LED RED CLEAR T-1 3/4 T/H 5RC-F Equivalent & Substitute Parts

Part Overview

The 5RC-F is a red LED indicator manufactured by Bivar Inc., designed for through-hole mounting applications requiring discrete red light indication. This component features a clear lens with a 5mm T-1 3/4 form factor and operates at a forward voltage of 2.1V with a test current of 20mA.

The 5RC-F is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing maintenance, repair, and new design requirements where this part is specified or functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5RC-F is evaluated based on strict electrical and mechanical compatibility criteria. The following parameters must align for a component to function as a direct substitute:

Mandatory Matching Parameters:

• Voltage - Forward (Vf): 2.1V (electrical circuit compatibility)
• Current - Test: 20mA (operating point compatibility)
• Lens Size: 5mm, T-1 3/4 (mechanical fit)
• Mounting Type: Through Hole (assembly compatibility)
• Package / Case: Radial (lead configuration)
• Height (Max): 8.60mm (form factor)
• Wavelength - Peak: 700nm (red color specification)

Allowable Variation Parameters:

• Lens Transparency: Clear or Diffused (affects brightness perception but maintains functional operation)
• Viewing Angle: Variation within application tolerance (affects light distribution pattern)
• Millicandela Rating: Minor variation acceptable if application brightness requirements are met

The 5RD-F meets all mandatory matching criteria and is identified as a direct substitute for the 5RC-F.

Parameter Comparison

Engineering Selection Recommendations

The 5RD-F is a qualified substitute for the obsolete 5RC-F based on the following engineering criteria:

Electrical Compatibility: Both components operate at identical forward voltage (2.1V) and test current (20mA), ensuring direct circuit compatibility without modification to current-limiting resistor values or power supply specifications.

Mechanical Compatibility: Both components share identical lens size (5mm, T-1 3/4), mounting type (through hole), package configuration (radial), and maximum height (8.60mm), confirming PCB layout and enclosure fit compatibility.

Optical Specification: Both components emit at the same peak wavelength (700nm), maintaining red color specification. The 5RD-F features a diffused lens versus the clear lens of the 5RC-F, resulting in a wider viewing angle (40° vs. 35°) and softer light distribution. The 5RD-F brightness is 1.5mcd compared to 2mcd for the 5RC-F.

Product Status and Compliance: The 5RD-F is in active production with ROHS3 compliance certification, ensuring long-term availability and environmental regulatory alignment. The 5RC-F is obsolete and no longer manufactured.

Selection Criteria: The 5RD-F is suitable for applications where the diffused lens characteristic and slightly reduced brightness are acceptable. Applications requiring maximum brightness or narrow light beam characteristics should evaluate alternative red LED options with comparable brightness ratings.

Frequently Asked Questions (FAQ)

Q: Can the 5RD-F be used as a direct replacement for the 5RC-F without circuit modification?

A: Yes. Both components operate at 2.1V forward voltage and 20mA test current. No changes to current-limiting resistors or power supply specifications are required.

Q: What is the difference between the clear lens of the 5RC-F and the diffused lens of the 5RD-F?

A: The clear lens of the 5RC-F provides a more focused light beam with a 35° viewing angle. The diffused lens of the 5RD-F scatters light more broadly, resulting in a 40° viewing angle and softer light distribution. The diffused lens reduces peak brightness (1.5mcd vs. 2mcd) but improves visibility from wider angles.

Q: Will the 5RD-F fit in the same PCB mounting holes as the 5RC-F?

A: Yes. Both components have identical lens size (5mm, T-1 3/4), radial package configuration, and maximum height (8.60mm). PCB layout and enclosure clearances are compatible.

Q: Is the 5RD-F available in the same packaging as the 5RC-F?

A: The 5RC-F is listed as obsolete with no current packaging specification. The 5RD-F is available in bulk packaging and is in active production.

Q: Does the 5RD-F meet current environmental compliance standards?

A: Yes. The 5RD-F is ROHS3 compliant, meeting current environmental and regulatory requirements. The 5RC-F compliance status is not specified.

Q: What should I consider when selecting between the 5RC-F and 5RD-F?

A: Since the 5RC-F is obsolete, the 5RD-F is the practical choice for new designs and ongoing production. For applications requiring maximum brightness or narrow light beam characteristics, evaluate the brightness difference (1.5mcd vs. 2mcd) and viewing angle (40° vs. 35°) against application requirements. The diffused lens of the 5RD-F is advantageous for applications requiring visibility from multiple angles.
