Key Parameters

Substitute Part Grouping Explanation

Substitution of the CMDA2AY7D1S is determined by strict alignment of the following electrical and mechanical parameters:

Electrical Parameters:

• Forward voltage (Vf): 2.2V typical
• Test current: 20mA
• Brightness: 15 millicandela
• Peak wavelength: 570nm (green spectrum)
• Viewing angle: 170°

Mechanical Parameters:

• Package type: 1206 (3216 Metric) surface mount
• Physical dimensions: 3.20mm L x 1.60mm W
• Maximum height: 1.10mm
• Lens configuration: Rectangle with flat top, diffused white lens

Compliance Parameters:

• RoHS3 compliance required
• ECCN: EAR99
• HTSUS: 8541.41.0000

A substitute part must match all electrical parameters, maintain identical package dimensions and mounting type, and satisfy the same regulatory compliance requirements. The HSMG-C150 from Broadcom Limited meets these criteria.

Engineering Selection Recommendations

The HSMG-C150 from Broadcom Limited is a direct functional equivalent for the obsolete CMDA2AY7D1S. Selection of this substitute is based on the following engineering criteria:

Electrical Equivalence: All critical electrical parameters match exactly, including forward voltage (2.2V), test current (20mA), brightness (15mcd), and peak wavelength (570nm). The dominant wavelength specification of 572nm in the HSMG-C150 falls within the green spectrum and is compatible with the 570nm peak wavelength of the original part.

Mechanical Compatibility: Both parts utilize identical 1206 (3216 Metric) surface mount packaging with matching physical dimensions (3.20mm L x 1.60mm W) and maximum height (1.10mm). This ensures direct PCB footprint compatibility without layout modifications.

Regulatory Compliance: Both parts are ROHS3 compliant and share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, satisfying regulatory requirements for equivalent component substitution.

Product Availability: The HSMG-C150 maintains active product status with substantial inventory availability (59,170 pieces), ensuring reliable sourcing for production and design support compared to the obsolete CMDA2AY7D1S.

Frequently Asked Questions (FAQ)

Q: Can the HSMG-C150 be used as a direct replacement for the CMDA2AY7D1S without circuit modifications?

A: Yes. The HSMG-C150 is electrically and mechanically equivalent. Both parts operate at 2.2V forward voltage with 20mA test current and produce identical brightness (15mcd) and viewing angle (170°). PCB footprints are identical, requiring no layout changes.

Q: What is the difference between the peak wavelength (570nm) and dominant wavelength (572nm) specifications?

A: Peak wavelength represents the wavelength at maximum spectral intensity. Dominant wavelength represents the single wavelength that best describes the perceived color to the human eye. Both values fall within the green spectrum and are functionally equivalent for LED indication applications. The 2nm difference is within normal manufacturing tolerance for green LEDs.

Q: Are there any moisture sensitivity differences between these parts?

A: The CMDA2AY7D1S has MSL 1 (Unlimited), while the HSMG-C150 has MSL 2A (4 Weeks). MSL 2A requires storage in dry conditions and has a 4-week floor life after moisture exposure. For applications with standard handling and storage practices, this difference does not impact functionality.

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

A: Yes. The HSMG-C150 is supplied in Cut Tape (CT) and Digi-Reel® packaging, which are standard surface mount component formats compatible with automated assembly equipment. The component package itself (1206 / 3216 Metric) is identical.

Q: What is the REACH compliance status of the HSMG-C150?

A: The HSMG-C150 is listed as REACH Unaffected, indicating compliance with REACH regulations without substance of concern restrictions.
