Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CFM14JT910R is determined by strict equivalence across the following critical parameters:

• Resistance value: 910 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Carbon Film (exact match required)
• Package: Axial through-hole (exact match required)
• Temperature coefficient: 0 / -400ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Compliance: RoHS3 Compliant, REACH Unaffected (exact match required)

The CF14JT910R qualifies as a direct substitute based on full alignment with all electrical and mechanical parameters. Physical dimensions vary within acceptable tolerances for axial package form factors.

Parameter Comparison

Engineering Selection Recommendations

Both CFM14JT910R and CF14JT910R maintain Active product status with identical electrical specifications and full regulatory compliance. Selection between these parts is based on physical space constraints within the application. The CFM14JT910R offers a more compact form factor (1.70mm diameter, 3.30mm length), while the CF14JT910R provides a larger package (2.30mm diameter, 6.00mm length). Both parts satisfy RoHS3 and REACH requirements for regulated applications. Inventory availability may influence procurement decisions, with CF14JT910R currently showing higher stock levels (12,059 units versus 5,537 units).

Frequently Asked Questions (FAQ)

Q: Can CF14JT910R be used as a direct replacement for CFM14JT910R?

A: Yes. Both parts share identical electrical specifications (910 Ohms ±5%, 0.25W, carbon film composition) and operate within the same temperature range (-55°C ~ 155°C). The primary difference is physical package size. Substitution is valid when board layout accommodates the larger axial dimensions of the CF14JT910R.

Q: What are the physical dimension differences between these parts?

A: CFM14JT910R measures 0.067" diameter × 0.130" length (1.70mm × 3.30mm). CF14JT910R measures 0.091" diameter × 0.236" length (2.30mm × 6.00mm). Both are axial through-hole packages suitable for standard PCB mounting.

Q: Are both parts RoHS3 compliant?

A: Yes. Both CFM14JT910R and CF14JT910R carry ROHS3 Compliant designation and REACH Unaffected status, meeting current regulatory requirements for electronic components.

Q: What determines substitution eligibility for this resistor?

A: Substitution requires exact matching of resistance value (910 Ohms), tolerance (±5%), power rating (0.25W), composition (carbon film), package type (axial), temperature coefficient (0 / -400ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance certifications (RoHS3, REACH). Physical dimensions may vary within axial package tolerances.

Q: Which part should be selected for space-constrained applications?

A: The CFM14JT910R is the appropriate choice for applications with limited board space due to its smaller axial dimensions (1.70mm × 3.30mm). The CF14JT910R is suitable for standard density layouts where the larger package (2.30mm × 6.00mm) does not present constraints.
