Substitute Part Grouping Explanation

Substitution eligibility for the UPM1J331MHD1AA is determined by strict equivalence across the following critical parameters:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 63 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package Type: Radial, Can (exact match required)
• Lead Spacing: 0.197" (5.00 mm) (exact match required)
• Physical Dimensions: 0.492" Dia × 1.063" Height (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -55°C ~ 105°C (exact match required)
• Lifetime @ Temperature: 5000 Hrs @ 105°C (exact match required)

The UPM1J331MHD qualifies as a parametric equivalent substitute. Both parts share identical electrical specifications, mechanical dimensions, and thermal ratings. The primary distinction is product status: UPM1J331MHD1AA is Active, while UPM1J331MHD is Not For New Designs.

Parameter Comparison

Engineering Selection Recommendations

The UPM1J331MHD1AA is the recommended primary selection for new designs due to its Active product status. This ensures long-term availability, ongoing manufacturer support, and compliance with current automotive standards.

The UPM1J331MHD qualifies as a direct parametric substitute for existing applications where the component is already in production. Both parts maintain identical electrical performance, mechanical compatibility, and AEC-Q200 automotive certification. The UPM1J331MHD is suitable for legacy system support or when existing inventory must be utilized.

Selection between these parts should be based on design phase and supply requirements rather than technical performance, as both meet the specified electrical and mechanical criteria.

Frequently Asked Questions (FAQ)

Q: Can UPM1J331MHD be used as a direct replacement for UPM1J331MHD1AA in new designs?

A: No. While UPM1J331MHD is electrically and mechanically equivalent, its Not For New Designs status makes it unsuitable for new product development. Use UPM1J331MHD1AA for new designs.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical lead spacing (0.197" / 5.00 mm), diameter (0.492" / 12.50 mm), and height (1.063" / 27.00 mm). They are mechanically interchangeable in through-hole PCB applications.

Q: Do both parts meet automotive compliance requirements?

A: Yes. Both UPM1J331MHD1AA and UPM1J331MHD carry AEC-Q200 ratings and are approved for automotive applications.

Q: What is the difference in impedance between these parts?

A: UPM1J331MHD1AA has 98 mOhms impedance, while UPM1J331MHD has 49 mOhms impedance. This difference reflects manufacturing variations within the same product family but does not affect substitution eligibility for standard applications.

Q: Can these capacitors be used interchangeably in PCB assembly?

A: Yes, provided the application does not depend on the specific impedance characteristics. Both parts have identical lead spacing and mounting requirements for through-hole assembly.
