ROX2SJ2R7 Equivalent & Substitute Parts

Part Overview

The ROX2SJ2R7 is a 2.7 Ohm, 2W axial through-hole resistor manufactured by TE Connectivity Passive Product. This metal oxide film resistor is designed for applications requiring flame-proof and pulse-withstanding characteristics with safety ratings. The component is classified as Active product status with full RoHS3 compliance and REACH unaffected designation.

Substitute parts are identified when equivalent electrical specifications, mechanical compatibility, and regulatory compliance can be maintained across alternative manufacturers. This ensures design flexibility and supply chain continuity without compromising circuit performance or safety requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ROX2SJ2R7 is determined by strict alignment of the following parameters:

Electrical Specifications:

• Resistance value: 2.7 Ohms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film

Mechanical Specifications:

• Package configuration: Axial through-hole
• Number of terminations: 2
• Physical form factor: Axial lead resistor

Regulatory & Compliance:

• RoHS3 compliance required
• REACH unaffected status
• Flame-proof and safety-rated construction

Substitute parts must satisfy all electrical and mechanical parameters while maintaining or exceeding the operating temperature range and regulatory compliance status of the primary component.

Parameter Comparison

Engineering Selection Recommendations

ROX2SJ2R7 (Primary Component): The TE Connectivity ROX2SJ2R7 is the specified component with active product status, full RoHS3 compliance, and documented pulse-withstanding capability. This component is suitable for applications requiring the complete feature set including pulse withstanding characteristics.

RSF200JB-73-2R7 (Substitute Component): The YAGEO RSF200JB-73-2R7 provides electrical and mechanical equivalence with identical resistance, tolerance, power rating, and composition. Both components maintain RoHS3 compliance and REACH unaffected status. The substitute component operates across an extended temperature range (-55°C to 235°C versus -55°C to 200°C), providing additional thermal margin. Physical length differs by 3.50mm (15.50mm versus 12.00mm), which must be evaluated for board layout compatibility. The substitute component does not document pulse-withstanding capability; applications requiring this specific feature must retain the primary component.

Frequently Asked Questions (FAQ)

Q: Can RSF200JB-73-2R7 be used as a direct replacement for ROX2SJ2R7?

A: Electrical and mechanical substitution is valid for applications not requiring pulse-withstanding characteristics. The substitute component matches resistance, tolerance, power rating, composition, and package type. Physical length difference (3.50mm) must be accommodated in board layout. Both components maintain identical RoHS3 and REACH compliance status.

Q: What is the impact of the physical dimension difference?

A: The RSF200JB-73-2R7 is 3.50mm longer (15.50mm total length versus 12.00mm). This difference affects board layout spacing and lead bend radius. Verify clearance in the target application before substitution.

Q: Are both components suitable for high-temperature applications?

A: The RSF200JB-73-2R7 operates to 235°C, exceeding the ROX2SJ2R7 maximum of 200°C. For applications approaching or exceeding 200°C, the substitute component provides additional thermal margin. Temperature coefficient specifications differ; the ROX2SJ2R7 specifies ±350ppm/°C while the substitute does not document this parameter.

Q: Does the substitute component meet pulse-withstanding requirements?

A: The RSF200JB-73-2R7 does not document pulse-withstanding capability. Applications requiring this feature must use the primary ROX2SJ2R7 component.

Q: Are packaging formats compatible?

A: The ROX2SJ2R7 is supplied in Cut Tape (CT) packaging, while RSF200JB-73-2R7 is supplied in Bulk packaging. Both components are axial through-hole resistors with identical lead configurations and termination count (2). Packaging format does not affect electrical or mechanical compatibility.

Q: What regulatory compliance applies to both components?

A: Both components are RoHS3 compliant and REACH unaffected. No regulatory barriers exist for substitution in applications subject to these standards.
