VLWR9932 Equivalent & Substitute Parts

Part Overview

The VLWR9932 is a red LED indication component manufactured by Vishay Semiconductor Opto Division, part of the TELUX™ series. This through-hole mounted discrete LED operates at 2.2V forward voltage with a dominant wavelength of 615nm and provides 0.7mcd luminous intensity. The component is actively produced and ROHS3 compliant, making it suitable for standard indication applications requiring red light output in 4-DIP packaging format.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across critical parameters including forward voltage, test current, wavelength specifications, package configuration, and mounting characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VLWR9932 are identified based on strict equivalence across the following critical parameters:

• Electrical Characteristics: Forward voltage (Vf) of 2.2V and test current of 70mA
• Optical Specifications: Red color, dominant wavelength of 615nm, peak wavelength of 624nm, and 0.7mcd luminous intensity
• Mechanical Compatibility: 4-DIP (0.200", 5.08mm) package configuration with through-hole mounting
• Physical Dimensions: 7.62mm L x 7.62mm W footprint and 6.41mm maximum height
• Lens Configuration: Round with domed top lens, clear transparency
• Compliance & Status: ROHS3 compliance, REACH unaffected status, and active product status

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both the VLWR9932 and VLWR9930 are active products from Vishay Semiconductor Opto Division with identical electrical, optical, and mechanical specifications. Both components maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and use.

Selection between these parts may be based on inventory availability and supply chain considerations. The VLWR9930 currently maintains higher inventory levels (2810 pcs) compared to the VLWR9932 (739 pcs), which may influence procurement decisions for high-volume applications or extended lead-time mitigation strategies.

Frequently Asked Questions (FAQ)

Q: Can VLWR9930 be used as a direct replacement for VLWR9932?

A: Yes. Both components share identical electrical characteristics (2.2V forward voltage, 70mA test current), optical specifications (615nm dominant wavelength, 0.7mcd intensity), mechanical configuration (4-DIP through-hole package), and physical dimensions (7.62mm x 7.62mm x 6.41mm max height). They are parametric equivalents.

Q: Are there any differences in compliance or regulatory status between these parts?

A: No. Both VLWR9932 and VLWR9930 are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: What determines substitutability for red LED indication components in 4-DIP packages?

A: Substitutability is determined by equivalence in forward voltage, test current, dominant and peak wavelengths, luminous intensity, viewing angle, package configuration, mounting type, lens style and transparency, physical dimensions, and compliance certifications.

Q: Can these components be used interchangeably in PCB designs?

A: Yes. Identical package dimensions (4-DIP 0.200" pitch), mounting type (through-hole), and physical footprint (7.62mm x 7.62mm) ensure mechanical and electrical interchangeability in PCB layouts designed for either part number.

Q: What is the significance of the 90° viewing angle specification?

A: The 90° viewing angle indicates the half-angle at which luminous intensity remains at 50% of the peak value, defining the light distribution pattern for indication applications.
