Substitute Part Grouping Explanation

Substitution of the RC14JB3M60 is based on the following critical parameters that must remain constant or compatible:

• Resistance value: 3.6 MOhms (exact match required)
• Power rating: 0.25W minimum (equal or greater acceptable)
• Package type: Axial through-hole configuration
• Composition: Carbon composition technology
• Operating temperature range: -55°C to 125°C minimum
• Physical dimensions: Compatible with 0.094" Dia x 0.248" L footprint
• Compliance: ROHS3 and REACH requirements

The RC14KB3M60 qualifies as a substitute based on matching all critical parameters. The tolerance specification differs (±10% versus ±5%), which represents a relaxation of the tolerance requirement. This substitution is valid where the circuit design permits the wider tolerance band.

Parameter Comparison

Engineering Selection Recommendations

The RC14KB3M60 is the manufacturer-recommended substitute for the obsolete RC14JB3M60. Both components are manufactured by Stackpole Electronics Inc and maintain identical electrical and mechanical specifications with the exception of tolerance classification.

The primary advantage of selecting RC14KB3M60 is product availability. The substitute part maintains active production status with current inventory, whereas the original part is obsolete. Both parts satisfy ROHS3 and REACH compliance requirements, ensuring regulatory compatibility in current manufacturing environments.

The tolerance difference (±10% versus ±5%) represents the only functional distinction. Circuit designs that accommodate ±10% tolerance variation can implement this substitute without modification. Designs requiring ±5% tolerance specification must evaluate whether the relaxed tolerance affects circuit performance or system-level requirements.

Frequently Asked Questions (FAQ)

Q: Can RC14KB3M60 be used as a direct replacement for RC14JB3M60?

A: Yes, provided the circuit design permits ±10% tolerance. The substitute maintains identical resistance value, power rating, package configuration, and operating temperature range. Physical dimensions and footprint compatibility are equivalent.

Q: What is the primary reason for substitution?

A: The RC14JB3M60 is classified as obsolete. The RC14KB3M60 is the active production equivalent from the same manufacturer, ensuring long-term availability and supply chain continuity.

Q: Does the tolerance difference affect circuit performance?

A: Tolerance impact depends on circuit design requirements. Applications where resistor value variation within ±10% is acceptable will experience no functional difference. Circuits requiring tighter tolerance control must evaluate whether the relaxed specification affects performance parameters.

Q: Are both parts compliant with current regulations?

A: Yes. Both RC14JB3M60 and RC14KB3M60 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Is the physical footprint identical?

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 existing PCB designs.

Q: What is the operating temperature range for both parts?

A: Both components operate across -55°C to 125°C, providing equivalent thermal performance for industrial and commercial applications.
