Key Parameters

Substitute Part Grouping Explanation

Substitution of the MOS2CT52R152J is based on electrical and mechanical parameter equivalence. The following criteria determine valid substitutes:

Electrical Equivalence Requirements:

• Resistance value: 1.5 kOhms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film

Mechanical Equivalence Requirements:

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

Compliance Requirements:

• RoHS3 compliance
• REACH unaffected status
• ECCN classification: EAR99

The RSF200JB-73-1K5 from YAGEO meets all electrical and mechanical equivalence criteria. Physical dimensions differ slightly between the main part and substitute, which is acceptable within industry standards for axial resistor form factors. Operating temperature range extends to 235°C for the substitute, providing enhanced thermal capability.

Parameter Comparison

Engineering Selection Recommendations

Both the MOS2CT52R152J and RSF200JB-73-1K5 are active production components with full RoHS3 compliance and REACH unaffected status. Selection between these parts is determined by application-specific requirements:

Select MOS2CT52R152J when:

• Compact form factor is required (4.00mm diameter, 12.00mm length)
• Cut tape packaging is preferred for automated assembly
• Operating temperature does not exceed 200°C
• Temperature coefficient specification of ±300ppm/°C is required

Select RSF200JB-73-1K5 when:

• Extended operating temperature capability to 235°C is required
• Larger physical dimensions are acceptable (5.00mm diameter, 15.50mm length)
• Bulk packaging format is compatible with procurement workflow
• Higher inventory availability is prioritized (12,528 pieces in stock)

Both parts satisfy identical electrical specifications and regulatory requirements. Physical dimension differences are within acceptable tolerances for axial resistor applications and do not affect electrical performance.

Frequently Asked Questions (FAQ)

Q: Can RSF200JB-73-1K5 be used as a direct replacement for MOS2CT52R152J in existing designs?

A: Electrical substitution is valid. The RSF200JB-73-1K5 provides identical resistance, tolerance, power rating, and composition. Physical dimensions differ; verify that the larger form factor (5.00mm diameter x 15.50mm length versus 4.00mm diameter x 12.00mm length) accommodates board layout and spacing constraints.

Q: What is the significance of the operating temperature range difference?

A: The MOS2CT52R152J operates from -55°C to 200°C, while the RSF200JB-73-1K5 extends to 235°C. For applications operating within the -55°C to 200°C range, both parts perform identically. Applications requiring operation above 200°C require the RSF200JB-73-1K5.

Q: Are packaging differences between Cut Tape and Bulk significant for component selection?

A: Packaging format affects procurement and assembly processes but not electrical performance. Cut Tape (CT) packaging is optimized for automated pick-and-place assembly. Bulk packaging requires manual handling or reel conversion. Select based on manufacturing process requirements.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both MOS2CT52R152J and RSF200JB-73-1K5 are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: What is the impact of the temperature coefficient specification?

A: The MOS2CT52R152J specifies ±300ppm/°C temperature coefficient. The RSF200JB-73-1K5 does not provide this specification in available data. For applications requiring precise temperature coefficient control, the MOS2CT52R152J is the specified selection.

Q: Can these parts be used interchangeably in high-reliability applications?

A: Both parts are active production components with equivalent electrical specifications. Interchangeability in high-reliability applications depends on design qualification requirements. Consult design documentation and qualification procedures for specific application requirements.
