Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1/2823KB are identified based on the following critical parameters that must remain constant or improve:

Matching Parameters (Required for Substitution):

• Resistance value: 82 kOhms
• Power rating: 0.5W (1/2W)
• Composition: Carbon Composition
• Package type: Axial
• Number of terminations: 2
• Physical form factor: Through-hole

Allowable Parameter Variations:

• Tolerance may be equal or tighter (±10% or better)
• Operating temperature range may be equal or extended
• Physical dimensions may vary within standard axial resistor tolerances
• Product status may transition from obsolete to active

The HWCC382 manufactured by NTE Electronics, Inc. meets all substitution criteria with improved tolerance specification (±5% versus ±10%) and extended operating temperature range (-55°C ~ 150°C versus -55°C ~ 125°C).

Parameter Comparison

Engineering Selection Recommendations

The HWCC382 is a direct functional substitute for the RC1/2823KB based on the following engineering criteria:

Electrical Equivalence: Both components provide identical 82 kOhms resistance at 0.5W power rating with carbon composition construction. The HWCC382 offers improved tolerance specification (±5%) which provides tighter resistance accuracy compared to the original ±10% specification.

Thermal Performance: The HWCC382 extends the operating temperature range to -55°C ~ 150°C, providing additional thermal margin beyond the RC1/2823KB specification of -55°C ~ 125°C.

Physical Compatibility: Axial package dimensions are within standard manufacturing tolerances, ensuring mechanical fit in existing PCB layouts designed for the RC1/2823KB.

Product Status and Compliance: The HWCC382 maintains active product status with ROHS3 compliance certification, supporting long-term supply chain continuity and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the HWCC382 be used as a direct replacement for the RC1/2823KB in existing circuits?

A: Yes. The HWCC382 provides identical electrical function with matching resistance value, power rating, and carbon composition construction. Physical dimensions are within standard axial resistor tolerances for PCB mounting compatibility.

Q: What is the significance of the tolerance difference between ±10% and ±5%?

A: The HWCC382 tolerance of ±5% provides tighter resistance accuracy. In circuits where the original ±10% tolerance was acceptable, the ±5% specification of the HWCC382 will also function correctly. The substitute will not introduce circuit incompatibility due to improved tolerance.

Q: Does the extended operating temperature range of the HWCC382 affect circuit performance?

A: The extended range (-55°C ~ 150°C versus -55°C ~ 125°C) provides additional thermal margin. If the original circuit operated within -55°C ~ 125°C, the HWCC382 will perform identically within that range and provide additional capability at higher temperatures.

Q: Are there any packaging differences between the RC1/2823KB and HWCC382?

A: Both components use axial through-hole packaging. The HWCC382 is supplied in bag packaging, while the original part number does not specify packaging format. Physical dimensions are within standard manufacturing tolerances for axial resistors.

Q: Is the HWCC382 RoHS compliant?

A: Yes. The HWCC382 is ROHS3 compliant, meeting current regulatory requirements for electronic component manufacturing and use.
