Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CB25JB200R is determined by the following critical parameters:

• Resistance value: 200 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 25W (exact match required)
• Composition: Wirewound (exact match required)
• Package type: Axial (exact match required)
• Operating temperature range: -55°C to 275°C (minimum requirement)
• Features: Flame Proof, Moisture Resistant, Safety (required for equivalent functionality)
• RoHS compliance: ROHS3 Compliant (regulatory requirement)

The WCB25JB200R0 meets all substitution criteria as a direct equivalent part from the same manufacturer.

Frequently Asked Questions (FAQ)

Q: Can the WCB25JB200R0 be used as a direct replacement for the CB25JB200R?

A: Yes. Both parts share identical resistance (200 Ohms), tolerance (±5%), power rating (25W), composition (wirewound), package type (axial), operating temperature range (-55°C to 275°C), and safety features (flame proof, moisture resistant). Physical dimensions are identical at 2.500" L x 0.500" W.

Q: What is the difference between the CB25JB200R and WCB25JB200R0?

A: The primary differences are product status and temperature coefficient. The CB25JB200R is obsolete with a temperature coefficient of ±200ppm/°C, while the WCB25JB200R0 is active production with a superior temperature coefficient of ±20ppm/°C. The WCB series offers improved thermal stability.

Q: Are there any packaging differences between these parts?

A: The CB25JB200R uses standard packaging, while the WCB25JB200R0 is supplied in bulk packaging. Both maintain identical axial form factor and physical dimensions suitable for through-hole PCB assembly.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the CB25JB200R and WCB25JB200R0 are ROHS3 compliant and REACH unaffected, meeting current electronic component regulatory standards.

Q: Which part should be selected for new designs?

A: The WCB25JB200R0 is recommended for new designs due to its active production status, higher inventory availability, and improved temperature coefficient performance.
