Engineering Selection Recommendations

Preferred Active Substitutes (Recommended for New Designs):

LTL2R3KGKNN and LTL2P3KGKNN from Lite-On Inc. are the primary recommended substitutes. Both parts maintain active product status, ROHS3 compliance, and operate within compatible voltage ranges (2.1V). LTL2R3KGKNN provides 680mcd brightness with 30° viewing angle, while LTL2P3KGKNN offers higher brightness at 980mcd with 22° viewing angle. Both are available in high inventory quantities.

SSL-LX5093SGC/B from Lumex Opto/Components Inc. provides 300mcd brightness at 2.2V with active product status and ROHS3 compliance, offering a mid-range brightness alternative with 30° viewing angle.

Secondary Active Substitutes:

LTL-4238 from Lite-On Inc. is suitable for applications requiring lower brightness (90mcd) with narrow 16° viewing angle, matching the TLHG5102's original viewing angle specification. This part operates at 2.1V with 10mA test current.

SSL-LX5093XGC from Lumex provides 250mcd brightness at 2.2V with 20° viewing angle, closely matching the TLHG5102's original 18° specification.

Obsolete Alternatives (Not Recommended for New Designs):

MV3450 from onsemi is obsolete and should not be selected for new production. The 4300H5LC from VCC is marked "Not For New Designs" and features diffused lens transparency and significantly lower brightness (2.3mcd), making it unsuitable as a direct replacement.

Compliance Verification:

All recommended active substitutes maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the TLHG5102's regulatory status.

Frequently Asked Questions (FAQ)

Q: Can LTL2R3KGKNN directly replace TLHG5102 in existing designs?

A: Yes. LTL2R3KGKNN is electrically compatible with forward voltage of 2.1V (compared to TLHG5102's 2.4V) and operates at the same 20mA test current. The 680mcd brightness is higher than the original 450mcd, which is acceptable in standard indicator applications. Physical dimensions are compatible with T-1 3/4 through-hole mounting.

Q: What is the brightness difference between TLHG5102 and available substitutes?

A: TLHG5102 provides 450mcd. Substitute options range from 50mcd (SSL-LX5093GC) to 980mcd (LTL2P3KGKNN). Selection depends on application requirements. For applications requiring similar brightness, SSL-LX5093SGC/B at 300mcd or SSL-LX5093XGC at 250mcd are closer matches.

Q: Are all substitutes ROHS3 compliant?

A: All recommended active substitutes (Lite-On and Lumex parts) are ROHS3 compliant. MV3450 from onsemi does not specify RoHS status and is obsolete. The 4300H5LC is ROHS3 compliant but marked "Not For New Designs."

Q: How do viewing angles differ among substitutes?

A: TLHG5102 has 18° viewing angle. Substitutes range from 16° (LTL-4238) to 60° (SSL-LX5093GW diffused variant). For narrow-angle applications, LTL-4238 at 16° or SSL-LX5093XGC at 20° are closest matches. For wider viewing angles, LTL2R3KGKNN at 30° is suitable.

Q: What is the voltage compatibility range for substitutes?

A: TLHG5102 operates at 2.4V forward voltage. Active substitutes operate between 2.1V and 2.2V, representing a 0.2V to 0.3V reduction. This is within acceptable tolerance for standard LED driver circuits and does not require circuit redesign.

Q: Can diffused lens variants substitute for the clear lens TLHG5102?

A: Diffused lens variants like SSL-LX5093GW or 4300H5LC are not direct replacements. Diffused lenses scatter light over wider angles (50° to 60°) and reduce brightness intensity, altering the optical characteristics of the original design. Use only if application requirements specifically allow diffused optics.

Q: Which substitute offers the closest electrical match to TLHG5102?

A: LTL2R3KGKNN provides the closest overall match with 2.1V forward voltage, 20mA test current, 565nm peak wavelength, and active product status. The 680mcd brightness is within acceptable range for indicator applications, and ROHS3 compliance matches the original specification.
