Engineering Selection Recommendations

Direct Substitutes (Identical Electrical Characteristics):

SSL-LX5093SGC/B from Lumex Opto/Components Inc. matches the WP7113GC in forward voltage (2.2V) and test current (20mA). This part maintains identical mechanical form factor and height specification. Higher millicandela rating (300mcd vs 80mcd) and wider viewing angle (30° vs 20°) represent performance enhancements suitable for applications requiring increased visibility. ROHS3 compliance and unlimited MSL rating are equivalent.

Compatible Substitutes (Electrical Tolerance Range):

LTL-4238, LTL2R3KGKNN, and LTL2P3KGKNN from Lite-On Inc. operate at 2.1V forward voltage, within 0.1V tolerance of the main part. All three maintain T-1 3/4 form factor and through-hole radial mounting. Test current specifications (10mA to 20mA) and wavelength-peak values (565nm to 575nm) fall within acceptable indicator LED operating ranges. ROHS3 compliance confirmed for all three parts.

5219201F from Dialight operates at 2.1V with 60mcd brightness, meeting minimum brightness threshold. T-1 3/4 form factor confirmed. Designed for incandescent lamp replacement applications with multiple midget flange base compatibility.

Compliance Status:

All substitute parts maintain ROHS3 compliance and MSL 1 (unlimited) rating. REACH status varies: SSL-LX5093SGC/B and 5219201/5219201F are REACH Unaffected; LTL2R3KGKNN is REACH Affected. Selection should account for end-application regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can SSL-LX5093SGC/B replace WP7113GC in all applications?

A: SSL-LX5093SGC/B is mechanically and electrically compatible. Forward voltage (2.2V) and test current (20mA) are identical. The higher brightness output (300mcd vs 80mcd) and wider viewing angle (30° vs 20°) represent performance improvements. Circuit current-limiting resistor values may require adjustment if brightness consistency is critical to application function.

Q: What is the difference between LTL2R3KGKNN and LTL2P3KGKNN?

A: Both parts are Lite-On Inc. T-1 3/4 green LEDs with 2.1V forward voltage and 20mA test current. LTL2P3KGKNN provides higher brightness (980mcd vs 680mcd) with narrower viewing angle (22° vs 30°). LTL2R3KGKNN offers wider viewing angle with lower brightness. Selection depends on application visibility requirements and spatial constraints.

Q: Are there inventory considerations for substitute selection?

A: Inventory levels vary significantly. LTL2P3KGKNN has highest availability (22842 pcs), followed by LTL-4238 (11122 pcs). WP7113GC (2278 pcs) and SSL-LX5093SGC/B (5189 pcs) have moderate stock. 5219201 (939 pcs) and LTL2R3KGKNN (671 pcs) have limited availability. Supply chain planning should account for these variations.

Q: What is the significance of forward voltage tolerance (2.1V vs 2.2V)?

A: The 0.1V difference is within standard LED manufacturing tolerance. Circuit design typically incorporates current-limiting resistors that accommodate this variation. At 20mA test current, the voltage difference represents minimal power dissipation change. Both voltage levels are acceptable for indicator applications.

Q: How do wavelength differences (565nm vs 572nm vs 569nm) affect visual appearance?

A: All identified wavelengths fall within the green spectrum perception range. Peak wavelengths of 565nm, 569nm, and 572nm produce visually similar green color appearance to the human eye. Wavelength variation is not a limiting factor for indicator LED substitution in standard applications.

Q: What mounting considerations apply to all substitute parts?

A: All substitute parts use through-hole radial mounting identical to WP7113GC. Physical dimensions (5mm lens diameter, T-1 3/4 form factor) are standardized across all parts. PCB hole spacing and lead diameter compatibility is maintained. No mechanical redesign is required for substitution.

Q: Does REACH status affect part selection?

A: LTL2R3KGKNN is REACH Affected, while other substitutes are REACH Unaffected. Selection depends on end-product regulatory requirements and geographic market destination. Applications subject to REACH compliance should prioritize REACH Unaffected parts (SSL-LX5093SGC/B, LTL-4238, LTL2P3KGKNN, 5219201, 5219201F).
