SSF-LXH303USBD LED Circuit Board Indicator Equivalent & Substitute Parts

Part Overview

The SSF-LXH303USBD is an active LED circuit board indicator manufactured by Lumex Opto/Components Inc. This component is a single blue diffused LED with a 3mm T-1 form factor, designed for through-hole right-angle PCB mounting applications. The device operates at 3.5V with a 20mA forward current and delivers 80 millicandela luminous intensity at a 60-degree viewing angle.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and compliance certifications are maintained across alternative part numbers within the same manufacturer's product line. This reference enables procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSF-LXH303USBD is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Forward voltage rating: 3.5V
• Forward current: 20mA
• Peak wavelength: 470nm (blue spectrum)
• Luminous intensity: 80mcd
• Viewing angle: 60°

Mechanical Equivalence Requirements:

• Lens size: 3mm, T-1 form factor
• Lens style: Round with domed top
• Mounting type: Through hole, right angle PCB orientation
• Configuration: Single LED

Compliance Requirements:

• RoHS3 compliance
• REACH unaffected status
• Active product status

The SSF-LXH103USBD meets all electrical and mechanical equivalence criteria. The primary distinction is the lens material specification (diffused tinted versus diffused blue), which does not affect electrical performance or mechanical compatibility in through-hole right-angle applications.

Parameter Comparison

Engineering Selection Recommendations

Both SSF-LXH303USBD and SSF-LXH103USBD are active products with identical electrical specifications and mechanical form factors. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications.

Selection between these parts is based on packaging availability and inventory status. The SSF-LXH303USBD is available in standard packaging with 714 units in stock. The SSF-LXH103USBD is supplied in bulk packaging with 1512 units in stock and includes a defined Moisture Sensitivity Level (MSL) rating of 1 (unlimited).

For applications requiring high-volume procurement or extended supply chain assurance, the SSF-LXH103USBD offers greater inventory availability. Both parts deliver equivalent electrical performance and mechanical compatibility in through-hole right-angle PCB mounting configurations.

Frequently Asked Questions (FAQ)

Q: Are SSF-LXH303USBD and SSF-LXH103USBD electrically interchangeable?

A: Yes. Both parts operate at 3.5V forward voltage, 20mA forward current, and deliver 80mcd luminous intensity at 470nm peak wavelength with a 60-degree viewing angle. Electrical performance is identical.

Q: What is the difference between diffused blue and diffused tinted lens materials?

A: Both lens types are diffused finishes that scatter light. The diffused blue lens (SSF-LXH303USBD) and diffused tinted lens (SSF-LXH103USBD) produce equivalent optical output in terms of luminous intensity and viewing angle. The material distinction does not affect electrical performance or mechanical compatibility.

Q: Can these parts be used interchangeably in right-angle through-hole applications?

A: Yes. Both parts feature identical 3mm T-1 form factors with round domed tops and right-angle through-hole mounting. Mechanical compatibility is complete.

Q: What is the Moisture Sensitivity Level (MSL) for the SSF-LXH303USBD?

A: The MSL specification is not provided for the SSF-LXH303USBD. The SSF-LXH103USBD carries an MSL rating of 1 (unlimited), indicating no moisture sensitivity restrictions.

Q: Are both parts RoHS3 compliant?

A: Yes. Both SSF-LXH303USBD and SSF-LXH103USBD are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for restricted substance use.

Q: Which part should be selected for new designs?

A: Both parts are active products suitable for new designs. Selection depends on packaging requirements and inventory availability. The SSF-LXH103USBD offers higher stock levels in bulk packaging.
