LED Circuit Board Indicator 5370T5 Equivalent & Substitute Parts

Part Overview

The VCC 5370T5 is a 2.00mm diameter through-hole LED circuit board indicator featuring a single green diffused, tinted lens with domed top. Designed for 2.3V operation at 10mA with a peak wavelength of 565nm and 4 millicandela rating, this component is classified as obsolete. Due to its discontinued status, identifying functionally compatible substitute components is necessary for ongoing design support, maintenance applications, and production continuity where original inventory is depleted.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the 5370T5 are identified based on the following critical parameters:

Primary Matching Criteria:

• Color: Green (565nm wavelength range)
• Configuration: Single LED
• Mounting Type: Through Hole
• Lens Type: Diffused, Tinted
• Compliance: ROHS3 Compliant, REACH Unaffected

Acceptable Variation Parameters:

• Voltage Rating: 2.2V to 2.4V range (±0.1V tolerance)
• Current: 10mA to 20mA (circuit design dependent)
• Lens Size: Physical dimensions may vary (2.00mm to 5mm) based on PCB layout accommodation
• Millicandela Rating: Higher brightness acceptable for same application

The Dialight 5505204F qualifies as a substitute based on matching color, configuration, mounting type, lens characteristics, and compliance certifications. Variations in lens size (5mm vs 2mm), current rating (20mA vs 10mA), and brightness (34mcd vs 4mcd) represent acceptable engineering trade-offs for obsolete component replacement.

Parameter Comparison

Engineering Selection Recommendations

Compliance and Regulatory Basis:

Both the VCC 5370T5 and Dialight 5505204F maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements for electronic component use in regulated markets.

Product Status Consideration:

The 5370T5 is classified as obsolete, indicating discontinued manufacturing and limited inventory availability. The Dialight 5505204F maintains active product status with confirmed inventory of 1408 pieces, ensuring supply chain continuity and long-term availability for production and maintenance applications.

Substitution Validity:

The 5505204F qualifies as an engineering substitute based on:

• Identical color and wavelength specification within acceptable green spectrum range
• Matching single-LED configuration and through-hole mounting type
• Equivalent lens characteristics (diffused, tinted, domed top)
• Equivalent compliance certifications
• Higher brightness rating (34mcd vs 4mcd) acceptable for indicator applications
• Active manufacturing status supporting ongoing component sourcing

Circuit Integration Considerations:

The 20mA current rating of the substitute versus the 10mA rating of the original part requires verification of series resistor values in the circuit design. The 0.1V voltage difference (2.2V vs 2.3V) falls within standard circuit tolerance margins and does not require design modification.

Physical Integration Consideration:

The 5mm lens diameter of the substitute versus the 2mm diameter of the original part requires confirmation that PCB hole spacing and mechanical mounting accommodate the larger component footprint.

Frequently Asked Questions (FAQ)

Q: Can the Dialight 5505204F directly replace the VCC 5370T5 without circuit modification?

A: The substitute is electrically compatible with minor considerations. The 0.1V voltage difference is within standard tolerance. However, the 20mA current rating versus 10mA requires verification that the series resistor in the circuit is appropriately sized for the substitute component. Physical verification that the 5mm lens diameter fits the PCB mounting holes is also required.

Q: What is the significance of the wavelength difference between 565nm and 563nm?

A: Both wavelengths fall within the green spectrum range for LED indicators. The 2nm difference is imperceptible to human vision and does not affect the functional indication capability of the component.

Q: Why is the substitute component rated at 20mA instead of 10mA?

A: The 20mA rating reflects the Dialight component's design specifications. In circuit applications, the actual current drawn is determined by the series resistor value. Existing circuit designs using 10mA can accommodate the substitute by maintaining the same resistor value, though the substitute will operate at its rated 20mA capability if the circuit design permits.

Q: Does the larger 5mm lens size affect the indicator function?

A: The larger lens size does not affect the indicator function but requires physical verification that the PCB mounting holes and component spacing accommodate the 5mm diameter. The domed top lens style remains consistent between both components.

Q: Are both components suitable for new production designs?

A: The VCC 5370T5 is obsolete and unsuitable for new production. The Dialight 5505204F, with active product status and confirmed inventory, is appropriate for new production designs requiring green through-hole LED indicators with the specified electrical and optical characteristics.

Q: What compliance certifications apply to the substitute component?

A: The Dialight 5505204F maintains ROHS3 compliance and REACH unaffected status, matching the regulatory certifications of the original component. Both components carry EAR99 ECCN classification and 8541.41.0000 HTSUS code.
