Equivalent & Substitute Parts: MMF003216

Part Overview

The MMF003216 is a rectangular rosette strain gauge manufactured by Micro-Measurements (Division of Vishay Precision Group). This component is part of the CEA series and features a 350 ohm resistance configuration with ±5% strain measurement capability. The part is classified as obsolete, necessitating identification of active equivalent alternatives for ongoing applications and new designs. Substitute parts must maintain functional compatibility across electrical specifications, mechanical dimensions, and environmental operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMF003216 is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value of 350 ohms, resistance tolerance of ±0.4%, and strain range of ±5% must be maintained to ensure signal conditioning compatibility and measurement accuracy in existing instrumentation.

Mechanical Configuration: Pattern type (rectangular rosette), active dimensions per section (0.250" length × 0.120" width), and overall pattern dimensions (0.500" × 0.760") must match to ensure proper mounting and strain field capture characteristics.

Environmental Compliance: Operating temperature range (-100 to 350°F / -75 to 175°C), RoHS compliance status, and moisture sensitivity level (MSL 1) must be preserved for application reliability and regulatory adherence.

Manufacturer Continuity: Parts must originate from Micro-Measurements to maintain consistency with established material properties, adhesive systems, and quality certifications.

The MMF404492 satisfies all substitution criteria as an active product within the same manufacturer portfolio.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The MMF003216 is classified as obsolete, while the MMF404492 maintains active product status. For new designs and ongoing production requirements, the MMF404492 is the appropriate selection to ensure long-term supply chain continuity and manufacturer support.

Compliance Verification: Both parts maintain RoHS compliance and MSL 1 rating, satisfying regulatory requirements for industrial and commercial strain measurement applications. No additional compliance documentation is required for substitution.

Inventory and Availability: The MMF404492 is currently available with 1180 pieces in stock, providing immediate procurement capability. The MMF003216, while currently inventoried at 1140 pieces, represents a declining resource due to obsolescence status.

Direct Substitution: The MMF404492 functions as a direct replacement for the MMF003216 in all applications where the CEA series rectangular rosette strain gauge with 350 ohm resistance is specified. No circuit modifications, recalibration procedures, or application redesign is required.

Frequently Asked Questions (FAQ)

Q: Can the MMF404492 be used as a direct replacement for the MMF003216 in existing assemblies?

A: Yes. Both parts share identical electrical specifications (350 ohms, ±5% strain range), mechanical configuration (rectangular rosette pattern with matching dimensions), and environmental ratings. Direct substitution is supported without modification to mounting, wiring, or signal conditioning circuits.

Q: What is the primary reason for substituting the MMF003216?

A: The MMF003216 is classified as obsolete. The MMF404492 is the active equivalent from Micro-Measurements, ensuring continued availability, manufacturer support, and compliance with current quality standards.

Q: Are there dimensional differences between these parts?

A: The input data for the MMF404492 does not specify dimensional parameters. However, both parts are designated as CEA series rectangular rosette strain gauges with 350 ohm resistance. Confirmation of dimensional equivalence should be obtained from Micro-Measurements technical documentation if precise mechanical compatibility is critical to the application.

Q: Do both parts meet the same environmental specifications?

A: Both parts are RoHS compliant and rated at MSL 1 (unlimited moisture sensitivity level). The MMF003216 specifies an operating temperature range of -100 to 350°F (-75 to 175°C). Environmental specifications for the MMF404492 are not provided in the available data.

Q: What packaging format is the MMF404492 supplied in?

A: The MMF404492 is supplied in bulk packaging. The MMF003216 packaging format is not specified in the available data. Packaging requirements should be confirmed with procurement specifications for your application.

Q: Is recalibration required when switching from MMF003216 to MMF404492?

A: No recalibration is required. Both parts maintain the same resistance value (350 ohms) and resistance tolerance (±0.4%), ensuring equivalent signal output and measurement accuracy in existing instrumentation without adjustment.
