Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CF14JB100R is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance Value: 100 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power Rating: 0.25W / 1/4W (exact match required)
• Package Type: Axial Through-Hole (exact match required)
• Composition: Carbon Film (exact match required)
• Operating Temperature Range: -55°C to +155°C (minimum requirement)
• Termination Count: 2 (exact match required)
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The substitute part CFR-25JB-52-100R manufactured by YAGEO meets all mandatory matching parameters and qualifies as a direct electrical and mechanical equivalent.

Parameter Comparison

Engineering Selection Recommendations

The CFR-25JB-52-100R manufactured by YAGEO qualifies as a direct substitute for the CF14JB100R based on electrical and mechanical equivalence across all mandatory parameters. Both parts are Active products with ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for current and future applications.

Physical dimensions show minor variations (0.091" vs 0.094" diameter; 0.236" vs 0.248" length), which remain within acceptable tolerances for standard through-hole PCB layouts and do not impact functional performance or mechanical fit in typical circuit board designs.

Temperature coefficient specifications differ between the two parts (Stackpole: 0 / -400 ppm/°C; YAGEO: -500 / +350 ppm/°C). Both operate across the identical temperature range of -55°C to +155°C. Selection between these parts should consider application-specific temperature stability requirements if precision resistance tracking across temperature extremes is critical.

Both parts carry identical electrical specifications: 100 Ohms ±5% at 0.25W power rating with carbon film composition. Substitution is electrically transparent for general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can CFR-25JB-52-100R replace CF14JB100R in existing designs without PCB modification?

A: Yes. Both parts are axial through-hole resistors with 2 terminations and compatible lead spacing for standard 0.1" pitch PCB layouts. Minor physical dimension differences (approximately 0.003" diameter and 0.012" length variations) do not require PCB redesign.

Q: Are there electrical performance differences between these two parts?

A: Both parts deliver identical electrical performance: 100 Ohms ±5% at 0.25W across -55°C to +155°C. Temperature coefficient specifications differ, but both parts meet the operating temperature range requirement. Applications requiring tight temperature coefficient control should verify specific performance needs.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both CF14JB100R and CFR-25JB-52-100R are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: What is the primary reason to use a substitute part?

A: Substitute parts provide alternative sourcing when the primary part (CF14JB100R) experiences supply constraints, extended lead times, or inventory depletion. Both parts maintain Active product status and equivalent specifications.

Q: Are there inventory considerations for these parts?

A: CF14JB100R currently has 1114 units in stock. CFR-25JB-52-100R has 9085 units available. Substitute selection may be driven by inventory availability and supply chain optimization requirements.

Q: Can these parts be used interchangeably in high-precision applications?

A: Both parts meet the ±5% tolerance specification and operate across -55°C to +155°C. Applications requiring precision beyond ±5% tolerance or specialized temperature coefficient performance should evaluate specific application requirements against the provided temperature coefficient data.
