Key Parameters

Substitute Part Grouping Explanation

The CB2JB1R60 qualifies as a direct substitute based on the following critical parameters:

• Identical resistance value: 1.6 Ohms
• Matching tolerance: ±5%
• Equivalent power rating: 2W
• Same composition: Wirewound
• Identical package type: Axial
• Matching feature set: Flame Proof, Moisture Resistant, Safety
• Both parts are ROHS3 compliant and REACH unaffected

The CB2JB1R60 is manufactured by the same supplier (Stackpole Electronics Inc) and maintains active product status, making it suitable for replacing the obsolete WRF2JB1R60 in applications requiring these electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The CB2JB1R60 is the direct equivalent for WRF2JB1R60 replacement. Both parts meet identical electrical specifications (1.6 Ohms, ±5%, 2W) and maintain the same safety and environmental features. The CB2JB1R60 offers an extended operating temperature range (-55°C ~ 275°C versus -55°C ~ 200°C) and improved temperature coefficient stability (±200ppm/°C versus -80/+900ppm/°C), providing enhanced performance margins in thermal environments.

Physical dimensions differ slightly; the CB2JB1R60 is larger (0.252" Square x 0.709" L versus 0.197" Dia x 0.630" L). PCB layout and mounting clearance must be verified for space-constrained applications. Both parts are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance for industrial and safety-critical deployments.

Frequently Asked Questions (FAQ)
