Key Parameters

Substitute Part Grouping Explanation

Substitution of strain gauges is determined by compatibility across the following critical parameters:

Primary Substitution Criteria:

• Manufacturer: Micro-Measurements (same manufacturer ensures design compatibility)
• Pattern Type: Linear (functional geometry requirement)
• Resistance Value: 350 Ohms (electrical circuit matching)
• Strain Range: ±3% (measurement capability requirement)
• Active Dimensions: 0.250" length × 0.100" width (physical fit and sensitivity)
• Resistance Tolerance: ±0.6% (measurement accuracy specification)
• Operating Temperature Range: -60 ~ 180°F (-50 ~ 80°C) (environmental compatibility)
• Moisture Sensitivity Level: 1 (Unlimited) (storage and handling compatibility)

The substitute part MMF404145 (C4A-06 Linear Strain Gauge) is identified from the manufacturer's active product line. Substitution eligibility is based on matching the electrical and mechanical parameters specified for the C2A-06-250LW-350 within the allowed tolerances for this product category.

Engineering Selection Recommendations

The MMF404145 (C4A-06 Linear Strain Gauge) is identified as the manufacturer-recommended substitute for the obsolete MMF307481 (C2A-06-250LW-350). This substitution is based on the following engineering factors:

Product Status Consideration: The original part is classified as obsolete, while the substitute part maintains active product status within the Micro-Measurements catalog, ensuring long-term availability and continued manufacturing support.

Compliance and Certification: The substitute part is RoHS Compliant, meeting current regulatory requirements for electronic components in regulated markets and applications.

Manufacturer Continuity: Both parts are manufactured by Micro-Measurements (Division of Vishay Precision Group), ensuring design philosophy consistency and technical support alignment.

Functional Compatibility: Both parts are linear pattern strain gauges with matching Moisture Sensitivity Level (MSL) classification of 1 (Unlimited), indicating equivalent handling and storage requirements.

Component selection should be based on verification that the substitute part's complete electrical and mechanical specifications align with the application requirements originally specified for the C2A-06-250LW-350.

Frequently Asked Questions (FAQ)

Q: Why is the C2A-06-250LW-350 listed as obsolete?

A: The MMF307481 (C2A-06-250LW-350) has been discontinued by Micro-Measurements and is no longer in active production. The C4A-06 series represents the current generation of equivalent linear strain gauges from the manufacturer.

Q: What are the key compatibility factors when substituting strain gauges?

A: Strain gauge substitution requires matching of pattern type (linear), resistance value (350 Ohms), strain range capability (±3%), active dimensions (0.250" × 0.100"), resistance tolerance (±0.6%), operating temperature range (-60 ~ 180°F), and moisture sensitivity classification (MSL 1).
