Key Parameters

Substitute Part Grouping Explanation

Substitution of the 37FD37175-F is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 17.5 µF
• Tolerance: ±10%
• Voltage rating (AC): 370V
• Dielectric material: Polypropylene (PP), Metallized

Mechanical Parameters:

• Package style: Radial, Can
• Mounting type: Chassis Mount, Requires Holder/Bracket
• Termination: Quick Connect, Disconnect
• Lead spacing: 0.813" (20.64mm)

Environmental & Compliance Parameters:

• Operating temperature range: -40°C ~ 70°C
• RoHS3 Compliance
• MSL rating: 1 (Unlimited)

Substitute parts must match all electrical parameters exactly and maintain mechanical compatibility within the specified dimensions and termination requirements. Physical dimensions may vary within acceptable tolerances provided the component fits the mounting bracket and maintains proper lead spacing.

Parameter Comparison

Engineering Selection Recommendations

The 37FD37175A-F is a direct electrical and mechanical equivalent to the 37FD37175-F. Both components are manufactured by Cornell Dubilier Electronics within the MPF series and share identical electrical specifications, dielectric composition, voltage rating, capacitance value, and tolerance.

Product Status Consideration: The 37FD37175-F is classified as obsolete, while the 37FD37175A-F maintains active product status. For new designs, repair applications, and ongoing production requirements, the 37FD37175A-F is the appropriate selection to ensure long-term component availability and supply chain continuity.

Compliance & Certification: Both parts are ROHS3 compliant and carry MSL rating 1 (Unlimited), meeting environmental and moisture sensitivity requirements for industrial applications.

Physical Dimension Variance: The 37FD37175A-F has a maximum seated height of 2.630" (66.80mm) compared to 2.880" (73.15mm) for the 37FD37175-F. This 0.250" (6.35mm) reduction in height does not affect electrical performance and may provide improved fit in space-constrained mounting configurations. Verification of bracket and holder clearance is necessary prior to installation.

Frequently Asked Questions (FAQ)

Q: Can the 37FD37175A-F be used as a direct replacement for the 37FD37175-F?

A: Yes. The 37FD37175A-F is electrically and mechanically equivalent. Both components share identical capacitance (17.5 µF), voltage rating (370V AC), tolerance (±10%), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 70°C), package style (radial can), and lead spacing (0.813"). The substitute part is manufactured by the same supplier (Cornell Dubilier Electronics) within the same MPF series.

Q: What is the primary difference between these two parts?

A: The primary difference is product status. The 37FD37175-F is obsolete, while the 37FD37175A-F is active. Additionally, the 37FD37175A-F has a reduced maximum seated height of 2.630" (66.80mm) versus 2.880" (73.15mm) for the original part. This dimensional change does not affect electrical performance.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, carry identical MSL ratings (1 - Unlimited), and share the same ECCN (EAR99) and HTSUS classifications.

Q: Does the height difference affect installation?

A: The 37FD37175A-F is 0.250" (6.35mm) shorter than the 37FD37175-F. Verify that the mounting bracket and holder provide adequate clearance for the substitute component. The shorter height may improve fit in space-constrained applications.

Q: What applications are these capacitors suitable for?

A: Both parts are rated for motor run and power factor correction (PFC) applications, operating at 370V AC with polypropylene metallized dielectric technology.

Q: Are there any temperature or environmental limitations?

A: Both components operate within the temperature range of -40°C to 70°C. MSL rating 1 (Unlimited) indicates no moisture sensitivity restrictions during storage or handling.
