Substitute Part Grouping Explanation

Substitute parts for USB-AM-S-F-W-SM1-R are identified based on strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Connector Type: USB-A (USB TYPE-A)
• Specifications: USB 2.0
• Number of Contacts: 4 positions
• Shielding: Shielded configuration
• Contact Finish: Gold plating

Mechanical Equivalence Criteria:

• Gender: Plug
• Mounting Type: Surface Mount with Right Angle orientation and Through Hole capability
• Mounting Feature: Horizontal
• Termination: Solder

Environmental & Compliance Criteria:

• Operating Temperature Range: -50°C ~ 85°C (or compatible range)
• RoHS Status: ROHS3 Compliant
• Regulatory Classification: EAR99

The three identified substitute parts—USB-AM-S-F-B-SM1, USB-AM-S-S-B-SM1 (both Samtec Inc.), and 0480371000 (Molex)—satisfy all mandatory electrical and mechanical parameters. Variations in insulation color (White vs. Black) and secondary specifications do not affect functional interchangeability in USB 2.0 applications.

Parameter Comparison

Engineering Selection Recommendations

Samtec Inc. Substitutes (USB-AM-S-F-B-SM1 and USB-AM-S-S-B-SM1):

These parts maintain identical electrical and mechanical specifications to the primary part USB-AM-S-F-W-SM1-R. Both are ROHS3 Compliant with Active product status. The primary distinction is insulation color (Black vs. White), which does not affect electrical performance or mechanical compatibility. Both parts demonstrate higher inventory availability (1400 and 1099 units respectively) compared to the original part. Selection between these two Samtec variants depends on PCB assembly documentation requirements regarding connector color specification.

Molex Substitute (0480371000):

The Molex 0480371000 provides cross-manufacturer equivalence with identical connector type, USB 2.0 specification, 4-position configuration, and surface mount right-angle mounting. This part is ROHS3 Compliant and maintains Active product status. The Molex part demonstrates the highest inventory availability at 7928 units. Operating temperature range extends to -20°C (vs. -50°C minimum on Samtec parts), and rated voltage is specified at 150VAC (vs. 30VAC on Samtec parts), indicating enhanced electrical ratings. Mating cycle specification is not provided for the Molex part. Selection of the Molex alternative is appropriate when cross-manufacturer sourcing is acceptable and higher inventory levels are prioritized.

Frequently Asked Questions (FAQ)

Q: Can USB-AM-S-F-B-SM1 directly replace USB-AM-S-F-W-SM1-R?

A: Yes. Both parts share identical electrical specifications (USB 2.0, 4-position, shielded), mechanical mounting configuration (surface mount, right angle, horizontal), and environmental ratings (-50°C ~ 85°C). The insulation color difference (Black vs. White) does not affect functional interchangeability. Verify PCB assembly documentation does not mandate specific connector color before substitution.

Q: What is the difference between USB-AM-S-F-B-SM1 and USB-AM-S-S-B-SM1?

A: Both parts are manufactured by Samtec Inc. and share identical electrical and mechanical specifications. The part number variation reflects internal Samtec design designations but does not result in functional differences for USB 2.0 applications. Both are suitable substitutes for the original part.

Q: Is the Molex 0480371000 compatible with applications designed for USB-AM-S-F-W-SM1-R?

A: Yes. The Molex part meets all critical electrical and mechanical equivalence criteria: USB-A connector type, USB 2.0 specification, 4-position configuration, shielded design, surface mount right-angle mounting, and solder termination. The Molex part specifies higher voltage rating (150VAC vs. 30VAC) and current rating (1.5A), which provides enhanced electrical capability. Operating temperature minimum is -20°C (vs. -50°C on Samtec), which may be a consideration for extreme low-temperature applications.

Q: Does insulation color affect USB 2.0 signal integrity?

A: No. Insulation color is a visual identification feature and does not affect electrical performance, signal integrity, or mechanical function in USB 2.0 applications. Selection between White (USB-AM-S-F-W-SM1-R) and Black (substitute parts) is determined by PCB assembly specifications or design documentation requirements.

Q: Are all substitute parts ROHS3 Compliant?

A: Yes. USB-AM-S-F-B-SM1, USB-AM-S-S-B-SM1, and 0480371000 are all ROHS3 Compliant, matching the compliance status of the original USB-AM-S-F-W-SM1-R part.

Q: Which substitute part offers the best inventory availability?

A: The Molex 0480371000 provides the highest inventory level at 7928 units in stock, compared to 1400 units for USB-AM-S-F-B-SM1 and 1099 units for USB-AM-S-S-B-SM1. Selection based on inventory should be balanced against any cross-manufacturer qualification requirements in your design documentation.
