Frequently Asked Questions (FAQ)

Q: Can 1111J5002P40CQT be used as a direct replacement for 1111J5002P40CUT?

A: Yes. Both parts are manufactured by Knowles Syfer with identical capacitance (2.4 pF), tolerance (±0.25pF), voltage rating (500V), temperature coefficient (C0G/NP0), and package dimensions (1111/2828 Metric). Electrical and mechanical compatibility is complete.

Q: Are there differences in the temperature coefficient designation?

A: The main part specifies C0G, NP0 (1B), while the substitute specifies C0G, NP0. Both designations represent the same temperature coefficient class with equivalent performance characteristics across the -55°C to 125°C operating range.

Q: What is the significance of the product status change from Obsolete to Active?

A: The substitute part's active status ensures ongoing availability, manufacturing support, and compliance with current regulatory standards. This eliminates supply chain risk associated with obsolete components.

Q: Are there any compliance differences between the two parts?

A: The substitute part includes ROHS3 compliance and REACH unaffected certification. Both parts carry the same ECCN (EAR99) and HTSUS (8532.24.0020) classifications.

Q: Will the substitute part fit existing PCB designs?

A: Yes. The 1111J5002P40CQT maintains identical package type (1111/2828 Metric), footprint dimensions (0.110" x 0.110"), and maximum thickness (0.070"), ensuring compatibility with existing surface mount assembly processes and PCB layouts.
