CMDA2BR7D1S Red LED Diffused 1206 SMD Equivalent & Substitute Parts

Part Overview

The CMDA2BR7D1S is a red diffused LED in 1206 (3216 Metric) surface mount package manufactured by Visual Communications Company (VCC). This component functions as a red LED indication light with a forward voltage of 2.1V and 10mcd brightness rating. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing design support, maintenance, and production continuity. Equivalent parts must maintain identical electrical characteristics, mechanical dimensions, and optical properties to ensure direct replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CMDA2BR7D1S is determined by strict equivalence across four parameter categories:

Electrical Parameters: Forward voltage (Vf) of 2.1V and test current of 20mA must be maintained to ensure proper circuit operation without requiring resistor value recalculation or power supply adjustment.

Optical Parameters: Red color, diffused lens transparency, 10mcd brightness rating, 630nm peak wavelength, and 170° viewing angle must remain constant to preserve the intended indication function and user visibility characteristics.

Mechanical Parameters: 1206 (3216 Metric) package, surface mount configuration, rectangular flat-top lens style, 2.00mm x 1.60mm lens dimensions, and 3.20mm x 1.60mm x 1.10mm maximum body dimensions ensure PCB footprint compatibility and assembly process compatibility.

Compliance Parameters: RoHS3 compliance is required for regulatory alignment. MSL rating may vary within acceptable handling limits for manufacturing environments.

The HSMS-C150 from Broadcom Limited meets all four parameter categories and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The HSMS-C150 (Broadcom Limited) is the qualified substitute for the obsolete CMDA2BR7D1S. Selection is based on the following engineering criteria:

Electrical Compatibility: Both parts operate at identical forward voltage (2.1V) and test current (20mA), eliminating the need for circuit redesign or component value adjustment.

Optical Equivalence: Matching color, diffused lens transparency, 10mcd brightness, 630nm peak wavelength, and 170° viewing angle ensure the substitute performs the intended red LED indication function without modification to the user interface or visibility characteristics.

Mechanical Interchangeability: Identical 1206 (3216 Metric) package dimensions, surface mount configuration, and lens geometry provide direct PCB footprint compatibility. No layout modifications or assembly process changes are required.

Compliance Status: Both parts are ROHS3 compliant, maintaining regulatory alignment. The HSMS-C150 carries REACH Unaffected status, providing additional environmental compliance documentation.

Product Availability: The HSMS-C150 is in active production status with substantial inventory availability (62,200 pcs), ensuring long-term supply continuity compared to the obsolete CMDA2BR7D1S.

Moisture Handling: The HSMS-C150 has MSL 2A (4 weeks) versus the original MSL 1 (unlimited). This represents a minor handling constraint requiring storage in dry conditions for up to 4 weeks post-reflow, which is standard practice in modern manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can the HSMS-C150 be used as a direct replacement for CMDA2BR7D1S without circuit modification?

A: Yes. The HSMS-C150 matches all critical electrical parameters (2.1V forward voltage, 20mA test current) and optical specifications (10mcd, 630nm, diffused red). No resistor values, power supply adjustments, or circuit topology changes are required.

Q: Are the physical dimensions identical between these two parts?

A: Yes. Both parts use the 1206 (3216 Metric) package with identical body dimensions (3.20mm L x 1.60mm W x 1.10mm max height) and lens dimensions (2.00mm x 1.60mm). PCB footprints are directly compatible.

Q: What is the difference in Moisture Sensitivity Level (MSL) between the two parts?

A: The CMDA2BR7D1S has MSL 1 (unlimited moisture exposure tolerance), while the HSMS-C150 has MSL 2A (4-week tolerance after reflow). The HSMS-C150 requires storage in dry conditions for up to 4 weeks post-assembly, which aligns with standard manufacturing practices and does not impact field performance.

Q: Is the HSMS-C150 available in the same packaging format?

A: The HSMS-C150 is supplied in Cut Tape (CT) and Digi-Reel® packaging, which is standard for high-volume surface mount assembly. The original CMDA2BR7D1S packaging format is not specified in available documentation. Both formats are compatible with automated pick-and-place equipment.

Q: What is the wavelength difference between the two parts?

A: The CMDA2BR7D1S lists peak wavelength as 630nm without a dominant wavelength specification. The HSMS-C150 specifies dominant wavelength as 626nm and peak wavelength as 630nm. Both values fall within the standard red LED spectrum and produce visually identical red indication.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant. The HSMS-C150 additionally carries REACH Unaffected status. Both share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Q: Can the HSMS-C150 be used in existing inventory management systems coded for CMDA2BR7D1S?

A: The HSMS-C150 is a functional and electrical equivalent suitable for direct substitution. However, inventory management, bill of materials, and procurement systems should be updated to reflect the new part number (HSMS-C150) and manufacturer (Broadcom Limited) for accurate tracking and future supply chain management.
