CMD333HRC-6 Equivalent & Substitute Parts Reference

Part Overview

The CMD333HRC-6 is a red LED indication component manufactured by Visual Communications Company (VCC) in a T-1 3/4 through-hole radial package. This discrete 1.7V LED features a 5mm round domed lens with clear transparency and 600mcd brightness rating, designed for standard indicator applications. The product is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement. Equivalent parts must maintain mechanical compatibility with the T-1 3/4 form factor and electrical performance within acceptable operating parameters for red LED indication circuits.

Substitute Part Grouping Explanation

Substitute parts for the CMD333HRC-6 are identified based on strict parameter matching within the following criteria:

Mechanical Compatibility Requirements:

• Lens size must be 5mm T-1 3/4 form factor
• Mounting type must be through-hole
• Package configuration must be radial
• Height must not exceed design envelope constraints

Electrical Compatibility Requirements:

• Color must be red
• Lens transparency must be clear
• Forward voltage (Vf) must be within acceptable circuit design range (1.7V to 1.9V typical)
• Millicandela rating must support indication visibility (600mcd minimum)
• Viewing angle must be compatible with application requirements (24° to 25°)

Regulatory & Compliance Requirements:

• RoHS3 compliance mandatory
• REACH unaffected status required
• ECCN and HTSUS classifications must align

The HLMP-C625-P0000 meets all mechanical, electrical, and regulatory criteria for substitution with the CMD333HRC-6.

Parameter Comparison

Engineering Selection Recommendations

The HLMP-C625-P0000 manufactured by Broadcom Limited is a valid substitute for the obsolete CMD333HRC-6. Selection is supported by the following engineering factors:

Mechanical Compatibility: The substitute maintains identical T-1 3/4 lens size, through-hole mounting configuration, and radial package geometry. The height difference of 0.53mm (9.14mm versus 8.61mm) must be evaluated against specific PCB layout and enclosure clearance requirements in the target application.

Electrical Compatibility: Forward voltage increases from 1.7V to 1.9V (0.2V difference). This parameter change requires circuit design review to confirm current-limiting resistor values remain appropriate. The test current specification decreases from 30mA to 20mA; however, both parts operate within standard red LED operating ranges. Brightness increases from 600mcd to 700mcd, providing enhanced indication visibility without functional degradation.

Regulatory Compliance: Both parts maintain ROHS3 compliance, REACH unaffected status, and identical ECCN/HTSUS classifications, ensuring regulatory equivalence for procurement and deployment.

Product Status Advantage: The substitute is classified as active production status, ensuring long-term availability and supply chain stability compared to the obsolete main part.

Moisture Protection: The substitute provides superior moisture sensitivity rating (MSL 1 Unlimited versus MSL 2 1 Year), offering improved reliability in storage and operational environments.

Frequently Asked Questions (FAQ)

Q: Can the HLMP-C625-P0000 be used as a direct replacement for CMD333HRC-6 without circuit modifications?

A: The substitute is mechanically and functionally compatible. However, the forward voltage increase from 1.7V to 1.9V requires circuit design review. If the original circuit uses a fixed current-limiting resistor, recalculation may be necessary to maintain proper LED operating current. Consult the specific circuit schematic and resistor values.

Q: What is the significance of the 0.53mm height difference?

A: The HLMP-C625-P0000 is 0.53mm taller (9.14mm maximum height versus 8.61mm). This difference must be evaluated against PCB layout constraints, enclosure clearances, and any mechanical fixtures or covers in the target application. Measure available vertical space before substitution.

Q: Does the higher millicandela rating (700mcd vs 600mcd) affect circuit operation?

A: The increased brightness does not negatively affect circuit operation. The higher millicandela rating provides enhanced indication visibility. If the original application requires specific brightness levels, the increased output may exceed requirements but will not cause functional failure.

Q: Are the wavelength differences (660nm vs 650nm peak) significant?

A: Both wavelengths fall within the red spectrum and are visually indistinguishable to the human eye. The 10nm difference does not affect functional performance in standard indication applications. Specialized applications requiring specific wavelength characteristics should reference detailed spectral data.

Q: What does the improved MSL rating mean for the substitute part?

A: The HLMP-C625-P0000 has MSL 1 (Unlimited) versus the original MSL 2 (1 Year). This indicates superior moisture protection and longer shelf life without special storage requirements. The substitute offers improved reliability in standard warehouse and operational environments.

Q: Are both parts RoHS3 compliant?

A: Yes. Both CMD333HRC-6 and HLMP-C625-P0000 are ROHS3 compliant and REACH unaffected, ensuring regulatory equivalence for procurement in regions with RoHS requirements.

Q: What viewing angle difference exists between the parts?

A: The viewing angle increases from 24° to 25° (1° difference). This minimal change does not affect functional performance in standard indication applications. Both angles provide comparable light distribution characteristics for typical LED indicator circuits.

Q: Is the substitute available in the same packaging format?

A: The HLMP-C625-P0000 is supplied in bulk packaging, while the original CMD333HRC-6 packaging format is not specified in available data. Confirm packaging requirements with your procurement department, as bulk packaging may require different handling and storage procedures.
