SSF-LXH475LIIIXD Equivalent & Substitute Parts

Part Overview

The SSF-LXH475LIIIXD is a LED Circuit Board Indicator manufactured by Lumex Opto/Components Inc. This component features a 4-high configuration with three red LEDs and one blank position, designed for through-hole right-angle mounting on circuit boards. The part operates at 2.0V with a 30mA current rating and delivers 40mcd brightness with a 60° viewing angle. The product is currently classified as obsolete, necessitating identification of equivalent substitute components that maintain functional and mechanical compatibility for ongoing applications and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSF-LXH475LIIIXD is determined by strict alignment of the following critical parameters:

Electrical Parameters:

• Voltage Rating: 2.0V
• Current: 30mA
• Wavelength - Peak: 635nm
• Configuration: 4 High
• Color: Red (x 3), Blank (x 1)

Mechanical Parameters:

• Lens Size: 3mm, T-1
• Lens Style: Round with Domed Top
• Mounting Type: Through Hole, Right Angle

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• MSL: 1 (Unlimited)

The substitute part 5680101110F manufactured by Dialight meets all critical electrical and mechanical parameters. Variations in millicandela rating (40mcd vs. 10mcd) and lens type specification do not disqualify substitution when the primary functional requirements and physical form factors align.

Parameter Comparison

Engineering Selection Recommendations

The 5680101110F from Dialight serves as a direct functional substitute for the obsolete SSF-LXH475LIIIXD. Both components share identical electrical specifications (2V/30mA operation, 635nm wavelength, 4-high configuration with red/blank color pattern) and mechanical form factors (3mm through-hole right-angle mounting with domed lens style). Both components maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), ensuring regulatory and environmental compatibility.

The primary distinction is product status: the Dialight part is currently active in production with confirmed inventory availability (903 pcs), whereas the Lumex component is obsolete. The Dialight substitute is suitable for direct replacement in existing designs and for new applications requiring this LED indicator configuration.

Frequently Asked Questions (FAQ)

Q: Can the 5680101110F directly replace the SSF-LXH475LIIIXD in existing circuit board designs?

A: Yes. Both components share identical voltage (2V), current (30mA), wavelength (635nm), configuration (4-high), color pattern (red x3, blank x1), lens size (3mm), lens style (domed), and mounting type (through-hole right-angle). Physical and electrical compatibility is confirmed.

Q: What is the significance of the millicandela rating difference (40mcd vs. 10mcd)?

A: The Lumex part delivers 40mcd brightness while the Dialight substitute delivers 10mcd. This represents a reduction in luminous intensity. Applications requiring the original 40mcd brightness specification should evaluate whether the 10mcd output meets functional requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the SSF-LXH475LIIIXD and 5680101110F are ROHS3 compliant and carry unlimited moisture sensitivity level (MSL 1), meeting current regulatory requirements.

Q: What packaging is available for the substitute part?

A: The 5680101110F is supplied in bulk packaging with 903 pcs currently in stock.

Q: Why is the original Lumex part listed as obsolete?

A: Product obsolescence indicates the manufacturer has discontinued production. The Dialight 5680101110F remains in active production status, making it the recommended source for ongoing component procurement.
