7017X15 Green LED 0603 SMD Equivalent & Substitute Parts

Part Overview

The 7017X15 is a green diffused LED manufactured by Visual Communications Company (VCC) in 0603 (1608 Metric) surface mount package. This component is classified as Obsolete product status, indicating it is no longer in active production. The part provides green LED indication functionality with a forward voltage of 2.1V and brightness rating of 2.4mcd at 20mA test current.

Due to obsolescence, identifying functionally compatible substitute parts is necessary for ongoing design support, production continuity, and component sourcing. Substitute parts must maintain compatibility with existing PCB layouts, electrical specifications, and application requirements.

Substitute Part Grouping Explanation

Substitute parts for the 7017X15 are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

Package / Case: 0603 (1608 Metric) surface mount
Mounting Type: Surface Mount
Color: Green (primary criterion for optical function)
Lens Transparency: Diffused (optical characteristic match)
Voltage - Forward (Vf): 2.1V nominal (circuit design compatibility)
Current - Test: 20mA (standard test condition)
Size / Dimension: 1.60mm L x 0.80mm W (PCB layout compatibility)
RoHS Status: ROHS3 Compliant (regulatory requirement)

Substitution Logic: Substitute parts are grouped into two categories based on adherence to these criteria:

Category A - Direct Substitutes (Diffused Green LEDs): Parts that maintain green color, diffused lens transparency, 2.1V forward voltage, and 0603 package. These parts are electrically and mechanically interchangeable with the 7017X15 in standard applications.

Category B - Functional Alternatives (Different Optical Properties): Parts that maintain 0603 package, surface mount configuration, and compatible voltage range but differ in color, lens transparency, or brightness. These parts require application-level evaluation for suitability.

Engineering Selection Recommendations

Recommended Primary Substitute: SML-D13FWT86 (Rohm Semiconductor)

The SML-D13FWT86 is the optimal substitute for the 7017X15 based on the following engineering criteria:

Product Status: Active production status ensures long-term availability and supply chain continuity
Electrical Compatibility: Identical forward voltage (2.1V) and test current (20mA) enable direct circuit integration without redesign
Optical Compatibility: Green color with diffused lens transparency maintains the intended visual indication function
Package Compatibility: 0603 (1608 Metric) surface mount package with matching footprint dimensions (1.60mm L x 0.80mm W)
Regulatory Compliance: ROHS3 compliant with MSL 3 rating matching the original part
Brightness Consideration: 22mcd rating provides increased brightness (9.2x higher) compared to 2.4mcd original, suitable for improved visibility in standard indication applications

Secondary Substitute: SML-D12FWT86 (Rohm Semiconductor)

The SML-D12FWT86 provides an alternative with the following characteristics:

Product Status: Not For New Designs classification indicates limited future availability
Electrical Compatibility: Forward voltage of 2.2V is within acceptable tolerance for most circuit designs (0.1V variance)
Optical Compatibility: Green diffused lens maintains visual function
Package Compatibility: Identical 0603 package and footprint
Brightness: 18mcd rating provides 7.5x brightness increase over original

Alternative Consideration: 19-218/GHC-YR1S2M/3T (Everlight Electronics)

This part is suitable only for applications where optical properties can be modified:

Electrical Incompatibility: Forward voltage of 3.35V requires circuit redesign and is not a direct substitute
Optical Difference: Clear lens transparency differs from diffused specification
Brightness: 198.5mcd is significantly higher and may not be appropriate for all applications
Package Variance: Width dimension of 1.00mm differs from standard 0.80mm, requiring PCB layout verification

Not Recommended for Substitution:

SML-D13MWT86A: Yellow-Green color differs from green specification; intended for different visual indication applications
SML-D15UWT86: Red color is functionally incompatible with green LED indication requirements

Frequently Asked Questions (FAQ)

Q1: Can the SML-D13FWT86 be used as a direct replacement for the 7017X15 without circuit modification?

A: Yes. The SML-D13FWT86 maintains identical forward voltage (2.1V), test current (20mA), and 0603 package configuration. No circuit redesign is required. The increased brightness (22mcd vs. 2.4mcd) is a functional improvement for indication applications and does not create compatibility issues.

Q2: Why is the 19-218/GHC-YR1S2M/3T not recommended as a direct substitute despite being a green LED in 0603 package?

A: The 19-218/GHC-YR1S2M/3T has a forward voltage of 3.35V compared to the 7017X15 specification of 2.1V. This 1.25V difference requires circuit redesign to adjust current-limiting resistor values and may affect power consumption. Additionally, the clear lens transparency differs from the diffused specification, altering the visual appearance of the indication.

Q3: What is the significance of the "Not For New Designs" status on the SML-D12FWT86?

A: This status indicates that Rohm Semiconductor is not recommending this part for new product designs, though it remains available for existing applications. While technically compatible with the 7017X15, the SML-D13FWT86 is the preferred choice for new designs due to its Active product status and longer projected availability.

Q4: Are there any PCB layout considerations when substituting the 7017X15 with recommended alternatives?

A: The recommended substitutes (SML-D13FWT86 and SML-D12FWT86) maintain identical footprint dimensions (1.60mm L x 0.80mm W) and height specifications within acceptable tolerance. The 19-218/GHC-YR1S2M/3T has a width of 1.00mm versus the standard 0.80mm, requiring verification that the PCB pad layout can accommodate this variance.

Q5: How does the increased brightness of substitute parts affect application performance?

A: The SML-D13FWT86 (22mcd) and SML-D12FWT86 (18mcd) provide 9.2x and 7.5x brightness increases respectively compared to the 2.4mcd original. In standard indication applications, this improvement enhances visibility without creating functional problems. However, in applications with brightness-sensitive requirements or where the original low brightness was intentional, circuit modifications (such as reduced current or series resistor adjustment) may be necessary.

Q6: What compliance certifications should be verified when selecting a substitute?

A: All recommended substitutes maintain ROHS3 compliance and MSL 3 (168 Hours) moisture sensitivity ratings matching the original 7017X15. These certifications ensure regulatory compliance for consumer and industrial applications. The 19-218/GHC-YR1S2M/3T does not specify RoHS status in the provided data and should be verified with the manufacturer before use in regulated applications.

Q7: Can the SML-D15UWT86 (red LED) be used if the application allows color substitution?

A: The SML-D15UWT86 is not recommended for green LED indication applications. While it maintains 0603 package compatibility and diffused lens transparency, the red color (620nm wavelength) is functionally incompatible with green indication requirements. Color substitution fundamentally changes the application function and should not be considered a technical equivalent.
