Key Parameters

Substitute Part Grouping Explanation

Substitution of the VLMD3101-GS08 is determined by strict equivalence across the following critical parameters:

• Package type: 2-SMD, J-Lead (2-PLCC supplier device package)
• Physical dimensions: 3.00mm L x 2.80mm W, 1.85mm max height
• Electrical characteristics: 1.8V forward voltage, 10mA test current
• Optical properties: Red color, 648nm dominant wavelength, 650nm peak wavelength
• Mechanical configuration: Round with Flat Top lens, 2.40mm diameter, 120° viewing angle
• Compliance: ROHS3 Compliant, REACH Unaffected

The VLMD3100-GS08 meets all mechanical and electrical compatibility requirements. The primary difference is the millicandela rating (11.2mcd vs. 32mcd), which represents a reduction in luminous intensity. This difference does not affect physical or electrical interchangeability but must be evaluated against application brightness requirements.

Parameter Comparison

Engineering Selection Recommendations

The VLMD3100-GS08 is the direct substitute for the obsolete VLMD3101-GS08. Both parts are manufactured by Vishay Semiconductor Opto Division within the VLM.3 series and share identical mechanical, electrical, and compliance specifications. The VLMD3100-GS08 maintains active product status with established supply availability (25,828 pcs in stock vs. 703 pcs for the obsolete part).

Selection between these parts is determined by luminous intensity requirements. The VLMD3100-GS08 operates at 11.2mcd, approximately 35% of the VLMD3101-GS08 rating of 32mcd. Applications requiring the higher brightness specification of the VLMD3101-GS08 must evaluate whether the reduced intensity of the VLMD3100-GS08 meets visibility requirements. Both parts maintain ROHS3 compliance and REACH unaffected status, supporting regulatory requirements for current manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can the VLMD3100-GS08 be used as a direct replacement for the VLMD3101-GS08?

A: The VLMD3100-GS08 is mechanically and electrically compatible with the VLMD3101-GS08. Both parts use identical 2-SMD, J-Lead packaging, share the same 3.00mm x 2.80mm x 1.85mm dimensions, and operate at 1.8V forward voltage. The primary consideration is the luminous intensity difference: the VLMD3100-GS08 provides 11.2mcd compared to the VLMD3101-GS08's 32mcd. Substitution is appropriate when application brightness requirements are satisfied by the lower intensity specification.

Q: What is the difference in millicandela rating between these parts?

A: The VLMD3101-GS08 is rated at 32mcd while the VLMD3100-GS08 is rated at 11.2mcd. This represents approximately 65% lower luminous intensity in the substitute part. The difference does not affect electrical interchangeability or physical fit; it only impacts perceived brightness in the application.

Q: Are both parts compliant with current regulatory standards?

A: Both the VLMD3101-GS08 and VLMD3100-GS08 are ROHS3 compliant and REACH unaffected. Both maintain MSL 2A (4 Weeks) moisture sensitivity classification. Regulatory compliance is equivalent between the two parts.

Q: What is the packaging difference between these parts?

A: The VLMD3101-GS08 is supplied in standard packaging, while the VLMD3100-GS08 is available in Tape & Reel (TR) format. Both use the same 2-PLCC supplier device package and 2-SMD, J-Lead case style. The packaging format difference does not affect component performance or compatibility.

Q: Why is the VLMD3101-GS08 listed as obsolete?

A: The VLMD3101-GS08 has been discontinued by the manufacturer. The VLMD3100-GS08 remains in active production and is the recommended substitute for new designs and ongoing procurement requirements.
