Key Parameters

Substitute Part Grouping Explanation

Substitute components for the 5681F1_5 are identified based on the following critical parameters that determine functional and mechanical compatibility:

Mechanical Compatibility Parameters:

• Configuration: 2 High dual-LED arrangement
• Lens Size: 3mm, T-1 form factor
• Mounting Type: Through Hole, Right Angle orientation
• Lens Type: Diffused, Tinted optical characteristics
• Lens Style: Round with Domed Top geometry

Electrical Compatibility Parameters:

• Color Configuration: Green and Red LED combination
• Voltage Rating: Green approximately 2.1V–2.2V; Red approximately 2V
• Current Rating: Operating current within specified range
• Wavelength: Green 562–565nm; Red 635nm

Compliance Parameters:

• RoHS3 Compliance required
• MSL Rating: 1 (Unlimited)

The substitute part 5530121200F from Dialight meets these criteria with allowable variations in current rating (10mA versus 30mA) and millicandela output, which represent design trade-offs rather than incompatibilities.

Engineering Selection Recommendations

Primary Substitute: Dialight 5530121200F

The 5530121200F is the qualified substitute for the obsolete 5681F1_5. Selection is based on the following engineering criteria:

Mechanical Compatibility: Both components share identical form factor, mounting configuration, and optical lens characteristics. Direct mechanical substitution is supported without PCB redesign.

Electrical Compatibility: The substitute operates at 10mA versus the original 30mA specification. This represents a lower power consumption design point. Circuit designs must accommodate this current differential through appropriate current-limiting resistor adjustment. Voltage ratings are within 0.1V tolerance for the green LED and identical for the red LED.

Optical Performance: Green wavelength differs by 3nm (562nm to 565nm), which is imperceptible to human vision. Red wavelength is identical. Green brightness is reduced from 16mcd to 12.6mcd; this reduction must be evaluated against application visibility requirements.

Compliance and Availability: The 5530121200F maintains ROHS3 compliance and MSL-1 rating, ensuring regulatory and environmental compatibility. The substitute is in active production status with documented inventory availability, eliminating supply chain risk associated with the obsolete original component.

Design Consideration: Applications requiring the full 30mA current capability or 16mcd green brightness must conduct functional validation with the lower-current, lower-brightness substitute to confirm performance adequacy.

Frequently Asked Questions (FAQ)

Q: Can the 5530121200F be used as a direct drop-in replacement for the 5681F1_5?

A: Mechanical and mounting compatibility is direct. Electrical compatibility requires circuit evaluation. The substitute operates at 10mA instead of 30mA, necessitating current-limiting resistor recalculation. Optical brightness is reduced for the green LED (12.6mcd versus 16mcd), which must be validated against application requirements.

Q: What is the primary difference between these two components?

A: The primary difference is current rating. The 5681F1_5 operates at 30mA; the 5530121200F operates at 10mA. Secondary differences include green LED brightness (16mcd versus 12.6mcd) and green wavelength (562nm versus 565nm). All other parameters are identical or within tolerance.

Q: Are both components RoHS compliant?

A: Yes. Both the 5681F1_5 and 5530121200F are ROHS3 compliant and carry MSL-1 (Unlimited) moisture sensitivity ratings.

Q: Why is the 5681F1_5 obsolete?

A: The 5681F1_5 is classified as obsolete by the manufacturer. The 5530121200F from Dialight is the active production equivalent, ensuring long-term supply availability.

Q: Does the substitute have a different viewing angle?

A: The 5530121200F specifies a 60° viewing angle. The original 5681F1_5 does not provide a viewing angle specification. Both components use identical diffused, tinted lens geometry, suggesting comparable viewing characteristics.

Q: What packaging is available for the substitute?

A: The 5530121200F is supplied in bulk packaging. The original 5681F1_5 packaging specification is not detailed in available documentation.

Q: Can I use the 5530121200F in high-brightness applications?

A: The 5530121200F green LED output is 12.6mcd compared to the original 16mcd. Applications requiring maximum brightness should evaluate whether this reduction meets visibility requirements. The red LED output is identical at 10mcd.
