A-USB A-TOP-C-THR USB 2.0 Type-A Receptacle Connector

Part Overview

The A-USB A-TOP-C-THR is a USB 2.0 Type-A female receptacle connector manufactured by Assmann WSW Components. This through-hole mounted connector features 4 positions with vertical orientation and solder termination, rated for 1.5A at operating temperatures from -55°C to 85°C. The connector is actively produced and ROHS3 compliant, designed for applications requiring reliable USB 2.0 connectivity with shielded construction and gold-plated contacts.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative sourcing is required for supply chain optimization, or when design flexibility permits selection from multiple qualified manufacturers meeting the same electrical and mechanical specifications.

Engineering Selection Recommendations

All listed substitute parts are actively produced and ROHS3 compliant, meeting the core substitution criteria. Selection among these alternatives depends on application-specific requirements:

Full Parameter Match: GSB11122BNEU provides the closest alignment to the A-USB A-TOP-C-THR, matching the steel (SPCC) shell material, black insulation color, 1.5A current rating, and 1500 mating cycle specification. Operating temperature range is -40°C to 85°C, which covers the upper portion of the primary part's range.

Extended Temperature Performance: KUSBVLPXHT-AS1N-O30-HRF extends the upper operating temperature to 105°C and features stainless steel construction, suitable for applications requiring enhanced thermal performance or corrosion resistance.

Amphenol ICC GSB1 Series: GSB11111KEU, GSB11120KEU, GSB11121KEU, and GSB11124KEU offer consistent 1.5A current rating and 1500 mating cycles with brass shell construction. These parts differ primarily in insulation color and operating temperature floor of -40°C.

Current-Limited Alternatives: CU01SAV0S00, CU01SAV1S00, and PCUA20E are rated for 1A current, suitable for applications where the full 1.5A capacity is not required.

All substitute parts maintain shielded construction, gold-plated contacts, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity level consistent with the primary part.

Frequently Asked Questions (FAQ)

Q: Can CU01SAV0S00 or CU01SAV1S00 be used as direct replacements for A-USB A-TOP-C-THR?

A: These Cvilux USA parts meet the core connector specifications but are rated for 1A maximum current versus 1.5A for the primary part. Substitution is valid only if the application current requirement does not exceed 1A. Operating temperature range is 0°C to 85°C, which does not extend to the -55°C lower limit of the primary part.

Q: What is the difference between GSB11122BNEU and other GSB1 series parts?

A: GSB11122BNEU features steel (SPCC) shell material matching the primary part, while GSB11111KEU, GSB11120KEU, GSB11121KEU, and GSB11124KEU use brass shells. All maintain identical electrical specifications: 1.5A current rating, 1500 mating cycles, and -40°C to 85°C operating temperature. Insulation color varies across the series.

Q: Is KUSBVLPXHT-AS1N-O30-HRF suitable for high-temperature applications?

A: Yes. KUSBVLPXHT-AS1N-O30-HRF is rated for -40°C to 105°C operating temperature, extending 20°C above the primary part's upper limit. Stainless steel construction provides additional corrosion resistance. This part is appropriate for applications requiring enhanced thermal performance.

Q: Do all substitute parts support the same mating cycle count?

A: No. GSB11111KEU, GSB11120KEU, GSB11121KEU, GSB11122BNEU, GSB11124KEU, and KUSBVLPXHT-AS1N-O30-HRF are rated for 1500 mating cycles, matching the primary part. CU01SAV0S00, CU01SAV1S00, and PCUA20E do not specify mating cycle ratings.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the primary part's compliance status.

Q: What shell material options are available among the substitutes?

A: Shell materials include steel (SPCC) in GSB11122BNEU and PCUA20E, brass in GSB11111KEU, GSB11120KEU, GSB11121KEU, and GSB11124KEU, and stainless steel in KUSBVLPXHT-AS1N-O30-HRF. The primary part uses steel (SPCC).
