MMC5883MA Equivalent & Substitute Parts

Part Overview

The MMC5883MA is a magnetoresistive sensor manufactured by Memsic Inc. designed for three-axis magnetic field measurement with I2C digital output. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for new designs and ongoing production requirements. The sensor operates in the ±0.8mT sensing range with 16-bit resolution and is housed in a 16-LGA (3x3) surface mount package.

Key Parameters

Substitute Part Grouping Explanation

The MMC5983MA qualifies as a direct substitute for the MMC5883MA based on the following critical parameters:

Matching Parameters:

• Manufacturer: Memsic Inc. (same manufacturer ensures design continuity)
• Technology: Magnetoresistive (identical sensing technology)
• Axis Configuration: X, Y, Z (same three-axis measurement capability)
• Sensing Range: ±0.8mT (identical magnetic field measurement range)
• Package Type: 16-VFLGA (3x3) (identical physical footprint and pin configuration)
• Mounting Type: Surface Mount (same PCB assembly method)
• Moisture Sensitivity Level: 3 (168 Hours) (identical handling requirements)

Enhanced Specifications: The MMC5983MA provides improvements in resolution (18-bit versus 16-bit), bandwidth (1kHz versus 600Hz), supply current efficiency (450µA maximum), and extended operating temperature range (-40°C ~ 105°C). The substitute part also offers dual output interface capability (I2C and SPI) compared to the original I2C-only interface.

Parameter Comparison

Engineering Selection Recommendations

The MMC5983MA is the appropriate substitute for the obsolete MMC5883MA. The substitute part maintains identical package geometry, pin configuration, and core magnetic sensing specifications, ensuring direct PCB compatibility without layout modifications.

The MMC5983MA carries Active product status, ensuring long-term availability and supply chain continuity. The part is AEC-Q100 qualified and ROHS3 compliant, meeting automotive and environmental regulatory requirements. The EAR99 ECCN classification provides improved export flexibility compared to the original part's 7A994 classification.

The narrower supply voltage range (2.8V ~ 4.6V versus 2.16V ~ 3.6V) requires verification that existing power supply designs operate within the substitute part's specifications. The increased maximum supply current (450µA versus 120µA) must be evaluated against power budget constraints in the target application.

Frequently Asked Questions (FAQ)

Q: Can the MMC5983MA be used as a direct replacement for the MMC5883MA without PCB modifications?

A: Yes. Both parts use identical 16-VFLGA (3x3) packages with matching pin configurations and footprints. No PCB layout changes are required for physical substitution.

Q: What are the key differences between these two parts?

A: The MMC5983MA provides enhanced resolution (18-bit versus 16-bit), increased bandwidth (1kHz versus 600Hz), extended operating temperature range (-40°C ~ 105°C versus -40°C ~ 85°C), and dual interface support (I2C and SPI versus I2C only). The substitute part has higher maximum supply current (450µA versus 120µA) and a narrower supply voltage operating window (2.8V ~ 4.6V versus 2.16V ~ 3.6V).

Q: Are there firmware or software changes required when switching to the MMC5983MA?

A: The I2C interface remains compatible. Designs using only I2C communication require no firmware modifications. Designs that can leverage the SPI interface or higher resolution may benefit from firmware optimization, but such changes are not mandatory for basic functionality.

Q: What is the supply voltage compatibility consideration?

A: The MMC5983MA operates within 2.8V ~ 4.6V, which is narrower than the original part's 2.16V ~ 3.6V range. Verify that your power supply design maintains voltage within the substitute part's specifications across all operating conditions, including startup transients and load variations.

Q: Is the MMC5983MA suitable for automotive applications?

A: Yes. The MMC5983MA carries AEC-Q100 qualification and is designated for automotive grade applications. The original MMC5883MA does not carry this qualification.

Q: What is the moisture sensitivity level, and what does it mean for handling?

A: Both parts have MSL 3 (168 Hours) rating. This indicates the component can be exposed to ambient conditions (30°C, 60% relative humidity) for up to 168 hours after moisture barrier bag opening before soldering. Proper storage in dry conditions is required to maintain this specification.
