PSU7230C Equivalent & Substitute Parts Reference

Part Overview

The PSU7230C is a 72 µF, 330 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in the PSU series. This radial, can-style component with QC terminals is designed for motor start applications and operates across a temperature range of -40°C to 65°C. The part is currently active in production with 1,098 units in stock. Substitute parts are identified when inventory constraints, lead time requirements, or application-specific needs necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the PSU7230C is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Non-Negotiable):

• Capacitance: 72 µF (exact match required)
• Voltage Rating: 330 V (exact match required)
• Tolerance: 0%, +20% (exact match required)
• Polarization: Bi-Polar (exact match required)
• Operating Temperature Range: -40°C ~ 65°C (exact match required)

Mechanical Parameters (Non-Negotiable):

• Package Type: Radial, Can - QC Terminals (exact match required)
• Mounting Type: Chassis Mount (exact match required)
• Diameter: 1.813" (46.05 mm) (exact match required)

Regulatory & Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Manufacturer: Cornell Dubilier Electronics (CDE) (same manufacturer preferred for consistency)

Application Context:

• Motor Start applications (exact match required)

The PSU7230B qualifies as a direct substitute based on matching all electrical, mechanical, and regulatory parameters. Height variation (4.435" vs. 3.375") is permissible when chassis clearance accommodates the taller dimension.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The PSU7230C and PSU7230B are electrically and mechanically equivalent components from the same manufacturer and series. Selection between these parts is based on:

1. Inventory Availability: PSU7230C has 1,098 units in stock; PSU7230B has 678 units in stock. Choose based on procurement timeline and supply chain requirements.

2. Physical Space Constraints: The PSU7230B has a maximum seated height of 4.435" (112.65 mm) compared to the PSU7230C at 3.375" (85.73 mm). Verify chassis clearance before selecting the taller variant.

3. Regulatory Compliance: Both parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards for motor start applications.

4. Product Status: Both parts are Active in production, ensuring long-term availability and support.

Substitution Validity:

The PSU7230B is a valid direct substitute for the PSU7230C in motor start applications where the increased height does not create mechanical interference. No derating, performance adjustment, or additional testing is required when substituting between these parts, provided chassis dimensions accommodate the height difference.

Frequently Asked Questions (FAQ)

Q: Can PSU7230B replace PSU7230C in my motor start circuit?

A: Yes. The PSU7230B is electrically identical to the PSU7230C with matching capacitance (72 µF), voltage rating (330 V), tolerance (0%, +20%), polarization (Bi-Polar), and operating temperature range (-40°C ~ 65°C). The only difference is physical height. Substitution is valid if your chassis accommodates the 4.435" (112.65 mm) seated height of the PSU7230B.

Q: What is the height difference between these parts?

A: The PSU7230C has a maximum seated height of 3.375" (85.73 mm), while the PSU7230B measures 4.435" (112.65 mm). This 1.06" (26.92 mm) difference must be considered during mechanical layout verification.

Q: Are both parts RoHS compliant?

A: Yes. Both the PSU7230C and PSU7230B are ROHS3 Compliant and REACH Unaffected, meeting current environmental regulations for electronic components.

Q: Do these parts have the same terminal type?

A: Yes. Both parts use QC (Quick Connect) terminals in a radial, can-style package, ensuring identical electrical connection methods.

Q: Which part should I choose if both are available?

A: Selection depends on your specific requirements. If chassis space is limited, choose the PSU7230C (shorter height). If height is not a constraint and you need immediate availability, either part is suitable. Both are Active products from Cornell Dubilier Electronics with equivalent performance in motor start applications.

Q: Can I use these parts interchangeably in production?

A: Yes, provided your PCB layout and chassis design accommodate the height difference of the PSU7230B. Both parts meet identical electrical specifications and regulatory requirements for motor start applications.
