LED Circuit Board Indicator Bar CMS01G Equivalent & Substitute Parts

Part Overview

The CMS01G is a green LED circuit board indicator bar manufactured by Visual Communications Company (VCC). This component is classified as an obsolete product, featuring a single SIP configuration with diffused, tinted lens in a rectangle with flat top design. The part operates at 2.2V with 20mA current rating and delivers 8 millicandela brightness at a 565nm peak wavelength.

Due to the obsolete status of the CMS01G, identifying equivalent substitute parts is essential for ongoing production support, maintenance applications, and design continuity. Substitute components must maintain electrical and mechanical compatibility within the specified parameter tolerances.

The substitute part is currently in active production status with confirmed inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The SSF-LXH25780GD is a direct substitute for the obsolete CMS01G based on electrical and mechanical parameter equivalence. Both components are ROHS3 compliant and carry identical MSL ratings, ensuring regulatory and environmental compatibility.

The substitute part offers the following advantages:

Product Status: The SSF-LXH25780GD maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete CMS01G.

Inventory Availability: The substitute part has confirmed inventory of 9501 pieces in stock, providing immediate procurement capability.

Brightness Enhancement: The SSF-LXH25780GD delivers 9 millicandela compared to the CMS01G's 8 millicandela, representing a 12.5% brightness increase while maintaining all other electrical specifications.

Mechanical Considerations: The SSF-LXH25780GD features a right-angle mounting configuration with specified lens dimensions of 7.00mm x 2.50mm. PCB layout and mounting hole positioning must be verified for mechanical fit in existing designs.

Compliance Certification: Both components maintain ROHS3 compliance and REACH unaffected status, with identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Frequently Asked Questions (FAQ)

Q: Can the SSF-LXH25780GD directly replace the CMS01G without circuit modifications?

A: The SSF-LXH25780GD maintains identical electrical specifications (2.2V, 20mA, 565nm, 110° viewing angle). However, the right-angle mounting configuration and specified lens dimensions (7.00mm x 2.50mm) require verification of PCB layout compatibility. Mounting hole positions and clearances must be confirmed before implementation.

Q: What is the brightness difference between these components?

A: The CMS01G operates at 8 millicandela while the SSF-LXH25780GD operates at 9 millicandela. This 12.5% increase in brightness occurs within the same electrical operating parameters and does not affect circuit design or current limiting requirements.

Q: Are both components RoHS compliant?

A: Both the CMS01G and SSF-LXH25780GD are ROHS3 compliant with MSL rating 1 (unlimited moisture sensitivity level). Both components are REACH unaffected and carry identical ECCN and HTSUS classifications.

Q: Why is the CMS01G listed as obsolete?

A: The CMS01G is classified as obsolete by the original manufacturer (VCC). The SSF-LXH25780GD from Lumex Opto/Components Inc. is an active production equivalent that provides functional and electrical continuity for applications requiring green LED circuit board indicator bars.

Q: What are the lens dimensions of the substitute part?

A: The SSF-LXH25780GD features a rectangle with flat top lens measuring 7.00mm x 2.50mm. The CMS01G lens dimensions are not specified in the available documentation. Physical verification is required to confirm fit within existing mechanical constraints.

Q: Are there any supply chain advantages to using the substitute part?

A: The SSF-LXH25780GD is in active production with 9501 pieces currently in stock, compared to the obsolete CMS01G with limited remaining inventory of 628 pieces. The substitute part provides superior long-term availability and supply continuity.
