Key Parameters

Substitute Part Grouping Explanation

Substitution of the MO2C272J is determined by strict equivalence across the following critical parameters:

• Resistance Value: 2.7 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power Rating: 2W (exact match required)
• Composition: Metal Oxide Film (exact match required)
• Package Configuration: Axial through-hole (exact match required)
• Operating Temperature Range: -55°C ~ 200°C (exact match required)
• Regulatory Compliance: ROHS3 Compliant and REACH Unaffected (exact match required)

The MOS2CT52R272J qualifies as a direct substitute based on identical electrical specifications and regulatory compliance. Physical dimensions differ between the main part and substitute, reflecting design evolution within the same product family while maintaining functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The MOS2CT52R272J is the active equivalent substitute for the obsolete MO2C272J. Both components are manufactured by KOA Speer Electronics, Inc., and maintain identical electrical specifications including resistance value, tolerance, power rating, and operating temperature range. Both components satisfy ROHS3 compliance and REACH unaffected status requirements.

The MOS2CT52R272J is currently in active production status with confirmed inventory availability, whereas the MO2C272J is obsolete. Selection of the MOS2CT52R272J ensures continued access to equivalent functionality with modern supply chain support.

Physical dimensions differ between the two parts. The MOS2CT52R272J features a smaller axial package (4.00mm diameter x 12.00mm length) compared to the MO2C272J (6.00mm diameter x 15.50mm length). Temperature coefficient specification differs at ±300ppm/°C for the MOS2CT52R272J versus ±200ppm/°C for the MO2C272J. These variations remain within acceptable substitution parameters for metal oxide film resistor applications.

Frequently Asked Questions (FAQ)

Q: Can the MOS2CT52R272J directly replace the MO2C272J in existing designs?

A: The MOS2CT52R272J provides electrical equivalence across all critical parameters: 2.7 kOhms resistance, ±5% tolerance, 2W power rating, metal oxide film composition, and -55°C ~ 200°C operating temperature range. Physical dimensions differ, requiring verification of board layout and mechanical clearance in the specific application.

Q: What is the significance of the different temperature coefficients?

A: The MO2C272J specifies ±200ppm/°C while the MOS2CT52R272J specifies ±300ppm/°C. Both values fall within standard metal oxide film resistor specifications. The difference reflects manufacturing process variations between the obsolete and active product lines. Selection depends on circuit-level temperature stability requirements.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the MO2C272J and MOS2CT52R272J are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What packaging format is the MOS2CT52R272J supplied in?

A: The MOS2CT52R272J is supplied in Cut Tape (CT) packaging, suitable for automated assembly processes. The MO2C272J packaging format is not specified in available documentation.

Q: Why are the physical dimensions different between these parts?

A: The MOS2CT52R272J represents a newer design iteration within the KOA Speer MOS series, featuring a more compact axial package (4.00mm x 12.00mm) compared to the older MO2C272J (6.00mm x 15.50mm). Both maintain identical electrical performance and safety characteristics while the newer design offers space efficiency benefits.

Q: Is the MO2C272J still available for purchase?

A: The MO2C272J is classified as obsolete. The MOS2CT52R272J is the active production equivalent with confirmed inventory availability from KOA Speer Electronics, Inc.
