Both parts share equivalent RoHS non-compliance and REACH Affected status, ensuring consistent regulatory treatment in procurement and supply chain management. Selection between these parts should be based on availability, failure rate requirements, and application-specific reliability objectives.

Frequently Asked Questions (FAQ)

Q: Can RLR05C3012FSB14 be used as a direct replacement for RLR05C3012FPBSL?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 30.1 kOhms ±1% resistance, 0.125W power rating, metal film composition, ±100ppm/°C temperature coefficient, -65°C to 150°C operating range, and identical axial package dimensions. Direct substitution is supported without circuit modification.

Q: What is the difference between failure rate classifications P and S?

A: Failure rate P (0.1%) and S (0.001%) represent different reliability grades within military specifications. RLR05C3012FSB14 with S classification indicates a lower predicted failure rate, suitable for applications requiring enhanced reliability margins.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts measure 0.066" diameter × 0.150" length (1.68mm × 3.81mm) in axial configuration, ensuring identical PCB footprint and mechanical fit.

Q: Do both parts meet the same military specifications?

A: Yes. Both RLR05C3012FPBSL and RLR05C3012FSB14 are classified under the military RLR05 series per MIL-PRF-39017/05 specification and share identical moisture resistance and weldability features.

Q: What is the impact of different inventory levels on substitution?

A: Inventory levels (732 units for RLR05C3012FPBSL versus 1131 units for RLR05C3012FSB14) reflect current stock availability and do not affect electrical or mechanical compatibility. Selection may be influenced by supply chain lead times and procurement requirements.
