Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC1/2U106KB is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 10 MOhms (exact match required)
• Tolerance: ±10% (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Composition: Carbon Composition (exact match required)

Mechanical Parameters:

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

Environmental & Compliance Parameters:

• Operating temperature range: -55°C ~ 125°C (exact match required)
• RoHS compliance status (equivalent or higher compliance level acceptable)

The substitute part RC12KB10M0 meets all critical electrical, mechanical, and environmental parameters, establishing it as a direct parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Frequently Asked Questions (FAQ)

Q: Can RC12KB10M0 be used as a direct replacement for RC1/2U106KB in existing designs?

A: Yes. The RC12KB10M0 meets all critical electrical and mechanical parameters: identical 10 MOhms resistance, ±10% tolerance, 0.5W power rating, carbon composition construction, axial package type, and 3.60mm x 9.50mm dimensions. Both components operate across the same -55°C ~ 125°C temperature range and are RoHS compliant.

Q: Are there physical installation differences between these two parts?

A: No. Both the RC1/2U106KB and RC12KB10M0 share identical physical dimensions (0.142" Dia x 0.374" L / 3.60mm x 9.50mm) and axial lead configuration with 2 terminations. They are mechanically interchangeable in PCB layouts and through-hole applications.

Q: What is the significance of the "Non-Inductive, Pulse Withstanding" features listed for RC12KB10M0?

A: These features indicate design characteristics of the Stackpole Electronics part that enhance performance in specific applications. Non-inductive construction reduces parasitic inductance, and pulse withstanding capability provides robustness against transient voltage events. These features do not affect basic substitution compatibility but may provide performance advantages in sensitive circuits.

Q: Does the ROHS3 compliance of RC12KB10M0 differ from the RoHS Compliant status of RC1/2U106KB?

A: ROHS3 represents an updated compliance designation reflecting current regulatory standards. Both parts are RoHS compliant and suitable for applications requiring lead-free, restricted substance compliance. The ROHS3 designation indicates the Stackpole part meets current regulatory requirements.

Q: Are there any packaging or supply differences between these parts?

A: The RC1/2U106KB is available in standard packaging with 708 pieces in current inventory. The RC12KB10M0 is supplied in bulk packaging with 1,622 pieces available. Both are new original stock. Packaging format should be confirmed with your supplier based on production requirements.

Q: Can these parts be used interchangeably in both new designs and repair/replacement applications?

A: Yes. The parametric equivalence of RC12KB10M0 to RC1/2U106KB supports use in both new product designs and field replacement scenarios. The identical electrical and mechanical specifications ensure functional compatibility across all application contexts.
