Substitute Part Grouping Explanation

Substitution for the B41002A4226M is determined by strict equivalence across the following critical parameters:

• Capacitance: 22 µF (exact match required)
• Voltage Rating: 16 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package Type: Radial, Can (exact match required)
• Lead Spacing: 0.059" (1.50mm) (exact match required)
• Physical Dimensions: 0.157" Dia × 0.315" Height (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Polarization: Polar (exact match required)

Two substitute parts meet these criteria:

1. 226PUM016M (Cornell Dubilier / Illinois Capacitor) — Upgrade substitute with extended lifetime rating
2. 16MS722MEFC4X7 (Rubycon) — Parametric equivalent with comparable specifications

Engineering Selection Recommendations

226PUM016M (Recommended Primary Substitute)

The 226PUM016M is the preferred substitute for the B41002A4226M. This part is currently in active production status, ensuring long-term availability and supply chain stability. It meets all electrical and mechanical parameters of the original part and provides an extended lifetime rating of 2000 hours at 85°C compared to the original 1000-hour specification. The part carries ROHS3 compliance and is available in bulk packaging. The specified ESR of 12.057 Ohm at 120 Hz provides measurable performance data for circuit design verification.

16MS722MEFC4X7 (Secondary Equivalent)

The 16MS722MEFC4X7 from Rubycon is a parametric equivalent that matches all critical electrical and mechanical specifications of the B41002A4226M. This part is currently obsolete, similar to the original component. The ripple current rating is marginally higher at 42 mA compared to 40 mA, and the lifetime rating matches the original at 1000 hours at 85°C. This part is suitable for direct replacement in existing designs but does not offer the supply chain advantages of the active 226PUM016M.

Frequently Asked Questions (FAQ)

Q: Can 226PUM016M be used as a direct replacement for B41002A4226M?

A: Yes. The 226PUM016M is electrically and mechanically equivalent to the B41002A4226M across all critical parameters: 22 µF capacitance, 16 V voltage rating, ±20% tolerance, identical physical dimensions, lead spacing, and through-hole mounting configuration. The extended 2000-hour lifetime at 85°C provides improved reliability compared to the original 1000-hour specification.

Q: What is the difference between the two substitute parts?

A: Both 226PUM016M and 16MS722MEFC4X7 are electrically and mechanically equivalent to the B41002A4226M. The primary distinction is product status: 226PUM016M is in active production, while 16MS722MEFC4X7 is obsolete. For new designs and ongoing production, 226PUM016M is the preferred choice due to supply chain availability.

Q: Are there any physical compatibility concerns when substituting these parts?

A: No. All three parts share identical lead spacing (0.059" / 1.50mm), case diameter (0.157" / 4.00mm), and maximum seated height (0.315" / 8.00mm). PCB footprints and mounting holes designed for the B41002A4226M are fully compatible with both substitute parts.

Q: Does the higher ripple current rating of 16MS722MEFC4X7 affect circuit performance?

A: No. The 16MS722MEFC4X7 ripple current rating of 42 mA at 120 Hz exceeds the original specification of 40 mA. This represents improved performance capability and does not create compatibility issues in circuits designed for the original 40 mA specification.

Q: What compliance certifications apply to these substitute parts?

A: All three parts—B41002A4226M, 226PUM016M, and 16MS722MEFC4X7—are ROHS3 compliant. The 226PUM016M carries additional REACH Unaffected status. All parts are classified under ECCN EAR99 and HTSUS 8532.22.0020.
