Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MOSX2CT52R7R5J is determined by the following critical parameters:

• Resistance value: 7.5 Ohms (exact match required)
• Tolerance: ±5% (electrical performance equivalence)
• Power rating: 2W (thermal capability match)
• Composition: Metal Oxide Film (material consistency)
• Package: Axial through-hole (mechanical compatibility)
• RoHS compliance: ROHS3 Compliant (regulatory requirement)

The RSF200JB-73-7R5 manufactured by YAGEO meets all substitution criteria. Both parts share identical electrical specifications (7.5 Ohms, ±5%, 2W) and composition (metal oxide film). Both are ROHS3 compliant and feature axial through-hole packaging suitable for identical PCB mounting applications.

Parameter Comparison

Engineering Selection Recommendations

Both the MOSX2CT52R7R5J and RSF200JB-73-7R5 are active production parts with ROHS3 compliance and unlimited moisture sensitivity ratings. Selection between these parts is based on application-specific requirements:

The MOSX2CT52R7R5J offers a reduced-size form factor (4.00mm x 12.00mm) with a maximum operating temperature of 200°C and flame retardant coating. The RSF200JB-73-7R5 provides an extended operating temperature range to 235°C with flame proof characteristics and larger physical dimensions (5.00mm x 15.50mm). Both parts deliver equivalent electrical performance for 7.5 Ohm, 2W applications and are suitable for direct substitution where physical space and thermal requirements align.

Frequently Asked Questions (FAQ)

Q: Can the RSF200JB-73-7R5 directly replace the MOSX2CT52R7R5J in existing designs?

A: Yes, the RSF200JB-73-7R5 is electrically equivalent with identical resistance (7.5 Ohms), tolerance (±5%), and power rating (2W). Both use metal oxide film composition and axial through-hole packaging. Physical dimensions differ; verify PCB layout accommodates the larger RSF200JB-73-7R5 form factor (5.00mm x 15.50mm versus 4.00mm x 12.00mm).

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

A: The primary differences are physical size and maximum operating temperature. The MOSX2CT52R7R5J is a reduced-size component rated to 200°C, while the RSF200JB-73-7R5 is larger and rated to 235°C. Both meet ROHS3 compliance and feature flame protection (retardant versus proof).

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

A: The MOSX2CT52R7R5J operates to 200°C maximum, while the RSF200JB-73-7R5 extends to 235°C. Selection depends on specific thermal requirements. Both parts maintain performance within their respective operating ranges.

Q: Do packaging differences affect circuit performance?

A: No. Both parts use identical axial through-hole packaging suitable for standard PCB mounting. Physical dimensions differ but do not affect electrical characteristics. Verify available PCB space before selection.

Q: Are both parts RoHS compliant?

A: Yes. Both the MOSX2CT52R7R5J and RSF200JB-73-7R5 are ROHS3 compliant with moisture sensitivity level 1 (unlimited).
