SSL-LX509F3ID Red LED T-1 3/4 Through Hole Equivalent & Substitute Parts

Part Overview

The SSL-LX509F3ID is an active production red LED indicator manufactured by Lumex Opto/Components Inc., designed for discrete 2V radial through-hole applications. This T-1 3/4 diffused lens LED operates at 20mA test current with a 40 millicandela brightness rating and 635nm peak wavelength. The component is ROHS3 compliant and REACH unaffected, suitable for standard indication circuits requiring red light output at 60° viewing angle. Equivalent substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part number becomes unavailable or when alternative packaging configurations are required.

• Lens Size: 5mm, T-1 3/4
• Voltage - Forward (Vf) Typical: 2V
• Current - Test: 20mA
• Millicandela Rating: 40mcd
• Viewing Angle: 60°
• Mounting Type: Through Hole
• Height Maximum: 8.60mm
• Package / Case: Radial
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Identified Substitutes:

SSL-LX5093LID (Lumex Opto/Components Inc.) – Parametric equivalent with identical electrical and mechanical specifications. Differs only in packaging configuration (Bulk vs. standard packaging) and base product number designation. All critical parameters match the SSL-LX509F3ID.

WP1503ID (Kingbright) – Parametric equivalent meeting all primary matching parameters. Wavelength characteristics differ slightly (dominant wavelength 617nm, peak wavelength 627nm versus SSL-LX509F3ID peak wavelength 635nm), but remain within the red LED spectrum and do not affect functional substitution for standard indication applications. Mechanical and electrical parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

SSL-LX5093LID Selection Criteria: SSL-LX5093LID is a direct parametric equivalent to SSL-LX509F3ID with identical electrical and mechanical specifications. Selection of this substitute is appropriate when bulk packaging is preferred or when SSL-LX509F3ID standard packaging is unavailable. Both parts maintain ROHS3 compliance and MSL 1 rating. No design or circuit modifications are required for substitution.

WP1503ID Selection Criteria: WP1503ID is a parametric equivalent from Kingbright meeting all primary electrical and mechanical requirements. The wavelength difference (627nm peak versus 635nm peak) represents a minor spectral shift within the red LED category and does not affect functional performance in standard indication applications. WP1503ID maintains ROHS3 compliance and MSL 1 rating. Selection is appropriate when Kingbright sourcing is preferred or when Lumex parts are unavailable. No design or circuit modifications are required for substitution.

Compliance Verification: All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity). Selection among these parts does not introduce compliance risk in regulated applications.

Frequently Asked Questions (FAQ)

Q: Can SSL-LX5093LID be used as a direct replacement for SSL-LX509F3ID? A: Yes. SSL-LX5093LID is a parametric equivalent with identical electrical and mechanical specifications. The only difference is packaging configuration. No circuit modifications are required.

Q: What is the wavelength difference between SSL-LX509F3ID and WP1503ID? A: SSL-LX509F3ID has a peak wavelength of 635nm, while WP1503ID has a peak wavelength of 627nm. Both are within the red LED spectrum. For standard indication applications, this difference does not affect functional performance.

Q: Are all three parts ROHS3 compliant? A: Yes. SSL-LX509F3ID, SSL-LX5093LID, and WP1503ID are all ROHS3 compliant and REACH unaffected.

Q: Do the substitute parts have the same physical dimensions? A: Yes. All three parts share identical mechanical specifications: 5mm T-1 3/4 lens size, 8.60mm maximum height, radial package configuration, and through-hole mounting type.

Q: Can WP1503ID be substituted for SSL-LX509F3ID in any application? A: WP1503ID meets all primary electrical and mechanical parameters for standard indication applications. The wavelength difference is minor and does not affect functional performance in typical LED indicator circuits.
