Substitute Part Grouping Explanation

Substitution eligibility for the CB7JB47R0 is determined by the following critical parameters:

  • Resistance value: 47 Ohms (exact match required)
  • Tolerance: ±5% (exact match required)
  • Power rating: 7W (exact match required)
  • Composition: Wirewound (exact match required)
  • Package: Axial through-hole (exact match required)
  • Regulatory compliance: ROHS3 Compliant, REACH Unaffected, EAR99 classification (all required)
  • Termination count: 2 (exact match required)

The SQPW747RJ from TE Connectivity Passive Product meets all substitution criteria with identical electrical specifications and regulatory status.

Engineering Selection Recommendations

Both CB7JB47R0 and SQPW747RJ are active production components with ROHS3 compliance and REACH unaffected status. Selection between these parts is based on application requirements and availability:

The CB7JB47R0 provides a maximum operating temperature of 275°C with a temperature coefficient of ±200ppm/°C, suitable for high-temperature applications. The SQPW747RJ operates to 250°C with a temperature coefficient of ±300ppm/°C. For applications requiring the extended upper temperature limit or tighter temperature stability, the CB7JB47R0 is the primary choice. For general-purpose applications within the 250°C operating range, the SQPW747RJ provides equivalent functionality with higher current inventory availability (1900 units in stock).

Frequently Asked Questions (FAQ)

Q: Can SQPW747RJ replace CB7JB47R0 in all applications?

A: SQPW747RJ is electrically equivalent for applications operating at or below 250°C. Applications requiring operation above 250°C or demanding temperature coefficients tighter than ±300ppm/°C require the CB7JB47R0.

Q: Are the physical dimensions compatible between these parts?

A: Both parts use axial through-hole packaging with 2 terminations. The CB7JB47R0 has a square cross-section (0.374" x 9.50mm), while the SQPW747RJ has a rectangular cross-section (0.394" x 0.354" x 10.00mm x 9.00mm). Both are 1.378" (35.00mm) in length. PCB layout and mechanical clearance must be verified for each application.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both CB7JB47R0 and SQPW747RJ are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: What is the difference in temperature coefficient between these parts?

A: The CB7JB47R0 has a temperature coefficient of ±200ppm/°C, while the SQPW747RJ is ±300ppm/°C. This means the CB7JB47R0 maintains tighter resistance stability across temperature variations.
