Engineering Selection Recommendations

Hirose Direct Equivalents (Recommended for Pin-Compatible Replacement):

UX60SC-MB-5ST(80) and UX60SC-MB-5ST(85) are the primary Hirose alternatives. Both maintain the same connector geometry, contact configuration, and solder termination as the UX60SA-MB-5ST. UX60SC-MB-5ST(80) offers the highest inventory availability (32,714 pcs) and is compliant with ROHS3. UX60SC-MB-5ST(85) maintains active product status. Both support 5000 mating cycles and operate across the required -30°C to 75°C temperature range. The voltage rating increase to 30VAC provides additional design margin without affecting USB 2.0 signal integrity.

UX60-MB-5ST(70) is an active Hirose variant with confirmed 1A current rating and 5000 mating cycles. This part includes a board guide feature and maintains full parameter compatibility with the original specification.

TE Connectivity Alternatives (Cross-Manufacturer Substitution):

The 1-1734035 series (1-1734035-2 and 1-1734035-3) and 2-1734035-2 from TE Connectivity AMP Connectors provide parametric equivalence with extended operating temperature range (-40°C to 85°C). All three parts are active products with ROHS3 compliance (1-1734035-2 and 2-1734035-2) or RoHS compliance (1-1734035-3). Steel shell material (SUS304) provides enhanced durability compared to phosphor bronze. These parts support 1A current, 30VAC voltage rating, and 5000 mating cycles.

GCT Alternative (Extended Temperature Range):

USB2066-05-RBHM-15-STB-00-00-A from GCT meets all primary substitution criteria with extended operating temperature (-50°C to 85°C) and ROHS3 compliance. Brass shell material and 30VDC rating provide alternative material composition while maintaining electrical compatibility.

Product Status Considerations:

For new designs, prioritize active-status parts: UX60-MB-5ST(70), UX60SC-MB-5ST(85), 1-1734035-2, 1-1734035-3, 2-1734035-2, and USB2066-05-RBHM-15-STB-00-00-A. For legacy production support, UX60SC-MB-5ST(80) offers substantial inventory despite Last Time Buy status.

Frequently Asked Questions (FAQ)

Q: Can UX60SC-MB-5ST(80) directly replace UX60SA-MB-5ST in existing designs?

A: Yes. Both connectors maintain identical USB 2.0 mini B receptacle geometry, 5-position contact configuration, surface mount right-angle mounting, and solder termination. The voltage rating increase from 5VAC to 30VAC does not affect USB 2.0 signal specifications. PCB footprints are compatible.

Q: What is the difference between UX60SA-MB-5ST and UX60SC-MB-5ST variants?

A: The primary difference is shell material composition. UX60SA uses phosphor bronze; UX60SC uses copper alloy. Both maintain identical electrical performance, contact count, and mounting characteristics. The "C" designation in UX60SC indicates the copper alloy variant.

Q: Are TE Connectivity 1-1734035 series connectors mechanically compatible with Hirose UX60 series?

A: Yes. Both manufacturers' USB 2.0 mini B receptacle connectors conform to the same USB 2.0 specification for mechanical and electrical interface. PCB footprints are standardized across compliant manufacturers. The TE Connectivity parts feature steel shell material instead of phosphor bronze or copper alloy, providing enhanced mechanical durability.

Q: What packaging options are available for production quantities?

A: Hirose UX60SC-MB-5ST(80) is available in Cut Tape and Digi-Reel packaging with 32,714 pcs inventory. TE Connectivity 2-1734035-2 is available in Tape & Reel with 3,969 pcs. GCT USB2066-05-RBHM-15-STB-00-00-A is available in Tape & Reel with 2,456 pcs. Packaging selection depends on assembly line equipment compatibility and order quantity requirements.

Q: Does the extended operating temperature range of TE Connectivity parts affect USB 2.0 compliance?

A: No. The extended temperature range (-40°C to 85°C) does not alter USB 2.0 electrical specifications or signal integrity. This extended range provides additional design margin for applications operating outside the original -30°C to 75°C specification.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry RoHS or ROHS3 compliance certification. UX60SC-MB-5ST(80) and TE Connectivity 1-1734035-2 and 2-1734035-2 are ROHS3 compliant. UX60SC-MB-5ST(85) and 1-1734035-3 are RoHS compliant. GCT USB2066-05-RBHM-15-STB-00-00-A is ROHS3 compliant.

Q: What is the moisture sensitivity level for these connectors?

A: All Hirose and TE Connectivity parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. GCT USB2066-05-RBHM-15-STB-00-00-A is marked as Not Applicable for MSL, indicating no moisture sensitivity concern.
