CW01018K00JS73 Equivalent & Substitute Parts

Part Overview

The CW01018K00JS73 is an 18 kOhms ±5% 13W through-hole resistor manufactured by Vishay Dale in the CW series. This axial wirewound resistor features moisture-resistant construction and operates across a wide temperature range from -65°C to 350°C. The part is currently active in production. Substitute parts are identified when packaging format changes or when compliance requirements necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution between CW01018K00JS73 and CW01018K00JE73 is based on electrical and mechanical parameter equivalence. Both parts share identical resistance value, tolerance, power rating, composition, package type, physical dimensions, temperature coefficient, and operating temperature range. The primary difference is packaging format: CW01018K00JS73 is supplied in Tape & Reel (TR) format, while CW01018K00JE73 is supplied in Cut Tape (CT) format. Both maintain the same axial configuration and termination count. Substitution is valid when packaging format compatibility with assembly equipment and inventory management requirements permits the change.

Parameter Comparison

Engineering Selection Recommendations

Selection between CW01018K00JS73 and CW01018K00JE73 depends on regulatory compliance requirements and packaging format compatibility. CW01018K00JE73 offers ROHS3 compliance and REACH unaffected status, making it suitable for applications with strict environmental regulations. CW01018K00JS73 maintains RoHS non-compliant status but is available in Tape & Reel format for high-volume automated assembly. Both parts are active products from Vishay Dale with identical electrical performance and physical dimensions. Selection should be based on compliance mandates and assembly equipment specifications.

Frequently Asked Questions (FAQ)

Q: Can CW01018K00JE73 replace CW01018K00JS73 in my circuit? A: Yes, electrically and mechanically. Both parts have identical resistance, tolerance, power rating, temperature coefficient, and operating temperature range. Verification of packaging format compatibility with your assembly equipment is required.

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Tape & Reel (TR) format supplies components on continuous tape wound on reels, suitable for automated pick-and-place assembly. Cut Tape (CT) format supplies components on tape segments, typically for lower-volume or manual assembly operations. Both formats contain the same component.

Q: Does the substitute part have different compliance certifications? A: Yes. CW01018K00JE73 is ROHS3 compliant and REACH unaffected, while CW01018K00JS73 is RoHS non-compliant and REACH affected. Applications requiring environmental compliance should use CW01018K00JE73.

Q: Are the physical dimensions identical? A: Yes. Both parts measure 0.375" diameter by 1.781" length (9.52mm x 45.24mm) in axial configuration with two terminations.

Q: Can I use these parts interchangeably in high-temperature applications? A: Yes. Both parts operate across the identical temperature range of -65°C to 350°C with the same ±30ppm/°C temperature coefficient.
