LED Circuit Board Indicator 5655F5 Equivalent & Substitute Parts

Part Overview

The VCC 5655F5 is a 3mm through-hole right-angle LED circuit board indicator featuring a green tinted lens with domed top. This component operates at 2.2V with a 10mA rated current and delivers 16 millicandela luminous intensity at a peak wavelength of 562nm. The part is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility, mechanical form factor, and optical performance within specified tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the VCC 5655F5 is based on strict electrical and mechanical compatibility criteria. The following parameters define acceptable equivalents:

Critical Matching Parameters:

• Lens size: 3mm, T-1 form factor
• Mounting configuration: Through hole, right angle orientation
• Color: Green spectrum output
• Rated current: 10mA nominal operation
• Forward voltage: 2.1V to 2.2V range
• Luminous intensity: 16mcd minimum
• Peak wavelength: 562nm to 563nm range
• Configuration: Single LED element

The Dialight 5510207F meets all critical parameters within specified tolerances. Differences in lens type (diffused vs. tinted) and viewing angle represent acceptable variations that do not compromise functional substitution for circuit board indicator applications.

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5510207F is a direct functional equivalent for the obsolete VCC 5655F5. Selection is supported by the following engineering factors:

Electrical Compatibility: Both components operate at 10mA rated current with forward voltages within 0.1V tolerance (2.2V vs. 2.1V). This voltage differential is within acceptable circuit design margins for standard LED current-limiting resistor calculations.

Optical Performance: Peak wavelength values differ by 1nm (562nm vs. 563nm), which is imperceptible in green spectrum applications and maintains color consistency for circuit board indicator functions.

Mechanical Integration: Identical 3mm T-1 through-hole right-angle form factor ensures direct PCB footprint compatibility without layout modifications.

Product Status and Compliance: The substitute part is active in production, ensuring long-term availability. Both components maintain ROHS3 compliance, MSL-1 rating, and REACH unaffected status, satisfying current regulatory requirements.

Lens Characteristic Variation: The Dialight part features diffused tinting compared to the VCC tinted lens. This variation provides a 45-degree viewing angle specification and maintains equivalent luminous intensity for indicator applications.

Frequently Asked Questions (FAQ)

Q: Can the Dialight 5510207F be used as a direct replacement for the VCC 5655F5 in existing designs?

A: Yes. Both components share identical electrical ratings (10mA, 2.1V to 2.2V forward voltage range), mechanical form factor (3mm T-1 through-hole right angle), and luminous intensity (16mcd). PCB footprints and circuit connections are compatible without modification.

Q: What is the significance of the 0.1V voltage difference between the two parts?

A: The forward voltage difference (2.2V vs. 2.1V) is within standard LED circuit design tolerances. Current-limiting resistor values calculated for the original 2.2V specification will operate the 2.1V substitute within rated parameters. No circuit redesign is required.

Q: How does the lens type difference affect performance?

A: The VCC 5655F5 uses a tinted lens, while the Dialight 5510207F uses a diffused, tinted lens. Both deliver 16mcd luminous intensity. The diffused lens on the substitute provides a specified 45-degree viewing angle, which is advantageous for circuit board indicator applications requiring wider visibility.

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

A: No. Both components are ROHS3 compliant, carry MSL-1 (unlimited moisture sensitivity) ratings, and are REACH unaffected. Regulatory status is identical.

Q: What is the wavelength difference significance?

A: The 1nm peak wavelength difference (562nm vs. 563nm) is within the green spectrum range and produces no perceptible color difference in circuit board indicator applications. Both parts deliver equivalent green optical output.

Q: Is the Dialight 5510207F available in the same packaging as the VCC 5655F5?

A: The substitute is supplied in bulk packaging. The original VCC part packaging specification was not provided in the reference data. Confirm packaging requirements with procurement specifications for your application.

Q: Can circuit board designs be updated to use the Dialight part without electrical recalculation?

A: Yes. The 10mA current rating and 2.1V to 2.2V forward voltage range are compatible with existing current-limiting resistor designs. No electrical recalculation is necessary for standard circuit board indicator applications.
