Substitute Part Grouping Explanation

Substitute parts for the 5636D1 are identified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Substitution Criteria:

• Single red LED configuration
• Through-hole, right-angle mounting type
• Rectangular flat-top lens style
• Operating current of 20mA
• Voltage rating within acceptable operating range (2.0V to 2.1V)
• Red color spectrum (wavelength 635nm to 700nm)
• ROHS3 compliance and REACH unaffected status
• MSL rating of 1 (Unlimited)

The Dialight 5660406F meets these core substitution parameters, maintaining electrical compatibility and mechanical form factor suitability for applications originally designed for the 5636D1.

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5660406F serves as a direct substitute for the obsolete VCC 5636D1 based on the following engineering factors:

Electrical Compatibility: Both components operate at 20mA current with voltage ratings of 2.0V to 2.1V, ensuring compatibility with existing circuit designs. The 5660406F operates at 2.0V, which is within the acceptable range for applications designed for the 2.1V 5636D1.

Mechanical Compatibility: Both parts feature identical mounting configurations (through-hole, right-angle) and matching lens styles (rectangle with flat top), enabling direct physical substitution in PCB layouts without modification.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements. MSL ratings are identical at Level 1 (Unlimited), indicating equivalent moisture sensitivity handling.

Product Availability: The 5660406F carries Active product status with 2200 units in stock, providing reliable supply chain continuity compared to the Obsolete 5636D1 status.

Optical Characteristics: The 5660406F provides higher brightness output (7.4mcd versus 4mcd) with a 140° viewing angle specification. The wavelength difference (635nm versus 700nm) represents a shift within the red spectrum; both wavelengths are perceptually red to the human eye.

Frequently Asked Questions (FAQ)

Q: Can the Dialight 5660406F directly replace the VCC 5636D1 in existing designs?

A: Yes. Both components share identical mounting type (through-hole, right-angle), lens style (rectangle with flat top), current rating (20mA), and voltage operating range (2.0V to 2.1V). No PCB layout modifications are required.

Q: What is the difference in wavelength between these two parts?

A: The 5636D1 operates at 700nm peak wavelength, while the 5660406F operates at 635nm. Both wavelengths fall within the red spectrum. The 635nm wavelength is classified as red-orange, while 700nm is deep red. Visual perception of both colors will appear red in typical circuit board indicator applications.

Q: Why does the 5660406F have higher brightness than the 5636D1?

A: The 5660406F is rated at 7.4mcd compared to the 5636D1 at 4mcd. This increased brightness output is a characteristic of the Dialight component design and does not prevent substitution. Applications requiring the original brightness level should account for this difference in circuit design if necessary.

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

A: No. Both components are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings of Level 1 (Unlimited). They meet equivalent environmental and regulatory standards.

Q: What is the viewing angle difference?

A: The 5660406F specifies a 140° viewing angle. The 5636D1 does not provide a viewing angle specification in the available data. The 140° specification for the 5660406F indicates a wide viewing angle suitable for general indicator applications.

Q: Is the lens type difference significant?

A: The 5636D1 features a tinted lens, while the 5660406F features a diffused, tinted lens. The diffused lens on the 5660406F provides broader light distribution, which is compatible with applications originally designed for the tinted lens of the 5636D1.

Q: What is the packaging difference?

A: The 5636D1 is listed with packaging designation "-" (not specified), while the 5660406F is supplied in Bulk packaging. Both are through-hole components suitable for standard PCB assembly processes.
