Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3RC-201-S is determined by the following critical parameters:

• Color: Red
• Lens Size: 3mm, T-1
• Mounting Type: Through Hole (Radial configuration)
• Voltage - Forward (Vf) (Typ): 2.1V
• Millicandela Rating: 2.5mcd
• Package / Case: Radial

The LTL-4211 from Lite-On Inc. meets these core electrical and mechanical substitution criteria, maintaining compatibility with the original circuit requirements while offering an active product status and improved inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The LTL-4211 is an active product with ROHS3 compliance and REACH regulatory status, providing long-term supply chain viability compared to the obsolete 3RC-201-S. Both components share identical forward voltage (2.1V) and millicandela ratings (2.5mcd), meeting the core electrical requirements for direct circuit substitution.

Frequently Asked Questions (FAQ)

Q: Is the LTL-4211 a direct replacement for the 3RC-201-S? A: The LTL-4211 satisfies the critical electrical parameters (2.1V forward voltage, 2.5mcd intensity) and mechanical form factor (3mm T-1 through-hole radial). The primary difference is lens transparency: LTL-4211 features a diffused lens versus the clear lens of the 3RC-201-S, resulting in a wider viewing angle (40° vs 20°).

Q: What is the difference in test current specifications? A: The 3RC-201-S is rated for 20mA test current, while the LTL-4211 operates at 10mA test current. Both maintain identical brightness output (2.5mcd), indicating improved efficiency in the LTL-4211 design.

Q: Does the height difference affect physical mounting? A: The LTL-4211 is 1.45mm taller (6.55mm vs 5.10mm). Verify clearance within your specific PCB assembly and enclosure design before final implementation.

Q: Are there compliance or regulatory differences? A: The LTL-4211 carries ROHS3 compliance and REACH regulatory status, providing enhanced environmental and regulatory alignment compared to the obsolete 3RC-201-S.
