Engineering Selection Recommendations

Tier 1 - Direct Electrical Equivalents (Recommended Primary Substitutes):

The 3GD-F (Bivar Inc.) provides the closest electrical match to the 3PGD-F. Both components share identical forward voltage (2.1V vs. 2.2V), test current (20mA), viewing angle (35°), and physical height (5.30mm). The 3GD-F is manufactured by the same supplier, carries active product status, and holds ROHS3 compliance. The increased brightness rating (25mcd vs. 5mcd) is acceptable for indication applications where higher visibility is beneficial. This part is the preferred substitute for direct replacement in existing designs.

The 151031VS06000 (Würth Elektronik, WL-TMRC series) matches the 3PGD-F in forward voltage (2.2V), test current (20mA), and physical form factor. This component is active, ROHS3 compliant, and offers higher brightness (30mcd) with a wider viewing angle (60°). The wavelength peak (560nm) remains within the green spectrum. This part is suitable for applications requiring enhanced visibility or wider beam distribution.

Tier 2 - Extended Spectrum Alternatives (Yellow-Green Options):

The 264-7SYGD/S530-E2 (Everlight Electronics) operates at 2.0V forward voltage with 20mA test current, maintaining electrical compatibility with the 3PGD-F. This component features significantly higher brightness (50mcd) and operates in the yellow-green spectrum (575nm peak wavelength). The part is active and ROHS3 compliant. Selection of this part requires confirmation that yellow-green optical output is acceptable for the application.

The 414SYGD/S530-E2 (Everlight Electronics) provides a wide-angle alternative (140° viewing angle) in yellow-green spectrum. This part operates at 2.0V with 20mA test current but features lower brightness (12.5mcd) and increased height (7.00mm). This option is suitable only for applications requiring exceptionally wide light distribution and where yellow-green color is acceptable.

Tier 3 - Higher Voltage Alternatives (5V and 12V Options):

The HLMP-1640 series (Broadcom Limited) operates at 5.0V forward voltage with 10mA test current. These parts are active and ROHS3 compliant but require circuit redesign for voltage compatibility. The HLMP-1640-B00A1 and HLMP-1640-B00A2 variants feature right-angle mounting, which differs from the radial configuration of the 3PGD-F. Selection of these parts is limited to applications with 5V supply voltage and where mounting orientation can be accommodated.

The HLMP-1641 (Broadcom Limited) operates at 12.0V forward voltage with 13mA test current. This part is active and ROHS3 compliant but requires significant circuit redesign. Selection is limited to 12V supply applications only.

Tier 4 - Low-Current Alternatives (1.9V Options):

The HLMP-1790 and HLMP-1790-A0002 (Broadcom Limited) operate at 1.9V forward voltage with only 2mA test current. These parts are active and ROHS3 compliant but feature significantly lower brightness (2.3mcd) compared to the 3PGD-F (5mcd). These options are suitable only for ultra-low-power applications where reduced brightness is acceptable.

Compliance and Regulatory Status:

All recommended substitutes carry ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with modern manufacturing requirements. The 3PGD-F obsolete status necessitates transition to active product alternatives for ongoing production support and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 3GD-F directly replace the 3PGD-F without circuit modification?

A: Yes. The 3GD-F operates at 2.1V forward voltage compared to the 3PGD-F at 2.2V, a difference within typical circuit tolerance. Both components share identical test current (20mA), viewing angle (35°), and physical dimensions (5.30mm height). No circuit redesign is required. The increased brightness (25mcd vs. 5mcd) is compatible with indication applications.

Q: What is the difference between the 3PGD-F and 151031VS06000 in terms of optical performance?

A: Both components operate at 2.2V forward voltage and 20mA test current. The primary optical difference is viewing angle: the 3PGD-F provides 35° while the 151031VS06000 provides 60°. The 151031VS06000 offers wider light distribution, suitable for applications requiring visibility from broader angles. Wavelength peaks are similar (555nm vs. 560nm), both within the green spectrum.

Q: Why do some substitutes operate at 5V or 12V when the 3PGD-F operates at 2.2V?

A: The HLMP-1640 (5V) and HLMP-1641 (12V) series are designed for different supply voltage applications. These parts require circuit redesign including modified current-limiting resistor values. Selection of these parts is appropriate only when the application circuit operates at 5V or 12V supply voltage. Direct substitution without circuit modification will result in component failure.

Q: Are yellow-green LED substitutes (264-7SYGD/S530-E2, 414SYGD/S530-E2) compatible with the 3PGD-F?

A: Yellow-green LEDs operate at compatible forward voltages (2.0V) and test currents (20mA), making them electrically compatible. However, the optical output color differs from the original green specification. Selection of yellow-green substitutes requires confirmation that the application can accept yellow-green indication instead of pure green. Wavelength shift from 555nm (green) to 575nm (yellow-green) may affect visual perception and color-coding requirements.

Q: What is the significance of the HLMP-1790 low-current option?

A: The HLMP-1790 operates at 1.9V forward voltage with only 2mA test current, compared to the 3PGD-F at 2.2V and 20mA. This part is designed for ultra-low-power applications where reduced current consumption is critical. The brightness rating (2.3mcd) is lower than the 3PGD-F (5mcd). This option is suitable only for applications where reduced power consumption justifies lower brightness.

Q: How do packaging options (Bulk, Tape & Reel, Cut Tape) affect substitution?

A: Packaging format affects supply chain and assembly processes but does not impact electrical or optical performance. The 3PGD-F is supplied in Bulk packaging. Substitutes are available in Bulk, Tape & Reel (TR), or Cut Tape (CT) formats. Selection of packaging format depends on production volume and assembly equipment compatibility. All packaging formats contain identical components with identical electrical specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Most recommended substitutes carry ROHS3 compliance certification. The 414SYGD/S530-E2 does not list ROHS status in the provided specifications. Verification of ROHS compliance status is required for applications subject to ROHS regulatory requirements. All Broadcom Limited parts (HLMP series) and the Würth Elektronik 151031VS06000 are confirmed ROHS3 compliant.

Q: What is the maximum height difference between the 3PGD-F and substitute parts?

A: The 3PGD-F has a maximum height of 5.30mm. Substitute parts range from 5.30mm to 7.00mm maximum height. The 414SYGD/S530-E2 reaches 7.00mm, a 1.70mm increase. Height differences may affect PCB clearance and component spacing. Verification of available vertical clearance is required before selecting substitutes with increased height specifications.

Q: Can the HLMP-1640-B00A1 and HLMP-1640-B00A2 right-angle variants replace the radial 3PGD-F?

A: The HLMP-1640-B00A1 and HLMP-1640-B00A2 feature right-angle mounting configuration, while the 3PGD-F uses radial (straight) lead configuration. These variants are mechanically incompatible with PCB through-hole patterns designed for radial leads. Selection of right-angle variants requires PCB redesign to accommodate the different lead orientation. These parts are suitable only for new designs where right-angle mounting is specified.
