• Voltage Rating (AC): 370V
• Dielectric Material: Polypropylene (PP), Metallized

Mechanical Parameters (Non-Negotiable):

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

Environmental Parameters:

• Operating Temperature Range: -40°C ~ 70°C
• RoHS3 Compliance
• Moisture Sensitivity Level (MSL): 1

The substitute part 37FD3715A-F meets all electrical, mechanical, and environmental criteria for direct substitution. Physical dimension variations within the can assembly do not affect functional compatibility when mounting hardware and holder/bracket specifications are maintained.

Parameter Comparison

Engineering Selection Recommendations

The 37FD3715A-F is a direct functional equivalent to the 37FD3715-F for all motor run and power factor correction applications. Selection between these parts is based on availability and product lifecycle status:

37FD3715-F Selection Criteria:

• Current inventory: 1,139 pieces available
• Product Status: Obsolete
• Use when existing stock must be maintained or when legacy system documentation specifies this exact part number

37FD3715A-F Selection Criteria:

• Current inventory: 859 pieces available
• Product Status: Active
• Recommended for new designs, system upgrades, and long-term supply chain planning
• Provides continued manufacturer support and availability assurance
• Reduced seated height (66.80mm vs. 73.15mm) may provide installation advantages in space-constrained applications

Both parts carry identical electrical ratings, mechanical specifications, and compliance certifications (ROHS3, MSL 1). The height difference of 0.250" (6.35mm) is accommodated within standard chassis mount holder/bracket tolerances and does not affect electrical performance or functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can 37FD3715A-F replace 37FD3715-F in existing equipment?

A: Yes. The 37FD3715A-F is electrically and mechanically equivalent. Both parts share identical capacitance (15 µF), voltage rating (370V AC), tolerance (±10%), dielectric material (polypropylene metallized), package type (radial can), lead spacing (0.813"), and operating temperature range (-40°C to 70°C). The seated height difference (6.35mm) is within standard chassis mount holder/bracket accommodation.

Q: What is the significance of the product status difference?

A: The 37FD3715-F is classified as obsolete, indicating discontinued manufacturing. The 37FD3715A-F is active, meaning it remains in current production with ongoing manufacturer support. For applications requiring long-term component availability and supply chain stability, the active part is preferred.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant and carry identical MSL (Moisture Sensitivity Level) ratings of 1 (unlimited). Both are classified under ECCN EAR99 and HTSUS 8532.25.0020.

Q: Does the height difference affect installation?

A: No. The 37FD3715A-F has a maximum seated height of 2.630" (66.80mm) compared to 2.880" (73.15mm) for the 37FD3715-F. This 0.250" reduction is accommodated within standard chassis mount holder/bracket specifications and does not compromise mechanical fit or electrical performance.

Q: What applications are these capacitors suitable for?

A: Both parts are rated for motor run and power factor correction (PFC) applications. The 370V AC rating and polypropylene metallized construction support these industrial and commercial uses.

Q: Is the quick connect termination compatible between both parts?

A: Yes. Both parts feature identical quick connect/disconnect termination, ensuring compatibility with existing connection hardware and installation procedures.
