Part Overview

The 5655F3 is a Circuit Board Indicator (CBI) LED manufactured by Visual Communications Company (VCC). This component is a single amber-colored through-hole LED with right-angle mounting configuration, designed for PCB integration in indicator applications. The part operates at 2.2V with a 10mA current rating and features a 3mm T-1 form factor with a round domed top lens.

The 5655F3 carries an Obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for legacy systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the 5655F3 is based on the following critical parameters that must align between the main part and substitute candidates:

Mandatory Matching Parameters:

• Voltage Rating: 2.2V (circuit compatibility)
• Current Rating: 10mA (power budget compatibility)
• Mounting Type: Through Hole, Right Angle (PCB installation compatibility)
• Lens Size: 3mm, T-1 form factor (physical footprint compatibility)
• Configuration: Single LED (functional equivalence)

Compatible Variation Parameters:

• Color: Amber to Orange (within yellow-orange spectrum; wavelength 600nm–603nm acceptable)
• Millicandela Rating: 7mcd (brightness level; minor variations acceptable within indicator application context)
• Lens Type: Tinted or Diffused (both provide optical filtering; functional equivalence for indication purposes)
• RoHS Status: ROHS3 Compliant (regulatory alignment)

The substitute part 5512507F from Dialight meets all mandatory matching parameters and operates within compatible variation ranges. The shift from amber (603nm) to orange (600nm) represents a minor spectral variation acceptable for general indicator applications where precise color matching is not critical to circuit function.

Engineering Selection Recommendations

Primary Substitute: 5512507F (Dialight)

The 5512507F qualifies as a direct functional substitute for the obsolete 5655F3 based on the following engineering criteria:

1. Electrical Compatibility: Identical voltage (2.2V) and current (10mA) ratings ensure direct circuit compatibility without modification to drive circuitry or current-limiting resistor calculations.

2. Physical Compatibility: Matching 3mm T-1 through-hole right-angle form factor and lens size confirm PCB footprint and mounting hole alignment compatibility.

3. Optical Compatibility: Both components deliver 7mcd brightness. The spectral shift from amber (603nm) to orange (600nm) represents a 3nm variance within the yellow-orange spectrum. For general indicator applications where precise color discrimination is not a functional requirement, this variance is acceptable.

4. Regulatory Compliance: Both parts carry ROHS3 compliance, REACH Unaffected status, and identical ECCN/HTSUS classifications, ensuring equivalent regulatory standing for procurement and deployment.

5. Product Status Alignment: The 5512507F maintains Active product status with confirmed inventory availability (2716 pcs), providing supply chain continuity for the obsolete 5655F3.

6. Moisture and Environmental: Identical MSL 1 (Unlimited) ratings confirm equivalent handling and storage requirements.

Selection Consideration: If the application requires strict amber color matching (603nm) rather than orange (600nm), alternative sourcing from other manufacturers producing amber-spectrum 3mm T-1 through-hole LEDs at 2.2V/10mA specifications should be evaluated. However, for standard indicator applications, the 5512507F substitution is electrically and mechanically sound.

Frequently Asked Questions (FAQ)

Q1: Can the 5512507F directly replace the 5655F3 without PCB modification?

A: Yes. The 5512507F matches all critical parameters: 2.2V voltage, 10mA current, 3mm T-1 through-hole right-angle mounting, and 7mcd brightness. No circuit modifications, resistor recalculations, or PCB layout changes are required. The component installs into the same footprint and operates identically from an electrical standpoint.

Q2: What is the significance of the color change from amber to orange?

A: The wavelength shift from 603nm (amber) to 600nm (orange) represents a 3nm variance within the yellow-orange spectrum. For circuit board indicator applications where the LED serves as a status light or functional indicator, this spectral difference is visually negligible to the human eye. If the application requires strict amber color matching for visual distinction from other indicator colors on the same board, the color variance may be significant and alternative sourcing should be considered.

Q3: Are there any compliance or regulatory differences between the two parts?

A: No. Both the 5655F3 and 5512507F carry identical regulatory classifications: ROHS3 Compliant, REACH Unaffected, EAR99 ECCN, and 8541.41.0000 HTSUS code. They present equivalent compliance standing for procurement, deployment, and end-of-life management.

Q4: What is the difference between "Tinted" and "Diffused, Tinted" lens types?

A: Both lens types incorporate optical filtering (tinting) to produce the amber or orange color. The 5655F3 specifies "Tinted" while the 5512507F specifies "Diffused, Tinted." Diffusion scatters light to broaden the viewing angle, while tinting filters the wavelength. The 5512507F provides a specified 60° viewing angle, whereas the 5655F3 does not specify this parameter. For general indicator applications, both lens treatments are functionally equivalent in terms of color production and light output.

Q5: Is the 5512507F available in sufficient quantity for production?

A: Yes. The 5512507F shows 2716 pcs in new original stock, confirming immediate availability. The 5655F3, marked as Obsolete, shows 686 pcs remaining inventory. For ongoing production or maintenance programs, the 5512507F provides superior supply chain continuity.

Q6: What parameters must match exactly for a substitute to be considered equivalent?

A: For 3mm T-1 through-hole right-angle circuit board indicator LEDs, the following parameters must match exactly: voltage rating (2.2V), current rating (10mA), mounting type (through-hole right-angle), and lens size (3mm T-1). Brightness (millicandela), color (within adjacent spectrum), and lens treatment (tinted vs. diffused) may vary within acceptable ranges for indicator applications. Configuration must remain single-element.

Q7: Can the 5512507F be used in applications requiring precise color matching?

A: The 5512507F is orange (600nm) while the 5655F3 is amber (603nm). If the application uses multiple indicator LEDs of different colors on the same board and relies on color distinction for user interface clarity, the 3nm spectral difference may be visually distinguishable. In such cases, sourcing an amber-spectrum substitute from another manufacturer should be evaluated. For single-color indicator applications, the color variance is not functionally significant.
