Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC1/2102KB is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 1 kOhms
• Tolerance: ±10%
• Power rating: 0.5W (1/2W)
• Composition: Carbon Composition

Mechanical Parameters:

• Package type: Axial
• Physical dimensions: 0.142" Dia x 0.374" L (3.60mm x 9.50mm)
• Number of terminations: 2

Environmental Parameters:

• Operating temperature range: -55°C ~ 125°C
• Moisture sensitivity: Not Applicable

The substitute part RC12KB1K00 manufactured by Stackpole Electronics Inc. meets all specified electrical and mechanical parameters. Additional features present in the substitute (non-inductive design, pulse withstanding capability) do not conflict with the original specification and provide enhanced performance characteristics within the same form factor and electrical rating.

Parameter Comparison

Engineering Selection Recommendations

The RC12KB1K00 manufactured by Stackpole Electronics Inc. is a direct parametric equivalent to the RC1/2102KB. Both components share identical electrical specifications (1 kOhms ±10% at 0.5W), mechanical form factor (axial package, 3.60mm x 9.50mm), and operating temperature range (-55°C ~ 125°C).

The substitute part carries ROHS3 compliance and REACH unaffected status, providing regulatory alignment for modern applications. Both parts are classified as obsolete, reflecting their legacy status in the component market.

Selection of the RC12KB1K00 as a substitute is supported by complete parametric alignment and identical packaging specifications, ensuring direct form-fit-function compatibility in circuit board layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can RC12KB1K00 be used as a direct replacement for RC1/2102KB?

A: Yes. The RC12KB1K00 meets all electrical and mechanical specifications of the RC1/2102KB, including resistance value, tolerance, power rating, package type, and physical dimensions. Both components are carbon composition axial resistors with identical operating temperature ranges.

Q: Are there physical dimension differences between these parts?

A: No. Both the RC1/2102KB and RC12KB1K00 share identical physical dimensions of 0.142" diameter by 0.374" length (3.60mm x 9.50mm), ensuring compatibility with existing printed circuit board layouts and assembly equipment.

Q: What is the significance of the "non-inductive" and "pulse withstanding" features in the RC12KB1K00?

A: These features represent enhanced performance characteristics of the Stackpole Electronics part.
