U41SYZGE Toggle Switch 4PDT 5A 120V Equivalent & Substitute Parts

Part Overview

The U41SYZGE is an active production toggle switch manufactured by C&K, classified as a 4PDT (four-pole double-throw) panel mount switch rated for 5A at 120V AC and 28V DC. This component is designed for applications requiring simultaneous switching of four independent circuits with On-On functionality. The switch features epoxy sealed terminals, non-illuminated operation, and solder lug termination suitable for direct PCB or panel integration. Finding equivalent and substitute parts is necessary to ensure supply chain flexibility, manage inventory across multiple suppliers, and maintain design continuity when primary components experience availability constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the U41SYZGE is determined by strict equivalence across the following critical parameters:

Circuit configuration must remain 4PDT with On-On switching function to maintain electrical functionality across all four poles simultaneously. Current and voltage ratings must meet or exceed 5A at 120V AC and 28V DC to ensure safe operation within the original design envelope. Panel mount configuration with circular 6.35mm diameter cutout and 1/4-40 bushing thread ensures mechanical compatibility with existing panel layouts. Solder lug termination is required for direct integration into the same assembly process. Operating temperature range of -30°C to 85°C must be supported. RoHS3 compliance is mandatory for regulatory alignment. The substitute part 1004P1T1B1M1QEH from E-Switch meets all these critical parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the U41SYZGE and 1004P1T1B1M1QEH are active production components with ROHS3 compliance, ensuring regulatory alignment for current and future applications. The U41SYZGE offers extended electrical life at 100,000 cycles compared to the E-Switch substitute at 40,000 cycles. Selection between these parts should be based on application duty cycle requirements. For applications with frequent switching operations exceeding 40,000 cycles, the U41SYZGE is the preferred choice. For applications within the 40,000-cycle envelope, the 1004P1T1B1M1QEH provides functional equivalence with identical electrical and mechanical specifications. Both components support the same panel integration methodology and termination approach.

Frequently Asked Questions (FAQ)

Q: Can the 1004P1T1B1M1QEH directly replace the U41SYZGE in existing designs?

A: Yes, the 1004P1T1B1M1QEH is mechanically and electrically compatible. Both components share identical panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), current rating (5A AC/DC), voltage ratings (120V AC, 28V DC), and termination style (solder lug). The primary difference is electrical life rating.

Q: What is the significance of the 100,000-cycle versus 40,000-cycle electrical life difference?

A: Electrical life indicates the number of complete on-off switching cycles the component can perform before degradation. The U41SYZGE supports twice the cycle count of the E-Switch substitute. Applications with high-frequency switching should specify the U41SYZGE to ensure component longevity.

Q: Are there packaging differences between these parts?

A: The U41SYZGE is supplied in Tray packaging with 859 pieces in stock, while the 1004P1T1B1M1QEH is supplied in Bulk packaging with 1833 pieces available. Packaging format does not affect component functionality or compatibility.

Q: Do both parts meet the same regulatory requirements?

A: Yes, both the U41SYZGE and 1004P1T1B1M1QEH are ROHS3 compliant. The U41SYZGE carries REACH Affected status, while the E-Switch substitute is REACH Unaffected. Verify REACH compliance requirements for your specific application and jurisdiction.

Q: What is the actuator length difference between these components?

A: The U41SYZGE has an actuator length of 10.67mm, while the 1004P1T1B1M1QEH measures 10.41mm. This 0.26mm difference is within typical mechanical tolerance and does not affect panel mount compatibility or operational function.
