What risks should I check before replacing 0402WGF4642TCE?

Before replacing, check two main risks: 1) Resistance Mismatch: Ensure your circuit can tolerate resistance values that differ from the original 46.4kΩ. 2) Temperature Coefficient (TCR): The original part's TCR is unspecified; verify the candidate's TCR is suitable for your application's thermal stability requirements.

Find and compare replacements for the UNI-ROYAL 0402WGF4642TCE, a 46.4kΩ 1% 1/16W 0402 chip resistor. This guide provides pin-compatible and parametric alternatives to help you manage your bill of materials and supply chain.

AI replacement insight

Electrical risklow

For parametric alternatives, resistance differs up to 10%. The target's TCR is unknown, posing a minor risk.

Package risklow

All suggested candidates use the same 0402 package, ensuring form and fit compatibility.

Sourcing risklow

Candidates are from various manufacturers (FOJAN, Walsin, Yageo), providing supply chain flexibility.

Can it be replaced directly?

Direct replacement for 0402WGF4642TCE should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Start with Datasheet verified or Strong match candidates for 0402WGF4642TCE, then review parametric alternatives for package and electrical fit.

Main risk

The primary risk when substituting is a mismatch in resistance value. Several candidates have values from 43.2kΩ to 51kΩ, which may affect circuit performance.
