M2012TXW13-DC Rocker Switch SPDT Equivalent & Substitute Parts

Part Overview

The M2012TXW13-DC is an NKK Switches rocker switch with SPDT (Single Pole Double Throw) configuration, rated for 6A AC at 125V and 4A DC at 30V. This through-hole mounted component features a red concave actuator with epoxy sealed PC pin terminals and is designed for On-On switching applications. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing maintenance, repair, and new design implementations where functional compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2012TXW13-DC is determined by the following critical parameters:

Primary Substitution Criteria:

• Circuit configuration (SPDT required)
• Switch function (On-On operation)
• Current and voltage ratings (must meet or exceed AC 6A/125V and DC 4A/30V)
• Mounting type (through-hole compatibility)
• Actuator type and color (concave, red)
• Termination style (PC pin)
• Operating temperature range (-30°C to 85°C minimum)

Compliance Considerations:

• RoHS3 compliance status
• Regulatory approvals (CSA, UL preferred)

The substitute parts identified are grouped based on their ability to satisfy these electrical and mechanical parameters within the constraints of available product specifications.

Parameter Comparison

Engineering Selection Recommendations

B123J71V3Q3 (Electroswitch) is the primary substitute for the M2012TXW13-DC. This part maintains electrical equivalence with identical AC current rating (6A), AC voltage rating (125V), and nearly equivalent DC voltage rating (28V versus 30V). Both components share SPDT configuration, On-On function, through-hole mounting, concave red actuator, PC pin termination, and identical operating temperature range. The B123J71V3Q3 is currently active in production, holds CSA and UL approvals matching the original part, and provides superior electrical life (60,000 cycles versus 25,000 cycles). RoHS compliance is confirmed for both parts.

7101J1V3BE3 (C&K) is a functional substitute with limitations. While it maintains SPDT configuration, On-On function, through-hole mounting, concave red actuator, PC pin termination, and identical operating temperature range, the current and voltage ratings are significantly reduced (0.4VA at 20V AC/DC). This part is suitable only for applications where the original 6A/125V rating is not required. The 7101J1V3BE3 offers extended electrical life (100,000 cycles) and ROHS3 compliance with cULus approval.

MN12TXW13-DC (NKK Switches) is listed as a manufacturer-recommended substitute but lacks sufficient specification data for complete parameter verification. The base product number (MN12TX) suggests a related product line from the same manufacturer. This part is currently active in production. Detailed electrical and mechanical specifications must be obtained from the manufacturer before selection.

Frequently Asked Questions (FAQ)

Q: Can the B123J71V3Q3 directly replace the M2012TXW13-DC in all applications?

A: The B123J71V3Q3 provides direct electrical and mechanical compatibility for applications operating at or below 6A AC and 125V AC. The DC voltage rating of 28V is within 2V of the original 30V specification. Both parts share identical circuit configuration (SPDT), switch function (On-On), mounting type (through-hole), actuator specifications, and termination style. Regulatory approvals (CSA, UL) are equivalent.

Q: What are the limitations of the 7101J1V3BE3 as a substitute?

A: The 7101J1V3BE3 has significantly reduced current and voltage ratings (0.4VA at 20V AC/DC) compared to the M2012TXW13-DC (6A at 125V AC). This part is suitable only for low-power switching applications. It should not be used in circuits designed for the original part's 6A/125V rating. The 7101J1V3BE3 is functionally compatible in terms of circuit configuration, mounting, and actuator type but is electrically limited to lower-power applications.

Q: Why is the MN12TXW13-DC listed as a manufacturer-recommended substitute if specifications are incomplete?

A: The MN12TXW13-DC is identified as a manufacturer-recommended alternative from NKK Switches, the original manufacturer. The incomplete specification data in available documentation does not reflect the actual part capabilities. Contact NKK Switches directly to obtain complete electrical and mechanical specifications before design implementation.

Q: Are all substitute parts RoHS compliant?

A: The B123J71V3Q3 and M2012TXW13-DC are RoHS compliant. The 7101J1V3BE3 is ROHS3 compliant. RoHS compliance status for the MN12TXW13-DC is not specified in available documentation.

Q: What is the impact of electrical life differences between the main part and substitutes?

A: The M2012TXW13-DC has an electrical life of 25,000 cycles. The B123J71V3Q3 provides 60,000 cycles, and the 7101J1V3BE3 provides 100,000 cycles. Higher electrical life ratings indicate longer component durability under switching conditions. For applications requiring extended service life or frequent switching operations, the B123J71V3Q3 or 7101J1V3BE3 offer improved longevity.

Q: Are there packaging differences between the main part and substitutes?

A: The M2012TXW13-DC is supplied in standard packaging. The B123J71V3Q3 and 7101J1V3BE3 are supplied in bulk packaging. The MN12TXW13-DC is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility but may influence procurement quantities and handling procedures.
