Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RS02B20R00FS70 is determined by strict equivalence across the following critical parameters:

• Resistance value: 20 Ohms
• Tolerance: ±1%
• Power rating: 3W
• Composition: Wirewound
• Package type: Axial
• Temperature coefficient: ±20ppm/°C
• Operating temperature range: -65°C to 250°C
• Physical dimensions: 0.187" Dia x 0.560" L (4.75mm x 14.22mm)
• Termination count: 2
• Moisture resistance feature

The RS02B20R00FE70 meets all these criteria and is classified as a parametric equivalent. Packaging format differs (Cut Tape versus Tape & Reel), which does not affect electrical or mechanical compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RS02B20R00FS70 and RS02B20R00FE70 are electrically and mechanically equivalent for circuit applications. Selection between these parts should be based on the following factors:

The RS02B20R00FE70 offers improved regulatory compliance, meeting ROHS3 standards and REACH unaffected status, making it suitable for applications with stricter environmental and regulatory requirements. The RS02B20R00FS70 remains a valid selection for applications where RoHS non-compliance is acceptable and REACH-affected status does not present a constraint.

Packaging format selection (Tape & Reel versus Cut Tape) depends on assembly process requirements and volume considerations. Both formats maintain identical electrical and mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can RS02B20R00FE70 be used as a direct replacement for RS02B20R00FS70 in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent. All critical parameters including resistance, tolerance, power rating, temperature coefficient, operating temperature range, and physical dimensions are identical. The substitute part will function identically in circuit applications.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging is supplied on continuous tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) packaging is supplied as individual tape segments, suitable for lower-volume applications or manual assembly. Both formats contain the same component with identical electrical and mechanical specifications.

Q: Are there compliance differences between these parts?

A: Yes. The RS02B20R00FE70 is ROHS3 compliant and REACH unaffected, while the RS02B20R00FS70 is RoHS non-compliant and REACH affected. Applications subject to RoHS or REACH regulations should specify the RS02B20R00FE70.

Q: Do these parts have identical temperature performance?

A: Yes. Both parts share the same temperature coefficient of ±20ppm/°C and identical operating temperature range of -65°C to 250°C, ensuring equivalent thermal stability and performance across the full operating envelope.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical axial package dimensions of 0.187" diameter by 0.560" length (4.75mm x 14.22mm), ensuring mechanical compatibility with existing PCB layouts and component spacing.
