Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CF14JB1K00 are identified based on strict electrical and mechanical parameter matching. The substitution logic requires:

Critical Matching Parameters:

• Resistance value: 1 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 0.25W / 1/4W (equal or greater capacity acceptable)
• Composition: Carbon Film (same technology class)
• Package: Axial (identical mechanical form factor)
• Operating temperature range: -55°C ~ 155°C (minimum requirement)

Compliance Parameters:

• RoHS3 compliance status
• REACH compliance status
• ECCN and HTSUS classifications

The CFR-25JB-52-1K from YAGEO meets all critical electrical parameters and compliance requirements, establishing it as a valid functional equivalent. Both parts share identical resistance, tolerance, power rating, composition, and package type. Operating temperature ranges are identical. Both parts maintain ROHS3 and REACH compliance status.

Engineering Selection Recommendations

Primary Part: CF14JB1K00 (Stackpole Electronics Inc)

Use the CF14JB1K00 as the first-choice component when available. This part is currently active in production with adequate inventory (626 pieces in stock). It maintains full ROHS3 and REACH compliance. The flame retardant coating and safety features provide additional protection characteristics suitable for applications requiring enhanced reliability.

Substitute Part: CFR-25JB-52-1K (YAGEO)

The CFR-25JB-52-1K is a valid functional equivalent for the CF14JB1K00. Both parts satisfy identical electrical specifications: 1 kOhms resistance, ±5% tolerance, 0.25W power rating, carbon film composition, and axial package configuration. Both maintain -55°C ~ 155°C operating temperature range and ROHS3/REACH compliance. The CFR-25JB-52-1K offers significantly higher inventory availability (103,876 pieces in stock), supporting supply chain flexibility and procurement continuity.

Selection Criteria:

• Select CF14JB1K00 when flame retardant coating and safety features are specified design requirements
• Select CFR-25JB-52-1K when supply availability is the primary consideration and flame retardant coating is not required
• Both parts are suitable for identical circuit applications requiring 1 kOhms ±5% 0.25W fixed resistance
• Physical dimension variations (0.091" vs 0.094" diameter; 0.236" vs 0.248" length) are minor and do not affect standard PCB footprint compatibility for axial resistor layouts
• Temperature coefficient differences do not affect substitution validity for general-purpose applications; verify temperature coefficient specifications if circuit design includes precision temperature compensation requirements

Frequently Asked Questions (FAQ)

Q: Can CFR-25JB-52-1K replace CF14JB1K00 in any application?

A: Yes, for applications where the primary design requirement is 1 kOhms ±5% 0.25W fixed resistance in axial package format. Both parts meet identical electrical specifications and compliance requirements. If the design specifically requires flame retardant coating or the safety features of the CF14JB1K00, verify that the CFR-25JB-52-1K meets those additional requirements before substitution.

Q: What is the difference in physical dimensions between these parts?

A: CF14JB1K00 measures 0.091" diameter x 0.236" length (2.30mm x 6.00mm). CFR-25JB-52-1K measures 0.094" diameter x 0.248" length (2.40mm x 6.30mm). These minor variations do not affect standard axial resistor PCB footprint compatibility or lead spacing.

Q: Are both parts RoHS compliant?

A: Yes. Both CF14JB1K00 and CFR-25JB-52-1K are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the temperature coefficient difference, and does it matter?

A: CF14JB1K00 specifies 0 / -400 ppm/°C; CFR-25JB-52-1K specifies -500 / +350 ppm/°C. Temperature coefficient defines resistance value drift across temperature ranges. For general-purpose applications, this difference is not significant. For precision circuits requiring tight temperature stability, verify that the CFR-25JB-52-1K temperature coefficient meets circuit design specifications before substitution.

Q: Which part should I select for new designs?

A: For new designs, either part is acceptable based on availability and specific design requirements. If flame retardant coating is a design specification, use CF14JB1K00. If supply availability and cost are primary considerations, CFR-25JB-52-1K is suitable. Both parts are active in production and maintain full compliance status.

Q: Can these parts be used interchangeably on existing PCBs?

A: Yes. Both parts use identical axial package configuration with 2 terminations and standard lead spacing. Minor physical dimension variations do not affect PCB assembly compatibility. Existing PCB designs for CF14JB1K00 can accommodate CFR-25JB-52-1K without layout modifications.
