Substitute Part Grouping Explanation

Substitution eligibility for the CPCP1010R00JB321 is determined by strict equivalence across the following parameters:

• Resistance value: 10 Ohms
• Tolerance: ±5%
• Power rating: 10W
• Composition: Wirewound
• Package configuration: Radial
• Operating temperature range: -65°C to 275°C
• Temperature coefficient: ±20ppm/°C
• Physical dimensions: 0.633" L x 0.485" W (16.08mm x 12.32mm)
• Height - Seated (Max): 1.372" (34.85mm)
• Number of terminations: 2

The CPCP1010R00JE31 meets all these criteria and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both CPCP1010R00JB321 and CPCP1010R00JE31 are active production parts from Vishay Dale with identical electrical and mechanical specifications. The primary distinction is RoHS compliance status: CPCP1010R00JB321 is RoHS non-compliant, while CPCP1010R00JE31 is ROHS3 compliant. Selection between these parts should be based on regulatory requirements applicable to the end application. For applications requiring RoHS3 compliance, CPCP1010R00JE31 is the appropriate selection. Both parts maintain equivalent performance across all critical parameters including resistance, tolerance, power rating, temperature range, and physical dimensions.

Frequently Asked Questions (FAQ)
