Parameter Comparison

Engineering Selection Recommendations

All three components—SML-LXR2106SYC-TR, XZMYK74W, and APA2106SYCK—are active production parts with identical electrical and mechanical specifications. Selection between these parts is based on the following engineering factors:

Compliance & Regulatory Status: All three parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity levels (MSL 3, 168 Hours), ensuring equivalent regulatory standing across all substitute options.

Luminous Intensity: The SML-LXR2106SYC-TR and APA2106SYCK both specify 150mcd, while the XZMYK74W specifies 148mcd. This 2mcd difference is within typical manufacturing tolerance for LED indication components and does not affect functional compatibility in standard indication applications.

Packaging Availability: The SML-LXR2106SYC-TR and XZMYK74W are supplied in Tape & Reel (TR) format. The APA2106SYCK is available in Cut Tape (CT) & Digi-Reel® format, providing flexibility for different procurement and assembly workflows.

Inventory Availability: Current stock levels are 853 units (Lumex), 995 units (SunLED), and 2400 units (Kingbright), allowing selection based on supply chain requirements.

Product Status: All three components are active in production, ensuring long-term availability and continued manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can XZMYK74W replace SML-LXR2106SYC-TR in existing designs?

A: Yes. The XZMYK74W maintains identical electrical parameters (2V forward voltage, 20mA test current, 590nm peak wavelength), mechanical dimensions (2.10mm x 1.00mm x 0.60mm height), mounting type (surface mount right angle), and package configuration (2-SMD, no lead). The 2mcd difference in luminous intensity (148mcd vs. 150mcd) is within standard manufacturing tolerance for LED indication components.

Q: What is the difference between the packaging options?

A: The SML-LXR2106SYC-TR and XZMYK74W are supplied in Tape & Reel (TR) format, suitable for high-volume automated assembly. The APA2106SYCK is available in Cut Tape (CT) & Digi-Reel® format, which accommodates both manual and automated pick-and-place operations with different reel specifications.

Q: Are all three parts RoHS3 compliant?

A: Yes. All three components—SML-LXR2106SYC-TR, XZMYK74W, and APA2106SYCK—are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory requirements.

Q: Do these parts have the same moisture sensitivity level?

A: Yes. All three components specify MSL 3 (168 Hours), indicating identical moisture sensitivity classification and requiring equivalent storage and handling protocols.

Q: Can I use APA2106SYCK as a direct substitute in a design specified for SML-LXR2106SYC-TR?

A: Yes. The APA2106SYCK is a parametric equivalent with matching electrical specifications (2V, 20mA, 590nm, 150mcd), identical mechanical dimensions and mounting configuration, and equivalent compliance status. The only difference is the packaging format (Cut Tape & Digi-Reel® vs. Tape & Reel), which does not affect component performance or PCB assembly compatibility.

Q: What determines whether a part qualifies as a substitute?

A: Substitution is determined by matching electrical parameters (forward voltage, test current, wavelength, viewing angle), mechanical parameters (dimensions, mounting type, lens configuration), and regulatory compliance (RoHS status, moisture sensitivity level). All three listed parts meet these criteria.

Q: Is the 2mcd difference between XZMYK74W (148mcd) and the other parts (150mcd) significant?

A: No. The 2mcd difference represents approximately 1.3% variation and is within standard manufacturing tolerance for LED indication components. Both values are suitable for standard indication applications where precise luminous intensity is not a critical design parameter.
