Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BG1111C-TR is determined by the following critical parameters:

Primary Compatibility Criteria:

• Package / Case: 0603 (1608 Metric) surface mount format
• Color: Green
• Lens Transparency: Diffused
• Mounting Type: Surface Mount
• Voltage - Forward (Vf) (Typ): Range 1.9V to 2.2V (within typical circuit tolerance)
• Current - Test: 20mA
• Wavelength - Dominant: 555nm to 572nm (green spectrum range)

Secondary Considerations:

• Millicandela Rating: 2.4mcd to 20mcd (brightness variation acceptable for indication applications)
• Size / Dimension: 1.60mm L x 0.80mm W (standard 0603 footprint)
• Height (Max): 0.40mm to 0.90mm (within PCB assembly clearance limits)
• RoHS Status: ROHS3 Compliant
• Product Status: Active preferred for new designs; Not For New Designs acceptable for legacy support

The following substitute parts meet these criteria and are grouped by manufacturer and product status.

Parameter Comparison

Engineering Selection Recommendations

For New Designs (Active Product Status Required):

The VFHL1111C-4B23C-TR from Stanley Electric Co is the manufacturer-recommended substitute. This part maintains Stanley Electric Co lineage, operates at 1.9V forward voltage (0.2V lower than the original), and provides 20mcd brightness—approximately 8.3 times the original specification. The part is Active status and ROHS3 Compliant. Tape & Reel packaging is standard for production volumes.

The HSMG-C190, HSMG-C191, and HSMG-C197 from Broadcom Limited are functionally equivalent alternatives. All three operate at 2.2V forward voltage and provide 15mcd brightness. These parts are Active status and ROHS3 Compliant. Selection among these three variants depends on height constraints: HSMG-C197 (0.40mm max height) for space-constrained applications, HSMG-C191 (0.60mm max height) for standard applications, and HSMG-C190 (0.80mm max height) for applications with greater clearance.

The CMDA19AY7D1S from Visual Communications Company - VCC operates at 2.2V forward voltage with 15mcd brightness and 170° viewing angle. This part is Active status and ROHS3 Compliant with MSL 2 (1 Year) rating.

For Legacy Production Support (Obsolete Replacement):

The SML-310MTT86 from Rohm Semiconductor provides electrical compatibility at 2.2V forward voltage with 16mcd brightness. This part is classified as Not For New Designs but remains available for legacy production. Note that this part features Clear lens transparency rather than Diffused, which may affect optical appearance in the application.

The CMDA19AG7D1S from Visual Communications Company - VCC operates at 3.4V forward voltage with significantly higher brightness (145mcd). This part is suitable only for applications where higher forward voltage and brightness are acceptable.

Compliance Verification:

All recommended substitute parts are ROHS3 Compliant and REACH Unaffected, matching the original BG1111C-TR compliance status. Moisture Sensitivity Level (MSL) ratings vary; verify MSL requirements against your assembly process conditions.

Frequently Asked Questions (FAQ)

Q: Can the VFHL1111C-4B23C-TR directly replace the BG1111C-TR without circuit modification?

A: The VFHL1111C-4B23C-TR operates at 1.9V forward voltage compared to the original 2.1V. This 0.2V difference is within typical circuit tolerance for LED indicator applications. However, verify that your current-limiting resistor value accommodates the lower forward voltage. The higher brightness (20mcd vs. 2.4mcd) is suitable for indication applications and does not require circuit changes.

Q: What is the difference between HSMG-C190, HSMG-C191, and HSMG-C197?

A: These three Broadcom Limited parts are electrically identical (2.2V, 15mcd, 572nm dominant wavelength) but differ in maximum height: HSMG-C190 (0.80mm), HSMG-C191 (0.60mm), and HSMG-C197 (0.40mm). Select based on your PCB assembly clearance requirements. All three are Active status and suitable for new designs.

Q: Why does the CMDA19AG7D1S have a 3.4V forward voltage?

A: The CMDA19AG7D1S operates at 3.4V forward voltage, which is significantly higher than the original 2.1V specification. This part is not recommended as a direct substitute unless your circuit design accommodates higher forward voltage. The 145mcd brightness is also substantially higher than the original 2.4mcd specification.

Q: Is the SML-310MTT86 suitable for new designs?

A: No. The SML-310MTT86 is classified as Not For New Designs. This part is available only for legacy production support of existing designs. For new designs, select from the Active status alternatives: VFHL1111C-4B23C-TR, HSMG-C190, HSMG-C191, HSMG-C197, or CMDA19AY7D1S.

Q: What is the impact of lens transparency (Diffused vs. Clear)?

A: The original BG1111C-TR features a Diffused lens, which scatters light over a wider viewing angle. The SML-310MTT86 features a Clear lens, which provides more directional light output. If your application requires the diffused light distribution of the original part, do not substitute with the SML-310MTT86. All other recommended substitutes maintain Diffused lens transparency.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts are available in 0603 (1608 Metric) surface mount package format, matching the original BG1111C-TR footprint. However, packaging options vary: VFHL1111C-4B23C-TR is supplied in Tape & Reel (TR); HSMG-C190, HSMG-C191, HSMG-C197, and SML-310MTT86 are supplied in Cut Tape (CT) & Digi-Reel®; CMDA19AY7D1S and CMDA19AG7D1S are supplied in Tape & Reel (TR). Verify packaging compatibility with your procurement and assembly processes.

Q: What are the Moisture Sensitivity Level (MSL) differences among substitutes?

A: MSL ratings vary: VFHL1111C-4B23C-TR (MSL 3, 168 Hours), HSMG-C190/C191/C197 (MSL 2A, 4 Weeks), CMDA19AY7D1S (MSL 2, 1 Year), CMDA19AG7D1S (MSL 1, Unlimited), and SML-310MTT86 (MSL 3, 168 Hours). Higher MSL numbers indicate greater moisture sensitivity and shorter shelf life after packaging opening. Select based on your assembly process timeline and storage conditions.

Q: Can I use the CMDA19AY7D1S as a direct substitute?

A: Yes. The CMDA19AY7D1S operates at 2.2V forward voltage (0.1V higher than the original), provides 15mcd brightness, and maintains Diffused lens transparency. The 170° viewing angle is wider than the original 153°/146°. This part is Active status and ROHS3 Compliant, making it suitable for new designs.
