C2A-13-125LR-350 Strain Gauge Equivalent & Substitute Parts

Part Overview

The MMF307409 C2A-13-125LR-350 is a rectangular rosette strain gauge manufactured by Micro-Measurements (Division of Vishay Precision Group). This component is classified as obsolete and is used for multi-axis strain measurement applications requiring simultaneous data acquisition across three perpendicular directions.

Due to its obsolete product status, sourcing new units from original manufacturing channels is no longer supported. Identifying functionally equivalent active alternatives is necessary to maintain design continuity and ensure long-term component availability for production and field service applications.

Substitute Part Grouping Explanation

Substitution of the C2A-13-125LR-350 strain gauge is determined by the following critical parameters:

Primary Substitution Criteria:

• Pattern Type: Rectangular Rosette configuration for three-axis strain measurement
• Resistance: 350 Ohms nominal value
• Resistance Tolerance: ±0.6% or tighter
• Active Dimensions: 0.125" length × 0.070" width
• Overall Pattern Dimensions: 0.245" length × 0.415" width
• Strain Range: ±3% or greater
• Operating Temperature Range: -60 to 180°F minimum
• Moisture Sensitivity Level: 1 (Unlimited) or equivalent

Identified Substitute:

The MMF404203 C4A-13 rectangular rosette strain gauge from Micro-Measurements is the manufacturer-recommended substitute. This part maintains the same rectangular rosette pattern configuration and is classified as an active product with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The MMF404203 is the manufacturer-recommended equivalent for the obsolete MMF307409. Both components are manufactured by Micro-Measurements and share the rectangular rosette pattern configuration, which is the primary functional requirement for multi-axis strain measurement applications.

Product Status Advantage:

The MMF404203 is classified as an active product with current manufacturing support and inventory availability (948 pieces in stock). This ensures long-term sourcing capability and eliminates supply chain risk associated with obsolete components.

Compliance Consideration:

The MMF404203 is RoHS Compliant, meeting current environmental and regulatory requirements for electronic components. This compliance status is relevant for applications subject to RoHS directives and similar regulatory frameworks.

Selection Basis:

Component selection should be based on the manufacturer's direct recommendation and the active product status of the MMF404203. The identical MSL rating and rectangular rosette pattern configuration support direct substitution in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the MMF404203 directly replace the MMF307409 in existing designs?
