Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SML-D14DWT86C is determined by strict equivalence across the following critical parameters:

• Package / Case: 0603 (1608 Metric) — ensures mechanical and thermal compatibility on PCB layouts
• Color: Orange — maintains visual indication consistency
• Wavelength - Dominant: 605nm — preserves optical performance specification
• Voltage - Forward (Vf) (Typ): 2V — ensures circuit compatibility without redesign
• Current - Test: 20mA — maintains operational envelope
• Mounting Type: Surface Mount — confirms assembly process compatibility
• Grade: Automotive — required for automotive application environments
• Qualification: AEC-Q102 — mandatory for automotive reliability standards
• RoHS Status: ROHS3 Compliant — ensures regulatory compliance

The SML-D15DWT86C qualifies as a parametric equivalent substitute based on matching all critical parameters above. Brightness rating variation (224mcd vs. 200mcd) falls within acceptable tolerance for indication-class LEDs and does not disqualify substitution when brightness headroom is acceptable in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

Both the SML-D14DWT86C and SML-D15DWT86C maintain active product status with identical automotive-grade certifications and ROHS3 compliance. Selection between these parts is based on application brightness requirements. The SML-D14DWT86C provides 200mcd output, while the SML-D15DWT86C delivers 224mcd. For applications where the original 200mcd specification is a design requirement, the SML-D14DWT86C is the primary choice. For applications where increased brightness is acceptable or beneficial, the SML-D15DWT86C offers higher luminous intensity within the same electrical and mechanical envelope. Both parts satisfy AEC-Q102 automotive qualification requirements and are suitable for direct substitution in automotive indication circuits.

Frequently Asked Questions (FAQ)

Q: Can the SML-D15DWT86C replace the SML-D14DWT86C in an existing design?

A: Yes, provided the application circuit can accommodate the higher brightness output (224mcd vs. 200mcd). All electrical parameters, package dimensions, and automotive certifications are identical. No PCB layout or schematic modifications are required.

Q: Are there any thermal or reliability differences between these parts?

A: No thermal or reliability differences exist. Both parts share identical package dimensions (1.60mm L x 0.80mm W, 0.65mm max height), moisture sensitivity level (MSL 3), and AEC-Q102 qualification status.

Q: What is the significance of the 605nm wavelength specification?

A: The 605nm dominant wavelength defines the orange color perception and optical performance of the LED. Both substitute parts maintain this specification, ensuring consistent visual indication across the product line.

Q: Are these parts suitable for automotive applications?

A: Yes. Both parts carry automotive-grade classification and AEC-Q102 qualification, meeting automotive reliability and environmental stress testing requirements.

Q: What does ROHS3 compliance mean for these parts?

A: ROHS3 compliance indicates the parts are manufactured without restricted substances (lead, cadmium, mercury, hexavalent chromium, PBBs, PBDEs) as defined by the Restriction of Hazardous Substances Directive, meeting environmental and regulatory standards for automotive and consumer applications.

Q: Can these parts be used interchangeably in high-volume production?

A: Yes, both parts are available in Tape & Reel (TR) packaging suitable for automated assembly. The SML-D15DWT86C currently shows higher inventory availability (8679 pcs vs. 2314 pcs), which may influence supply chain decisions for high-volume production runs.
