Key Parameters

Substitute Part Grouping Explanation

Substitution of the CF18JB750R is determined by the following critical parameters:

• Resistance Value: Must remain 750 Ohms
• Tolerance: Must remain ±5%
• Composition: Carbon Film construction required
• Package Type: Axial configuration required
• Operating Temperature Range: Must support -55°C to 155°C minimum
• Temperature Coefficient: Must match 0 / -400ppm/°C specification
• Regulatory Compliance: ROHS3 Compliant status required

The identified substitute CFM14JT750R maintains all critical electrical and mechanical parameters while offering increased power dissipation capability (0.25W vs. 0.125W) and alternative packaging format (Cut Tape vs. Bulk). This upgrade path accommodates applications requiring higher thermal performance without compromising core specifications.

Parameter Comparison

Engineering Selection Recommendations

Both CF18JB750R and CFM14JT750R are active production components from Stackpole Electronics Inc with full ROHS3 compliance and REACH unaffected status. Selection between these parts depends on application power dissipation requirements and procurement packaging preferences. The CF18JB750R is suitable for applications with power dissipation up to 0.125W, while the CFM14JT750R accommodates applications requiring up to 0.25W dissipation. Both parts maintain identical electrical specifications, temperature performance, and physical dimensions, ensuring direct functional compatibility in circuit designs. Packaging format differs between bulk supply (CF18JB750R) and cut tape format (CFM14JT750R), affecting procurement and assembly workflows.

Frequently Asked Questions (FAQ)

Q: Can CFM14JT750R replace CF18JB750R in all applications?

A: CFM14JT750R is electrically and mechanically compatible with CF18JB750R. The higher power rating (0.25W vs. 0.125W) provides additional thermal margin. Physical dimensions are identical, ensuring PCB footprint compatibility. Substitution is valid where power dissipation does not exceed the original design specification.

Q: What is the primary difference between these two parts?

A: The primary difference is power rating. CF18JB750R is rated for 0.125W dissipation, while CFM14JT750R is rated for 0.25W. Resistance, tolerance, temperature range, and composition remain identical. Packaging format also differs: CF18JB750R is supplied in bulk, CFM14JT750R in cut tape format.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.067" diameter by 0.130" length (1.70mm x 3.30mm). They are directly interchangeable from a PCB layout and assembly perspective.

Q: Do both parts meet the same compliance standards?

A: Yes. Both CF18JB750R and CFM14JT750R are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements.

Q: Which part should be selected for new designs?

A: Selection depends on application power dissipation. For designs dissipating less than 0.125W, either part is acceptable. For designs approaching or exceeding 0.125W dissipation, CFM14JT750R provides additional thermal headroom and is the preferred selection.
