USB-AM-S-S-W-SM1-R-TR Equivalent & Substitute Parts

Part Overview

The USB-AM-S-S-W-SM1-R-TR is a USB 2.0 Type-A plug connector manufactured by Samtec Inc., designed for surface mount and through-hole applications with right-angle orientation. This 4-position connector features a horizontal mounting configuration with solder termination and board guide support. The part is currently active in production and widely used in consumer electronics, industrial equipment, and computing peripherals requiring USB 2.0 connectivity.

Equivalent substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits component standardization across manufacturing facilities or product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the USB-AM-S-S-W-SM1-R-TR are qualified based on the following critical parameters:

• Connector Type & Gender: USB-A plug configuration (4-position)
• Interface Standard: USB 2.0 specification compliance
• Mounting Configuration: Surface mount with right-angle, horizontal orientation
• Termination Method: Solder attachment with board guide
• Electrical Protection: Shielded construction with gold-plated contacts
• Environmental Compliance: ROHS3 compliance and MSL 1 rating

The Molex 0480372100 and 0480372200 connectors meet all critical substitution criteria. Both parts share identical connector topology, mounting geometry, and functional specifications. Differences in operating temperature range and voltage rating do not preclude substitution, as these represent enhanced specifications within the USB 2.0 standard envelope.

Parameter Comparison

Engineering Selection Recommendations

Both Molex substitute parts (0480372100 and 0480372200) are functionally equivalent to the Samtec USB-AM-S-S-W-SM1-R-TR for USB 2.0 applications. Selection between these options is based on the following factors:

Product Status & Availability: All three parts maintain active production status. The Molex alternatives offer significantly higher inventory levels (17,610 and 25,131 units respectively) compared to the Samtec part (850 units), providing supply chain advantages.

Regulatory Compliance: All parts are ROHS3 compliant and carry MSL 1 rating, meeting standard environmental and moisture sensitivity requirements for surface mount assembly processes.

Electrical Performance: The Molex parts specify higher voltage ratings (150VAC versus 30VAC) and documented current capacity (1.5A), providing enhanced electrical margin within the USB 2.0 specification. These enhanced ratings do not introduce incompatibility and represent conservative design margins.

Temperature Operating Range: The Samtec part supports extended low-temperature operation (-50°C versus -20°C). Applications requiring operation below -20°C must retain the Samtec part. Standard commercial and industrial applications operate within the -20°C to 85°C range supported by both Molex alternatives.

Mechanical Compatibility: All three connectors share identical mounting geometry, right-angle orientation, and board guide configuration, ensuring direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can Molex 0480372100 and 0480372200 be used interchangeably with USB-AM-S-S-W-SM1-R-TR?

A: Yes. Both Molex parts are parametric equivalents meeting all critical USB 2.0 Type-A plug specifications, including connector topology, mounting configuration, and termination method. Direct substitution is supported for applications operating within the -20°C to 85°C temperature range.

Q: What is the difference between Molex 0480372100 and 0480372200?

A: Both parts are electrically and mechanically identical. The part number suffix variation reflects internal Molex product line differentiation. Selection between these two Molex alternatives does not affect functional performance or compatibility.

Q: Does the lower operating temperature range of Molex parts affect USB 2.0 compliance?

A: No. The Molex operating range of -20°C to 85°C fully encompasses standard commercial and industrial temperature specifications for USB 2.0 devices. Applications requiring operation below -20°C must use the Samtec USB-AM-S-S-W-SM1-R-TR.

Q: Are there mechanical footprint differences between these connectors?

A: No. All three connectors feature identical right-angle, horizontal mounting geometry with board guide support. PCB layouts designed for the Samtec part accommodate Molex substitutes without modification.

Q: What packaging formats are available for these substitute parts?

A: All three parts are supplied in Tape & Reel (TR) format, standard for surface mount assembly operations.

Q: Are all parts RoHS3 compliant?

A: Yes. The Samtec USB-AM-S-S-W-SM1-R-TR and both Molex alternatives (0480372100 and 0480372200) are ROHS3 compliant with MSL 1 moisture sensitivity rating.
