CJT2002R2JJ Equivalent & Substitute Parts

Part Overview

The CJT2002R2JJ is a 2.2 Ohms ±5% 200W wirewound chassis mount resistor manufactured by TE Connectivity Passive Product. This component is classified as obsolete, indicating it is no longer in active production. The CJT2002R2JJ belongs to the CJT and CGS series and features an aluminum housing with flanged mounting configuration and wire leads. Due to its obsolete status, identification of equivalent substitute parts is necessary for ongoing system maintenance, repair, and new design implementations where this resistance value and power rating are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CJT2002R2JJ is determined by the following critical parameters that must remain constant or be compatible with the original circuit design:

Core Electrical Parameters (Must Match):

• Resistance value: 2.2 Ohms
• Tolerance: ±5%
• Composition: Wirewound

Mechanical Parameters (Must Be Compatible):

• Mounting feature: Flanges
• Lead style: Wire Leads
• Housing type: Aluminum

Regulatory & Compliance Parameters:

• RoHS3 Compliance
• REACH Unaffected status

The CJH1250J2R2J qualifies as a substitute part because it maintains the same resistance value, tolerance, composition, mounting configuration, and regulatory compliance. The CJH1250J2R2J is an active product from TE Connectivity Passive Product, ensuring continued availability and support.

Parameter Comparison

Engineering Selection Recommendations

The CJH1250J2R2J is the qualified substitute for the obsolete CJT2002R2JJ based on the following engineering criteria:

Electrical Compatibility: Both parts maintain identical resistance values of 2.2 Ohms with ±5% tolerance and wirewound composition. The CJH1250J2R2J provides superior temperature coefficient performance at ±200ppm/°C compared to the original ±440ppm/°C, resulting in improved stability across operating temperature ranges.

Regulatory Compliance: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for component selection in new designs and legacy system replacements.

Product Availability: The CJH1250J2R2J is an active product with confirmed inventory availability, whereas the CJT2002R2JJ is obsolete. Selection of the active substitute ensures long-term supply chain continuity and support.

Power Rating Consideration: The CJH1250J2R2J provides 1250W power rating compared to the original 200W. This higher power capability is compatible with applications requiring the original 200W specification and provides additional thermal margin in power dissipation scenarios.

Physical Dimensions: The CJH1250J2R2J is larger in overall dimensions and height. Physical space availability in the target application must be confirmed prior to implementation.

Frequently Asked Questions (FAQ)

Q: Can the CJH1250J2R2J directly replace the CJT2002R2JJ in all applications?

A: The CJH1250J2R2J is electrically compatible as a substitute for the CJT2002R2JJ, maintaining the same resistance value, tolerance, and composition. Physical space constraints must be evaluated, as the substitute part has larger dimensions: 15.748" L x 2.638" W versus 6.496" L x 2.362" W for the original part.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete versus active), power rating (200W versus 1250W), temperature coefficient (±440ppm/°C versus ±200ppm/°C), and physical dimensions. The electrical resistance and tolerance specifications are identical.

Q: Are both parts RoHS compliant?

A: Yes, both the CJT2002R2JJ and CJH1250J2R2J are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: Why is the CJH1250J2R2J larger than the original part?

A: The increased physical size of the CJH1250J2R2J corresponds to its higher power rating of 1250W compared to the original 200W. Larger dimensions accommodate enhanced thermal dissipation capabilities.

Q: What is the operating temperature range for the substitute part?

A: The CJH1250J2R2J operates across the temperature range of -25°C to 250°C, providing extended thermal operating capability compared to the original part.

Q: Is the CJH1250J2R2J available in the same packaging as the CJT2002R2JJ?

A: The CJH1250J2R2J is supplied in box packaging. Both parts feature identical mounting configurations with flanged wire leads and aluminum housing construction.
