LED Circuit Board Indicator CMI01Y Equivalent & Substitute Parts

Part Overview

The CMI01Y is a 5mm yellow LED circuit board indicator manufactured by Visual Communications Company (VCC). This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing design requirements and production continuity. The CMI01Y features a diffused, tinted lens with right-angle through-hole mounting, designed for standard 5mm T-1 3/4 LED applications in circuit board indicator applications.

Substitute Part Grouping Explanation

Substitute parts for the CMI01Y are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Color: Yellow (590nm peak wavelength)
• Configuration: Single LED
• Lens Type: Diffused, Tinted
• Lens Style: Round with Domed Top
• Lens Size: 5mm, T-1 3/4
• Mounting Type: Through Hole, Right Angle
• Compliance: ROHS3 Compliant, REACH Unaffected

Secondary Compatibility Parameters:

• Voltage Rating: 2.1V to 2.2V operating range
• Current Rating: 20mA to 30mA maximum ratings
• Millicandela Rating: 8mcd to 30mcd brightness range
• Viewing Angle: 60° to 120° acceptable range

The WP1503CB/YD from Kingbright meets all primary matching criteria and operates within acceptable secondary parameter ranges for direct substitution in circuit board indicator applications.

Engineering Selection Recommendations

The WP1503CB/YD from Kingbright is qualified as a direct substitute for the obsolete CMI01Y. Selection is based on the following engineering factors:

Compliance & Availability:

• WP1503CB/YD maintains ROHS3 compliance and REACH unaffected status, matching the original part's regulatory requirements
• Active product status ensures continued availability and supply chain reliability
• Bulk packaging option supports production requirements

Electrical & Optical Compatibility:

• Voltage rating differential (2.1V to 2.2V) is within acceptable tolerance for standard circuit board indicator applications
• Current rating increase (20mA to 30mA) provides design margin without requiring circuit modifications
• Millicandela rating increase (8mcd to 30mcd) enhances visibility while maintaining diffused lens characteristics
• Viewing angle reduction (120° to 60°) is acceptable for fixed-position circuit board indicator mounting

Mechanical & Thermal Compatibility:

• Identical lens size, style, and mounting configuration ensure direct PCB footprint compatibility
• Through-hole right-angle mounting maintains existing board layout requirements
• MSL rating 1 (Unlimited) eliminates moisture sensitivity concerns in standard storage and handling

Frequently Asked Questions (FAQ)

Q: Can the WP1503CB/YD replace the CMI01Y in existing circuit designs without modification?

A: Yes. The WP1503CB/YD is mechanically and electrically compatible with the CMI01Y. The 0.1V voltage increase and higher current/brightness ratings do not require circuit redesign for standard indicator applications. Existing current-limiting resistor values remain valid.

Q: What is the significance of the viewing angle difference between the two parts?

A: The CMI01Y provides 120° viewing angle while the WP1503CB/YD provides 60° viewing angle. For fixed-position circuit board indicators where the LED is viewed from a specific direction, the narrower 60° angle is acceptable and typical for this application class. If wide-angle visibility is critical, this parameter must be evaluated against specific application requirements.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. Regulatory and export compliance requirements are equivalent.

Q: How does the increased brightness (30mcd vs. 8mcd) affect circuit design?

A: The WP1503CB/YD's higher millicandela rating indicates greater light output at the same current. Existing current-limiting resistor values designed for the CMI01Y will operate the WP1503CB/YD at its rated 30mA maximum, producing proportionally brighter indication. If reduced brightness is required, resistor values may be adjusted upward to limit current below 30mA.

Q: What is the packaging difference, and does it affect component handling?

A: The CMI01Y is supplied in standard packaging while the WP1503CB/YD is supplied in bulk packaging. Both maintain MSL rating 1 (Unlimited), eliminating moisture sensitivity concerns. Bulk packaging does not affect component performance or storage requirements.

Q: Is the WP1503CB/YD suitable for high-volume production replacement?

A: Yes. The WP1503CB/YD is an active product with 7263 pieces in stock, ensuring supply continuity for production requirements. Active product status provides long-term availability compared to the obsolete CMI01Y.
