Substitute Part Grouping Explanation

Substitution eligibility for the EA-06-031EC-350 strain gauge is determined by the following critical parameters:

Primary Substitution Criteria:

• Manufacturer: Micro-Measurements (Division of Vishay Precision Group)
• Series: EA
• Pattern Type: Linear
• Strain Range: ±3%
• Resistance: 350 Ohms
• Resistance Tolerance: ±0.2%
• Active Dimensions: 0.031" length × 0.062" width
• Operating Temperature Range: -100 ~ 350°F (-75 ~ 175°C)
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part MMF404442 maintains compatibility within the EA series family and preserves the critical electrical and mechanical specifications required for direct replacement in existing applications. The transition from obsolete to active product status ensures continued manufacturing support and supply availability.

Engineering Selection Recommendations

For New Designs: Select MMF404442 as the primary component choice. This substitute part carries active product status from Micro-Measurements, ensuring ongoing manufacturing support, technical documentation availability, and supply chain reliability. The active status eliminates obsolescence risk and provides access to current quality assurance protocols.

For Existing Inventory Management: The MMF000471 remains available with 848 units in current stock. This inventory may be utilized for near-term production requirements or maintenance applications. However, transition planning to MMF404442 is recommended to prevent supply disruption.

Compliance Considerations: Both parts maintain Moisture Sensitivity Level 1 (Unlimited) classification, indicating no moisture-related handling restrictions. The ECCN classification (EAR99) and HTSUS code (9031.80.8085) apply to the main part; verify current regulatory classifications for the substitute part in your specific application jurisdiction.

Frequently Asked Questions (FAQ)

Q: Can MMF404442 be used as a direct replacement for MMF000471 in existing circuit designs?

A: MMF404442 is designated as a substitute part within the EA series family. Both components share the same manufacturer, series designation, and pattern type. Verify that the electrical specifications (strain range, resistance value, and tolerance) of MMF404442 match your application requirements before implementation.

Q: What is the primary reason for seeking substitute parts for the EA-06-031EC-350?

A: The MMF000471 carries an obsolete product status. Substitute parts ensure continued availability and manufacturing support for applications requiring this strain gauge specification.

Q: Are there packaging differences between the main part and substitute?
