SSL-LX5099GIW Equivalent & Substitute Parts

Part Overview

The SSL-LX5099GIW is an active dual-color LED indicator manufactured by Lumex Opto/Components Inc. This through-hole component combines green and red LED elements in a single T-1 3/4 (5mm) diffused lens package with common cathode configuration. The device is designed for applications requiring simultaneous green and red indication capability with independent color control.

The SSL-LX5099GIW maintains Active product status and is ROHS3 compliant. Substitute parts are identified based on matching electrical characteristics, mechanical form factor, and optical specifications to ensure direct functional equivalence in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SSL-LX5099GIW are classified into two categories based on parametric equivalence:

Parametric Equivalent (Direct Substitute): SSL-LX5099IGW matches all critical electrical and mechanical parameters. This part shares identical forward voltage specifications (2.2V Green, 2V Red), test current (20mA for both colors), millicandela ratings (45mcd Green, 55mcd Red), lens configuration (5mm T-1 3/4 diffused white), viewing angle (60°), and mounting type (through-hole radial 3-lead). The only difference is packaging format (Bulk versus tape-and-reel). This part is functionally interchangeable in all circuit applications.

Similar Equivalent (Functional Substitute): WP59EGW from Kingbright provides functional equivalence with allowable parameter variations. This part maintains identical forward voltage (2.2V Green, 2V Red), test current (20mA), lens style (5mm T-1 3/4 diffused white), viewing angle (60°), and mounting configuration (through-hole radial 3-lead). Variations exist in millicandela ratings (60mcd Green, 40mcd Red versus 45mcd Green, 55mcd Red) and wavelength specifications (568nm/617nm dominant versus 565nm/635nm peak). These variations remain within acceptable tolerance for general indication applications where exact luminous intensity matching is not required.

Parameter Comparison

Engineering Selection Recommendations

SSL-LX5099IGW is the primary substitute for SSL-LX5099GIW. Both parts are manufactured by Lumex Opto/Components Inc., share identical electrical specifications, and maintain Active product status with ROHS3 compliance. Selection between these parts depends solely on packaging requirements: SSL-LX5099GIW is supplied in tape-and-reel format, while SSL-LX5099IGW is supplied in Bulk packaging. Circuit performance and component functionality are identical.

WP59EGW from Kingbright serves as a functional alternative when SSL-LX5099GIW and SSL-LX5099IGW are unavailable. This part maintains electrical compatibility (identical forward voltage and test current) and mechanical form factor (5mm T-1 3/4 through-hole radial 3-lead). The millicandela rating difference (60mcd Green, 40mcd Red versus 45mcd Green, 55mcd Red) represents a 33% increase in green brightness and 27% decrease in red brightness. This variation is acceptable for general indication applications where luminous intensity is not a critical design parameter. WP59EGW is also ROHS3 compliant with MSL 1 rating, ensuring equivalent environmental compliance.

All three parts are suitable for direct PCB mounting in through-hole applications with identical lead spacing and height clearance considerations.

Frequently Asked Questions (FAQ)

Q: Can SSL-LX5099IGW replace SSL-LX5099GIW directly in production?

A: Yes. SSL-LX5099IGW is a parametric equivalent with identical electrical and optical specifications. The only difference is packaging format (Bulk versus tape-and-reel). No circuit modifications are required.

Q: What are the brightness differences between SSL-LX5099GIW and WP59EGW?

A: SSL-LX5099GIW produces 45mcd green and 55mcd red. WP59EGW produces 60mcd green and 40mcd red. The green output is 33% brighter; the red output is 27% dimmer. These differences are visible in side-by-side comparison but acceptable for standard indication applications.

Q: Are all three parts ROHS3 compliant?

A: Yes. SSL-LX5099GIW, SSL-LX5099IGW, and WP59EGW are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the height difference between SSL-LX5099GIW and WP59EGW?

A: SSL-LX5099GIW has a maximum height of 11.00mm. WP59EGW has a maximum height of 11.35mm. This 0.35mm difference is negligible for most PCB applications but should be verified if height clearance is constrained.

Q: Do all three parts use the same lead configuration?

A: Yes. All three parts use radial 3-lead common cathode configuration with identical electrical pinout. They are mechanically and electrically interchangeable in through-hole PCB designs.

Q: Which substitute should I select if brightness is critical?

A: SSL-LX5099IGW maintains identical brightness specifications to SSL-LX5099GIW. WP59EGW has different brightness characteristics and should only be selected if brightness variation is acceptable for the application.
