B23AW Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The B23AW is an active NKK Switches toggle switch featuring DPDT (Double Pole Double Throw) circuitry with On-Off-On switching function. Rated for 0.4VA at 28V AC/DC, this through-hole mounted component is designed for applications requiring reliable electromechanical switching with epoxy sealed terminals. The part maintains active product status with 750 units in current inventory. Substitute parts may be required due to supply constraints, design revisions, or application-specific performance requirements while maintaining functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

The T203SH9CQE from C&K qualifies as a functional substitute based on the following critical parameters:

Matching Parameters:

• Circuit configuration: DPDT
• Switch function: On-Off-On
• Mounting type: Through Hole
• Actuator type: Standard Round
• Operating temperature range: -30°C to 85°C
• RoHS3 compliance
• Epoxy sealed terminals
• Product status: Active

Substitution Constraints: Substitution is valid when the application operates within the intersection of both parts' electrical ratings. The T203SH9CQE supports higher current (2A) and AC voltage (120V) ratings compared to the B23AW (0.4VA, 28V AC). Applications designed for B23AW specifications remain compatible with T203SH9CQE. Termination style differs (Wire Wrap vs. PC Pin), requiring board layout verification. Actuator length variance (10.00mm vs. 9.40mm) and electrical life difference (50,000 vs. 30,000 cycles) must be evaluated for specific mechanical and durability requirements.

Parameter Comparison

Engineering Selection Recommendations

Both B23AW and T203SH9CQE maintain active product status with ROHS3 compliance, supporting long-term design viability. Selection between these parts depends on application-specific requirements:

Select B23AW when:

• Wire Wrap termination is required for existing board designs
• Electrical life requirement exceeds 30,000 cycles
• Actuator length of 10.00mm is mechanically specified

Select T203SH9CQE when:

• PC Pin termination is compatible with board layout
• Application operates within 30,000 cycle electrical life specification
• Higher current or voltage headroom is beneficial for design margin
• C&K component availability or supply chain preference exists

Both parts satisfy the core functional requirements of DPDT On-Off-On switching at 28V DC operation with identical operating temperature ranges and RoHS compliance status.

Frequently Asked Questions (FAQ)

Q: Can T203SH9CQE directly replace B23AW in existing designs?

A: Functional substitution is possible if the application operates within both parts' electrical ratings (0.4VA maximum for B23AW specifications). However, termination style differs (Wire Wrap vs. PC Pin), requiring PCB layout verification. Actuator length variance (0.60mm) must be confirmed against mechanical constraints.

Q: What is the primary difference in electrical ratings?

A: T203SH9CQE is rated for 2A at 120V AC, while B23AW is rated for 0.4VA at 28V AC/DC. Applications designed for B23AW specifications operate safely with T203SH9CQE. The substitute part provides higher electrical headroom.

Q: How do termination styles affect substitution?

A: B23AW uses Wire Wrap termination; T203SH9CQE uses PC Pin termination. These require different board footprints and soldering approaches. Verify PCB design compatibility before substitution.

Q: Does electrical life difference impact substitution suitability?

A: B23AW is rated for 50,000 cycles; T203SH9CQE for 30,000 cycles. For applications with duty cycles below 30,000 cycles, both parts are equivalent. High-cycle applications should prioritize B23AW or confirm T203SH9CQE meets specific cycle requirements.

Q: Are both parts currently available?

A: Yes. B23AW has 750 units in inventory; T203SH9CQE has 1,033 units in inventory. Both maintain active product status.

Q: What packaging differences exist?

A: B23AW is supplied in Bulk packaging; T203SH9CQE in Tray packaging. Verify packaging compatibility with receiving and assembly processes.
