Key Parameters

Substitute Part Grouping Explanation

The CW010330R0JE73 qualifies as a direct substitute for the CW010330R0JS73 based on the following critical parameters:

• Identical resistance value: 330 Ohms
• Identical tolerance: ±5%
• Identical power rating: 13W
• Identical composition: Wirewound
• Identical package type: Axial
• Identical temperature coefficient: ±30ppm/°C
• Identical operating temperature range: -65°C to 350°C
• Identical physical dimensions: 0.375" Dia x 1.781" L (9.52mm x 45.24mm)
• Identical number of terminations: 2

The primary difference between these parts is the packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is supplied in Cut Tape (CT) format.

Parameter Comparison

Engineering Selection Recommendations

Both the CW010330R0JS73 and CW010330R0JE73 are functionally equivalent for circuit applications requiring a 330 Ohm, 13W wirewound resistor with ±5% tolerance and moisture-resistant construction.

The CW010330R0JE73 offers improved compliance status: it is ROHS3 compliant and REACH unaffected, whereas the main part is RoHS non-compliant and REACH affected. Selection between these parts should be based on:

1. Packaging requirements: Tape & Reel (TR) format for automated assembly processes versus Cut Tape (CT) format for manual or lower-volume applications
2. Regulatory compliance mandates: Projects requiring ROHS3 compliance and REACH unaffected status should specify the CW010330R0JE73
3. Inventory availability: The CW010330R0JE73 maintains higher stock levels (4178 Pcs) compared to the CW010330R0JS73 (830 Pcs)

Frequently Asked Questions (FAQ)

Q: Can CW010330R0JE73 be used as a direct replacement for CW010330R0JS73 in existing designs?

A: Yes. All electrical and mechanical parameters are identical. The only difference is packaging format (Cut Tape versus Tape & Reel). Circuit performance and board-level compatibility remain unchanged.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for high-speed automated pick-and-place assembly. Cut Tape packaging supplies the same components on tape segments, typically used for manual assembly or lower-volume production runs.

Q: Does the packaging format affect the component's electrical performance?

A: No. The component itself is identical. Packaging format only affects handling, storage, and assembly methodology.

Q: Why does CW010330R0JE73 have better compliance status?

A: Compliance status reflects the manufacturing process and materials used. The CW010330R0JE73 meets ROHS3 requirements and is REACH unaffected, indicating it was manufactured under stricter environmental and substance restriction standards.

Q: Are there any thermal or environmental performance differences between these parts?

A: No. Both parts operate identically across the -65°C to 350°C temperature range with ±30ppm/°C temperature coefficient and identical moisture-resistant construction.

Q: Which part should be selected for new designs?

A: For new designs, the CW010330R0JE73 is the preferred selection due to superior compliance status and higher inventory availability, unless specific Tape & Reel packaging requirements mandate the CW010330R0JS73.
