Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5655F7 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

• Voltage Rating: 2.1V
• Current Rating: 10mA
• Wavelength - Peak: 585nm (yellow spectrum)
• Millicandela Rating: 6.3mcd

Mechanical Compatibility:

• Lens Size: 3mm, T-1
• Lens Style: Round with Domed Top
• Mounting Type: Through Hole, Right Angle
• Configuration: Single

Regulatory & Environmental:

• RoHS3 Compliance
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status

The substitute part 5510307F from Dialight meets all critical electrical and mechanical parameters while maintaining full regulatory compliance. The primary distinction is the lens type classification (Diffused, Tinted versus Tinted), which does not affect electrical performance or mechanical fit. The substitute part carries Active product status, ensuring long-term availability.
