P01-24-B-1B Equivalent & Substitute Parts

Part Overview

The P01-24-B-1B is an incandescent panel indicator manufactured by NKK Switches, designed for 24V AC applications with a 25mA current rating. This component features a white lamp with a clear lens and a rectangular panel cutout measuring 0.66" x 0.74" (16.76mm x 18.80mm). The product is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P01-24-B-1B is determined by the following critical parameters:

• Lamp Color & Lens Transparency: White lamp with clear lens output
• Panel Cutout Compatibility: Rectangle shape with dimensions 0.66" x 0.74" (16.76mm x 18.80mm)
• Electrical Ratings: Operating voltage and current specifications
• Regulatory Compliance: RoHS3 and REACH status

The identified substitute part UB204KW036B-3JB shares the same manufacturer (NKK Switches), white lamp color, and equivalent regulatory compliance. However, this substitute represents a technology transition from incandescent to LED technology, which introduces differences in voltage rating (3.3V vs. 24V), current consumption (20mA vs. 25mA), and panel cutout geometry (square vs. rectangle).

Parameter Comparison

Engineering Selection Recommendations

The P01-24-B-1B is obsolete and no longer in active production. The UB204KW036B-3JB is the identified substitute from NKK Switches and maintains active product status with equivalent regulatory compliance (ROHS3 and REACH).

Selection of UB204KW036B-3JB requires evaluation of the following design considerations:

• Voltage Compatibility: The substitute operates at 3.3V versus the original 24V AC specification. System power supply architecture must accommodate this voltage difference.
• Panel Cutout Geometry: The substitute features a square cutout (0.69" x 0.69") compared to the rectangular cutout (0.66" x 0.74") of the original part. Panel modifications may be required.
• Lens Transparency: The substitute provides diffused lens transparency versus the clear lens of the original part, affecting light distribution characteristics.
• Technology Transition: Migration from incandescent to LED technology provides improved reliability and reduced power consumption.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications subject to these requirements.

Frequently Asked Questions (FAQ)

Q: Can the UB204KW036B-3JB directly replace the P01-24-B-1B without modifications?

A: Direct replacement is not possible without design modifications. The substitute differs in voltage rating (3.3V vs. 24V), panel cutout geometry (square vs. rectangle), and lens transparency (diffused vs. clear). Panel cutout enlargement and power supply reconfiguration are required.

Q: What are the key electrical differences between these parts?

A: The P01-24-B-1B operates at 24V AC with 25mA current consumption. The UB204KW036B-3JB operates at 3.3V with 20mA maximum current. The substitute requires a different power supply architecture and current-limiting circuit design.

Q: Are both parts RoHS3 compliant?

A: Yes, both the P01-24-B-1B and UB204KW036B-3JB are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for restricted substance use.

Q: What is the impact of lens transparency differences?

A: The original part features a clear lens providing direct light transmission. The substitute features a diffused lens that scatters light over a wider viewing angle. Application requirements for light distribution and intensity must be evaluated.

Q: Are there packaging differences between these parts?

A: The P01-24-B-1B is packaged in standard format with 855 pieces available in inventory. The UB204KW036B-3JB is supplied in bulk packaging with 1031 pieces available in inventory.
