Substitute Part Grouping Explanation

Substitution of the CEA-13-250UW-350 is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Manufacturer: Micro-Measurements (Division of Vishay Precision Group)
• Series: CEA
• Pattern Type: Linear
• Strain Range: ±5%
• Resistance: 350 Ohms
• Resistance Tolerance: ±0.3%
• Active Dimensions: 0.250" (6.35mm) length × 0.180" (4.57mm) width
• Operating Temperature Range: -100 ~ 350°F (-75 ~ 175°C)
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part MMF403930 maintains identical electrical and mechanical specifications while transitioning from obsolete to active product status. This substitution preserves all functional characteristics required for direct replacement in existing applications.

Parameter Comparison

Engineering Selection Recommendations

The CEA-13-250UWA-350 (MMF403930) is the direct equivalent substitute for the obsolete CEA-13-250UW-350 (MMF003254). Selection of the substitute part is based on the following engineering factors:

Product Status Transition: The original part is classified as obsolete, while the substitute maintains active product status with Micro-Measurements. This ensures continued availability, technical support, and compliance with current manufacturing standards.

Electrical and Mechanical Equivalence: All critical parameters—resistance value, tolerance, strain range, active dimensions, and operating temperature range—are identical between the original and substitute parts. This equivalence permits direct replacement without circuit redesign or mechanical modification.

Compliance and Certification: Both parts maintain identical Moisture Sensitivity Level (MSL) classification and regulatory designations (ECCN: EAR99; HTSUS: 9031.80.8085), ensuring compliance with existing procurement and export requirements.

Packaging Consideration: The substitute part is supplied in bulk packaging, which may differ from the original packaging specification. Procurement processes should account for this packaging difference when ordering.

Frequently Asked Questions (FAQ)

Q: Can the CEA-13-250UWA-350 (MMF403930) be used as a direct replacement for the CEA-13-250UW-350 (MMF003254)?

A: Yes. The substitute part maintains identical electrical specifications (350 Ohms, ±0.3% tolerance, ±5% strain range), mechanical dimensions (0.250" × 0.180" active area), and operating temperature range (-100 ~ 350°F). Direct substitution is supported without circuit modification.

Q: What is the primary difference between these two parts?

A: The CEA-13-250UW-350 is obsolete, while the CEA-13-250UWA-350 is an active product. The substitute part designation includes the suffix "A" and is supplied in bulk packaging. All functional parameters remain equivalent.

Q: Are there any compatibility concerns with existing designs?

A: No compatibility concerns exist for electrical or mechanical integration. The substitute part maintains all critical parameters required for functional equivalence. Procurement teams should verify packaging requirements, as the substitute is supplied in bulk format.

Q: Does the substitute part meet the same environmental and compliance standards?

A: Yes. Both parts maintain identical Moisture Sensitivity Level (MSL) classification of 1 (Unlimited) and identical regulatory designations (ECCN: EAR99; HTSUS: 9031.80.8085).

Q: What inventory status should be considered for procurement planning?

A: The original CEA-13-250UW-350 has 857 pieces in stock. The substitute CEA-13-250UWA-350 has 1110 pieces in stock. The substitute part offers improved availability as an active product.
