Substitute Part Grouping Explanation

Substitution eligibility for the CB7JB10R0 is determined by the following critical parameters:

• Resistance value: 10 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)
• Features: Flame Proof, Moisture Resistant, Safety (exact match required)
• Compliance: ROHS3 Compliant (exact match required)

The SQPW710RJ from TE Connectivity Passive Product meets all substitution criteria, maintaining identical electrical specifications and safety certifications while offering alternative sourcing.

Parameter Comparison

Engineering Selection Recommendations

Both CB7JB10R0 and SQPW710RJ are Active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The CB7JB10R0 offers a wider operating temperature range (-55°C to 275°C) compared to SQPW710RJ (-55°C to 250°C), making it suitable for applications requiring extended high-temperature performance. The SQPW710RJ exhibits a higher temperature coefficient (±300ppm/°C versus ±200ppm/°C), which may impact precision applications requiring tighter stability across temperature variations. Component selection should be based on specific application temperature requirements and tolerance specifications.

Frequently Asked Questions (FAQ)

Q: Can SQPW710RJ replace CB7JB10R0 in all applications?

A: SQPW710RJ is electrically equivalent for resistance, tolerance, and power rating. However, applications operating above 250°C require CB7JB10R0 due to its extended temperature range. Applications requiring temperature coefficient stability below ±250ppm/°C should use CB7JB10R0.

Q: Are the physical dimensions compatible?

A: Both parts use axial through-hole packaging. CB7JB10R0 dimensions are 0.374" Square x 1.378" L (9.50mm x 35.00mm). SQPW710RJ dimensions are 0.394" x 0.354" Rectangular x 1.378" L (10.00mm x 9.00mm x 35.00mm). While lead length is identical, cross-sectional dimensions differ slightly. PCB layout and thermal management considerations may be affected.

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

A: Yes. Both CB7JB10R0 and SQPW710RJ are ROHS3 compliant, REACH unaffected, and feature flame-proof and moisture-resistant construction with safety certification.

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

A: CB7JB10R0 has a temperature coefficient of ±200ppm/°C, while SQPW710RJ has ±300ppm/°C. This means CB7JB10R0 maintains tighter resistance stability across temperature variations, making it preferable for precision applications.
