Key Parameters

Substitute Part Grouping Explanation

Substitution for the FG18C0G1H080DNT06 is determined by strict equivalence in the following parameters: capacitance value (8 pF), tolerance (±0.5pF), temperature coefficient (C0G/NP0), mounting type (Through Hole), package style (Radial), and physical dimensions including lead spacing. The rated voltage may be upgraded to a higher value while maintaining all other specifications, as this provides enhanced reliability margins without affecting circuit performance in applications designed for 50V operation. The substitute part FG18C0G2A080DNT06 meets all these criteria with an upgraded voltage rating of 100V, identical physical footprint, and active product status from the same manufacturer.

Parameter Comparison

Engineering Selection Recommendations

The FG18C0G2A080DNT06 is the direct substitute for FG18C0G1H080DNT06. Both parts are manufactured by TDK Corporation and maintain identical electrical specifications for capacitance, tolerance, and temperature coefficient. The substitute part carries an upgraded voltage rating of 100V compared to the original 50V specification, with no change to physical dimensions or lead configuration. The substitute part holds Active product status, ensuring continued availability and supply chain support, whereas the original part is designated Not For New Designs. Both parts maintain ROHS3 compliance and REACH Unaffected status. The identical footprint and lead spacing enable direct board-level substitution without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can FG18C0G2A080DNT06 be used as a direct replacement for FG18C0G1H080DNT06?

A: Yes. Both parts share identical capacitance (8 pF), tolerance (±0.5pF), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), physical dimensions (4.00mm x 2.50mm), lead spacing (2.50mm), and mounting configuration (Through Hole Radial). The substitute part features a higher voltage rating (100V vs. 50V), which does not affect compatibility in circuits designed for 50V operation.

Q: Are there any PCB layout considerations when substituting these parts?

A: No. Both parts maintain identical physical dimensions, lead spacing, and radial package configuration. No PCB modifications are required for substitution.

Q: What is the significance of the voltage rating difference?

A: The substitute part's 100V rating provides a higher safety margin in the same physical package. This does not alter electrical performance in 50V-rated circuits and may improve long-term reliability under thermal stress.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both FG18C0G1H080DNT06 and FG18C0G2A080DNT06 are ROHS3 Compliant and REACH Unaffected.

Q: Why is the original part marked as Not For New Designs?

A: This designation indicates that TDK has superseded this part in their active product portfolio. The substitute part FG18C0G2A080DNT06 represents the current active equivalent with enhanced specifications.
