APT2012PR54F/A-SC Equivalent & Substitute Parts

Part Overview

The APT2012PR54F/A-SC is an ice blue diffused LED indication component manufactured by Kingbright, designed for surface mount applications in the 0805 (2012 Metric) package format. This active product operates at a forward voltage of 3.2V with a test current of 20mA, delivering 120mcd luminous intensity through a fluorescent green diffused lens. The component is RoHS3 compliant and REACH unaffected, suitable for standard LED indication circuits requiring ice blue spectral output.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across alternative configurations, particularly when addressing component availability, package size optimization, or specific application constraints.

Substitute Part Grouping Explanation

Substitute part identification for the APT2012PR54F/A-SC is based on the following electrical and mechanical compatibility criteria:

Primary Substitution Criteria:

• Surface mount mounting type
• Active product status with current manufacturing availability
• RoHS3 compliance and REACH unaffected regulatory status
• Forward voltage within acceptable operating range (3.0V to 3.5V)
• Test current specification of 20mA
• Luminous intensity sufficient for indication applications (minimum 60mcd)
• Viewing angle of 140° or greater

Secondary Compatibility Factors:

• Package format optimization (0402 and 0805 packages both acceptable for standard PCB layouts)
• Lens configuration (clear or diffused acceptable for indication purposes)
• Moisture sensitivity level MSL 3 or better

The substitute part APHHS1005QBC/D meets these criteria through equivalent electrical performance, identical regulatory compliance, and compatible surface mount configuration, despite differences in package size, color specification, and lens transparency.

Engineering Selection Recommendations

APT2012PR54F/A-SC is the primary selection when ice blue spectral output with diffused lens characteristics is required. The component maintains active product status with confirmed manufacturing availability (898 pcs in stock). RoHS3 compliance and REACH unaffected status confirm regulatory alignment for current and future applications.

APHHS1005QBC/D serves as a functional substitute when package size reduction is a design requirement or when component availability constraints necessitate alternative sourcing. This substitute maintains equivalent electrical performance through identical forward voltage range (3.3V vs 3.2V nominal), matching test current specification (20mA), and identical regulatory compliance (RoHS3, REACH unaffected, MSL 3). The substitute provides 60mcd luminous intensity and 140° viewing angle, both within acceptable ranges for standard indication applications. The 0402 package format enables space-constrained PCB layouts while preserving surface mount compatibility.

Selection between these components depends on specific application requirements for spectral output (ice blue vs blue), lens transparency (diffused vs clear), and available PCB real estate for component placement.

Frequently Asked Questions (FAQ)

Q: Can APHHS1005QBC/D directly replace APT2012PR54F/A-SC in existing designs?

A: Direct replacement requires verification of three factors: (1) PCB layout accommodation of the smaller 0402 package (1.00mm L x 0.50mm W vs 2.00mm L x 1.25mm W), (2) acceptance of blue spectral output instead of ice blue, and (3) confirmation that 60mcd luminous intensity meets application brightness requirements versus the original 120mcd specification.

Q: What are the electrical compatibility constraints?

A: Both components operate at nearly identical forward voltages (3.2V vs 3.3V) with matching 20mA test current specifications. Circuit designs using current-limiting resistors calculated for 3.2V operation require minimal adjustment for the 3.3V substitute, with resistor value changes typically less than 5%.

Q: Are there regulatory compliance differences?

A: No. Both components maintain identical RoHS3 compliance status and REACH unaffected classification. Moisture sensitivity level (MSL 3, 168 hours) is identical, requiring equivalent handling and storage protocols.

Q: How do viewing angle differences affect application suitability?

A: The APT2012PR54F/A-SC provides 160° viewing angle versus 140° for APHHS1005QBC/D. For standard indication applications with centered viewing geometry, this 20° difference is typically not functionally significant. Applications requiring wide-angle visibility should retain the original component.

Q: What packaging format differences exist?

A: APT2012PR54F/A-SC uses 0805 (2012 Metric) package; APHHS1005QBC/D uses 0402 (1005 Metric) package. The 0402 format is approximately 50% smaller in footprint area, enabling higher component density but requiring more precise placement equipment and handling procedures.
