Engineering Selection Recommendations

The Hirose Electric Co Ltd ZX40-B-5S-UNIT(31) is the qualified substitute for the obsolete TE Connectivity AMP 1939054-3. Selection is based on the following engineering criteria:

Product Status and Availability: The TE Connectivity AMP 1939054-3 is classified as obsolete, creating supply chain risk for new production and field replacements. The Hirose Electric ZX40-B-5S-UNIT(31) maintains active product status, ensuring continued availability and manufacturer support.

Electrical and Mechanical Equivalence: Both connectors meet identical specifications for USB 2.0 Micro B plug configuration with 5 contacts, solder termination, and free hanging (in-line) mounting. Operating temperature ranges, voltage ratings, mating cycle specifications, and contact finishes are equivalent across both parts.

Regulatory Compliance: Both parts are ROHS3 compliant and meet the same electrical classification standards (ECCN: EAR99, HTSUS: 8536.69.8000). The Hirose part carries UL94 V-0 material flammability certification and REACH unaffected status, providing additional compliance documentation.

Moisture Sensitivity: The TE Connectivity part carries MSL 1 (Unlimited) rating. The Hirose part is classified as Not Applicable for MSL, indicating superior moisture handling characteristics suitable for extended storage and field deployment.

Frequently Asked Questions (FAQ)

Q: Can the Hirose Electric ZX40-B-5S-UNIT(31) be used as a direct replacement for the TE Connectivity AMP 1939054-3?

A: Yes. Both connectors are electrically and mechanically equivalent USB 2.0 Micro B plug connectors with 5 contacts, solder termination, and identical operating specifications. The Hirose part is an active product with equivalent compliance certifications.

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

A: The primary differences are product status and packaging. The TE Connectivity part is obsolete, while the Hirose part is active. The Hirose part is supplied in tray packaging. The Hirose part includes UL94 V-0 material flammability certification and REACH unaffected status. Voltage rating specification differs slightly (30V versus 30VAC), but both are functionally equivalent for USB 2.0 applications.

Q: Are there any compatibility concerns when substituting the Hirose part for the TE Connectivity part?

A: No compatibility concerns exist. Both connectors share identical connector type, contact count, gender, mounting method, termination type, operating temperature range, voltage rating, mating cycle specification, contact finish, and shell material. Electrical and mechanical interfaces are fully compatible.

Q: What is the current rating difference between these connectors?

A: The TE Connectivity part specifies multiple current ratings (0.5A, 1A, 1.8A), while the Hirose part specifies 1A per contact. For applications requiring 1A operation, both parts are equivalent. Applications requiring 0.5A or 1.8A operation should reference the specific current requirements of the USB 2.0 Micro B interface specification.

Q: Does the packaging difference affect connector performance?

A: No. Packaging (tray versus unspecified) affects handling, storage, and logistics only. Connector electrical and mechanical performance is independent of packaging format.

Q: Are both connectors suitable for high-temperature applications?

A: Yes. Both connectors operate across the identical temperature range of -30°C to 85°C, meeting standard industrial and consumer electronics thermal requirements.

Q: What is the significance of the Hirose part's UL94 V-0 certification?

A: UL94 V-0 certification indicates the connector shell material meets the highest flammability resistance standard. This provides additional safety documentation for applications subject to flammability requirements or safety-critical environments.
