LED Circuit Board Indicator 5372T3-5VLC Equivalent & Substitute Parts

Part Overview

The 5372T3-5VLC is a 2mm amber LED circuit board indicator manufactured by Visual Communications Company (VCC), designed for through-hole mounting applications requiring a 5V, 3.5mA single amber diffused indicator with a domed lens. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement continuity. The part maintains ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), making it suitable for standard industrial and commercial applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute identification for the 5372T3-5VLC is based on the following critical parameters that define functional equivalence:

Primary Matching Criteria:

• Color: Amber (wavelength region 565nm)
• Configuration: Single LED element
• Mounting Type: Through Hole
• Lens Style: Round with Domed Top
• Lens Type: Diffused
• RoHS3 Compliance
• MSL 1 Rating

Secondary Considerations:

• Voltage Rating: 5V operation
• Current Rating: 3.5mA nominal
• Lens Size: 2.00mm diameter (mechanical fit constraint)

The substitute part 5615401060F from Dialight shares the core functional characteristics (amber color, single configuration, through-hole mounting, diffused domed lens, RoHS3 compliance, MSL 1 rating) but differs in lens size (5.00mm vs 2.00mm), current rating (20mA vs 3.5mA), and brightness (34mcd vs 4mcd). These differences indicate a larger form factor with higher power consumption and brightness output.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility Assessment:

The 5615401060F presents a viable alternative for applications where the 5372T3-5VLC is no longer available, provided the following conditions are met:

1. Mechanical Compatibility: The 5.00mm lens diameter of the 5615401060F is significantly larger than the 2.00mm diameter of the original part. PCB layout modifications and mechanical clearance verification are required. Direct drop-in replacement is not possible without design changes.

2. Electrical Compatibility: The substitute operates at 20mA versus the original 3.5mA. Circuit redesign or current-limiting resistor adjustment is necessary. The original 5V voltage rating is not specified for the substitute; circuit validation is required.

3. Optical Performance: The 5615401060F provides 34mcd brightness compared to 4mcd for the original. This 8.5x increase in brightness may affect visual perception and circuit design intent. Application-specific evaluation is necessary.

4. Regulatory Compliance: Both parts maintain ROHS3 compliance and MSL 1 rating, satisfying environmental and moisture sensitivity requirements.

5. Availability: The 5615401060F is listed as active product status with 1068 units in stock, ensuring procurement continuity compared to the obsolete 5372T3-5VLC.

Recommendation: The 5615401060F is electrically and optically compatible in function but requires mechanical and electrical circuit modifications. Use only when design constraints permit larger form factor and higher current consumption.

Frequently Asked Questions (FAQ)

Q1: Can the 5615401060F be used as a direct drop-in replacement for the 5372T3-5VLC?

A: No. The 5615401060F has a 5.00mm lens diameter compared to the 2.00mm diameter of the original part. This size difference requires PCB layout modifications and mechanical clearance verification. Direct substitution without design changes is not possible.

Q2: What are the key electrical differences between these parts?

A: The 5372T3-5VLC operates at 3.5mA, while the 5615401060F operates at 20mA. This 5.7x increase in current consumption requires circuit evaluation and potential resistor adjustments. The original part specifies 5V operation; the substitute voltage rating is not provided in available data.

Q3: Will the brightness difference affect my application?

A: The 5615401060F produces 34mcd compared to 4mcd for the original part, representing an 8.5x increase in brightness. Applications requiring specific brightness levels for visual indication or human factors compliance must evaluate this difference. Excessive brightness may cause glare or unintended visual effects.

Q4: Are both parts compliant with environmental regulations?

A: Yes. Both the 5372T3-5VLC and 5615401060F are ROHS3 compliant and carry MSL 1 (unlimited moisture sensitivity) ratings, meeting standard environmental and storage requirements for industrial applications.

Q5: What is the primary reason for seeking a substitute?

A: The 5372T3-5VLC is classified as obsolete, meaning the manufacturer has discontinued production. The 5615401060F is an active product with confirmed inventory availability, ensuring long-term procurement continuity.

Q6: Are there any other amber LED indicators available as alternatives?

A: The provided data includes only the 5615401060F as a documented substitute. Additional alternatives may exist from other manufacturers; however, only parts explicitly provided in this reference should be considered for engineering selection.

Q7: What testing or validation is required before implementing the 5615401060F?

A: Circuit simulation and prototype testing are necessary to validate electrical performance at 20mA current draw, verify brightness acceptability for the application, and confirm mechanical fit within PCB constraints. Voltage rating confirmation for the substitute is also required.
