MIC2550ABTS Equivalent & Substitute Parts

Part Overview

The MIC2550ABTS is a half-duplex USB 2.0 transceiver IC manufactured by Microchip Technology, housed in a 14-TSSOP surface mount package. This component is designed for interface applications requiring single-channel transceiver functionality at USB 2.0 data rates. The MIC2550ABTS 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 MIC2550ABTS is determined by strict equivalence across the following critical parameters:

• Protocol specification: USB 2.0
• Transceiver configuration: 1/1 (single driver/receiver pair)
• Duplex mode: Half-duplex operation
• Data rate capability: 12 Mbps minimum
• Supply voltage range: 4V ~ 5.25V
• Package type: 14-TSSOP surface mount
• Receiver hysteresis: 200 mV
• Operating temperature range: -40°C ~ 85°C

The MIC2550AYTS meets all these parameters and qualifies as a parametric equivalent. The primary distinction between these parts is product status and compliance certification, not functional or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MIC2550AYTS is the direct parametric equivalent for the discontinued MIC2550ABTS. All electrical and mechanical specifications are identical, ensuring functional interchangeability in circuit designs.

The MIC2550AYTS offers additional advantages for new designs and production continuity:

• Active product status ensures ongoing availability and manufacturer support
• ROHS3 compliance meets current environmental and regulatory requirements
• Tube packaging is standard for production environments

The MIC2550ABTS, while RoHS non-compliant, may remain suitable for legacy systems or applications where RoHS compliance is not mandated. However, for new designs or systems requiring regulatory compliance, the MIC2550AYTS is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the MIC2550AYTS directly replace the MIC2550ABTS in existing designs?

A: Yes. The MIC2550AYTS is electrically and mechanically equivalent to the MIC2550ABTS. All functional parameters, including protocol, data rate, supply voltage, operating temperature, and package specifications, are identical. No circuit modifications are required.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and compliance certification. The MIC2550ABTS is discontinued, while the MIC2550AYTS is active. The MIC2550AYTS is ROHS3 compliant, whereas the MIC2550ABTS is RoHS non-compliant. Packaging differs: MIC2550AYTS is supplied in tubes.

Q: Are there any pin configuration differences?

A: No. Both parts use the 14-TSSOP package with identical pin assignments and electrical characteristics.

Q: Which part should be specified for new designs?

A: The MIC2550AYTS should be specified for new designs. It is actively manufactured, meets current compliance standards, and ensures long-term availability.

Q: Is the 200 mV receiver hysteresis specification critical for substitution?

A: Yes. The receiver hysteresis specification defines the input threshold characteristics of the transceiver. Both parts maintain this specification, confirming functional equivalence.

Q: Can the MIC2550AYTS be used in applications requiring RoHS non-compliance?

A: The MIC2550AYTS is ROHS3 compliant and does not meet RoHS non-compliance requirements. If RoHS non-compliance is a specific design requirement, the MIC2550ABTS would be necessary, though availability is limited due to discontinued status.
