B23AP-GA Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The B23AP-GA is an NKK Switches toggle switch with DPDT (Double Pole Double Throw) circuit configuration, rated for 0.4VA at 28V AC/DC. This through-hole mounted switch features a standard round actuator with 10.00mm length and non-illuminated design. The product is Active status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical and mechanical parameters align within acceptable tolerances for the application requirements.

Key Parameters

Substitute Part Grouping Explanation

The T203SH9CQE from C&K is identified as a substitute based on the following alignment criteria:

Matching Parameters:

• Circuit configuration: DPDT
• Switch function: On-Off-On
• Mounting type: Through Hole
• Termination style: PC Pin
• Operating temperature range: -30°C to 85°C
• RoHS compliance: ROHS3 Compliant
• Voltage rating - DC: 28V

Substitution Logic: The T203SH9CQE maintains electrical compatibility through identical circuit topology and DC voltage rating. Both switches operate within the same temperature envelope and share through-hole mounting architecture with PC pin termination. The substitute part meets the same regulatory compliance standards (ROHS3).

Engineering Selection Recommendations

B23AP-GA Selection Criteria:

• Primary choice when 50,000 cycle electrical life requirement is specified
• Preferred for applications requiring NKK Switches product line continuity
• Active product status ensures ongoing availability and supply chain stability

T203SH9CQE Selection Criteria:

• Acceptable substitute when higher current capacity (2A vs 0.4VA) provides design margin
• Higher AC voltage rating (120V vs 28V) supports broader application flexibility
• ROHS3 compliance and Active product status maintain regulatory alignment
• Slightly shorter actuator length (9.40mm vs 10.00mm) requires mechanical fit verification in panel cutout design

Both parts maintain ROHS3 compliance and Active product status, ensuring regulatory conformance and supply availability.

Frequently Asked Questions (FAQ)

Q: Can T203SH9CQE replace B23AP-GA in all applications? A: The T203SH9CQE is electrically compatible for DC 28V circuits with DPDT On-Off-On switching function. The substitute part's higher current rating (2A) and AC voltage rating (120V) do not restrict operation at the original part's specifications. Mechanical fit must be verified due to 0.60mm actuator length difference.

Q: What are the key compatibility parameters for DPDT toggle switch substitution? A: Circuit configuration (DPDT), switch function (On-Off-On), DC voltage rating (28V minimum), mounting type (Through Hole), and termination style (PC Pin) are the primary parameters determining substitution viability. Operating temperature range and RoHS compliance status provide secondary validation.

Q: How do electrical life ratings affect substitution decisions? A: The B23AP-GA specifies 50,000 cycles while T203SH9CQE specifies 30,000 cycles. Applications with cycle count requirements exceeding 30,000 operations require the original part. Applications within 30,000 cycle envelope accept the substitute.

Q: Are there packaging differences between these parts? A: B23AP-GA is supplied in Bulk packaging while T203SH9CQE is supplied in Tray packaging. Packaging format does not affect electrical or mechanical compatibility; selection depends on procurement and inventory management requirements.

Q: What mechanical considerations apply to the actuator length difference? A: The 0.60mm actuator length difference (B23AP-GA 10.00mm vs T203SH9CQE 9.40mm) requires verification against panel cutout and mechanical assembly specifications. Both parts use Standard Round actuator type with unthreaded bushing, maintaining consistent mounting interface.
