M2021B2B3W02-VC Equivalent & Substitute Parts

Part Overview

The M2021B2B3W02-VC is a miniature toggle switch manufactured by NKK Switches, configured as a DPST (Double Pole Single Throw) panel mount component with a bushing mount design. This switch is rated for 6A AC at 125V and 4A DC at 30V, featuring a non-illuminated standard round actuator with red cap and IP67 ingress protection. The part is currently classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the M2021B2B3W02-VC is determined by strict equivalence across the following critical parameters: circuit configuration (DPST), current and voltage ratings (6A AC/125V, 4A DC/30V), mounting methodology (panel mount with M12 x 1 bushing thread), mechanical interface (12.50mm circular cutout, 17.50mm actuator length), environmental protection (IP67), and operating temperature range (-30°C to 85°C). The M2021B2B3W01-VC maintains all these core electrical and mechanical specifications while differing only in termination style (Solder Lug versus Quick Connect) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The M2021B2B3W01-VC is a direct functional equivalent to the M2021B2B3W02-VC for applications requiring DPST panel mount toggle switches with identical electrical ratings and mechanical interfaces. The substitute part carries Active product status, ensuring continued availability and manufacturing support. Both parts maintain RoHS compliance and equivalent environmental specifications. Selection between these parts depends solely on termination methodology: the M2021B2B3W01-VC employs solder lug termination, while the M2021B2B3W02-VC uses quick connect termination. Circuit board design and assembly process requirements determine the appropriate termination style for each application.

Frequently Asked Questions (FAQ)

Q: Can the M2021B2B3W01-VC replace the M2021B2B3W02-VC in existing designs?

A: Yes, provided the circuit board accommodates solder lug termination instead of quick connect termination. All electrical ratings, mechanical dimensions, and environmental specifications are identical.

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

A: The termination style differs. The M2021B2B3W02-VC features quick connect terminals (0.062" / 1.5mm), while the M2021B2B3W01-VC uses solder lug termination. Both maintain identical DPST functionality, current/voltage ratings, and panel mount configuration.

Q: Are there any compliance differences between the substitute and the original part?

A: Both parts are RoHS compliant. The main part carries RoHS3 certification, while the substitute carries RoHS certification. Both meet environmental and regulatory requirements for their respective product statuses.

Q: Does the M12 x 1 bushing thread remain the same for both parts?

A: Yes. Both parts use M12 x 1 bushing thread and require a 12.50mm circular panel cutout. Mechanical installation is identical.

Q: What is the significance of the Active versus Obsolete product status?

A: The M2021B2B3W01-VC maintains Active status, indicating current manufacturing and availability. The M2021B2B3W02-VC is Obsolete, making the substitute the recommended choice for new designs and ongoing production requirements.
