Key Parameters

Substitute Part Grouping Explanation

Substitution of the CEA-00-250UR-350 is determined by the following critical parameters:

Primary Substitution Criteria:

• Series designation (CEA)
• Pattern type (Rectangular Rosette)
• Strain range (±5%)
• Resistance value (350 Ohms)
• Active dimensions (0.250" length × 0.120" width)
• Operating temperature range (-100 ~ 350°F)
• Compliance certifications (RoHS Compliant, MSL 1)

The substitute part MMF404491 maintains compatibility across these core parameters, enabling direct functional replacement in applications requiring rectangular rosette strain gauge configurations with the specified electrical and thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MMF404491 serves as the direct equivalent for the obsolete CEA-00-250UR-350. Both components are manufactured by Micro-Measurements and share identical electrical specifications, dimensional characteristics, and compliance certifications. The primary distinction is product status: MMF404491 maintains active production status, ensuring availability and supply chain continuity.

Selection of MMF404491 is appropriate for applications requiring rectangular rosette strain gauge functionality with 350 Ohms resistance, ±5% strain measurement capability, and operation within the -100 ~ 350°F temperature envelope. Both parts maintain RoHS compliance and MSL 1 moisture sensitivity classification, supporting equivalent reliability and environmental performance.
