SX0790/63 Equivalent & Substitute Parts

Part Overview

The SX0790/63 is a toggle switch manufactured by Bulgin, featuring SPDT (Single Pole Double Throw) circuit configuration with On-Off-On switching function. Rated for 10A at 250V AC and 28V DC, this component is designed for panel mount applications with a circular 12.00mm diameter cutout. The product is currently obsolete, making identification of functionally equivalent alternatives necessary for ongoing maintenance, repair, and new design applications where legacy compatibility is not required.

Substitute Part Grouping Explanation

Substitution of the SX0790/63 is determined by the following critical parameters:

Circuit configuration must remain SPDT with On-Off-On switching function to maintain electrical functionality. Mounting type must be panel mount with compatible panel cutout dimensions. Termination style must be Quick Connect 0.250" (6.3mm) to ensure direct connection compatibility. Current and voltage ratings must meet or exceed the original specification (minimum 10A, minimum 250V AC). Operating temperature range must encompass or exceed the original range. RoHS3 compliance and REACH unaffected status must be maintained for regulatory alignment.

The GTS447D101HR from CW Industries satisfies these substitution criteria through equivalent circuit configuration, compatible mounting and termination specifications, and superior electrical ratings.

Engineering Selection Recommendations

The GTS447D101HR is the manufacturer-recommended substitute for the obsolete SX0790/63. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity. The substitute provides superior electrical ratings (16A at 277V AC versus 10A at 250V AC), enabling use in higher-demand applications. The GTS447D101HR carries active product status with documented electrical life specification of 10,000 cycles and IP56 ingress protection rating, providing enhanced reliability data for design validation. Panel cutout dimensions are compatible within standard manufacturing tolerances (12.00mm versus 12.20mm). The reduced actuator length (17.50mm versus 20.20mm) requires mechanical clearance verification in existing panel installations.

Frequently Asked Questions (FAQ)

Q: Can the GTS447D101HR directly replace the SX0790/63 in existing applications?

A: Direct electrical and termination compatibility is confirmed through matching SPDT circuit configuration, On-Off-On switching function, and Quick Connect 0.250" (6.3mm) termination. Panel cutout dimensions are compatible within standard tolerances. Mechanical clearance must be verified due to actuator length difference (17.50mm versus 20.20mm).

Q: What are the key differences in electrical ratings?

A: The GTS447D101HR provides higher current capacity (16A versus 10A) and higher AC voltage rating (277V versus 250V). DC voltage rating is not specified for the substitute. Applications operating at or below the original SX0790/63 ratings are fully supported by the substitute's superior specifications.

Q: Are both components compliant with current regulations?

A: Both the SX0790/63 and GTS447D101HR are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement and use.

Q: What is the significance of the IP56 rating on the substitute?

A: The GTS447D101HR includes IP56 ingress protection (dust protected, water resistant), providing enhanced environmental protection compared to the original component where ingress protection was not specified. This feature may provide additional reliability in applications exposed to moisture or particulate contamination.

Q: How does the operating temperature range differ?

A: The SX0790/63 operates from -20°C to 85°C, while the GTS447D101HR operates from 0°C to 85°C. Applications requiring operation below 0°C require verification that the substitute meets temperature requirements.

Q: What packaging is available for the GTS447D101HR?

A: The GTS447D101HR is supplied in bulk packaging, with 1113 pieces available in new original stock condition.
