B22JH-JC Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The B22JH-JC is an NKK Switches toggle switch with DPDT (Double Pole Double Throw) configuration, rated for 0.4VA at 28V AC/DC. This through-hole, right-angle mounted switch features a standard round actuator with red cap and is designed for applications requiring reliable switching in the specified voltage and current range. The part is Active status and ROHS3 compliant, making it suitable for modern electronic assemblies. Substitute parts may be required due to inventory constraints, design revisions, or application-specific performance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the B22JH-JC is determined by the following critical parameters:

• Circuit Configuration: Must be DPDT to maintain functional equivalence
• Switch Function: Must be On-On to preserve switching behavior
• Mounting Type: Must be Through Hole, Right Angle for PCB compatibility
• Termination Style: Must be PC Pin for direct connection compatibility
• Voltage Rating: Substitute must meet or exceed both AC and DC voltage requirements (28V minimum)
• Current Rating: Substitute must support at least 0.4VA to handle the intended load
• Operating Temperature: Must span -30°C to 85°C range
• RoHS Compliance: Must maintain ROHS3 compliance for regulatory alignment

Two substitute parts meet these criteria: the E-Switch 200AWMDP1T2A1M6QE and the C&K ET21MD1ABE. Both are DPDT toggle switches with through-hole, right-angle mounting and PC pin termination. The E-Switch part exceeds voltage and current specifications, while the C&K part matches the current rating with slightly lower voltage specifications that remain within acceptable operating parameters.

Parameter Comparison

Engineering Selection Recommendations

E-Switch 200AWMDP1T2A1M6QE: This substitute provides enhanced electrical performance with 3A current capacity and 120V AC rating, exceeding the B22JH-JC specifications. It maintains DC voltage compatibility at 28V and includes IP67 ingress protection with epoxy sealed terminals. ROHS3 compliance is confirmed. This part is suitable for applications requiring higher current handling or enhanced environmental protection.

C&K ET21MD1ABE: This substitute matches the current rating of the B22JH-JC at 0.4VA but operates at reduced voltage specifications (20V AC/DC). It provides extended electrical life at 60,000 cycles and includes IP57 ingress protection with epoxy sealed terminals. ROHS3 compliance is confirmed. This part is suitable for applications where voltage requirements do not exceed 20V and enhanced environmental sealing is beneficial.

Selection between substitutes depends on application voltage requirements and environmental conditions. The E-Switch part accommodates higher voltage applications, while the C&K part offers improved environmental protection and extended cycle life within lower voltage constraints.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 200AWMDP1T2A1M6QE replace the B22JH-JC in all applications?

A: The E-Switch part is electrically compatible with the B22JH-JC for applications operating at 28V or below. The higher current rating (3A vs. 0.4VA) and AC voltage rating (120V) provide design margin. Physical dimensions differ slightly (6.10mm vs. 6.30mm actuator length), which may require PCB layout verification.

Q: Can the C&K ET21MD1ABE replace the B22JH-JC in all applications?

A: The C&K part is compatible only for applications operating at 20V or below. The AC voltage rating of 20V is lower than the B22JH-JC specification of 28V. Current rating and switch function are equivalent. Actuator length is 6.10mm versus 6.30mm on the original part.

Q: What are the key differences in environmental protection?

A: The B22JH-JC has no specified ingress protection rating. The E-Switch substitute provides IP67 protection (dust tight, waterproof), while the C&K substitute provides IP57 protection (dust protected, waterproof). Both substitutes feature epoxy sealed terminals for enhanced environmental resistance.

Q: Are all three parts RoHS compliant?

A: Yes, all three parts are ROHS3 compliant. The C&K ET21MD1ABE is REACH Affected, while the B22JH-JC and E-Switch part are REACH Unaffected.

Q: How do electrical life ratings compare?

A: The B22JH-JC and E-Switch part both specify 50,000 cycles. The C&K part specifies 60,000 cycles, providing extended operational life.
