U43SCWZQE2 Toggle Switch 4PDT Equivalent & Substitute Parts

Part Overview

The U43SCWZQE2 is a 4PDT toggle switch manufactured by C&K, rated for 5A at 120V AC and 28V DC. This panel-mount switch features a standard round actuator with solder lug termination and IP67 ingress protection. The product is active and ROHS3 compliant. Equivalent parts are identified when applications require alternative sourcing due to inventory constraints, supply chain considerations, or manufacturer discontinuation.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the U43SCWZQE2 are qualified based on strict electrical and mechanical parameter matching:

Critical Matching Parameters:

• Circuit configuration (4PDT)
• Switch function (On-Off-On)
• Current rating (5A AC/DC)
• Voltage ratings (120V AC, 28V DC)
• Mounting type (Panel Mount)
• Panel cutout dimensions (Circular - 6.35mm Dia)
• Bushing thread (1/4-40)
• Termination style (Solder Lug)
• Operating temperature range (-30°C ~ 85°C)
• Electrical life (40,000 Cycles)

The E-Switch models 1004P3T1B1M1QE and 1004P3T1B1M1QEH meet all critical electrical and mechanical parameters required for direct substitution. Minor variations in actuator length (10.41mm vs 10.67mm) and ingress protection rating do not affect functional compatibility in standard panel-mount applications.

Parameter Comparison

Engineering Selection Recommendations

Both E-Switch substitute parts (1004P3T1B1M1QE and 1004P3T1B1M1QEH) are qualified equivalents for the U43SCWZQE2. Selection between them should be based on:

Product Status: All three parts maintain active product status, ensuring continued availability and manufacturer support.

Compliance: All parts are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS classifications, meeting regulatory requirements for equivalent substitution.

Certifications: All parts share MSL 1 (Unlimited) moisture sensitivity rating and identical electrical life specifications (40,000 cycles), confirming equivalent reliability performance.

Packaging Consideration: The U43SCWZQE2 is supplied in Tray packaging, while both E-Switch substitutes are supplied in Bulk packaging. Packaging format does not affect electrical or mechanical compatibility but may influence inventory management and handling procedures.

Frequently Asked Questions (FAQ)

Q: Can 1004P3T1B1M1QE and 1004P3T1B1M1QEH be used interchangeably with U43SCWZQE2?

A: Yes. Both E-Switch parts meet all critical electrical parameters (4PDT, 5A, 120V AC, 28V DC) and mechanical specifications (panel mount, 6.35mm cutout, 1/4-40 bushing, solder lug termination). The 0.26mm difference in actuator length does not affect functional compatibility in standard panel-mount applications.

Q: What is the difference between 1004P3T1B1M1QE and 1004P3T1B1M1QEH?

A: Both parts are electrically and mechanically identical. The "H" suffix in 1004P3T1B1M1QEH indicates a variant designation within the E-Switch 100 series but does not reflect functional differences relevant to substitution criteria.

Q: Does the IP67 rating difference affect substitution?

A: The U43SCWZQE2 specifies IP67 (dust tight, waterproof) while the E-Switch substitutes do not list an ingress protection rating. For applications requiring IP67 environmental sealing, the U43SCWZQE2 remains the specified choice. For standard panel-mount applications without specific ingress protection requirements, the E-Switch parts are functionally equivalent.

Q: Are there packaging implications for using bulk-packaged substitutes?

A: The E-Switch substitutes are supplied in Bulk packaging versus the Tray packaging of the U43SCWZQE2. This affects handling, storage, and inventory management but does not impact electrical or mechanical performance. Confirm packaging requirements with procurement before substitution.

Q: Do all parts meet the same regulatory standards?

A: Yes. All three parts are ROHS3 compliant, carry EAR99 ECCN classification, and share identical HTSUS codes (8536.50.9065), confirming equivalent regulatory status for direct substitution.
