Is there a pin-compatible replacement for RS-06K39R0FT?

Yes, parts like Yageo RC1206FR-0736RL share the same 1206 package, power rating, and tolerance, making them physically similar. However, they have a 36Ω resistance instead of 39Ω, which requires design validation before being considered a drop-in replacement.

What risks should I check before replacing RS-06K39R0FT?

The main risk is the resistance difference; most available alternatives are 36Ω, not 39Ω. Also, ensure the replacement has the same or better tolerance (±1%), power rating (0.25W), and temperature coefficient (±100ppm/°C).

RS-06K39R0FT Alternatives, Datasheet & Cross Reference | Guangdong Fenghua Advanced Technology Holding Co., Ltd.

RS-06K39R0FT is a general-purpose 39Ω 1% 0.25W thick film resistor in a 1206 package. Common alternatives typically involve adjacent standard resistance values like 36Ω, which requires engineering review to ensure circuit compatibility.

AI replacement insight

Electrical riskmedium

Resistance value differs by -7.7%, requiring circuit analysis.

Package risklow

All viable candidates share the same 1206 package.

Sourcing risklow

36Ω is a standard, widely available resistor value.

Can it be replaced directly?

No exact 39Ω direct replacement was found in this batch. The closest options are 36Ω resistors, which are parametrically similar but require engineering review for the resistance change.

Best replacement path

Use a 36Ω, 1% tolerance, 0.25W resistor in a 1206 package from a reputable manufacturer like Yageo or UNI-ROYAL, after verifying the resistance change is acceptable.

Main risk

The primary risk is the change in resistance from 39Ω to 36Ω (-7.7%), which could affect circuit timing, biasing, or feedback loops.

Recommended alternatives

Close parametric match with identical package, power, and tolerance, but with 36Ω resistance.
