NKK Switches B13HH Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The NKK Switches B13HH is an active-status toggle switch featuring SPDT (Single Pole Double Throw) circuitry with On-Off-On switching function. This through-hole, right-angle mounted component is rated for 0.4VA at 28V AC/DC operation across a temperature range of -30°C to 85°C. The B13HH is specified with epoxy sealed terminals and a flatted brass nickel-plated actuator measuring 6.30mm in length. Finding equivalent substitute parts becomes necessary when managing inventory constraints, lead time requirements, or when sourcing from alternative manufacturers while maintaining functional and electrical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the B13HH is determined by strict alignment with the following critical parameters:

• Circuit Configuration: Must be SPDT
• Switch Function: Must be On-Off-On
• Current Rating: Must be 0.4VA (AC/DC)
• Voltage Rating - AC: Must be rated for minimum 28V AC
• Voltage Rating - DC: Must be rated for minimum 28V DC
• Mounting Type: Must be Through Hole, Right Angle
• Termination Style: Must be PC Pin
• Operating Temperature Range: Must encompass -30°C to 85°C
• Electrical Life: Must meet or exceed 50,000 cycles
• RoHS Status: Must be ROHS3 Compliant

The E-Switch 200AWMSP3T2A1M6RE qualifies as a substitute part. However, the voltage rating differential (20V versus 28V) represents a critical design consideration that must be evaluated within the specific application context.

Parameter Comparison

Engineering Selection Recommendations

Both the NKK Switches B13HH and E-Switch 200AWMSP3T2A1M6RE maintain active product status and ROHS3 compliance. The primary differentiation factor is the voltage rating specification: the B13HH is rated for 28V AC/DC operation, while the 200AWMSP3T2A1M6RE is rated for 20V AC/DC operation. Applications operating at or above 20V and below or equal to 28V may utilize either part. Applications requiring operation above 20V but below 28V require confirmation that the 200AWMSP3T2A1M6RE meets the specific voltage threshold of the design. The E-Switch substitute provides additional ingress protection (IP67) not specified in the B13HH datasheet.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 200AWMSP3T2A1M6RE replace the NKK Switches B13HH in all applications?

A: Substitution is valid for applications operating within the 200AWMSP3T2A1M6RE voltage specification of 20V AC/DC. Applications requiring operation above 20V require design verification that the substitute part meets the application voltage threshold.

Q: What is the primary difference between these two parts?

A: The voltage rating is the primary specification difference. The B13HH is rated for 28V AC/DC, while the 200AWMSP3T2A1M6RE is rated for 20V AC/DC. Both parts share identical circuit configuration (SPDT), switch function (On-Off-On), current rating (0.4VA), mounting type (Through Hole, Right Angle), and electrical life (50,000 cycles).

Q: Are both parts RoHS compliant?

A: Yes, both the B13HH and 200AWMSP3T2A1M6RE are ROHS3 compliant.

Q: What is the actuator length difference?

A: The B13HH features a 6.30mm flatted actuator, while the 200AWMSP3T2A1M6RE features a 6.10mm standard round actuator. This 0.20mm difference may impact panel cutout and mechanical fit considerations.

Q: Does the E-Switch part offer any additional features?

A: The 200AWMSP3T2A1M6RE includes IP67 ingress protection (dust tight, waterproof), which is not specified for the B13HH. This additional protection may be beneficial in harsh environmental applications.
