• Termination Style: Soft Termination feature maintained across all variants

Two substitute parts are identified within the 1812Y FlexiCap™ series, both manufactured by Knowles Syfer with identical core electrical and mechanical specifications except for voltage rating or packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

1812Y5000334KXT (Upgrade Substitute): This part is suitable for applications requiring higher voltage margin. The 500V rating provides increased safety factor in circuits originally specified for 200V operation. All other electrical and mechanical parameters remain identical to the main part. This substitute is appropriate when design requirements allow for elevated voltage ratings without circuit modification. Product status is Active with full ROHS3 compliance and MSL 1 rating.

1812Y2000334KXT (Parametric Equivalent): This part maintains identical electrical specifications and voltage rating to the main part (0.33 µF, 200V, X7R). The primary difference is packaging format (Tape & Reel versus bulk). This substitute is appropriate for high-volume manufacturing environments where tape & reel packaging is standard. Product status is Active with full ROHS3 compliance and MSL 1 rating.

Both substitutes are manufactured by Knowles Syfer within the same FlexiCap™ series and share identical compliance certifications (ROHS3, REACH Unaffected, EAR99, HTSUS 8532.24.0020).

Frequently Asked Questions (FAQ)

Q: Can 1812Y5000334KXT be used as a direct replacement for 1812Y2000334KDT?

A: Yes. The 1812Y5000334KXT is electrically and mechanically compatible. It maintains identical capacitance (0.33 µF), tolerance (±10%), temperature coefficient (X7R), package (1812), and operating temperature range (-55°C ~ 125°C). The 500V rating is a superset of the 200V requirement, making it suitable for any circuit designed for the original part.

Q: What is the difference between 1812Y2000334KDT and 1812Y2000334KXT?

A: These parts are parametrically identical in all electrical specifications. The primary difference is packaging format: 1812Y2000334KDT is supplied in bulk packaging, while 1812Y2000334KXT is supplied in Tape & Reel (TR) format. Selection depends on manufacturing process requirements and inventory management practices.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the same 1812 (4532 Metric) surface mount package with identical physical dimensions (4.50mm L x 3.20mm W x 2.50mm Max Thickness). They are mechanically interchangeable on PCB layouts.

Q: Do these substitutes require any circuit design changes?

A: No circuit design changes are required. All substitutes maintain the same capacitance value, tolerance, temperature coefficient, and operating temperature range. The 1812Y5000334KXT offers higher voltage rating, which is backward-compatible with 200V circuit specifications.

Q: What is the moisture sensitivity level for these parts?

A: All three parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling procedures apply without special moisture control requirements.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.
