Substitute Part Grouping Explanation

Substitution between CW01025K00JS73 and CW01025K00JE73 is valid based on identical electrical and mechanical specifications. Both parts share the same resistance value, tolerance, power rating, composition, physical dimensions, temperature coefficient, and operating temperature range. The distinction between these parts is limited to packaging format: CW01025K00JS73 is supplied in Tape & Reel (TR) format, while CW01025K00JE73 is supplied in Cut Tape (CT) format. This packaging difference does not affect component performance or board-level compatibility. Substitution is appropriate when procurement requirements or inventory availability necessitate alternative packaging configurations.

Parameter Comparison

Engineering Selection Recommendations

Both CW01025K00JS73 and CW01025K00JE73 are active production parts suitable for equivalent substitution. Selection between these parts should be based on packaging requirements and regulatory compliance needs. CW01025K00JE73 offers ROHS3 compliance and REACH unaffected status, making it preferable for applications subject to environmental regulations. CW01025K00JS73 in Tape & Reel format is suitable for high-volume automated assembly operations. Both parts maintain identical electrical performance and physical compatibility with standard axial resistor footprints.

Frequently Asked Questions (FAQ)

Q: Can CW01025K00JE73 replace CW01025K00JS73 in existing designs? A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Cut Tape versus Tape & Reel). Board-level performance and footprint compatibility are unchanged.

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

Q: Are there compliance differences between these parts? A: Yes. CW01025K00JE73 is ROHS3 compliant and REACH unaffected, while CW01025K00JS73 is RoHS non-compliant and REACH affected. Applications requiring environmental compliance should specify CW01025K00JE73.

Q: Do these parts have identical physical dimensions? A: Yes. Both parts measure 0.375" diameter by 1.781" length (9.52mm x 45.24mm) and are compatible with standard axial resistor PCB layouts.

Q: What is the temperature coefficient specification? A: Both parts have a temperature coefficient of ±30ppm/°C across the operating range of -65°C to 350°C.
