Substitute parts are grouped into three categories based on product status and performance characteristics:

Direct Substitutes (Active Status): Parts meeting all electrical and mechanical parameters with current production status. These include 100PX1MEFC5X11 (Rubycon PX series), EKMG101ELL1R0ME11D (Chemi-Con KMG series), and EKMQ101ELL1R0ME11D (Chemi-Con KMQ series). All maintain 1000-hour lifetime at 105°C.

Upgrade Option (Enhanced Performance): The 105KXM100M (Cornell Dubilier KXM series) provides extended lifetime of 2000 hours at 105°C while maintaining all core electrical and mechanical parameters.

Alternative Option (Extended Availability): The SEK010M100ST (Cornell Dubilier Electronics SEK series) offers 2000-hour lifetime at 105°C with slightly increased height (0.512" vs. 0.492") and different moisture sensitivity rating.

Engineering Selection Recommendations

For Direct Replacement (Equivalent Performance): Select 100PX1MEFC5X11, EKMG101ELL1R0ME11D, or EKMQ101ELL1R0ME11D. All three parts are active production items with ROHS3 compliance and maintain the original 1000-hour lifetime specification. These parts are electrically and mechanically equivalent to the obsolete ECA-2AHG010. Height variations of 0.492" (12.50 mm) versus the original 0.472" (12.00 mm) require PCB layout verification for clearance.

For Enhanced Reliability (Upgrade Path): Select 105KXM100M for applications requiring extended operational life. This part doubles the lifetime rating to 2000 hours at 105°C while maintaining all core electrical and mechanical parameters. ROHS3 compliance and active production status support long-term supply continuity.

For Maximum Availability: Select SEK010M100ST from Cornell Dubilier Electronics. This part offers the highest inventory availability (10,874 pcs) with 2000-hour lifetime at 105°C and ROHS3 compliance. The increased height of 0.512" (13.00 mm) requires PCB layout verification.

All substitute parts carry REACH Unaffected and EAR99 ECCN classifications matching the original part.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different height? A: Height differences exist between the original ECA-2AHG010 (0.472" / 12.00 mm) and substitute parts (0.492" to 0.512" / 12.50 to 13.00 mm). PCB layout must be verified to ensure adequate clearance above the capacitor. If vertical space is constrained, the 100PX1MEFC5X11 at 0.492" (12.50 mm) provides the smallest height increase.

Q: What is the difference between direct substitutes and upgrade options? A: Direct substitutes (100PX1MEFC5X11, EKMG101ELL1R0ME11D, EKMQ101ELL1R0ME11D) maintain the original 1000-hour lifetime at 105°C. Upgrade options (105KXM100M, SEK010M100ST) extend lifetime to 2000 hours at 105°C, providing enhanced reliability for long-term applications. All parts meet the same electrical specifications.

Q: Are all substitute parts RoHS compliant? A: Yes. All active substitute parts listed are ROHS3 compliant. The original ECA-2AHG010 RoHS status is not specified due to its obsolete classification.

Q: Which substitute part has the best ripple current performance? A: EKMG101ELL1R0ME11D and EKMQ101ELL1R0ME11D both provide 37.5 mA ripple current at 100 kHz, exceeding the original ECA-2AHG010 specification of 28 mA at 100 kHz. 100PX1MEFC5X11 provides 22.5 mA at 10 kHz. Selection depends on the specific frequency requirements of your application.

Q: Can I mix different substitute parts in the same design? A: Yes. All substitute parts are electrically equivalent and mechanically compatible with the same PCB footprint (0.079" / 2.00 mm lead spacing, 0.197" / 5.00 mm diameter). However, height variations require consistent PCB layout clearance verification across all component positions.

Q: What is the moisture sensitivity level of these parts? A: Direct substitutes and upgrade options are rated as Not Applicable for moisture sensitivity. SEK010M100ST is rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions.
