VLMB41P2Q2-GS18 Equivalent & Substitute Parts

Part Overview

The VLMB41P2Q2-GS18 is a blue 469nm LED indication component manufactured by Vishay Semiconductor Opto Division. This discrete 3.2V surface mount LED features a 2-SMD J-Lead package configuration with a round flat-top lens design. The part is currently classified as obsolete, which necessitates identification of active equivalent alternatives to maintain design continuity and ensure supply chain availability for new production runs and field replacements.

Substitute Part Grouping Explanation

Substitution of the VLMB41P2Q2-GS18 is determined by strict equivalence across the following critical parameters:

• Wavelength specification (dominant 469nm, peak 464nm)
• Forward voltage rating (3.2V typical)
• Optical output (84mcd at 10mA test current)
• Viewing angle (120°)
• Physical package dimensions (3.00mm L x 2.80mm W, 1.85mm max height)
• Package type (2-SMD, J-Lead / 2-PLCC)
• Lens configuration (round with flat top, 2.40mm diameter)
• Compliance certifications (ROHS3, REACH Unaffected)

The VLMB41P2Q2-GS08 meets all these criteria and represents a direct parametric equivalent. The primary distinction is packaging format: the substitute is supplied in Tape & Reel (TR) configuration versus the main part's standard packaging, and the substitute maintains active product status.

Parameter Comparison

Engineering Selection Recommendations

The VLMB41P2Q2-GS08 is the direct substitute for the obsolete VLMB41P2Q2-GS18. Both components are manufactured by Vishay Semiconductor Opto Division within the VLM.4 series and maintain identical electrical and optical specifications. The substitute part carries active product status, ensuring ongoing availability and supply chain support.

Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The MSL rating of 2A (4 Weeks) applies to both components, requiring equivalent moisture control during storage and handling.

The primary consideration for component selection is packaging format. The substitute is supplied in Tape & Reel (TR) configuration, which is standard for high-volume production environments. If the original standard packaging format is required for specific assembly processes, this distinction must be evaluated against supply availability and lead time constraints.

Frequently Asked Questions (FAQ)

Q: Can VLMB41P2Q2-GS08 be used as a direct replacement for VLMB41P2Q2-GS18 in existing designs?

A: Yes. Both parts are parametrically identical across all electrical, optical, and mechanical specifications. The substitute maintains the same forward voltage (3.2V), optical output (84mcd), wavelength (469nm dominant), viewing angle (120°), and physical dimensions (3.00mm L x 2.80mm W, 1.85mm height). PCB layout and circuit design require no modification.

Q: What is the difference between the two part numbers?

A: The primary difference is packaging format. VLMB41P2Q2-GS18 uses standard packaging, while VLMB41P2Q2-GS08 is supplied in Tape & Reel (TR) format. The suffix designations (-GS18 versus -GS08) indicate this packaging distinction. All component specifications remain identical.

Q: Why is the original part marked as obsolete?

A: The VLMB41P2Q2-GS18 has been transitioned to obsolete status by the manufacturer. The VLMB41P2Q2-GS08 represents the active equivalent and is the recommended part for new designs and ongoing production.

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

A: No. Both parts carry identical ROHS3 compliance and REACH unaffected status. Moisture sensitivity level (MSL 2A, 4 Weeks) is the same for both components.

Q: Does the Tape & Reel packaging affect component performance?

A: No. Tape & Reel packaging is a delivery and handling format only. It does not affect electrical performance, optical characteristics, or reliability of the LED component itself.

Q: What is the inventory status of the substitute part?

A: VLMB41P2Q2-GS08 maintains active product status with 9419 pieces in stock, ensuring reliable supply availability compared to the obsolete main part (739 pieces remaining).
