• Lens Transparency: Clear
• Lens Style: Round with Flat Top
• RoHS Compliance: ROHS3 Compliant

Electrical Operating Parameters:

• Voltage - Forward (Vf): 1.7V to 2.1V range
• Current - Test: 20mA
• Wavelength - Dominant: 640nm to 647nm range

Identified Substitute Parts:

1. 5973111407F (Similar) – Dialight Series 597, identical electrical specifications to main part, alternative packaging (Tape & Reel), Obsolete status
2. 599-0410-122F (MFR Recommended) – Dialight Series 599, Active product status, higher brightness (105mcd), modified package dimensions (3216 Metric), elevated forward voltage (2.1V)

Parameter Comparison

Engineering Selection Recommendations

5973111407F Selection Criteria: This part maintains identical electrical and optical specifications to the 5973111402F, differing only in packaging format (Tape & Reel versus Strip). Both components carry Obsolete product status and ROHS3 compliance. Selection of 5973111407F is appropriate for applications requiring equivalent performance characteristics with alternative supply chain packaging.

599-0410-122F Selection Criteria: This part represents the manufacturer-recommended substitute, carrying Active product status and ROHS3 compliance pathway. Electrical differences include elevated forward voltage (2.1V versus 1.7V) and increased brightness output (105mcd versus 33.6mcd). The viewing angle narrows from 70° to 40°, and package dimensions shift to 3216 Metric specification. Selection of 599-0410-122F is appropriate for new designs or production transitions where increased brightness and narrower viewing angle align with application requirements, and circuit design accommodates the 0.4V forward voltage increase.

Frequently Asked Questions (FAQ)

Q: Can 5973111407F directly replace 5973111402F in existing designs? A: Yes. Both parts share identical electrical specifications (1.7V forward voltage, 20mA test current, 33.6mcd brightness, 647nm wavelength, 70° viewing angle) and mechanical form factor (1206 3016 Metric package). The sole difference is packaging format (Tape & Reel versus Strip). Circuit performance remains unchanged.

Q: What are the key differences between 599-0410-122F and the original 5973111402F? A: Three primary differences exist: forward voltage increases from 1.7V to 2.1V, brightness increases from 33.6mcd to 105mcd, and viewing angle narrows from 70° to 40°. Package dimensions shift from 3016 Metric to 3216 Metric. Circuit design must accommodate the 0.4V voltage increase.

Q: Is 599-0410-122F suitable for designs requiring the original 70° viewing angle? A: No. The 599-0410-122F viewing angle is 40°, compared to 70° for the original part. Applications requiring wide-angle light distribution should retain 5973111402F or 5973111407F specifications.

Q: What is the product status significance for these parts? A: The 5973111402F and 5973111407F carry Obsolete status, indicating discontinued manufacturing. The 599-0410-122F carries Active status, indicating current production availability and long-term supply continuity.

Q: Are all three parts RoHS3 compliant? A: The 5973111402F and 5973111407F are explicitly ROHS3 Compliant. RoHS status for 599-0410-122F is not specified in available documentation.

Q: Can these parts be used interchangeably in automated assembly? A: 5973111402F and 5973111407F are mechanically interchangeable in automated pick-and-place equipment, differing only in supply packaging format. The 599-0410-122F requires equipment recalibration due to package dimension changes (3016 to 3216 Metric).
