Substitute Part Grouping Explanation

Substitution eligibility for the CW01033R00JS73 is determined by strict equivalence across the following critical parameters:

  • Resistance value: 33 Ohms
  • Tolerance: ±5%
  • Power rating: 13W
  • Composition: Wirewound
  • Package type: Axial
  • Temperature coefficient: ±30ppm/°C
  • Operating temperature range: -65°C to 350°C
  • Physical dimensions: 0.375" Dia x 1.781" L
  • Moisture resistance feature
  • Number of terminations: 2

The CW01033R00JE73 meets all electrical and mechanical specifications required for direct substitution. The primary difference between these parts is packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is available in Cut Tape (CT) format.

Engineering Selection Recommendations

Both CW01033R00JS73 and CW01033R00JE73 are electrically and mechanically equivalent and suitable for direct substitution in circuit applications requiring a 33 Ohm, 13W axial wirewound resistor.

The CW01033R00JE73 offers compliance advantages: it is ROHS3 compliant and REACH unaffected, compared to the main part which is RoHS non-compliant and REACH affected. Selection between these parts should be based on:

  • Regulatory compliance requirements for the end application
  • Packaging format compatibility with assembly processes (Tape & Reel versus Cut Tape)
  • Inventory availability and procurement lead times
  • Supply chain and cost considerations

Both parts maintain identical electrical performance, temperature characteristics, and physical dimensions.

Frequently Asked Questions (FAQ)

Q: Can CW01033R00JE73 be used as a direct replacement for CW01033R00JS73?

A: Yes. Both parts are electrically and mechanically equivalent, with identical resistance, tolerance, power rating, temperature coefficient, operating temperature range, and physical dimensions. The primary difference is packaging format and compliance certifications.

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 components on tape segments, typically used for manual assembly or lower-volume production runs. Both formats contain the same component.

Q: Are there compliance differences between these parts?

A: Yes. The CW01033R00JE73 is ROHS3 compliant and REACH unaffected, while the CW01033R00JS73 is RoHS non-compliant and REACH affected. Applications subject to RoHS or REACH regulations should specify the CW01033R00JE73.

Q: Do these parts have identical thermal performance?

A: Yes. Both parts share the same temperature coefficient of ±30ppm/°C and operating temperature range of -65°C to 350°C.

Q: What determines substitution eligibility for this resistor?

A: Substitution is based on matching resistance value, tolerance, power rating, composition, package type, temperature coefficient, operating temperature range, physical dimensions, and feature set. All these parameters must be identical for direct substitution.
