Substitute Part Grouping Explanation

The substitute part CDV19EF270JO3F qualifies as a direct equivalent based on the following criteria:

Electrical Parameters: Both parts maintain identical capacitance (27 pF), tolerance (±5%), and voltage rating (1 kV), ensuring functional equivalence in circuit applications.

Mechanical Parameters: Lead spacing (0.343"/8.70mm), physical dimensions (0.642" L x 0.189" W), and maximum seated height (0.500") are identical, confirming PCB footprint compatibility and mechanical fit.

Environmental Parameters: Operating temperature range (-55°C ~ 125°C) and dielectric material (Mica) are unchanged, preserving performance characteristics across the specified temperature spectrum.

Manufacturing Parameters: Both parts use Through Hole mounting with Radial packaging, maintaining assembly process compatibility.

Key Differentiator: The primary distinction is RoHS and REACH compliance status, with CDV19EF270JO3F offering enhanced regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring RoHS3 compliance: Select CDV19EF270JO3F. This variant meets current environmental and hazardous substance restrictions, making it suitable for products distributed in regulated markets.

For applications where REACH compliance is necessary: CDV19EF270JO3F is the appropriate choice, as it is classified as REACH Unaffected, eliminating compliance burden in supply chain documentation.

For legacy systems or non-regulated applications: CDV19EF270JO3 remains functional and electrically equivalent, with higher availability of 678 units versus 1067 units for the compliant variant.

Both parts maintain identical electrical and mechanical specifications, ensuring direct interchangeability in circuit design without performance degradation.

Frequently Asked Questions (FAQ)

Q: Can CDV19EF270JO3F replace CDV19EF270JO3 in existing designs? A: Yes. The substitute part is electrically and mechanically identical, with identical lead spacing and PCB footprint. The primary difference is enhanced RoHS3 and REACH compliance status.

Q: What determines whether these parts are substitutable? A: Substitution is valid when capacitance (27 pF), tolerance (±5%), voltage rating (1 kV), operating temperature range (-55°C ~ 125°C), lead spacing (0.343"/8.70mm), and package type (Radial Through Hole) are identical.

Q: Are there any mechanical constraints when switching between CDV19EF270JO3 and CDV19EF270JO3F? A: No. Both parts share identical physical dimensions (0.642" L x 0.189" W), maximum seated height (0.500"), and lead spacing (0.343"), ensuring interchangeable board placement.

Q: Which part should be selected for new designs? A: CDV19EF270JO3F is recommended for new designs due to RoHS3 compliance and REACH Unaffected status, providing regulatory alignment with current international standards.

Q: Is inventory level a factor in substitution decisions? A: Inventory levels do not affect electrical or mechanical compatibility. Component selection should prioritize compliance requirements and design specifications.
