Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CM05FD151FO3 is strictly determined by the following key parameters: capacitance value (150 pF), tolerance (±1%), rated voltage (500 V), dielectric material (mica), operating temperature range (-55°C to 125°C), mounting type (through hole), and mechanical dimensions (lead spacing, package outline, and seated height). All substitute parts listed maintain identical electrical characteristics and physical specifications for direct board-level replacement without modification to circuit design or PCB layout.

The CM05FD151FO3 may be substituted with equivalent part numbers from the CD15 series, which share the same parametric values across all critical selection criteria.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers (CM05FD151FO3, CD15FD151FO3, and CD15FD151FO3F) are equivalent substitutes at the parametric level and maintain identical electrical and mechanical specifications. The primary differentiation factor is regulatory compliance status.

The CD15FD151FO3F is ROHS3 compliant and REACH unaffected, making it the preferred selection for applications subject to these regulatory requirements. The CM05FD151FO3 and CD15FD151FO3 remain RoHS non-compliant and REACH affected, respectively, and are suitable for applications without these compliance mandates.

Product status across all three parts is active with consistent availability, ensuring procurement reliability for board-level substitution.

Frequently Asked Questions (FAQ)

Q: Can the CM05FD151FO3 be directly replaced with the CD15FD151FO3 on a PCB?

A: Yes. Both parts are mechanically and electrically identical. They share the same lead spacing (0.232"), package outline dimensions (0.461" L x 0.189" W), and seated height (0.370"), enabling direct board-level substitution without PCB layout modification.

Q: What is the difference between CD15FD151FO3 and CD15FD151FO3F?

A: The parts are parametrically equivalent with identical electrical and mechanical specifications. The CD15FD151FO3F is ROHS3 compliant and REACH unaffected, while the CD15FD151FO3 is RoHS non-compliant and REACH affected. Selection depends on regulatory requirements applicable to your application or market region.

Q: Are all three parts from the same manufacturer?

A: Yes. All parts are manufactured by Cornell Dubilier Electronics (CDE). The CM05 series and CD15 series are both CDE product lines sharing the same parametric specifications for this capacitance, voltage, and tolerance combination.

Q: What does REACH affected status mean?

A: REACH affected indicates the part may contain substances regulated under the REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) directive. Regulatory compliance verification is necessary for applications subject to REACH requirements.

Q: Can I use these capacitors in high-temperature environments?

A: Yes. All three part numbers are rated for continuous operation across the -55°C to 125°C temperature range, making them suitable for high-temperature applications within the specified limits.

Q: What inventory levels are available for each part?

A: Current inventory includes 1019 pieces of CM05FD151FO3, 1027 pieces of CD15FD151FO3, and 947 pieces of CD15FD151FO3F, all listed as new original stock.
