Key Parameters

Substitute Part Grouping Explanation

The CW01033R00JE73 qualifies as a parametric equivalent to the CW01033R00JS67 based on identical electrical and mechanical specifications. Both parts share the same resistance value (33 Ohms), tolerance (±5%), power rating (13W), composition (wirewound), physical dimensions (0.375" Dia x 1.781" L), temperature coefficient (±30ppm/°C), and operating temperature range (-65°C ~ 350°C). The primary difference between these parts is packaging format: CW01033R00JS67 is supplied in Tape & Reel (TR) configuration, while CW01033R00JE73 is supplied in Cut Tape (CT) configuration. Both maintain the same axial package type and two-termination design.

Parameter Comparison

Engineering Selection Recommendations

Both CW01033R00JS67 and CW01033R00JE73 are functionally equivalent for circuit applications requiring a 33 Ohm, 13W axial wirewound resistor. Selection between these parts should be based on procurement and assembly requirements. The CW01033R00JS67 in Tape & Reel format is suitable for high-volume automated assembly operations. The CW01033R00JE73 in Cut Tape format accommodates lower-volume production runs or manual assembly processes. The CW01033R00JE73 offers ROHS3 compliance, whereas the CW01033R00JS67 is RoHS non-compliant. Compliance requirements should be evaluated against project specifications. Both parts maintain identical electrical performance and physical dimensions, ensuring direct interchangeability at the circuit level.

Frequently Asked Questions (FAQ)

Q: Can CW01033R00JE73 be used as a direct replacement for CW01033R00JS67?

A: Yes. Both parts are electrically and mechanically identical, with the same resistance value, tolerance, power rating, temperature coefficient, and operating temperature range. The difference is packaging format only.

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, optimized for automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on tape segments, suitable for manual assembly or lower-volume production.

Q: Does the packaging format affect electrical performance?

A: No. Packaging format does not affect electrical characteristics, performance, or reliability. The component itself remains identical.

Q: What is the significance of RoHS compliance differences?

A: CW01033R00JS67 is RoHS non-compliant, while CW01033R00JE73 is ROHS3 compliant. Projects with RoHS compliance requirements must use CW01033R00JE73. Projects without such requirements may use either part.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.375" Dia x 1.781" L (9.52mm x 45.24mm) and use the same axial package type, ensuring identical PCB footprint and mounting requirements.

Q: Which part should be selected for new designs?

A: Selection depends on assembly capability and compliance requirements. For automated assembly with RoHS compliance needs, use CW01033R00JE73. For manual assembly or non-compliant applications, either part is suitable based on packaging preference.
