Parameter Comparison

Engineering Selection Recommendations

The KMBX-SMT-5S-S-30TR is the qualified substitute for the obsolete UX60-MB-5S8(21). Selection is based on:

Product Status: The substitute part is in active production, ensuring availability for new designs and legacy system support. The original part is obsolete and no longer manufactured.

Compliance & Certifications: Both parts meet UL94 V-0 flammability requirements and carry identical moisture sensitivity ratings (MSL 1). The substitute part is ROHS3 compliant and REACH unaffected, meeting current regulatory standards.

Electrical & Mechanical Compatibility: The substitute maintains identical USB 2.0 specifications, contact configuration, current rating, mating cycle rating, and mounting characteristics. The higher voltage rating (30VAC vs. 5VAC) and extended operating temperature range (-55°C to 85°C vs. -30°C to 75°C) of the substitute part provide additional design margin without compromising compatibility.

Supply Chain Continuity: The substitute part is available in standard Tape & Reel packaging with confirmed inventory, supporting both prototype and production-volume requirements.

Frequently Asked Questions (FAQ)

Q: Can the KMBX-SMT-5S-S-30TR directly replace the UX60-MB-5S8(21) in existing designs?

A: Yes. Both connectors share identical USB 2.0 mini B receptacle specifications, 5-position contact configuration, gold-plated termination, and horizontal surface mount/through-hole mounting. Mechanical and electrical compatibility is maintained across all functional parameters.

Q: What are the key differences between these two parts?

A: The primary differences are product status and operating specifications. The UX60-MB-5S8(21) is obsolete; the KMBX-SMT-5S-S-30TR is in active production. The substitute part has a higher rated voltage (30VAC vs. 5VAC) and wider operating temperature range (-55°C to 85°C vs. -30°C to 75°C). These differences favor the substitute part for new designs and long-term availability.

Q: Are there packaging considerations when switching to the KMBX-SMT-5S-S-30TR?

A: The substitute part is supplied in Tape & Reel (TR) packaging, which is standard for surface mount production. The original part packaging information was not specified. Tape & Reel format is compatible with automated assembly equipment and is suitable for both prototype and high-volume manufacturing.

Q: Do both parts meet the same regulatory and compliance standards?

A: Both parts meet UL94 V-0 flammability requirements and carry MSL 1 (unlimited moisture sensitivity). The substitute part additionally carries ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements.

Q: Is the higher voltage rating of the substitute part a concern for 5VAC applications?

A: No. The 30VAC rating of the KMBX-SMT-5S-S-30TR is a maximum specification. It is fully compatible with 5VAC applications and provides additional design margin. Higher voltage ratings do not create compatibility issues in lower-voltage circuits.
