Parameter Comparison

Engineering Selection Recommendations

The USB-C31-A-D-VT-CS1 is the designated substitute for the obsolete USB-A-C31-D-VT. The substitute part maintains Active product status, ensuring ongoing availability and manufacturer support. Both parts satisfy ROHS3 compliance, REACH unaffected status, and UL94 V-0 flammability requirements.

The substitute part supports enhanced specifications including USB 2.0 and USB 3.2 Gen 2 protocols with increased current ratings (5A, 8A) compared to the main part (1.25A). The shell material differs from copper alloy to steel/stainless construction, maintaining shielding effectiveness while providing alternative material properties.

Selection of the substitute part is appropriate for applications requiring the stacked USB-A and USB-C receptacle configuration with through-hole vertical mounting and solder termination.

Frequently Asked Questions (FAQ)

Q: What makes USB-C31-A-D-VT-CS1 a suitable substitute for USB-A-C31-D-VT?

A: Both parts share identical connector type (stacked USB-A and USB-C), contact count (28), mounting configuration (through-hole vertical), termination method (solder), and compliance certifications (ROHS3, REACH unaffected, UL94 V-0). The substitute maintains the same mechanical footprint and electrical interface requirements.

Q: Are there differences in electrical performance between the main part and substitute?

A: The substitute part supports higher current ratings (5A, 8A) and includes USB protocol specifications (USB 2.0, USB 3.2 Gen 2) not listed for the main part. The main part specifies 30VAC/DC rated voltage, while the substitute does not specify voltage rating in the provided parameters.

Q: Does the change in shell material from copper alloy to steel/stainless affect compatibility?

A: Both materials provide shielding functionality required for the connector type. The material change does not affect mechanical compatibility or electrical interface characteristics for the specified application parameters.

Q: What is the packaging difference?

A: The main part packaging is not specified. The substitute is supplied in Tray packaging, which is standard for production quantities of this connector type.

Q: Why is the main part classified as Obsolete?

A: Product obsolescence is determined by the manufacturer. The substitute part, classified as Active, provides continuity for designs requiring the stacked USB-A and USB-C receptacle configuration.
