Parameter Comparison

Engineering Selection Recommendations

Both the PSP7WSJB-15R and SBCHE615RJ maintain Active product status with full ROHS3 compliance and EAR99 export classification. Selection between these parts should be based on:

• PCB layout constraints: The SBCHE615RJ offers radial-formed lead options in addition to standard axial configuration, providing flexibility for space-constrained designs
• Supply chain availability: PSP7WSJB-15R has 1062 units in stock; SBCHE615RJ has 869 units available
• Thermal management requirements: Both parts support the full -55°C ~ 350°C operating range
• Regulatory compliance: Both parts satisfy ROHS3 and maintain identical HTSUS classification for procurement purposes

Frequently Asked Questions (FAQ)

Q: Can SBCHE615RJ replace PSP7WSJB-15R in existing designs?

A: Yes. Both parts share identical electrical specifications (15 Ohms, ±5%, 7W) and operate across the same temperature range (-55°C ~ 350°C). The SBCHE615RJ's radial-formed lead option may require PCB layout verification if the original design uses standard axial spacing.

Q: What are the physical dimension differences?

A: PSP7WSJB-15R measures 0.354" Square x 0.984" L (9.00mm x 25.00mm). SBCHE615RJ measures 0.315" x 0.276" Rectangular x 1.496" L (8.00mm x 7.00mm x 38.00mm). The SBCHE615RJ is longer but has a smaller cross-sectional footprint, affecting board layout placement.

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

A: Yes. Both parts are rated for continuous operation up to 350°C, meeting the full operating temperature specification.

Q: What is the tolerance matching requirement?

A: Both parts maintain ±5% tolerance, ensuring equivalent circuit performance in applications where resistance accuracy is critical.

Q: Do both parts have identical moisture sensitivity?

A: PSP7WSJB-15R has MSL 1 (Unlimited). SBCHE615RJ lists MSL as Not Applicable. Both are suitable for standard storage and handling conditions.
