RC14JB5M10 Equivalent & Substitute Parts

Part Overview

The RC14JB5M10 is a 5.1 MOhm ±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 values in compact form factors.

The RC14JB5M10 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production, repair, and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC14JB5M10 is determined by the following critical parameters:

• Resistance value: 5.1 MOhms (exact match required)
• Power rating: 0.25W (1/4W) minimum
• Package type: Axial configuration
• Composition: Carbon composition
• Operating temperature range: -55°C ~ 125°C minimum
• Compliance certifications: ROHS3 Compliant

The RC14KB5M10 qualifies as a substitute based on matching all critical electrical and mechanical parameters. The tolerance difference (±10% versus ±5%) represents a relaxation of precision requirements and is acceptable in applications where the original ±5% tolerance is not a functional constraint.

Parameter Comparison

Engineering Selection Recommendations

The RC14KB5M10 is the primary substitute for the obsolete RC14JB5M10. Both parts are manufactured by Stackpole Electronics Inc and maintain identical electrical performance characteristics across resistance value, power rating, and operating temperature range.

The RC14KB5M10 carries active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing and deployment.

The tolerance specification difference (±10% versus ±5%) should be evaluated against circuit design requirements. Applications with strict tolerance requirements may require circuit redesign or alternative component selection strategies.

Frequently Asked Questions (FAQ)

Q: Can the RC14KB5M10 directly replace the RC14JB5M10 in all applications?

A: Direct replacement is possible when circuit design tolerates ±10% resistance variation. Applications requiring ±5% tolerance precision require design review or alternative component sourcing.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical axial package dimensions of 0.094" diameter by 0.248" length (2.40mm x 6.30mm), ensuring mechanical compatibility in PCB layouts and through-hole designs.

Q: What is the significance of the product status difference?

A: The RC14JB5M10 is obsolete and no longer manufactured. The RC14KB5M10 maintains active status, guaranteeing continued availability from Stackpole Electronics Inc and authorized distributors.

Q: Do both parts meet current regulatory compliance standards?

A: Yes. Both the RC14JB5M10 and RC14KB5M10 are ROHS3 compliant and REACH unaffected, satisfying current environmental and regulatory requirements for electronic component manufacturing and deployment.

Q: Are there any differences in operating temperature performance?

A: No. Both parts operate across the identical temperature range of -55°C to 125°C, ensuring equivalent thermal performance in specified operating environments.
