Substitute Part Grouping Explanation

Substitution eligibility for the 126KXM063M is determined by the following mandatory parameters:

Electrical Parameters:

• Capacitance: 12 µF (exact match required)
• Voltage Rating: 63 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime: 2000 Hrs @ 105°C (exact match required)
• Operating Temperature: -55°C ~ 105°C (exact match required)
• Polarization: Polar (exact match required)

Mechanical Parameters:

• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• Lead Spacing: 0.079" (2.00mm) (exact match required)
• Size / Dimension: 0.197" Dia (5.00mm) (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)

All substitute parts listed meet these criteria and are therefore electrically and mechanically interchangeable with the primary part number 126KXM063M.

Engineering Selection Recommendations

Primary Substitute: ELXZ630ELL120MEB5D (Chemi-Con)

The ELXZ630ELL120MEB5D is the preferred substitute for the 126KXM063M. This part maintains Active product status and carries AEC-Q200 automotive qualification rating. All electrical and mechanical parameters align with the primary part. The height dimension of 0.512" (13.00mm) represents a 0.020" (0.50mm) increase compared to the primary part but remains within typical PCB layout tolerances for through-hole radial capacitors. Inventory availability is substantial at 3796 pieces.

Secondary Substitute: UPJ1J120MDD (Nichicon)

The UPJ1J120MDD is electrically and mechanically compatible with the 126KXM063M. However, this part carries Obsolete product status, indicating discontinued manufacturing. The impedance specification of 1.4 Ohms is lower than the primary part's 1.9 Ohms, and the height dimension of 0.472" (12.00mm) is 0.020" (0.50mm) shorter than the primary part. Selection of this part should be limited to applications where existing inventory must be consumed or where the lower impedance characteristic provides specific circuit benefit. Current inventory is 1968 pieces.

Both substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the primary part's regulatory classification.

Frequently Asked Questions (FAQ)

Q: Can ELXZ630ELL120MEB5D be used as a direct replacement for 126KXM063M?

A: Yes. The ELXZ630ELL120MEB5D meets all mandatory electrical and mechanical parameters. The height difference of 0.020" (0.50mm) is within standard PCB layout tolerances for radial through-hole capacitors and does not affect electrical performance or circuit functionality.

Q: Why is UPJ1J120MDD marked as Obsolete?

A: Obsolete status indicates that Nichicon has discontinued manufacturing of this part number. While existing inventory remains available, future procurement may not be possible. Selection should be based on current stock requirements and application timeline.

Q: Are there differences in ripple current ratings between the substitute parts?

A: Yes. The 126KXM063M specifies 59.2 mA @ 120 Hz and 148 mA @ 100 kHz. The ELXZ630ELL120MEB5D specifies 58 mA @ 120 Hz and 145 mA @ 100 kHz. The UPJ1J120MDD specifies 72 mA @ 120 Hz and 145 mA @ 10 kHz. These variations remain within acceptable operating parameters for general purpose applications with 12 µF, 63 V specifications.

Q: What is the significance of the impedance difference in UPJ1J120MDD?

A: The UPJ1J120MDD impedance of 1.4 Ohms is lower than the primary part's 1.9 Ohms. Lower impedance can reduce voltage ripple in power supply filtering applications. This characteristic does not prevent substitution but may provide circuit performance benefit in specific applications.

Q: Do all substitute parts maintain the same compliance certifications?

A: All parts listed are ROHS3 compliant and REACH unaffected. The ELXZ630ELL120MEB5D carries additional AEC-Q200 automotive qualification. All parts are suitable for applications requiring ROHS3 compliance.

Q: What is the maximum height variation among these parts?

A: The maximum height variation is 0.040" (1.00mm), ranging from 0.472" (12.00mm) for UPJ1J120MDD to 0.512" (13.00mm) for ELXZ630ELL120MEB5D. This variation is within standard PCB design tolerances for radial through-hole component placement.
