Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLMP3100-GS08 are classified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Electrical Parameters: Forward voltage (Vf), test current, wavelength characteristics (dominant and peak), and brightness rating (millicandela).

Mechanical Parameters: Package type (2-SMD, J-Lead / 2-PLCC), lens configuration (Round with Flat Top), lens size (2.40mm Dia), physical dimensions, and mounting type (Surface Mount).

Compliance Parameters: RoHS3 compliance, REACH status, and MSL rating.

The substitute parts are organized into two categories:

Parametric Equivalents (Vishay VLM.3 Series): Parts that maintain identical or near-identical electrical and mechanical specifications with active product status.

Manufacturer Recommended Substitute (Everlight Electronics): A cross-manufacturer alternative with different package geometry and enhanced brightness characteristics, suitable for applications where form factor differences are acceptable.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred):

VLMP3100-GS08 is the primary substitute for TLMP3100-GS08. Both components are manufactured by Vishay Semiconductor Opto Division and maintain identical electrical specifications (2.1V forward voltage, 10mA test current, 560nm dominant wavelength, 4mcd brightness). The mechanical package, dimensions, and compliance certifications are equivalent. VLMP3100-GS08 carries active product status with confirmed inventory availability, ensuring long-term supply continuity. This part requires no circuit redesign or PCB layout modification.

VLMP31G2J1-GS08 provides an alternative within the Vishay VLM.3 series. This part maintains identical package geometry and electrical test parameters but features a 565nm dominant wavelength (compared to 560nm in the original). The wavelength shift of 5nm falls within the green LED spectrum range and is suitable for applications where precise wavelength matching is not critical. Active product status and equivalent compliance certifications support its use as a secondary substitute.

For Cross-Manufacturer Substitution:

The Everlight Electronics 67-11/GHC-AT2V1/2T represents a manufacturer-recommended alternative with significant design considerations. This part maintains the 2.40mm lens diameter, 120° viewing angle, and green color specification. However, the package geometry differs (1411 / 3528 Metric versus 2-PLCC), resulting in reduced height (0.80mm versus 1.85mm) and increased length (4.60mm versus 3.00mm). The brightness rating is substantially higher at 630mcd compared to 4mcd, and the dominant wavelength is 527nm (blue-shifted from 560nm). Forward voltage and test current specifications are not provided. This substitute is suitable only for applications where PCB layout can accommodate the different footprint and where the enhanced brightness and wavelength shift do not conflict with system requirements.

Frequently Asked Questions (FAQ)

Q: Can VLMP3100-GS08 be used as a direct replacement for TLMP3100-GS08?

A: Yes. VLMP3100-GS08 is a direct parametric equivalent manufactured by the same supplier (Vishay Semiconductor Opto Division). Electrical specifications (2.1V forward voltage, 10mA test current, 560nm wavelength, 4mcd brightness), package type (2-SMD, J-Lead / 2-PLCC), physical dimensions (3.00mm L x 2.80mm W x 1.85mm H), and compliance certifications are identical. No circuit or PCB modifications are required.

Q: What is the difference between VLMP31G2J1-GS08 and VLMP3100-GS08?

A: Both parts are Vishay VLM.3 series components with identical package geometry, forward voltage (2.1V), test current (10mA), and brightness rating (4mcd). The primary difference is the dominant wavelength: VLMP31G2J1-GS08 operates at 565nm compared to 560nm for VLMP3100-GS08. This 5nm shift remains within the green LED spectrum and does not affect mechanical compatibility or electrical performance in standard indication applications.

Q: Why is the Everlight 67-11/GHC-AT2V1/2T listed as a substitute if the package is different?

A: The Everlight part is classified as a manufacturer-recommended substitute based on functional equivalence (green LED indicator with 120° viewing angle and 2.40mm lens diameter). However, the package geometry differs significantly: the 1411 (3528 Metric) package is 4.60mm long and 0.80mm tall, compared to the 2-PLCC package at 3.00mm long and 1.85mm tall. This substitute is suitable only for designs where the PCB footprint can be modified to accommodate the different dimensions and where the higher brightness (630mcd) and shorter wavelength (527nm) are acceptable.

Q: Are all substitute parts RoHS3 compliant?

A: VLMP3100-GS08 and VLMP31G2J1-GS08 are confirmed ROHS3 compliant with 2A MSL rating (4 Weeks). The Everlight 67-11/GHC-AT2V1/2T compliance specifications are not provided in the available data. Verification with the manufacturer is required before selection for applications with specific compliance requirements.

Q: What inventory status should I consider when selecting a substitute?

A: VLMP3100-GS08 has 1000 pieces in stock, VLMP31G2J1-GS08 has 816 pieces in stock, and the Everlight part has 960 pieces in stock. All substitutes demonstrate adequate inventory availability for production continuity. The original TLMP3100-GS08 (719 pieces) is obsolete and should not be selected for new designs.
