Key Parameters

Substitute Part Grouping Explanation

Substitution of the PVC16227 is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Capacitance value: 2700 pF (exact match required)
• Voltage rating - DC: Minimum 1600V (1.6kV)
• Dielectric material: Polypropylene (PP) construction

Mechanical Compatibility Criteria:

• Mounting type: Through Hole
• Package configuration: Radial
• Termination style: PC Pins

Compliance Requirements:

• RoHS3 compliance
• REACH unaffected status

The substitute part B32671L1272J000 satisfies all critical electrical parameters with identical capacitance and voltage rating. The polypropylene dielectric material and radial through-hole configuration provide mechanical compatibility. Enhanced tolerance (±5% versus ±10%) and higher AC voltage rating (600V versus 475V) represent improvements over the original specification.

Parameter Comparison

Engineering Selection Recommendations

The B32671L1272J000 is a direct electrical substitute for the obsolete PVC16227. Both components maintain identical capacitance (2700 pF) and DC voltage rating (1.6 kV), satisfying the core functional requirements.

The substitute part offers the following advantages:

• Active Product Status: B32671L1272J000 is currently in active production, ensuring long-term availability and supply chain continuity.
• Enhanced Tolerance: ±5% tolerance provides tighter capacitance control compared to the ±10% specification of the original part.
• Improved AC Rating: 600V AC rating exceeds the original 475V specification, providing additional margin in AC applications.
• Extended Temperature Range: Operating range extends to 110°C, compared to 105°C for the original part.
• Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status.

Physical dimensions differ between the two parts. The substitute exhibits a more compact footprint (13.00mm L x 5.00mm W versus 10.70mm Dia x 31.80mm L) with reduced lead spacing (10.00mm versus 24.60mm). PCB layout modifications are required to accommodate the dimensional change.

Frequently Asked Questions (FAQ)

Q: Can B32671L1272J000 be used as a direct replacement for PVC16227 in existing designs?

A: Electrical substitution is valid. The capacitance value and DC voltage rating are identical. However, physical dimensions and lead spacing differ significantly, requiring PCB layout modification. Verify that the reduced footprint and 10.00mm lead spacing are compatible with the target application.

Q: What is the significance of the metallized polypropylene construction in the substitute part?

A: The B32671L1272J000 uses metallized polypropylene film, which differs from the standard polypropylene construction of the PVC16227. Metallized construction provides self-healing properties and is optimized for high-frequency and switching applications. Both constructions maintain the same dielectric material classification and voltage rating.

Q: Are there any compliance or regulatory differences between the two parts?

A: Both components are ROHS3 compliant and REACH unaffected. No regulatory barriers exist for substitution from a compliance perspective.

Q: How does the tolerance difference affect circuit performance?

A: The substitute part offers ±5% tolerance compared to the original ±10%. This tighter tolerance reduces capacitance variation across the production range, potentially improving circuit stability and performance consistency. Applications requiring loose tolerance specifications will not be negatively affected by this improvement.

Q: What considerations apply to the lead spacing change?

A: The original PVC16227 has 24.60mm lead spacing, while the B32671L1272J000 has 10.00mm lead spacing. This dimensional difference requires PCB redesign. Verify that the new lead spacing is compatible with the target PCB layout and that no mechanical interference occurs with adjacent components.

Q: Is the extended operating temperature range of the substitute part significant?

A: The B32671L1272J000 operates to 110°C compared to 105°C for the original part. This 5°C extension provides additional thermal margin in high-temperature environments. Applications operating near the upper temperature limit may benefit from this specification improvement.
