Parameter Comparison

Engineering Selection Recommendations

The MXR-8PA-6PB(71) serves as the direct substitute for the obsolete MXR-8PA-6PB. Key considerations for component selection:

Product Status: The original part is classified as obsolete, while the substitute is designated Last Time Buy. This status transition indicates limited future availability of the original part number, making the substitute the appropriate choice for new procurement and system redesigns.

Compliance Improvement: The substitute part achieves RoHS compliance, whereas the original part is RoHS non-compliant. Systems requiring RoHS-compliant components should transition to MXR-8PA-6PB(71).

Enhanced Specifications: The substitute part provides documented electrical ratings (2A current, 100VAC/140VDC voltage) and operating temperature range (-25°C ~ 85°C), which are not specified for the original part. The gold contact finish on the substitute offers improved corrosion resistance compared to the unspecified contact finish of the original.

Mechanical Compatibility: Both parts maintain identical mechanical interfaces, shell dimensions, and fastening characteristics, ensuring direct form-fit-function replacement in existing assemblies.

Frequently Asked Questions (FAQ)

Q: Can MXR-8PA-6PB(71) be used as a direct replacement for MXR-8PA-6PB?

A: Yes. Both parts share identical connector type, pin count, shell size, termination method, fastening type, and orientation. The mechanical and electrical interfaces are fully compatible.

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

A: The primary differences are product status, RoHS compliance, and documented electrical specifications. MXR-8PA-6PB(71) includes gold contact finish, specified current and voltage ratings, and operating temperature range. The original part lacks these documented specifications.

Q: Why is the original part obsolete?

A: The MXR-8PA-6PB is marked obsolete, indicating it has been discontinued by the manufacturer. The substitute MXR-8PA-6PB(71) represents the current production equivalent within the MXR series.

Q: Are there packaging differences between these parts?

A: The original part packaging is not specified. The substitute is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Does the gold contact finish on MXR-8PA-6PB(71) affect compatibility?

A: No. The gold contact finish is an enhancement that improves corrosion resistance and contact reliability. It does not affect mechanical or electrical compatibility with mating connectors designed for the MXR-8PA series.

Q: What is the MSL rating for these connectors?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
