Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CB10JB4R70 is determined by the following critical parameters:

• Resistance value: 4.7 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 (exact match required)
• Regulatory compliance: ROHS3 compliant (minimum requirement)

The substitute part SQPW104R7J from TE Connectivity Passive Product meets all critical electrical and mechanical parameters. Both parts share identical resistance, tolerance, power rating, composition, and axial package configuration. Both components maintain flame-proof and moisture-resistant characteristics with ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the CB10JB4R70 and SQPW104R7J are active production components with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on application-specific requirements:

The CB10JB4R70 provides a maximum operating temperature of 275°C with a temperature coefficient of ±200ppm/°C, suitable for high-temperature applications requiring tighter thermal stability.

The SQPW104R7J operates to 250°C with a temperature coefficient of ±300ppm/°C and offers higher inventory availability at 2047 units in stock.

Both components are certified for flame-proof and moisture-resistant operation with identical electrical specifications. Physical dimensions differ slightly between manufacturers, with the CB10JB4R70 measuring 0.374" square by 1.890" length and the SQPW104R7J measuring 0.394" by 0.354" rectangular by 1.890" length. PCB layout and mounting clearance requirements should be evaluated for the specific application.

Frequently Asked Questions (FAQ)

Q: Can SQPW104R7J replace CB10JB4R70 in all applications?

A: Both parts share identical resistance, tolerance, power rating, and axial package configuration. The primary differences are operating temperature range (CB10JB4R70 to 275°C versus SQPW104R7J to 250°C) and temperature coefficient (±200ppm/°C versus ±300ppm/°C). Applications operating above 250°C or requiring temperature coefficient better than ±300ppm/°C must use the CB10JB4R70.

Q: Are there physical dimension differences between these parts?

A: Yes. The CB10JB4R70 has a square cross-section of 0.374" with 1.890" length. The SQPW104R7J has a rectangular cross-section of 0.394" by 0.354" with 1.890" length. Both are axial through-hole packages. PCB layout and mounting clearance must accommodate the specific physical profile.

Q: Do both parts meet the same regulatory requirements?

A: Both CB10JB4R70 and SQPW104R7J are ROHS3 compliant and REACH unaffected. Both carry EAR99 ECCN classification and 8533.21.0080 HTSUS code.

Q: Which part should be selected for new designs?

A: Selection depends on application temperature requirements and thermal stability needs. For applications requiring operation to 275°C or tighter temperature coefficient performance, specify CB10JB4R70. For general-purpose applications with adequate inventory, SQPW104R7J is acceptable.
