Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the 3RC5V-S is determined by the following critical parameters:

Primary Compatibility Criteria:

• Color: Red
• Lens Size: 3mm, T-1
• Mounting Type: Through Hole
• Voltage - Forward (Vf): 5V
• Package / Case: Radial
• Lens Style: Round with Domed Top

Secondary Compatibility Parameters:

• Current - Test: 8mA (allowable range for circuit integration)
• Viewing Angle: 30° (minimum acceptable for indication applications)
• Millicandela Rating: 2.5mcd (minimum brightness for visibility)
• Height (Max): 6.10mm (physical clearance constraint)

The substitute part WP710A10ID5V meets all primary compatibility criteria and operates within acceptable ranges for secondary parameters, enabling direct functional replacement in through-hole red LED indication circuits designed for 5V operation.

Parameter Comparison

Engineering Selection Recommendations

The WP710A10ID5V from Kingbright is a functionally compatible substitute for the obsolete 3RC5V-S. Both components share identical mechanical form factors (T-1, 3mm, through-hole radial), identical forward voltage (5V), and equivalent moisture sensitivity ratings (MSL 1).

The WP710A10ID5V is classified as Active product status, ensuring ongoing availability and supply chain continuity. The component is RoHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component procurement.

Differences in test current (13mA vs. 8mA), millicandela rating (14mcd vs. 2.5mcd), viewing angle (40° vs. 30°), and wavelength characteristics (627nm peak vs. 700nm peak) reflect design improvements in the substitute part. These differences result in enhanced brightness and wider viewing angle, which are compatible with applications originally designed for the 3RC5V-S.

Physical height is within acceptable tolerance (5.90mm vs. 6.10mm maximum), confirming PCB clearance compatibility.

Frequently Asked Questions (FAQ)

Q: Can the WP710A10ID5V directly replace the 3RC5V-S in existing circuit designs?

A: Yes. Both components operate at 5V forward voltage, use identical T-1 (3mm) through-hole radial packages, and share the same mechanical form factor. Circuit designs do not require modification for physical or electrical integration.

Q: What is the significance of the higher millicandela rating in the WP710A10ID5V?

A: The WP710A10ID5V provides 14mcd brightness compared to 2.5mcd in the 3RC5V-S. This represents enhanced luminous intensity, resulting in improved visibility for indication applications. Existing circuits will function with this increased brightness without adverse effects.

Q: Does the difference in test current (13mA vs. 8mA) affect circuit compatibility?

A: Test current specifications indicate the current at which brightness is measured. Circuit designs must be evaluated based on actual operating current determined by series resistor values and supply voltage. The WP710A10ID5V operates at 5V forward voltage, matching the original specification. Current-limiting resistors should be selected based on desired brightness and circuit requirements.

Q: Why is the wavelength different between the two parts?

A: The 3RC5V-S has a peak wavelength of 700nm (red spectrum), while the WP710A10ID5V has a peak wavelength of 627nm (red spectrum). Both are red LEDs suitable for indication applications. The wavelength difference reflects manufacturing process variations between manufacturers and does not affect functional compatibility in standard indication circuits.

Q: Is the WP710A10ID5V available in the same packaging as the 3RC5V-S?

A: Yes. The WP710A10ID5V is supplied in bulk packaging, while the 3RC5V-S was supplied in standard packaging. Both use identical T-1 (3mm) through-hole radial component packages suitable for PCB assembly.

Q: What compliance certifications apply to the WP710A10ID5V?

A: The WP710A10ID5V is RoHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component procurement and use.
