M2012TXG13-DC Equivalent & Substitute Parts

Part Overview

The M2012TXG13-DC is a rocker switch manufactured by NKK Switches, classified as SPDT (Single Pole Double Throw) with a current rating of 0.4VA at 28V AC/DC. This through-hole mounted switch features a concave red actuator with epoxy sealed PC pin termination. The product is currently obsolete, with 720 units available in new original stock. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary for ongoing design requirements and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2012TXG13-DC is determined by the following critical parameters: circuit configuration (SPDT), switch function (On-On), mounting type (Through Hole), termination style (PC Pin), actuator type (Concave), and voltage/current ratings. Substitute parts must maintain compatibility with these core electrical and mechanical specifications.

The identified substitute parts are grouped as follows:

MFR Recommended Equivalent: MN12TXG13-DC (NKK Switches) — Same manufacturer, miniature PC mount variant with active product status.

Similar Functional Equivalents: 7101J1V3BE3 (C&K) and B123J71V3Q3 (Electroswitch) — Both maintain SPDT circuit configuration, On-On function, through-hole mounting, PC pin termination, concave red actuator, and compatible operating temperature range. Voltage and current ratings differ within acceptable substitution parameters.

Parameter Comparison

Engineering Selection Recommendations

MN12TXG13-DC (NKK Switches): This part is the preferred equivalent, manufactured by the same supplier as the original M2012TXG13-DC. Active product status ensures long-term availability and supply chain continuity. Maintains ROHS3 compliance and carries the same regulatory approvals (CSA, UL). Recommended as the primary replacement for direct substitution.

7101J1V3BE3 (C&K): Suitable for applications where voltage requirements do not exceed 20V AC/DC. Provides extended electrical life (100,000 cycles versus 50,000 cycles). Maintains ROHS3 compliance with cULus certification. Appropriate for designs with lower voltage specifications.

B123J71V3Q3 (Electroswitch): Applicable for higher current applications requiring up to 6A at 125V AC. Maintains CSA and UL approvals consistent with the original part. Electrical life of 60,000 cycles exceeds the original specification. Suitable for designs with elevated power requirements.

Frequently Asked Questions (FAQ)

Q: Can MN12TXG13-DC directly replace M2012TXG13-DC in existing designs?

A: MN12TXG13-DC is manufactured by NKK Switches and shares the same base product number (MN12TX versus M2012TX). However, specific electrical and mechanical parameters are not fully documented for MN12TXG13-DC. Physical verification of mounting dimensions and electrical characteristics is necessary before implementation.

Q: What are the voltage limitations when substituting with 7101J1V3BE3?

A: The 7101J1V3BE3 is rated for 20V AC/DC, which is lower than the original M2012TXG13-DC specification of 28V. This substitute is suitable only for applications operating at 20V or below. Applications requiring 28V operation must use alternative parts.

Q: Is B123J71V3Q3 suitable for low-power applications matching the original 0.4VA specification?

A: Yes. The B123J71V3Q3 is rated for 6A at 125V AC, which exceeds the original 0.4VA requirement. It is electrically compatible with lower-power circuits and can be used in applications requiring the original 0.4VA specification. The higher current rating provides design margin without adverse effects on low-power operation.

Q: What compliance certifications should be verified for substitute parts?

A: The original M2012TXG13-DC carries CSA and UL approvals. MN12TXG13-DC maintains these certifications. The 7101J1V3BE3 carries cULus certification. The B123J71V3Q3 carries CSA and UL approvals. Verify that the selected substitute meets the regulatory requirements of your application and target market.

Q: Are all substitute parts ROHS3 compliant?

A: MN12TXG13-DC and 7101J1V3BE3 are explicitly ROHS3 compliant. B123J71V3Q3 is RoHS compliant. Confirm specific ROHS revision requirements for your application before final selection.

Q: What is the difference in mechanical life between the original and substitute parts?

A: The original M2012TXG13-DC specifies 50,000 mechanical cycles. MN12TXG13-DC does not provide this specification. The 7101J1V3BE3 does not specify mechanical life but provides 100,000 electrical cycles. The B123J71V3Q3 does not specify mechanical life but provides 60,000 electrical cycles. For applications with high cycle count requirements, the 7101J1V3BE3 offers the highest documented electrical life.
