Key Parameters

Substitute Part Grouping Explanation

The CW01025R00JE73 qualifies as a parametric equivalent to the CW01025R00JS733 based on the following critical parameters:

• Resistance value: 25 Ohms (identical)
• Tolerance: ±5% (identical)
• Power rating: 13W (identical)
• Composition: Wirewound (identical)
• Package case: 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 (identical)
• Moisture resistance: Present (identical)

The primary difference between these parts is packaging format: the main part uses tape and reel (TR) packaging, while the substitute uses cut tape (CT) packaging. Additionally, the substitute part carries RoHS3 compliance certification, whereas the main part is RoHS non-compliant.

Engineering Selection Recommendations

The CW01025R00JE73 serves as a direct functional substitute for the CW01025R00JS733 in applications where electrical and thermal performance specifications are identical. Selection between these parts should be based on the following criteria:

Choose CW01025R00JS733 when:

• Tape and reel packaging is required for automated assembly processes
• RoHS non-compliant designs are acceptable for the application

Choose CW01025R00JE73 when:

• Cut tape packaging is compatible with assembly operations
• RoHS3 compliance is mandated by design requirements or regulatory standards
• REACH compliance is required
• Higher inventory availability is beneficial for supply chain planning

Both parts maintain identical electrical characteristics, thermal performance, and physical dimensions, ensuring functional interchangeability at the component level.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically identical? A: Yes. Both parts share identical resistance (25 Ohms), tolerance (±5%), power rating (13W), temperature coefficient (±30ppm/°C), and operating temperature range (-65°C to 350°C).

Q: What is the difference between tape and reel and cut tape packaging? A: Tape and reel (TR) packaging supplies components on a continuous reel suitable for high-speed automated pick-and-place assembly. Cut tape (CT) packaging provides components on tape segments, typically used for lower-volume assembly or manual placement. Both formats contain identical components.

Q: Can I use CW01025R00JE73 as a direct replacement for CW01025R00JS733? A: Yes, provided your assembly process can accommodate cut tape packaging instead of tape and reel. The electrical and mechanical specifications are identical.

Q: Why does the substitute part have RoHS3 compliance while the main part does not? A: RoHS compliance status reflects manufacturing process and material composition choices made by the manufacturer. The CW01025R00JE73 was manufactured to meet RoHS3 standards, while the CW01025R00JS733 was not. Both parts function identically in circuit applications.

Q: Which part should I specify for new designs? A: For new designs requiring RoHS3 compliance, specify CW01025R00JE73. For legacy designs or applications without RoHS requirements, either part is acceptable based on packaging availability and supply chain considerations.

Q: Are the physical dimensions identical? A: Yes. Both parts measure 0.375" diameter by 1.781" length (9.52mm x 45.24mm), ensuring identical PCB footprint and mounting characteristics.
