RC14JB2M00 Equivalent & Substitute Parts

Part Overview

The RC14JB2M00 is a 2 MOhms ±5% 0.25W (1/4W) through-hole resistor with axial leads, manufactured by Stackpole Electronics Inc. This carbon composition resistor features non-inductive and pulse withstanding characteristics, designed for applications requiring precision resistance in compact form factors.

The RC14JB2M00 is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC14JB2M00 is determined by the following critical parameters:

• Resistance Value: Must be 2 MOhms
• Power Rating: Must be 0.25W (1/4W)
• Package Type: Must be Axial
• Composition: Must be Carbon Composition
• Operating Temperature Range: Must support -55°C ~ 125°C
• Physical Dimensions: Must match 0.094" Dia x 0.248" L (2.40mm x 6.30mm)
• Features: Must include Non-Inductive and Pulse Withstanding characteristics

The tolerance specification (±5% for the main part) may vary within acceptable engineering limits for substitute parts, provided the substitute maintains functional equivalence in the target application. Tolerance relaxation from ±5% to ±10% is permissible when circuit design margins accommodate the wider tolerance band.

Engineering Selection Recommendations

The RC14KB2M00 is the primary substitute for the obsolete RC14JB2M00. Both parts are manufactured by Stackpole Electronics Inc and share identical electrical specifications with the exception of tolerance rating.

Key Selection Factors:

• Product Status: The RC14KB2M00 maintains active product status, ensuring ongoing availability and supply chain reliability compared to the obsolete RC14JB2M00.
• Compliance: Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.
• Tolerance Consideration: The RC14KB2M00 specifies ±10% tolerance versus the ±5% tolerance of the RC14JB2M00. This tolerance difference is acceptable for applications where circuit design margins accommodate the wider tolerance band.
• Physical and Electrical Equivalence: Identical power rating, package type, operating temperature range, and mechanical dimensions ensure direct form-fit-function compatibility.

Frequently Asked Questions (FAQ)

Q: Can RC14KB2M00 directly replace RC14JB2M00 in all applications?

A: The RC14KB2M00 is electrically and mechanically equivalent to the RC14JB2M00 for applications tolerating ±10% resistance variation. Applications requiring ±5% tolerance precision must evaluate whether the wider tolerance of the substitute part meets circuit performance requirements.

Q: What is the primary difference between these two parts?

A: The tolerance specification differs. RC14JB2M00 is rated at ±5%, while RC14KB2M00 is rated at ±10%. All other electrical and mechanical parameters are identical.

Q: Are both parts available in the same packaging?

A: Yes. Both parts use identical axial package configuration with matching physical dimensions of 0.094" Dia x 0.248" L (2.40mm x 6.30mm), ensuring compatibility with existing PCB layouts and assembly processes.

Q: Do both parts meet current regulatory standards?

A: Yes. Both RC14JB2M00 and RC14KB2M00 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Why is RC14JB2M00 listed as obsolete?

A: The RC14JB2M00 has been discontinued by the manufacturer. The RC14KB2M00 remains in active production and serves as the recommended substitute for ongoing component procurement.
