Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the USB1125-GF-B are qualified based on the following critical parameters that must align with the original specification:

Mandatory Matching Parameters:

• Connector Type: USB-A (USB TYPE-A)
• Specifications: USB 2.0
• Number of Contacts: 4
• Gender: Receptacle
• Mounting Type: Through Hole, Right Angle
• Mounting Feature: Horizontal
• Termination: Solder
• Number of Ports: 1
• Shielding: Shielded
• Contact Finish: Gold
• Material Flammability Rating: UL94 V-0
• Features: Board Lock
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts meeting these criteria are functionally equivalent and can be used as direct replacements. Variations in shell/shielding material, insulation color, operating temperature range, current rating, voltage rating, and mating cycles do not preclude substitution when the mandatory parameters align.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts meet the mandatory electrical and mechanical parameters required for direct replacement of the USB1125-GF-B. Each substitute part carries Active product status and ROHS3 compliance certification, confirming regulatory alignment with the original component.

Compliance Considerations:

All substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, matching the original specification. REACH status varies between REACH Unaffected and Vendor Undefined designations; parts with REACH Unaffected status (61400416021, 896-43-004-90-000000, KUSBEX-ASFS1N-B, KUSBEX-ASFS1N-B30, KUSBEX-ASFS1N-W, SS-52100-001, USB-A-S-F-B-TH, USB-A-S-RA) provide explicit regulatory confirmation.

Performance Variations:

The USB1125-GF-B specifies 3A current rating and 5000 mating cycles. Substitute parts specify lower current ratings (1A to 1.5A) and reduced mating cycles (1500 cycles). These variations do not affect substitution eligibility when the application current and cycle requirements align with substitute part specifications.

Operating temperature ranges vary across substitute parts. The USB1125-GF-B operates from -30°C to 85°C. Substitute parts with extended temperature ranges (-40°C to 105°C) provide broader environmental capability. Parts with narrower ranges (USB-A-S-RA: -20°C to 60°C) require application-specific temperature validation.

Material Variations:

Shell/shielding materials differ across substitute parts (Steel SK7, Brass, Stainless Steel, Copper Alloy). All materials support equivalent electromagnetic shielding performance for USB 2.0 applications. Insulation color variations (Black, White, or unspecified) do not affect electrical function.

Frequently Asked Questions (FAQ)

Q: Can I substitute the USB1125-GF-B with any of the listed parts?

A: Yes. All listed parts meet the mandatory electrical and mechanical parameters: USB-A connector type, USB 2.0 specification, 4-position receptacle configuration, through-hole right-angle mounting, solder termination, board-lock features, gold contact finish, UL94 V-0 flammability rating, ROHS3 compliance, and MSL 1 rating. These parameters ensure functional equivalence and direct replacement capability.

Q: What is the difference between the substitute parts?

A: Substitute parts differ in manufacturer, shell material composition, insulation color, operating temperature range, current rating, mating cycle rating, and REACH compliance status. The core USB 2.0 receptacle function remains identical across all parts. Selection should prioritize application-specific requirements for current handling, temperature environment, and regulatory documentation needs.

Q: Does the insulation color affect compatibility?

A: No. Insulation color (Black or White) is a visual identifier only and does not affect electrical performance or mechanical compatibility. Selection of insulation color is based on assembly documentation or visual identification requirements.

Q: Are there current rating limitations I should consider?

A: The USB1125-GF-B specifies 3A current rating. Most substitute parts specify 1A to 1.5A current ratings. If your application requires 3A continuous current, verify that the selected substitute part current rating meets or exceeds your design requirement. For standard USB 2.0 applications, 1.5A is typically sufficient.

Q: What is the significance of mating cycle ratings?

A: The USB1125-GF-B specifies 5000 mating cycles. Most substitute parts specify 1500 mating cycles. Mating cycles indicate the number of connect/disconnect operations the connector can withstand. For applications with frequent connection cycling, select a part with mating cycle rating appropriate to your use case.

Q: Does operating temperature range affect substitution?

A: Operating temperature range does not preclude substitution but should align with your application environment. The USB1125-GF-B operates from -30°C to 85°C. Substitute parts with extended ranges (-40°C to 105°C) provide broader environmental capability. Parts with narrower ranges require validation that your application temperature profile falls within specification.

Q: What is REACH Unaffected status?

A: REACH Unaffected status indicates that the component is not subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulatory requirements. Vendor Undefined status indicates that REACH compliance information has not been provided by the manufacturer. For applications requiring explicit REACH documentation, select parts with REACH Unaffected designation.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes. All substitute parts share identical footprints, pin configurations, and mounting requirements (through-hole, right-angle, horizontal orientation). PCB layout and assembly processes require no modification when substituting between listed parts.

Q: What shell material should I select?

A: Shell material (Steel SK7, Brass, Stainless Steel, or Copper Alloy) does not affect USB 2.0 electrical performance. Material selection is based on mechanical durability, corrosion resistance, and manufacturing process compatibility. Brass and Copper Alloy materials provide superior corrosion resistance in humid environments. Steel materials offer cost optimization for standard applications.
