LED GREEN/RED DIFFUSED T/H 4361M1/5 Equivalent & Substitute Parts

Part Overview

The 4361M1/5 is an obsolete through-hole LED indicator manufactured by Visual Communications Company (VCC). This dual-color LED provides green and red indication in a diffused lens package with radial 3-lead configuration. The part is no longer in active production, making equivalent substitutes necessary for ongoing maintenance, repair, and new design applications requiring compatible performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4361M1/5 is determined by the following critical parameters:

Electrical Compatibility:

• Forward voltage (Vf): 2.1V Green, 2V Red
• Test current: 20mA Green, 20mA Red
• Dual-color configuration (Green and Red)

Mechanical Compatibility:

• Through-hole mounting type
• Radial 3-lead package configuration
• Diffused lens transparency
• Round domed lens style

Environmental & Regulatory:

• ROHS3 compliance
• EAR99 export classification
• HTSUS code 8541.41.0000

The substitute part 3BC-3-CA-F from Bivar Inc. meets all critical electrical and mechanical parameters. While differences exist in lens diameter (3mm vs 3.10mm), millicandela rating (6mcd vs 3mcd), viewing angle, and height, these represent performance enhancements rather than incompatibilities. The substitute maintains identical forward voltage, test current, mounting configuration, and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 3BC-3-CA-F from Bivar Inc. is the qualified substitute for the obsolete 4361M1/5. Selection is based on the following engineering criteria:

Electrical Equivalence: Forward voltage and test current specifications are identical across both green and red channels, ensuring direct circuit compatibility without modification to current-limiting resistor values or power supply requirements.

Mechanical Fit: Both parts utilize through-hole radial 3-lead configuration with identical package classification. The 3BC-3-CA-F features a reduced maximum height (5.30mm vs 7.59mm), which provides improved PCB layout flexibility without compromising mounting compatibility.

Regulatory Compliance: Both parts maintain ROHS3 compliance and share identical HTSUS and ECCN classifications, ensuring equivalent supply chain and regulatory status.

Product Availability: The 3BC-3-CA-F is in active production with substantial inventory availability (25,150 pcs), whereas the 4361M1/5 is obsolete. The substitute part carries improved moisture sensitivity rating (MSL 1 vs MSL 2), providing superior long-term reliability in storage and field conditions.

Performance Considerations: The 3BC-3-CA-F delivers enhanced brightness (6mcd vs 3mcd) with a narrower viewing angle (45° vs 70°/60°). These characteristics represent performance improvements suitable for applications requiring higher visibility or more directional indication.

Frequently Asked Questions (FAQ)

Q: Can the 3BC-3-CA-F directly replace the 4361M1/5 in existing circuit designs?

A: Yes. Both parts share identical forward voltage (2.1V Green, 2V Red) and test current (20mA) specifications. No circuit modifications are required. Existing current-limiting resistor values and power supply connections remain valid.

Q: What is the difference in lens diameter between these parts?

A: The 4361M1/5 has a 3.10mm diameter lens, while the 3BC-3-CA-F has a 3mm diameter lens. This 0.10mm difference is negligible for standard through-hole PCB applications and does not affect mechanical mounting or electrical performance.

Q: Why does the 3BC-3-CA-F have a narrower viewing angle?

A: The 3BC-3-CA-F specifies a 45° viewing angle compared to the 4361M1/5 (70° Green, 60° Red). This narrower angle is a characteristic of the Bivar design and may require consideration in applications where wide-angle visibility is critical. The enhanced brightness (6mcd vs 3mcd) compensates for directional concentration.

Q: Are there any height constraints I should consider?

A: The 3BC-3-CA-F is shorter (5.30mm max height vs 7.59mm). This reduction improves clearance in space-constrained PCB layouts. Verify that your PCB design does not rely on the original height specification before substitution.

Q: What is the moisture sensitivity difference?

A: The 4361M1/5 carries MSL 2 (1 Year), while the 3BC-3-CA-F carries MSL 1 (Unlimited). The substitute part has superior moisture resistance, reducing risk during storage and field deployment.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the 4361M1/5 and 3BC-3-CA-F are ROHS3 compliant and share identical HTSUS and ECCN classifications, ensuring equivalent regulatory and supply chain status.

Q: What is the radial 3-lead configuration?

A: Both parts use a radial package with three leads for through-hole mounting. This configuration accommodates the dual-color LED (green and red) with a common cathode or anode connection. Lead spacing and PCB hole pattern are compatible between both parts.
