Substitute Part Grouping Explanation
Substitution eligibility for the UX60RA-MB-5ST is determined by strict equivalence across the following critical parameters: connector type (USB - mini B), number of contacts (5), gender (Receptacle), USB specification (2.0), mounting configuration (Surface Mount, Right Angle, Horizontal), termination method (Solder), current rating (1A), shielding (Shielded), and material flammability rating (UL94 V-0).
Substitute parts are grouped into two categories:
Category 1: Hirose Electric Co Ltd UX Series — Parts UX60-MB-5ST(70), UX60SC-MB-5ST, UX60SC-MB-5ST(80), and UX60SC-MB-5ST(85) maintain identical connector architecture and electrical specifications. These parts differ in packaging format (Tape & Reel or Cut Tape), product status (Active or Last Time Buy), shell/shielding material composition, and contact finish specifications. All operate within the -30°C to 75°C temperature range with 5000 mating cycles.
Category 2: Cross-Manufacturer Equivalents — Parts 1-1734035-2, 1-1734035-3, and 2-1734035-2 from TE Connectivity AMP Connectors, and USB2066-05-RBHM-15-STB-00-00-A from GCT maintain functional equivalence with identical connector type, contact count, mounting configuration, and electrical ratings. These parts feature extended operating temperature ranges (-40°C to 85°C or -50°C to 85°C) and alternative shell materials (Steel SUS304 or Brass). All substitute parts maintain 1A current rating, shielded construction, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity.

Engineering Selection Recommendations
For new designs and production applications requiring replacement of the obsolete UX60RA-MB-5ST, the following selection criteria apply:
Active Product Status Priority: 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 maintain Active product status and are recommended for new designs. These parts ensure long-term supply availability and manufacturing support.
RoHS and ROHS3 Compliance: All substitute parts maintain RoHS compliance. Parts UX60SC-MB-5ST(80), 1-1734035-2, 2-1734035-2, and USB2066-05-RBHM-15-STB-00-00-A carry ROHS3 certification, meeting current regulatory requirements.
Temperature Operating Range: The original UX60RA-MB-5ST operates from -30°C to 75°C. TE Connectivity parts (1-1734035-2, 1-1734035-3, 2-1734035-2) extend this range to -40°C to 85°C, and GCT USB2066-05-RBHM-15-STB-00-00-A extends to -50°C to 85°C. Selection depends on application thermal requirements.
Packaging Considerations: Hirose UX60-MB-5ST(70) and UX60SC-MB-5ST(85) are available in Tape & Reel format suitable for automated assembly. TE Connectivity 1-1734035-2 is available in Cut Tape format. UX60SC-MB-5ST(80) is supplied in Cut Tape & Digi-Reel format. GCT USB2066-05-RBHM-15-STB-00-00-A is supplied in Tape & Reel format.
Voltage Rating Differences: The original part is rated 5VAC. Most substitute parts are rated 30VAC or 30VDC, providing higher voltage margin for applications operating at or below 5VAC.
Frequently Asked Questions (FAQ)
Q: Can UX60-MB-5ST(70) directly replace UX60RA-MB-5ST in existing designs?
A: Yes. UX60-MB-5ST(70) maintains identical connector type, contact configuration, mounting orientation, electrical ratings, and operating temperature range. The primary difference is product status (Active vs. Obsolete) and packaging format (Tape & Reel). PCB footprint compatibility must be verified for the specific application.
Q: What is the difference between UX60SC-MB-5ST and UX60SC-MB-5ST(80)?
A: Both parts are functionally equivalent USB 2.0 Mini B receptacle connectors with identical electrical specifications. UX60SC-MB-5ST(80) specifies 5000 mating cycles, while UX60SC-MB-5ST does not specify this parameter. UX60SC-MB-5ST(80) is supplied in Cut Tape & Digi-Reel format with higher inventory availability (32,714 pieces). Both carry Last Time Buy status.
Q: Are TE Connectivity 1-1734035-2 and 1-1734035-3 interchangeable?
A: Yes. Both parts are functionally equivalent with identical electrical specifications, current rating, voltage rating, mating cycles, and operating temperature range (-40°C to 85°C). The difference is packaging format: 1-1734035-2 is supplied in Cut Tape, while 1-1734035-3 is supplied in Tape & Reel.
Q: Why do some substitute parts have 30VAC or 30VDC ratings instead of 5VAC?
A: The voltage rating indicates the maximum rated voltage the connector can safely handle. A 30VAC or 30VDC rated connector is fully compatible with 5VAC applications and provides additional voltage margin. This does not affect USB 2.0 signal integrity or functionality.
Q: Is the GCT USB2066-05-RBHM-15-STB-00-00-A suitable for applications requiring extended temperature operation?
A: Yes. The GCT part operates from -50°C to 85°C, providing the widest temperature range among all substitute options. This makes it suitable for industrial and automotive applications with extended thermal requirements beyond the original -30°C to 75°C specification.
Q: What packaging format should be selected for high-volume automated assembly?
A: Tape & Reel format is standard for automated pick-and-place assembly. Recommended parts in this format include UX60-MB-5ST(70), UX60SC-MB-5ST(85), 1-1734035-3, 2-1734035-2, and USB2066-05-RBHM-15-STB-00-00-A. Cut Tape format (1-1734035-2) is suitable for lower-volume or manual assembly operations.
Q: Are all substitute parts RoHS compliant?
A: Yes. All substitute parts maintain RoHS compliance. Parts UX60SC-MB-5ST(80), 1-1734035-2, 2-1734035-2, and USB2066-05-RBHM-15-STB-00-00-A carry ROHS3 certification, meeting current regulatory standards for electronic components.
