Engineering Selection Recommendations

106AXZ025M Selection Criteria:

• General purpose applications with standard thermal cycling requirements
• Designs with existing PCB layout constraints accommodating 5.90mm maximum height
• Applications where 2000-hour lifetime at 105°C meets operational specifications
• Circuits with 40 mA ripple current requirements at 120 Hz

ATB106M025 Selection Criteria:

• Bypass and decoupling applications requiring enhanced ripple current handling (63 mA @ 120 Hz)
• Designs benefiting from reduced ESR (18.57 Ohm vs. 23.21 Ohm)
• Extended thermal life requirement (3000 hours @ 105°C vs. 2000 hours)
• PCB layouts with 5.70mm maximum height clearance
• High-frequency ripple current applications (90 mA @ 100 kHz capability)

Both parts maintain Active product status and full ROHS3 compliance. Selection between these parts depends on application-specific ripple current demands, thermal cycling duration, and available PCB clearance.

Frequently Asked Questions (FAQ)

Q: Can ATB106M025 directly replace 106AXZ025M in all applications?

A: ATB106M025 is electrically and mechanically compatible as a direct substitute. Both parts share identical capacitance (10 µF), voltage rating (25 V), tolerance (±20%), operating temperature range (-55°C ~ 105°C), and surface mount package specifications. The substitute offers improved ESR and extended thermal lifetime. Verify PCB layout accommodates the 0.189" W (4.80mm) land size versus the original 0.169" W (4.30mm).

Q: What are the physical differences between these parts?

A: Height difference is 0.008" (0.20mm), with ATB106M025 being slightly shorter (5.70mm vs. 5.90mm). Surface mount land size width differs by 0.020" (0.50mm). Both maintain identical 0.157" (4.00mm) diameter. These variations are within standard SMD assembly tolerances and do not affect functional compatibility in most applications.

Q: How do ESR values affect circuit performance?

A: ESR (Equivalent Series Resistance) directly impacts voltage ripple and heat generation. ATB106M025 provides 20% lower ESR (18.57 Ohm vs. 23.21 Ohm @ 120Hz), resulting in reduced voltage ripple and lower dissipation in high-ripple-current applications. This improvement is particularly beneficial in bypass and decoupling circuits.

Q: What is the significance of ripple current ratings?

A: Ripple current capacity determines the maximum AC current the capacitor can safely handle without exceeding temperature limits. ATB106M025 supports 63 mA @ 120 Hz and 90 mA @ 100 kHz, compared to 106AXZ025M at 40 mA @ 120 Hz. Higher ripple current capability enables use in more demanding power supply and filtering applications.

Q: Are both parts RoHS compliant?

A: Yes. Both 106AXZ025M and ATB106M025 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level and REACH Unaffected status, meeting current environmental and regulatory requirements.

Q: What does the 3000 Hrs @ 105°C lifetime specification mean?

A: This indicates the capacitor maintains its electrical characteristics within specified tolerances for 3000 hours of continuous operation at 105°C ambient temperature. ATB106M025 provides 50% extended lifetime (3000 hours vs. 2000 hours), beneficial for applications requiring long-term reliability in elevated temperature environments.
