Substitute Part Grouping Explanation

Substitute parts for the C274ACF4200SA0J are identified based on strict parametric equivalence within the KEMET C274 series. All substitute parts maintain identical electrical specifications: 2 µF capacitance, ±5% tolerance, 470V AC rating, and polypropylene metallized dielectric construction. All substitutes share the same radial can package configuration, chassis/stud mount capability, wire lead termination, and operating temperature range of -25°C to 85°C.

Substitution eligibility is determined by the following key parameters:

Capacitance value: 2 µF (exact match required)
Voltage rating: 470V AC (exact match required)
Dielectric type: Polypropylene (PP), Metallized (exact match required)
Package style: Radial, Can (exact match required)
Mounting configuration: Chassis, Stud Mount (exact match required)
Temperature range: -25°C to 85°C (exact match required)
RoHS3 compliance status (maintained across all parts)

Variations in physical dimensions (diameter and height) do not preclude substitution when all electrical and mounting parameters are identical, provided the application space accommodates the dimensional differences.

Engineering Selection Recommendations

All three parts—C274ACF4200SA0J, C274ACA4200AL0J, and C274ACF4200LF0J—are active KEMET products with full RoHS3 compliance and REACH unaffected status. Selection among these equivalents is based on availability, inventory levels, and physical space constraints within the application enclosure.

The C274ACA4200AL0J offers the smallest seated height at 2.244" (57.00mm), suitable for space-constrained applications. The C274ACF4200SA0J provides a mid-range height of 2.323" (59.00mm). The C274ACF4200LF0J presents the maximum seated height at 2.382" (60.50mm) and is appropriate for applications with adequate vertical clearance.

All parts maintain identical electrical performance, temperature stability, and regulatory compliance. Selection should prioritize inventory availability and dimensional compatibility with the target application's physical constraints.

Frequently Asked Questions (FAQ)

Q: Can C274ACA4200AL0J replace C274ACF4200SA0J in a motor run application?

A: Yes. Both parts are electrically identical 2 µF, 470V AC film capacitors with polypropylene metallized dielectric, ±5% tolerance, and identical operating temperature ranges. The primary difference is seated height: 2.244" versus 2.323". Substitution is valid provided the application accommodates the dimensional variation.

Q: What is the significance of the height difference between these substitute parts?

A: The three substitute parts have maximum seated heights of 57.00mm, 59.00mm, and 60.50mm respectively. These variations reflect different internal construction while maintaining identical electrical specifications. Height selection depends on available mounting space within the equipment enclosure.

Q: Are all three parts RoHS3 compliant?

A: Yes. C274ACF4200SA0J, C274ACA4200AL0J, and C274ACF4200LF0J are all RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Do these parts share the same package and mounting configuration?

A: Yes. All three parts use radial, can-style packaging with chassis and stud mount capability. Wire lead termination is identical across all parts, ensuring compatibility with existing PCB layouts and mounting hardware.

Q: Can these parts be used interchangeably in production?

A: Yes, provided the application's physical envelope accommodates the dimensional variations. All electrical parameters, temperature ratings, and compliance certifications are identical, supporting direct substitution in motor run applications.

Q: What is the operating temperature range for these capacitors?

A: All three parts operate across -25°C to 85°C, providing consistent thermal performance across the full substitute group.
