CPCP1020R00JB321 Equivalent & Substitute Parts

Part Overview

The CPCP1020R00JB321 is a 20 Ohm, 10W through-hole wirewound resistor manufactured by Vishay Dale. This radial flame-proof, non-inductive safety resistor is designed for applications requiring high power dissipation with tight tolerance specifications. The part is currently active in production with 626 units in stock. Substitute parts are necessary when the primary part becomes unavailable or when design requirements mandate alternative compliance certifications such as RoHS compliance.

Substitute Part Grouping Explanation

The CPCP1020R00JE31 qualifies as a parametric equivalent to the CPCP1020R00JB321 based on the following matching electrical and mechanical specifications:

• Resistance value: 20 Ohms
• Tolerance: ±5%
• Power rating: 10W
• Composition: Wirewound
• Package: Radial
• Temperature coefficient: ±20ppm/°C
• Operating temperature range: -65°C to 275°C
• Physical dimensions: 0.633" L x 0.485" W (16.08mm x 12.32mm)
• Height - Seated (Max): 1.372" (34.85mm)
• Terminations: 2
• Moisture Sensitivity Level: 1 (Unlimited)

The primary distinction between these parts is the RoHS compliance status and the presence of REACH documentation availability on the substitute part.

Parameter Comparison

Engineering Selection Recommendations

Both the CPCP1020R00JB321 and CPCP1020R00JE31 are active production parts from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory compliance requirements:

• Select CPCP1020R00JB321 when RoHS non-compliant designs are acceptable or when legacy system compatibility is required.
• Select CPCP1020R00JE31 when RoHS3 compliance is mandated by design specifications or regulatory requirements. This part also offers higher current inventory availability at 885 units.

Both parts carry the same ECCN classification (EAR99) and HTSUS code (8533.21.0080), ensuring equivalent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable?

A: Yes. Both parts have identical resistance values (20 Ohms), tolerance (±5%), power rating (10W), temperature coefficient (±20ppm/°C), and operating temperature range (-65°C to 275°C). They are direct electrical equivalents.

Q: What is the difference between CPCP1020R00JB321 and CPCP1020R00JE31?

A: The primary difference is RoHS compliance status. CPCP1020R00JE31 is RoHS3 compliant, while CPCP1020R00JB321 is RoHS non-compliant. The substitute part also lists REACH documentation availability. Both parts are mechanically and electrically identical.

Q: Can I use CPCP1020R00JE31 as a direct replacement in existing designs using CPCP1020R00JB321?

A: Yes, provided your design does not specifically require RoHS non-compliant components. The physical footprint, electrical performance, and thermal characteristics are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical dimensions of 0.633" L x 0.485" W (16.08mm x 12.32mm) with a maximum seated height of 1.372" (34.85mm). PCB layout and mechanical clearances are equivalent.

Q: Which part should I specify for new designs?

A: Specify CPCP1020R00JE31 for new designs unless RoHS non-compliance is explicitly required. This part offers RoHS3 compliance, higher inventory availability, and REACH documentation support.
