Key Parameters

Substitute Part Grouping Explanation

Substitution for the CP0010R3300JB14 is based on the following critical parameters:

• Resistance value: 330 mOhms (exact match required)
• Tolerance: ±5% (electrical performance equivalence)
• Power rating: 10W (thermal capability match)
• Composition: Wirewound (construction type)
• Package: Axial (mechanical and electrical interface compatibility)
• Features: Flame Proof, Safety (safety and regulatory requirements)
• Termination count: 2 (pin configuration)

The TUW10JR33E from Ohmite meets all these critical parameters and is qualified as a manufacturer-recommended substitute.

Engineering Selection Recommendations

The TUW10JR33E is the qualified substitute for the obsolete CP0010R3300JB14. Selection should be based on the following factors:

Product Status: The CP0010R3300JB14 is obsolete, whereas the TUW10JR33E is active and in production, ensuring long-term availability and supply chain continuity.

Compliance: The TUW10JR33E is ROHS3 compliant, meeting current regulatory requirements for new designs. The original CP0010R3300JB14 is RoHS non-compliant and unsuitable for applications requiring environmental compliance.

Electrical Performance: Both parts are electrically equivalent with identical resistance, tolerance, and power ratings. The TUW10JR33E exhibits a lower temperature coefficient (±400ppm/°C versus ±600ppm/°C), providing improved temperature stability in applications with wide operating temperature ranges.

Mechanical Compatibility: Both parts use axial packaging with identical termination configuration, ensuring direct mechanical and electrical interface compatibility in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the TUW10JR33E be used as a direct replacement for the CP0010R3300JB14?

A: Yes. Both parts share identical electrical specifications (330 mOhms, ±5%, 10W), composition (wirewound), safety features (flame proof, safety-rated), and axial package configuration. The TUW10JR33E is the manufacturer-recommended substitute.

Q: What is the difference in temperature coefficient between these parts?

A: The CP0010R3300JB14 has a temperature coefficient of ±600ppm/°C, while the TUW10JR33E has ±400ppm/°C. The lower coefficient in the substitute part indicates better resistance stability across temperature variations, which is advantageous in precision applications.

Q: Are there packaging differences between these parts?

A: Both parts use axial packaging. Physical dimensions differ slightly: the CP0010R3300JB14 measures 1.875" L x 0.375" W (47.62mm x 9.52mm), while the TUW10JR33E measures 1.929" L x 10.00mm x 9.00mm. These dimensional variations are typical between manufacturers and do not affect electrical performance or standard PCB layout compatibility.

Q: Is the TUW10JR33E suitable for new designs?

A: Yes. The TUW10JR33E is active in production and ROHS3 compliant, making it the appropriate choice for new designs requiring current regulatory compliance and long-term component availability.

Q: What is the inventory status of these parts?

A: The CP0010R3300JB14 has 754 pieces in stock but is obsolete. The TUW10JR33E has 1552 pieces in stock and is active, providing superior supply chain reliability for ongoing production.
