Engineering Selection Recommendations
All substitute parts listed are actively produced and ROHS3 compliant, meeting regulatory requirements for electronic component applications. Selection among qualified substitutes should be based on the following factors:
Current Capacity Considerations: The A-USB A-TOP-THR is rated for 1.5A. Substitutes CU01SAV0S00, CU01SAV1S00, and PCUA20E are rated for 1.0A. These lower-rated parts are suitable for applications with current requirements not exceeding 1.0A. For applications requiring the full 1.5A capacity, select from GSB11111KEU, GSB11120KEU, GSB11121KEU, GSB11122BNEU, GSB11124KEU, or KUSBVLPXHT-AS1N-O30-HRF.
Temperature Range Considerations: The A-USB A-TOP-THR operates from -55°C to 85°C. Substitutes CU01SAV0S00 and CU01SAV1S00 operate from 0°C to 85°C, limiting their use in applications requiring extended low-temperature performance below 0°C. The KUSBVLPXHT-AS1N-O30-HRF extends the upper operating range to 105°C, suitable for high-temperature applications.
Shell Material Compatibility: Steel (SPCC) shell material matches the original part in GSB11122BNEU. Brass shell variants (GSB11111KEU, GSB11120KEU, GSB11121KEU, GSB11124KEU) and stainless steel (KUSBVLPXHT-AS1N-O30-HRF) provide alternative shielding characteristics. Material selection should align with electromagnetic compatibility and corrosion resistance requirements.
Inventory Availability: GSB11120KEU (7378 pcs), GSB11124KEU (8643 pcs), and KUSBVLPXHT-AS1N-O30-HRF (6183 pcs) offer the highest stock levels for immediate procurement.
Frequently Asked Questions (FAQ)
Q: Can CU01SAV0S00 or CU01SAV1S00 be used as direct replacements for the A-USB A-TOP-THR?
A: These Cvilux parts are mechanically and electrically compatible for applications with current requirements up to 1.0A and operating temperatures between 0°C and 85°C. Applications requiring the full 1.5A capacity or operation below 0°C require substitutes with matching specifications.
Q: What is the difference between GSB11120KEU and GSB11121KEU?
A: Both parts are manufactured by Amphenol ICC with identical electrical and mechanical specifications. The primary difference is insulation color: GSB11120KEU features natural insulation, while GSB11121KEU features black insulation. Functional performance is equivalent.
Q: Is KUSBVLPXHT-AS1N-O30-HRF suitable for high-temperature applications?
A: Yes. The KUSBVLPXHT-AS1N-O30-HRF operates from -40°C to 105°C, extending the upper temperature limit by 20°C compared to the A-USB A-TOP-THR. This part is qualified for applications requiring sustained operation at elevated temperatures.
Q: Why do some substitute parts not specify mating cycle ratings?
A: CU01SAV0S00, CU01SAV1S00, and PCUA20E do not provide mating cycle specifications in available documentation. The A-USB A-TOP-THR and most Amphenol and Kycon substitutes are rated for 1500 mating cycles. Mating cycle performance should be verified with manufacturers if this parameter is critical to application requirements.
Q: Can I use GSB11122BNEU as a direct replacement for the A-USB A-TOP-THR?
A: Yes. GSB11122BNEU matches the original part in shell material (Steel SPCC), current rating (1.5A), mating cycles (1500), and all other critical parameters. The primary difference is insulation color (black versus white), which does not affect electrical or mechanical function.
Q: What is the significance of the different insulation colors among substitute parts?
A: Insulation color is a cosmetic and identification feature that does not affect electrical or mechanical performance. Color selection may be driven by application aesthetics, internal documentation standards, or manufacturing availability. All listed parts with different insulation colors are functionally equivalent.
