LED Circuit Board Indicator Bar CMS01R Equivalent & Substitute Parts

Part Overview

The CMS01R is a red 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 2V with 20mA current rating and delivers 12.5mcd brightness at a 625nm peak wavelength.

Due to its obsolete status, identifying equivalent substitute parts is necessary for ongoing design support, maintenance, and production continuity. Active alternative components with compatible electrical and mechanical specifications are available to replace this part in existing applications.

The substitute part SSF-LXH25780ID meets all electrical and mechanical compatibility criteria while maintaining full regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The SSF-LXH25780ID from Lumex Opto/Components Inc. is a direct functional equivalent for the obsolete CMS01R. Selection of this substitute part is supported by the following engineering factors:

Product Status Consideration: The CMS01R is classified as obsolete, making the active SSF-LXH25780ID the appropriate replacement for new designs and ongoing production support.

Electrical Equivalence: Both parts operate at identical voltage (2V) and current (20mA) ratings. The SSF-LXH25780ID delivers 15mcd brightness compared to the CMS01R's 12.5mcd, providing equal or superior optical performance within the same electrical envelope.

Mechanical Compatibility: Both components feature identical configuration (Bar - Single, SIP), lens type (Diffused, Tinted), and lens style (Rectangle with Flat Top). The SSF-LXH25780ID includes specified lens dimensions (7.00mm x 2.50mm) and offers a right-angle mounting variant, providing layout flexibility for existing PCB designs.

Regulatory Compliance: Both parts maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and REACH unaffected status, ensuring regulatory continuity in applications requiring these certifications.

Wavelength Specification: The SSF-LXH25780ID operates at 635nm peak wavelength compared to the CMS01R's 625nm. Both wavelengths fall within the red LED spectrum and maintain the same 110° viewing angle, ensuring consistent visual performance in indicator applications.

Frequently Asked Questions (FAQ)

Q: Can the SSF-LXH25780ID directly replace the CMS01R without circuit modifications?

A: The SSF-LXH25780ID is electrically and mechanically compatible with the CMS01R. Both parts operate at 2V, 20mA with identical configuration and lens specifications. No circuit modifications are required for direct substitution in through-hole mounting applications.

Q: What is the difference between the 625nm and 635nm wavelengths?

A: Both wavelengths are within the red LED spectrum. The 625nm (CMS01R) represents a slightly deeper red, while the 635nm (SSF-LXH25780ID) represents a standard red. The difference is not perceptible in typical indicator applications and both maintain the same 110° viewing angle.

Q: Does the SSF-LXH25780ID's higher brightness (15mcd vs. 12.5mcd) affect circuit design?

A: No. Both parts operate at identical voltage and current ratings (2V, 20mA). The higher brightness of the SSF-LXH25780ID is achieved through improved optical design, not increased electrical consumption. Existing circuit designs require no modification.

Q: What does "Right Angle" mounting mean for the SSF-LXH25780ID?

A: The SSF-LXH25780ID is available in a right-angle variant, meaning the LED leads are bent 90 degrees relative to the lens. This allows the LED to be mounted parallel to the PCB surface rather than perpendicular. Standard through-hole mounting is also available.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the CMS01R and SSF-LXH25780ID are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level and REACH unaffected status, meeting current regulatory requirements for electronic components.

Q: Why is the CMS01R obsolete?

A: The CMS01R is classified as obsolete by the manufacturer. The SSF-LXH25780ID from Lumex represents the active equivalent for new designs and production continuity.

Q: Can the SSF-LXH25780ID be used in existing PCB designs without layout changes?

A: Yes, for standard through-hole mounting. The SSF-LXH25780ID maintains identical electrical specifications and lens dimensions. If the right-angle variant is selected, PCB layout modifications may be necessary depending on the original mounting orientation.
