Procurement Notes

This component is officially listed as obsolete by Murata Electronics. Procurement should focus on verifying availability through authorized distributors or secondary market channels. Buyers must confirm the exact condition and authenticity of available stock, as standard supply chains no longer support this part number directly from the manufacturer.

Selection Notes

Engineers selecting this component should consider its obsolete status when designing new products. Alternative solutions with similar electrical characteristics and form factors should be evaluated to ensure long-term supply chain stability. Compatibility with existing circuit layouts and termination styles must be verified before substitution.

Part Context
