Substitute Part Grouping Explanation

Substitution for the 5973001007 is based on the following criteria derived from available specifications:

Primary Substitution Basis:

• Manufacturer alignment (Dialight)
• Series continuity (597 series)
• Functional category (LED Indication - Discrete)
• Regulatory compliance (REACH Unaffected, EAR99 classification)
• Moisture sensitivity compatibility (MSL ratings)

The identified substitute part 5973111407F maintains manufacturer and series consistency while providing documented LED indication functionality with specified electrical and optical parameters. This part represents a direct evolution within the product line, offering improved inventory availability and current production status.

Parameter Comparison

Engineering Selection Recommendations

Selection of the 5973111407F as a substitute for the 5973001007 is supported by the following factors:

Regulatory Compliance: Both parts maintain REACH Unaffected status and EAR99 ECCN classification, ensuring equivalent regulatory standing. The substitute part carries ROHS3 compliance certification, providing additional environmental compliance documentation.

Product Line Continuity: Both components belong to the Dialight 597 series and serve identical functional categories as discrete LED indication devices. This series alignment ensures design compatibility within legacy systems.

Inventory Availability: The substitute part 5973111407F maintains significantly higher inventory levels (6246 pcs) compared to the main part (743 pcs), providing improved supply chain reliability.

Moisture Sensitivity Consideration: The main part specifies MSL 1 (Unlimited), while the substitute specifies MSL 3 (168 Hours). Applications requiring unlimited moisture exposure should account for this specification difference during integration planning.

Frequently Asked Questions (FAQ)

Q: Can the 5973111407F directly replace the 5973001007 in all applications?

A: Both parts are Dialight 597 series discrete LED indication components with equivalent regulatory status (REACH Unaffected, EAR99). However, the substitute part specifies MSL 3 (168 Hours) versus the main part's MSL 1 (Unlimited). Applications with extended moisture exposure requirements should evaluate this difference. The substitute part provides documented electrical parameters (1.7V forward voltage, 20mA test current, 33.6mcd brightness) suitable for standard LED indication circuits.

Q: What is the package difference between these parts?

A: The main part 5973001007 does not specify package details in available documentation. The substitute part 5973111407F is specified as 1206 (3016 Metric) surface mount package with dimensions of 3.00mm L x 1.50mm W and maximum height of 1.51mm. Mechanical compatibility must be verified against the original application's PCB layout and assembly specifications.

Q: Are there compliance differences between the parts?

A: Both parts maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99). The substitute part includes ROHS3 compliance certification, which the main part does not specify. This additional certification may be beneficial for applications subject to RoHS requirements.

Q: What optical specifications should I consider for substitution?

A: The substitute part 5973111407F specifies red color (647nm dominant wavelength, 660nm peak wavelength) with 33.6mcd brightness and 70° viewing angle. These parameters define the optical output characteristics. The main part does not provide equivalent optical specifications in available documentation, requiring application-level verification of color and brightness compatibility.

Q: How does the MSL rating affect component handling?

A: MSL 1 (Unlimited) indicates no moisture sensitivity restrictions during storage and handling. MSL 3 (168 Hours) specifies a maximum of 168 hours of exposure to 30°C/60% RH conditions before soldering. Applications with extended pre-assembly storage periods should account for this difference in component preparation procedures.
