Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CB10JB47R0 is determined by the following critical parameters:

• Resistance value: 47 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 10W (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 SQPW1047RJ from TE Connectivity Passive Product meets all substitution criteria with identical electrical specifications and equivalent mechanical form factor.

Parameter Comparison

Engineering Selection Recommendations

Both the CB10JB47R0 and SQPW1047RJ are active production components with full ROHS3 compliance and REACH unaffected status. The SQPW1047RJ offers higher inventory availability at 3377 units compared to 745 units for the CB10JB47R0. Both components carry identical EAR99 export classification and HTSUS coding (8533.21.0080).

The primary difference between these parts is the maximum operating temperature: the CB10JB47R0 operates to 275°C while the SQPW1047RJ operates to 250°C. Additionally, the SQPW1047RJ exhibits a higher temperature coefficient of ±300ppm/°C compared to ±200ppm/°C for the CB10JB47R0. These differences should be evaluated against specific application thermal requirements.

Frequently Asked Questions (FAQ)

Q: Can SQPW1047RJ replace CB10JB47R0 in all applications?

A: The SQPW1047RJ is electrically and mechanically equivalent for applications operating within -55°C to 250°C. Applications requiring operation above 250°C or demanding tighter temperature coefficient performance should retain the CB10JB47R0.

Q: Are the physical dimensions compatible?

A: Both parts use axial through-hole packaging with 2 terminations. The CB10JB47R0 measures 0.374" square × 1.890" length, while the SQPW1047RJ measures 0.394" × 0.354" rectangular × 1.890" length. Both fit standard axial component footprints.

Q: What regulatory certifications apply to both parts?

A: Both CB10JB47R0 and SQPW1047RJ are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes.

Q: Why would I choose one part over the other?

A: Select CB10JB47R0 for applications requiring extended temperature operation to 275°C or superior temperature stability. Select SQPW1047RJ when higher inventory availability is advantageous and operating conditions remain within -55°C to 250°C.
