Substitute Part Grouping Explanation

Substitution of CW01033R00JS70 is based on electrical and mechanical parameter equivalence within the CW series wirewound resistor family. The substitute part CW01033R00JE73 maintains identical electrical specifications: 33 Ohm resistance, ±5% tolerance, 13W power rating, ±30ppm/°C temperature coefficient, and -65°C to 350°C operating range. Physical dimensions and axial package configuration remain unchanged. The primary difference is packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is supplied in Cut Tape (CT) configuration. Both parts are manufactured by Vishay Dale within the same CW series and share identical moisture-resistant wirewound construction.

Parameter Comparison

Engineering Selection Recommendations

CW01033R00JS70 and CW01033R00JE73 are electrically and mechanically equivalent components suitable for direct substitution in circuit applications. Selection between these parts should be based on the following criteria:

Use CW01033R00JS70 when Tape & Reel packaging is required for automated assembly processes or when RoHS non-compliant components are acceptable for the application.

Use CW01033R00JE73 when Cut Tape packaging is suitable for manual assembly or when ROHS3 compliance and REACH unaffected status are required by design specifications or regulatory requirements. This substitute also offers higher inventory availability at 1257 units compared to 794 units of the main part.

Both components maintain identical electrical performance and physical dimensions, ensuring functional interchangeability in circuit designs.

Frequently Asked Questions (FAQ)

Q: Are CW01033R00JS70 and CW01033R00JE73 electrically identical?

A: Yes. Both parts have identical resistance (33 Ohms), tolerance (±5%), power rating (13W), temperature coefficient (±30ppm/°C), and operating temperature range (-65°C to 350°C). They are electrically equivalent.

Q: What is the difference between these two parts?

A: The primary differences are packaging format and compliance status. CW01033R00JS70 is supplied in Tape & Reel format and is RoHS non-compliant with REACH Affected status. CW01033R00JE73 is supplied in Cut Tape format and is ROHS3 compliant with REACH Unaffected status.

Q: Can I use CW01033R00JE73 in place of CW01033R00JS70?

A: Yes, for circuit functionality. Both parts have identical electrical and mechanical specifications. However, verify that your assembly process accommodates Cut Tape packaging and that your application requirements align with the ROHS3 compliance and REACH unaffected status of the substitute.

Q: Does packaging format affect circuit performance?

A: No. Packaging format (Tape & Reel versus Cut Tape) affects only the delivery and handling method, not electrical performance or physical dimensions of the component itself.

Q: Which part should I select for new designs?

A: For new designs, CW01033R00JE73 is recommended due to ROHS3 compliance and REACH unaffected status, which align with current regulatory standards. Verify packaging compatibility with your assembly process.
