Key Parameters

Substitute Part Grouping Explanation

Substitution of the CP00052R700JE14 is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance value: 2.7 Ohms
• Tolerance: ±5%
• Power rating: 5W
• Composition: Wirewound
• Package configuration: Axial through-hole
• Safety and flame-proof features
• RoHS3 compliance

The substitute part TUW5J2R7E from Ohmite meets all these criteria. Both parts share identical resistance, tolerance, power rating, composition, and package type. Both are RoHS3 compliant and feature flame-proof, safety-rated construction. Mechanical dimensions differ slightly, but both maintain axial package geometry suitable for standard through-hole PCB mounting.

Parameter Comparison

Engineering Selection Recommendations

The TUW5J2R7E from Ohmite is the designated substitute for the obsolete CP00052R700JE14. Both parts satisfy identical electrical specifications: 2.7 Ohm resistance, ±5% tolerance, and 5W power rating in wirewound axial configuration. Both maintain RoHS3 compliance and flame-proof, safety-rated construction.

The TUW5J2R7E carries active product status, ensuring ongoing availability and supply chain support. The temperature coefficient difference (±400ppm/°C versus ±300ppm/°C) falls within acceptable engineering margins for most applications. Physical dimensions are equivalent within standard PCB layout tolerances for axial components.

Frequently Asked Questions (FAQ)

Q: Can the TUW5J2R7E directly replace the CP00052R700JE14 in existing designs?

A: Yes. Both parts meet identical electrical specifications: 2.7 Ohms, ±5% tolerance, 5W power rating, wirewound composition, and axial package configuration. Both are RoHS3 compliant with flame-proof, safety-rated features. Axial package dimensions are equivalent for standard through-hole PCB mounting.

Q: What is the significance of the temperature coefficient difference?

A: The CP00052R700JE14 specifies ±300ppm/°C while the TUW5J2R7E specifies ±400ppm/°C. This 100ppm/°C difference represents acceptable variation within wirewound resistor manufacturing tolerances and does not affect functional equivalence for standard applications.

Q: Why is the CP00052R700JE14 listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Vishay Dale. The TUW5J2R7E from Ohmite provides functional equivalence with active product status and current manufacturing support.

Q: Are there any mechanical compatibility concerns?

A: Both parts use axial through-hole package configuration. Dimensional variations (0.875" versus 0.866" length) are within standard PCB layout tolerances and do not affect mounting compatibility.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the CP00052R700JE14 and TUW5J2R7E are ROHS3 compliant and carry EAR99 ECCN classification with identical HTSUS codes (8533.21.0080).
