APT3216ZGC Equivalent & Substitute Parts

Part Overview

The APT3216ZGC is an active-status green LED indication component manufactured by Kingbright, designed for surface mount applications in the 1206 (3216 Metric) package format. This discrete LED operates at 3.3V forward voltage with a 20mA test current and delivers 400mcd brightness at 525nm dominant wavelength. The component is supplied in Tape & Reel packaging with 26,100 pieces currently in stock.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the same package category, mounting type, and core functional parameters. Alternative sources become necessary for supply chain continuity, inventory management, or design flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the APT3216ZGC is determined by strict alignment across the following critical parameters:

Package Compatibility: All substitute parts must use the 1206 (3216 Metric) surface mount package with identical footprint dimensions (3.20mm L x 1.60mm W).

Optical Characteristics: Substitute parts must be green LEDs with clear lens transparency and operate within the visible green spectrum (dominant wavelength 525nm or peak wavelength in the 515–565nm range).

Electrical Parameters: Forward voltage (Vf) must be within ±0.2V of the main part specification (3.3V nominal), and test current must be 20mA to ensure circuit compatibility.

Compliance & Certification: All substitute parts must maintain ROHS3 compliance, MSL Level 3 rating, and active product status to ensure long-term availability and regulatory alignment.

Mechanical Constraints: Height specifications must not exceed 1.23mm to accommodate standard PCB assembly processes and clearance requirements.

The identified substitute parts meet these criteria while maintaining functional equivalence for indication applications.

Parameter Comparison

Engineering Selection Recommendations

LTST-C150TGKT (Lite-On Inc.): This substitute maintains the closest electrical alignment with forward voltage of 3.2V (0.1V variance from APT3216ZGC) and identical 20mA test current. Both parts operate at 525nm dominant wavelength with comparable spectral characteristics. The LTST-C150TGKT delivers 260.5mcd brightness with a 130° viewing angle, providing broader light distribution than the main part. Height specification of 1.10mm remains within standard PCB assembly tolerances. ROHS3 compliance and MSL Level 3 rating ensure regulatory and environmental compatibility. This part is suitable for direct substitution in applications where brightness reduction from 400mcd to 260.5mcd is acceptable.

SML-LX1206GC-TR1 (Lumex Opto/Components Inc.): This substitute operates at significantly lower forward voltage (2.2V) and delivers substantially reduced brightness (10mcd). The peak wavelength of 565nm represents a shift toward the yellow-green spectrum compared to the 525nm dominant wavelength of the main part. This part is suitable only for applications where lower brightness is required or where circuit voltage constraints necessitate reduced forward voltage operation. The 125° viewing angle and 1.23mm maximum height remain compatible with standard surface mount assembly. ROHS3 compliance and MSL Level 3 rating are maintained.

All substitute parts maintain active product status and full regulatory compliance, ensuring long-term component availability and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can LTST-C150TGKT replace APT3216ZGC in all applications?

A: LTST-C150TGKT is electrically compatible with forward voltage of 3.2V versus 3.3V and identical 20mA test current. The primary difference is reduced brightness (260.5mcd versus 400mcd). Substitution is valid for applications where this brightness level is acceptable. Both parts share identical package dimensions, mounting type, and compliance certifications.

Q: What are the key differences between APT3216ZGC and SML-LX1206GC-TR1?

A: SML-LX1206GC-TR1 operates at 2.2V forward voltage (1.1V lower than APT3216ZGC) and produces only 10mcd brightness compared to 400mcd. The peak wavelength is 565nm versus 515nm for the main part, representing a shift toward yellow-green. This part is suitable only for applications with specific voltage constraints or where minimal brightness is required.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All three parts use the 1206 (3216 Metric) package with identical footprint dimensions of 3.20mm length by 1.60mm width. Height variations (0.75mm, 1.10mm, and 1.23mm maximum) remain within standard surface mount assembly clearance specifications.

Q: Do substitute parts maintain the same compliance certifications?

A: Yes. All substitute parts are ROHS3 compliant, carry MSL Level 3 (168 Hours) moisture sensitivity rating, and maintain active product status. REACH and ECCN classifications are identical across all parts.

Q: What is the primary substitution criterion for green 1206 LEDs?

A: The primary criteria are package compatibility (1206 surface mount), forward voltage alignment (±0.2V tolerance), test current (20mA), and wavelength range (green spectrum, 515–565nm). Brightness level and viewing angle are secondary parameters that may vary based on application requirements.

Q: Can SML-LX1206GC-TR1 be used in high-brightness indication applications?

A: No. SML-LX1206GC-TR1 produces only 10mcd brightness, which is insufficient for standard indication applications requiring 260mcd or higher. This part is limited to low-brightness or specialty applications where minimal light output is required.

Q: What inventory considerations apply to these substitute parts?

A: APT3216ZGC has 26,100 pieces in stock. LTST-C150TGKT has significantly higher availability at 406,030 pieces. SML-LX1206GC-TR1 has 10,803 pieces available. Inventory levels may influence substitution decisions for high-volume production requirements.
