Parameter Comparison

Engineering Selection Recommendations

Both FC0402E50R0FST1 and FC0402E50R0BST1 are active production components manufactured by Vishay Dale and maintain full ROHS3 compliance with MSL 1 rating. Selection between these parts depends on application tolerance requirements and packaging logistics:

FC0402E50R0FST1 is suitable for applications where ±1% tolerance meets circuit specifications and Tape & Reel packaging is preferred for automated assembly processes.

FC0402E50R0BST1 is appropriate for precision RF and high-frequency circuits requiring ±0.1% tolerance control. The Cut Tape and Digi-Reel® packaging options provide flexibility for manual assembly or mixed-volume production runs.

Both parts maintain identical electrical performance across the full operating temperature range and deliver equivalent RF performance characteristics for high-frequency applications.

Frequently Asked Questions (FAQ)

Q: Can FC0402E50R0BST1 replace FC0402E50R0FST1 in my circuit?

A: Yes. Both parts share identical resistance value, power rating, package dimensions, operating temperature range, and RF/high-frequency performance characteristics. The FC0402E50R0BST1 provides superior tolerance specification at ±0.1% versus ±1%, making it suitable for precision applications.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging is optimized for high-volume automated assembly with continuous reel feeding. Cut Tape (CT) and Digi-Reel® packaging provide flexibility for lower-volume production, manual assembly, or mixed component sourcing scenarios.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts are packaged in 0402 (1005 Metric) format with identical dimensions of 0.042" L x 0.022" W and maximum seated height of 0.033" (0.84mm). They are mechanically interchangeable on PCB layouts.

Q: Do both parts meet the same compliance standards?

A: Yes. Both FC0402E50R0FST1 and FC0402E50R0BST1 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, suitable for standard storage and handling conditions.

Q: Which part should I select for RF circuit applications?

A: Both parts are specified for RF and high-frequency applications with identical ±25ppm/°C temperature coefficient and -55°C to 155°C operating range. Selection depends on tolerance requirements: use FC0402E50R0FST1 for standard ±1% tolerance or FC0402E50R0BST1 for precision ±0.1% tolerance specifications.
