Engineering Selection Recommendations

All substitute parts listed are ROHS3 compliant and carry active product status, ensuring long-term availability and regulatory compliance. Selection among substitutes depends on circuit voltage tolerance and optical requirements:

For 3.2V to 3.9V circuits: 151051BS04000, 5UBWC-0.6K, CMD383UBC/H2, and SSL-LX5093USBD are compatible. The 151051BS04000 and SSL-LX5093USBD feature diffused lenses for wider light distribution, while 5UBWC-0.6K and CMD383UBC/H2 maintain clear lens characteristics similar to the original TLHB5102.

For 4.5V to 5V circuits: SSL-LX5093SBC/A, SSL-LX5093TSBC, SSL-LX5093XSBC/A, and SSL-LX5093XSBC/B are suitable. These parts accommodate higher forward voltage requirements while maintaining the 5mm T-1 3/4 package form factor.

For brightness matching: CMD383UBC/H2 (630mcd) and 5UBWC-0.6K (600mcd) provide the highest brightness levels. SSL-LX5093USBD (300mcd) and SSL-LX5093TSBC (400mcd) offer mid-range brightness. SSL-LX5093SBC/A (100mcd) is suitable for applications requiring lower brightness.

For viewing angle requirements: SSL-LX5093USBD provides the widest viewing angle at 60°, suitable for applications requiring broad light distribution. SSL-LX5093XSBC/B offers the narrowest viewing angle at 10° for focused indication.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different forward voltage in my existing circuit?

A: Forward voltage differences require circuit redesign. The TLHB5102 operates at 3.9V. Substitutes range from 3.2V to 5V. If your circuit is designed for 3.9V, select substitutes within the 3.2V to 3.9V range (151051BS04000, 5UBWC-0.6K, CMD383UBC/H2, SSL-LX5093USBD) to maintain proper current limiting and brightness. Higher voltage parts (4.5V to 5V) require resistor recalculation.

Q: What is the difference between clear and diffused lens options?

A: Clear lens parts (5UBWC-0.6K, CMD383UBC/H2, SSL-LX5093 series clear variants) provide focused light output with narrower viewing angles. Diffused lens parts (151051BS04000, SSL-LX5093USBD) scatter light over wider angles, suitable for applications requiring broader visibility. The TLHB5102 features a clear lens; select diffused substitutes only if your application tolerates wider light distribution.

Q: Are all substitute parts mechanically compatible with the TLHB5102 footprint?

A: All listed substitutes use the same 5mm T-1 3/4 through-hole radial package. However, height varies from 8.50mm to 13.10mm. The TLHB5102 has a maximum height of 13.10mm. Most substitutes are shorter (8.50mm to 8.95mm), which is compatible with standard PCB layouts. Verify clearance in your specific application if height-constrained.

Q: Which substitute offers the closest electrical match to the TLHB5102?

A: 5UBWC-0.6K (3.8V forward voltage, 600mcd brightness) and CMD383UBC/H2 (3.8V forward voltage, 630mcd brightness) provide the closest forward voltage match to the TLHB5102 (3.9V). Both are active products with high inventory availability and clear lens characteristics.

Q: Can I use SSL-LX5093USBD as a direct replacement?

A: SSL-LX5093USBD is electrically compatible (4.6V forward voltage within acceptable range) and mechanically compatible (5mm T-1 3/4 package). However, it features a diffused blue lens compared to the TLHB5102's clear lens, resulting in wider viewing angle (60° vs. 18°) and different optical appearance. Use this substitute only if your application accepts diffused light output.
