Engineering Selection Recommendations

For Direct Replacement (Same Manufacturer - Stanley Electric Co):

VFHD1111C-3B72B-TR is the manufacturer-recommended substitute. This part maintains the same 0603 package, surface mount configuration, and diffused lens transparency. The forward voltage is slightly lower (1.9V vs 2.1V), and the brightness is significantly higher (43mcd vs 6.4mcd). This part carries Active product status and ROHS3 compliance, providing long-term availability and regulatory support.

RPG1111C-11-TR offers an alternative within the same manufacturer family. It maintains identical forward voltage (2.1V) and wavelength (567nm) as the original PG1111C-TR, with slightly higher brightness (9.8mcd). However, this part is also classified as Obsolete, limiting its suitability for new designs requiring long-term component availability.

For Cross-Manufacturer Substitution (Active Status Preferred):

Parts with Active product status are recommended for applications requiring long-term production support and component availability:

HSMG-C190 (Broadcom Limited): Closest electrical match with 2.2V forward voltage, 15mcd brightness, and 572nm wavelength. Diffused lens transparency matches the original. MSL rating of 2A provides adequate moisture protection.
CMDA19AY7D1S (Visual Communications Company): Offers 2.2V forward voltage with 15mcd brightness and diffused lens. Superior viewing angle of 170° compared to original 150°. MSL rating of 2 (1 Year) is acceptable for standard applications.
5988070102F or 5988070107F (Dialight): Provide close electrical match at 2V forward voltage with 20mcd brightness and 568nm wavelength. Clear lens transparency differs from original diffused lens. Height is slightly reduced (0.70mm vs 0.80mm). Both carry Active status and ROHS3 compliance.

For Applications Requiring Higher Brightness:

5988081102F or 5988081107F (Dialight): Deliver 300mcd brightness at 3.2V forward voltage with 523nm wavelength. Suitable for applications where increased visibility is required. Clear lens transparency and reduced height (0.70mm) must be evaluated for optical and mechanical fit.
150060GS75000 (Würth Elektronik): Provides highest brightness at 430mcd with 3.2V forward voltage and 520nm wavelength. Clear lens and reduced height require mechanical verification.

Regulatory and Compliance Considerations:

All substitute parts listed carry REACH Unaffected status, matching the original component. All active-status alternatives are ROHS3 compliant, providing regulatory alignment for current manufacturing standards. The original PG1111C-TR does not specify RoHS status; substitution with ROHS3-compliant parts ensures compliance with current environmental regulations.

Frequently Asked Questions (FAQ)

Q1: Can VFHD1111C-3B72B-TR directly replace PG1111C-TR in existing designs?

VFHD1111C-3B72B-TR is electrically compatible as a substitute. The forward voltage is 1.9V (vs 2.1V original), requiring circuit verification to ensure proper current limiting. The brightness increase from 6.4mcd to 43mcd may affect visual perception in the application. The wavelength shift from 567nm to 572nm (yellow-green) is within the green spectrum but may be visually distinguishable. Mechanical fit is identical (0603 package, 0.80mm height). This part is recommended by the manufacturer and carries Active status for long-term availability.

Q2: What is the difference between diffused and clear lens transparency in these LEDs?

Diffused lens transparency scatters light over a wider area, providing more uniform brightness across the viewing angle but lower peak brightness in any single direction. Clear lens transparency concentrates light in a more focused beam, providing higher brightness in the direct viewing direction but narrower effective viewing angle. The original PG1111C-TR uses diffused lens. Substitutes with clear lens (Dialight, Würth Elektronik) will appear brighter but with more directional light output. Diffused alternatives (HSMG-C190, CMDA19AY7D1S) maintain the original optical characteristic.

Q3: Why do some substitutes have different forward voltages?

Forward voltage (Vf) varies based on LED chip design, semiconductor material composition, and manufacturing process. Variations from 1.9V to 3.4V across the substitute list reflect different LED technologies. For circuit compatibility, the current-limiting resistor must be recalculated based on the actual forward voltage of the selected substitute. A 2.1V part and a 3.2V part in the same circuit with identical resistor values will draw different currents.

Q4: Is the 0.70mm height of Dialight parts compatible with the 0.80mm original?

Yes, the 0.70mm height is mechanically compatible. The original PG1111C-TR specifies 0.80mm maximum height; Dialight parts at 0.70mm are within tolerance and will fit in the same PCB footprint. The reduced height may provide slight mechanical advantages in space-constrained designs. No PCB redesign is required for height difference.

Q5: What does MSL (Moisture Sensitivity Level) mean for component substitution?

MSL indicates the maximum time a component can be stored in ambient conditions (typically 30°C, 60% relative humidity) before requiring baking before reflow soldering. The original PG1111C-TR specifies MSL 4 (72 hours). Most active substitutes specify MSL 3 (168 hours) or MSL 2A (4 weeks), providing longer shelf life and more flexible handling. Lower MSL numbers indicate better moisture tolerance. Substitution with lower MSL numbers (better performance) is acceptable; substitution with higher MSL numbers requires verification of storage and handling procedures.

Q6: Can I use a 3.2V LED substitute in a circuit designed for 2.1V?

No, direct substitution is not recommended without circuit modification. A 3.2V LED requires approximately 1.1V additional voltage drop across the current-limiting resistor compared to a 2.1V LED. In a fixed-voltage circuit, this will significantly reduce LED current and brightness. The resistor value must be recalculated for the new forward voltage. Alternatively, verify that the circuit power supply and resistor design can accommodate the higher voltage requirement.

Q7: Which substitute offers the closest match to the original PG1111C-TR?

HSMG-C190 (Broadcom Limited) provides the closest electrical and optical match: 2.2V forward voltage (vs 2.1V original), 15mcd brightness (vs 6.4mcd original), 572nm wavelength (vs 567nm original), diffused lens (matching original), and 0.80mm height (identical to original). The primary differences are slightly higher brightness and wavelength shift within the green spectrum. This part carries Active status and ROHS3 compliance for long-term availability.

Q8: Are there packaging differences between the substitutes?

Yes. The original PG1111C-TR specifies packaging as "-" (not specified). Substitutes are available in multiple packaging formats: Cut Tape (CT) & Digi-Reel®, Tape & Reel (TR), Strip, and Chip LED. For production assembly, Tape & Reel (TR) packaging is standard for automated pick-and-place equipment. Cut Tape (CT) & Digi-Reel® is suitable for lower-volume manual assembly. Strip packaging is typically for manual assembly in smaller quantities. Verify packaging compatibility with your assembly process before selection.

Q9: Do all substitutes meet REACH and RoHS requirements?

All substitutes listed carry REACH Unaffected status, matching the original component. All active-status substitutes (VFHD1111C-3B72B-TR, 150060GS75000, Dialight series, CMDA19 series, HSMG-C190) are ROHS3 compliant. The original PG1111C-TR does not specify RoHS status. Substitution with ROHS3-compliant parts ensures compliance with current environmental regulations for new designs and manufacturing.

Q10: What is the inventory status of these substitutes?

Current inventory levels are: VFHD1111C-3B72B-TR (1,627 pcs), RPG1111C-11-TR (1,604 pcs), 150060GS75000 (19,874 pcs), 5988070102F (3,589 pcs), 5988070107F (1,404 pcs), 5988081102F (2,362 pcs), 5988081107F (55,797 pcs), CMDA19AG7D1S (4,870 pcs), CMDA19AY7D1S (10,556 pcs), HSMG-C190 (155,400 pcs).
