Parameter Comparison

Engineering Selection Recommendations

Lite-On Inc. LTL2P3KGKNN and LTL2R3KGKNN

These parts provide the closest electrical and mechanical alignment with the WP7113CGCK. Both operate at 2.1V forward voltage with 20mA test current, matching the primary part specifications. The LTL2P3KGKNN delivers 980mcd brightness with a 22° viewing angle, while the LTL2R3KGKNN provides 680mcd with a 30° viewing angle. Both maintain ROHS3 compliance and MSL Level 1 rating. Height specifications (8.70mm) remain within acceptable mechanical tolerance for through-hole mounting applications.

Lite-On Inc. LTL-4238

This part operates at 2.1V forward voltage with clear lens and T-1 3/4 form factor. The 10mA test current and 90mcd brightness represent reduced electrical and optical performance compared to the primary part. This configuration is suitable for applications where lower brightness is acceptable or preferred.

Lumex Opto/Components Inc. SSL-LX5093 Series (SGC/B, XGC, XPGC)

These parts operate at 2.2V forward voltage, representing a 0.1V increase from the primary specification. All three variants maintain 20mA test current and clear lens transparency. The SSL-LX5093SGC/B (300mcd, 30° viewing angle) and SSL-LX5093XGC (250mcd, 20° viewing angle) provide moderate brightness levels. The SSL-LX5093XPGC (45mcd, 20° viewing angle) is suitable for low-brightness indicator applications. All maintain ROHS3 compliance and MSL Level 1 rating.

Dialight 5219201 and 5219201F

The 5219201 is a generic 5mm through-hole LED with limited parameter specification. The 5219201F is configured as a lamp replacement with 60mcd brightness and 2.1V forward voltage, suitable for incandescent replacement applications. Both maintain ROHS3 compliance.

All listed substitute parts are Active product status with ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility with the primary component.

Frequently Asked Questions (FAQ)

Q: Can the LTL2P3KGKNN replace the WP7113CGCK in all applications?

A: The LTL2P3KGKNN shares identical forward voltage (2.1V), test current (20mA), and mounting specifications (through-hole, T-1 3/4, radial package). The primary difference is brightness: 980mcd versus 700mcd. Substitution is valid when the application tolerates increased brightness or when brightness reduction is not a design constraint.

Q: What is the significance of the 0.1V difference in forward voltage between the WP7113CGCK (2.1V) and Lumex SSL-LX5093 series (2.2V)?

A: The 0.1V difference represents a 4.8% increase in forward voltage. This affects circuit design calculations for current-limiting resistors. Applications using fixed resistor networks must recalculate resistor values to maintain 20mA test current. The difference is within typical LED manufacturing tolerance ranges but requires verification in voltage-sensitive applications.

Q: Are all substitute parts mechanically compatible with the WP7113CGCK footprint?

A: All substitute parts share the T-1 3/4 (5mm) through-hole radial package configuration. Height specifications range from 8.60mm to 8.70mm, representing a 0.10mm maximum variation. This tolerance is acceptable for standard through-hole PCB mounting. Physical verification is recommended for applications with height-constrained layouts.

Q: Which substitute part provides the closest brightness match to the WP7113CGCK?

A: The LTL2R3KGKNN (680mcd) provides the closest brightness match to the WP7113CGCK (700mcd), with a 2.9% difference. The LTL2P3KGKNN (980mcd) offers higher brightness, while the Lumex SSL-LX5093SGC/B (300mcd) and LTL-4238 (90mcd) provide significantly lower brightness options.

Q: What is the viewing angle significance when selecting a substitute?

A: Viewing angle determines the cone of light distribution from the LED. The WP7113CGCK has a 20° viewing angle. Substitute parts range from 16° to 30°. Narrower angles (16°-20°) concentrate light in a tighter cone, suitable for direct line-of-sight applications. Wider angles (22°-30°) distribute light across a broader area, suitable for applications requiring visibility from multiple viewing positions.

Q: Are all substitute parts compliant with the same regulatory standards as the WP7113CGCK?

A: All listed substitute parts maintain ROHS3 compliance, MSL Level 1 (Unlimited) rating, and Active product status. The LTL2R3KGKNN has REACH Affected status, while the WP7113CGCK and most other substitutes have REACH Unaffected status. Applications subject to REACH regulations should verify compliance requirements before selecting the LTL2R3KGKNN.

Q: Can the Dialight 5219201F be used as a direct replacement for the WP7113CGCK?

A: The 5219201F is configured as an incandescent lamp replacement with 60mcd brightness and 2.1V forward voltage. While it shares the same forward voltage and T-1 3/4 form factor, the significantly lower brightness (60mcd versus 700mcd) limits its application scope. Substitution is valid only when the application requires reduced brightness or lamp replacement functionality.

Q: What parameters should be verified before implementing a substitute part?

A: Critical parameters for verification include: forward voltage (2.1V to 2.2V acceptable range), test current (20mA standard), lens size (5mm, T-1 3/4), mounting type (through-hole, radial), and brightness requirements (700mcd primary specification). Secondary verification includes viewing angle compatibility, wavelength range (565nm to 574nm acceptable), and regulatory compliance status.
