Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7017X5 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Package / Case: 0603 (1608 Metric) surface mount form factor
• Mounting Type: Surface Mount
• Voltage - Forward (Vf): 2.1V ±0.2V tolerance range
• Current - Test: 20mA standard test condition
• Color: Green spectrum (560–569nm peak wavelength acceptable)
• Lens Transparency: Diffused preferred; clear acceptable with design verification
• RoHS Compliance: ROHS3 Compliant required

Secondary Compatibility Considerations:

• Millicandela rating variance (6.4mcd baseline; higher brightness acceptable)
• Viewing angle (70° baseline; wider angles acceptable)
• Height and dimensional fit within PCB assembly constraints
• Moisture Sensitivity Level (MSL 1–3 acceptable for standard storage)

The substitute parts listed below meet the primary criteria and are suitable for direct replacement in applications where the 7017X5 was originally specified.

Parameter Comparison

Engineering Selection Recommendations

Tier 1 - Direct Replacement (Highest Compatibility):

LTST-C191GKT (Lite-On Inc.) is the primary recommended substitute. This part maintains identical forward voltage (2.1V), package form factor (0603), and test current (20mA) as the 7017X5. The LTST-C191GKT is in Active product status with ROHS3 compliance and offers superior viewing angle (130° vs. 70°) and comparable brightness (12mcd vs. 6.4mcd). Height is reduced to 0.55mm, providing improved PCB assembly clearance. Lens transparency differs (clear vs. diffused); applications requiring diffused optics require optical performance verification.

SML-D13FWT86 (Rohm Semiconductor) provides direct electrical compatibility with 2.1V forward voltage and maintains diffused lens transparency matching the original design intent. This part is in Active status with ROHS3 compliance. Brightness is elevated to 22mcd, suitable for applications tolerating increased luminous intensity. Height specification (0.65mm) remains within typical PCB assembly tolerances.

Tier 2 - Conditional Replacement (Design Verification Required):

SML-D12FWT86 (Rohm Semiconductor) offers diffused lens transparency and comparable brightness (18mcd). Forward voltage is slightly elevated at 2.2V; circuit designs with tight voltage regulation require verification. Product status is "Not For New Designs," limiting suitability for new development but acceptable for legacy system maintenance.

19-218/GHC-YR1S2M/3T (Everlight Electronics) is not recommended as a direct substitute. Forward voltage is significantly elevated at 3.35V, requiring circuit redesign. Brightness is substantially higher (198.5mcd), introducing optical performance deviation. Lens transparency is clear rather than diffused. This part is suitable only for applications where optical and electrical characteristics differ from the original specification.

SML-D13MWT86A (Rohm Semiconductor) is not recommended for green LED applications. This part is specified as Yellow-Green (571nm wavelength), introducing color shift incompatible with green indication requirements.

Compliance & Supply Chain Considerations:

All Tier 1 and Tier 2 recommended substitutes maintain ROHS3 compliance, ensuring regulatory alignment with the original 7017X5. Moisture Sensitivity Level increases from MSL 1 to MSL 2A or MSL 3 in substitute parts; standard dry storage and handling procedures mitigate risk. Active product status of LTST-C191GKT and SML-D13FWT86 ensures long-term supply availability and design continuity.

Frequently Asked Questions (FAQ)

Q1: Can LTST-C191GKT replace 7017X5 in all applications?

LTST-C191GKT is electrically and mechanically compatible (2.1V, 20mA, 0603 package). The primary difference is lens transparency: LTST-C191GKT is clear versus 7017X5 diffused. Applications requiring diffused light distribution must evaluate optical performance. Clear lenses concentrate light intensity in a narrower beam; diffused lenses scatter light over a wider area. Verify that the application's optical requirements are satisfied before substitution.

Q2: Why is 19-218/GHC-YR1S2M/3T listed as a substitute if it has 3.35V forward voltage?

19-218/GHC-YR1S2M/3T is listed in the original substitute data but is not recommended for direct replacement. The 3.35V forward voltage requires circuit redesign and is incompatible with designs optimized for 2.1V operation. This part is suitable only for applications where electrical characteristics differ from the original specification.

Q3: What is the impact of increased millicandela rating in substitute parts?

Substitute parts such as SML-D13FWT86 (22mcd) and SML-D13MWT86A (45mcd) deliver higher brightness than the original 7017X5 (6.4mcd). In indication applications, increased brightness is generally acceptable and improves visibility. However, applications with strict brightness specifications or power-limited designs may require current limiting resistor adjustment to maintain original luminous intensity.

Q4: Are there height differences that affect PCB assembly?

Yes. The 7017X5 has a maximum height of 0.71mm. Substitute parts range from 0.40mm (19-218/GHC-YR1S2M/3T) to 0.65mm (SML-D13FWT86, SML-D12FWT86, SML-D13MWT86A). Reduced height improves PCB assembly clearance and is generally beneficial. Verify that PCB solder pad design and component placement accommodate the substitute part's height specification.

Q5: What is the difference between diffused and clear lens transparency?

Diffused lenses scatter light uniformly over a wide viewing angle, producing soft, dispersed illumination suitable for general indication. Clear lenses concentrate light intensity, producing brighter, more directional illumination with narrower viewing angle. The 7017X5 uses diffused optics; substitutes with clear lenses (LTST-C191GKT, 19-218/GHC-YR1S2M/3T) alter optical characteristics. Select based on application requirements.

Q6: Does Moisture Sensitivity Level (MSL) affect component reliability?

The 7017X5 is MSL 1 (unlimited shelf life). Substitute parts are MSL 2A or MSL 3, requiring controlled storage (4 weeks to 168 hours at specified humidity). Standard manufacturing practices with dry storage and desiccant packaging mitigate MSL risk. No reliability impact occurs if standard handling procedures are followed.

Q7: Are all substitute parts ROHS3 compliant?

LTST-C191GKT, SML-D13FWT86, SML-D12FWT86, and SML-D13MWT86A are ROHS3 compliant. 19-218/GHC-YR1S2M/3T RoHS status is not specified in available data. Verify RoHS compliance documentation for regulatory applications.

Q8: Which substitute is recommended for new designs?

LTST-C191GKT (Lite-On Inc.) is the primary recommendation for new designs. It is in Active product status, ROHS3 compliant, electrically compatible (2.1V, 20mA), and offers superior viewing angle (130°). SML-D13FWT86 (Rohm Semiconductor) is the secondary recommendation, maintaining diffused lens transparency and Active product status. SML-D12FWT86 is not recommended for new designs due to "Not For New Designs" status.
