Frequently Asked Questions (FAQ)

Q: Why is the CEA-05-250UW-350 classified as obsolete?

A: The CEA-05-250UW-350 has reached end-of-life status in the manufacturer's product portfolio. Micro-Measurements has transitioned production to the CEA-05-250UWA-350, which maintains the same core electrical and mechanical specifications while offering improved compliance certifications.

Q: What are the critical parameters for substitution compatibility?

A: Substitution compatibility is determined by: (1) Resistance value of 350 Ohms, (2) Active dimensions of 0.250" length and 0.180" width, (3) Strain range of ±5%, (4) Manufacturer origin from Micro-Measurements, and (5) Compliance with RoHS and MSL 1 standards.

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

A: The active dimensions (0.250" × 0.180") remain identical. The substitute part specifies overall pattern and overall dimensions: Overall Pattern Length 0.450" (11.43mm), Overall Length 0.55" (14.0mm), Overall Pattern Width 0.180" (6.9mm), and Overall Width 0.27" (6.9mm). These overall dimensions do not affect functional compatibility in standard mounting configurations.

Q: What is the resistance tolerance specification for the substitute part?

A: The CEA-05-250UWA-350 substitute specifies a resistance tolerance of ±0.3%, providing tighter tolerance control compared to the original part specification.

Q: Does the substitute part support the same operating temperature range?

A: The substitute part operates across -103 ~ 347°F (-75 ~ 175°C), providing comprehensive temperature coverage for industrial and laboratory strain measurement applications.

Q: What packaging format is used for the substitute part?

A: The CEA-05-250UWA-350 is supplied in Bulk packaging, suitable for integration into production assembly processes and component kitting operations.

Q: Are there any compliance differences between the original and substitute parts?

A: The substitute part meets ROHS3 Compliant requirements, representing an advancement from the original RoHS Compliant specification. Both parts maintain identical ECCN (EAR99) and HTSUS (9031.80.8085) classifications, ensuring regulatory consistency.

Q: Is the substitute part available in sufficient quantity for production requirements?

A: Current inventory status shows 884 Pcs New Original In Stock for the CEA-05-250UWA-350, providing adequate supply for standard production volumes and procurement planning.
