VAOL-S2RP4 Equivalent & Substitute Parts

Part Overview

The VAOL-S2RP4 is a red 626nm LED indication component manufactured by Visual Communications Company (VCC) in a 2-SMD, J-Lead surface mount package. This discrete LED operates at 2.05V forward voltage with a 20mA test current and delivers 630mcd luminous intensity through a 120° viewing angle. The component is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for ongoing production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VAOL-S2RP4 is determined by strict alignment of the following parameters:

Critical Parameters (Must Match):

• Color: Red
• Package / Case: 2-SMD, J-Lead
• Supplier Device Package: 2-PLCC
• Mounting Type: Surface Mount
• Lens Style: Round with Flat Top
• Lens Size: 2.40mm Dia
• Viewing Angle: 120°
• Current - Test: 20mA

Compatible Parameter Ranges:

• Voltage - Forward (Vf): 2.0V to 2.05V
• Wavelength - Dominant: 624nm to 626nm
• Millicandela Rating: Acceptable within application-specific brightness requirements
• Physical Dimensions: Footprint compatibility within 3.10mm L x 2.70mm W tolerance
• Height (Max): Up to 2.10mm

All identified substitute parts meet these criteria and maintain electrical and mechanical interchangeability with the original VAOL-S2RP4 component.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 67-21/R6C-AP2R1B/2T (Everlight Electronics)

This component provides the closest electrical match to the VAOL-S2RP4, with identical forward voltage (2.05V) and wavelength (626nm). Active product status ensures long-term availability. ROHS3 compliance and 2-PLCC package configuration maintain full compatibility. Suitable for applications requiring precise voltage and wavelength specifications.

Secondary Substitute: 67-21SURC/S530-A7/TR8 (Everlight Electronics)

This part offers moderate brightness (215mcd) with forward voltage of 2V and wavelength of 624nm. Active status and high inventory availability (798 pcs) support production continuity. Appropriate for applications where brightness variation within the 55mcd to 215mcd range is acceptable.

Alternative Substitute: VLMR333U1AA-GS08 (Vishay Semiconductor Opto Division)

This component delivers the highest brightness rating (750mcd) with 2V forward voltage and 625nm wavelength. Active product status, ROHS3 compliance, and substantial inventory (6400 pcs) provide supply security. Reduced height (1.85mm) offers design flexibility for space-constrained applications. Suitable where increased luminous intensity is beneficial or required.

Substitute with Lower Brightness: 67-21SURC/S530-A2/TR8 (Everlight Electronics)

This part provides the lowest brightness option (55mcd) with 2V forward voltage and 624nm wavelength. Extensive inventory availability (24400 pcs) ensures supply continuity. Applicable to applications where reduced brightness is acceptable or preferred for power efficiency.

All substitute parts maintain the 2-SMD, J-Lead package configuration, 2.40mm lens diameter, 120° viewing angle, and 20mA test current of the original component.

Frequently Asked Questions (FAQ)

Q: Can the 67-21/R6C-AP2R1B/2T directly replace the VAOL-S2RP4 in existing designs?

A: Yes. The 67-21/R6C-AP2R1B/2T maintains identical forward voltage (2.05V), wavelength (626nm), and physical dimensions (3.10mm L x 2.70mm W, 2.10mm height). The 2-SMD, J-Lead package and 2-PLCC supplier device package are identical. No circuit modifications are required.

Q: What is the brightness difference between substitute options?

A: The VAOL-S2RP4 operates at 630mcd. The 67-21/R6C-AP2R1B/2T provides 99mcd, the 67-21SURC/S530-A7/TR8 provides 215mcd, and the VLMR333U1AA-GS08 provides 750mcd. Selection depends on application brightness requirements.

Q: Are all substitute parts RoHS3 compliant?

A: The 67-21/R6C-AP2R1B/2T and VLMR333U1AA-GS08 are explicitly ROHS3 compliant. RoHS status is not specified for the 67-21SURC/S530-A2/TR8 and 67-21SURC/S530-A7/TR8 variants.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: The VAOL-S2RP4 is supplied in Cut Tape (CT) and Digi-Reel® formats. All substitute parts are supplied in Tape & Reel (TR) format. Both packaging types are compatible with standard surface mount assembly equipment; TR format is standard for high-volume production.

Q: Does the VLMR333U1AA-GS08 fit the same PCB footprint?

A: The VLMR333U1AA-GS08 has dimensions of 3.00mm L x 2.80mm W with a maximum height of 1.85mm, compared to the VAOL-S2RP4 at 3.10mm L x 2.70mm W with 2.10mm height. The footprint is compatible; the reduced height provides additional design margin.

Q: What forward voltage range is acceptable for substitution?

A: The VAOL-S2RP4 operates at 2.05V. Substitute parts operate at 2.0V or 2.05V. This 50mV variation is within standard LED operating tolerances and does not require circuit redesign.

Q: Which substitute offers the best supply availability?

A: The 67-21SURC/S530-A2/TR8 has the highest inventory (24400 pcs), followed by the VLMR333U1AA-GS08 (6400 pcs). Both provide substantial supply security for production requirements.
