Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC12JB16M0 is determined by the following critical parameters:

• Resistance Value: Must be 16 MOhms
• Power Rating: Must be 0.5W (1/2W)
• Package Type: Must be Axial
• Composition: Must be Carbon Composition
• Physical Dimensions: Must match 0.142" Dia × 0.374" L (3.60mm × 9.50mm)
• Features: Must include Non-Inductive and Pulse Withstanding characteristics
• Operating Temperature Range: Must support -55°C to 125°C

The RC12KB16M0 qualifies as a substitute component. While it features a wider tolerance specification (±10% versus ±5%), it maintains identical resistance value, power rating, package type, composition, physical dimensions, and operating temperature range. Both components are manufactured by Stackpole Electronics Inc within the RC series.

Parameter Comparison

Engineering Selection Recommendations

The RC12KB16M0 is the designated substitute for the obsolete RC12JB16M0. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing environments.

The primary distinction between these components is tolerance specification. The RC12JB16M0 provides ±5% tolerance, while the RC12KB16M0 provides ±10% tolerance. Selection between these specifications depends on circuit requirements for resistance accuracy. The RC12KB16M0 is currently in active production status, ensuring availability for new designs and ongoing component procurement.

Both components share identical electrical characteristics, physical dimensions, and thermal operating range, enabling direct substitution at the board level without modification to PCB layouts or mechanical assemblies.

Frequently Asked Questions (FAQ)

Q: Can RC12KB16M0 be used as a direct replacement for RC12JB16M0?

A: Yes. Both components are mechanically and electrically compatible. They share identical resistance value (16 MOhms), power rating (0.5W), package type (Axial), physical dimensions (0.142" Dia × 0.374" L), and operating temperature range (-55°C to 125°C). The tolerance difference (±10% versus ±5%) is the only specification variance.

Q: What is the tolerance difference between these parts?

A: RC12JB16M0 specifies ±5% tolerance, while RC12KB16M0 specifies ±10% tolerance. This means the RC12KB16M0 allows a wider range of actual resistance values around the 16 MOhms nominal specification. Circuit designs tolerant of ±10% variation can use RC12KB16M0 without performance impact.

Q: Are both parts RoHS compliant?

A: Yes. Both RC12JB16M0 and RC12KB16M0 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Why is RC12JB16M0 marked as obsolete?

A: RC12JB16M0 is no longer in active production. The RC12KB16M0 serves as the active production equivalent within the Stackpole RC series, providing the same core functionality with wider tolerance specification.

Q: Do these components require any PCB layout modifications?

A: No. Both components are identical in physical dimensions and package type (Axial). Existing PCB layouts designed for RC12JB16M0 accommodate RC12KB16M0 without modification.
