Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLH-56VR3F is determined by the following critical parameters:

• Lens Size and Form Factor: 5mm T-1 3/4 through-hole radial package
• Color and Wavelength Range: Red spectrum (650nm peak wavelength for SLH-56VR3F)
• Mounting Type: Through-hole radial configuration
• Forward Voltage Range: Nominal 2.0V to 2.1V
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The SLR-56VR3F qualifies as a substitute based on matching lens size, radial through-hole mounting, red color specification, and regulatory compliance. Variations in millicandela rating, test current, and exact wavelength represent acceptable parameter tolerances within the red LED indicator category.

Parameter Comparison

Engineering Selection Recommendations

The SLR-56VR3F serves as an active substitute for the obsolete SLH-56VR3F. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and production continuity.

The SLR-56VR3F is currently in active production with substantial inventory availability (100,100 pieces), providing supply chain stability compared to the obsolete SLH-56VR3F status. The substitute maintains identical mechanical form factor (5mm T-1 3/4 radial through-hole) and optical properties (red diffused lens).

Parameter differences include forward voltage (2.0V versus 2.1V) and test current (10mA versus 20mA), representing acceptable operational variations within red LED indicator specifications. The SLR-56VR3F achieves a lower millicandela rating (10mcd versus 47mcd), which may require circuit design evaluation if brightness-dependent functionality is specified.

Frequently Asked Questions (FAQ)

Q: Can the SLR-56VR3F directly replace the SLH-56VR3F in existing designs?

A: The SLR-56VR3F is mechanically and electrically compatible for through-hole mounting applications. The identical 5mm T-1 3/4 form factor and radial package ensure PCB footprint compatibility. Forward voltage difference (2.0V versus 2.1V) is within typical LED tolerance ranges and requires only minor circuit adjustment if current-limiting resistor values were precisely calculated for the original part.

Q: What are the key differences between these two parts?

A: Primary differences include product status (active versus obsolete), millicandela rating (10mcd versus 47mcd), test current specification (10mA versus 20mA), and dominant wavelength documentation (630nm versus 650nm peak). Both maintain identical lens size, color, transparency, mounting type, and regulatory compliance.

Q: Are there packaging differences between SLH-56VR3F and SLR-56VR3F?

A: The SLH-56VR3F is supplied in Tape & Reel (TR) packaging, while the SLR-56VR3F is supplied in Bulk packaging. Both use identical radial through-hole component form factors suitable for standard PCB assembly processes.

Q: Does the lower millicandela rating of the SLR-56VR3F affect circuit design?

A: The SLR-56VR3F produces lower light output (10mcd versus 47mcd). Applications requiring specific brightness levels must evaluate whether this reduction impacts visual indication requirements. Circuit design modifications are not required for basic electrical compatibility.

Q: Are both parts compliant with current regulatory standards?

A: Both the SLH-56VR3F and SLR-56VR3F maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and use.
