Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLMY3102-GS08 are classified based on alignment with the following critical parameters:

Primary Substitution Criteria:

• Color: Yellow
• Wavelength - Dominant: 588nm or 585nm (amber-yellow acceptable)
• Package / Case: 2-SMD, J-Lead or 2-PLCC
• Mounting Type: Surface Mount
• Lens Style: Round with Flat Top
• Viewing Angle: 120°
• RoHS Status: ROHS3 Compliant

Substitution Categories:

1. MFR Recommended Equivalent (VLMY3102-GS08): Direct functional equivalent from Vishay with identical electrical specifications and active product status.

2. Parametric Equivalent (VLMY30J2M1-GS08): Vishay component with compatible wavelength and package but different forward voltage (1.8V vs 2.1V) and test current (2mA vs 10mA), resulting in higher brightness output (14mcd vs 13.15mcd).

3. Cross-Manufacturer Substitute (HSMY-A100-J00J1): Broadcom component with compatible wavelength range (585nm peak), similar package footprint, and active status. Forward voltage is 2.2V with 20mA test current and 12mcd brightness.

Parameter Comparison

Engineering Selection Recommendations

VLMY3102-GS08 (Primary Recommendation): This Vishay component is the manufacturer-recommended equivalent with active product status. It maintains identical electrical specifications (2.1V forward voltage, 10mA test current) and mechanical dimensions as the obsolete TLMY3102-GS08. Both components share the same wavelength characteristics (588nm dominant, 585nm peak) and package configuration. This part is suitable for direct replacement in existing designs without circuit modification. Inventory availability is significantly higher (15,600 pcs) compared to the main part.

VLMY30J2M1-GS08 (Parametric Equivalent): This Vishay alternative operates at lower forward voltage (1.8V) and test current (2mA) while delivering higher brightness (14mcd). Circuit design must accommodate the different electrical operating point. This part is appropriate for applications where reduced power consumption is beneficial and brightness variation is acceptable. Product status is active with moderate inventory (813 pcs).

HSMY-A100-J00J1 (Cross-Manufacturer Option): The Broadcom component provides wavelength compatibility (585nm peak) and maintains the 120° viewing angle. Physical dimensions differ slightly (3.20mm L vs 3.00mm L, 2.10mm H vs 1.85mm H), requiring PCB layout verification. Forward voltage is 2.2V at 20mA test current. This option is suitable when Vishay components are unavailable and PCB space permits the dimensional variation. Product status is active with adequate inventory (2,100 pcs).

All substitute parts maintain ROHS3 compliance and identical moisture sensitivity ratings (2A, 4 Weeks).

Frequently Asked Questions (FAQ)

Q: Can VLMY3102-GS08 be used as a direct replacement for TLMY3102-GS08?

A: Yes. VLMY3102-GS08 is the manufacturer-recommended equivalent with identical electrical specifications, wavelength characteristics, and package dimensions. No circuit modifications are required.

Q: What are the key differences between VLMY30J2M1-GS08 and the main part?

A: VLMY30J2M1-GS08 operates at 1.8V forward voltage with 2mA test current, compared to 2.1V and 10mA for TLMY3102-GS08. This results in higher brightness output (14mcd vs 13.15mcd) and lower power consumption. Circuit design must be adjusted to accommodate the different electrical operating point.

Q: Is HSMY-A100-J00J1 compatible with the original PCB layout?

A: HSMY-A100-J00J1 has slightly larger dimensions (3.20mm L x 2.80mm W x 2.10mm H vs 3.00mm L x 2.80mm W x 1.85mm H). PCB layout verification is required to confirm clearance and mounting compatibility. The package type differs (2-PLCC vs 2-SMD, J-Lead), which may affect footprint compatibility.

Q: Are all substitute parts RoHS compliant?

A: Yes. VLMY3102-GS08, VLMY30J2M1-GS08, and HSMY-A100-J00J1 are all ROHS3 compliant with identical moisture sensitivity levels (2A, 4 Weeks).

Q: Which substitute part has the best inventory availability?

A: VLMY3102-GS08 has the highest inventory (15,600 pcs), followed by HSMY-A100-J00J1 (2,100 pcs) and VLMY30J2M1-GS08 (813 pcs).

Q: Can VLMY30J2M1-GS08 be used in applications requiring 10mA test current?

A: VLMY30J2M1-GS08 is specified for 2mA test current. Use in higher current applications requires circuit analysis to ensure the component operates within safe electrical limits and delivers acceptable brightness performance.

Q: What wavelength range is acceptable for yellow LED substitution?

A: The substitute parts maintain dominant wavelengths between 585nm and 588nm, which are within the yellow spectrum. HSMY-A100-J00J1 at 585nm peak wavelength is classified as amber-yellow and provides acceptable color compatibility for indication applications.
