Key Parameters

Substitute Part Grouping Explanation

Substitution of the ROX1SF560R is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 560 Ohms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 1W (exact match)
• Package configuration: Axial through-hole (exact match)

Mechanical Compatibility:

• Axial lead configuration for PCB mounting
• Physical dimensions compatible with standard 0.1" pitch through-hole spacing

Safety and Compliance:

• Flame-proof construction
• Safety-rated composition

The substitute part FMF1WSFRF52-560R meets all electrical and mechanical equivalence criteria. While the substitute employs metal film composition instead of metal oxide film, both compositions satisfy the specified electrical parameters and safety requirements for this application category.

Engineering Selection Recommendations

The FMF1WSFRF52-560R from YAGEO is a direct electrical equivalent to the obsolete ROX1SF560R. Selection of this substitute is supported by the following factors:

Product Status: The substitute part maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete original component.

Electrical Compatibility: Both parts deliver identical resistance (560 Ohms), tolerance (±1%), and power rating (1W). The substitute's improved temperature coefficient (±100ppm/°C versus ±350ppm/°C) provides enhanced stability across the operating temperature range.

Compliance and Certifications: The substitute part carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

Mechanical Fit: Both components utilize axial through-hole packaging with compatible lead configurations. Physical dimensions are within acceptable tolerance for standard PCB mounting applications, with the substitute featuring slightly reduced overall length (9.00mm versus 10.00mm).

Safety Features: Both parts maintain flame-proof and safety-rated construction appropriate for safety-critical circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the FMF1WSFRF52-560R directly replace the ROX1SF560R without circuit modification?

A: Yes. Both components are electrically equivalent with identical resistance, tolerance, and power rating specifications. The axial through-hole package configuration ensures mechanical compatibility with existing PCB designs. No circuit modifications are required.

Q: What is the difference between metal oxide film and metal film composition?

A: Both compositions meet the specified electrical parameters for this application. Metal film composition, used in the substitute part, typically offers improved temperature coefficient stability (±100ppm/°C versus ±350ppm/°C). Both compositions satisfy flame-proof and safety requirements.

Q: Are there dimensional compatibility concerns?

A: The substitute part is slightly smaller (3.30mm diameter, 9.00mm length) compared to the original (3.50mm diameter, 10.00mm length). Both components fit standard 0.1" pitch through-hole spacing and are compatible with conventional PCB mounting equipment and sockets.

Q: Does the substitute part meet current regulatory requirements?

A: Yes. The FMF1WSFRF52-560R carries ROHS3 compliance and REACH unaffected status, meeting current environmental and safety regulations for electronic component procurement and use.

Q: What is the operating temperature range difference?

A: The substitute part operates across -55°C to 155°C, compared to the original -55°C to 130°C. This extended upper temperature limit provides additional thermal margin in applications approaching the original component's maximum operating temperature.

Q: Is the substitute part available in the same packaging format?

A: The original part is supplied in standard packaging, while the substitute is available in Tape & Reel (TR) format. Both formats are compatible with standard component handling and assembly processes.
