TLMD3100-GS08 Equivalent & Substitute Parts

Part Overview

The TLMD3100-GS08 is a red 648nm LED indication component in a 2-SMD, J-Lead surface mount package manufactured by Vishay Semiconductor Opto Division. This part is classified as obsolete, making identification of suitable substitutes essential for ongoing production and design requirements. The component delivers 20mcd luminous intensity at 10mA test current with a 1.8V forward voltage and 120° viewing angle. Due to its obsolete status, active equivalent parts from the same manufacturer are available to maintain design continuity and supply chain reliability.

Substitute Part Grouping Explanation

Substitution of the TLMD3100-GS08 is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

  • Wavelength - Dominant: 648nm
  • Wavelength - Peak: 650nm
  • Voltage - Forward (Vf) (Typ): 1.8V
  • Current - Test: 10mA
  • Viewing Angle: 120°
  • Lens Style: Round with Flat Top
  • Lens Size: 2.40mm Dia
  • Package / Case: 2-SMD, J-Lead
  • Size / Dimension: 3.00mm L x 2.80mm W
  • Height (Max): 1.85mm
  • Mounting Type: Surface Mount
  • RoHS Status: ROHS3 Compliant
  • Moisture Sensitivity Level (MSL): 2A (4 Weeks)

Allowable Variation:

  • Millicandela Rating: Substitutes may vary within the active product range while maintaining all other electrical and mechanical specifications
  • Product Status: Active substitutes are preferred over obsolete parts for supply chain continuity
  • Packaging Format: Tape & Reel (TR) packaging is acceptable for substitution purposes

Two active substitute parts meet these criteria: VLMD3100-GS08 (MFR Recommended) and VLMD3105-GS08 (Parametric Equivalent).

Engineering Selection Recommendations

VLMD3100-GS08 is designated as the MFR Recommended substitute. This part maintains identical electrical and mechanical specifications to the TLMD3100-GS08 with the exception of millicandela rating (11.2mcd versus 20mcd). The VLMD3100-GS08 carries active product status, ensuring ongoing manufacturer support, availability, and compliance with current RoHS3 and REACH requirements. This part is suitable for applications where the reduced luminous intensity is acceptable within circuit design parameters.

VLMD3105-GS08 is classified as a Parametric Equivalent substitute. This part matches all electrical and mechanical specifications of the TLMD3100-GS08, including the 20mcd millicandela rating. The VLMD3105-GS08 is also active product status with full RoHS3 and REACH compliance. This part is suitable for applications requiring identical luminous intensity performance to the original component.

Both substitutes are manufactured by Vishay Semiconductor Opto Division and are available in Tape & Reel packaging format. Selection between the two substitutes depends on luminous intensity requirements: VLMD3105-GS08 for direct performance matching, or VLMD3100-GS08 for alternative intensity applications.

Frequently Asked Questions (FAQ)

Q: Can VLMD3100-GS08 and VLMD3105-GS08 be used interchangeably with TLMD3100-GS08?

A: Both parts are electrically and mechanically compatible substitutes. The primary difference is millicandela rating: VLMD3100-GS08 provides 11.2mcd while VLMD3105-GS08 provides 20mcd (matching the original). Selection depends on circuit brightness requirements.

Q: What is the significance of the millicandela rating difference?

A: Millicandela rating determines luminous intensity output at the specified test current (10mA). VLMD3105-GS08 maintains the original 20mcd specification, while VLMD3100-GS08 operates at 11.2mcd. Circuit design must accommodate the selected intensity level.

Q: Are both substitutes available in the same packaging format as the original?

A: The TLMD3100-GS08 packaging format is not specified in the original data. Both substitutes are supplied in Tape & Reel (TR) format, which is standard for surface mount production environments.

Q: Do the substitutes maintain compliance certifications?

A: Both VLMD3100-GS08 and VLMD3105-GS08 are ROHS3 Compliant and REACH Unaffected, matching the original part's compliance status.

Q: Why is the TLMD3100-GS08 classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The active substitutes from the VLM.3 series provide equivalent functionality with ongoing manufacturer support and supply availability.

Q: Are there any differences in moisture sensitivity or handling requirements?

A: Both substitutes maintain the same Moisture Sensitivity Level (MSL) rating of 2A (4 Weeks) as the original part, requiring identical storage and handling procedures.
