Substitute Part Grouping Explanation

Substitution eligibility for the CB5JB27R0 is determined by the following critical parameters:

• Resistance value: 27 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 5W (exact match required)
• Composition: Wirewound (exact match required)
• Package: Axial through-hole (exact match required)
• Features: Flame proof, moisture resistant, safety-rated construction (all required)
• Regulatory compliance: ROHS3 compliant, REACH unaffected (required)

The SQPW527RJ from TE Connectivity Passive Product meets all substitution criteria with identical electrical specifications and equivalent mechanical construction.

Parameter Comparison

Engineering Selection Recommendations

Both CB5JB27R0 and SQPW527RJ are active production components with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• Availability: SQPW527RJ has higher inventory (2767 units) compared to CB5JB27R0 (735 units)
• Packaging format: CB5JB27R0 is supplied in trays; SQPW527RJ is supplied in bulk
• Operating temperature ceiling: CB5JB27R0 supports -55°C to 275°C; SQPW527RJ supports -55°C to 250°C
• Temperature coefficient stability: CB5JB27R0 offers ±200ppm/°C; SQPW527RJ offers ±300ppm/°C

Both parts satisfy identical electrical and mechanical requirements for 27 Ohm 5W axial wirewound resistor applications with flame-proof and moisture-resistant construction.

Frequently Asked Questions (FAQ)

Q: Can SQPW527RJ directly replace CB5JB27R0 in all applications?

A: SQPW527RJ is electrically and mechanically equivalent for standard 27 Ohm 5W axial resistor applications. Applications requiring operation above 250°C or demanding temperature coefficient stability better than ±300ppm/°C should retain CB5JB27R0.

Q: What are the physical dimension differences between these parts?

A: CB5JB27R0 has a square cross-section of 0.374" (9.50mm). SQPW527RJ has a rectangular cross-section of 0.394" x 0.354" (10.00mm x 9.00mm). Both maintain 0.866" (22.00mm) axial length. PCB layout and mounting clearance must accommodate these dimensional variations.

Q: Are both parts compliant with current regulatory requirements?

A: Both CB5JB27R0 and SQPW527RJ are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing and distribution.

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

A: CB5JB27R0 exhibits ±200ppm/°C temperature coefficient while SQPW527RJ exhibits ±300ppm/°C. In precision applications with wide temperature operating ranges, the lower coefficient of CB5JB27R0 provides superior resistance stability across temperature extremes.

Q: How do packaging formats affect component selection?

A: CB5JB27R0 is supplied in trays suitable for automated assembly processes. SQPW527RJ is supplied in bulk format. Selection depends on manufacturing process requirements and inventory management practices.
