CF14JT2R20 Equivalent & Substitute Parts

Part Overview

The CF14JT2R20 is a 2.2 Ohms ±5% 0.25W (1/4W) through-hole axial resistor manufactured by Stackpole Electronics Inc. This carbon film resistor features flame retardant coating and safety characteristics, designed for general-purpose electronic applications requiring precise resistance values with standard tolerance specifications. The part maintains active product status with ROHS3 compliance and REACH unaffected certification. Substitute parts are identified to address packaging format availability, power rating requirements, or inventory considerations while maintaining electrical and mechanical compatibility within specified parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CF14JT2R20 are qualified based on the following electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Resistance value: 2.2 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Composition: Carbon Film (exact match required)
• Temperature Coefficient: ±400ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match required)

Mechanical Compatibility Criteria:

• Package Type: Axial (exact match required)
• Number of Terminations: 2 (exact match required)

Allowable Variation:

• Power Rating: Substitutes may have equal or higher power ratings (0.25W or greater)
• Packaging Format: Substitutes may differ in tape format (Tape & Reel vs. Cut Tape)
• Physical Dimensions: Minor variations permitted when power rating increases

The CF14JT2R20 series includes two qualified substitutes: CFM12JT2R20 (upgraded power rating) and CFM14JT2R20 (manufacturer recommended equivalent with different physical dimensions).

Parameter Comparison

Engineering Selection Recommendations

CFM14JT2R20 (Manufacturer Recommended): This part is the manufacturer-recommended equivalent to CF14JT2R20. It maintains identical electrical specifications and power rating while offering Cut Tape packaging format. Both parts carry active product status with full ROHS3 and REACH compliance. Selection of CFM14JT2R20 is appropriate when Cut Tape packaging is preferred or when Tape & Reel format is unavailable.

CFM12JT2R20 (Upgrade Option): This substitute provides a higher power rating of 0.5W (1/2W) while maintaining all other electrical parameters. The increased power rating allows operation in applications with higher thermal stress or power dissipation requirements. This part is suitable for designs where the original 0.25W specification may be marginal or where design margin improvement is desired. Both parts maintain active status and full compliance certifications.

All three parts are manufactured by Stackpole Electronics Inc and carry identical compliance certifications, ensuring regulatory and quality consistency across substitution options.

Frequently Asked Questions (FAQ)

Q: Can CFM12JT2R20 be used as a direct replacement for CF14JT2R20?

A: Yes. CFM12JT2R20 maintains identical resistance (2.2 Ohms), tolerance (±5%), composition (Carbon Film), temperature coefficient (±400ppm/°C), and operating temperature range (-55°C to 155°C). The higher power rating (0.5W vs. 0.25W) provides additional thermal capability without affecting electrical performance in circuits designed for 0.25W operation.

Q: What is the difference between CF14JT2R20 and CFM14JT2R20?

A: Both parts are electrically identical 2.2 Ohms ±5% 0.25W carbon film resistors. The primary differences are packaging format (Tape & Reel vs. Cut Tape) and physical dimensions. CFM14JT2R20 is the manufacturer-recommended equivalent with smaller physical dimensions (0.067" Dia x 0.130" L vs. 0.091" Dia x 0.236" L).

Q: Are there any compatibility issues when substituting these parts?

A: No compatibility issues exist when substituting within this group. All parts share identical axial package type, two-terminal configuration, and electrical specifications. Physical dimension differences do not affect circuit functionality but may impact PCB layout considerations.

Q: Which substitute should be selected for new designs?

A: Selection depends on application requirements. For standard 0.25W applications, CFM14JT2R20 is the manufacturer-recommended choice. For applications requiring additional thermal margin or higher power dissipation capability, CFM12JT2R20 provides 0.5W rating while maintaining all other specifications.

Q: Do all parts meet the same compliance standards?

A: Yes. CF14JT2R20, CFM12JT2R20, and CFM14JT2R20 all carry ROHS3 compliance and REACH unaffected certification, ensuring equivalent regulatory status across all substitution options.
