Engineering Selection Recommendations

APTD3216SURCK (Kingbright) - Primary Recommendation

APTD3216SURCK is the manufacturer-recommended substitute for APTD3216SRCPRV. Both components share identical Kingbright manufacturing lineage and are classified under the same base product number APTD3216. This part maintains active product status with 4285 units in stock. The forward voltage increases from 1.85V to 1.95V, representing a 5.4% increase within acceptable circuit design tolerances. Brightness increases from 150mcd to 800mcd, providing enhanced indication visibility. Wavelength shifts from 640nm to 630nm dominant, remaining within the red spectrum range. Mechanical dimensions and compliance certifications remain identical. Tape & Reel packaging provides production-ready format.

XZMDK55W-3 (SunLED) - Secondary Recommendation

XZMDK55W-3 provides cross-manufacturer substitution with SunLED as alternative source. This part matches the forward voltage of APTD3216SURCK at 1.95V and maintains identical wavelength at 630nm dominant. Brightness rating of 795mcd closely aligns with APTD3216SURCK. Height reduces from 1.90mm to 1.80mm maximum, remaining within acceptable PCB assembly clearance parameters. All compliance certifications and electrical test parameters remain consistent. Active product status with 2900 units in stock ensures procurement availability.

XZM2ACR55W-3 (SunLED) - Alternative for High-Brightness Applications

XZM2ACR55W-3 serves applications requiring enhanced brightness output. This part delivers 2690mcd, substantially exceeding the original 150mcd specification. Forward voltage increases to 2.2V, requiring circuit design verification for compatibility with existing current-limiting resistor values. Wavelength shifts to 625nm dominant, representing the shortest wavelength among substitutes while remaining within red spectrum classification. Height reduces to 1.80mm. Active product status with 18510 units in stock provides maximum procurement flexibility. This substitute is suitable only when increased brightness does not conflict with circuit design constraints.

Frequently Asked Questions (FAQ)

Q: Can APTD3216SURCK directly replace APTD3216SRCPRV without circuit modification?

A: APTD3216SURCK maintains identical mechanical footprint and mounting characteristics. Forward voltage increases from 1.85V to 1.95V. If the original circuit uses a fixed current-limiting resistor, the 0.1V increase will reduce LED current by approximately 5%. For applications where brightness variation is acceptable, direct substitution is viable. For applications requiring constant brightness, resistor recalculation is necessary.

Q: What are the wavelength differences between substitute parts?

A: APTD3216SRCPRV operates at 640nm dominant wavelength. APTD3216SURCK and XZMDK55W-3 both operate at 630nm dominant wavelength. XZM2ACR55W-3 operates at 625nm dominant wavelength. All wavelengths remain within the red LED spectrum. Visual color perception differences are minimal across this range for human observation applications.

Q: Are all substitute parts RoHS3 compliant?

A: All substitute parts listed—APTD3216SURCK, XZMDK55W-3, and XZM2ACR55W-3—are ROHS3 compliant with REACH Unaffected status, matching the compliance profile of APTD3216SRCPRV.

Q: What is the impact of brightness differences on circuit design?

A: APTD3216SRCPRV operates at 150mcd. APTD3216SURCK and XZMDK55W-3 operate at approximately 800mcd and 795mcd respectively, representing 5.3x brightness increase. XZM2ACR55W-3 operates at 2690mcd, representing 17.9x brightness increase. If the original circuit design relies on specific brightness output for visual indication, substitute selection must account for these differences. Higher brightness may require reduced forward current through resistor adjustment to prevent over-driving the LED.

Q: Can XZM2ACR55W-3 be used in all applications where APTD3216SRCPRV was used?

A: XZM2ACR55W-3 differs in three parameters: forward voltage (2.2V vs 1.85V), brightness (2690mcd vs 150mcd), and wavelength (625nm vs 640nm). Circuit compatibility depends on whether the design accommodates 0.35V higher forward voltage and whether the application tolerates significantly increased brightness. Direct substitution without circuit analysis is not recommended for this part.

Q: What is the difference between Tape & Reel and Chip LED packaging?

A: APTD3216SURCK is supplied in Tape & Reel (TR) format, standard for automated assembly processes. XZMDK55W-3 and XZM2ACR55W-3 are supplied as Chip LED format. Both formats contain identical electrical and optical components; packaging format affects only handling and assembly methodology.

Q: Are there height clearance considerations when substituting?

A: APTD3216SRCPRV has maximum height of 1.90mm. APTD3216SURCK maintains 1.90mm height. XZMDK55W-3 and XZM2ACR55W-3 reduce to 1.80mm maximum height. Both heights remain within standard PCB assembly clearance specifications. Height reduction may provide marginal benefit in space-constrained designs.
