Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MOSX2CT52RR68J is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 680 mOhms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film

Mechanical Compatibility Requirements:

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

Regulatory & Compliance Requirements:

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

Substitute parts must satisfy all three requirement categories to ensure direct functional and mechanical interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the MOSX2CT52RR68J and RSF200JB-73-0R68 are active production components with identical electrical specifications and axial through-hole mechanical compatibility. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for modern electronics manufacturing.

The RSF200JB-73-0R68 substitute provides an extended operating temperature range to 235°C compared to the primary part's 200°C maximum, offering enhanced thermal performance in high-temperature applications. Physical dimensions differ between the two parts, with the YAGEO substitute featuring a larger diameter and length. Circuit board layout and mechanical clearance must accommodate these dimensional differences during component placement.

Selection between these parts should be based on application-specific requirements including thermal environment, available board space, and supply chain considerations. Both parts satisfy the core electrical and mechanical requirements for direct substitution in 2-watt, 680 mOhm axial resistor applications.

Frequently Asked Questions (FAQ)

Q: Can the RSF200JB-73-0R68 be used as a direct replacement for the MOSX2CT52RR68J?

A: Yes, the RSF200JB-73-0R68 is electrically and mechanically compatible as a substitute. Both parts share identical resistance (680 mOhms), tolerance (±5%), power rating (2W), composition (metal oxide film), and axial package configuration. Physical dimensions differ, requiring verification of available board space during installation.

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

A: The primary differences are manufacturer (KOA Speer versus YAGEO), operating temperature maximum (200°C versus 235°C), physical dimensions (4.00mm x 12.00mm versus 5.00mm x 15.50mm), and packaging format (cut tape versus bulk). Electrical performance and regulatory compliance are equivalent.

Q: Are there any temperature-related limitations when substituting these parts?

A: The MOSX2CT52RR68J operates to 200°C maximum, while the RSF200JB-73-0R68 operates to 235°C. In applications where operating temperature exceeds 200°C, the YAGEO substitute provides extended thermal capability. For applications below 200°C, both parts perform identically.

Q: Do the different physical dimensions affect circuit board design?

A: Yes. The RSF200JB-73-0R68 is larger (5.00mm diameter x 15.50mm length) compared to the MOSX2CT52RR68J (4.00mm diameter x 12.00mm length). Circuit board layout must accommodate the larger substitute component. Verify clearance to adjacent components and board edge before substitution.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the MOSX2CT52RR68J and RSF200JB-73-0R68 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronics manufacturing and distribution.

Q: What is the difference between cut tape and bulk packaging?

A: The MOSX2CT52RR68J is supplied in cut tape packaging, suitable for automated pick-and-place assembly. The RSF200JB-73-0R68 is supplied in bulk packaging, typically used for manual assembly or alternative handling processes. Packaging format does not affect electrical or mechanical performance.
