Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the APA1606PBC/A is determined by strict alignment of the following parameters:

Critical Compatibility Parameters:

• Mounting Type: Surface Mount, Right Angle
• Package / Case: 2-SMD, No Lead
• Physical Dimensions: 1.60mm L x 1.20mm W, 0.60mm Max Height
• Current - Test: 20mA
• Viewing Angle: 110°
• Color: Blue
• RoHS Status: ROHS3 Compliant
• MSL Rating: 3 (168 Hours)

Allowable Variation Parameters:

• Voltage - Forward (Vf): ±0.1V tolerance acceptable
• Millicandela Rating: ±20% brightness variation acceptable
• Wavelength - Dominant: ±5nm variation acceptable
• Wavelength - Peak: ±8nm variation acceptable

Substitute parts must maintain identical mounting configuration, package type, and physical footprint. Electrical parameters including forward voltage, test current, and viewing angle must remain within specified tolerances to ensure circuit compatibility and optical performance equivalence.

Engineering Selection Recommendations

APA1606QBC/D (Kingbright - MFR Recommended Substitute)

The APA1606QBC/D is the manufacturer-recommended substitute for the obsolete APA1606PBC/A. Both components share identical physical dimensions, mounting configuration, and package specifications. The APA1606QBC/D maintains active product status with full ROHS3 compliance and equivalent MSL rating. Forward voltage increases from 3.2V to 3.3V (0.1V differential), and millicandela rating increases from 60mcd to 80mcd. Wavelength-dominant shifts from 470nm to 465nm (5nm variation). These parameter variations remain within acceptable engineering tolerances for LED indication applications. The component is available in Cut Tape and Digi-Reel packaging with 2280 units in stock.

XZCBD87W (SunLED - Similar Substitute)

The XZCBD87W from SunLED provides an alternative substitute option with active product status and full compliance certifications. Physical dimensions and mounting type are identical to the main part. Forward voltage matches the APA1606QBC/D at 3.3V. Millicandela rating of 79mcd aligns closely with the APA1606QBC/D. Wavelength-dominant and peak values match the APA1606QBC/D specifications. The component is supplied in Tape & Reel packaging with 2386 units in stock. Cross-manufacturer substitution introduces supply chain diversification while maintaining electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Why is the APA1606PBC/A classified as obsolete?

A: The APA1606PBC/A has reached end-of-life status with the manufacturer. Kingbright has transitioned production to the active APA1606QBC/D variant, which incorporates improved specifications while maintaining physical and functional compatibility.

Q: Can the APA1606QBC/D directly replace the APA1606PBC/A in existing circuit designs?

A: Yes. Both components share identical mounting type (Surface Mount, Right Angle), package configuration (2-SMD, No Lead), physical dimensions (1.60mm L x 1.20mm W x 0.60mm H), and test current (20mA). Forward voltage increases by 0.1V (3.2V to 3.3V), which is within standard circuit tolerance for LED indication applications. Brightness increases from 60mcd to 80mcd, providing enhanced visibility without circuit modification.

Q: What are the key differences between the APA1606QBC/D and XZCBD87W?

A: Both substitutes maintain identical mounting configuration, package type, and physical dimensions. The primary difference is manufacturer: APA1606QBC/D is Kingbright (same as the main part), while XZCBD87W is SunLED. Electrical specifications are nearly identical, with millicandela ratings of 80mcd and 79mcd respectively. Lens size differs slightly: APA1606QBC/D uses 1.20mm x 0.60mm, while XZCBD87W uses 1.10mm x 0.80mm. Both maintain 110° viewing angle and 3.3V forward voltage.

Q: Are there packaging differences between substitute options?

A: Yes. The APA1606QBC/D is available in Cut Tape (CT) and Digi-Reel packaging. The XZCBD87W is supplied in Tape & Reel (TR) format. Both packaging types are standard for surface mount component distribution and are compatible with automated assembly equipment.

Q: Do both substitutes meet the same compliance requirements as the original part?

A: Yes. Both APA1606QBC/D and XZCBD87W are ROHS3 compliant, REACH unaffected, and carry MSL rating 3 (168 Hours), matching the original APA1606PBC/A specifications. Both are classified under ECCN EAR99 and HTSUS 8541.41.0000.

Q: What is the wavelength difference between the main part and substitutes?

A: The APA1606PBC/A has a dominant wavelength of 470nm (peak 468nm). Both substitutes shift to 465nm dominant wavelength (peak 460nm), representing a 5nm reduction. This shift remains within acceptable blue LED specification ranges and does not affect visual indication performance in standard applications.

Q: Can I use XZCBD87W if APA1606QBC/D is unavailable?

A: Yes. The XZCBD87W provides functional equivalence with identical mounting, package, and electrical test parameters. Cross-manufacturer substitution is valid when primary options are unavailable, provided all critical parameters remain within specified tolerances.
