B13KH-AA Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The B13KH-AA is an NKK Switches toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 0.4VA at 28V AC/DC. This through-hole, right-angle mounted switch features a snap-on paddle actuator and is designed for on-off-on switching applications. The part is currently active in production with 754 units in stock. Substitute parts may be required due to inventory constraints, design revisions, or regional availability considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the B13KH-AA is determined by the following critical parameters:

• Circuit Configuration: Must be SPDT to maintain functional equivalence
• Switch Function: Must support On-Off-On operation
• 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, Right Angle to ensure PCB compatibility
• Termination Style: Must use PC Pin termination for direct connection compatibility
• Operating Temperature: Must cover the -30°C to 85°C range
• RoHS Compliance: Must maintain ROHS3 compliance for regulatory alignment

The C&K T103MH9ABE qualifies as a substitute based on matching circuit configuration (SPDT), switch function (On-Off-On), current rating (0.4VA AC/DC), mounting type (Through Hole, Right Angle), termination style (PC Pin), operating temperature range (-30°C to 85°C), and RoHS3 compliance. However, the voltage rating differential requires engineering evaluation.

Parameter Comparison

Engineering Selection Recommendations

Both the B13KH-AA and T103MH9ABE maintain active product status and ROHS3 compliance. The primary differentiation factor is voltage rating: the B13KH-AA is rated for 28V AC/DC, while the T103MH9ABE is rated for 20V AC/DC. Applications operating at or below 20V AC/DC may use the T103MH9ABE as a direct substitute. Applications requiring 28V operation must use the B13KH-AA. The B13KH-AA also provides extended electrical life (50,000 cycles versus 30,000 cycles), which may be relevant for high-cycle applications.

Frequently Asked Questions (FAQ)

Q: Can the T103MH9ABE replace the B13KH-AA in a 28V circuit? A: No. The T103MH9ABE is rated for maximum 20V AC/DC. Using it in a 28V circuit exceeds its voltage specification and may result in component failure or safety hazards.

Q: Are the physical dimensions compatible between these parts? A: Both parts feature Through Hole, Right Angle mounting with PC Pin termination. However, the B13KH-AA has a 9.40mm snap-on paddle actuator, while the T103MH9ABE has a 5.33mm standard round actuator. Panel cutout compatibility should be verified for your specific application.

Q: Do both parts meet the same compliance standards? A: Yes. Both the B13KH-AA and T103MH9ABE are ROHS3 compliant and carry EAR99 ECCN classification. The T103MH9ABE is REACH Affected, while the B13KH-AA is REACH Unaffected.

Q: What is the difference in electrical life between these parts? A: The B13KH-AA is rated for 50,000 switching cycles, while the T103MH9ABE is rated for 30,000 cycles. For applications requiring extended operational life, the B13KH-AA provides a higher cycle rating.

Q: Can I use the T103MH9ABE in applications rated for 20V or lower? A: Yes. The T103MH9ABE is a suitable substitute for the B13KH-AA in applications operating at 20V AC/DC or below, provided all other functional requirements (SPDT circuit, On-Off-On function, 0.4VA current rating, Through Hole Right Angle mounting, and PC Pin termination) are met.
