Engineering Selection Recommendations

Primary Substitute: APHBM2012SURKSYKC

The APHBM2012SURKSYKC is the qualified substitute for the obsolete APB2012SURKSYKC. Selection rationale is based on the following engineering factors:

Compliance & Regulatory:

• Both components maintain ROHS3 compliance
• Both components maintain REACH Unaffected status
• Identical Moisture Sensitivity Level (MSL 3, 168 Hours)

Electrical Compatibility:

• Identical forward voltage specifications (1.95V Red, 2V Yellow)
• Identical test current specifications (20mA Red, 20mA Yellow)
• Wavelength specifications remain within acceptable red and yellow spectrum ranges

Physical & Mechanical Compatibility:

• Identical 0805 (2012 Metric) package footprint
• Identical mounting type (Surface Mount)
• Identical lens dimensions (1.30mm x 1.25mm)
• Reduced maximum height (0.45mm vs 1.10mm) provides improved PCB clearance

Product Availability:

• APHBM2012SURKSYKC maintains Active product status with 962 units in stock
• APB2012SURKSYKC is Obsolete with limited remaining inventory (667 units)

Configuration Difference: The APHBM2012SURKSYKC uses Independent configuration versus the Bidirectional configuration of the original part. This difference affects internal LED connection topology but does not impact electrical performance when used in standard indicator applications with separate current-limiting resistors for each color.

Frequently Asked Questions (FAQ)

Q: Can APHBM2012SURKSYKC directly replace APB2012SURKSYKC in existing designs?

A: Yes, for applications using standard indicator circuit topologies with independent current-limiting resistors for each LED color. The Independent configuration of the substitute part is electrically compatible with Bidirectional circuit implementations when each color path includes its own current-limiting resistor and anode/cathode connections.

Q: What is the difference between Bidirectional and Independent configuration?

A: Bidirectional configuration uses a common cathode or anode connection for both LEDs. Independent configuration provides separate connections for each LED. Both configurations support dual-color indication; the difference lies in internal connection topology. The substitute part's Independent configuration requires separate current paths but maintains identical electrical performance specifications.

Q: Are the brightness differences significant?

A: The APHBM2012SURKSYKC provides higher brightness ratings (200mcd Red, 150mcd Yellow) compared to the original (80mcd Red, 120mcd Yellow). This enhancement improves visibility without affecting circuit compatibility. Applications requiring the original brightness levels should account for this increased output through circuit design adjustments if necessary.

Q: Does the reduced height of the substitute part affect PCB layout?

A: The APHBM2012SURKSYKC has a maximum height of 0.45mm compared to 1.10mm for the original part. This reduction provides additional PCB clearance and may improve solder joint reliability. No layout modifications are required; the reduced height is a beneficial characteristic.

Q: Are wavelength differences significant?

A: Red wavelength shifts from 630nm (dominant) to 635nm (dominant), with peak wavelength shifting from 645nm to 650nm. Yellow wavelength remains at 590nm. These shifts remain within standard red and yellow LED spectrum ranges and do not affect visual color perception or application compatibility.

Q: What is the viewing angle difference impact?

A: The original part provides 150° viewing angle; the substitute provides 120° viewing angle. The 30° reduction narrows the optimal viewing cone but remains suitable for standard indicator applications. Applications requiring wide-angle visibility should evaluate this specification against specific requirements.

Q: Are both parts RoHS and REACH compliant?

A: Yes, both APB2012SURKSYKC and APHBM2012SURKSYKC are ROHS3 Compliant and REACH Unaffected, maintaining identical regulatory compliance status.
