Substitute Part Grouping Explanation

Substitution eligibility for the CW0102R000JS73 is determined by equivalence across the following critical parameters:

• Resistance value: 2 Ohms
• Tolerance: ±5%
• Power rating: 13W
• Composition: Wirewound
• Package case: Axial
• Physical dimensions: 0.375" Dia x 1.781" L (9.52mm x 45.24mm)
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -65°C ~ 350°C
• Features: Moisture Resistant

The CW0102R000JE73 meets all these criteria. The only difference between the main part and its substitute is the packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is supplied in Cut Tape (CT) configuration. Both formats contain identical components suitable for the same electrical and mechanical applications.

Engineering Selection Recommendations

Both the CW0102R000JS73 and CW0102R000JE73 are electrically and mechanically equivalent and suitable for identical circuit applications. Selection between these parts should be based on the following factors:

The CW0102R000JE73 offers compliance advantages, meeting ROHS3 requirements and REACH unaffected status, making it preferable for applications subject to environmental regulations. The CW0102R000JS73 in Tape & Reel packaging is optimized for high-volume automated assembly processes, while the CW0102R000JE73 in Cut Tape format provides flexibility for lower-volume or manual assembly operations. Both parts maintain active production status and are available in substantial inventory quantities.

Frequently Asked Questions (FAQ)

Q: Can CW0102R000JE73 be used as a direct replacement for CW0102R000JS73?

A: Yes. Both parts are electrically and mechanically identical, with matching resistance values, power ratings, temperature coefficients, and physical dimensions. The only difference is packaging format: Tape & Reel versus Cut Tape.

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

Q: Are there compliance differences between these parts?

A: Yes. The CW0102R000JE73 is ROHS3 compliant and REACH unaffected, while the CW0102R000JS73 is RoHS non-compliant and REACH affected. Applications requiring environmental compliance should specify the CW0102R000JE73.

Q: Do these parts have the same operating temperature range?

A: Yes. Both parts operate from -65°C to 350°C with identical temperature coefficients of ±50ppm/°C.

Q: Which part should be selected for new designs?

A: Selection depends on assembly method and regulatory requirements. For automated assembly with environmental compliance requirements, specify CW0102R000JE73. For manual assembly or legacy designs without compliance constraints, either part is suitable based on packaging availability.
