LED YELLOW DIFFUSED 0603 SMD 7017X13 Equivalent & Substitute Parts

Part Overview

The 7017X13 is a yellow diffused LED in 0603 (1608 Metric) surface mount package manufactured by Visual Communications Company (VCC). This component is classified as Obsolete and is no longer in active production. The part delivers 3.4 millicandela at 20mA test current with a forward voltage of 2.2V and a dominant wavelength of 580nm. Due to its obsolete status, identifying functionally equivalent substitute components is essential for ongoing design support, maintenance, and new production requirements where yellow LED indication functionality is required in the 0603 form factor.

Engineering Selection Recommendations

Primary Recommendation for New Designs:

For new product designs and production requiring yellow LED indication in 0603 surface mount format, SML-D12Y3WT86 (Rohm Semiconductor) is the preferred substitute. This part maintains exact electrical compatibility with the 7017X13 (2.2V forward voltage, 20mA test current) while offering active product status and full ROHS3 compliance. The 40mcd brightness rating provides adequate indication visibility while remaining within standard LED indication specifications.

Alternative for High-Brightness Applications:

SML-D13WWT86A (Rohm Semiconductor) provides significantly higher brightness (112mcd) at compatible electrical parameters (2.1V forward voltage, 20mA test current). This part is suitable for applications requiring enhanced visibility or longer viewing distances. Active product status and ROHS3 compliance are confirmed.

Consideration for Existing Inventory Management:

SML-511WWT86 (Rohm Semiconductor) offers functional equivalence with 40mcd brightness and 2.0V forward voltage. However, this part carries "Not For New Designs" status, making it suitable only for maintenance of existing products or legacy system support where supply continuity is the primary objective.

Optical Characteristic Trade-off:

19-219/Y5C-AM1N2VY/3T (Everlight Electronics) features clear lens transparency versus the diffused lens of the original 7017X13. Clear lens designs produce more directional light output with higher peak brightness (31.5mcd) but narrower effective viewing angle. This part is acceptable only in applications where directional indication is preferred over diffused light distribution. Forward voltage is lower (1.95V), requiring circuit verification for compatibility.

Brightness Consideration:

All recommended substitutes exceed the original 3.4mcd specification. In indication-only applications, higher brightness is acceptable and does not create functional incompatibility. Circuit designers should verify that increased brightness does not create visual glare or exceed application-specific requirements.

Compliance and Supply Chain:

All recommended active-status parts (SML-D12Y3WT86, SML-D13WWT86A, 19-219/Y5C-AM1N2VY/3T, APT1608PYW) carry ROHS3 compliance certification, meeting modern regulatory and supply chain requirements. MSL 3 (168 Hours) rating is standard for these components and compatible with typical manufacturing environments.

Frequently Asked Questions (FAQ)

Q1: Can I use an orange LED (such as SML-511DWT86) as a substitute for the yellow 7017X13?

A: No. Color substitution is not permitted. Orange LEDs (605–606nm wavelength) and yellow LEDs (580–591nm wavelength) produce visually distinct light output. Applications requiring yellow indication must use yellow-colored LEDs only. Orange substitutes will alter the visual indication and may violate design specifications or regulatory requirements.

Q2: The 7017X13 has a 70° viewing angle, but some substitutes offer 120–130°. Is this acceptable?

A: Yes. Wider viewing angles are acceptable in substitution. A 120° or 130° viewing angle provides equal or superior light distribution compared to the original 70° specification. This is beneficial in applications where the LED must be visible from multiple angles. Narrower viewing angles would not be acceptable as they restrict visibility.

Q3: Why do substitute parts have higher millicandela ratings (8–112mcd) compared to the original 3.4mcd?

A: Higher brightness is a result of improved LED manufacturing technology and does not create incompatibility. In indication applications, increased brightness improves visibility and is generally advantageous. Circuit designers should verify that the higher brightness does not create unwanted visual effects (glare, excessive power consumption) in the specific application context. If brightness reduction is required, series resistor values can be adjusted.

Q4: The 19-219/Y5C-AM1N2VY/3T has a clear lens instead of diffused. What is the functional difference?

A: Clear lens LEDs produce more concentrated, directional light output with higher peak brightness in the forward direction. Diffused lens LEDs scatter light more uniformly across a wider area, producing softer, more distributed illumination. For general indication purposes, both are acceptable. Choose clear lens for directional applications (e.g., status indicators viewed from specific angles) and diffused lens for omnidirectional visibility requirements.

Q5: Can I substitute the 7017X13 with a 0805 package LED to get higher brightness?

A: No. Package form factor is not substitutable. The 0603 (1608 Metric) package is a specific mechanical and electrical standard. Substituting with 0805 or other package sizes will not fit the PCB footprint and requires complete circuit redesign. Only 0603 surface mount packages are acceptable substitutes.

Q6: What is the difference between "Active" and "Not For New Designs" product status?

A: "Active" status indicates the manufacturer continues production and supports the part for new designs. "Not For New Designs" indicates the part is in production for existing customer support only and may be discontinued. For new product development, select only "Active" status parts (SML-D12Y3WT86, SML-D13WWT86A, 19-219/Y5C-AM1N2VY/3T, APT1608PYW). For legacy product maintenance, "Not For New Designs" parts (SML-511WWT86) are acceptable if supply is available.

Q7: The 7017X13 has MSL 1 (Unlimited), but substitutes have MSL 3 (168 Hours). Does this affect manufacturing?

A: MSL 3 (168 Hours) is standard for modern LED components and is compatible with typical surface mount assembly processes. MSL 1 (Unlimited) indicates the original part had no moisture sensitivity restrictions. MSL 3 requires that components be stored in controlled humidity conditions and used within 168 hours of package opening. This is a standard industry practice and does not create functional incompatibility if proper handling procedures are followed.

Q8: Can I use SML-D11YWT86 (1.85V, 2mA test current) as a substitute?

A: SML-D11YWT86 is not recommended as a primary substitute. While it meets color and package requirements, the 1.85V forward voltage and 2mA test current differ significantly from the 7017X13 specification (2.2V, 20mA). This part is designed for low-power applications and would require circuit redesign. Use SML-D12Y3WT86 or SML-D13WWT86A for direct electrical compatibility.

Q9: What is the difference between wavelength-dominant and wavelength-peak specifications?

A: Wavelength-dominant is the primary color wavelength perceived by the human eye. Wavelength-peak is the precise wavelength at maximum spectral output. Both specifications fall within the yellow range (580–591nm) for all recommended substitutes. The slight variations do not create visible color differences in indication applications.

Q10: Are all recommended substitutes available in Tape & Reel (TR) packaging?

A: Yes. All substitute parts listed are available in Tape & Reel packaging, which is standard for surface mount component supply. The 7017X13 original part was also supplied in this format. Tape & Reel packaging is compatible with automated pick-and-place assembly equipment.
