Substitute Part Grouping Explanation

Substitution eligibility for the CW02C50R00JS70 is determined by strict equivalence in the following parameters:

• Resistance value: 50 Ohms
• Tolerance: ±5%
• Power rating: 3.25W
• Composition: Wirewound
• Package case: Axial
• Physical dimensions: 0.218" Dia x 0.500" L (5.54mm x 12.70mm)
• Temperature coefficient: ±30ppm/°C
• Operating temperature range: -65°C to 350°C
• Features: Moisture Resistant

Packaging format (tape and reel versus cut tape) and RoHS compliance status are secondary considerations that do not affect electrical or mechanical compatibility. The CW02C50R00JE70 meets all primary substitution criteria while differing only in packaging delivery method and regulatory compliance classification.

Parameter Comparison

Engineering Selection Recommendations

Both the CW02C50R00JS70 and CW02C50R00JE70 are electrically and mechanically identical. Selection between these parts should be based on:

• Packaging requirement: Choose tape and reel format for automated assembly processes; select cut tape format for manual or lower-volume applications.
• Regulatory compliance: The CW02C50R00JE70 carries ROHS3 compliance certification, making it suitable for applications subject to RoHS3 regulatory requirements. The CW02C50R00JS70 is RoHS non-compliant and should be selected only when RoHS compliance is not mandated.
• Inventory availability: The CW02C50R00JE70 offers higher stock levels (1270 units) compared to the CW02C50R00JS70 (782 units).

Both parts maintain identical electrical performance, temperature stability, and moisture resistance characteristics across all operating conditions.

Frequently Asked Questions (FAQ)

Q: Can CW02C50R00JE70 be used as a direct replacement for CW02C50R00JS70?

A: Yes. Both parts are electrically and mechanically equivalent. The CW02C50R00JE70 differs only in packaging format (cut tape versus tape and reel) and RoHS compliance status. No circuit redesign or board layout modification is required.

Q: What is the difference between tape and reel and cut tape packaging?

A: Tape and reel packaging is supplied on continuous carrier tape wound on a reel, optimized for automated pick-and-place assembly equipment. Cut tape packaging provides the same components on shorter tape segments, suitable for manual assembly or lower-volume production runs. Both formats contain identical components.

Q: Does the RoHS3 compliance of CW02C50R00JE70 affect electrical performance?

A: No. RoHS3 compliance is a regulatory and material composition classification that does not alter electrical specifications, performance characteristics, or operating parameters. The CW02C50R00JE70 maintains identical resistance, power rating, temperature coefficient, and operating temperature range as the CW02C50R00JS70.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both the CW02C50R00JS70 and CW02C50R00JE70 share identical physical dimensions of 0.218" diameter by 0.500" length (5.54mm x 12.70mm). No PCB layout modifications are necessary when substituting between these parts.

Q: Which part should be selected for high-temperature applications?

A: Both parts are rated for identical operating temperatures from -65°C to 350°C. Selection should be based on packaging format and compliance requirements rather than thermal performance, as thermal specifications are equivalent.
