Substitute Part Grouping Explanation

Substitution of the C2A-06-250LW-120 strain gauge is determined by the following critical parameters:

Primary Substitution Criteria:

• Manufacturer: Micro-Measurements (Division of Vishay Precision Group)
• Pattern Type: Linear
• Resistance: 120 Ohms
• Strain Range: ±3%
• Active Length: 0.250" (6.35mm)
• Active Width: 0.100" (2.54mm)
• Operating Temperature Range: -60 ~ 180°F (-50 ~ 80°C)
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part MMF404428 (C4A-06 LINEAR) is identified as the manufacturer-recommended equivalent. Both components are produced by Micro-Measurements and share the same linear pattern type and MSL classification. The C4A-06 series represents the active product line successor to the obsolete C2A series.
