Substitute Part Grouping Explanation

Substitution of the MO2C201J is based on strict equivalence of the following critical parameters:

• Resistance Value: 200 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power Rating: 2W (exact match required)
• Composition: Metal Oxide Film (exact match required)
• Package Type: Axial (exact match required)
• Operating Temperature Range: -55°C to 200°C (exact match required)
• Features: Flame Retardant Coating, Safety (exact match required)
• Regulatory Compliance: ROHS3 Compliant (exact match required)

The substitute part MOS2CT52R201J meets all critical electrical and mechanical parameters. While minor variations exist in physical dimensions and temperature coefficient, these do not affect functional equivalence in standard circuit applications. The substitute part maintains active product status, ensuring long-term availability and supply chain reliability.

Engineering Selection Recommendations

The MOS2CT52R201J is the primary substitute for the obsolete MO2C201J. Selection of this substitute is based on the following engineering criteria:

Electrical Equivalence: The substitute part maintains identical resistance value, tolerance, power rating, and operating temperature range. These parameters ensure functional compatibility in all circuit applications where the original part was specified.

Regulatory Compliance: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and safety standards. No additional compliance verification is required.

Product Status: The substitute part carries active product status, ensuring availability for current and future procurement cycles. The obsolete status of the original part makes transition to an active equivalent necessary for design continuity.

Physical Considerations: The substitute part features reduced physical dimensions (4.00mm x 12.00mm versus 6.00mm x 15.50mm). PCB layout verification is required to confirm that the smaller form factor accommodates existing footprint designs. Both parts maintain axial package configuration and identical termination count.

Temperature Coefficient Variance: The substitute part exhibits a temperature coefficient of ±300ppm/°C compared to ±200ppm/°C for the original part. This variance remains within acceptable limits for standard resistor applications and does not compromise circuit performance in typical operating conditions.

Frequently Asked Questions (FAQ)

Q: Can MOS2CT52R201J be used as a direct replacement for MO2C201J?

A: Yes. The substitute part maintains identical electrical specifications including resistance value, tolerance, power rating, composition, and operating temperature range. Both parts are ROHS3 compliant and feature identical safety characteristics.

Q: What is the primary difference between these parts?

A: The main differences are product status (obsolete versus active), physical dimensions, and temperature coefficient. The substitute part is smaller and exhibits a slightly higher temperature coefficient (±300ppm/°C versus ±200ppm/°C). These differences do not affect functional equivalence in standard circuit applications.

Q: Are there any PCB layout considerations when switching to MOS2CT52R201J?

A: Yes. The substitute part is physically smaller (4.00mm x 12.00mm versus 6.00mm x 15.50mm). PCB footprint and component spacing must be verified to accommodate the reduced dimensions. Both parts maintain axial configuration and identical lead termination count.

Q: Is the higher temperature coefficient of the substitute part a concern?

A: The temperature coefficient difference (±300ppm/°C versus ±200ppm/°C) is within acceptable limits for standard resistor applications. Circuit performance impact is negligible in typical operating conditions. Applications requiring precise temperature stability should conduct specific thermal analysis.

Q: What is the packaging difference between these parts?

A: MO2C201J is supplied in standard packaging, while MOS2CT52R201J is supplied in Cut Tape (CT) packaging. Both parts are identical in electrical and mechanical specifications. Packaging format affects procurement and handling procedures only.

Q: Why is the original part obsolete?

A: The MO2C201J is classified as obsolete by the manufacturer. The MOS2CT52R201J represents the active equivalent, ensuring continued availability and supply chain reliability for this resistance value and power rating.
