Substitute Part Grouping Explanation

Substitution eligibility for the PSP400JB-15R is determined by the following critical parameters:

• Resistance value: 15 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 4W (exact match required)
• Composition: Wirewound (exact match required)
• Operating temperature range: -55°C ~ 350°C (exact match or wider range acceptable)
• Package compatibility: Axial or axial-compatible form factors
• Regulatory compliance: ROHS3 Compliant status maintained

The substitute part SBCHE415RJ meets all critical electrical parameters and maintains regulatory compliance, making it a direct functional equivalent for the PSP400JB-15R in applications where the specified electrical and thermal characteristics are required.

Parameter Comparison

Engineering Selection Recommendations

Both the PSP400JB-15R and SBCHE415RJ are active production components with ROHS3 compliance and identical electrical specifications. Selection between these parts should be based on:

• Physical space constraints: The PSP400JB-15R has a smaller cross-sectional profile (6.40mm square) compared to the SBCHE415RJ (8.00mm x 7.00mm rectangular). PCB layout requirements may dictate which form factor is suitable.
• Package form factor availability: The SBCHE415RJ offers both axial and radial-formed options, providing additional flexibility for circuit board integration.
• Inventory and lead time: Verify current stock levels with your supplier, as availability may influence component selection timing.
• Thermal management: Both parts operate across the full -55°C to 350°C range with identical power dissipation characteristics.

Frequently Asked Questions (FAQ)

Q: Can SBCHE415RJ be used as a direct replacement for PSP400JB-15R?

A: Yes. Both components share identical electrical specifications: 15 Ohm resistance, ±5% tolerance, 4W power rating, wirewound composition, and -55°C to 350°C operating temperature range. Both are ROHS3 compliant. Physical dimensions differ slightly, so verify PCB layout compatibility before substitution.

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

A: The primary differences are physical dimensions and package form factor options. The PSP400JB-15R is a standard axial component with a 6.40mm square cross-section. The SBCHE415RJ offers both axial and radial-formed configurations with an 8.00mm x 7.00mm rectangular profile. The SBCHE415RJ also specifies a temperature coefficient of ±400ppm/°C, whereas the PSP400JB-15R does not provide this specification.

Q: Are there any compatibility concerns when substituting these parts?

A: Compatibility is determined by PCB footprint and lead spacing. Verify that the axial lead length (20.00mm for both parts) and cross-sectional dimensions fit your circuit board layout. If the application uses radial-formed leads, the SBCHE415RJ radial option may be required.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both PSP400JB-15R and SBCHE415RJ are ROHS3 compliant with ECCN classification EAR99 and HTSUS code 8533.21.0080. Both carry MSL ratings appropriate for their respective packaging specifications.

Q: Which part should I select for new designs?

A: Selection should be based on component availability, PCB layout constraints, and supplier lead times. Both parts are functionally equivalent for applications requiring 15 Ohm, 4W wirewound resistors with the specified operating temperature range. Verify current inventory status with your authorized distributor.
