MOSX2CT52R2R7J Equivalent & Substitute Parts

Part Overview

The MOSX2CT52R2R7J is a 2.7 Ohm, 2W axial through-hole resistor manufactured by KOA Speer Electronics, Inc. This metal oxide film resistor features flame retardant coating and safety design characteristics, operating across a temperature range of -55°C to 200°C. The component is classified as Active product status and maintains full RoHS3 compliance. Substitute parts are identified when original inventory becomes unavailable, when alternative packaging formats are required, or when extended operating temperature ranges are necessary for specific applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MOSX2CT52R2R7J is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 2.7 Ohms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film
• Package configuration: Axial through-hole
• Number of terminations: 2
• RoHS3 compliance status

Acceptable Variation Parameters:

• Operating temperature range (substitute may exceed original range)
• Physical dimensions (substitute may differ within axial package constraints)
• Packaging format (Cut Tape, Bulk, or Tape & Reel)
• Temperature coefficient (when not specified in substitute)
• Flame retardant vs. flame proof designation (both provide safety features)

The RSF200JB-73-2R7 meets all mandatory matching criteria and qualifies as a direct substitute based on electrical equivalence and compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

MOSX2CT52R2R7J Selection Criteria:

• Primary choice when Cut Tape packaging is required for automated assembly processes
• Preferred when compact axial dimensions (4.00mm diameter) are space-constrained
• Specified when KOA Speer Electronics supply chain is established
• Operating temperature ceiling of 200°C is sufficient for application requirements

RSF200JB-73-2R7 Selection Criteria:

• Alternative when bulk packaging format reduces component cost
• Suitable for applications requiring extended operating temperature range up to 235°C
• Acceptable when YAGEO manufacturer qualification is approved
• Larger physical dimensions (5.00mm diameter) must be verified for PCB layout compatibility

Both parts maintain Active product status, full RoHS3 compliance, and REACH unaffected classification. Selection between these equivalents depends on packaging requirements, thermal operating envelope, and established supplier relationships rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can RSF200JB-73-2R7 replace MOSX2CT52R2R7J in all applications?

A: Electrical substitution is valid based on matching resistance, tolerance, power rating, and composition. Physical dimension differences (4.00mm vs. 5.00mm diameter) require PCB layout verification. Packaging format differs (Cut Tape vs. Bulk), affecting assembly process compatibility.

Q: What is the significance of the extended temperature range in RSF200JB-73-2R7?

A: The RSF200JB-73-2R7 operates to 235°C versus 200°C for the MOSX2CT52R2R7J. This extended range provides thermal margin for applications approaching the original part's temperature limit. Applications operating below 200°C experience no functional difference.

Q: Are flame retardant and flame proof designations equivalent?

A: Both designations indicate safety features meeting relevant standards. Flame retardant coating and flame proof construction provide different mechanisms of fire resistance. Application-specific safety requirements determine which designation is necessary.

Q: Does packaging format affect electrical performance?

A: No. Cut Tape and Bulk packaging formats contain identical electrical components. Packaging selection impacts supply chain logistics, assembly automation compatibility, and inventory management rather than component performance.

Q: Are both parts suitable for high-reliability applications?

A: Both parts maintain RoHS3 compliance and REACH unaffected status. Active product status indicates ongoing manufacturer support. Specific reliability requirements (failure rate specifications, qualification testing) are not provided in component data and must be evaluated through application-specific requirements.

Q: What physical space considerations apply when substituting these parts?

A: The RSF200JB-73-2R7 is larger (5.00mm diameter x 15.50mm length) compared to MOSX2CT52R2R7J (4.00mm diameter x 12.00mm length). PCB layout, component spacing, and thermal management must accommodate the larger substitute dimensions.
