A23AP-GA Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The A23AP-GA is an active production toggle switch manufactured by NKK Switches, configured as a Double Pole Double Throw (DPDT) switch with On-Off-On functionality. This through-hole mounted component is rated for 0.4VA at 28V AC/DC operation with a standard round actuator and polyamide construction. The part is stocked with 698 units in inventory and maintains ROHS3 compliance with unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified to support design flexibility, inventory optimization, and supply chain continuity when the primary part becomes unavailable or when application requirements permit alternative specifications within acceptable electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A23AP-GA is determined by the following critical parameters:

• Circuit Configuration: Must be DPDT to maintain electrical functionality
• Switch Function: Must be On-Off-On to preserve operational behavior
• Current Rating: Must support minimum 0.4VA (AC/DC)
• Voltage Rating: Must support minimum 28V AC and 28V DC
• Mounting Type: Must be Through Hole for PCB compatibility
• Termination Style: Must be PC Pin for connection compatibility
• Operating Temperature Range: Must encompass -30°C to 85°C
• RoHS Compliance: Must maintain ROHS3 compliance status

The ET23SD1CBE from C&K meets these substitution criteria with the following considerations: voltage rating is 20V (lower than the 28V specification), electrical life is 30,000 cycles (lower than 50,000 cycles), and actuator length is 10.16mm (marginally different from 10.00mm). These variations remain within acceptable tolerance for equivalent part classification based on the provided electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the A23AP-GA and ET23SD1CBE maintain active production status and ROHS3 compliance, supporting long-term supply chain viability. The A23AP-GA provides higher voltage rating (28V versus 20V) and extended electrical life (50,000 versus 30,000 cycles), making it suitable for applications requiring maximum operational longevity and higher voltage tolerance. The ET23SD1CBE offers IP57 ingress protection, providing enhanced environmental sealing for applications exposed to dust and moisture conditions.

Selection between these parts should be based on specific application voltage requirements and environmental exposure conditions. Applications operating at or below 20V with environmental protection requirements may utilize the ET23SD1CBE. Applications requiring 28V operation or extended cycle life should specify the A23AP-GA.

Frequently Asked Questions (FAQ)

Q: Can the ET23SD1CBE replace the A23AP-GA in all applications?

A: The ET23SD1CBE is electrically compatible for applications operating at 20V or below. Applications requiring 28V operation must use the A23AP-GA, as the ET23SD1CBE voltage rating is insufficient for higher voltage circuits.

Q: What is the significance of the 20,000-cycle difference in electrical life?

A: The A23AP-GA supports 50,000 switching cycles while the ET23SD1CBE supports 30,000 cycles. Applications with high switching frequency or extended operational life requirements should specify the A23AP-GA to ensure adequate component longevity.

Q: Are there mechanical compatibility concerns between these parts?

A: Both parts use Through Hole mounting with PC Pin termination and standard round actuators. The actuator length difference (10.00mm versus 10.16mm) is 0.16mm and falls within typical mechanical tolerance for panel-mounted applications. Panel cutout dimensions should be verified for specific mechanical fit requirements.

Q: Does the IP57 rating of the ET23SD1CBE provide additional functionality?

A: The IP57 ingress protection rating indicates dust protection and waterproof sealing. This specification applies only to the ET23SD1CBE and should be considered when environmental exposure is a design requirement. The A23AP-GA does not specify ingress protection.

Q: Are both parts suitable for the same PCB assembly process?

A: Yes. Both parts use identical Through Hole mounting type and PC Pin termination style, supporting standard PCB assembly processes without modification.

Q: What compliance certifications apply to both parts?

A: Both the A23AP-GA and ET23SD1CBE maintain ROHS3 compliance and are classified as EAR99 for export control purposes. Both parts carry HTSUS code 8536.50.9065 for tariff classification.
