LED Circuit Board Indicator 5323F1 Equivalent & Substitute Parts

Part Overview

The 5323F1 is a red LED circuit board indicator manufactured by Visual Communications Company (VCC), designed for through-hole, right-angle mounting applications. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing production support, maintenance, and design continuity. The 5323F1 operates at 2V with a 30mA current rating and delivers 10mcd luminous intensity in a T-1 form factor with diffused, tinted lens.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5323F1 must satisfy the following mandatory criteria:

Critical Parameters (Must Match or Be Compatible):

• Color: Red
• Configuration: Single LED element
• Current Rating: 30mA
• Mounting Type: Through Hole, Right Angle
• Wavelength Range: Red spectrum (645nm–650nm acceptable)

Important Parameters (Should Match):

• Voltage Rating: 2V nominal (1.6V–2V range acceptable for circuit compatibility)
• Lens Style: Round with Domed Top
• RoHS Compliance: ROHS3 Compliant

Flexible Parameters (May Vary):

• Lens Size: T-1 or 3.00mm diameter (both are standard through-hole form factors)
• Millicandela Rating: Brightness may vary within application tolerance
• Viewing Angle: May differ based on lens design

The HLMPK101101F from Dialight meets these substitution criteria as an active product with compatible electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The HLMPK101101F is a direct functional substitute for the obsolete 5323F1 based on the following engineering criteria:

1. Electrical Compatibility: Both components operate at 30mA current rating. The voltage difference (2V vs. 1.6V) is within acceptable tolerance for most circuit designs using current-limiting resistors. Circuit verification is required if voltage-sensitive applications are present.

2. Mechanical Compatibility: Both components feature through-hole, right-angle mounting with round domed-top lens styles. Physical PCB layout compatibility is confirmed.

3. Optical Compatibility: Both emit red light within the 645nm–650nm wavelength range. The brightness difference (10mcd vs. 2mcd) must be evaluated against application requirements; the HLMPK101101F is dimmer and may require circuit adjustment if brightness is critical.

4. Regulatory Compliance: Both components are ROHS3 compliant with identical export classifications (EAR99) and tariff codes (8541.41.0000), ensuring regulatory continuity.

5. Product Status: The HLMPK101101F is an active product with confirmed inventory availability (1184 pcs), providing supply chain continuity for the obsolete 5323F1.

Selection Criteria:

• Use HLMPK101101F as primary substitute for new designs and production support
• Verify circuit tolerance for 0.4V voltage difference in existing designs
• Confirm brightness requirement compatibility; if 10mcd is mandatory, alternative sources must be evaluated
• Validate PCB layout fit for 3.00mm diameter lens versus T-1 form factor

Frequently Asked Questions (FAQ)

Q: Can the HLMPK101101F directly replace the 5323F1 without circuit modification?

A: Electrical substitution is feasible in most applications. The 30mA current rating and through-hole right-angle mounting are identical. However, the voltage rating difference (2V vs. 1.6V) and brightness reduction (10mcd vs. 2mcd) require circuit evaluation. If the original design uses a current-limiting resistor, the HLMPK101101F will operate correctly. If brightness is application-critical, circuit adjustment may be necessary.

Q: What is the physical size difference between T-1 and 3.00mm diameter lenses?

A: T-1 and 3.00mm diameter are equivalent standard through-hole LED form factors. Both are compatible with standard PCB mounting holes. Verify mechanical fit in your specific PCB layout.

Q: Are there compliance or regulatory differences between these parts?

A: No. Both components are ROHS3 compliant, carry EAR99 export classification, and share identical HTSUS tariff code 8541.41.0000. Regulatory continuity is maintained.

Q: Why is the HLMPK101101F dimmer (2mcd vs. 10mcd)?

A: Brightness is determined by LED die design and lens optics. The HLMPK101101F uses different optical engineering. If 10mcd brightness is mandatory for your application, alternative sources must be identified. If the application tolerates lower brightness, the HLMPK101101F is suitable.

Q: Is the 645nm wavelength of the HLMPK101101F compatible with the 650nm specification of the 5323F1?

A: Yes. Both wavelengths fall within the red spectrum and are visually indistinguishable to the human eye. The 5nm difference is within acceptable tolerance for red LED indicators.

Q: What is the viewing angle difference, and does it matter?

A: The 5323F1 does not specify a viewing angle. The HLMPK101101F specifies 60° viewing angle, which is standard for diffused red LEDs. This provides defined optical performance and is suitable for general circuit board indicator applications.

Q: Is the HLMPK101101F available in the same packaging as the 5323F1?

A: The 5323F1 packaging is listed as "-" (not specified). The HLMPK101101F is supplied in Bulk packaging. Confirm packaging requirements for your procurement and assembly processes.
