Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2012SS1G02 is determined by strict alignment of the following critical parameters:

Electrical Parameters: Circuit configuration (SPDT), switch function (On-On), current rating (0.4VA AC/DC), and voltage ratings (28V AC and DC) must match exactly.

Mechanical Parameters: Mounting type (panel mount), actuator type (standard round), actuator length (10.50mm), panel cutout dimensions (circular 6.50mm diameter), and bushing thread (1/4-40) must be identical.

Environmental Parameters: Operating temperature range (-30°C ~ 85°C) and electrical life (50,000 cycles) must be maintained.

Compliance Parameters: RoHS3 compliance status must be present.

The identified substitute parts meet these criteria with variations only in termination style and product status, which do not affect functional compatibility in applications where the electrical and mechanical interfaces can be adapted.

Parameter Comparison

Engineering Selection Recommendations

M2012SS1G01: This part is manufacturer-recommended and shares identical electrical, mechanical, and environmental specifications with the M2012SS1G02. The primary difference is termination style (solder lug versus quick connect). This substitute is suitable for applications where solder lug termination can be accommodated. Both parts carry obsolete status and ROHS3 compliance.

MN12SS1G02: This part is listed as active product status, providing potential long-term availability advantage over the obsolete M2012SS1G02. However, complete electrical and mechanical parameter specifications are not provided in the available data. Confirmation of full parameter alignment is required before selection for critical applications.

Frequently Asked Questions (FAQ)

Q: Can M2012SS1G01 be used as a direct replacement for M2012SS1G02?

A: M2012SS1G01 matches all critical electrical, mechanical, and environmental parameters. The difference in termination style (solder lug versus quick connect) requires evaluation of the application's connection method. If the circuit board or harness can accommodate solder lug termination, this part is functionally equivalent.

Q: What is the significance of the termination style difference?

A: M2012SS1G02 uses quick connect termination (0.062" / 1.5mm), while M2012SS1G01 uses solder lug termination. Quick connect allows push-on connection to spade terminals, whereas solder lug requires soldering to the circuit. Selection depends on the existing connection infrastructure.

Q: Why is MN12SS1G02 listed as a substitute if specifications are incomplete?

A: MN12SS1G02 is identified as a substitute based on manufacturer documentation. However, incomplete parameter data in the available specifications means full compatibility cannot be confirmed without additional technical documentation. Contact the manufacturer or distributor for complete electrical and mechanical specifications before selection.

Q: Does product status affect functional performance?

A: Product status (obsolete versus active) does not affect electrical or mechanical performance. Active status indicates ongoing manufacturing and availability, while obsolete status indicates discontinued production. For long-term sourcing, active parts may offer supply chain advantages.

Q: Are all substitute parts ROHS3 compliant?

A: M2012SS1G01 is confirmed ROHS3 compliant. MN12SS1G02 compliance status is not specified in available data and should be verified with the manufacturer.
