M2012TYG01-JA Equivalent & Substitute Parts

Part Overview

The M2012TYG01-JA is a rocker switch manufactured by NKK Switches, classified as SPDT (Single Pole Double Throw) with On-On switching function. This panel-mount, flange-style component is rated for 0.4VA at 28V AC/DC operation with solder lug termination and epoxy sealed terminals. The product is currently obsolete, making identification of equivalent and substitute parts essential for system maintenance, repair, and redesign applications where this component is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the M2012TYG01-JA is determined by the following critical parameters:

Primary Substitution Criteria:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Mounting type (Panel Mount, Flange)
• Termination style (Solder Lug)
• Voltage and current ratings compatibility
• Panel cutout dimensions (mechanical fit)
• Operating temperature range
• Regulatory approvals (CSA, UL)

Substitute Categories:

MFR Recommended Substitute: MN12TYG01-JA (NKK Switches) — Direct manufacturer alternative within the same product family, representing the active-status equivalent to the obsolete M2012TYG01-JA.

Similar Substitute: B123J3ZQ2 (Electroswitch) — Cross-manufacturer alternative with matching SPDT circuit, On-On function, panel-mount flange configuration, solder lug termination, and compatible mechanical dimensions. Electrical ratings differ (6A at 125V AC vs. 0.4VA at 28V), making this suitable only for applications where higher current and voltage capacity are acceptable or required.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): Select MN12TYG01-JA when the primary objective is to maintain functional and mechanical compatibility with the original M2012TYG01-JA specification. This NKK Switches part carries active product status, ensuring long-term availability and supply chain stability. Both parts share the same manufacturer lineage and base product number (M/MN12TY series), supporting design continuity.

For Cross-Manufacturer Substitution: Select B123J3ZQ2 when system requirements permit higher electrical ratings (6A at 125V AC) or when supply constraints necessitate an alternative source. This Electroswitch component maintains SPDT circuit topology, On-On switching function, panel-mount flange configuration, and solder lug termination. Panel cutout dimensions differ marginally (27.81mm x 16.46mm vs. 28.50mm x 16.00mm), requiring mechanical fit verification. Both parts carry CSA and UL approvals and operate within the same temperature range (-30°C to 85°C).

Compliance Considerations: All three parts maintain regulatory compliance (CSA, UL approvals). The M2012TYG01-JA and B123J3ZQ2 are ROHS3 and RoHS compliant respectively. MN12TYG01-JA compliance status is not specified in available documentation.

Frequently Asked Questions (FAQ)

Q: Can MN12TYG01-JA be used as a direct replacement for M2012TYG01-JA? A: MN12TYG01-JA is the manufacturer-recommended equivalent. Both are NKK Switches products within the same M/MN12TY series. However, detailed electrical and mechanical specifications for MN12TYG01-JA are not fully documented in available data. Confirmation with the manufacturer or component datasheet is necessary to ensure complete parameter alignment.

Q: What are the mechanical compatibility considerations for B123J3ZQ2? A: Panel cutout dimensions differ slightly: B123J3ZQ2 requires 27.81mm x 16.46mm versus 28.50mm x 16.00mm for M2012TYG01-JA. This 0.69mm width reduction and 0.46mm height increase may require panel modification or mechanical fit assessment depending on tolerance specifications in the original design.

Q: Can B123J3ZQ2 be used in applications originally specified for M2012TYG01-JA? A: B123J3ZQ2 is electrically rated higher (6A at 125V AC versus 0.4VA at 28V). It maintains SPDT circuit topology, On-On function, panel-mount flange configuration, and solder lug termination. Substitution is feasible for applications where higher electrical capacity is acceptable. DC voltage rating matches at 28V. Mechanical fit and panel cutout dimensions require verification.

Q: What is the difference between MFR Recommended and Similar substitutes? A: MFR Recommended (MN12TYG01-JA) is the manufacturer's direct alternative to the obsolete M2012TYG01-JA, ensuring design continuity within the same product family. Similar (B123J3ZQ2) is a cross-manufacturer alternative that matches functional and mechanical characteristics but originates from a different manufacturer (Electroswitch) and carries higher electrical ratings.

Q: Are all substitute parts RoHS compliant? A: M2012TYG01-JA is ROHS3 compliant. B123J3ZQ2 is RoHS compliant. MN12TYG01-JA compliance status is not specified in available documentation.

Q: What certifications do these parts carry? A: M2012TYG01-JA and B123J3ZQ2 both carry CSA and UL approvals. MN12TYG01-JA certification status is not specified in available documentation.
