Frequently Asked Questions (FAQ)

Q: Can the RL1220S-150-F be used as a direct replacement for the RP2012S-150-F in existing designs?

A: Yes. Both components share identical resistance value (15 Ohms), tolerance (±1%), power rating (0.333W), package format (0805), physical dimensions, operating temperature range (-55°C ~ 125°C), and temperature coefficient (0 / +200ppm/°C). The components are mechanically and electrically interchangeable within the specified parameters.

Q: What is the difference between metal film and thin film composition in these resistors?

A: The RP2012S-150-F uses metal film construction, while the RL1220S-150-F uses thin film construction. Both compositions deliver the specified ±1% tolerance and identical electrical performance across the operating temperature range. The thin film variant includes current sense functionality.

Q: Are both parts RoHS compliant?

A: Yes. Both the RP2012S-150-F and RL1220S-150-F are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Does the package format remain the same for both parts?

A: Yes. Both components use the 0805 (2012 Metric) surface mount package with identical physical dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum seated height of 0.020" (0.50mm). No PCB layout modifications are required.

Q: What is the moisture sensitivity level for these components?

A: Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.

Q: Why is the main part listed as obsolete?

A: The RP2012S-150-F carries obsolete product status. The RL1220S-150-F maintains active product status, providing continued availability and supply chain support for applications requiring 15 Ohm ±1% 0.333W 0805 resistors.
