SY88822VKI Equivalent & Substitute Parts

Part Overview

The SY88822VKI is a laser driver IC designed for fiber optic applications, delivering 155 Mbps data rate with single-channel operation. The device supports dual voltage supply ranges (3V to 3.6V and 4.5V to 5.5V) and is packaged in a 10-MSOP surface mount configuration. The SY88822VKI is currently discontinued at DiGi Electronics, making identification of equivalent substitute parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SY88822VKI is determined by strict equivalence across the following electrical and mechanical parameters:

• Data rate specification (155 Mbps)
• Single-channel laser driver architecture
• Dual voltage supply range compatibility (3V ~ 3.6V and 4.5V ~ 5.5V)
• Supply current and modulation current ratings (25 mA and 30 mA respectively)
• Operating temperature range (-40°C ~ 85°C)
• Package configuration (10-MSOP surface mount)
• Moisture sensitivity level (MSL 1)

The SY88822VKG meets all these criteria and is identified as a direct substitute. Both parts share the same base product number (SY88822) and are manufactured by Microchip Technology.

Parameter Comparison

Engineering Selection Recommendations

The SY88822VKG is the direct equivalent substitute for the discontinued SY88822VKI. Both parts are manufactured by Microchip Technology and maintain identical electrical specifications and package configurations.

The primary distinction between the two parts is product status and regulatory compliance. The SY88822VKI is discontinued and carries RoHS non-compliant status, while the SY88822VKG is an active product with ROHS3 compliance. For new designs or production continuity, the SY88822VKG is the appropriate selection.

Packaging format differs between the two parts: the SY88822VKI is supplied in bulk, while the SY88822VKG is supplied in tube format. This distinction affects handling and inventory management but does not impact electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the SY88822VKG be used as a direct replacement for the SY88822VKI?

A: Yes. The SY88822VKG is a direct equivalent substitute. Both parts share identical electrical specifications, including data rate (155 Mbps), voltage supply ranges (3V ~ 3.6V and 4.5V ~ 5.5V), current ratings, operating temperature range, and 10-MSOP package configuration. No circuit modifications are required.

Q: What is the difference between the SY88822VKI and SY88822VKG?

A: The primary differences are product status and regulatory compliance. The SY88822VKI is discontinued and RoHS non-compliant, while the SY88822VKG is an active product with ROHS3 compliance. Additionally, the SY88822VKI is supplied in bulk packaging, while the SY88822VKG is supplied in tube packaging.

Q: Are there any pin configuration differences between these parts?

A: No. Both the SY88822VKI and SY88822VKG use the same 10-MSOP package with identical pin assignments and electrical characteristics.

Q: What is the moisture sensitivity level for these laser driver ICs?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Why is the SY88822VKI discontinued?

A: The SY88822VKI is discontinued at DiGi Electronics. The SY88822VKG remains in active production as the current equivalent offering from Microchip Technology.
