SSL-LX305F4HD Equivalent & Substitute Parts

Part Overview

The SSL-LX305F4HD is a red diffused LED indicator manufactured by Lumex Opto/Components Inc., designed for through-hole mounting applications requiring discrete 2V radial configuration. This component is classified as Active product status and is currently in stock with 915 units available. The SSL-LX305F4HD serves as a standard red LED indication element in electronic assemblies where visual feedback is required.

Substitute parts become necessary when the primary component reaches end-of-life status, experiences supply constraints, or when design revisions require alternative packaging or mechanical configurations while maintaining functional equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSL-LX305F4HD is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Non-Negotiable):

• Forward Voltage (Vf): 2V
• Test Current: 20mA
• Millicandela Rating: 6mcd
• Wavelength - Peak: 700nm
• Viewing Angle: 60°

Optical Parameters (Non-Negotiable):

• Color: Red
• Lens Transparency: Diffused
• Lens Size: 3mm, T-1

Mechanical Parameters (Non-Negotiable):

• Mounting Type: Through Hole
• Package / Case: Radial
• Supplier Device Package: T-1

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected
• Moisture Sensitivity Level: 1 (Unlimited)

The SSL-LX3044HD qualifies as a parametric equivalent based on complete alignment with all electrical, optical, and mechanical parameters listed above. Variations in packaging format (Bulk vs. standard), inventory levels, and product status (Obsolete vs. Active) do not affect functional substitution capability when all core parameters match.

Parameter Comparison

Engineering Selection Recommendations

SSL-LX3044HD Substitution Criteria:

The SSL-LX3044HD is functionally equivalent to the SSL-LX305F4HD across all critical electrical, optical, and mechanical parameters. Both components meet ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment in applications requiring environmental and hazardous substance restrictions.

Key Consideration - Product Status:

The SSL-LX3044HD carries Obsolete product status, indicating discontinued manufacturing. Selection of this substitute should be limited to applications where:

1. Existing inventory of SSL-LX3044HD is available and verified
2. Long-term supply chain continuity is not a design requirement
3. The lower maximum height (4.60mm vs. 5.00mm) is mechanically compatible with the PCB layout and enclosure constraints

Preferred Selection Logic:

For new designs or applications requiring long-term component availability, the SSL-LX305F4HD (Active status) is the primary selection. The SSL-LX3044HD serves as a direct functional substitute only when the Active component is unavailable and the Obsolete component inventory is confirmed accessible.

Compliance Verification:

Both components satisfy ROHS3 Compliant and REACH Unaffected requirements. No additional compliance testing is required when substituting between these two parts in regulated applications.

Frequently Asked Questions (FAQ)

Q1: Can SSL-LX3044HD be used as a direct replacement for SSL-LX305F4HD in existing designs?

A: Yes. The SSL-LX3044HD is a parametric equivalent with identical electrical characteristics (2V forward voltage, 20mA test current, 6mcd brightness, 700nm peak wavelength, 60° viewing angle) and optical properties (red diffused lens, 3mm T-1 package). Both components use radial through-hole mounting. The mechanical difference is a 0.40mm reduction in maximum height (4.60mm vs. 5.00mm), which is compatible with standard PCB layouts unless space constraints are critical.

Q2: What is the primary reason to consider SSL-LX3044HD as a substitute?

A: The SSL-LX3044HD should be considered only when SSL-LX305F4HD (Active status) experiences supply unavailability. The substitute carries Obsolete product status, meaning it is no longer manufactured. Use this part only if existing inventory is confirmed and accessible through authorized distributors.

Q3: Are there compliance differences between these two parts?

A: No. Both SSL-LX305F4HD and SSL-LX3044HD are ROHS3 Compliant and REACH Unaffected. Regulatory requirements are identical, and no additional compliance documentation is required when substituting between these components.

Q4: Does the height difference (5.00mm vs. 4.60mm) affect circuit performance?

A: No. The height difference does not affect electrical performance, brightness output, or viewing angle. The lower profile of SSL-LX3044HD may provide a mechanical advantage in space-constrained applications but requires verification that the reduced height does not conflict with enclosure or lens design requirements.

Q5: What packaging formats are available for these parts?

A: SSL-LX305F4HD is supplied in standard packaging format. SSL-LX3044HD is supplied in Bulk packaging. Both use identical T-1 radial through-hole configuration. Packaging format does not affect component functionality or substitution eligibility.

Q6: Can SSL-LX305F4HD and SSL-LX3044HD be mixed in the same production batch?

A: Yes, provided that the mechanical height difference (0.40mm) does not create visual or functional inconsistencies in the final assembly. If uniform LED height is a design requirement, parts should not be mixed. Verify with manufacturing and quality assurance before implementing mixed-part strategies.
