AP2012EC Red 625nm LED Indication - 0805 SMD Equivalent & Substitute Parts

Part Overview

The AP2012EC is an active production red LED indication component manufactured by Kingbright, designed for surface mount applications in the 0805 (2012 Metric) package format. This discrete LED operates at 2V forward voltage with a 625nm dominant wavelength and 15mcd brightness rating. The component is specified for standard indication applications requiring clear lens optics and 120° viewing angle characteristics.

Substitute parts are identified based on functional compatibility within the red LED indication category, maintaining critical electrical and mechanical parameters that permit direct circuit-level substitution while accounting for minor performance variations in brightness, wavelength, and viewing angle specifications.

• Current - Test: 20mA operating point
• Package / Case: 0805 (2012 Metric) only
• Mounting Type: Surface Mount
• Color: Red spectrum
• RoHS Status: ROHS3 Compliant

Important Parameters (Acceptable Variation):

• Wavelength - Dominant: 617nm to 626nm (red spectrum range)
• Millicandela Rating: 8mcd to 15mcd (brightness tolerance)
• Viewing Angle: 120° to 170° (optical distribution tolerance)
• Lens Transparency: Clear or Diffused (both acceptable for indication)

Identified Substitute Parts:

1. APT2012EC (Kingbright) - Same manufacturer, lower brightness variant
2. CMD17-21VRC/TR8 (Visual Communications Company - VCC) - Wider viewing angle variant
3. HSMS-C170 (Broadcom Limited) - Diffused lens variant with extended viewing angle

Parameter Comparison

Engineering Selection Recommendations

AP2012EC Primary Application: The AP2012EC serves as the reference component for red LED indication circuits operating at 2V with 20mA test current in 0805 surface mount format. All substitute parts maintain active product status and ROHS3 compliance, confirming regulatory compatibility for current production environments.

APT2012EC Selection Criteria: APT2012EC is substitutable when brightness reduction from 15mcd to 8mcd is acceptable within circuit design margins. This variant maintains identical voltage and current specifications with the same 120° viewing angle. The reduced height (0.75mm vs 1.10mm) provides mechanical advantage in space-constrained layouts. Identical MSL rating (3, 168 Hours) ensures equivalent moisture handling during assembly.

CMD17-21VRC/TR8 Selection Criteria: CMD17-21VRC/TR8 is substitutable when expanded viewing angle (140° vs 120°) is required for broader optical distribution. Brightness rating of 13mcd remains within acceptable tolerance of the 15mcd specification. Forward voltage remains at 2V. Improved MSL rating (2, 1 Year) provides superior moisture protection during extended storage. Tape & Reel packaging format differs from Cut Tape specification of the main part.

HSMS-C170 Selection Criteria: HSMS-C170 is substitutable when maximum viewing angle (170°) and diffused lens optics are required for wide-angle indication applications. Forward voltage of 2.1V represents acceptable tolerance within typical circuit design margins. Brightness rating of 10mcd accommodates applications where reduced intensity is acceptable. Diffused lens characteristic (vs clear) produces different visual appearance suitable for applications requiring light diffusion. Superior MSL rating (2A, 4 Weeks) supports demanding moisture-sensitive assembly environments.

Frequently Asked Questions (FAQ)

Q: Can APT2012EC directly replace AP2012EC in existing circuit designs?

A: APT2012EC is electrically compatible at the 2V/20mA operating point and maintains identical 0805 package footprint. The primary difference is reduced brightness (8mcd vs 15mcd). Direct substitution is valid when circuit design does not require the full 15mcd brightness specification. The lower profile (0.75mm vs 1.10mm) may provide mechanical benefits in compact assemblies.

Q: What is the primary advantage of CMD17-21VRC/TR8 over AP2012EC?

A: CMD17-21VRC/TR8 provides expanded viewing angle (140° vs 120°) for applications requiring broader optical distribution. Brightness rating of 13mcd remains close to the 15mcd specification. The component maintains 2V forward voltage compatibility. Packaging format is Tape & Reel rather than Cut Tape, affecting procurement and assembly processes.

Q: When should HSMS-C170 be selected instead of AP2012EC?

A: HSMS-C170 is selected when applications require maximum viewing angle (170°) and diffused lens optics for light distribution. The white diffused lens produces different visual appearance compared to the clear colorless lens of AP2012EC. Forward voltage of 2.1V is within acceptable tolerance for most 2V-rated circuits. Superior moisture sensitivity rating (2A vs 3) supports assembly processes with extended storage intervals.

Q: Are all substitute parts ROHS3 compliant?

A: All identified substitute parts (APT2012EC, CMD17-21VRC/TR8, HSMS-C170) maintain ROHS3 compliance status, confirming regulatory compatibility with current environmental standards and production requirements.

Q: What is the impact of different lens transparency specifications?

A: AP2012EC, APT2012EC, and CMD17-21VRC/TR8 feature clear lens transparency, producing direct color appearance. HSMS-C170 features diffused lens transparency with white lens color, producing scattered light distribution. Clear lenses provide focused indication; diffused lenses provide broader light spread. Selection depends on application requirements for light concentration or distribution.

Q: Do height differences affect PCB assembly compatibility?

A: Height variations (0.75mm to 1.20mm) may affect clearance in space-constrained designs. APT2012EC (0.75mm) provides lowest profile for compact layouts. AP2012EC (1.10mm) and CMD17-21VRC/TR8 (1.20mm) require standard clearance. HSMS-C170 (0.80mm) offers low profile with diffused optics. Verify clearance requirements in specific PCB assembly designs before substitution.

Q: What are the packaging format differences?

A: AP2012EC and APT2012EC are supplied in Cut Tape (CT) & Digi-Reel® format. CMD17-21VRC/TR8 is supplied in Tape & Reel (TR) format. HSMS-C170 is supplied in Cut Tape (CT) & Digi-Reel® format. Packaging format affects procurement quantities, storage, and automated assembly compatibility. Verify assembly equipment compatibility with selected packaging format.
