UNI-ROYAL
Functional alternative with higher power (0.1W) but in a larger 0603 package.
Yageo's RC0402FR-07150RL is a standard 150Ω, 1%, 1/16W resistor in an 0402 package. While no direct drop-in replacements with an increased power safety margin are available, several functional and parametric alternatives exist that require engineering review.
High risk for non-0402 parts, which require a PCB redesign.
Medium risk for same-size parts due to lack of power safety margin.
No direct replacement meets the conservative 1.5x power rule. Pin-compatible parts exist but offer no additional power margin, requiring engineering review.
For new designs, upgrade to a larger package (0603/0805) for improved power handling. For existing layouts, use a pin-compatible part after verifying power derating.
Thermal stress. Using a part with the same power rating without verifying the application's actual power dissipation could lead to premature failure.

For new designs, consider an 0603 or 0805 package part like Yageo RC0805FR-07150RL for a higher power rating. For existing boards, FOJAN FRC0402F1500TS is a form-fit match but requires careful review of the circuit's power dissipation.
