Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the USB-A-S-F-B-SM2 are identified based on the following critical parameters that determine functional equivalence:

Electrical Specifications:

• USB 2.0 protocol compliance
• 4-position contact configuration
• 30VAC rated voltage
• 1500 mating cycles

Mechanical Characteristics:

• Connector Type: USB-A (USB TYPE-A)
• Gender: Receptacle
• Mounting Type: Surface Mount, Right Angle; Through Hole
• Mounting Feature: Horizontal
• Termination: Solder

Material & Environmental Compliance:

• Contact Finish: Gold
• Shell/Shielding Material: Copper Alloy
• Material Flammability Rating: UL94 V-0
• Operating Temperature: -50°C ~ 85°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

The identified substitutes USB-A-S-S-B-SM2 and USB-A-S-S-W-SM2 share identical electrical and mechanical specifications with the main part. The primary differentiation is insulation color: Black for USB-A-S-S-B-SM2 and White for USB-A-S-S-W-SM2.

Parameter Comparison

Engineering Selection Recommendations

All three parts—USB-A-S-F-B-SM2, USB-A-S-S-B-SM2, and USB-A-S-S-W-SM2—maintain Active product status and are ROHS3 Compliant with REACH Unaffected designation. Each component carries identical electrical specifications, mechanical mounting characteristics, and environmental ratings.

Selection between these parts is determined by insulation color requirements and inventory availability. The USB-A-S-S-B-SM2 and USB-A-S-S-W-SM2 offer higher inventory levels (1593 and 1927 units respectively) compared to the main part number (925 units), providing supply chain advantages when color specification permits substitution.

All parts are classified under ECCN EAR99 and HTSUS 8536.69.4040, ensuring consistent regulatory treatment across substitution scenarios.

Frequently Asked Questions (FAQ)

Q: What determines if USB-A-S-S-B-SM2 or USB-A-S-S-W-SM2 can substitute for USB-A-S-F-B-SM2?

A: Substitution is valid when the design permits variation in insulation color. All three parts share identical electrical specifications (USB 2.0, 4-position, 30VAC rated), mechanical mounting characteristics (Surface Mount, Right Angle; Through Hole, Horizontal), and environmental ratings (-50°C ~ 85°C operating temperature, UL94 V-0 flammability). The only functional difference is insulation color: Black versus White.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist at the electrical or mechanical level. All parts feature identical contact configurations, termination methods (Solder), and board interface specifications. Insulation color does not affect electrical performance or mechanical fit.

Q: What is the significance of the insulation color difference?

A: Insulation color serves as a visual identifier and may be specified for design documentation, assembly traceability, or aesthetic requirements. From an engineering standpoint, color does not impact connector function, electrical performance, or mechanical compatibility.

Q: How do inventory levels affect part selection?

A: USB-A-S-S-B-SM2 (1593 units) and USB-A-S-S-W-SM2 (1927 units) offer greater stock availability than USB-A-S-F-B-SM2 (925 units). When design specifications permit color substitution, higher inventory parts reduce lead time risk and support production scheduling.

Q: Are all three parts subject to the same regulatory requirements?

A: Yes. All parts are ROHS3 Compliant, REACH Unaffected, classified under ECCN EAR99, and assigned HTSUS code 8536.69.4040. Regulatory treatment is identical across all three part numbers.

Q: What is the Moisture Sensitivity Level (MSL) for these connectors?

A: All three parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.
