APT2012SRCPRV Equivalent & Substitute Parts

Part Overview

The APT2012SRCPRV is a red LED indication component manufactured by Kingbright in 0805 (2012 Metric) surface mount package. This discrete LED operates at 1.85V forward voltage with a dominant wavelength of 640nm and provides 30mcd luminous intensity. The component is classified as obsolete product status, necessitating identification of active equivalent parts for ongoing design requirements and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the APT2012SRCPRV is determined by strict compatibility across the following parameters:

Mandatory Compatibility Parameters:

• Package / Case: 0805 (2012 Metric) — physical footprint and mounting interface
• Mounting Type: Surface Mount — assembly process compatibility
• Color: Red — optical output specification
• Lens Transparency: Clear — optical characteristic
• Viewing Angle: 120° — directional light emission
• Size / Dimension: 2.00mm L x 1.25mm W — PCB layout constraint
• Height (Max): 0.75mm — clearance requirement

Allowable Variation Parameters:

• Voltage - Forward (Vf) (Typ): Within circuit design tolerance
• Millicandela Rating: Brightness variation acceptable if circuit design permits
• Wavelength - Dominant: Red spectrum variation (630nm to 655nm range)
• Product Status: Active status preferred for procurement continuity

The APT2012SURCK meets all mandatory compatibility parameters and represents an active product alternative to the obsolete APT2012SRCPRV.

Parameter Comparison

Engineering Selection Recommendations

The APT2012SURCK is the direct substitute for the obsolete APT2012SRCPRV based on identical mechanical and optical compatibility. Both components share the same 0805 (2012 Metric) package footprint, surface mount assembly process, and optical viewing characteristics.

The APT2012SURCK maintains active product status, ensuring long-term procurement availability and supply chain continuity. Both parts satisfy ROHS3 compliance and REACH unaffected regulatory requirements, supporting equivalent environmental and regulatory qualification.

Differences in forward voltage (1.95V versus 1.85V) and luminous intensity (80mcd versus 30mcd) represent performance enhancements in the substitute part. Circuit designs must accommodate the 0.10V forward voltage increase and higher brightness output. These parameters fall within standard LED circuit design tolerance ranges for series resistor adjustment and current limiting applications.

The APT2012SURCK is supplied in Tape & Reel (TR) packaging format, supporting automated assembly processes. The original APT2012SRCPRV bulk packaging differs only in handling and delivery format, not in component performance or compatibility.

Frequently Asked Questions (FAQ)

Q: Can APT2012SURCK replace APT2012SRCPRV in existing PCB designs without layout modifications?

A: Yes. Both components share identical 0805 (2012 Metric) package dimensions (2.00mm L x 1.25mm W, 0.75mm max height) and surface mount footprint. No PCB layout changes are required.

Q: What is the impact of the 0.10V forward voltage difference between the two parts?

A: The APT2012SURCK operates at 1.95V compared to the APT2012SRCPRV at 1.85V. This difference affects series resistor calculations in current-limiting circuits. Circuit designs must be verified to confirm the higher forward voltage remains within the power supply voltage margin and does not exceed maximum circuit voltage specifications.

Q: Does the higher millicandela rating (80mcd versus 30mcd) affect circuit compatibility?

A: The APT2012SURCK provides increased luminous intensity at the same 20mA test current. Circuit current limiting and power supply requirements remain unchanged. Visual brightness will increase; circuit designs must confirm this enhanced brightness is acceptable for the application.

Q: Are the wavelength differences (640nm dominant versus 630nm dominant) significant?

A: Both wavelengths fall within the red LED spectrum. The APT2012SRCPRV at 640nm and APT2012SURCK at 630nm represent different red hues. Applications requiring specific color matching or spectral filtering must evaluate whether the wavelength shift is acceptable.

Q: What is the difference between bulk packaging and Tape & Reel (TR) packaging?

A: Bulk packaging (APT2012SRCPRV) is supplied in loose component format. Tape & Reel (TR) packaging (APT2012SURCK) is supplied on continuous tape for automated pick-and-place assembly. Both formats contain identical components; packaging format affects handling, storage, and assembly process only.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both APT2012SRCPRV and APT2012SURCK are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Why is APT2012SRCPRV classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The APT2012SURCK represents the active equivalent, ensuring continued availability for new designs and procurement requirements.
