Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VLMP31H2J2-GS18 are classified based on the following substitution criteria:

Parametric Equivalent: Parts that maintain identical or functionally equivalent electrical and mechanical specifications within the same package family.

MFR Recommended Substitutes: Parts from alternative manufacturers that provide functional equivalence with allowable parameter variations for the intended application.

The primary substitution parameters are:

• Color: Green
• Mounting Type: Surface Mount
• Lens Size: 2.40mm Dia
• Viewing Angle: 120°
• Forward Voltage (Vf): 2.1V nominal
• Package compatibility: 2-SMD, J-Lead or equivalent footprint

Parameter Comparison

Engineering Selection Recommendations

VLMP31H2J2-GS08 (Parametric Equivalent): This Vishay part is the direct parametric equivalent with identical electrical specifications (2.1V, 10mA, 5mcd, 560nm) and mechanical dimensions. It maintains the same 2-SMD, J-Lead package and is currently in active production status. This part is ROHS3 compliant and recommended as the primary replacement for the obsolete VLMP31H2J2-GS18.

67-21VGC/TR8 (MFR Recommended Substitute): This Everlight part maintains the same forward voltage (2.1V) and viewing angle (120°) as the original. It differs in package type (1411 vs 2-SMD, J-Lead), lens transparency (diffused vs clear), and brightness rating (25mcd vs 5mcd). This substitute is suitable for applications where package footprint compatibility is not critical and diffused lens characteristics are acceptable.

67-21SUGC/S400-A4/TR8 (MFR Recommended Substitute): This Everlight part features a higher forward voltage (3.3V vs 2.1V), increased test current (20mA vs 10mA), and significantly higher brightness (279mcd vs 5mcd). The wavelength differs at 525nm. This substitute requires circuit redesign to accommodate the higher voltage and current specifications and is suitable only for applications requiring increased brightness output.

Frequently Asked Questions (FAQ)

Q: Can VLMP31H2J2-GS08 be used as a direct replacement for VLMP31H2J2-GS18?

A: Yes. VLMP31H2J2-GS08 is a parametric equivalent with identical electrical and mechanical specifications. Both parts share the same forward voltage (2.1V), test current (10mA), brightness rating (5mcd), wavelength (560nm), package type (2-SMD, J-Lead), and physical dimensions. The primary difference is packaging format (bulk vs tape & reel) and product status (active vs obsolete).

Q: What are the key differences between the Vishay and Everlight substitutes?

A: The Everlight 67-21VGC/TR8 maintains voltage and viewing angle compatibility but uses a different package (1411 vs 2-SMD, J-Lead) and diffused lens instead of clear. The Everlight 67-21SUGC/S400-A4/TR8 requires higher voltage (3.3V) and current (20mA) operation with significantly higher brightness output (279mcd). Both Everlight parts have different wavelength specifications.

Q: Will the Everlight 67-21SUGC/S400-A4/TR8 work in existing circuits designed for the VLMP31H2J2-GS18?

A: No. This part requires circuit modification. The 3.3V forward voltage and 20mA test current differ from the original 2.1V and 10mA specifications. Direct substitution without circuit redesign will result in improper LED operation or component failure.

Q: Are all substitute parts ROHS3 compliant?

A: VLMP31H2J2-GS08 is confirmed ROHS3 compliant. RoHS compliance status is not specified for the Everlight parts (67-21VGC/TR8 and 67-21SUGC/S400-A4/TR8) in the provided documentation.

Q: What is the impact of lens transparency differences between clear and diffused options?

A: Clear lens (VLMP31H2J2-GS18, VLMP31H2J2-GS08, 67-21SUGC/S400-A4/TR8) provides direct light transmission with defined brightness concentration. Diffused lens (67-21VGC/TR8) scatters light over a wider area, reducing peak brightness but improving visibility from off-axis angles. Selection depends on application requirements for brightness concentration versus angular light distribution.

Q: Can package dimensions vary between substitutes?

A: Yes. VLMP31H2J2-GS08 maintains identical dimensions (3.00mm L x 2.80mm W x 1.85mm H). The Everlight 67-21SUGC/S400-A4/TR8 is slightly larger (3.10mm L x 2.70mm W x 2.10mm H). The Everlight 67-21VGC/TR8 uses a different package with larger length (4.60mm) and reduced height (0.85mm). PCB layout compatibility must be verified before substitution.
