Substitute Part Grouping Explanation

The CFM14JT910R qualifies as a substitute based on the following criteria:

Electrical Equivalence: Identical resistance value (910 Ohms) and tolerance (±5%) ensure functional compatibility in circuit applications.

Mechanical Compatibility: Both parts utilize axial package configuration with identical physical dimensions (0.067" Dia x 0.130" L / 1.70mm x 3.30mm), enabling direct board-level replacement without layout modifications.

Material & Composition: Both employ carbon film construction with flame retardant coating and safety features, maintaining equivalent environmental performance characteristics.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying identical regulatory requirements.

Temperature Performance: Identical temperature coefficient (0 / -400ppm/°C) and operating range (-55°C to 155°C) ensure equivalent thermal stability.

Key Differentiator: The CFM14JT910R provides increased power dissipation capability (0.25W / 1/4W versus 0.125W / 1/8W), allowing operation in higher power applications while maintaining all other specifications.

Parameter Comparison

Engineering Selection Recommendations

Both CF18JT910R and CFM14JT910R maintain Active product status with identical regulatory compliance profiles. Selection between these parts depends on circuit power dissipation requirements:

The CF18JT910R is appropriate for applications with power dissipation at or below 0.125W. The CFM14JT910R accommodates applications requiring power dissipation up to 0.25W while maintaining all electrical and mechanical specifications. Both parts satisfy ROHS3 and REACH compliance requirements for regulated markets.

Frequently Asked Questions (FAQ)

Q: Can CFM14JT910R replace CF18JT910R in any application? A: CFM14JT910R provides higher power rating (0.25W versus 0.125W) with identical electrical specifications and axial package dimensions. It functions as a direct replacement in all CF18JT910R applications. The higher power rating does not create incompatibility in lower-power circuits.

Q: Are the physical dimensions identical between these parts? A: Yes. Both CF18JT910R and CFM14JT910R share identical axial package dimensions of 0.067" Dia x 0.130" L (1.70mm x 3.30mm), enabling direct board-level substitution without PCB layout changes.

Q: Do both parts meet the same regulatory requirements? A: Both parts maintain ROHS3 compliance and REACH unaffected status. They satisfy identical regulatory requirements for restricted substance compliance and environmental regulations.

Q: What is the primary difference between these resistors? A: The CFM14JT910R provides 0.25W power rating compared to the CF18JT910R's 0.125W rating. All other specifications—resistance, tolerance, temperature coefficient, operating range, and package type—remain identical.

Q: Are there inventory considerations for substitution? A: Both parts maintain active inventory status. CF18JT910R has 5019 pieces in stock; CFM14JT910R has 5537 pieces in stock. Availability should not restrict substitution decisions based on technical requirements.
