APT2012PBC/A Equivalent & Substitute Parts

Part Overview

The APT2012PBC/A is a blue LED indication component manufactured by Kingbright, featuring a 470nm dominant wavelength and 60mcd brightness rating in a 0805 (2012 Metric) surface mount package. This part is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. The component operates at 3.2V forward voltage with a 20mA test current and provides a 120° viewing angle in a clear lens configuration.

Due to its obsolete status, substitute parts must maintain compatibility across mechanical mounting, electrical performance, and optical characteristics to ensure direct replacement capability in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the APT2012PBC/A are qualified based on the following mandatory compatibility criteria:

Mechanical Compatibility:

• Package / Case: 0805 (2012 Metric) - all substitutes must match this footprint
• Mounting Type: Surface Mount - required for PCB assembly compatibility
• Lens Style: Rectangle with Flat Top - optical housing consistency
• Size / Dimension: 2.00mm L x 1.25mm W - PCB layout compatibility
• Height (Max): ≤0.90mm - clearance and assembly tolerance

Electrical Compatibility:

• Color: Blue - functional requirement for indication circuits
• Wavelength - Dominant: 460-471nm range - acceptable blue spectrum for visual indication
• Voltage - Forward (Vf): 3.2V to 3.3V - circuit design tolerance
• Current - Test: 20mA - standard test condition
• Viewing Angle: ≥120° - acceptable for indication applications

Regulatory Compliance:

• RoHS3 Compliant - environmental and safety requirement
• REACH Status: REACH Unaffected or compliant - regulatory alignment

All three substitute parts meet these criteria and are classified as active products, providing long-term availability assurance.

Parameter Comparison

Engineering Selection Recommendations

APT2012QBC/D (Kingbright)

This substitute maintains manufacturer continuity with the original APT2012PBC/A while offering active product status. The forward voltage increases from 3.2V to 3.3V, requiring circuit verification for voltage-sensitive applications. Brightness increases to 100mcd, providing enhanced visibility. Wavelength shifts from 470nm to 465nm, remaining within acceptable blue spectrum range. This part is recommended for designs where manufacturer consistency and higher brightness are acceptable trade-offs.

XZCBD54W-1 (SunLED)

This substitute provides the highest brightness rating at 98mcd with wavelength characteristics (465nm dominant, 460nm peak) matching the APT2012QBC/D. Forward voltage is 3.3V. Viewing angle remains at 120°, identical to the original part. Moisture sensitivity level matches the original specification. This part offers the largest inventory availability (8129 pcs) and is supplied in Tape & Reel packaging, supporting high-volume production requirements.

EAST20128BA1 (Everlight Electronics Co Ltd)

This substitute offers the lowest brightness rating at 50mcd with wavelength closest to the original at 471nm dominant. Forward voltage is 3.3V. The viewing angle expands to 130°, providing wider visibility. Moisture sensitivity level improves to MSL 2 (1 Year), offering superior moisture protection. This part is suitable for applications where lower brightness is acceptable and extended moisture protection is required.

Compliance Basis:

All three substitutes maintain ROHS3 compliance and EAR99 ECCN classification, ensuring regulatory alignment with the original part. Selection should prioritize application-specific requirements for brightness, voltage tolerance, and moisture sensitivity rather than manufacturer preference alone.

Frequently Asked Questions (FAQ)

Q: Can APT2012QBC/D directly replace APT2012PBC/A in existing designs?

A: Direct replacement is mechanically and optically compatible. The forward voltage increases from 3.2V to 3.3V, requiring circuit analysis to confirm the additional 0.1V does not exceed design margins. Brightness increases from 60mcd to 100mcd, which is acceptable for indication applications. Wavelength shifts from 470nm to 465nm, remaining within blue spectrum range.

Q: What is the primary difference between XZCBD54W-1 and APT2012QBC/D?

A: Both parts share identical electrical characteristics (3.3V forward voltage, 465nm dominant wavelength, 120° viewing angle, 20mA test current). XZCBD54W-1 offers slightly higher brightness at 98mcd versus 100mcd. The primary distinction is manufacturer (SunLED versus Kingbright) and packaging format (Tape & Reel versus standard). XZCBD54W-1 provides significantly higher inventory availability.

Q: Why does EAST20128BA1 have a different height specification?

A: EAST20128BA1 specifies a maximum height of 0.90mm compared to 0.75mm for other substitutes. This 0.15mm difference results from manufacturing process variations between Everlight and other manufacturers. For most PCB designs with standard clearance tolerances, this difference is acceptable. Applications with tight vertical clearance constraints should confirm compatibility with board layout specifications.

Q: Is the 0.1V forward voltage difference between 3.2V and 3.3V critical?

A: The 0.1V difference is within typical circuit design tolerance for LED indication applications. Current-limiting resistor values should be recalculated if the circuit was optimized for 3.2V operation. For most standard indication circuits, the difference is negligible. Applications with precision current control or battery-powered designs operating near voltage limits should perform detailed circuit analysis.

Q: What does MSL 2 versus MSL 3 mean for component handling?

A: MSL (Moisture Sensitivity Level) 2 allows 1 year of dry storage before reflow soldering, while MSL 3 allows 168 hours (7 days). EAST20128BA1 with MSL 2 provides extended shelf life and reduced risk of moisture-induced defects during storage and assembly. For high-volume production with standard inventory rotation, this difference is typically not significant. Long-term storage applications should prioritize MSL 2 rated components.

Q: Can these substitutes be mixed in the same production batch?

A: All three substitutes are mechanically and electrically compatible for the same PCB footprint and circuit function. Mixing different manufacturers in a single production batch is acceptable from a technical standpoint. However, supply chain and quality control procedures should document which substitute is used in each batch for traceability and future service requirements.

Q: Which substitute offers the best long-term availability?

A: XZCBD54W-1 currently shows the highest inventory level at 8129 pcs. APT2012QBC/D and EAST20128BA1 show 2200 pcs and 870 pcs respectively. Long-term availability depends on manufacturer production schedules and market demand, which are not provided in current data.
