Key Parameters

Substitute Part Grouping Explanation

Substitution of the CEA-13-250UR-350 is determined by the following critical parameters:

Primary Substitution Criteria:

• Pattern Type: Rectangular Rosette configuration for three-axis strain measurement
• Resistance Value: 350 Ohms nominal with ±0.4% tolerance
• Strain Range: ±5% measurement capability
• Active Gauge Dimensions: 0.250" × 0.120" per section
• Operating Temperature Range: -100 ~ 350°F (-75 ~ 175°C)
• Compliance Requirements: RoHS Compliant status

The substitute part MMF404493 maintains functional equivalence through identical pattern type, resistance specification, and environmental operating parameters. The transition from obsolete to active product status ensures continued availability without modification to application-level specifications.

Engineering Selection Recommendations

The MMF404493 serves as the direct substitute for the obsolete CEA-13-250UR-350. Selection is based on the following engineering factors:

Product Status Alignment: The substitute part maintains active product status with Micro-Measurements, ensuring long-term availability and manufacturing consistency compared to the obsolete original part number.

Compliance Continuity: Both parts maintain identical RoHS Compliant certification and Moisture Sensitivity Level 1 (Unlimited) rating, ensuring regulatory and environmental performance equivalence.

Electrical and Mechanical Specifications: The substitute part preserves all critical electrical parameters (350 Ohms resistance, ±5% strain range) and mechanical dimensions required for direct application compatibility.

Series Consistency: Both components belong to the CEA rectangular rosette strain gauge series, confirming design family compatibility and interchangeability within existing measurement systems.

Frequently Asked Questions (FAQ)

Q: Can MMF404493 be used as a direct replacement for CEA-13-250UR-350 in existing applications?

A: Yes. The substitute part maintains identical electrical specifications (350 Ohms, ±5% strain range), mechanical dimensions (0.250" × 0.120" active gauge per section), and environmental ratings (-100 ~ 350°F operating range). Both parts are RoHS Compliant with MSL 1 rating.

Q: What is the primary reason for substitution?

A: The CEA-13-250UR-350 is classified as obsolete. The MMF404493 is an active product from the same manufacturer and series, providing continued supply availability without application-level modifications.

Q: Are there packaging differences between the original and substitute part?

A: The original part packaging is not specified in the technical data. The substitute part MMF404493 is supplied in Bulk packaging. Verify packaging requirements for your specific procurement and handling procedures.

Q: Do both parts have identical resistance tolerance specifications?

A: The resistance tolerance for the original part is specified as ±0.4%. Tolerance specifications for the substitute part are not provided in the available technical data. Confirm tolerance requirements with the manufacturer if precision matching is critical to your application.

Q: Are there any temperature range limitations when substituting?

A: Both parts operate within the identical temperature range of -100 ~ 350°F (-75 ~ 175°C). No temperature-related limitations apply to substitution.
