Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 40F560E is determined by strict equivalence across the following critical parameters:

• Resistance value: 560 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 10W (exact match required)
• Composition: Wirewound (exact match required)
• Package: Axial through-hole (exact match required)
• Temperature coefficient: ±20ppm/°C (exact match required)
• Termination count: 2 (exact match required)
• Regulatory compliance: ROHS3 Compliant (minimum requirement)

The Vishay Dale RS010560R0FE73 meets all substitution criteria as a direct equivalent part with identical electrical specifications and compatible mechanical dimensions.

Parameter Comparison

Engineering Selection Recommendations

Both the Ohmite 40F560E and Vishay Dale RS010560R0FE73 are Active status components with ROHS3 compliance and REACH Unaffected certification. The Vishay Dale RS010560R0FE73 provides an additional moisture-resistant feature and specified operating temperature range of -65°C to 250°C. Dimensional differences are minor, with the Vishay part measuring slightly smaller in both diameter and length while maintaining full electrical equivalence. Selection between these parts should be based on availability, packaging format requirements (Bulk versus Cut Tape), and environmental exposure considerations.

Frequently Asked Questions (FAQ)

Q: Can the Vishay Dale RS010560R0FE73 be used as a direct replacement for the Ohmite 40F560E?

A: Yes. Both parts share identical electrical specifications: 560 Ohms resistance, ±1% tolerance, 10W power rating, wirewound composition, and ±20ppm/°C temperature coefficient. Mechanical compatibility is confirmed through axial package equivalence. Dimensional variations are within acceptable tolerances for standard through-hole PCB applications.

Q: What is the significance of the moisture-resistant feature on the Vishay part?

A: The moisture-resistant designation on the RS010560R0FE73 indicates enhanced protection against moisture ingress. This feature is provided as additional specification data and does not affect substitution eligibility for applications where standard wirewound construction is acceptable.

Q: Are there packaging differences between these parts?

A: Yes. The Ohmite 40F560E is supplied in Bulk packaging, while the Vishay Dale RS010560R0FE73 is supplied in Cut Tape (CT) format. Packaging selection depends on assembly process requirements and inventory management practices.

Q: Do the dimensional differences affect PCB layout compatibility?

A: The Vishay part is slightly smaller (0.375" diameter versus 0.406", and 1.780" length versus 1.902"). These differences are minor and do not typically affect standard through-hole PCB designs. Verification with specific board layout requirements is the responsibility of the design engineer.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the Ohmite 40F560E and Vishay Dale RS010560R0FE73 are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component procurement.
