3PGC-201-S

Part Overview

The 3PGC-201-S is a through-hole green LED indicator manufactured by Bivar Inc., designed for discrete 2.2V radial applications in visual indication circuits. This product is currently obsolete, making identification of suitable substitutes essential for ongoing maintenance, repair, and legacy system support. The 3mm T-1 package format with clear lens and 20mcd brightness rating provides standard green indication across industrial and consumer applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3PGC-201-S is determined by strict alignment across the following electrical and mechanical parameters:

Electrical Compatibility Parameters:

• Color: Green
• Lens Transparency: Clear
• Mounting Type: Through Hole
• Current - Test: 20mA
• Viewing Angle: 20°
• Package / Case: Radial

Mechanical Compatibility Parameters:

• Lens Size: 3mm, T-1
• Lens Style: Round with Domed Top
• Height compatibility within PCB layout constraints

Allowable Variation Parameters:

• Forward Voltage (Vf): Substitutes with Vf between 2.1V and 2.2V remain compatible within standard circuit protection schemes
• Millicandela Rating: Substitutes with higher brightness (40mcd vs 20mcd) provide enhanced visibility without circuit modification
• Wavelength - Peak: Substitutes within the green spectrum range (555nm to 568nm) maintain consistent color perception

The 3GC-201-S meets all substitution criteria while offering improved brightness and active product status.

Engineering Selection Recommendations

The 3GC-201-S is qualified as a direct substitute for the obsolete 3PGC-201-S based on the following factors:

Product Status Advantage: The 3GC-201-S maintains active product status with current manufacturing support, ensuring supply chain continuity for replacement and new production requirements.

Compliance Alignment: Both parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. The 3GC-201-S additionally carries RoHS3 compliance certification, meeting modern environmental and regulatory standards.

Electrical Compatibility: The forward voltage difference (2.1V vs 2.2V) of 0.1V is within acceptable tolerance for standard current-limiting circuits. The 20mA test current remains identical, confirming driver compatibility without circuit redesign.

Mechanical Compatibility: Both parts employ the T-1 3mm radial package with identical mounting type and viewing angle. The height increase from 5.10mm to 6.58mm requires verification against specific PCB layout constraints but does not compromise electrical function.

Brightness Enhancement: The increased millicandela rating (40mcd vs 20mcd) provides superior visibility without adverse circuit effects, particularly beneficial in applications subject to ambient light variations.

Frequently Asked Questions (FAQ)

Q: Can the 3GC-201-S replace the 3PGC-201-S in existing designs without circuit modification? A: Yes. The electrical parameters—forward voltage, test current, and viewing angle—are compatible. The circuit protection scheme remains unchanged. Height verification against PCB clearance specifications is required prior to implementation.

Q: What is the practical impact of the 0.1V forward voltage difference? A: The 0.1V difference (2.1V vs 2.2V) is negligible in standard LED driver circuits with current-limiting resistors. This variation falls within normal component tolerance ranges and does not require circuit adjustment.

Q: Does the increased brightness (40mcd vs 20mcd) affect circuit operation? A: No. Brightness is determined by LED construction and does not impact electrical characteristics. Higher brightness is an operational improvement that provides enhanced visibility under identical circuit conditions.

Q: Why does the substitute part have greater maximum height (6.58mm vs 5.10mm)? A: Physical dimension changes reflect manufacturing tolerances and design evolution within the T-1 3mm package family. PCB layout clearance must be confirmed, but this does not affect electrical function.

Q: What compliance certifications apply to the substitute part? A: The 3GC-201-S carries RoHS3 compliance certification in addition to shared ECCN and HTSUS classifications. This provides enhanced environmental and regulatory alignment with current standards.

Q: Is the higher brightness substitute suitable for applications requiring the original brightness level? A: Yes. The substitute's 40mcd brightness exceeds the original 20mcd specification. Applications sensitive to specific brightness levels should assess the visibility impact, but functional compatibility is assured.
