MLW3015-12-RB-1A Equivalent & Substitute Parts

Part Overview

The MLW3015-12-RB-1A is a rocker switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 5A AC and 3A DC current ratings at 125V AC / 30V DC. The switch includes illumination via incandescent white light at 12 VAC nominal voltage and is designed for panel mount, snap-in installation with solder lug termination.

This part carries an Obsolete product status. Locating equivalent or substitute components becomes necessary when original inventory is depleted or when design flexibility permits alternative configurations that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the MLW3015-12-RB-1A is determined by strict alignment across the following electrical and mechanical parameters:

  • Circuit configuration (SPDT)
  • Current ratings (5A AC / 3A DC minimum)
  • Voltage ratings (125V AC / 30V DC minimum)
  • Mounting type (Panel Mount, Snap-In)
  • Termination style (Solder Lug)
  • Switch function (On-Mom)
  • Mechanical and electrical life specifications
  • Operating temperature range
  • Compliance certifications (UL, RoHS3)

The MLW3015-F-LF-2A qualifies as a substitute part within the MLW series. Both parts share identical electrical ratings, circuit topology, mounting configuration, and lifecycle specifications. Differences in illumination type (incandescent white versus LED green) and illumination voltage (12 VAC versus 2.1 VDC) represent design variations that do not affect core switching functionality but require circuit-level evaluation for illumination compatibility.

Engineering Selection Recommendations

Both the MLW3015-12-RB-1A and MLW3015-F-LF-2A maintain identical electrical performance specifications and UL approval status. Selection between these parts depends on illumination circuit requirements:

The MLW3015-12-RB-1A operates with 12 VAC incandescent illumination and is suitable for applications with AC power availability for indicator lighting.

The MLW3015-F-LF-2A operates with 2.1 VDC LED illumination and is suitable for applications with DC power availability or where lower illumination voltage is required. LED illumination provides extended operational life compared to incandescent technology.

Both parts carry ROHS3 compliance and UL certification, confirming regulatory alignment for industrial and commercial applications. The choice between white and green actuator colors and corresponding illumination colors should be determined by application-specific visual indication requirements and operator interface standards.

Frequently Asked Questions (FAQ)

Q: Can MLW3015-F-LF-2A directly replace MLW3015-12-RB-1A in existing designs?

A: Direct replacement is possible only if the illumination circuit can accommodate the change from 12 VAC incandescent to 2.1 VDC LED. The core switching function, electrical ratings, and mechanical interface are identical. Illumination power supply modification may be required.

Q: Are the panel cutout dimensions identical between these parts?

A: No. MLW3015-12-RB-1A specifies rectangular panel cutout dimensions of 18.70mm x 16.70mm, while MLW3015-F-LF-2A specifies square dimensions of 19.20mm². Panel mounting holes must be verified for mechanical compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are UL approved and ROHS3 compliant, with identical REACH and ECCN classifications (REACH Unaffected, EAR99).

Q: What is the difference in actuator appearance?

A: MLW3015-12-RB-1A features a white illuminated actuator with incandescent white illumination. MLW3015-F-LF-2A features a green illuminated actuator with LED green illumination. Both use concave (curved) actuator geometry.

Q: Are the electrical life and mechanical life ratings the same?

A: Yes. Both parts specify 30,000 mechanical cycles and 10,000 electrical cycles, with identical operating temperature ranges of -10°C to 50°C.
