Substitute Part Grouping Explanation

Substitution eligibility for the RR02J510RTB is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 510 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 2W (exact match required)
• Composition: Metal Film (exact match required)

Mechanical Compatibility Requirements:

• Package type: Axial (exact match required)
• Number of terminations: 2 (exact match required)
• Physical dimensions: Compatible with standard axial footprints

Regulatory & Compliance Requirements:

• RoHS3 Compliance (mandatory)
• REACH Unaffected status (mandatory)
• ECCN classification: EAR99 (maintained across substitutes)

The FMP200JR-52-510R from YAGEO meets all electrical and mechanical equivalence criteria, maintaining identical resistance, tolerance, power rating, composition, and axial package configuration.

Engineering Selection Recommendations

Primary Part Selection: The RR02J510RTB remains the preferred selection when available. This part is Active status with established supply inventory and operates across an extended temperature range of -55°C to 235°C, providing broader thermal performance envelope for demanding applications.

Substitute Part Selection: The FMP200JR-52-510R from YAGEO is electrically and mechanically equivalent for applications operating within the -55°C to 155°C temperature range. Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment. The substitute part carries higher inventory availability (9983 units) and maintains identical electrical specifications.

Application Considerations: Selection between these parts depends on application temperature requirements. Applications requiring operation above 155°C must use the RR02J510RTB. Applications within the -55°C to 155°C range may use either part interchangeably from an electrical and regulatory standpoint. Physical dimensions differ slightly in diameter (3.50mm versus 3.90mm), which may affect board layout in space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Are the RR02J510RTB and FMP200JR-52-510R electrically identical?

A: Yes. Both parts provide 510 Ohms ±5% at 2W power rating with metal film composition. Electrical performance is equivalent for applications within the overlapping temperature range of -55°C to 155°C.

Q: What is the primary difference between these two parts?

A: The maximum operating temperature differs. The RR02J510RTB operates to 235°C, while the FMP200JR-52-510R operates to 155°C. Additionally, the physical diameter varies slightly (3.50mm versus 3.90mm), though both maintain the same 9.00mm length.

Q: Can I use the FMP200JR-52-510R in place of the RR02J510RTB in all applications?

A: The FMP200JR-52-510R is suitable for applications operating within -55°C to 155°C. Applications requiring higher temperature operation must use the RR02J510RTB.

Q: Are both parts RoHS compliant?

A: Yes. Both the RR02J510RTB and FMP200JR-52-510R are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: Will the dimensional difference affect PCB layout?

A: The diameter difference (3.50mm versus 3.90mm) is minimal and typically accommodated by standard axial resistor footprints. However, space-constrained designs should verify clearance with the specific PCB layout.

Q: What is the MSL rating for each part?

A: The RR02J510RTB has MSL Not Applicable. The FMP200JR-52-510R has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for either part.
