Frequently Asked Questions (FAQ)

Q: Can RLR07C47R5FSB14 be used as a direct replacement for RLR07C47R5FSBSL?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (47.5 Ohms ±1%, 0.25W), identical temperature characteristics (±100ppm/°C, -65°C to 150°C operating range), and identical mechanical packaging (0.090" Dia x 0.250" L axial configuration). No circuit redesign or board layout modification is required.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts share identical compliance status: RoHS non-compliant, REACH Affected, ECCN EAR99, and HTSUS 8533.21.0090. Both are certified to MIL-PRF-39017/01 military specifications with identical failure rate ratings of S (0.001%).

Q: What is the difference between the part numbers?

A: The part numbers differ only in their suffix designations (FSBSL versus FSB14). This variation reflects different packaging or distribution batches from Vishay Dale but does not indicate any electrical or mechanical specification changes.

Q: Can these parts be used interchangeably in military or aerospace applications?

A: Yes. Both parts are military-grade components from the RLR07 series with identical MIL-PRF-39017/01 compliance, moisture-resistant construction, and weldable terminations. They are functionally equivalent for all military and aerospace circuit applications.

Q: What should be considered when selecting between these substitute parts?

A: Selection should be based on inventory availability and procurement lead times. The RLR07C47R5FSBSL has 1122 units in stock, while the RLR07C47R5FSB14 has 1396 units available. Both parts are active products with no planned obsolescence.
