What risks should I check before replacing 1206W4F620LT5E?

Before replacing 1206W4F620LT5E, you must check two main risks. First, ensure the resistance value of the alternative is within your circuit's tolerance. Second, verify the Temperature Coefficient of Resistance (TCR) is the same or better (±100 ppm/°C), especially in temperature-sensitive or precision applications.

1206W4F620LT5E Alternatives, Datasheet & Cross Reference | UNI-ROYAL

Find and compare suitable replacements for the UNI-ROYAL 1206W4F620LT5E, a 0.62Ω 0.25W 1% 1206 chip resistor. This page analyzes pin-compatible options and parametric alternatives to help you make an informed sourcing decision.

AI replacement insight

Package risklow

All candidates use the standard 1206 package, ensuring form-fit compatibility.

Electrical riskmedium

Alternatives have different resistance values or unspecified/worse TCR, requiring engineering review.

Sourcing risklow

The target and candidates are common chip resistors from multiple vendors.

Can it be replaced directly?

Direct replacement for 1206W4F620LT5E should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

The strongest candidate is FRL1206FR620TS by FOJAN, which matches all key parameters except for a specified TCR. Verification of its datasheet is required. Parametric alternatives from UNI-ROYAL and FOJAN are also available if the application can tolerate small resistance changes.

Main risk

The primary risk when substituting is a mismatch in the Temperature Coefficient of Resistance (TCR), which is critical for precision circuits. The second risk is deviation from the 0.62Ω resistance value.

Recommended alternatives

A potential pin-to-pin replacement with matching resistance, power, and package; requires TCR verification.
