Key Parameters

Substitute Part Grouping Explanation

Substitution of the VLMP31G2J1-GS08 is determined by strict equivalence across the following critical parameters:

• Color and wavelength characteristics (Green, 560nm dominant wavelength)
• Electrical performance (2.1V forward voltage, 10mA test current, 4mcd luminous intensity)
• Optical properties (120° viewing angle, Round with Flat Top lens, 2.40mm lens diameter)
• Mechanical compatibility (2-SMD J-Lead package, 3.00mm L x 2.80mm W dimensions, 1.85mm maximum height)
• Compliance and environmental ratings (ROHS3 compliant, 2A MSL)

The VLMP3100-GS08 meets all these criteria and is classified as a parametric equivalent within the VLM.3 series from Vishay Semiconductor Opto Division.

Parameter Comparison

Engineering Selection Recommendations

Both the VLMP31G2J1-GS08 and VLMP3100-GS08 are Active status components from Vishay Semiconductor Opto Division within the VLM.3 series. Selection between these parts is based on availability and inventory requirements rather than technical differentiation. Both parts maintain ROHS3 compliance, REACH unaffected status, and identical electrical and mechanical specifications. The VLMP3100-GS08 currently has higher inventory availability (1000 Pcs) compared to the VLMP31G2J1-GS08 (816 Pcs). Peak wavelength variation (565nm versus 555nm) falls within acceptable tolerance for green LED indication applications and does not affect functional compatibility in standard circuit designs.

Frequently Asked Questions (FAQ)

Q: Can VLMP3100-GS08 be used as a direct replacement for VLMP31G2J1-GS08?

A: Yes. Both parts are parametric equivalents with identical forward voltage (2.1V), test current (10mA), luminous intensity (4mcd), viewing angle (120°), and package specifications (2-SMD, J-Lead, 3.00mm L x 2.80mm W, 1.85mm height). Peak wavelength differs by 10nm (565nm vs 555nm), which is within acceptable tolerance for green indication LEDs.

Q: Are there any compliance or environmental differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings (2A, 4 Weeks). Export classification (EAR99) and tariff codes (8541.41.0000) are identical.

Q: What is the primary reason to consider substitution?

A: Inventory availability. The VLMP3100-GS08 has higher stock levels (1000 Pcs) versus the VLMP31G2J1-GS08 (816 Pcs), making it suitable for high-volume production requirements without technical compromise.

Q: Are the mechanical dimensions identical?

A: Yes. Both parts share identical dimensions (3.00mm L x 2.80mm W, 1.85mm maximum height) and use the same 2-PLCC package format, ensuring PCB layout compatibility without redesign.

Q: Do these parts have different optical characteristics?

A: Both parts deliver 4mcd luminous intensity with 120° viewing angle and identical lens geometry (Round with Flat Top, 2.40mm diameter). The 10nm peak wavelength difference (565nm vs 555nm) does not affect visual appearance or functional performance in indication circuits.
