MP6400DG-12-LF-Z Equivalent & Substitute Parts

Part Overview

The MP6400DG-12-LF-Z is a supervisor integrated circuit from Monolithic Power Systems Inc., classified as a Power Management (PMIC) component. This device functions as a simple reset/power-on reset supervisor with open drain or open collector output, designed for single-channel voltage monitoring applications. The part is currently in active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable due to inventory constraints, supply chain disruptions, or manufacturing discontinuation. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct compatibility without circuit redesign.

Substitute Part Grouping Explanation

Substitution eligibility for the MP6400DG-12-LF-Z is determined by strict equivalence across the following critical parameters:

• Manufacturer: Monolithic Power Systems Inc.
• Functional Type: Simple Reset/Power-On Reset Supervisor
• Number of Channels: 1 (single-channel voltage monitoring)
• Voltage Threshold: 1.12V
• Output Type: Open Drain or Open Collector
• Reset Logic: Active Low
• Reset Timeout: Adjustable/Selectable
• Operating Temperature Range: -40°C to 85°C
• Package: 6-VDFN Exposed Pad / 6-QFN (2x2)
• Mounting: Surface Mount
• Compliance: ROHS3 Compliant, REACH Unaffected

The substitute part MP6400DG-12-LF-P meets all these criteria and is therefore classified as a parametric equivalent. The difference between these part numbers relates to packaging format (Tape & Reel designation suffix), not electrical or mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both MP6400DG-12-LF-Z and MP6400DG-12-LF-P are active products with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Inventory availability and lead time requirements
• Packaging format preference (both are supplied in Tape & Reel format with different suffix designations)
• Supply chain logistics and procurement channels
• Current stock levels from authorized distributors

Both parts carry ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The MSL 1 rating indicates unlimited shelf life under standard storage conditions, eliminating moisture-related handling constraints.

Frequently Asked Questions (FAQ)

Q: Can MP6400DG-12-LF-P be used as a direct replacement for MP6400DG-12-LF-Z?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, voltage threshold (1.12V), output configuration (open drain/open collector), reset logic (active low), operating temperature range (-40°C to 85°C), and package type (6-VDFN Exposed Pad, 6-QFN 2x2). No circuit modifications are required.

Q: What is the difference between the -Z and -P suffix designations?

A: The suffix designations relate to packaging format and distribution channel coding from Monolithic Power Systems Inc. Both parts are supplied in Tape & Reel format. The electrical and mechanical specifications are identical.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity rating. Regulatory and environmental certifications are equivalent.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Both parts use the same 6-QFN (2x2) surface mount package with 6-VDFN exposed pad configuration. PCB footprints, solder reflow profiles, and assembly processes are identical.

Q: What inventory considerations should guide part selection?

A: Current stock levels show MP6400DG-12-LF-Z with 1062 pieces and MP6400DG-12-LF-P with 1300 pieces available. Selection should prioritize availability based on project timeline and procurement lead time requirements.
