Substitute Part Grouping Explanation

Substitution of the VLMH3101-GS08 is determined by strict equivalence across the following critical parameters:

• Color and Wavelength: Amber specification at 618.5nm dominant wavelength and 635nm peak wavelength
• Electrical Characteristics: 2V forward voltage and 10mA test current
• Optical Properties: 120° viewing angle with clear lens transparency
• Mechanical Compatibility: 2-SMD, J-Lead package with 2.40mm diameter round lens and flat top design
• Physical Dimensions: 3.00mm L x 2.80mm W footprint with 1.85mm maximum height
• Compliance: ROHS3 compliance and 2A MSL rating

The VLMH3100-GS08 meets all these criteria while maintaining active product status within the same VLM.3 series from Vishay Semiconductor Opto Division.

Parameter Comparison

Engineering Selection Recommendations

Both components are manufactured by Vishay Semiconductor Opto Division within the VLM.3 series and maintain identical electrical, optical, and mechanical specifications. The VLMH3100-GS08 carries active product status, ensuring ongoing availability and supply chain support. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, confirming regulatory and environmental equivalence. The VLMH3100-GS08 provides a brightness increase of 2.15mcd (10mcd versus 7.85mcd), which represents enhanced optical performance while maintaining all other functional parameters. This substitution is suitable for direct replacement in existing designs without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the VLMH3100-GS08 be used as a direct replacement for the VLMH3101-GS08?

A: Yes. Both components share identical electrical characteristics (2V forward voltage, 10mA test current), optical properties (618.5nm dominant wavelength, 120° viewing angle), mechanical dimensions (3.00mm L x 2.80mm W, 1.85mm height), and package configuration (2-SMD, J-Lead). The VLMH3100-GS08 provides increased brightness at 10mcd compared to 7.85mcd, with no circuit modifications required.

Q: What is the primary difference between these two parts?

A: The VLMH3101-GS08 is obsolete, while the VLMH3100-GS08 maintains active product status. The VLMH3100-GS08 also provides higher luminous intensity (10mcd versus 7.85mcd). All other specifications remain equivalent.

Q: Are the packaging options compatible?

A: The VLMH3101-GS08 is supplied in standard packaging, while the VLMH3100-GS08 is available in Tape & Reel (TR) format. Both use the identical 2-SMD, J-Lead package configuration with matching physical dimensions and mounting characteristics, ensuring PCB-level compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the VLMH3101-GS08 and VLMH3100-GS08 are ROHS3 compliant with identical Moisture Sensitivity Level ratings of 2A (4 Weeks), confirming equivalent regulatory and environmental compliance.

Q: Is the increased brightness of the VLMH3100-GS08 a concern for existing designs?

A: The brightness increase from 7.85mcd to 10mcd represents enhanced optical performance. For applications where brightness is not a limiting factor, this increase presents no compatibility issues. For brightness-sensitive applications, series resistor adjustment may be implemented to match the original optical output if required.
