Substitute Part Grouping Explanation

The Dialight 5972111407F serves as a direct functional equivalent to the 5972111407. Substitution is valid based on the following matching parameters:

• Color: Red
• Lens Transparency: Clear
• Lens Size: 2.00mm x 1.00mm
• Voltage - Forward (Vf) Typical: 1.7V
• Current - Test: 20mA
• Millicandela Rating: 12.4mcd
• Viewing Angle: 130°
• Mounting Type: Surface Mount, Right Angle
• Wavelength - Peak: 660nm
• Package / Case: 2-SMD, No Lead
• Supplier Device Package: 1208
• Size / Dimension: 3.00mm L x 2.00mm W
• Height (Max): 1.00mm

The primary distinction between these parts is packaging format and product status. The 5972111407F is supplied in Tape & Reel (TR) format and maintains Active product status, whereas the original 5972111407 is Obsolete.

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5972111407F is the direct active equivalent for the obsolete 5972111407. All electrical and optical parameters are identical, ensuring functional compatibility in circuit designs. The 5972111407F maintains ROHS3 compliance, whereas the original part is RoHS non-compliant. This compliance improvement makes the 5972111407F suitable for applications subject to RoHS regulations.

The MSL rating differs between the two parts: the original 5972111407 carries MSL 1 (Unlimited), while the 5972111407F carries MSL 3 (168 Hours). This difference reflects standard moisture handling requirements and does not affect electrical performance when proper storage and handling procedures are followed.

For new designs and production continuity, the 5972111407F should be selected due to its Active product status and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the 5972111407F directly replace the 5972111407 in existing designs?

A: Yes. All electrical parameters, optical characteristics, and mechanical dimensions are identical. The parts are functionally interchangeable at the circuit level.

Q: What is the difference between the two part numbers?

A: The primary differences are product status (Obsolete vs. Active), packaging format (Bulk vs. Tape & Reel), RoHS compliance status, and MSL rating. Electrical and optical performance are identical.

Q: Why does the 5972111407F have a higher MSL rating?

A: MSL 3 (168 Hours) is a standard moisture sensitivity classification for this component type. Proper storage in dry conditions or desiccant packaging ensures performance is not affected.

Q: Is the 5972111407F suitable for RoHS-regulated applications?

A: Yes. The 5972111407F is ROHS3 compliant, making it suitable for applications subject to RoHS directives. The original 5972111407 is RoHS non-compliant.

Q: Are there any circuit design changes required when switching from 5972111407 to 5972111407F?

A: No. Identical forward voltage (1.7V), test current (20mA), and all optical parameters eliminate the need for circuit modifications.

Q: What packaging quantities are available for the 5972111407F?

A: The 5972111407F is supplied in Tape & Reel (TR) format, suitable for automated assembly processes.
