Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the A-USB/2-B-TOP are qualified based on the following mandatory parameters:

• Connector Type: USB-B (USB TYPE-B)
• Specifications: USB 2.0
• Number of Contacts: 4
• Gender: Receptacle
• Mounting Type: Through Hole
• Mounting Feature: Vertical
• Termination: Solder
• Features: Board Lock
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Product Status: Active

All three substitute parts (5787834-1, 5787834-2, and USBR-B-S-F-O-VT) meet these core electrical and mechanical requirements, confirming parametric equivalence for direct circuit board substitution.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active product status and full compliance with ROHS3 requirements and MSL 1 specifications. Selection between substitute options is based on availability and supply chain considerations:

5787834-1 and 5787834-2 (TE Connectivity AMP Connectors) are parametrically identical with documented operating temperature range (-55°C ~ 85°C), current rating (1A per Contact), and mating cycle specification (1500 cycles). Both feature UL94 V-0 flammability rating. The primary difference is insulation color (Black for 5787834-1, Natural for 5787834-2) and inventory availability (1583 Pcs and 2300 Pcs respectively).

USBR-B-S-F-O-VT (Samtec Inc., USBR Series) provides equivalent electrical and mechanical performance with operating temperature range of -50°C ~ 85°C and 1500 mating cycles. Material flammability rating is not specified for this part. Inventory availability is 2232 Pcs.

Frequently Asked Questions (FAQ)

Q: Can 5787834-1 and 5787834-2 be used interchangeably with A-USB/2-B-TOP?

A: Yes. Both parts are parametrically equivalent USB 2.0 Type-B receptacle connectors with identical electrical specifications, 4-position through-hole vertical mount configuration, solder termination, board lock feature, and ROHS3 compliance. Insulation color differs (Black and Natural respectively) but does not affect electrical function.

Q: What is the difference between the TE Connectivity substitute parts (5787834-1 and 5787834-2)?

A: The parts are electrically and mechanically identical. The primary difference is insulation color: 5787834-1 features black insulation while 5787834-2 features natural insulation. Selection may be based on visual identification requirements or inventory availability.

Q: Is USBR-B-S-F-O-VT suitable for applications requiring UL94 V-0 certification?

A: USBR-B-S-F-O-VT material flammability rating is not specified in available documentation. If UL94 V-0 certification is a mandatory requirement, 5787834-1, 5787834-2, or the original A-USB/2-B-TOP are confirmed compliant alternatives.

Q: Are all substitute parts ROHS3 compliant?

A: 5787834-1 and USBR-B-S-F-O-VT are ROHS3 compliant. 5787834-2 is listed as RoHS Compliant without specific ROHS3 designation. All parts meet unlimited moisture sensitivity level (MSL 1) requirements.

Q: What are the operating temperature ranges for each part?

A: A-USB/2-B-TOP operating temperature is not specified. TE Connectivity parts (5787834-1 and 5787834-2) operate from -55°C to 85°C. Samtec USBR-B-S-F-O-VT operates from -50°C to 85°C. Selection should align with application temperature requirements.

Q: Can these connectors be used in high-cycle mating applications?

A: TE Connectivity (5787834-1, 5787834-2) and Samtec (USBR-B-S-F-O-VT) parts are rated for 1500 mating cycles. Mating cycle specification for A-USB/2-B-TOP is not provided. Applications requiring higher cycle counts should reference manufacturer datasheets for extended life specifications.
