EA-06-062TV-350/E Strain Gauge Equivalent & Substitute Parts

Part Overview

The MMF001246 (EA-06-062TV-350/E) is a shear/torque strain gauge manufactured by Micro-Measurements, a division of Vishay Precision Group. This component is classified as obsolete, indicating it is no longer in active production. The gauge is designed for shear and torque measurement applications with a strain range of ±3% and 350 Ohms resistance.

Due to its obsolete status, locating original stock may present supply chain challenges. Identifying qualified substitute components ensures design continuity and maintains measurement accuracy in applications requiring shear/torque strain measurement capabilities.

Substitute Part Grouping Explanation

Substitution eligibility for the EA-06-062TV-350/E is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Pattern Type: Shear/Torque configuration
• Strain Range: ±3%
• Resistance: 350 Ohms
• Resistance Tolerance: ±0.2%
• Active Length: 0.062" (1.57mm)
• Active Width: 0.055" (1.40mm)
• Operating Temperature Range: -100 ~ 350°F (-75 ~ 175°C)
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part MMF404391 (EA-06-062TVA-350/E) maintains identical electrical and mechanical specifications to the original component. The primary distinction is product status: MMF404391 is classified as active production, ensuring ongoing availability and supply chain reliability. Both components belong to the EA series from Micro-Measurements and are functionally equivalent for shear/torque measurement applications.

Engineering Selection Recommendations

Primary Selection: MMF404391 (EA-06-062TVA-350/E)

The MMF404391 is the direct functional equivalent of the obsolete MMF001246. Selection of MMF404391 is based on the following engineering criteria:

1. Product Status: MMF404391 maintains active production status, ensuring reliable long-term supply availability and consistent manufacturing quality control.

2. Electrical Equivalence: Identical resistance (350 Ohms), resistance tolerance (±0.2%), and strain range (±3%) ensure direct substitution without circuit redesign or calibration adjustment.

3. Mechanical Equivalence: Active dimensions (0.062" × 0.055"), overall pattern dimensions (0.175" × 0.115"), and overall envelope (0.27" × 0.21") are identical, permitting direct physical replacement in existing mounting configurations.

4. Environmental Specifications: Matching operating temperature range (-100 ~ 350°F / -75 ~ 175°C) and MSL rating (1 - Unlimited) confirm compatibility with the original application environment.

5. Compliance: Both components carry identical ECCN (EAR99) and HTSUS (9031.80.8085) classifications, maintaining regulatory consistency.

Packaging Consideration: MMF404391 is supplied in bulk packaging, whereas the original part packaging specification is not provided. Verify bulk packaging compatibility with your procurement and assembly processes.
