Substitute Part Grouping Explanation

Substitution eligibility for the CF12JA200R is determined by strict equivalence across the following critical parameters:

• Resistance value: 200 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Composition: Carbon Film (exact match required)
• Package: Axial through-hole (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• Temperature coefficient: 0 / -400ppm/°C (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The CFM12JT200R qualifies as a direct substitute based on identical electrical specifications and compliance certifications. Physical dimensions vary within acceptable mechanical tolerances for axial resistor form factors, with the substitute featuring a smaller diameter (0.091" vs 0.106") and shorter length (0.256" vs 0.335"), both within standard axial resistor dimensional variation.

Parameter Comparison

Engineering Selection Recommendations

Both CF12JA200R and CFM12JT200R are active production components from Stackpole Electronics Inc with identical electrical specifications and full compliance certifications (ROHS3 Compliant, REACH Unaffected). Selection between these parts is based on mechanical fit requirements within the target application. The CFM12JT200R offers a more compact axial form factor with reduced diameter and length, suitable for space-constrained PCB layouts. The CF12JA200R maintains a larger profile, which may be preferred for applications requiring enhanced mechanical robustness or specific board layout constraints. Both parts satisfy equivalent functional requirements for 200 Ohm, 0.5W resistive applications across the full operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can CFM12JT200R be used as a direct replacement for CF12JA200R?

A: Yes. Both parts are electrically identical with matching resistance (200 Ohms), tolerance (±5%), power rating (0.5W), temperature coefficient (0 / -400ppm/°C), and operating range (-55°C to 155°C). Both are ROHS3 Compliant and REACH Unaffected. The primary difference is physical size; CFM12JT200R is more compact.

Q: What are the dimensional differences between these parts?

A: CF12JA200R measures 0.106" diameter × 0.335" length (2.70mm × 8.50mm). CFM12JT200R measures 0.091" diameter × 0.256" length (2.30mm × 6.50mm). Both are axial through-hole packages with 2 terminations.

Q: Are there any electrical performance differences?

A: No. Both parts share identical electrical specifications including resistance value, tolerance, power rating, temperature coefficient, and operating temperature range.

Q: Which part should be selected for new designs?

A: Selection depends on PCB layout requirements. CFM12JT200R is recommended for space-constrained applications due to its smaller footprint. CF12JA200R may be preferred where larger component size is acceptable or beneficial for mechanical stability.
