Parameter Comparison

Engineering Selection Recommendations

The 805F2R0E is the appropriate selection for applications currently using or specifying the obsolete 805F2R0. Both components maintain identical electrical performance and mechanical compatibility, ensuring direct substitution without circuit redesign.

The 805F2R0E offers the additional advantage of Active product status, ensuring long-term availability and supply chain continuity. The component also meets ROHS3 compliance requirements, addressing regulatory requirements for new designs and manufacturing environments subject to RoHS directives.

Both components remain REACH Unaffected and carry EAR99 export classification. Selection between these parts should be based on product lifecycle requirements and regulatory compliance mandates applicable to the end application.

Frequently Asked Questions (FAQ)

Q: Can the 805F2R0E directly replace the 805F2R0 in existing designs?

A: Yes. The 805F2R0E maintains identical electrical specifications (2 Ohms ±1%, 5W), thermal characteristics (±50ppm/°C, -55°C to 275°C operating range), and mechanical dimensions (0.600" L x 0.646" W, 0.330" height). Flanged mounting and solder lug termination are identical, enabling direct substitution without PCB or assembly modifications.

Q: What is the primary difference between these two part numbers?

A: The 805F2R0 is classified as Obsolete, while the 805F2R0E is Active. The 805F2R0E is supplied in Tray packaging and meets ROHS3 compliance, whereas the 805F2R0 is RoHS non-compliant. Electrical and mechanical performance are equivalent.

Q: Are there packaging considerations when switching from 805F2R0 to 805F2R0E?

A: The 805F2R0E is supplied in Tray packaging format, whereas the 805F2R0 uses standard packaging. This affects bulk ordering and inventory management but does not impact component performance or installation procedures.

Q: Does the 805F2R0E meet current regulatory requirements?

A: The 805F2R0E is ROHS3 Compliant and REACH Unaffected. The 805F2R0 is RoHS non-compliant. For applications subject to RoHS directives or regulatory compliance mandates, the 805F2R0E is the appropriate selection.

Q: What inventory status should be considered when selecting between these parts?

A: The 805F2R0 (Obsolete) has 876 pieces in stock. The 805F2R0E (Active) has 909 pieces in stock. For long-term supply assurance, the Active status of the 805F2R0E provides superior availability and lifecycle support.
