Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PSU8830B is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for a part to qualify as a direct substitute:

Electrical Parameters (Non-Negotiable):

• Capacitance: 88 µF
• Voltage Rating: 330 V
• Tolerance: 0%, +20%
• Polarization: Bi-Polar
• Operating Temperature Range: -40°C ~ 65°C

Mechanical Parameters (Non-Negotiable):

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

Compliance Parameters (Non-Negotiable):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The PSU8830A meets all substitution criteria. Height variation (3.375" vs. 4.375") is permissible when chassis clearance accommodates the taller profile, as this dimension does not affect electrical performance or core mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

PSU8830B Selection Criteria:

• Primary choice when chassis height is constrained to 3.375" (85.73 mm) maximum
• Both PSU8830B and PSU8830A maintain Active product status with full manufacturing support
• Both parts carry identical RoHS3 compliance and REACH unaffected status
• Inventory availability: PSU8830B (1138 pcs), PSU8830A (1198 pcs)

PSU8830A Selection Criteria:

• Direct substitute when chassis clearance permits 4.375" (111.13 mm) height
• Identical electrical performance and regulatory compliance
• Higher inventory availability supports extended production runs
• Taller profile may offer improved thermal dissipation characteristics in some applications

Compliance Assurance: Both parts satisfy ROHS3 compliance requirements and carry EAR99 ECCN classification. HTSUS code 8532.22.0055 applies uniformly to both components. No additional regulatory documentation is required for substitution.

Frequently Asked Questions (FAQ)

Q: Can PSU8830A replace PSU8830B in all applications?

A: PSU8830A is electrically and functionally equivalent to PSU8830B. The only difference is physical height (4.375" vs. 3.375"). Substitution is valid provided the chassis or mounting location accommodates the additional 1.0" height. Verify clearance before installation.

Q: Are there any electrical performance differences between PSU8830B and PSU8830A?

A: No. Both parts share identical capacitance (88 µF), voltage rating (330 V), tolerance (0%, +20%), polarization (Bi-Polar), and operating temperature range (-40°C ~ 65°C). Electrical behavior is equivalent.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both PSU8830B and PSU8830A are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (Unlimited). Regulatory compliance is identical.

Q: What is the significance of the QC terminal designation?

A: QC terminals refer to quick-connect terminal style for radial can capacitors. Both PSU8830B and PSU8830A use identical QC terminal construction, ensuring mechanical and electrical compatibility with standard motor start circuit designs.

Q: Can height difference affect circuit performance?

A: Height difference does not affect electrical circuit performance. Both parts deliver identical capacitance and voltage characteristics. Height variation only impacts physical installation space and thermal environment within the chassis.

Q: Which part should be selected for new designs?

A: For new designs, either part is acceptable. Selection should be based on available chassis height. If height is unconstrained, PSU8830A offers higher inventory availability. If space is limited to 3.375" maximum, PSU8830B is required.

Q: Are both parts actively manufactured?

A: Yes. Both PSU8830B and PSU8830A maintain Active product status with Cornell Dubilier Electronics, indicating ongoing manufacturing support and availability.
