LED Circuit Board Indicator 5323F7 Equivalent & Substitute Parts

Part Overview

The 5323F7 is a yellow LED circuit board indicator manufactured by Visual Communications Company (VCC) in the T-1 form factor with right-angle through-hole mounting. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. The 5323F7 features a diffused, tinted lens with a domed top, rated for 30mA operation at 2.1V, and delivers 6.3 millicandela output at a peak wavelength of 583nm. ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1) support deployment in standard industrial and commercial applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 5323F7 is based on the following critical parameters that must align between the original and substitute component:

Primary Substitution Criteria:

• Color and Wavelength: Yellow indicator function requires 583nm peak wavelength
• Configuration: Single LED element
• Mounting Type: Through-hole, right-angle orientation for PCB integration
• Lens Characteristics: Diffused lens with domed top for standard indicator visibility
• Electrical Compatibility: Forward voltage and current ratings must support existing circuit designs
• Compliance: ROHS3 compliance required for regulatory alignment
• Form Factor: T-1 or 3mm lens size acceptable within standard indicator envelope constraints

The HLMP1401101F from Dialight meets these substitution criteria as an active, currently manufactured alternative with compatible electrical and mechanical specifications.

Engineering Selection Recommendations

Primary Substitute: HLMP1401101F (Dialight)

The HLMP1401101F is the qualified substitute for the obsolete 5323F7. Selection is based on the following engineering factors:

Compliance and Status: The HLMP1401101F is an active product with current manufacturing support, eliminating obsolescence risk. Both components maintain ROHS3 compliance and unlimited MSL rating, ensuring regulatory and environmental compatibility with existing supply chain requirements.

Electrical Parameters: The substitute operates at 2V forward voltage (0.1V lower than the original 2.1V) and 20mA rated current (10mA lower than the original 30mA specification). These differences are within acceptable tolerance for standard indicator circuit designs that employ current-limiting resistors. Circuit designers must verify that existing current-limiting resistor values accommodate the 20mA maximum rating of the substitute.

Optical Performance: The HLMP1401101F delivers 7 millicandela output compared to the original 6.3mcd, providing equivalent or superior brightness for indicator applications. Both components share identical 583nm peak wavelength, ensuring color consistency in visual indication systems.

Mechanical Compatibility: Both components feature T-1 form factor with right-angle through-hole mounting, round domed-top lens, and diffused optics. Physical envelope and PCB footprint compatibility is maintained, allowing direct substitution without circuit board redesign.

Procurement Advantage: The HLMP1401101F is available in active inventory (1044 pieces) with ongoing manufacturing support, providing long-term supply security compared to the obsolete 5323F7.

Frequently Asked Questions (FAQ)

Q: Can the HLMP1401101F directly replace the 5323F7 without circuit modification?

A: Direct mechanical and optical replacement is possible. However, circuit verification is required because the substitute is rated for 20mA maximum current versus the original 30mA. If the original circuit supplies 30mA to the 5323F7, the current-limiting resistor must be adjusted to limit current to 20mA for the HLMP1401101F. The forward voltage difference (2V vs. 2.1V) is negligible for standard indicator circuits.

Q: Are there differences in lens appearance between the two parts?

A: Both components feature diffused, round domed-top lenses in T-1 form factor. The 5323F7 specifies "diffused, tinted" while the HLMP1401101F specifies "diffused" without tint notation. Visual appearance may differ slightly; if lens tint is critical to the application, physical samples should be evaluated.

Q: What is the significance of the 3mm designation on the HLMP1401101F?

A: The HLMP1401101F is listed as "3mm, T-1" lens size. This indicates the physical diameter of the lens element. T-1 is a standard form factor designation. Both designations are compatible and refer to the same standard indicator package size used in through-hole PCB applications.

Q: Is the HLMP1401101F suitable for high-brightness applications?

A: The HLMP1401101F delivers 7 millicandela, which is slightly higher than the original 5323F7 at 6.3 millicandela. For standard circuit board indicator applications, this brightness level is appropriate. If higher brightness is required, alternative LED indicators with higher millicandela ratings should be evaluated separately.

Q: Are both components RoHS compliant?

A: Yes. Both the 5323F7 and HLMP1401101F are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the viewing angle specification for the HLMP1401101F?

A: The HLMP1401101F specifies a 60-degree viewing angle. This is typical for diffused indicator LEDs and provides adequate visibility across standard viewing positions for circuit board indicator applications. The original 5323F7 does not specify a viewing angle parameter.
