Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MOSX2CT52RR75J is determined by the following critical parameters:

• Resistance Value: 750 mOhms (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: Minimum -55°C to maximum 200°C or higher
• RoHS Compliance: ROHS3 Compliant (required)
• Moisture Sensitivity Level: 1 (Unlimited) or equivalent

The RSF200JB-73-0R75 manufactured by YAGEO meets all critical substitution criteria and qualifies as an equivalent part.

Parameter Comparison

Engineering Selection Recommendations

Both the MOSX2CT52RR75J and RSF200JB-73-0R75 are active production parts with ROHS3 compliance and MSL 1 (Unlimited) ratings. The RSF200JB-73-0R75 provides an extended operating temperature range to 235°C compared to the original part's 200°C maximum. Physical dimensions differ between the two parts; the YAGEO substitute is larger in both diameter and length. Component selection should account for available board space and thermal requirements specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the RSF200JB-73-0R75 be used as a direct replacement for the MOSX2CT52RR75J?

A: Yes, the RSF200JB-73-0R75 meets all critical electrical specifications: 750 mOhms resistance, ±5% tolerance, 2W power rating, metal oxide film composition, and axial package type. Both parts are ROHS3 compliant with MSL 1 ratings. Physical dimensions differ, requiring verification of available board space.

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

A: The primary differences are operating temperature range (MOSX2CT52RR75J: -55°C to 200°C; RSF200JB-73-0R75: -55°C to 235°C) and physical dimensions (KOA: 4.00mm x 12.00mm; YAGEO: 5.00mm x 15.50mm). Electrical performance is equivalent.

Q: Are there packaging differences between the original and substitute?

A: The MOSX2CT52RR75J is supplied in tape & reel packaging, while the RSF200JB-73-0R75 is supplied in bulk packaging. Both are suitable for through-hole assembly applications.

Q: Do both parts meet the same compliance standards?

A: Yes, both the MOSX2CT52RR75J and RSF200JB-73-0R75 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What should be considered when selecting between these parts?

A: Selection should be based on available board space (due to dimensional differences), required operating temperature range, and packaging requirements. The YAGEO substitute offers a higher maximum operating temperature if thermal headroom is a design consideration.
