Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CF18JA220R is determined by the following critical parameters:

• Resistance Value: Must be 220 Ohms
• Tolerance: Must be ±5% or tighter
• Composition: Carbon film construction
• Package Type: Axial through-hole configuration
• Temperature Coefficient: 0 / -400ppm/°C or equivalent
• Operating Temperature Range: -55°C to 155°C minimum
• RoHS Compliance: ROHS3 Compliant

The CFM14JA220R qualifies as a substitute part. While it features a higher power rating (0.25W / 1/4W versus 0.125W / 1/8W), all other electrical and mechanical parameters remain identical. The increased power dissipation capability provides functional equivalence for applications where the CF18JA220R is specified, as the higher power rating does not compromise performance in circuits designed for the lower-rated component.

Parameter Comparison

Engineering Selection Recommendations

Both the CF18JA220R and CFM14JA220R are active production components manufactured by Stackpole Electronics Inc and maintain full ROHS3 compliance and REACH unaffected status. The CFM14JA220R substitute part provides identical electrical performance with enhanced power dissipation capability. Selection between these parts should be based on circuit power requirements and PCB thermal management considerations. The higher inventory availability of the CFM14JA220R (5160 units versus 1734 units) may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can the CFM14JA220R replace the CF18JA220R in all applications?

A: Yes. The CFM14JA220R provides equivalent electrical performance with a higher power rating. The increased power dissipation capability (0.25W versus 0.125W) does not create incompatibility in circuits designed for the CF18JA220R.

Q: Are there physical dimension differences between these parts?

A: No. Both parts share identical axial package dimensions: 0.067" diameter × 0.130" length (1.70mm × 3.30mm).

Q: Do both parts meet the same compliance standards?

A: Yes. Both the CF18JA220R and CFM14JA220R are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements.

Q: What is the temperature coefficient difference?

A: Both parts feature identical temperature coefficient specifications of 0 / -400ppm/°C and operate across the same temperature range of -55°C to 155°C.

Q: Are there series differences between CF and CFM designations?

A: The CF18JA220R belongs to the CF series, while the CFM14JA220R belongs to the CFM series. The primary distinction is the power rating: CF series at 1/8W and CFM series at 1/4W. Both series maintain identical tolerance, composition, and thermal characteristics.
