Equivalent & Substitute Parts for 5SURC-F

Part Overview

The 5SURC-F is a red LED indicator manufactured by Bivar Inc., designed for through-hole mounting applications. This component features a clear lens with a 5mm T-1 3/4 form factor and delivers 500mcd brightness at 1.8V forward voltage. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5SURC-F is determined by the following criteria:

Mechanical Compatibility:

• Identical lens size (5mm, T-1 3/4)
• Identical mounting type (Through Hole)
• Identical package configuration (Radial)
• Maximum height within 8.60mm specification

Electrical Compatibility:

• Red color emission
• Forward voltage within acceptable circuit design parameters
• Test current of 20mA
• Wavelength in the red spectrum range

Operational Compatibility:

• Viewing angle suitable for indication applications
• Brightness level appropriate for visual indication

The 5RD-F meets the mechanical compatibility requirements and shares the same lens size, mounting type, and package configuration. However, electrical parameters differ: the 5RD-F operates at 2.1V forward voltage (versus 1.8V), produces 1.5mcd brightness (versus 500mcd), and features a diffused red lens (versus clear lens). These differences must be evaluated against specific circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

5SURC-F Status: Obsolete product with 1011 units in current inventory.

5RD-F Consideration: Active product status with ROHS3 compliance certification. This part maintains mechanical and mounting compatibility with the 5SURC-F through identical lens size (5mm T-1 3/4), radial package configuration, and through-hole mounting. Both components are manufactured by Bivar Inc.

Critical Differences Requiring Circuit Evaluation:

The 5RD-F operates at 2.1V forward voltage compared to the 5SURC-F at 1.8V. This 0.3V difference affects series resistor calculations and power supply compatibility. The 5RD-F produces 1.5mcd brightness versus 500mcd for the 5SURC-F, representing a significant reduction in light output. The 5RD-F features a diffused red lens and red lens color, whereas the 5SURC-F has a clear colorless lens. These optical differences alter the visual appearance and light distribution characteristics.

Selection of the 5RD-F as a substitute requires confirmation that the circuit design accommodates the higher forward voltage and that the reduced brightness and diffused optical characteristics meet application requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5RD-F directly replace the 5SURC-F in existing designs?

A: Mechanical and mounting compatibility exists due to identical lens size (5mm T-1 3/4), radial package, and through-hole configuration. However, electrical parameter differences require circuit evaluation. The 5RD-F operates at 2.1V versus 1.8V and produces 1.5mcd versus 500mcd brightness.

Q: What are the key differences between these two parts?

A: The 5SURC-F features a clear colorless lens with 500mcd brightness at 1.8V. The 5RD-F features a diffused red lens with 1.5mcd brightness at 2.1V. Both share identical physical dimensions and mounting type.

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

A: The 5RD-F carries ROHS3 compliance certification. The 5SURC-F compliance status is not specified in available documentation.

Q: How do the optical characteristics differ?

A: The 5SURC-F provides a clear lens with focused light output at 35° viewing angle. The 5RD-F provides a diffused red lens with broader 40° viewing angle and significantly reduced brightness output.

Q: What forward voltage should be used for circuit design?

A: The 5SURC-F operates at 1.8V typical forward voltage. The 5RD-F operates at 2.1V typical forward voltage. Series resistor values must be recalculated for any substitution.

Q: Are both parts available for new procurement?

A: The 5SURC-F is obsolete with 1011 units in inventory. The 5RD-F is active product status with 827 units in inventory.
