Substitute Part Grouping Explanation

Substitute parts for the USB-A-S-S-W-SM2 are identified based on strict parameter matching within the USB-A connector series from Samtec Inc. The substitution logic is based on the following critical parameters:

Electrical Compatibility Parameters:

• USB 2.0 specification compliance
• 4-position contact configuration
• 30VAC voltage rating
• 1500 mating cycle rating
• Gold contact finish
• Copper alloy shell material
• UL94 V-0 flammability rating

Mechanical Compatibility Parameters:

• Receptacle gender
• Surface mount and through-hole mounting capability
• Right-angle horizontal orientation
• Solder termination method
• Board guide and solder retention features

Identified Substitute Parts:

1. USB-A-S-F-B-SM2 – Differs only in insulation color (Black vs. White)
2. USB-A-S-S-B-SM2 – Differs only in insulation color (Black vs. White)
3. USB-A-S-S-W-SM2 – Identical part (same insulation color)

All three substitute parts maintain identical electrical specifications, mechanical mounting characteristics, and functional performance parameters. The only variation is insulation color, which does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain full electrical and mechanical compatibility with the USB-A-S-S-W-SM2. Selection among equivalent parts is determined by the following factors:

Compliance and Certification: All substitute parts carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and EAR99 export classification. All parts maintain UL94 V-0 flammability rating and Moisture Sensitivity Level 1 (Unlimited).

Product Status: All parts maintain Active product status, ensuring continued availability and manufacturing support.

Insulation Color Consideration: The primary differentiator among substitute parts is insulation color. USB-A-S-F-B-SM2 and USB-A-S-S-B-SM2 feature black insulation, while USB-A-S-S-W-SM2 features white insulation. Selection should be based on design specifications, PCB color coordination, or visual identification requirements.

Inventory Availability: Current stock levels vary: USB-A-S-F-B-SM2 (1823 units), USB-A-S-S-B-SM2 (1593 units), and USB-A-S-S-W-SM2 (1927 units). Inventory status may influence selection for immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: Are all listed substitute parts electrically identical to the USB-A-S-S-W-SM2?

A: Yes. All substitute parts comply with USB 2.0 specification, maintain identical 4-position contact configuration, 30VAC voltage rating, 1500 mating cycle rating, and gold contact finish. Electrical performance and signal integrity are equivalent across all parts.

Q: What is the only difference between the substitute parts?

A: Insulation color is the only difference. USB-A-S-F-B-SM2 and USB-A-S-S-B-SM2 feature black insulation, while USB-A-S-S-W-SM2 features white insulation. All other electrical, mechanical, and compliance parameters are identical.

Q: Can I use a black insulation connector (USB-A-S-S-B-SM2) in place of the white insulation connector (USB-A-S-S-W-SM2)?

A: Yes, from an electrical and mechanical standpoint, black and white insulation variants are fully interchangeable. Selection should be based on design requirements, PCB aesthetics, or visual identification needs.

Q: Are all parts RoHS3 compliant?

A: Yes. All listed parts carry ROHS3 Compliant certification and REACH Unaffected status, meeting current environmental and regulatory requirements.

Q: What is the operating temperature range for these connectors?

A: All parts operate within -50°C to 85°C temperature range, suitable for industrial and commercial applications.

Q: Do these connectors support both surface mount and through-hole mounting?

A: Yes. All parts support both Surface Mount and Through Hole mounting configurations with right-angle horizontal orientation.

Q: What is the mating cycle rating?

A: All parts are rated for 1500 mating cycles, indicating durability for repeated connection and disconnection operations.

Q: Are these parts suitable for high-speed USB applications?

A: These connectors comply with USB 2.0 specification. For applications requiring higher data rates, USB 3.0 or USB 3.1 connectors should be evaluated.
