VLMR334BACB-GS18 Equivalent & Substitute Parts

Part Overview

The VLMR334BACB-GS18 is a red 625nm LED indication component manufactured by Vishay Semiconductor Opto Division in a 2-SMD, J-Lead surface mount package. This part is classified as obsolete, which necessitates identification of active equivalent alternatives for ongoing production and procurement requirements. The component delivers 2200mcd luminous intensity at 50mA test current with a 2.2V typical forward voltage and 120° viewing angle, making it suitable for standard LED indication applications in compact form factors.

Substitute Part Grouping Explanation

The VLMR334BACB-GS18 has one parametric equivalent identified within the VLMR334 series: VLMR334BACB-GS08. Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Wavelength - Dominant: 625nm
• Wavelength - Peak: 632nm
• Millicandela Rating: 2200mcd
• Voltage - Forward (Vf) Typical: 2.2V
• Current - Test: 50mA
• Viewing Angle: 120°
• Lens Style: Round with Flat Top
• Lens Size: 2.40mm Dia
• Package / Case: 2-SMD, J-Lead
• Physical Dimensions: 3.00mm L x 2.80mm W x 1.85mm H (Max)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 2A (4 Weeks)

The substitute part differs only in product status (Active vs. Obsolete) and packaging format (Cut Tape & Digi-Reel vs. standard packaging), with no electrical or mechanical parameter variations.

Parameter Comparison

Engineering Selection Recommendations

The VLMR334BACB-GS08 is the direct parametric equivalent for the obsolete VLMR334BACB-GS18. Both components maintain identical electrical characteristics, optical properties, mechanical dimensions, and regulatory compliance status. The substitute part carries Active product status with significantly higher inventory availability (11,314 pcs vs. 657 pcs), ensuring supply chain continuity. Both parts satisfy ROHS3 compliance and REACH unaffected requirements. The packaging format difference (Cut Tape & Digi-Reel for the substitute) represents a standard industry distribution variation with no impact on component functionality or PCB assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Are the VLMR334BACB-GS18 and VLMR334BACB-GS08 electrically identical?

A: Yes. Both components share identical forward voltage (2.2V typical), test current (50mA), luminous intensity (2200mcd), and wavelength specifications (625nm dominant, 632nm peak).

Q: Will the VLMR334BACB-GS08 fit the same PCB footprint as the VLMR334BACB-GS18?

A: Yes. Both parts use the 2-SMD, J-Lead package with identical dimensions (3.00mm L x 2.80mm W x 1.85mm H max) and surface mount mounting type.

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

A: The primary difference is product status: VLMR334BACB-GS18 is obsolete, while VLMR334BACB-GS08 is active. The substitute also uses Cut Tape & Digi-Reel packaging format. All electrical, optical, and mechanical parameters are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both VLMR334BACB-GS18 and VLMR334BACB-GS08 are ROHS3 compliant and REACH unaffected.

Q: What is the moisture sensitivity level for these components?

A: Both parts carry MSL 2A (4 Weeks) rating, requiring storage in controlled humidity conditions and baking before reflow soldering if moisture absorption limits are exceeded.
