LED Circuit Board Indicator 5612201802F Equivalent & Substitute Parts

Part Overview

The Dialight 5612201802F is an LED Circuit Board Indicator (CBI) designed for through-hole mounting applications. This single green diffused LED operates at 2V with a 20mA current rating and delivers 32 millicandela brightness. The component features a 5.00mm diameter round lens with domed top and a 60° viewing angle. The part is currently active in production with full ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when inventory constraints or application-specific requirements necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5612201802F is determined by strict alignment of core electrical and mechanical parameters. The following criteria establish compatibility:

Critical Parameters for Substitution:

• Voltage Rating: 2V (exact match required)
• Current: 20mA (exact match required)
• Color: Green (exact match required)
• Wavelength - Peak: 565nm (exact match required)
• Configuration: Single (exact match required)
• Mounting Type: Through Hole (exact match required)
• Base Product Number: 5612201 (same family)
• RoHS Status: ROHS3 Compliant (compliance maintained)

Allowable Parameter Variations:

• Viewing Angle: May vary within optical design constraints
• Lens Style: May differ based on mechanical design
• Lens Size: May vary if mounting compatibility is maintained
• Millicandela Rating: May vary within brightness tolerance specifications

The substitute part 5612201070F meets all critical electrical parameters and maintains the same base product family designation, establishing direct substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 5612201802F and 5612201070F are active production components manufactured by Dialight within the 561 series. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), meeting regulatory requirements for industrial and commercial applications.

The primary distinction between these parts is the viewing angle specification: the main part provides 60° viewing angle while the substitute provides 50° viewing angle. This parameter difference reflects optical design variations within the same brightness and wavelength classification. All other electrical characteristics, including voltage, current, color, and wavelength, are identical.

Selection between these parts should be based on application-specific viewing angle requirements. The 60° viewing angle of the 5612201802F provides broader light distribution, while the 50° viewing angle of the 5612201070F provides more concentrated light output. Both parts are suitable for circuit board indicator applications where through-hole mounting and 2V/20mA operation are specified.

Frequently Asked Questions (FAQ)

Q: Can the 5612201070F directly replace the 5612201802F in existing designs?

A: Direct replacement is possible from an electrical standpoint, as both parts share identical voltage (2V), current (20mA), color (green), and wavelength (565nm) specifications. However, the viewing angle difference (60° vs. 50°) may affect light distribution in the application. Verify that the narrower 50° viewing angle of the substitute meets your optical requirements before implementation.

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

A: Both parts maintain identical compliance status: ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating. No compliance differences exist between the main part and substitute.

Q: What is the significance of the lens style difference between these parts?

A: The main part specifies a round lens with domed top (5.00mm diameter), while the substitute does not specify lens style details. Both parts maintain the same diffused lens type and through-hole mounting configuration. Mechanical fit should be verified for your specific PCB design.

Q: How do the millicandela ratings compare?

A: Both parts deliver identical 32 millicandela brightness output, ensuring consistent indicator visibility in circuit board applications.

Q: Are there inventory considerations for selecting between these parts?

A: The 5612201070F has significantly higher inventory availability (3077 pcs) compared to the 5612201802F (740 pcs). If supply chain continuity is a consideration, the substitute part offers greater stock availability.
