LED Circuit Board Indicator 5325F3 Equivalent & Substitute Parts

Part Overview

The VCC 5325F3 is a 3mm through-hole right-angle LED circuit board indicator featuring amber light output at 603nm peak wavelength. This component is designed for applications requiring a compact, domed-top indicator lens with 2.2V forward voltage and 30mA operating current. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5325F3 is determined by the following critical parameters that must align with the original component specifications:

Mechanical Compatibility: Lens size (3mm, T-1), lens style (round with domed top), and mounting type (through-hole, right-angle) establish physical interchangeability within circuit board layouts.

Optical Compatibility: Color (amber) and wavelength range (603nm ±10nm acceptable) ensure visual consistency and circuit function recognition.

Electrical Compatibility: Forward voltage (2.2V ±0.3V) and current rating (30mA ±10mA) determine circuit integration without requiring redesign of current-limiting resistor networks.

Regulatory Compliance: RoHS3 compliance and MSL rating (1 - Unlimited) confirm environmental and manufacturing process compatibility.

The Lumex Opto/Components Inc. SSF-LXH303AD meets the primary mechanical and optical criteria but exhibits variations in electrical parameters that require engineering evaluation.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: The Lumex SSF-LXH303AD is an active product with confirmed availability, addressing the obsolescence status of the VCC 5325F3.

Electrical Parameter Variations: The substitute operates at 2V forward voltage (versus 2.2V) and 20mA current (versus 30mA). These reductions require circuit verification to confirm compatibility with existing current-limiting resistor values and power supply specifications.

Optical Characteristics: The diffused lens type on the SSF-LXH303AD differs from the clear, tinted lens of the 5325F3. The higher millicandela rating (30mcd versus 4mcd) indicates increased brightness output. Visual appearance and perceived intensity in the application environment may differ.

Compliance Status: Both components maintain ROHS3 compliance and unlimited moisture sensitivity ratings, confirming environmental and manufacturing process compatibility.

Recommendation Basis: Selection of the SSF-LXH303AD as a substitute is supported by mechanical interchangeability, active product status, and regulatory compliance. Electrical parameter variations and lens type differences must be validated against specific circuit requirements and visual performance expectations.

Frequently Asked Questions (FAQ)

Q: Can the Lumex SSF-LXH303AD be directly substituted for the VCC 5325F3 without circuit modification?

A: Physical installation is compatible due to matching 3mm T-1 through-hole right-angle packaging. However, the reduced forward voltage (2V versus 2.2V) and current rating (20mA versus 30mA) require verification of existing current-limiting resistor calculations. Circuit redesign may be necessary depending on power supply voltage and resistor tolerance specifications.

Q: What is the impact of the diffused lens on visual performance?

A: The SSF-LXH303AD features a diffused lens compared to the clear, tinted lens of the 5325F3. Diffused lenses scatter light over a wider viewing angle, reducing peak brightness intensity at the lens center but improving visibility across a broader angular range. The higher millicandela rating (30mcd) partially compensates for this optical characteristic.

Q: Are both components RoHS compliant?

A: Yes. Both the VCC 5325F3 and Lumex SSF-LXH303AD are ROHS3 compliant and carry MSL rating 1 (unlimited moisture sensitivity), confirming compatibility with modern manufacturing and environmental standards.

Q: Why is the VCC 5325F3 classified as obsolete?

A: Obsolescence status indicates the manufacturer has discontinued production. The Lumex SSF-LXH303AD represents an active alternative for ongoing procurement and design support.

Q: What parameters must match for successful substitution?

A: Mechanical compatibility requires matching lens size (3mm, T-1), mounting type (through-hole, right-angle), and lens style (round with domed top). Optical compatibility requires amber color and wavelength within ±10nm of 603nm. Electrical compatibility requires forward voltage within ±0.3V and current rating within ±10mA of the original specification.
