VLMP3101-GS18 Equivalent & Substitute Parts

Part Overview

The VLMP3101-GS18 is a green 560nm LED indication component in a 2-SMD, J-Lead package manufactured by Vishay Semiconductor Opto Division. This part is classified as obsolete, making identification of suitable substitutes necessary for ongoing design support and procurement. The component features a 2.1V forward voltage, 3.15mcd brightness rating, and 120° viewing angle in a compact 3.00mm × 2.80mm surface mount form factor. Obsolescence requires evaluation of active alternatives that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Color and Wavelength: Green indication function requires dominant wavelength in the green spectrum (527–560nm range)
• Forward Voltage (Vf): Must operate within the circuit's voltage supply constraints; 2.1V typical is the reference
• Brightness (Millicandela): Luminous intensity must meet or exceed application visibility requirements
• Viewing Angle: 120° viewing angle establishes the optical field requirement
• Mounting Type: Surface mount compatibility is mandatory for PCB assembly
• Package Footprint: Physical dimensions (3.00mm L × 2.80mm W, 1.85mm max height) determine PCB layout compatibility
• Compliance: RoHS3 and REACH status ensure regulatory alignment

The VLMP3100-GS08 (Vishay) qualifies as a direct substitute within the same manufacturer series with identical electrical and mechanical specifications but active product status. The 67-11/GHC-AT2V1/2T (Everlight) represents an alternative green LED with different package geometry and higher brightness, requiring design verification for mechanical fit and optical performance.

Parameter Comparison

Engineering Selection Recommendations

VLMP3100-GS08 is the primary substitute for VLMP3101-GS18. Both components are manufactured by Vishay within the VLM.3 series, share identical electrical specifications (2.1V Vf, 10mA test current, 120° viewing angle), and maintain the same 2-SMD J-Lead package footprint. The VLMP3100-GS08 is active in production with higher brightness (4mcd vs. 3.15mcd), providing improved luminous intensity. Both parts are ROHS3 compliant with identical moisture sensitivity ratings (2A, 4 Weeks). This substitution requires no design modification.

67-11/GHC-AT2V1/2T (Everlight) is an alternative green LED suitable only when mechanical constraints permit package variation. This part operates at 527nm dominant wavelength (shorter than the 560nm reference), features significantly higher brightness (630mcd), and uses a 1411 (3528 Metric) package with reduced height (0.80mm vs. 1.85mm). The different package geometry (4.60mm L vs. 3.00mm L) and wavelength shift require PCB layout verification and optical performance assessment. RoHS and moisture sensitivity compliance are not specified for this component.

Selection between VLMP3100-GS08 and 67-11/GHC-AT2V1/2T depends on PCB footprint constraints and brightness requirements. VLMP3100-GS08 is the direct replacement for existing designs. The Everlight alternative is applicable only when lower profile and higher brightness are design objectives and mechanical fit is confirmed.

Frequently Asked Questions (FAQ)

Q: Can VLMP3100-GS08 directly replace VLMP3101-GS18 without design changes?

A: Yes. Both components share identical electrical parameters (2.1V Vf, 10mA test current), optical specifications (560nm dominant wavelength, 120° viewing angle), and mechanical footprint (2-SMD J-Lead, 3.00 × 2.80mm, 1.85mm height). The VLMP3100-GS08 provides equal or superior performance with active product status.

Q: What are the key differences between VLMP3100-GS08 and 67-11/GHC-AT2V1/2T?

A: The primary differences are package type, brightness, and wavelength. VLMP3100-GS08 maintains the 2-SMD J-Lead package with 3.15mcd brightness at 560nm. The 67-11/GHC-AT2V1/2T uses a 1411 (3528 Metric) package with 630mcd brightness at 527nm and reduced height (0.80mm). Package geometry variation requires PCB layout verification.

Q: Is the 67-11/GHC-AT2V1/2T suitable for existing PCB designs?

A: The 67-11/GHC-AT2V1/2T has different package dimensions (4.60mm L vs. 3.00mm L) and height (0.80mm vs. 1.85mm). Mechanical compatibility must be verified against PCB footprint and assembly clearance requirements before implementation.

Q: What compliance certifications apply to these substitutes?

A: VLMP3101-GS18 and VLMP3100-GS08 are both ROHS3 compliant with 2A moisture sensitivity level (4 Weeks). The 67-11/GHC-AT2V1/2T compliance status is not specified in available documentation.

Q: Does wavelength difference between 560nm and 527nm affect visual appearance?

A: Yes. The 67-11/GHC-AT2V1/2T operates at 527nm (pure green), while VLMP3101-GS18 and VLMP3100-GS08 operate at 560nm (yellow-green). This wavelength shift produces a perceptibly different color appearance. Application requirements determine acceptability.

Q: Which substitute offers the best brightness performance?

A: The 67-11/GHC-AT2V1/2T provides the highest brightness at 630mcd, compared to 4mcd (VLMP3100-GS08) and 3.15mcd (VLMP3101-GS18). Selection depends on visibility requirements and whether the package change is mechanically feasible.
