Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5340H5-5V is determined by the following critical parameters that must remain constant or compatible:

Mandatory Matching Parameters:

• Voltage Rating: 5V
• Lens Size: 5mm, T-1 3/4
• Mounting Type: Through Hole
• Color: Green
• Wavelength - Peak: 565nm
• Configuration: Single
• Millicandela Rating: 8mcd

Allowable Variation Parameters:

• Current Rating: The substitute may operate at a higher current rating (12mA vs. 10mA) provided the circuit design accommodates the increased current draw
• Lens Type: Diffused (without tinting) is acceptable as a substitute for Diffused, Tinted
• Viewing Angle: Addition of specified viewing angle (60°) does not affect substitution compatibility

The 5500704F from Dialight meets all mandatory matching criteria and represents an active product with equivalent electrical and mechanical characteristics suitable for direct substitution in applications previously designed for the 5340H5-5V.

Parameter Comparison

Engineering Selection Recommendations

The 5500704F from Dialight is the qualified substitute for the obsolete 5340H5-5V. Selection of this substitute is based on the following engineering criteria:

Compliance and Regulatory Alignment: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications subject to environmental and hazardous substance restrictions.

Electrical Compatibility: The 5V voltage rating and 8mcd brightness specification are identical between the main part and substitute. The substitute operates at 12mA compared to the original 10mA specification. Circuit designs must accommodate this 2mA increase in current draw. For applications with current-limiting resistors, recalculation of resistor values may be necessary to maintain proper LED operation within the substitute's rated parameters.

Mechanical and Optical Compatibility: Both components feature identical 5mm T-1 3/4 through-hole form factors with round domed top lenses. The substitute's diffused lens (without tinting) provides equivalent optical diffusion characteristics for circuit board indicator applications. The addition of a 60° viewing angle specification on the substitute does not restrict compatibility.

Product Status Advantage: The 5500704F is an active product with confirmed inventory availability (2068 pcs), ensuring long-term supply chain reliability for new production and design revisions.

Frequently Asked Questions (FAQ)

Q: Can the 5500704F directly replace the 5340H5-5V without circuit modifications?

A: The 5500704F is mechanically and electrically compatible for direct substitution in through-hole PCB applications. However, the increased current rating (12mA vs. 10mA) requires verification that existing current-limiting circuits can accommodate the 2mA increase. If the circuit uses a fixed resistor for current limiting, resistor value adjustment may be necessary to maintain proper LED operation.

Q: What is the significance of the lens type difference (Diffused, Tinted vs. Diffused)?

A: Both lens types provide diffusion for circuit board indicator applications. The removal of tinting in the substitute does not affect functional compatibility. Visual appearance may differ slightly due to the absence of tinting, but optical performance for indicator purposes remains equivalent.

Q: Are there any compliance or certification concerns with substitution?

A: Both components maintain identical RoHS3 compliance and REACH unaffected status. No compliance barriers exist for substitution in regulated applications.

Q: What is the viewing angle specification on the substitute, and does it affect compatibility?

A: The 5500704F specifies a 60° viewing angle, whereas the original part does not provide this specification. A defined viewing angle indicates the angular range over which the LED maintains specified brightness. This addition does not restrict compatibility; it provides additional technical documentation for the substitute component.

Q: Is the 5500704F available in the same packaging as the 5340H5-5V?

A: The 5500704F is supplied in bulk packaging. Both components are through-hole mounted with identical 5mm T-1 3/4 form factors, ensuring compatibility with existing PCB designs and assembly processes.

Q: What inventory considerations should be evaluated for this substitution?

A: The 5340H5-5V is obsolete with 778 pcs in stock. The 5500704F is an active product with 2068 pcs available, providing superior long-term supply chain security for ongoing production requirements.
