Key Parameters

Substitute Part Grouping Explanation

Substitution of the CEA-00-250UW-350 is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (350 Ohms), resistance tolerance (±0.3%), and strain range (±5%) must be identical to ensure proper signal conditioning and measurement accuracy in existing circuit implementations.

Mechanical Specifications: Active length (0.250" / 6.35mm) and active width (0.180" / 4.57mm) must match exactly to maintain compatibility with substrate mounting patterns and stress distribution characteristics.

Environmental Specifications: Operating temperature range (-100 ~ 350°F / -75 ~ 175°C) and Moisture Sensitivity Level (MSL 1) must be maintained to preserve reliability in the intended application environment.

Manufacturer Consistency: All substitute parts are sourced from Micro-Measurements to ensure manufacturing process consistency and quality standards alignment.

The substitute part MMF403931 satisfies all these criteria while offering the advantage of active product status.

Parameter Comparison

Engineering Selection Recommendations

The CEA-00-250UWA-350 (MMF403931) is the direct equivalent substitute for the obsolete CEA-00-250UW-350 (MMF003238). Both components are manufactured by Micro-Measurements and share identical electrical, mechanical, and environmental specifications.

The primary distinction is product status: MMF403931 maintains active manufacturing status, ensuring long-term availability and supply chain reliability. The obsolete status of MMF003238 indicates discontinued production, making MMF403931 the appropriate selection for new designs and ongoing production requirements.

Both parts carry identical Moisture Sensitivity Level (MSL 1) classification and comply with the same environmental and regulatory standards (ECCN: EAR99; HTSUS: 9031.80.8085).

Frequently Asked Questions (FAQ)

Q: Can CEA-00-250UWA-350 (MMF403931) be used as a direct replacement for CEA-00-250UW-350 (MMF003238)?

A: Yes. All electrical specifications (350 Ohms resistance, ±0.3% tolerance, ±5% strain range), mechanical dimensions (0.250" active length, 0.180" active width), and environmental ratings (-100 ~ 350°F operating temperature, MSL 1) are identical between the two parts.

Q: What is the difference between MMF003238 and MMF403931?

A: The primary difference is product status. MMF003238 is obsolete, while MMF403931 is active. The designation change from CEA-00-250UW-350 to CEA-00-250UWA-350 reflects the active product line variant. All functional and performance characteristics remain equivalent.

Q: Are there packaging differences between these parts?

A: MMF003238 is packaged in standard format, while MMF403931 is supplied in Bulk packaging. Both are suitable for component-level integration; packaging selection depends on procurement and assembly workflow requirements.

Q: Does the active status of MMF403931 affect compatibility?

A: No. Active product status ensures continued manufacturing and supply availability. Electrical and mechanical compatibility with existing designs remains unchanged.

Q: What certifications apply to both parts?

A: Both parts are classified under ECCN: EAR99 and HTSUS: 9031.80.8085, maintaining identical regulatory compliance.
