Substitute Part Grouping Explanation

The CW00568R00JE73 qualifies as a direct substitute for the CW00568R00JS73 based on identical electrical and mechanical parameters. Both parts share the same resistance value (68 Ohms), tolerance (±5%), power rating (6.5W), composition (wirewound), temperature coefficient (±30ppm/°C), operating temperature range (-65°C to 350°C), physical dimensions (0.312" Dia x 0.875" L), and moisture-resistant features. The primary difference is packaging format: CW00568R00JS73 is supplied in Tape & Reel (TR) configuration, while CW00568R00JE73 is supplied in Cut Tape (CT) configuration. Both parts maintain the same Axial package type and termination count (2 terminations).

Parameter Comparison

Engineering Selection Recommendations

The CW00568R00JE73 serves as a functional equivalent to the CW00568R00JS73 for applications requiring identical electrical performance. Selection between these parts should be based on packaging requirements and regulatory compliance needs. The CW00568R00JS73 in Tape & Reel format is suitable for automated assembly processes. The CW00568R00JE73 in Cut Tape format provides greater inventory availability (3112 units versus 924 units) and meets RoHS3 compliance requirements, making it the preferred choice for applications subject to RoHS3 regulations or when higher stock levels are advantageous for supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can CW00568R00JE73 be used as a direct replacement for CW00568R00JS73?

A: Yes. Both parts are electrically and mechanically identical, with the same 68 Ohm resistance, ±5% tolerance, 6.5W power rating, wirewound composition, and operating temperature range of -65°C to 350°C. The only difference is packaging format (Cut Tape versus Tape & Reel).

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

A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging provides individual component strips cut from the reel, typically used for manual assembly or lower-volume applications.

Q: Does the packaging format affect the component's electrical performance?

A: No. The electrical and thermal characteristics remain identical regardless of packaging format. The component itself is unchanged; only the delivery and handling format differs.

Q: Why would I choose CW00568R00JE73 over CW00568R00JS73?

A: Choose CW00568R00JE73 if RoHS3 compliance is required, if Cut Tape packaging suits your assembly process, or if higher inventory availability is needed for supply chain assurance.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both parts operate across the full temperature range of -65°C to 350°C with a temperature coefficient of ±30ppm/°C, making them suitable for demanding thermal environments.

Q: What does the moisture-resistant feature provide?

A: The moisture-resistant characteristic protects the wirewound resistor from environmental moisture ingress, extending reliability in humid or corrosive operating conditions.
