MIC2555-0BML-TR Equivalent & Substitute Parts

Part Overview

The MIC2555-0BML-TR is a half-duplex USB 2.0 transceiver IC manufactured by Microchip Technology, housed in a 24-MLF® (4x4) surface mount package. This component functions as a 1/1 transceiver for USB 2.0 interface applications with a 400 kbps data rate and operates across a 3V to 4.5V supply voltage range.

The MIC2555-0BML-TR has been discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MIC2555-0BML-TR is determined by strict equivalence across the following critical parameters:

• Protocol specification (USB 2.0)
• Transceiver configuration (1/1 half-duplex)
• Data rate (400 kbps)
• Receiver hysteresis (200 mV)
• Supply voltage range (3V ~ 4.5V)
• Operating temperature range (-40°C ~ 85°C)
• Package type (24-MLF® with exposed pad)
• Mounting type (Surface Mount)

The MIC2555-0YML-TR meets all these criteria and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The MIC2555-0YML-TR is the direct parametric equivalent for the discontinued MIC2555-0BML-TR. Both parts share identical electrical and mechanical specifications across all critical interface parameters.

The MIC2555-0YML-TR offers additional advantages: it maintains active product status with higher inventory availability (5338 pcs vs. 718 pcs), and achieves ROHS3 compliance compared to the non-compliant status of the original part. The MSL rating difference (3 vs. 2) reflects standard manufacturing variations and does not affect functional compatibility in equivalent operating conditions.

Frequently Asked Questions (FAQ)

Q: Are the MIC2555-0BML-TR and MIC2555-0YML-TR pin-compatible?

A: Yes. Both parts use the identical 24-MLF® (4x4) package with exposed pad configuration, ensuring direct pin-for-pin compatibility in PCB layouts.

Q: Can the MIC2555-0YML-TR replace the MIC2555-0BML-TR in existing designs?

A: Yes. The substitute part maintains all electrical specifications including USB 2.0 protocol, 1/1 half-duplex transceiver configuration, 400 kbps data rate, 200 mV receiver hysteresis, 3V to 4.5V supply voltage range, and -40°C to 85°C operating temperature range.

Q: What is the difference in RoHS compliance between these parts?

A: The MIC2555-0BML-TR is RoHS non-compliant, while the MIC2555-0YML-TR is ROHS3 compliant. This distinction is relevant for applications subject to RoHS regulatory requirements.

Q: Does the MSL rating difference affect component handling?

A: The MIC2555-0YML-TR has MSL 3 (168 hours) compared to MSL 2 (1 year) for the original part. This indicates different moisture sensitivity classifications and may require adjusted storage and handling procedures according to IPC standards.

Q: What is the availability status of the substitute part?

A: The MIC2555-0YML-TR is currently active in production with 5338 pcs in stock, compared to the discontinued status of the MIC2555-0BML-TR.
