Substitute Part Grouping Explanation

Substitution of the CEA-00-125UR-350 strain gauge is determined by the following critical parameters:

Primary Substitution Criteria:

• Manufacturer: Micro-Measurements (Division of Vishay Precision Group)
• Series compatibility: CEA series
• Resistance value: 350 Ohms
• Resistance tolerance: ±0.4%
• Pattern type: Rectangular Rosette configuration
• Strain range: ±5%
• Physical dimensions: Active length 0.125" (3.18mm) per section; Active width 0.060" (1.52mm) per section
• Operating temperature range: -100 ~ 350°F (-75 ~ 175°C)
• Compliance: RoHS Compliant
• Moisture sensitivity: MSL 1 (Unlimited)

The identified substitute part MMF404270 is manufactured by the same supplier and maintains compatibility within the CEA series strain gauge family. Substitution is valid when the replacement component meets or exceeds all specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The CEA-00-125UR-350 (MMF003137) is classified as obsolete. The substitute part MMF404270 is an active product from the same manufacturer within the CEA series family. Both components maintain RoHS compliance and MSL 1 rating, ensuring compatibility with modern manufacturing and environmental standards.

Selection of MMF404270 as a substitute is supported by:

• Continued availability from the original manufacturer (Active product status)
• Identical RoHS compliance certification
• Equivalent moisture sensitivity classification
• Same manufacturer lineage ensuring consistent material composition and performance characteristics
• Bulk packaging availability for production requirements

Frequently Asked Questions (FAQ)

Q: Can MMF404270 directly replace CEA-00-125UR-350 in existing applications?

A: MMF404270 is a substitute within the CEA series strain gauge family from Micro-Measurements. Both components share identical RoHS compliance and MSL ratings. Verification of specific electrical and mechanical parameter compatibility with your application requirements is necessary before implementation.

Q: What is the significance of the obsolete status for CEA-00-125UR-350?

A: Obsolete status indicates that the CEA-00-125UR-350 is no longer in active production. Existing inventory may be available, but long-term supply cannot be guaranteed. Transition to active substitute components is recommended for new designs and ongoing production requirements.

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

A: The CEA-00-125UR-350 packaging is not specified in available documentation. The substitute MMF404270 is supplied in bulk packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Do both parts meet current environmental compliance standards?

A: Yes. Both CEA-00-125UR-350 and MMF404270 are RoHS Compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, meeting current environmental and reliability standards.

Q: What parameters must remain constant for substitution validity?

A: Substitution validity depends on maintaining the CEA series designation, 350 Ohm resistance value, ±0.4% resistance tolerance, rectangular rosette pattern type, ±5% strain range, and operating temperature range of -100 ~ 350°F (-75 ~ 175°C).
