B13KV Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The B13KV is an NKK Switches toggle switch featuring SPDT (Single Pole Double Throw) circuit configuration with 0.4VA current rating at 28V. This through-hole, right-angle mounted component operates across -30°C to 85°C with 50,000 electrical cycles. The part is actively produced and ROHS3 compliant, making it suitable for industrial control applications requiring reliable on-off-on switching functionality.

Substitute parts become necessary when the primary part faces supply constraints, extended lead times, or when design requirements permit operation at lower voltage ratings while maintaining equivalent switching performance.

Key Parameters

Substitute Part Grouping Explanation

The T103MH9AVBE from C&K qualifies as a functional substitute based on the following alignment of critical parameters:

Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-Off-On
• Current rating: 0.4VA (AC/DC)
• Mounting type: Through Hole, Right Angle, Vertical
• Termination style: PC Pin
• Operating temperature range: -30°C to 85°C
• RoHS3 compliance
• Active product status

Differing Parameters:

• Voltage rating: 20V (AC/DC) versus 28V on B13KV
• Electrical life: 30,000 cycles versus 50,000 cycles
• Actuator type: Standard Round versus Lever for Cap
• Actuator length: 5.33mm versus 5.00mm
• Packaging: Tray versus Bulk

Substitution is valid when the application voltage requirement does not exceed 20V and the design can accommodate 30,000 electrical cycles minimum.

Parameter Comparison

Engineering Selection Recommendations

Both B13KV and T103MH9AVBE maintain active production status and ROHS3 compliance, ensuring regulatory alignment for current designs. Selection between these parts depends on application voltage requirements and cycle life expectations.

The B13KV is the primary choice for applications operating at 28V or requiring extended electrical life beyond 30,000 cycles. The T103MH9AVBE serves as a viable alternative for systems operating at 20V or lower, provided the design cycle life requirement does not exceed 30,000 operations. Both parts share identical current ratings, mounting configurations, and temperature operating ranges, supporting direct mechanical and electrical substitution within voltage constraints.

Frequently Asked Questions (FAQ)

Q: Can T103MH9AVBE replace B13KV in a 28V circuit? A: No. The T103MH9AVBE is rated for 20V maximum. Using it in a 28V application exceeds its voltage specification and creates reliability risk.

Q: What is the primary difference between these switches? A: Voltage rating and electrical life cycle count. B13KV operates at 28V with 50,000 cycles; T103MH9AVBE operates at 20V with 30,000 cycles.

Q: Are the physical dimensions compatible? A: Both use through-hole, right-angle vertical mounting with PC pin termination. Actuator length differs slightly (5.00mm versus 5.33mm), which may affect panel cutout alignment in space-constrained designs.

Q: Do both parts meet RoHS requirements? A: Yes. Both B13KV and T103MH9AVBE are ROHS3 compliant.

Q: Which part should I specify for new designs? A: Specify B13KV for 28V applications or when electrical life exceeding 30,000 cycles is required. Specify T103MH9AVBE only when application voltage is confirmed at 20V or lower and cycle life requirements do not exceed 30,000 operations.

Q: Does packaging format affect electrical performance? A: No. B13KV bulk packaging and T103MH9AVBE tray packaging do not affect electrical characteristics or switching performance.
