Substitute Part Grouping Explanation

Substitution eligibility for the TLHP5102 is determined by the following critical parameters:

Primary Compatibility Criteria:

Color: Green
Lens Size: 5mm, T-1 3/4 form factor
Mounting Type: Through Hole, Radial package
Lens Transparency: Clear (colorless lens)
Forward Voltage Range: 2.1V to 2.4V (compatible with standard 20mA test current circuits)
Wavelength - Peak: 555nm to 575nm (green spectrum)

Secondary Considerations:

Millicandela Rating: 50mcd to 980mcd (brightness variation acceptable based on application requirements)
Viewing Angle: 16° to 40° (narrow to moderate viewing angles)
Height: 7.70mm to 13.20mm (mechanical fit within standard through-hole PCB layouts)
Product Status: Active or Not For New Designs (obsolete parts excluded from primary recommendations)
RoHS3 Compliance: Required for regulatory alignment

Substitute parts meeting these criteria maintain electrical and mechanical compatibility while accommodating design flexibility for brightness and viewing angle optimization.

Engineering Selection Recommendations

Primary Substitutes (Active Status, RoHS3 Compliant):

The LTL2P3KGKNN and LTL2R3KGKNN from Lite-On Inc. are the preferred substitutes for the TLHP5102. Both parts maintain T-1 3/4 form factor compatibility, operate within the acceptable forward voltage range (2.1V), and exceed the original brightness specification. LTL2P3KGKNN provides 980mcd at 22° viewing angle, while LTL2R3KGKNN delivers 680mcd at 30° viewing angle. Both are actively produced and fully RoHS3 compliant.

The LTL-4238 from Lite-On Inc. offers the closest brightness match to the TLHP5102 at 90mcd with a 16° viewing angle, making it suitable for applications requiring narrow-angle indication with minimal brightness variation.

Secondary Substitutes (Active Status, RoHS3 Compliant):

The SSL-LX5093SGC/B from Lumex Opto/Components Inc. provides 300mcd brightness at 2.2V forward voltage with 30° viewing angle. This part accommodates applications requiring higher brightness than the original specification while maintaining clear lens transparency and active product status.

The SSL-LX5093GC from Lumex offers lower brightness (50mcd) at 2.2V with 30° viewing angle, suitable for applications where reduced brightness is acceptable.

Not Recommended for New Designs:

The MV3450 (onsemi) and SLA-560MT3F (Rohm Semiconductor) are classified as obsolete or not for new designs, respectively. The MV3450 additionally lacks RoHS3 compliance. The 5219201F (Dialight) is a lamp replacement variant with different mechanical characteristics and should be evaluated only for specific incandescent replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the TLHP5102 be directly replaced with any of the listed substitutes?

A: Direct replacement is possible only with parts sharing identical forward voltage (2.4V) and brightness (133mcd) specifications. However, the LTL2P3KGKNN, LTL2R3KGKNN, LTL-4238, and SSL-LX5093SGC/B are electrically compatible within standard 20mA circuit designs due to their forward voltage range of 2.1V to 2.2V and T-1 3/4 form factor. Circuit validation is required when brightness differs significantly from the original 133mcd specification.

Q: What is the primary reason for substitution?

A: The TLHP5102 is classified as obsolete. Active production alternatives must be selected to ensure supply chain continuity and compliance with current manufacturing standards, particularly RoHS3 requirements.

Q: Are all substitute parts RoHS3 compliant?

A: All recommended substitutes (LTL2P3KGKNN, LTL2R3KGKNN, LTL-4238, SSL-LX5093GC, SSL-LX5093SGC/B, and 5219201F) are RoHS3 compliant. The MV3450 does not carry RoHS3 compliance and is not recommended for new designs.

Q: How do brightness differences affect circuit design?

A: The TLHP5102 operates at 133mcd. Substitute parts range from 50mcd to 980mcd. Higher brightness parts (LTL2P3KGKNN at 980mcd, SSL-LX5093SGC/B at 300mcd) may require current limiting resistor adjustment to prevent over-brightness or excessive power consumption. Lower brightness parts (SSL-LX5093GC at 50mcd, LTL-4238 at 90mcd) may require circuit verification to ensure adequate visibility.

Q: What is the impact of viewing angle variation?

A: The TLHP5102 features an 18° viewing angle. Substitute parts range from 16° to 40°. Narrower angles (16° to 22°) maintain similar directional indication characteristics. Wider angles (30° to 40°) provide broader visibility but may reduce peak brightness perception at direct viewing angles. Application requirements determine acceptable viewing angle ranges.

Q: Can the 5219201F (Dialight) be used as a direct substitute?

A: The 5219201F is designed as an incandescent lamp replacement with midget flange base compatibility. While electrically compatible (2.1V, 60mcd, green, T-1 3/4), its mechanical design differs from standard radial through-hole packages. Use only if the application specifically requires lamp replacement functionality.

Q: What forward voltage tolerance should be considered?

A: The TLHP5102 operates at 2.4V typical. Substitute parts operate at 2.1V to 2.3V typical. This 0.1V to 0.3V variation is within acceptable limits for standard LED indicator circuits using current-limiting resistors. Verify circuit design accommodates this range without exceeding maximum rated current (20mA test current).
