Key Parameters

Substitute Part Grouping Explanation

The CW01010R00JE73 qualifies as a parametric equivalent to the CW01010R00JS70 based on the following critical parameters:

• Identical resistance value: 10 Ohms
• Matching tolerance: ±5%
• Equivalent power rating: 13W
• Same composition: Wirewound
• Identical package type: Axial
• Matching temperature coefficient: ±30ppm/°C
• Same operating temperature range: -65°C to 350°C
• Identical physical dimensions: 0.375" Dia x 1.781" L (9.52mm x 45.24mm)
• Same feature set: Moisture Resistant

The primary difference between these parts is the packaging format: CW01010R00JS70 is supplied in Tape & Reel (TR) format, while CW01010R00JE73 is supplied in Cut Tape (CT) format. Both are manufactured by Vishay Dale within the CW series.

Parameter Comparison

Engineering Selection Recommendations

Both CW01010R00JS70 and CW01010R00JE73 are electrically and mechanically equivalent and suitable for direct substitution in circuit applications requiring a 10 Ohm, 13W wirewound axial resistor.

Selection between these parts should be based on:

• Packaging format requirements: Choose CW01010R00JS70 for Tape & Reel applications or CW01010R00JE73 for Cut Tape applications
• Compliance requirements: CW01010R00JE73 is ROHS3 Compliant, while CW01010R00JS70 is RoHS non-compliant
• Inventory availability: CW01010R00JE73 has significantly higher stock levels (3589 units versus 703 units)

Both parts carry identical electrical specifications and physical dimensions, ensuring functional interchangeability in the circuit design.

Frequently Asked Questions (FAQ)

Q: Can CW01010R00JE73 be used as a direct replacement for CW01010R00JS70?

A: Yes. Both parts are electrically and mechanically identical with matching resistance, tolerance, power rating, temperature coefficient, and operating temperature range. The primary difference is packaging format (Cut Tape versus Tape & Reel) and RoHS compliance status.

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

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on a reel, suitable for automated assembly equipment. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths, typically for manual assembly or smaller production runs.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both CW01010R00JS70 and CW01010R00JE73 share identical dimensions of 0.375" Dia x 1.781" L (9.52mm x 45.24mm), ensuring identical PCB footprint and mounting requirements.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental restrictions, not electrical performance. Both parts deliver identical electrical characteristics regardless of RoHS status.

Q: Which part should be selected for new designs?

A: CW01010R00JE73 is recommended for new designs due to ROHS3 compliance and higher inventory availability. However, either part is functionally suitable if specific packaging requirements or existing supply agreements dictate otherwise.
