TLHB5100 Equivalent & Substitute Parts

Part Overview

The TLHB5100 is a blue LED indicator manufactured by Vishay Semiconductor Opto Division, configured as a 5mm T-1 3/4 through-hole radial component with 250mcd brightness and 3.9V forward voltage. This part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. Substitute parts must maintain compatibility with through-hole mounting, 5mm form factor, and blue LED indication functionality while meeting current RoHS3 and REACH compliance standards.

Engineering Selection Recommendations

All listed substitute parts carry active product status and maintain ROHS3 compliance, ensuring long-term availability and regulatory conformance. The TLHB5100 obsolete status necessitates migration to active alternatives.

Direct Form Factor Match (5mm T-1 3/4 Clear Lens): 5UBWC-0.6K, CMD383UBC/H2, SSL-LX5093SBC/A, SSL-LX5093TSBC, SSL-LX5093XSBC/A, and SSL-LX5093XSBC/B maintain identical 5mm T-1 3/4 through-hole radial configuration with clear lens transparency. Forward voltage ranges from 3.8V to 5V across these options.

Alternative Form Factor (4.90mm Diffused Lens): 151051BS04000 provides a diffused lens variant with slightly reduced diameter and lower forward voltage (3.2V), suitable for applications requiring wider viewing angle (40°) and higher brightness (500mcd).

Diffused Lens Option (5mm T-1 3/4): SSL-LX5093USBD offers diffused lens transparency with 5mm T-1 3/4 form factor, 4.6V forward voltage, and 60° viewing angle, providing maximum light distribution for non-directional indication applications.

Frequently Asked Questions (FAQ)

Q: Can I use SSL-LX5093USBD as a direct replacement for TLHB5100?

A: SSL-LX5093USBD maintains 5mm T-1 3/4 through-hole radial configuration and blue color. However, it features diffused lens transparency versus the TLHB5100's clear lens, resulting in 60° viewing angle versus 18°. Forward voltage is 4.6V versus 3.9V. Circuit design must accommodate these parameter differences.

Q: What is the primary difference between 5UBWC-0.6K and CMD383UBC/H2?

A: Both parts share 5mm T-1 3/4 clear lens configuration and 3.8V forward voltage. CMD383UBC/H2 provides higher brightness (630mcd versus 600mcd) and narrower viewing angle (30° versus 35°). Selection depends on brightness and viewing angle requirements.

Q: Why does 151051BS04000 have a different lens size (4.90mm)?

A: 151051BS04000 is classified as a 4.90mm diameter component versus the standard 5mm T-1 3/4 form factor. This minor dimensional variation may affect mechanical fit in PCB mounting holes designed for 5mm components. Verify mechanical compatibility before selection.

Q: Which substitute offers the closest electrical match to TLHB5100?

A: SSL-LX5093USBD provides the closest forward voltage match at 4.6V versus the TLHB5100's 3.9V. 5UBWC-0.6K and CMD383UBC/H2 both operate at 3.8V, also within close tolerance. All three maintain 20mA test current specification.

Q: Are all substitute parts RoHS3 compliant?

A: All listed substitute parts carry ROHS3 Compliant status, ensuring regulatory conformance for new designs and production environments requiring RoHS3 certification.

Q: What viewing angle options are available?

A: Viewing angles range from 10° (SSL-LX5093XSBC/B) to 60° (SSL-LX5093USBD). The TLHB5100 original specification is 18°. Selection should match application requirements for light distribution and visibility.
