LED Circuit Board Indicator SSF-LXH475IIIXD Equivalent & Substitute Parts

Part Overview

The SSF-LXH475IIIXD is a quad LED circuit board indicator manufactured by Lumex Opto/Components Inc., configured with three high-brightness red LEDs and one blank position. This component is designed for through-hole, right-angle mounting applications requiring 2.0V operation at 30mA per LED element. The product is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SSF-LXH475IIIXD is determined by strict alignment of the following critical parameters:

Configuration Match: Both the main part and substitute must maintain a 4-high LED arrangement with three red LEDs and one blank position.

Electrical Specifications: Voltage rating (2.0V nominal), current per LED element (30mA), and wavelength (635nm red spectrum) must be identical or functionally equivalent.

Mounting Architecture: Through-hole, right-angle orientation is mandatory for PCB layout compatibility.

Compliance Requirements: RoHS3 compliance and MSL rating of 1 (unlimited moisture sensitivity) must be maintained.

The substitute part 5680101110F from Dialight meets these criteria while offering active product status and current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5680101110F serves as a functional substitute for the obsolete SSF-LXH475IIIXD based on electrical and mechanical parameter alignment. Both components share identical voltage, current, wavelength, configuration, and mounting specifications, ensuring direct circuit compatibility.

The primary distinction is the millicandela rating differential (40mcd versus 10mcd). Applications requiring the original 40mcd brightness specification should evaluate whether the 10mcd output of the Dialight substitute meets luminous intensity requirements for the intended visual indication function.

The Dialight component offers the advantage of active product status with current manufacturing availability, supporting long-term supply chain continuity. Both parts maintain equivalent compliance certifications (ROHS3, MSL 1) and share identical ECCN and HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can the Dialight 5680101110F directly replace the Lumex SSF-LXH475IIIXD without PCB modification?

A: Yes. Both components feature identical through-hole, right-angle mounting specifications and electrical parameters (2.0V, 30mA, 635nm wavelength). No PCB layout changes are required for mechanical or electrical integration.

Q: What is the significance of the millicandela rating difference between the two parts?

A: The SSF-LXH475IIIXD provides 40mcd brightness per LED element, while the 5680101110F provides 10mcd. This represents a 75% reduction in luminous intensity. Applications dependent on specific brightness thresholds for visual detection or compliance with indicator standards must confirm the lower output is acceptable for the intended function.

Q: Are there differences in optical appearance between these components?

A: Yes. The Lumex part features a diffused red lens, while the Dialight part uses a round lens with domed top. This affects light distribution characteristics and viewing profile. Visual appearance in the assembled product may differ despite identical viewing angle specifications.

Q: Do both parts meet current regulatory requirements?

A: Both components are ROHS3 compliant and REACH unaffected. The Dialight 5680101110F, as an active product, maintains current manufacturing compliance. The Lumex part, being obsolete, may not receive updated certifications for future regulatory changes.

Q: What is the inventory status for these parts?

A: The SSF-LXH475IIIXD has 794 pieces in stock (new original). The Dialight 5680101110F has 903 pieces in stock (new original, bulk packaging). The substitute offers superior long-term availability through active manufacturing status.
