Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters across all candidates:

• Resistance value: 56 Ohms
• Tolerance: ±5%
• Power rating: 3.75W
• Composition: Wirewound
• Package case: Axial
• Physical dimensions: 0.188" Dia x 0.562" L (4.78mm x 14.27mm)
• Temperature coefficient: ±30ppm/°C
• Operating temperature range: -65°C to 350°C
• Features: Moisture Resistant
• Terminations: 2

The substitute part CW02B56R00JE70 meets all electrical and mechanical requirements. The primary difference is packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is available in Cut Tape (CT) format. Both are manufactured by Vishay Dale within the same CW series.

Parameter Comparison

Engineering Selection Recommendations

Both CW02B56R00JS70 and CW02B56R00JE70 are functionally equivalent for circuit applications requiring a 56 Ohm, 3.75W axial wirewound resistor. Selection between these parts should be based on the following factors:

Packaging Requirements: Choose CW02B56R00JS70 if Tape & Reel packaging is required for automated assembly processes. Select CW02B56R00JE70 if Cut Tape format is acceptable or preferred for manual assembly or lower-volume applications.

Compliance Status: CW02B56R00JE70 offers ROHS3 compliance and REACH unaffected status, making it suitable for applications with regulatory compliance requirements. CW02B56R00JS70 is RoHS non-compliant and REACH affected, limiting its use in regulated markets.

Availability: CW02B56R00JE70 has higher inventory availability (1507 units) compared to CW02B56R00JS70 (865 units).

Frequently Asked Questions (FAQ)

Q: Can CW02B56R00JE70 be used as a direct replacement for CW02B56R00JS70?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Cut Tape versus Tape & Reel). Direct substitution is valid for circuit functionality.

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for high-speed automated assembly. Cut Tape (CT) packaging provides components on tape segments, suitable for manual assembly or lower-volume production runs.

Q: Are there compliance differences between these parts?

A: Yes. CW02B56R00JE70 is ROHS3 compliant and REACH unaffected, while CW02B56R00JS70 is RoHS non-compliant and REACH affected. Applications subject to environmental or regulatory restrictions should use CW02B56R00JE70.

Q: Do these parts have identical thermal and electrical performance?

A: Yes. Both parts share identical resistance (56 Ohms), tolerance (±5%), power rating (3.75W), temperature coefficient (±30ppm/°C), and operating temperature range (-65°C to 350°C).

Q: Which part should be selected for new designs?

A: CW02B56R00JE70 is recommended for new designs due to superior compliance status (ROHS3 compliant, REACH unaffected) and higher inventory availability.
