Frequently Asked Questions (FAQ)

Q: Can the Nidec ST-32ETA504 be used as a direct replacement for the TE Connectivity 3213X504M?

A: Yes. The ST-32ETA504 matches all electrical parameters (500 kOhms, 0.125W, ±20% tolerance, ±100ppm/°C temperature coefficient), mechanical specifications (square 0.134" x 0.134" package, J Lead termination, surface mount), and environmental ratings (ROHS3 compliant, MSL 1) of the 3213X504M. No circuit modifications are required.

Q: Are there packaging differences between these parts?

A: The TE Connectivity 3213X504M is supplied in standard packaging, while the Nidec ST-32ETA504 is supplied in Tape & Reel (TR) format. Both components are identical in physical dimensions and electrical characteristics. Tape & Reel packaging is standard for surface mount component distribution and does not affect component performance or PCB assembly compatibility.

Q: What is the significance of the product status difference?

A: The TE Connectivity 3213X504M is classified as obsolete, indicating discontinued production and limited availability. The Nidec ST-32ETA504 is classified as active, confirming current production and reliable supply chain access. This status difference is the primary reason for substitution.

Q: Do both parts have identical compliance certifications?

A: Yes. Both the 3213X504M and ST-32ETA504 are ROHS3 compliant and carry moisture sensitivity level 1 (unlimited). Both are classified under ECCN EAR99 for export control purposes.

Q: Is the cermet resistive material composition identical?

A: Yes. Both components utilize cermet resistive material, ensuring equivalent performance characteristics, temperature stability, and long-term reliability in circuit applications.
