Substitute Part Grouping Explanation

The 38FD37275A-F is classified as a direct equivalent substitute for the 38FD37275-F based on the following substitution criteria:

Electrical Parameters (Identical):

• Capacitance: 27.5 µF
• Voltage Rating (AC): 370V
• Tolerance: ±10%
• Dielectric Material: Polypropylene (PP), Metallized
• Operating Temperature Range: -40°C ~ 70°C

Mechanical Parameters (Compatible):

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

Regulatory & Compliance (Equivalent):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• ECCN: EAR99
• HTSUS: 8532.25.0020

The primary distinction between these parts is product status: 38FD37275-F is obsolete, while 38FD37275A-F is active production. The substitute maintains full electrical and mechanical compatibility for direct replacement in existing applications.

Engineering Selection Recommendations

Primary Recommendation: 38FD37275A-F

The 38FD37275A-F is the direct active production equivalent for the obsolete 38FD37275-F. Selection of this substitute is based on:

1. Electrical Equivalence: All electrical parameters (capacitance, voltage rating, tolerance, dielectric material, and operating temperature range) are identical to the original part.

2. Mechanical Compatibility: Physical dimensions, lead spacing, mounting type, and termination method are identical, ensuring direct replacement without modification to existing hardware or PCB layouts.

3. Product Status: The substitute is classified as active production, ensuring long-term availability and supply chain continuity compared to the obsolete original part.

4. Regulatory Compliance: Both parts maintain ROHS3 compliance and identical regulatory classifications (ECCN: EAR99; HTSUS: 8532.25.0020), satisfying environmental and trade requirements.

5. Dimensional Consideration: The substitute exhibits a maximum seated height of 3.160" (80.26mm) compared to 3.250" (82.55mm) for the original part. This 0.090" reduction in height is compatible with standard chassis mount applications and does not impact electrical performance or mechanical fit in typical motor run and PFC circuit configurations.

Frequently Asked Questions (FAQ)

Q: Can the 38FD37275A-F be used as a direct replacement for the 38FD37275-F?

A: Yes. The 38FD37275A-F is a direct equivalent substitute. All electrical specifications (27.5 µF capacitance, 370V AC rating, ±10% tolerance, polypropylene metallized dielectric) and mechanical parameters (radial can package, 0.813" lead spacing, quick connect termination) are identical. The substitute is the active production version of the same component family.

Q: What is the difference between these two part numbers?

A: The primary difference is product status. The 38FD37275-F is classified as obsolete, while the 38FD37275A-F is active production. The substitute also features a slightly reduced maximum seated height (3.160" versus 3.250"), which is compatible with standard installation requirements and does not affect electrical performance.

Q: Are there any compatibility concerns with the height difference?

A: No. The 38FD37275A-F has a maximum seated height of 3.160" (80.26mm), which is 0.090" shorter than the original 3.250" (82.55mm). This reduction is within acceptable tolerances for chassis mount applications and does not impact mechanical fit or electrical operation in motor run and power factor correction circuits.

Q: Do both parts have the same lead spacing?

A: Yes. Both the 38FD37275-F and 38FD37275A-F have identical lead spacing of 0.813" (20.64mm), ensuring compatibility with existing terminal board or PCB hole patterns without modification.

Q: Are regulatory and compliance certifications the same?

A: Yes. Both parts are ROHS3 compliant with identical regulatory classifications (ECCN: EAR99; HTSUS: 8532.25.0020) and moisture sensitivity level (MSL 1 - Unlimited). No compliance differences exist between the original and substitute parts.

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 27.5 µF capacitance are standard for industrial motor circuits and power factor correction systems in commercial and industrial equipment.

Q: Is the ±10% tolerance acceptable for my application?

A: The ±10% tolerance specification applies to both the original and substitute parts. Capacitance variation within this range is acceptable for motor run and PFC applications. If tighter tolerance is required, alternative part numbers with different tolerance specifications must be evaluated.

Q: What is the operating temperature range?

A: Both parts operate across -40°C to 70°C. This range accommodates typical industrial and commercial equipment environments. If operation outside this range is required, alternative components must be selected.
