APT1608PBC/Z Equivalent & Substitute Parts

Part Overview

The APT1608PBC/Z is a blue 470nm LED indication component manufactured by Kingbright in 0603 (1608 Metric) surface mount package. This discrete LED operates at 3.2V forward voltage with 160mcd luminous intensity and 120° viewing angle. The part is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and production continuity. Substitute parts must maintain compatibility across mechanical form factor, optical wavelength range, electrical operating parameters, and mounting specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the APT1608PBC/Z is determined by strict alignment across the following critical parameters:

Mandatory Compatibility Parameters:

• Package / Case: 0603 (1608 Metric) surface mount form factor
• Color: Blue optical output
• Mounting Type: Surface Mount
• Lens Color: Colorless
• Lens Transparency: Clear
• Viewing Angle: 120°
• RoHS Status: ROHS3 Compliant

Electrical Operating Parameters (Allowable Variance):

• Voltage - Forward (Vf): 3.2V nominal (substitutes at 3.3V acceptable within circuit design tolerance)
• Current - Test: 20mA standard test condition
• Wavelength - Dominant: 470nm ±5nm range (465nm to 475nm acceptable)
• Wavelength - Peak: 467nm ±5nm range

Optical Performance Parameters:

• Millicandela Rating: 160mcd nominal (±20mcd variance acceptable for indication applications)

Substitutes are classified into three categories based on parameter alignment:

MFR Recommended: APT1608VBC/D meets all mandatory parameters with minor electrical variance (3.3V vs 3.2V) and improved luminous intensity (180mcd).

Parametric Equivalent: APT1608QBC/G maintains all mandatory parameters with wavelength shift to 465nm dominant and equivalent 160mcd rating.

Direct Manufacturer Alternative: EAST16086BA0 (Everlight Electronics) provides cross-manufacturer equivalence with 471nm wavelength and 158mcd rating.

Similar Alternative: 19-215SUBC/S280/TR8 shares package and form factor but operates at reduced voltage (2.75V) and current (2mA) with significantly lower luminous intensity (20mcd), suitable only for applications with relaxed brightness requirements.

Engineering Selection Recommendations

Primary Substitute: APT1608VBC/D

APT1608VBC/D is the manufacturer-recommended substitute for APT1608PBC/Z. Both components are Kingbright products within the APT1608 base product family. APT1608VBC/D maintains active product status with substantial inventory availability (43,551 pcs). The forward voltage differential (3.3V vs 3.2V) represents a 3% increase within acceptable circuit design tolerance for indication applications. The luminous intensity improvement to 180mcd provides enhanced optical performance. All mandatory parameters align: 0603 package, blue color, colorless clear lens, 120° viewing angle, surface mount configuration, and ROHS3 compliance. Moisture sensitivity level remains at MSL 3 (168 Hours). Tape & Reel packaging supports automated assembly processes.

Secondary Substitute: APT1608QBC/G

APT1608QBC/G serves as parametric equivalent with identical luminous intensity (160mcd) to the original part. Kingbright manufacture ensures supply chain consistency. Active product status with highest inventory availability (84,168 pcs) provides supply security. Wavelength shift to 465nm dominant (within ±5nm acceptable range) maintains blue optical output perception. Forward voltage at 3.3V aligns with APT1608VBC/D. All mechanical and compliance parameters match the original specification. Tape & Reel packaging supports production requirements.

Cross-Manufacturer Alternative: EAST16086BA0

EAST16086BA0 (Everlight Electronics) provides direct cross-manufacturer substitution with active product status. Wavelength at 471nm and luminous intensity at 158mcd remain within acceptable parameters. Forward voltage at 3.3V matches secondary substitute. Moisture sensitivity level improves to MSL 2 (1 Year), providing enhanced storage and handling tolerance. Height specification reduces to 0.70mm (vs 0.75mm), maintaining PCB assembly compatibility. Limited inventory (950 pcs) requires supply chain verification for high-volume applications.

Restricted Alternative: 19-215SUBC/S280/TR8

19-215SUBC/S280/TR8 shares mechanical form factor and package but operates at significantly reduced electrical parameters (2.75V, 2mA) with substantially lower luminous intensity (20mcd). This part is suitable only for applications where brightness requirements are relaxed or where power consumption minimization is critical. The 8-fold reduction in luminous intensity (20mcd vs 160mcd) disqualifies this part for direct replacement in standard indication applications.

Frequently Asked Questions (FAQ)

Q: Can APT1608VBC/D directly replace APT1608PBC/Z without circuit modification?

A: APT1608VBC/D is compatible with APT1608PBC/Z in most indication applications. The forward voltage increase from 3.2V to 3.3V (100mV differential) is within typical circuit design tolerance for LED indication circuits. Current-limiting resistor values may require minor adjustment if the original design operated at the voltage limit. Verify circuit headroom before implementation.

Q: What is the significance of the wavelength difference between APT1608QBC/G (465nm) and the original APT1608PBC/Z (470nm)?

A: Both wavelengths fall within the blue spectrum (typically 450nm to 495nm). The 5nm difference is imperceptible to human vision in indication applications. Both parts produce identical blue color perception. Selection between these parts should be based on inventory availability and supply chain factors rather than optical performance.

Q: Why does EAST16086BA0 have lower moisture sensitivity level (MSL 2 vs MSL 3)?

A: MSL 2 (1 Year) provides extended storage tolerance compared to MSL 3 (168 Hours). This represents improved moisture resistance and reduces risk of moisture-induced failures during extended warehouse storage or in humid environments. EAST16086BA0 offers superior handling flexibility for supply chain management.

Q: Is the 0.05mm height reduction in EAST16086BA0 and 19-215SUBC/S280/TR8 significant for PCB assembly?

A: The height reduction from 0.75mm to 0.70mm is within standard PCB assembly tolerance and does not affect reflow soldering, pick-and-place accuracy, or component placement. Both parts are mechanically compatible with existing PCB designs.

Q: Can 19-215SUBC/S280/TR8 be used as a cost-reduction alternative?

A: 19-215SUBC/S280/TR8 operates at 2mA test current with 20mcd luminous intensity, representing an 8-fold reduction in brightness compared to the original 160mcd specification. This part is suitable only for applications with relaxed brightness requirements or where power consumption is the primary design constraint. Standard indication applications require the higher brightness alternatives.

Q: What packaging format should be selected for production?

A: APT1608VBC/D and APT1608QBC/G are supplied in Tape & Reel (TR) format, supporting automated pick-and-place assembly. EAST16086BA0 is also available in Tape & Reel format. Original APT1608PBC/Z was supplied in bulk packaging. Tape & Reel format is recommended for production volumes to optimize assembly efficiency and reduce handling costs.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts (APT1608VBC/D, APT1608QBC/G, EAST16086BA0, and 19-215SUBC/S280/TR8) are ROHS3 compliant. Compliance status matches the original APT1608PBC/Z specification, ensuring regulatory alignment for end-product certification.

Q: Which substitute offers the best supply chain security?

A: APT1608QBC/G provides the highest inventory availability (84,168 pcs), followed by APT1608VBC/D (43,551 pcs). For applications requiring long-term supply assurance, APT1608QBC/G is the optimal selection. EAST16086BA0 (950 pcs) and 19-215SUBC/S280/TR8 (21,620 pcs) offer lower inventory levels and require supply verification for high-volume production.
