Substitute Part Grouping Explanation

Substitute parts for the VLMP3100-GS18 are grouped into two categories based on substitution compatibility:

Parametric Equivalents (Direct Substitutes): Parts that maintain identical or functionally equivalent electrical and mechanical parameters within the same package family. These parts share the same 2-SMD, J-Lead package configuration, 2.1V forward voltage, 10mA test current, 120° viewing angle, and identical physical dimensions (3.00mm × 2.80mm × 1.85mm max height). Parametric equivalents include VLMP3100-GS08 and VLMP31G2J1-GS08, both from Vishay Semiconductor Opto Division's VLM.3 series.

Manufacturer Recommended Substitute: The 67-11/GHC-AT2V1/2T from Everlight Electronics Co Ltd is classified as a manufacturer-recommended alternative. This part differs in package type (1411/3528 Metric vs. 2-SMD, J-Lead), physical dimensions (4.60mm × 2.80mm × 0.80mm max height), wavelength characteristics (527nm dominant vs. 560nm), and brightness rating (630mcd vs. 4mcd). Selection of this substitute requires design-level evaluation due to these parameter differences.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (Same Package, Electrical Characteristics): VLMP3100-GS08 and VLMP31G2J1-GS08 are suitable direct replacements for the obsolete VLMP3100-GS18. Both parts maintain active product status with Vishay Semiconductor Opto Division, ensuring long-term availability and supply chain stability. Both are ROHS3 compliant with identical MSL ratings (2A, 4 Weeks). VLMP3100-GS08 provides identical wavelength characteristics (560nm dominant, 555nm peak), while VLMP31G2J1-GS08 exhibits a slight wavelength shift (565nm dominant, 565nm peak) within the green spectrum. Both maintain the same 2.1V forward voltage, 10mA test current, 4mcd brightness, and identical physical footprint (3.00mm × 2.80mm × 1.85mm max height). Selection between these two depends on wavelength tolerance requirements in the application.

For Alternative Substitution (Different Package, Modified Characteristics): The 67-11/GHC-AT2V1/2T from Everlight Electronics Co Ltd is a manufacturer-recommended alternative suitable only when design constraints permit package and performance modifications. This part uses a different package type (1411/3528 Metric), resulting in a lower profile (0.80mm max height vs. 1.85mm) and slightly larger footprint (4.60mm length vs. 3.00mm). The part exhibits significantly different optical characteristics: 527nm dominant wavelength (vs. 560nm), 630mcd brightness (vs. 4mcd), and unspecified forward voltage and test current. This substitute is appropriate for space-constrained applications requiring lower profile components or higher brightness output, provided circuit design accommodates the unspecified electrical parameters through empirical validation.

Frequently Asked Questions (FAQ)

Q: Can VLMP3100-GS08 be used as a direct replacement for VLMP3100-GS18?

A: Yes. VLMP3100-GS08 is a parametric equivalent with identical electrical specifications (2.1V forward voltage, 10mA test current), optical characteristics (560nm dominant wavelength, 4mcd brightness), mechanical dimensions (3.00mm × 2.80mm × 1.85mm), and package configuration (2-SMD, J-Lead). The primary difference is packaging format: VLMP3100-GS18 is supplied in bulk, while VLMP3100-GS08 is supplied in Tape & Reel format. Both are ROHS3 compliant with 2A MSL rating.

Q: What is the difference between VLMP3100-GS08 and VLMP31G2J1-GS08?

A: Both parts are parametric equivalents with identical electrical specifications, package configuration, and physical dimensions. The difference is wavelength: VLMP3100-GS08 has 560nm dominant wavelength (555nm peak), while VLMP31G2J1-GS08 has 565nm dominant wavelength (565nm peak). Both remain within the green spectrum. Selection depends on application wavelength tolerance requirements.

Q: Is the 67-11/GHC-AT2V1/2T a direct replacement?

A: No. The 67-11/GHC-AT2V1/2T is a manufacturer-recommended alternative, not a direct replacement. It uses a different package type (1411/3528 Metric vs. 2-SMD, J-Lead), has different physical dimensions (4.60mm × 2.80mm × 0.80mm vs. 3.00mm × 2.80mm × 1.85mm), and different optical characteristics (527nm wavelength, 630mcd brightness vs. 560nm, 4mcd). This substitute requires design-level evaluation and is suitable only when package and performance modifications are acceptable.

Q: What are the key parameters that determine substitution compatibility?

A: For the VLMP3100-GS18, substitution compatibility is determined by: color (green), package type (2-SMD, J-Lead), forward voltage (2.1V), test current (10mA), viewing angle (120°), lens style (round with flat top), lens size (2.40mm diameter), mounting type (surface mount), and physical dimensions (3.00mm × 2.80mm × 1.85mm max height). Wavelength characteristics (dominant and peak) and brightness rating (millicandela) may vary within acceptable application tolerances.

Q: Are all substitute parts ROHS3 compliant?

A: VLMP3100-GS08 and VLMP31G2J1-GS08 are confirmed ROHS3 compliant with 2A MSL rating. The 67-11/GHC-AT2V1/2T compliance status is not specified in available documentation.

Q: What is the difference in packaging between the main part and substitutes?

A: VLMP3100-GS18 is supplied in bulk packaging. VLMP3100-GS08 and VLMP31G2J1-GS08 are supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly. The 67-11/GHC-AT2V1/2T is also supplied in Tape & Reel format. Tape & Reel packaging is compatible with automated pick-and-place assembly equipment.
