SY88822VKC Equivalent & Substitute Parts

Part Overview

The SY88822VKC is a laser driver IC designed for fiber optic applications, delivering 155Mbps data rate performance in a compact 10-MSOP surface mount package. This component supports dual voltage supply ranges (3V–3.6V and 4.5V–5.5V) and is classified as a single-channel laser diode driver. The SY88822VKC is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing design support and production continuity.

Substitute Part Grouping Explanation

The SY88822VKG qualifies as a direct substitute for the SY88822VKC based on identical electrical and mechanical parameters. Substitution eligibility is determined by the following criteria:

• Data rate: 155 Mbps (identical)
• Channel configuration: 1 channel (identical)
• Voltage supply ranges: 3V–3.6V and 4.5V–5.5V (identical)
• Supply current: 25 mA (identical)
• Modulation current: 30 mA (identical)
• Operating temperature range: −40°C to +85°C (identical)
• Package and pinout: 10-MSOP (identical)
• Mounting type: Surface Mount (identical)

The primary difference between these parts is packaging format (Bulk vs. Tube) and product status (Discontinued vs. Active).

Parameter Comparison

Engineering Selection Recommendations

The SY88822VKG is the appropriate substitute for the discontinued SY88822VKC. Both parts are manufactured by Microchip Technology and share identical electrical specifications and package geometry, ensuring direct functional compatibility in existing circuit designs.

The SY88822VKG offers the additional advantage of active product status and ROHS3 compliance, making it suitable for new designs and applications with environmental or regulatory requirements. The SY88822VKG is currently available in higher inventory quantities (2479 units) compared to the SY88822VKC (930 units).

Frequently Asked Questions (FAQ)

Q: Can the SY88822VKG replace the SY88822VKC in existing designs?

A: Yes. Both parts are electrically and mechanically identical, with matching data rates (155 Mbps), voltage supply ranges (3V–3.6V and 4.5V–5.5V), current specifications, operating temperature ranges, and 10-MSOP package geometry. No circuit modifications are required.

Q: What is the difference between Bulk and Tube packaging?

A: Bulk and Tube refer to order and handling formats. Bulk packaging is typically used for smaller quantities or inventory management, while Tube packaging is standard for production orders. Both formats contain the same component with identical electrical and mechanical properties.

Q: Does the RoHS compliance difference affect substitution?

A: The SY88822VKG is ROHS3 compliant, while the SY88822VKC is non-compliant. For applications subject to environmental or regulatory requirements, the SY88822VKG is the required choice. For legacy systems without such constraints, both parts are functionally equivalent.

Q: Are the pinouts identical between these parts?

A: Yes. Both the SY88822VKC and SY88822VKG use the 10-MSOP package with identical pinout and pin assignments. Direct PCB compatibility is confirmed.

Q: What is the operating temperature range for both parts?

A: Both parts operate across −40°C to +85°C, supporting industrial and commercial temperature environments.
