SB285-015H Equivalent & Substitute Parts

Part Overview

The SB285-015H is a pushbutton switch manufactured by NKK Switches, featuring a DPDT (Double Pole Double Throw) circuit configuration with On-On switching function. This component is rated for 6A at 125V AC and is designed for panel mount, rear installation with a circular 12.50mm diameter cutout. The product is classified as obsolete, making identification of equivalent substitute parts essential for ongoing maintenance, repair, and design continuity in applications where this switch was originally specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SB285-015H is determined by strict adherence to the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit Configuration: DPDT (Double Pole Double Throw)
• Switch Function: On-On
• Voltage Rating: 125V AC minimum
• Mounting Type: Panel Mount, Rear
• Panel Cutout Dimensions: Circular 12.50mm diameter
• Actuator Type: Round, Plunger, Metal
• Termination Style: Solder Lug

Allowable Variation:

• Current Rating: The substitute part may have a higher current rating than the original 6A specification, provided all other parameters remain identical. A higher current rating does not compromise compatibility and may provide enhanced capability for the application.

The substitute part SB25-015H/UC meets all mandatory compatibility parameters and maintains identical mechanical and electrical interface characteristics with the original SB285-015H, with the exception of an increased current rating of 15A AC.

Parameter Comparison

Engineering Selection Recommendations

The SB285-015H is classified as an obsolete product. The SB25-015H/UC serves as a direct functional equivalent and substitute for applications requiring the SB285-015H.

Selection Basis:

The SB25-015H/UC maintains full mechanical and electrical interface compatibility with the SB285-015H across all critical parameters: identical DPDT circuit configuration, On-On switching function, 125V AC voltage rating, panel mount rear installation with 12.50mm circular cutout, round metal plunger actuator, and solder lug termination. Both components operate within the same temperature range (-10°C to 70°C) and share identical mechanical and electrical life specifications.

The SB25-015H/UC provides an increased current rating of 15A AC compared to the original 6A specification. This higher current capacity does not introduce compatibility issues and extends the operational envelope of the component for applications with higher current demands.

Both components maintain identical regulatory compliance status: REACH Unaffected, EAR99 export classification, and HTSUS code 8536.50.9035. The SB25-015H/UC carries RoHS3 compliance certification, providing additional environmental compliance assurance.

Frequently Asked Questions (FAQ)

Q: Can the SB25-015H/UC be used as a direct replacement for the SB285-015H?

A: Yes. The SB25-015H/UC is a direct substitute for the SB285-015H. Both components share identical circuit configuration (DPDT), switching function (On-On), voltage rating (125V AC), mounting type (panel mount, rear), panel cutout dimensions (12.50mm circular), actuator type (round metal plunger), and termination style (solder lug). The components are mechanically and electrically interchangeable.

Q: What is the difference between the SB285-015H and SB25-015H/UC?

A: The primary difference is the current rating. The SB285-015H is rated for 6A AC, while the SB25-015H/UC is rated for 15A AC. All other electrical and mechanical parameters are identical. The higher current rating of the SB25-015H/UC does not affect compatibility with existing circuit designs.

Q: Will the SB25-015H/UC fit in the same panel cutout as the SB285-015H?

A: Yes. Both components require an identical circular panel cutout of 12.50mm diameter and are designed for rear panel mount installation. No mechanical modification to the panel is required.

Q: Are there any compliance or certification differences between these parts?

A: Both components are REACH Unaffected and carry EAR99 export classification. The SB25-015H/UC includes RoHS3 compliance certification. Both share the same HTSUS code (8536.50.9035).

Q: Can I use the SB25-015H/UC in a circuit originally designed for 6A operation?

A: Yes. The SB25-015H/UC is fully compatible with circuits designed for the SB285-015H. The higher current rating does not create compatibility issues and does not affect circuit operation at lower current levels.

Q: What is the operating temperature range for both components?

A: Both the SB285-015H and SB25-015H/UC operate within the temperature range of -10°C to 70°C.
