VAOL-10GRE4 Equivalent & Substitute Parts

Part Overview

The VAOL-10GRE4 is a red LED indication component manufactured by Visual Communications Company (VCC). This through-hole radial LED features a 10mm clear domed lens and operates at 2V forward voltage with a 2500mcd brightness rating at 20mA test current. The dominant wavelength is 623nm with a peak wavelength of 630nm.

This part is classified as obsolete. Locating equivalent substitute components is necessary to maintain design continuity and ensure component availability for production and repair applications. Active alternative parts meeting the same electrical and mechanical specifications are available from other manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the VAOL-10GRE4 is determined by the following critical parameters that must remain compatible:

Mechanical Compatibility:

• Lens size: 10.00mm diameter
• Lens style: Round with domed top
• Mounting type: Through hole radial configuration
• Physical height: Maximum 13.50mm acceptable

Electrical Compatibility:

• Forward voltage: 2V to 2.1V range
• Test current: 20mA
• Color: Red
• Lens transparency: Clear (colorless)

Regulatory Compliance:

• RoHS3 compliance required
• REACH unaffected status

The WP813SRC/J4 manufactured by Kingbright meets all substitution criteria. This part maintains identical mechanical form factor, compatible electrical characteristics within acceptable tolerances, and equivalent regulatory compliance status.

Engineering Selection Recommendations

Primary Substitute: WP813SRC/J4 (Kingbright)

The WP813SRC/J4 is the qualified substitute for the obsolete VAOL-10GRE4. Selection is based on the following engineering factors:

Compliance Status: Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for current production environments.

Product Availability: The WP813SRC/J4 is classified as active product with 13,955 units in stock, ensuring reliable supply chain continuity compared to the obsolete VAOL-10GRE4.

Electrical Compatibility: Forward voltage tolerance of 2.1V versus 2V represents a 5% increase within acceptable operating margins for standard LED indication circuits. Both parts operate at identical 20mA test current.

Mechanical Compatibility: Identical 10mm lens diameter, round domed top configuration, and through-hole radial mounting ensure direct PCB footprint compatibility. Maximum height of 13.50mm accommodates the original 13.00mm specification.

Optical Performance: The WP813SRC/J4 delivers 3000mcd brightness compared to 2500mcd, providing enhanced visibility. Wavelength shift from 623nm dominant to 640nm remains within the red spectrum range and maintains visual color consistency for indication applications.

Moisture Handling: The substitute part features MSL 1 (unlimited) versus MSL 2 (1 year), offering superior moisture resistance for extended storage and field deployment.

Frequently Asked Questions (FAQ)

Q: Can the WP813SRC/J4 be used as a direct replacement for VAOL-10GRE4 in existing PCB designs?

A: Yes. Both parts share identical 10mm lens diameter, round domed top lens style, through-hole radial mounting configuration, and 13mm maximum height envelope. No PCB layout modifications are required.

Q: What is the significance of the 0.1V forward voltage difference between the two parts?

A: The VAOL-10GRE4 operates at 2V typical forward voltage while the WP813SRC/J4 operates at 2.1V typical. This 5% difference is within standard LED tolerance ranges and does not require circuit redesign for typical indication applications using current-limiting resistors.

Q: Why does the WP813SRC/J4 have a higher millicandela rating?

A: The WP813SRC/J4 produces 3000mcd compared to 2500mcd for the VAOL-10GRE4. This increased brightness is a performance enhancement that maintains backward compatibility while providing improved visibility for indication purposes.

Q: Are there wavelength differences between these parts?

A: The VAOL-10GRE4 has a dominant wavelength of 623nm (peak 630nm) while the WP813SRC/J4 has a dominant wavelength of 640nm (peak 660nm). Both wavelengths are within the red spectrum and produce visually identical red color for indication applications.

Q: What is the difference in moisture sensitivity levels?

A: The VAOL-10GRE4 is rated MSL 2 (1 year maximum floor life) while the WP813SRC/J4 is rated MSL 1 (unlimited floor life). The substitute part offers superior moisture resistance, reducing risk during storage and handling.

Q: Does the WP813SRC/J4 meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing and use.

Q: What is the viewing angle specification for the substitute part?

A: The WP813SRC/J4 specifies a 15° viewing angle. This parameter was not provided for the VAOL-10GRE4 in the original specifications.

Q: Is the WP813SRC/J4 currently available for procurement?

A: Yes. The WP813SRC/J4 is classified as active product with 13,955 units in stock, ensuring immediate availability compared to the obsolete VAOL-10GRE4.
