Parameter Comparison

Engineering Selection Recommendations

The MDF7B-13P-2.54DSA(95) is the direct active substitute for the obsolete MDF7B-13P-2.54DSA(55). Both parts maintain identical electrical specifications (3A, 250V), mechanical dimensions, and material certifications. The substitute part carries active product status with current manufacturing availability, whereas the original part is classified as obsolete. Both parts comply with RoHS requirements and UL94 V-0 flammability standards. Selection of the active substitute ensures continued supply chain access and manufacturing support.

Frequently Asked Questions (FAQ)

Q: What determines compatibility between MDF7B-13P-2.54DSA(55) and MDF7B-13P-2.54DSA(95)?

A: Compatibility is established through matching connector type, contact configuration, position count, pitch specification, mounting method, electrical ratings, and material properties. Both parts are 13-position headers with 0.100" pitch, through-hole mounting, 3A current capacity, and 250V voltage rating.

Q: Are there dimensional differences between these parts?

A: Overall contact length differs by 0.01" (0.01mm), with the main part at 0.867" (22.01mm) and the substitute at 0.866" (22.00mm). This variance is within standard manufacturing tolerance and does not affect functional compatibility.

Q: What is the significance of the product status difference?

A: The main part is classified as obsolete, indicating discontinued manufacturing. The substitute part maintains active status with current production and inventory availability, ensuring long-term supply chain reliability.

Q: Are packaging differences relevant to substitution?

A: The main part packaging is unspecified, while the substitute is packaged in bags. Packaging does not affect electrical or mechanical performance and is determined by distribution and handling requirements.
