RSF3JB220R Equivalent & Substitute Parts

Part Overview

The RSF3JB220R is a 220 Ohms ±5% 3W through-hole resistor manufactured by Stackpole Electronics Inc. It features a metal oxide film composition with flame retardant coating and safety characteristics, designed for axial package applications. The part is currently active in production with 854 units in stock. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit component interchange based on electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RSF3JB220R are qualified based on the following critical parameters:

Electrical Compatibility Requirements:

• Resistance value: 220 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Composition: Metal Oxide Film (required for thermal and electrical characteristics)
• Package: Axial (required for PCB layout compatibility)

Mechanical Compatibility Requirements:

• Through-hole termination with 2 leads
• Axial lead configuration for standard PCB mounting

Regulatory & Compliance Requirements:

• RoHS3 Compliant status
• REACH Unaffected status
• ECCN: EAR99 classification

Two substitute parts meet these core criteria: ROX3SJ220R (TE Connectivity) and SQP500JB-220R (YAGEO). Both maintain the 220 Ohms ±5% resistance specification and axial package configuration. Variations in power rating, temperature coefficient, and operating temperature range are noted in the parameter comparison table below.

Engineering Selection Recommendations

ROX3SJ220R (TE Connectivity): This substitute maintains metal oxide film composition and 3W power rating identical to the RSF3JB220R. Operating temperature range extends to -55°C ~ 200°C, which covers the majority of industrial applications. Physical dimensions are slightly smaller (5.50mm x 16.00mm versus 6.00mm x 17.50mm), permitting direct PCB layout substitution in most designs. Temperature coefficient is ±350ppm/°C compared to ±200ppm/°C for the original part. All regulatory certifications (ROHS3, REACH, EAR99) are maintained. This part is recommended for applications where the original RSF3JB220R is unavailable and thermal stability requirements do not exceed ±350ppm/°C.

SQP500JB-220R (YAGEO): This substitute provides 5W power rating, exceeding the 3W specification of the RSF3JB220R. Composition is cement-based rather than metal oxide film. Operating temperature range is -55°C ~ 155°C, which is more restrictive than the original part. Physical dimensions are significantly larger (9.50mm x 9.00mm x 22.00mm), requiring PCB layout verification before substitution. All regulatory certifications (ROHS3, REACH, EAR99) are maintained. This part is suitable for applications requiring higher power dissipation capability or where space constraints permit the larger form factor.

Frequently Asked Questions (FAQ)

Q: Can ROX3SJ220R be used as a direct replacement for RSF3JB220R?

A: ROX3SJ220R qualifies as an electrical and mechanical substitute. Both parts share 220 Ohms ±5% resistance, 3W power rating, metal oxide film composition, and axial package configuration. Physical dimensions differ slightly (5.50mm x 16.00mm versus 6.00mm x 17.50mm), but this typically permits direct PCB substitution. Temperature coefficient variation (±350ppm/°C versus ±200ppm/°C) must be evaluated against circuit design tolerances.

Q: Is SQP500JB-220R suitable for applications designed for RSF3JB220R?

A: SQP500JB-220R meets the 220 Ohms ±5% electrical specification and axial package requirement. However, three factors require design review: (1) Composition is cement-based rather than metal oxide film, affecting thermal characteristics; (2) Operating temperature maximum is 155°C versus 235°C for the original part; (3) Physical dimensions are significantly larger (9.50mm x 9.00mm x 22.00mm), potentially requiring PCB layout modification. The 5W power rating provides margin above the 3W specification.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: resistance value (220 Ohms exact), tolerance (±5% exact), package type (axial), termination configuration (2-lead through-hole), and composition type (metal oxide film preferred for thermal stability). Operating temperature range, temperature coefficient, and physical dimensions must be verified against specific circuit requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. RSF3JB220R, ROX3SJ220R, and SQP500JB-220R are all ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the impact of different physical dimensions on PCB design?

A: ROX3SJ220R dimensions (5.50mm x 16.00mm) are slightly smaller than RSF3JB220R (6.00mm x 17.50mm), permitting direct substitution in existing PCB layouts. SQP500JB-220R dimensions (9.50mm x 9.00mm x 22.00mm) are significantly larger and rectangular rather than cylindrical, requiring PCB footprint verification and potential layout modification before substitution.
