Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MOS2CT52R271J is determined by matching the following critical parameters:

Electrical Parameters (Mandatory Match):

• Resistance value: 270 Ohms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film

Mechanical Parameters (Mandatory Match):

• Package configuration: Axial through-hole

Compliance Parameters (Mandatory Match):

• RoHS3 Compliance status

The substitute part RSF200JB-73-270R from YAGEO meets all mandatory electrical and mechanical criteria. Both parts are metal oxide film axial resistors with identical resistance, tolerance, and power specifications. Both are ROHS3 compliant and REACH unaffected. Physical dimensions differ between the two parts; however, both are axial through-hole configurations suitable for standard PCB mounting applications where axial component spacing accommodates the dimensional variance.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: MOS2CT52R271J

The MOS2CT52R271J remains the specified component with Active product status and established supply availability (1561 pieces in stock). This part is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Substitute Part: RSF200JB-73-270R

The RSF200JB-73-270R from YAGEO is electrically and mechanically equivalent for applications requiring a 270 Ohm ±5% 2W axial metal oxide film resistor. This substitute is also ROHS3 compliant and REACH unaffected. The substitute offers extended operating temperature capability (-55°C ~ 235°C versus -55°C ~ 200°C), providing additional thermal margin in high-temperature applications. Physical dimensions are larger; design layouts must accommodate the increased size (5.00mm diameter x 15.50mm length versus 4.00mm diameter x 12.00mm length). The substitute is available in bulk packaging format with higher inventory availability (8413 pieces in stock).

Selection between these parts depends on design constraints related to physical space, packaging requirements, and supply chain considerations. Both parts satisfy identical electrical specifications and compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can RSF200JB-73-270R replace MOS2CT52R271J in all applications?

A: RSF200JB-73-270R is electrically equivalent for applications requiring 270 Ohm ±5% 2W axial metal oxide film resistors. Physical dimensions differ; PCB layout must accommodate the larger component size (5.00mm diameter x 15.50mm length). Both parts meet identical electrical specifications and compliance standards.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (KOA Speer versus YAGEO), physical dimensions, operating temperature upper limit (200°C versus 235°C), and packaging format (cut tape versus bulk). Electrical specifications, tolerance, power rating, and composition are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both MOS2CT52R271J and RSF200JB-73-270R are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: Does the larger size of RSF200JB-73-270R affect performance?

A: Physical size does not affect electrical performance. Both parts are metal oxide film axial resistors with identical resistance, tolerance, and power specifications. Size differences relate only to mechanical packaging and PCB layout considerations.

Q: What is the temperature coefficient difference between these parts?

A: MOS2CT52R271J specifies ±300ppm/°C temperature coefficient. RSF200JB-73-270R temperature coefficient data is not provided in available specifications. Both parts operate across overlapping temperature ranges with RSF200JB-73-270R rated to 235°C maximum.

Q: Can I use these parts interchangeably in existing designs?

A: Electrical interchangeability is confirmed. Mechanical interchangeability depends on PCB layout constraints. The RSF200JB-73-270R requires additional space due to larger dimensions. Verify PCB footprint and component spacing before substitution.

Q: Which part should I select for new designs?

A: Selection depends on design requirements and supply chain strategy. Both parts meet identical electrical and compliance specifications. Consider physical space availability, packaging preferences (cut tape versus bulk), and long-term supply availability when making selection decisions.
