Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ROX1SF470R is determined by the following critical parameters:

Primary Matching Criteria:

• Resistance value: 470 Ohms
• Power rating: 1W
• Package type: Axial through-hole
• Number of terminations: 2
• Operating temperature range compatibility: minimum -55°C ~ 130°C

Secondary Compatibility Factors:

• Tolerance: ±1% preferred; ±5% acceptable with design verification
• Composition: Metal oxide film or metal film
• Features: Flame proof and safety certifications required

The substitute parts identified maintain the core electrical specifications and physical form factor required for direct board-level replacement. Tolerance variations and composition differences represent acceptable trade-offs based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

ROX1SJ470R (TE Connectivity Passive Product)

This substitute maintains identical physical dimensions, composition, and operating temperature range to the ROX1SF470R. The primary difference is tolerance specification at ±5% versus ±1%. Both components are manufactured by TE Connectivity Passive Product within the ROX/Neohm series. The ROX1SJ470R holds active product status with ROHS3 compliance and REACH unaffected certification, ensuring long-term availability and regulatory alignment. This option is suitable for applications where ±5% tolerance meets circuit requirements.

FMF1WSFRF52-470R (YAGEO)

This substitute provides ±1% tolerance matching the original specification and extends the operating temperature range to -155°C. The composition differs as metal film rather than metal oxide film, with a superior temperature coefficient of ±100ppm/°C. Physical dimensions are slightly reduced (3.30mm x 9.00mm versus 3.50mm x 10.00mm), which may require board layout verification. The FMF1WSFRF52-470R is active product status with ROHS3 compliance and REACH unaffected certification. This option is suitable for applications requiring tighter tolerance and enhanced temperature stability.

Frequently Asked Questions (FAQ)

Q: Can ROX1SJ470R replace ROX1SF470R directly on the circuit board?

A: Yes. Both components share identical axial package dimensions (0.138" Dia x 0.394" L), resistance value (470 Ohms), power rating (1W), and operating temperature range (-55°C ~ 130°C). The tolerance difference (±5% versus ±1%) requires circuit-level evaluation to confirm acceptability.

Q: What is the primary difference between ROX1SJ470R and FMF1WSFRF52-470R?

A: ROX1SJ470R maintains metal oxide film composition with ±5% tolerance, while FMF1WSFRF52-470R uses metal film composition with ±1% tolerance and superior temperature coefficient (±100ppm/°C versus ±350ppm/°C). Physical dimensions differ slightly between the two options.

Q: Does FMF1WSFRF52-470R fit the same PCB footprint as ROX1SF470R?

A: FMF1WSFRF52-470R has reduced dimensions (3.30mm x 9.00mm versus 3.50mm x 10.00mm). While the axial package type remains compatible, board layout verification is required to confirm adequate spacing and clearance.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both ROX1SJ470R and FMF1WSFRF52-470R are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Q: Which substitute should be selected for precision-critical applications?

A: FMF1WSFRF52-470R is recommended for applications requiring ±1% tolerance and enhanced temperature stability. ROX1SJ470R is suitable for applications where ±5% tolerance is acceptable and composition consistency with the original part is prioritized.

Q: What is the availability status of these substitute parts?

A: ROX1SJ470R is active product status with 48,075 pieces in stock. FMF1WSFRF52-470R is active product status with 658 pieces in stock. Both components are available for immediate procurement.
