A-USB A-TOP-C-THR1 USB 2.0 Type-A Receptacle Connector Equivalent & Substitute Parts

Part Overview

The A-USB A-TOP-C-THR1 is a USB 2.0 Type-A receptacle connector manufactured by Assmann WSW Components, designed for through-hole vertical mounting applications. This 4-position connector features a 1.5A current rating, gold-plated contacts, and steel shielding material. The part is actively produced and ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are necessary when the primary part becomes unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits selection from multiple qualified manufacturers meeting identical electrical and mechanical specifications.

Engineering Selection Recommendations

Full Electrical and Mechanical Equivalents (1.5A Current Rating, 1500 Mating Cycles):

GSB11111KEU, GSB11120KEU, GSB11121KEU, GSB11122BNEU, and GSB11124KEU (Amphenol ICC) provide complete parameter equivalence to the A-USB A-TOP-C-THR1, with operating temperature range of -40°C to 85°C. GSB11122BNEU matches the original part's steel (SPCC) shielding material. KUSBVLPXHT-AS1N-O30-HRF (Kycon) offers extended operating temperature range (-40°C to 105°C) and stainless steel shielding, suitable for applications requiring enhanced thermal performance.

Reduced Current Rating Alternatives (1.0A Current Rating):

CU01SAV0S00 and CU01SAV1S00 (Cvilux USA) and PCUA20E (Switchcraft Inc.) are suitable for applications where maximum current draw does not exceed 1.0A. These parts maintain USB 2.0 compliance, shielding, gold contact finish, and ROHS3 compliance. Operating temperature range for Cvilux parts is 0°C to 85°C; PCUA20E operating temperature is not specified.

Compliance and Certification Status:

All substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) rating. Amphenol ICC parts carry REACH Affected or REACH Unaffected designations; Cvilux and Kycon parts are REACH Unaffected. All parts are classified under ECCN EAR99 and HTSUS 8536.69.4040.

Frequently Asked Questions (FAQ)

Q: Can CU01SAV0S00 or CU01SAV1S00 replace A-USB A-TOP-C-THR1 in all applications?

A: These Cvilux parts are suitable only for applications where maximum sustained current does not exceed 1.0A. The original part is rated for 1.5A. If your design requires the full 1.5A current capacity, select GSB series (Amphenol ICC) or KUSBVLPXHT-AS1N-O30-HRF (Kycon) alternatives.

Q: What is the difference between GSB11122BNEU and other GSB11 variants?

A: GSB11122BNEU uses steel (SPCC) shielding material, matching the original A-USB A-TOP-C-THR1. Other GSB11 variants (GSB11111KEU, GSB11120KEU, GSB11121KEU, GSB11124KEU) use brass shielding. All maintain identical electrical specifications (1.5A, 1500 mating cycles, USB 2.0). Insulation color varies (Black, Natural, Yellow) for identification purposes.

Q: Does KUSBVLPXHT-AS1N-O30-HRF offer advantages over Amphenol GSB series?

A: KUSBVLPXHT-AS1N-O30-HRF extends the maximum operating temperature to 105°C (versus 85°C for GSB series) and uses stainless steel shielding. Both maintain 1.5A current rating and 1500 mating cycles. Selection depends on thermal environment requirements and shielding material compatibility with your application.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts are supplied in Tray packaging, matching the original A-USB A-TOP-C-THR1 packaging specification.

Q: What is the significance of insulation color variation?

A: Insulation color (White, Black, Natural, Yellow, Orange) is a cosmetic identifier and does not affect electrical or mechanical function. Selection may be based on PCB assembly color-coding standards or visual identification requirements in your manufacturing process.

Q: Can PCUA20E be used as a direct replacement?

A: PCUA20E is suitable only for applications with maximum current draw of 1.0A. Operating temperature range is not specified in available documentation. For applications requiring the full 1.5A rating or confirmed operating temperature specifications, select alternatives with complete parameter documentation.
