Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLMH3102-GS08 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Package / Case: 2-SMD, J-Lead or 2-PLCC (mechanically compatible footprints)
• Mounting Type: Surface Mount
• Lens Transparency: Clear
• Viewing Angle: 120°
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 2A (4 Weeks)

Secondary Compatibility Criteria:

• Color: Red (primary specification)
• Wavelength - Peak: 635nm (acceptable range for red LEDs)
• Voltage - Forward (Vf): 2V nominal (±0.2V tolerance acceptable for circuit design)
• Millicandela Rating: 13.15mcd (±2mcd variance acceptable for indication applications)

Identified Substitute Parts:

1. VLMH3102-GS08 (Vishay Semiconductor Opto Division) - MFR Recommended substitute with active product status. Amber color variant with equivalent electrical and mechanical specifications.

2. VLMS30K2L2-GS08 (Vishay Semiconductor Opto Division) - Parametric equivalent with red color matching. Lower forward voltage (1.8V) and reduced test current (2mA) with higher millicandela rating (14mcd).

3. HSMS-A100-J00J1 (Broadcom Limited) - MFR Recommended substitute with active product status. Red color with 2-PLCC package compatibility. Higher forward voltage (2.2V) and test current (20mA).

Parameter Comparison

Engineering Selection Recommendations

VLMH3102-GS08 is the primary substitute for direct replacement in applications where color indication is not critical to function. This part maintains identical electrical specifications (2V, 10mA) and mechanical dimensions while offering active product status and higher inventory availability (7800 pcs). The amber color represents a wavelength shift of 0.5nm from the original specification, acceptable for general indication purposes.

VLMS30K2L2-GS08 is suitable for applications requiring red color matching with reduced power consumption. The 1.8V forward voltage and 2mA test current provide lower operating power while maintaining comparable luminous intensity (14mcd). This configuration is appropriate for battery-powered or low-power indication circuits. Mechanical compatibility is identical to the main part.

HSMS-A100-J00J1 is the recommended substitute when sourcing from alternative manufacturers is required. This Broadcom component maintains red color specification and active product status. The 2-PLCC package is mechanically compatible with 2-SMD, J-Lead footprints in most PCB designs. Higher forward voltage (2.2V) and test current (20mA) require circuit design verification to ensure proper current-limiting resistor selection.

All three substitute parts maintain ROHS3 compliance and 2A MSL rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can VLMH3102-GS08 be used as a direct replacement for TLMH3102-GS08?

A: VLMH3102-GS08 is mechanically and electrically compatible with identical package dimensions, forward voltage, and test current specifications. The primary difference is color (amber vs. red). Direct substitution is possible in applications where color indication is not functionally critical.

Q: What are the key differences between VLMS30K2L2-GS08 and the original part?

A: VLMS30K2L2-GS08 maintains red color and identical package dimensions but operates at lower voltage (1.8V vs. 2V) and test current (2mA vs. 10mA). The millicandela rating is slightly higher (14mcd vs. 13.15mcd). Circuit design must account for the reduced forward voltage when selecting current-limiting resistors.

Q: Is HSMS-A100-J00J1 compatible with existing PCB layouts designed for TLMH3102-GS08?

A: HSMS-A100-J00J1 uses a 2-PLCC package compatible with 2-SMD, J-Lead footprints. Dimensional differences include 0.2mm additional length (3.20mm vs. 3.00mm) and 0.25mm additional height (2.10mm vs. 1.85mm). PCB layout verification is required to confirm clearance compatibility. The 2.20mm lens diameter is 0.2mm smaller than the original specification.

Q: Do all substitute parts meet the same compliance requirements?

A: All identified substitute parts are ROHS3 compliant with 2A MSL (4 Weeks) rating, matching the original part specifications. Compliance documentation is available from respective manufacturers.

Q: What is the impact of different forward voltages on circuit design?

A: Forward voltage differences (1.8V, 2V, 2.2V) directly affect current-limiting resistor calculations. Circuits designed for 2V operation require resistor value adjustment when substituting parts with different forward voltages. Verify that the selected resistor value maintains the desired luminous intensity within acceptable operating ranges.

Q: Are there inventory considerations when selecting a substitute?

A: VLMH3102-GS08 offers the highest inventory availability (7800 pcs), followed by HSMS-A100-J00J1 (20168 pcs) and VLMS30K2L2-GS08 (919 pcs). Inventory levels may influence long-term supply chain planning for production volumes.
