APEM 8432WCDB Pushbutton Switch SPDT Equivalent & Substitute Parts

Part Overview

The APEM 8432WCDB is an active-status pushbutton switch featuring SPDT (Single Pole Double Throw) circuitry with momentary operation. Rated for 0.4VA at 20V AC/DC, this component is designed for standard panel mount applications with right-angle rear termination. The switch employs PC pin termination with epoxy sealed terminals and operates across -40°C to 85°C. Finding equivalent or substitute parts may be necessary due to inventory constraints, lead time requirements, or specific application demands while maintaining functional compatibility within defined electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the APEM 8432WCDB is evaluated based on the following critical parameters that define functional compatibility:

Circuit Configuration: Both main and substitute parts must maintain SPDT topology to preserve switching logic.

Switch Function: Momentary operation (On-Mom) must be preserved for application consistency.

Mounting and Termination: Panel mount configuration with right-angle rear termination and PC pin termination are required for mechanical and electrical interface compatibility.

Electrical Ratings: Substitute parts must operate within or exceed the specified voltage (20V AC/DC) and current (0.4VA) ratings to ensure safe operation in the intended application.

Panel Cutout Dimensions: Circular panel cutout specifications must be compatible or adaptable to existing mechanical interfaces.

Compliance and Status: Active product status and ROHS3 compliance ensure availability and regulatory alignment.

The C&K 8168SHAQE2 is identified as a substitute part based on matching SPDT circuit configuration, momentary operation, panel mount right-angle rear design, PC pin termination, and ROHS3 compliance. However, electrical rating differences exist and must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the APEM 8432WCDB and C&K 8168SHAQE2 maintain active product status and ROHS3 compliance, ensuring regulatory alignment and ongoing availability. Selection between these components depends on application-specific electrical requirements.

The APEM 8432WCDB is specified for 0.4VA at 20V AC/DC operation. The C&K 8168SHAQE2 provides higher electrical ratings (6A at 120V AC, 28V DC), making it suitable for applications requiring greater current capacity and voltage tolerance. The C&K substitute offers extended electrical life (50,000 cycles versus 30,000 cycles) and higher AC voltage capability.

Panel cutout dimensions differ slightly (6.50mm versus 6.35mm), requiring verification of mechanical fit within existing panel interfaces. The APEM part supports a wider operating temperature range (-40°C to 85°C) compared to the C&K substitute (-30°C to 65°C), which may be relevant for extreme environment applications.

Both components share identical circuit topology (SPDT), switch function (momentary), mounting configuration (panel mount right-angle rear), and termination style (PC pin), establishing the foundation for functional substitution within the specified electrical parameters of the target application.

Frequently Asked Questions (FAQ)

Q: Can the C&K 8168SHAQE2 directly replace the APEM 8432WCDB in all applications?

A: Direct replacement is possible only when the application electrical requirements do not exceed the APEM part's ratings (0.4VA at 20V AC/DC). The C&K substitute's higher ratings (6A at 120V AC/DC) make it suitable for higher-power applications. Panel cutout dimension differences (6.50mm versus 6.35mm) must be verified for mechanical compatibility.

Q: What are the key compatibility criteria for substitution?

A: Substitution is based on matching SPDT circuit configuration, momentary operation, panel mount right-angle rear design, PC pin termination, and compliance status. Electrical ratings must meet or exceed application requirements. Mechanical interface dimensions must be compatible with existing panel cutouts.

Q: How do the electrical ratings differ between these parts?

A: The APEM 8432WCDB is rated for 0.4VA at 20V AC/DC. The C&K 8168SHAQE2 is rated for 6A at 120V AC and 28V DC, providing significantly higher current and voltage capacity. Selection depends on whether the application requires the higher ratings or operates within the APEM part's lower specifications.

Q: Are there temperature range considerations for substitution?

A: The APEM 8432WCDB operates from -40°C to 85°C, while the C&K 8168SHAQE2 operates from -30°C to 65°C. For applications requiring operation below -30°C or above 65°C, the APEM part is the appropriate choice.

Q: What is the significance of the panel cutout dimension difference?

A: The APEM part requires a 6.50mm circular cutout, while the C&K substitute requires 6.35mm. This 0.15mm difference is minor but must be verified during mechanical integration to ensure proper panel fit and switch alignment.

Q: Do both parts meet current compliance requirements?

A: Yes, both the APEM 8432WCDB and C&K 8168SHAQE2 are ROHS3 compliant and maintain active product status, ensuring regulatory alignment and ongoing manufacturer support.
