Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC14JB910K is determined by the following critical parameters:

• Resistance Value: 910 kOhms (exact match required)
• Power Rating: 0.25W minimum (0.25W or higher acceptable)
• Package Type: Axial through-hole (mechanical and electrical compatibility)
• Composition: Carbon composition (electrical characteristics and environmental performance)
• Operating Temperature Range: -55°C to 125°C minimum (thermal compatibility)
• Compliance: ROHS3 and REACH requirements

The RC14KB910K qualifies as a substitute based on matching resistance value, power rating, package type, composition, operating temperature range, and compliance certifications. The tolerance difference (±10% versus ±5%) represents the primary electrical distinction and must be evaluated against circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The RC14KB910K is the manufacturer-recommended substitute for the obsolete RC14JB910K. Both parts are manufactured by Stackpole Electronics Inc and share identical mechanical dimensions, electrical composition, and compliance certifications (ROHS3 and REACH).

The primary distinction is tolerance specification: the RC14KB910K carries ±10% tolerance compared to the RC14JB910K's ±5% tolerance. This tolerance difference must be evaluated against circuit design requirements. Applications with strict tolerance requirements may require additional circuit compensation or selection screening.

The RC14KB910K maintains active product status, ensuring ongoing availability and supply chain continuity compared to the obsolete RC14JB910K.

Frequently Asked Questions (FAQ)

Q: Can the RC14KB910K directly replace the RC14JB910K in all applications?

A: Direct replacement is mechanically and thermally compatible. The tolerance difference (±10% versus ±5%) must be evaluated against circuit specifications. Applications requiring ±5% tolerance precision may require circuit redesign or tolerance screening.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts measure 0.094" diameter by 0.248" length (2.40mm x 6.30mm), ensuring identical PCB footprint and mounting compatibility.

Q: Do both parts meet current compliance requirements?

A: Yes. Both RC14JB910K and RC14KB910K are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Why is the RC14JB910K obsolete?

A: The RC14JB910K is listed as obsolete. The RC14KB910K represents the active product line continuation from Stackpole Electronics Inc for this resistance value and package type.

Q: Are there inventory considerations for selection?

A: The RC14KB910K is currently in active production with 642 pieces in stock. The RC14JB910K, being obsolete, has limited remaining inventory (991 pieces noted as new original stock).
