F1778322M2DBB0 Film Capacitor Equivalent & Substitute Parts

Part Overview

The F1778322M2DBB0 is a 0.022 µF film capacitor manufactured by Vishay Beyschlag/Draloric/BC Components, designed for EMI and RFI suppression applications. This radial polypropylene metallized capacitor operates at 630V DC and maintains active product status with 677 units currently in stock. Substitute parts become necessary when primary inventory is depleted, when lead times require alternative sourcing, or when design flexibility permits equivalent component selection within the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the F1778322M2DBB0 is based on strict electrical and mechanical parameter matching. The following criteria determine valid equivalency:

Electrical Parameters: Capacitance value (0.022 µF), tolerance (±20%), DC voltage rating (630V), AC voltage rating (310V), and dielectric material (Polypropylene, Metallized) must be identical.

Mechanical Parameters: Mounting type (Through Hole), package configuration (Radial), physical dimensions (0.492" L x 0.157" W), maximum seated height (0.394"), and lead spacing (0.394") must match exactly to ensure PCB compatibility.

Environmental & Compliance: Operating temperature range (-55°C to 110°C), X2 rating classification, and RoHS3 compliance status must be maintained.

The BFC233620223 meets all these criteria and qualifies as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the F1778322M2DBB0 and BFC233620223 maintain active product status and full ROHS3 compliance. Selection between these parts should be based on inventory availability and lead time requirements. The BFC233620223 (MKP336 2 series) currently has higher inventory availability at 4955 units compared to 677 units for the F1778322M2DBB0 (F1778X2 series). Both parts carry identical electrical specifications, mechanical dimensions, and environmental ratings, making them directly interchangeable at the component level. The choice between series variants does not affect circuit performance or PCB assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can the BFC233620223 be used as a direct replacement for the F1778322M2DBB0?

A: Yes. Both parts are parametric equivalents with identical capacitance (0.022 µF), voltage ratings (630V DC / 310V AC), tolerance (±20%), dielectric material (Polypropylene Metallized), physical dimensions, lead spacing, and operating temperature range. They are mechanically and electrically interchangeable.

Q: Are there any differences in the physical package between these two parts?

A: No. Both parts share identical dimensions (0.492" L x 0.157" W), maximum seated height (0.394"), lead spacing (0.394"), and radial through-hole configuration. PCB footprints are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the F1778322M2DBB0 and BFC233620223 are ROHS3 compliant, REACH unaffected, and carry X2 ratings. They meet identical regulatory requirements.

Q: What is the difference between the F1778X2 and MKP336 2 series designations?

A: These are internal series classifications from Vishay Beyschlag/Draloric/BC Components. The series designation does not affect electrical performance or mechanical compatibility. Both series meet the same specifications for this 0.022 µF 630V application.

Q: Which part should I select based on availability?

A: Selection should prioritize current inventory levels and procurement lead times. The BFC233620223 has higher stock availability (4955 units) compared to the F1778322M2DBB0 (677 units). Both parts are functionally equivalent for EMI and RFI suppression applications.
