(95) maintains active status with current manufacturing and distribution support.
Q: Can I use the MDF7P-12DP-2.54DSA(95) in designs originally specified for the MDF7P-12DP-2.54DSA(55)?
A: Yes. Electrical ratings (3A, 250V), operating temperature range (-35°C ~ 85°C), and all mechanical parameters are identical. Direct substitution is appropriate for new production and design updates.
Q: Are both parts RoHS compliant?
A: Yes. Both the MDF7P-12DP-2.54DSA(55) and MDF7P-12DP-2.54DSA(95) are RoHS Compliant with UL94 V-0 flammability certification.
Q: What is the moisture sensitivity level for these connectors?
A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
