Key Parameters

Substitute Part Grouping Explanation

Substitution of the M2015SD4G02 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom)
• Current rating (0.4VA AC/DC)
• Voltage rating (28V AC and 28V DC)

Mechanical Compatibility Parameters:

• Mounting type (Panel Mount)
• Actuator type (Standard Round)
• Actuator length (10.50mm)
• Panel cutout dimensions (Circular - 6.50mm Dia)

Environmental & Compliance Parameters:

• Operating temperature range (-30°C to 85°C)
• Electrical life (50,000 Cycles)
• RoHS compliance status

The M2015SD1G01 qualifies as a direct substitute based on identical electrical specifications, mechanical form factor, and environmental ratings. Differences in termination style (Solder Lug versus Quick Connect) and bushing thread specification represent the only variations and do not affect functional equivalence when proper installation procedures are followed.

Parameter Comparison

Engineering Selection Recommendations

The M2015SD1G01 is the manufacturer-recommended substitute for the obsolete M2015SD4G02. Both components maintain identical electrical performance specifications, mechanical form factors, and environmental operating parameters. The substitute part carries active product status, ensuring continued availability and supply chain support.

Selection of the M2015SD1G01 is appropriate for applications requiring:

• SPDT toggle switch functionality with On-Mom operation
• 0.4VA current capacity at 28V AC/DC
• Panel mount installation with 6.50mm circular cutout
• Operating conditions within -30°C to 85°C range
• RoHS compliance certification

The primary distinction between the main part and substitute involves termination methodology and bushing thread specification. The M2015SD1G01 employs solder lug termination in place of quick connect terminals and utilizes 1/4-40 bushing thread instead of M6 x 0.75. These differences require corresponding modifications to circuit board layout and panel mounting hardware but do not affect electrical or functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can the M2015SD1G01 directly replace the M2015SD4G02 without circuit board modifications?

A: The M2015SD1G01 provides electrical and functional equivalence. However, termination style differs: the substitute uses solder lug connections rather than quick connect terminals. Circuit board layout modifications are necessary to accommodate solder lug termination. Panel mounting hardware adjustment is also required due to bushing thread specification differences (1/4-40 versus M6 x 0.75).

Q: Are the electrical ratings identical between these two parts?

A: Yes. Both components are rated for 0.4VA at 28V AC/DC, feature SPDT circuitry with On-Mom operation, and support 50,000 electrical life cycles. Voltage and current specifications are fully equivalent.

Q: What is the significance of the different bushing thread specifications?

A: The M2015SD4G02 uses M6 x 0.75 metric threading, while the M2015SD1G01 uses 1/4-40 UNC threading. Panel cutout dimensions remain identical (6.50mm circular), but the mounting hardware and fastening method differ. Appropriate bushings and fasteners for the selected thread specification must be used during installation.

Q: Does the termination style change affect the switch's performance characteristics?

A: No. Both quick connect and solder lug termination styles provide equivalent electrical connection. The choice between termination methods is determined by circuit board design and assembly process requirements, not by performance or reliability considerations.

Q: Is the M2015SD1G01 RoHS compliant?

A: Yes. The M2015SD1G01 maintains RoHS compliance status identical to the M2015SD4G02, ensuring compatibility with regulatory requirements and environmental standards.

Q: What is the inventory status of the substitute part?

A: The M2015SD1G01 is classified as active product status with 764 units in stock, providing reliable supply availability compared to the obsolete M2015SD4G02.
