Substitute Part Grouping Explanation

Substitution eligibility for the CB10JB68R0 is determined by the following critical parameters:

• Resistance value: 68 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)
• Features: Flame proof and moisture resistant construction (required)
• Regulatory compliance: ROHS3 compliant (required)

The SQPW1068RJ from TE Connectivity Passive Product meets all substitution criteria with identical electrical specifications and equivalent mechanical construction.

Parameter Comparison

Engineering Selection Recommendations

Both CB10JB68R0 and SQPW1068RJ are active production components with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on application-specific requirements:

The CB10JB68R0 provides a wider operating temperature range (-55°C to 275°C) and lower temperature coefficient (±200ppm/°C), making it suitable for high-temperature applications requiring greater thermal stability.

The SQPW1068RJ from TE Connectivity offers equivalent electrical and mechanical performance with higher inventory availability (3068 units in stock). The operating temperature range extends to 250°C, which covers most standard industrial applications.

Both components satisfy identical regulatory and compliance requirements for ROHS3 and REACH standards.

Frequently Asked Questions (FAQ)

Q: Can SQPW1068RJ directly replace CB10JB68R0 in all applications?

A: Direct substitution is valid for applications operating within -55°C to 250°C. Applications requiring operation above 250°C must use the CB10JB68R0 due to its extended temperature range to 275°C.

Q: What is the significance of the temperature coefficient difference?

A: The CB10JB68R0 has a temperature coefficient of ±200ppm/°C compared to ±300ppm/°C for SQPW1068RJ. In applications with strict resistance stability requirements across temperature variations, the lower coefficient of the CB10JB68R0 provides superior performance.

Q: Are the physical dimensions compatible?

A: Both components use axial through-hole packaging with 1.890" lead length. The CB10JB68R0 has a 0.374" square cross-section, while SQPW1068RJ has a 0.394" x 0.354" rectangular cross-section. Both fit standard axial component footprints.

Q: Do both parts meet the same safety and environmental standards?

A: Yes. Both CB10JB68R0 and SQPW1068RJ are ROHS3 compliant and REACH unaffected, with identical flame-proof and moisture-resistant safety features.

Q: Which part should be selected for new designs?

A: Selection depends on thermal requirements and supply chain considerations. For applications requiring maximum temperature stability and extended operating range, specify CB10JB68R0. For standard industrial applications with higher availability, SQPW1068RJ is suitable.
