A-USB A-TOP-THR1 Equivalent & Substitute Parts

Part Overview

The A-USB A-TOP-THR1 is a USB 2.0 Type-A receptacle connector manufactured by Assmann WSW Components. This through-hole mounted connector features 4 positions, vertical orientation, and solder termination. The connector is rated for 1.5A current and 1500 mating cycles, with gold-plated contacts and steel shielding. Currently in active product status with 792 units in stock, this connector serves as a standard interface component in USB 2.0 applications requiring vertical PCB mounting.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative sourcing reduces lead times or costs, or when design requirements necessitate different mechanical or electrical characteristics within the USB 2.0 Type-A receptacle category.

Engineering Selection Recommendations

Full Parameter Match (Recommended Primary Substitutes):

GSB11122BNEU (Amphenol ICC) and GSB11111KEU (Amphenol ICC) provide the closest functional equivalence to the A-USB A-TOP-THR1. Both maintain 1.5A current rating, 1500 mating cycles, and identical mounting specifications. GSB11122BNEU specifically matches the steel shielding material and black insulation color of the primary part. Both are ROHS3 compliant and in active product status with substantial inventory availability (3193 and 4746 units respectively).

Extended Temperature Range Alternative:

KUSBVLPXHT-AS1N-O30-HRF (Kycon, Inc.) extends the operating temperature range to -40°C ~ 105°C, providing enhanced thermal performance for applications requiring operation beyond the standard -55°C ~ 85°C range. This part maintains 1.5A current rating and 1500 mating cycles with stainless steel shielding and RoHS compliance.

Current-Limited Alternatives:

CU01SAV1S00 and CU01SAV0S00 (Cvilux USA) and PCUA20E (Switchcraft Inc.) are rated for 1A current. These parts are suitable only for applications where the circuit design does not require the full 1.5A capacity of the primary part. All three maintain USB 2.0 Type-A receptacle specifications and through-hole vertical mounting.

Product Status Consideration:

All substitute parts listed are in active product status, ensuring continued availability and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can I substitute a 1A-rated connector for the 1.5A-rated A-USB A-TOP-THR1?

A: Substitution is possible only if your application circuit design does not require current delivery exceeding 1A. The 1A-rated alternatives (CU01SAV0S00, CU01SAV1S00, PCUA20E) are mechanically and electrically compatible for USB 2.0 Type-A through-hole vertical mounting, but they have reduced current capacity. Verify your application's actual current requirements before selecting a 1A-rated substitute.

Q: What is the difference between steel and brass shielding materials?

A: Both steel (SPCC) and brass shielding materials are acceptable for USB 2.0 Type-A receptacle connectors and provide equivalent electromagnetic shielding performance. The choice between them is determined by application-specific requirements such as corrosion resistance, cost, or mechanical durability. GSB11122BNEU uses steel shielding identical to the primary part, while GSB11111KEU, GSB11120KEU, GSB11121KEU, and GSB11124KEU use brass shielding.

Q: Does insulation color affect connector functionality?

A: Insulation color is a functional variation only and does not affect electrical or mechanical performance. Color selection is typically used for circuit board assembly identification or design aesthetics. All substitute parts with different insulation colors (white, natural, yellow, orange) are fully compatible with the primary part's functional requirements.

Q: What is the significance of the operating temperature range difference?

A: The A-USB A-TOP-THR1 operates from -55°C ~ 85°C. Most substitute parts operate from -40°C ~ 85°C, which is acceptable for standard industrial and commercial applications. KUSBVLPXHT-AS1N-O30-HRF extends to -40°C ~ 105°C for applications requiring enhanced high-temperature performance. Select a substitute based on your application's actual operating temperature requirements.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed are either ROHS3 compliant or RoHS compliant, matching the primary part's environmental compliance status. This ensures compatibility with regulatory requirements for electronic component sourcing.

Q: What inventory levels should I consider when selecting a substitute?

A: Inventory availability ranges from 1705 to 8643 units across the substitute parts listed. GSB11120KEU offers the highest inventory (7378 units), while PCUA20E offers the lowest (1705 units). Consider inventory levels in relation to your procurement timeline and volume requirements.
