Key Parameters

Substitute Part Grouping Explanation

The VLMK334BACB-GS18 has one identified parametric equivalent: VLMK334BACB-GS08. Substitution between these parts is valid based on the following criteria:

Matching Electrical Parameters:

• Identical wavelength specifications (616nm dominant, 622nm peak)
• Identical luminous intensity (2800mcd)
• Identical forward voltage (2.25V typical)
• Identical test current (50mA)
• Identical viewing angle (120°)

Matching Mechanical Parameters:

• Identical package type (2-SMD, J-Lead)
• Identical lens configuration (Round with Flat Top, 2.40mm diameter)
• Identical physical dimensions (3.00mm L x 2.80mm W, 1.85mm max height)
• Identical mounting type (Surface Mount)

Matching Compliance & Environmental:

• Identical RoHS status (ROHS3 Compliant)
• Identical MSL rating (2A, 4 Weeks)
• Identical REACH status (REACH Unaffected)

The primary difference between these parts is packaging format and product status, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The VLMK334BACB-GS08 is the direct parametric equivalent for the obsolete VLMK334BACB-GS18. All electrical, mechanical, and optical specifications are identical. The VLMK334BACB-GS08 maintains active product status with ROHS3 compliance and identical MSL rating, ensuring continued availability and regulatory compliance for new designs and production continuity.

The only distinction is packaging format: VLMK334BACB-GS18 is supplied in standard packaging, while VLMK334BACB-GS08 is supplied in Tape & Reel format. This difference does not affect component performance or PCB assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can VLMK334BACB-GS08 be used as a direct replacement for VLMK334BACB-GS18?

A: Yes. All electrical parameters (forward voltage, test current, wavelength), optical parameters (luminous intensity, viewing angle), mechanical dimensions, and compliance certifications are identical. The parts are functionally interchangeable.

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

A: The primary difference is packaging format. VLMK334BACB-GS18 uses standard packaging, while VLMK334BACB-GS08 uses Tape & Reel format. This affects order quantity and handling but not component performance or assembly compatibility.

Q: Why is VLMK334BACB-GS18 listed as obsolete?

A: The VLMK334BACB-GS18 has been discontinued by the manufacturer. VLMK334BACB-GS08 remains in active production and is the recommended source for this LED specification.

Q: Are there any compliance or environmental differences?

A: No. Both parts carry identical ROHS3 compliance, REACH unaffected status, and MSL 2A (4 Weeks) ratings.

Q: Will this substitute work in existing PCB designs without modification?

A: Yes. Identical package type (2-SMD, J-Lead), physical dimensions (3.00mm L x 2.80mm W x 1.85mm max height), and mounting type (Surface Mount) ensure direct PCB compatibility without layout changes.
