Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Dialight 5973029207F are identified based on the following critical parameters:

• Color and Wavelength: Red spectrum LEDs with dominant wavelength between 624nm and 625nm
• Package Configuration: 4-PLCC or equivalent 4-SMD J-Lead surface mount packages
• Electrical Characteristics: Forward voltage (Vf) range 2.15V to 2.4V; test current 50mA
• Optical Performance: Millicandela rating 1600mcd to 1800mcd; viewing angle 120°
• Mechanical Compatibility: Lens style round with flat top; physical dimensions within 3.20mm L x 2.70mm to 3.20mm L x 2.80mm W; height 1.95mm to 2.10mm
• Regulatory Compliance: ROHS3 compliant; REACH unaffected status

The TT Electronics / Optek Technology OVSA1SBC2R8 meets these substitution criteria with compatible electrical performance, optical characteristics, and mechanical form factor suitable for 4-PLCC applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Dialight 5973029207F and TT Electronics / Optek Technology OVSA1SBC2R8 maintain active product status with ROHS3 compliance and REACH unaffected regulatory standing. The substitute part operates at a higher forward voltage (2.4V versus 2.15V) and delivers slightly lower luminous intensity (1600mcd versus 1800mcd), with wavelength separation of 1nm within the red spectrum. Physical dimensions are compatible with 4-PLCC footprints, with the substitute part measuring 0.1mm narrower and 0.15mm shorter in maximum height. Both components are rated for 50mA test current and 120° viewing angle with identical lens geometry. Component selection should account for circuit voltage tolerance and luminous intensity requirements specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the OVSA1SBC2R8 directly replace the Dialight 5973029207F in existing PCB designs?

A: The OVSA1SBC2R8 is mechanically and electrically compatible with 4-PLCC footprints. The substitute part's forward voltage of 2.4V versus 2.15V requires verification that the driving circuit can accommodate the voltage differential. The 200mcd reduction in luminous intensity should be evaluated against application brightness requirements.

Q: What are the key differences between these two red LEDs?

A: The primary differences are forward voltage (2.15V versus 2.4V), luminous intensity (1800mcd versus 1600mcd), and physical height (2.10mm versus 1.95mm). Wavelength separation is minimal at 1nm (625nm versus 624nm). Both components share identical package configuration, viewing angle, and lens style.

Q: Are there moisture sensitivity considerations for substitution?

A: The Dialight 5973029207F carries MSL 2 (1 Year) rating, while the OVSA1SBC2R8 carries MSL 5A (24 Hours). The substitute part requires shorter storage and handling windows before reflow soldering. Moisture sensitivity level differences should be factored into component procurement and assembly scheduling.

Q: Do both parts meet the same regulatory compliance standards?

A: Both components are ROHS3 compliant and REACH unaffected. ECCN and HTSUS classifications are identical (EAR99 and 8541.41.0000 respectively), confirming equivalent regulatory standing for export and trade purposes.
