Engineering Selection Recommendations

The VLMS20H2L1-GS08 is the qualified substitute for the obsolete TLMS2100-GS08. Selection is based on the following engineering criteria:

Product Status: The VLMS20H2L1-GS08 maintains Active product status with Vishay Semiconductor Opto Division, ensuring ongoing availability, technical support, and supply chain continuity compared to the obsolete TLMS2100-GS08.

Regulatory Compliance: Both components maintain ROHS3 Compliance and REACH Unaffected status, meeting current environmental and regulatory requirements for electronic component procurement and deployment.

Mechanical Interchangeability: Identical package configuration (2-SMD, J-Lead), physical dimensions (2.20mm L x 1.40mm W, 1.40mm maximum height), lens geometry (Rectangle with Flat Top, 1.50mm x 0.90mm), and surface mount mounting type ensure direct PCB compatibility without layout modifications.

Optical Performance: Both components operate in the red spectrum with identical viewing angle (120°) and clear lens transparency. The dominant wavelength shift from 628nm to 630nm remains within the red indicator specification range, maintaining visual consistency in indication applications.

Electrical Characteristics: The VLMS20H2L1-GS08 operates at lower forward voltage (1.8V versus 2.1V) and reduced test current (2mA versus 10mA), resulting in improved power efficiency. The increased brightness rating (9mcd versus 7.5mcd) provides enhanced visibility margin for indication purposes.

Environmental Handling: Identical Moisture Sensitivity Level (2A, 4 Weeks) ensures equivalent storage, handling, and assembly process requirements.

Frequently Asked Questions (FAQ)

Q: Can the VLMS20H2L1-GS08 be used as a direct replacement for the TLMS2100-GS08 on existing PCBs?

A: Yes. The VLMS20H2L1-GS08 is mechanically and electrically compatible for direct substitution. Identical package type, physical dimensions, lens configuration, and mounting type ensure PCB compatibility without layout changes. The lower forward voltage and reduced test current may improve circuit efficiency.

Q: What are the key differences between these two parts?

A: The primary differences are product status (Obsolete versus Active), forward voltage (2.1V versus 1.8V), test current (10mA versus 2mA), brightness rating (7.5mcd versus 9mcd), and dominant wavelength (628nm versus 630nm). All differences remain within acceptable parameters for red LED indication applications.

Q: Does the wavelength shift from 628nm to 630nm affect visual appearance?

A: No. Both wavelengths fall within the red spectrum and are visually indistinguishable in indication applications. The shift of 2nm is imperceptible to human vision in LED indicator contexts.

Q: Are there any circuit design modifications required when switching to the VLMS20H2L1-GS08?

A: The lower forward voltage (1.8V versus 2.1V) and reduced test current (2mA versus 10mA) may allow for simplified current-limiting resistor calculations, potentially reducing power consumption. Existing circuits designed for the TLMS2100-GS08 will function with the VLMS20H2L1-GS08 without modification, though optimization is possible.

Q: What is the packaging difference between these parts?

A: The TLMS2100-GS08 is supplied in standard packaging, while the VLMS20H2L1-GS08 is supplied in Tape & Reel (TR) format. Both use identical 2-SMD, J-Lead package configuration suitable for automated assembly.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the TLMS2100-GS08 and VLMS20H2L1-GS08 maintain ROHS3 Compliance and REACH Unaffected status, meeting current environmental and regulatory requirements.
