Key Parameters

Substitute Part Grouping Explanation

Substitution of the 34BWDP32B1M1RT is determined by compatibility across the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit Configuration: DPDT (Double-Pole Double-Throw)
• Switch Function: On-Off-On
• Mounting Type: Panel Mount
• Termination Style: Solder Lug
• Panel Cutout Dimensions: Circular - 6.35mm Dia
• Bushing Thread: 1/4-40

Electrical Performance Parameters:

• Current Rating: Must equal or exceed 0.4VA
• Voltage Rating - AC: Must equal or exceed 20V
• Voltage Rating - DC: Must equal or exceed 20V

Environmental & Compliance Parameters:

• Operating Temperature Range: Must encompass -30°C ~ 85°C
• RoHS Status: ROHS3 Compliant
• Ingress Protection: IP57 or higher acceptable

The substitute part E203SYZQE from C&K meets all mandatory compatibility parameters and exceeds electrical performance specifications, making it a valid substitute for applications where higher current and voltage ratings are acceptable.

Engineering Selection Recommendations

Primary Part: 34BWDP32B1M1RT

The 34BWDP32B1M1RT remains the preferred selection for applications requiring the specified electrical characteristics of 0.4VA at 20V. This part offers superior electrical life (50,000 cycles) and enhanced ingress protection (IP67), providing optimal performance in sealed environments. The part is in active production status with robust inventory availability (1136 units).

Substitute Part: E203SYZQE

The E203SYZQE from C&K is a valid substitute when the 34BWDP32B1M1RT is unavailable or when application requirements permit higher electrical ratings. This substitute provides increased current capacity (7.5A) and voltage ratings (125V AC, 28V DC), offering design flexibility for applications with evolving power requirements. Both parts maintain ROHS3 compliance and identical mechanical interfaces. The E203SYZQE operates within the same temperature range and features equivalent termination and mounting characteristics.

Selection Criteria:

• Select 34BWDP32B1M1RT for applications requiring IP67 sealing and maximum electrical cycle life
• Select E203SYZQE when higher current or voltage capacity is required and IP57 protection is acceptable
• Both parts are suitable for -30°C to 85°C operating environments
• Both parts comply with ROHS3 regulations and feature identical panel mounting interfaces

Frequently Asked Questions (FAQ)

Q: Can the E203SYZQE replace the 34BWDP32B1M1RT in all applications?

A: The E203SYZQE is mechanically and functionally compatible with the 34BWDP32B1M1RT for panel-mount DPDT On-Off-On switching applications. However, the E203SYZQE provides IP57 ingress protection compared to the IP67 rating of the 34BWDP32B1M1RT. Applications requiring IP67 sealing must retain the original part. The E203SYZQE also has a lower electrical life rating (40,000 cycles versus 50,000 cycles).

Q: Are the panel cutout dimensions identical between these parts?

A: Yes. Both the 34BWDP32B1M1RT and E203SYZQE feature a circular panel cutout of 6.35mm diameter with a 1/4-40 bushing thread, enabling direct mechanical substitution without panel modification.

Q: What is the difference in electrical ratings between these switches?

A: The 34BWDP32B1M1RT is rated for 0.4VA at 20V AC/DC. The E203SYZQE is rated for 7.5A at 125V AC and 28V DC. The E203SYZQE provides significantly higher electrical capacity and is suitable for applications requiring greater power handling. The 34BWDP32B1M1RT is appropriate for low-power control circuits.

Q: Do both parts use the same termination method?

A: Yes. Both the 34BWDP32B1M1RT and E203SYZQE employ solder lug termination, allowing identical PCB integration and wiring practices.

Q: Are there temperature operating range differences?

A: No. Both parts operate across the identical temperature range of -30°C to 85°C, ensuring equivalent thermal performance in environmental applications.

Q: What is the significance of the DPDT On-Off-On configuration?

A: DPDT (Double-Pole Double-Throw) On-Off-On configuration provides three stable positions: two active switching positions with a center off position. This allows independent control of two separate circuits with a neutral center state. Both substitute parts maintain this identical functionality.

Q: Are both parts RoHS compliant?

A: Yes. Both the 34BWDP32B1M1RT and E203SYZQE are ROHS3 compliant, meeting current environmental and hazardous substance restrictions for electronic components.
