CMDA6BA7D1S Orange LED 0603 SMD Equivalent & Substitute Parts

Part Overview

The CMDA6BA7D1S is an orange diffused LED in 0603 (1608 Metric) surface mount package manufactured by Visual Communications Company (VCC). This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The part operates at 1.9V forward voltage with 90mcd brightness rating and 170° viewing angle, designed for standard LED indication applications in compact form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMDA6BA7D1S is determined by the following critical parameters:

Primary Compatibility Criteria:

• Package / Case: 0603 (1608 Metric) surface mount
• Color: Orange
• Lens Transparency: Diffused
• Mounting Type: Surface Mount
• Voltage - Forward (Vf): 1.9V nominal operation
• Current - Test: 20mA standard test condition
• Viewing Angle: 170° minimum
• Millicandela Rating: 90mcd minimum
• RoHS Status: ROHS3 Compliant

Identified Substitutes:

Direct Equivalent (HSML-C190): Broadcom Limited HSML-C190 meets all primary compatibility criteria with identical electrical specifications (1.9V, 20mA, 90mcd, 170° viewing angle) and mechanical form factor. This part is active status with full RoHS3 compliance.

Similar Substitutes (5975203402F, 5975203407F): Dialight parts 5975203402F and 5975203407F share the 0603 package, orange color, and diffused lens but operate at 2.2V forward voltage with reduced brightness (2mcd) and narrower viewing angle (152°). These parts are functionally similar but with measurable parameter deviations.

Parameter Comparison

Engineering Selection Recommendations

HSML-C190 (Broadcom Limited): This part is the primary substitute for CMDA6BA7D1S. It maintains identical electrical performance (1.9V forward voltage, 90mcd brightness, 170° viewing angle) and mechanical compatibility (0603 package, 1.60mm x 0.80mm x 0.80mm). Both parts are ROHS3 compliant. The HSML-C190 is active status with established supply chain availability (85,300 pcs in stock). The MSL rating difference (1 vs 2A) reflects standard industry variation for active components. This substitution requires no circuit redesign.

5975203402F and 5975203407F (Dialight): These parts are functionally similar but operate at elevated forward voltage (2.2V vs 1.9V) and reduced brightness (2mcd vs 90mcd). The viewing angle is narrower (152° vs 170°). These specifications represent material deviations from the original part. Selection of these parts requires circuit validation to confirm voltage tolerance and brightness adequacy for the application. Both parts are active status and ROHS3 compliant. The 5975203407F offers Tape & Reel packaging for automated assembly.

Compliance Status: All substitute parts maintain ROHS3 compliance and EAR99 export classification consistent with the original CMDA6BA7D1S.

Frequently Asked Questions (FAQ)

Q: Can HSML-C190 be used as a direct replacement for CMDA6BA7D1S without circuit modification?

A: Yes. The HSML-C190 maintains identical forward voltage (1.9V), test current (20mA), brightness (90mcd), and viewing angle (170°). The 0603 package and surface mount configuration are identical. No circuit redesign is required.

Q: What are the key differences between HSML-C190 and the Dialight parts (5975203402F, 5975203407F)?

A: The HSML-C190 matches the original CMDA6BA7D1S electrical specifications exactly. The Dialight parts operate at 2.2V forward voltage (0.3V higher) and provide significantly lower brightness (2mcd vs 90mcd). Viewing angle is also reduced from 170° to 152°. These differences require application-level validation.

Q: Are there packaging differences between the substitute parts?

A: Yes. HSML-C190 is supplied in Tape & Reel (TR) format. Dialight 5975203402F is supplied in Strip format, while 5975203407F is supplied in Tape & Reel (TR). The component form factor (0603) is identical across all parts.

Q: What is the significance of the MSL (Moisture Sensitivity Level) differences?

A: The original CMDA6BA7D1S has MSL 1 (unlimited shelf life). HSML-C190 has MSL 2A (4-week shelf life), and Dialight parts have MSL 3 (168-hour shelf life). Lower MSL ratings require stricter moisture control during storage and handling. This is standard industry variation for active components and does not affect electrical performance.

Q: Can the Dialight parts be used in applications requiring 90mcd brightness?

A: No. The Dialight parts (5975203402F, 5975203407F) provide only 2mcd brightness compared to the 90mcd requirement of CMDA6BA7D1S. This 45-fold reduction in brightness makes these parts unsuitable for applications with brightness specifications.

Q: What is the wavelength difference between HSML-C190 and the Dialight substitutes?

A: HSML-C190 has peak wavelength 609nm (dominant 605nm). Dialight parts have peak wavelength 605nm (dominant 606nm). These differences are within the orange LED spectrum and represent minor variations in color perception.

Q: Is the height difference (0.80mm vs 0.70mm) significant for PCB layout?

A: The HSML-C190 maintains the original 0.80mm height. Dialight parts are 0.70mm height. This 0.10mm difference is negligible for most PCB designs but should be verified if height clearance is constrained.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. CMDA6BA7D1S, HSML-C190, 5975203402F, and 5975203407F are all ROHS3 compliant. All parts share EAR99 export classification and 8541.41.0000 HTSUS code.
