CMW01G LED Circuit Board Indicator Equivalent & Substitute Parts

Part Overview

The CMW01G is a 3mm green diffused LED circuit board indicator manufactured by Visual Communications Company (VCC). This component is classified as obsolete, necessitating identification of active equivalent and substitute parts for ongoing design support and procurement. The CMW01G functions as a single green indicator LED with through-hole right-angle mounting, suitable for circuit board applications requiring visual status indication.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMW01G is determined by strict alignment of the following critical parameters:

Primary Matching Criteria:

• Color: Green
• Wavelength - Peak: 565nm
• Configuration: Single
• Current Rating: 20mA
• Lens Type: Diffused, Tinted
• Lens Style: Round with Domed Top
• Lens Size: 3mm, T-1
• Mounting Type: Through Hole, Right Angle
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Secondary Tolerance Parameters:

• Voltage Rating: 2.1V to 2.2V (acceptable variance)
• Millicandela Rating: 12.5mcd to 22.5mcd (brightness variance acceptable within application context)
• Viewing Angle: 40° to 120° (application-dependent selection)

All substitute parts listed meet the primary matching criteria. Variations in voltage rating, brightness, and viewing angle reflect manufacturing differences across suppliers while maintaining functional equivalence for standard circuit board indicator applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Dialight Series 551):

The Dialight parts 5510001875F, 5510201010F, and 5510201F are active production components that satisfy all primary matching criteria. These parts maintain identical electrical specifications (20mA, 565nm wavelength, diffused green lens, 3mm T-1 form factor) with voltage ratings of 2.1V, representing a 0.1V reduction from the CMW01G. All three Dialight substitutes carry ROHS3 compliance and MSL 1 rating, matching the original part's environmental certifications.

High-Availability Alternative (Lumex SSF-LXH103LGD):

The SSF-LXH103LGD from Lumex Opto/Components Inc. meets all primary matching criteria with 27,663 units in stock, providing superior procurement availability. This part delivers 15mcd brightness (2.4mcd above the CMW01G) and an 80° viewing angle, suitable for applications where increased brightness or wider viewing angle is acceptable. Voltage rating is 2.1V with full ROHS3 and MSL 1 compliance.

Similar Specification Alternative (Kingbright WP934CB/GD):

The WP934CB/GD from Kingbright satisfies all primary matching criteria with 25,477 units in stock. This part maintains the original 2.2V voltage rating and delivers 22.5mcd brightness with a 40° viewing angle. The narrower viewing angle and increased brightness represent a different optical profile suitable for applications requiring concentrated light output. Full ROHS3 and MSL 1 compliance is maintained.

Selection Basis:

All substitute parts are active production components with ROHS3 compliance and unlimited moisture sensitivity rating. Selection between substitutes depends on application requirements for viewing angle and brightness characteristics. Voltage tolerance of 2.1V to 2.2V is acceptable for standard circuit board indicator applications.

Frequently Asked Questions (FAQ)

Q: Can the CMW01G be directly replaced with any of the listed substitutes?

A: Yes. All listed substitute parts meet the primary matching criteria: green color, 565nm wavelength, single configuration, 20mA current rating, diffused tinted lens, 3mm T-1 form factor, through-hole right-angle mounting, ROHS3 compliance, and MSL 1 rating. Voltage variations between 2.1V and 2.2V are acceptable for standard circuit board indicator applications.

Q: What is the difference between the Dialight substitutes?

A: The three Dialight parts (5510001875F, 5510201010F, 5510201F) share identical electrical specifications. The primary difference is viewing angle specification: 5510001875F does not specify viewing angle, while 5510201010F and 5510201F both specify 60°. All three deliver 12.6mcd brightness. Selection between these parts depends on application viewing angle requirements.

Q: How does the Lumex SSF-LXH103LGD differ from the original CMW01G?

A: The SSF-LXH103LGD maintains all primary matching criteria but offers increased brightness (15mcd versus 12.5mcd) and an 80° viewing angle compared to the CMW01G's 120° angle. Voltage rating is 2.1V. These differences are acceptable for standard indicator applications where increased brightness or slightly narrower viewing angle does not impact functionality.

Q: What are the advantages of the Kingbright WP934CB/GD?

A: The WP934CB/GD maintains the original 2.2V voltage rating and provides the highest brightness among substitutes at 22.5mcd. The 40° viewing angle is narrower than the CMW01G, concentrating light output for applications requiring focused illumination. This part offers the largest inventory availability at 25,477 units in stock.

Q: Are all substitutes RoHS compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification, matching the original CMW01G specification. All parts also maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which substitute offers the best procurement availability?

A: The Lumex SSF-LXH103LGD offers the highest inventory availability with 27,663 units in stock, followed by the Kingbright WP934CB/GD with 25,477 units. Dialight parts range from 840 to 962 units in stock.

Q: Can I use a substitute with different viewing angle in my application?

A: Viewing angle selection depends on application requirements. The CMW01G provides 120° viewing angle. Substitutes offer 40° to 80° angles. Narrower viewing angles concentrate light output; wider angles distribute light across a broader area. Select based on your specific application's visibility requirements.

Q: What is the voltage tolerance for these substitutes?

A: The CMW01G operates at 2.2V, while most substitutes operate at 2.1V. This 0.1V difference is acceptable for standard circuit board indicator applications. The Kingbright WP934CB/GD maintains the original 2.2V rating if exact voltage matching is required.
