LED Circuit Board Indicator CMW01R Equivalent & Substitute Parts

Part Overview

The CMW01R is a 3mm red diffused LED circuit board indicator manufactured by Visual Communications Company (VCC). This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design support and procurement. The CMW01R features a through-hole right-angle mounting configuration with a 2V operating voltage and 20mA rated current, designed for standard circuit board indicator applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete CMW01R is based on matching the following critical parameters:

Mechanical Compatibility:

• Lens size: 3mm, T-1 form factor
• Mounting type: Through hole, right angle configuration
• Lens style: Round with domed top

Electrical Compatibility:

• Voltage rating: 2V
• Current rating: 20mA
• Configuration: Single LED

Regulatory Compliance:

• RoHS3 compliance
• REACH unaffected status

The substitute part WP934CB/ID from Kingbright satisfies all mechanical and electrical compatibility requirements while maintaining active product status and equivalent regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The WP934CB/ID from Kingbright is the designated substitute for the obsolete CMW01R. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and procurement cycles. The WP934CB/ID is currently in active production status, providing supply chain continuity and long-term availability.

Electrical and mechanical parameters are equivalent across voltage rating, current rating, lens size, and mounting configuration. The substitute part maintains the same through-hole right-angle form factor and 3mm T-1 lens geometry, enabling direct board-level replacement without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the WP934CB/ID directly replace the CMW01R in existing circuit board designs?

A: Yes. Both components share identical mechanical mounting specifications (through-hole right angle, 3mm T-1 lens), electrical ratings (2V, 20mA), and lens configuration (diffused, tinted, round domed top). No board redesign is required.

Q: What are the differences between these two parts?

A: The WP934CB/ID exhibits a peak wavelength of 627nm compared to the CMW01R at 625nm, a difference of 2nm within typical red LED spectral variation. The WP934CB/ID provides 22.5mcd brightness versus 20mcd for the CMW01R. The CMW01R features a 130° viewing angle while the WP934CB/ID has a 40° viewing angle. These differences reflect normal manufacturing variation within the red LED indicator category.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the CMW01R and WP934CB/ID are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Q: What is the packaging difference?

A: The CMW01R is supplied in standard packaging, while the WP934CB/ID is supplied in bulk packaging. Both are suitable for through-hole assembly processes.

Q: Why is the CMW01R listed as obsolete?

A: The CMW01R has been discontinued by Visual Communications Company. The WP934CB/ID from Kingbright provides equivalent functionality and is actively manufactured, making it the appropriate selection for new designs and ongoing production requirements.
