106KXM050M Equivalent & Substitute Parts

Part Overview

The 106KXM050M is a 10 µF, 50 V aluminum electrolytic capacitor manufactured by Cornell Dubilier / Illinois Capacitor in the KXM series. This radial, through-hole component is rated for 2000 hours at 105°C and is designed for general-purpose applications. The part is currently active in production with 773 units in stock.

Equivalent and substitute parts are necessary when the original manufacturer discontinues production, when design requirements demand upgraded performance specifications, or when alternative sourcing is required for supply chain optimization. Several manufacturers produce functionally compatible alternatives with identical or enhanced electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 106KXM050M is determined by the following critical parameters:

Primary Matching Criteria:

• Capacitance: 10 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 50 V minimum (equal or higher acceptable)
• Operating Temperature: -55°C to 105°C (exact match required)
• Polarization: Polar (exact match required)
• Lead Spacing: 2.00 mm (exact match required)
• Package: Radial, Can through-hole (exact match required)

Secondary Performance Criteria:

• Lifetime @ 105°C: 2000 hours minimum
• ESR, Impedance, and Ripple Current: Lower values indicate improved performance
• RoHS3 Compliance: Required for regulatory alignment

Substitute parts are grouped into three categories:

Direct Equivalents (50 V Rating): Parts with identical voltage rating, capacitance, tolerance, and thermal specifications. These include UPJ1H100MDD, UPM1H100MDD, UPS1H100MDD, and UPV1H100MFD.

Upgraded Voltage Rating (63 V Rating): Parts with higher voltage ratings (ELXY630ELL100MEB5D, UPM1J100MDD, UPS1J100MDD) that maintain all other critical parameters. These provide enhanced voltage margin in the circuit.

Extended Lifetime (5000 Hrs): UPV1H100MFD offers 2.5× longer operational life at 105°C while maintaining 50 V rating and identical physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (50 V Applications):

UPM1H100MDD and UPS1H100MDD are parametric equivalents with identical 50 V rating and 2000-hour lifetime. Both maintain the 2.00 mm lead spacing and 12.50 mm height. UPM1H100MDD offers lower impedance (1.4 Ohm) compared to the main part (3.992 Ohm), resulting in improved high-frequency performance. Both parts are RoHS3 compliant. Note that both are marked as obsolete; availability should be confirmed before design commitment.

UPJ1H100MDD is a direct equivalent with slightly reduced height (12.00 mm) and lower impedance (2.0 Ohm). This part is also obsolete.

For Extended Operational Life (50 V Applications):

UPV1H100MFD extends the thermal lifetime to 5000 hours at 105°C while maintaining the 50 V rating, identical physical dimensions (12.50 mm height), and 2.00 mm lead spacing. This part is suitable for applications requiring enhanced reliability over extended service periods. Product status is obsolete.

For Upgraded Voltage Margin (63 V Applications):

ELXY630ELL100MEB5D is an active production part from Chemi-Con with 63 V rating, providing 26% higher voltage headroom. It maintains 10 µF capacitance, ±20% tolerance, and 2000-hour lifetime. Height increases to 13.00 mm; lead spacing remains 2.00 mm. This part carries AEC-Q200 automotive qualification and is suitable for applications where elevated voltage margin is required.

UPM1J100MDD and UPS1J100MDD both offer 63 V rating with 2000-hour lifetime and identical lead spacing. UPM1J100MDD provides superior impedance (1.06 Ohm) and is AEC-Q200 qualified. Both are obsolete.

Compliance Considerations:

All listed parts are RoHS3 compliant and REACH unaffected. Parts with AEC-Q200 qualification (UPM1H100MDD, ELXY630ELL100MEB5D, UPM1J100MDD) are suitable for automotive applications.

Frequently Asked Questions (FAQ)

Q: Can I use a 63 V rated capacitor in place of a 50 V rated capacitor?

A: Yes. A higher voltage rating is electrically compatible in circuits designed for lower voltage operation. The 63 V parts (ELXY630ELL100MEB5D, UPM1J100MDD, UPS1J100MDD) provide additional voltage margin without affecting circuit function. Physical dimensions must still be verified for PCB fit.

Q: What is the difference between the 2000-hour and 5000-hour lifetime parts?

A: Lifetime rating indicates the expected operational duration at maximum rated temperature (105°C) before capacitance degradation reaches specified limits. UPV1H100MFD (5000 hours) provides 2.5× longer service life than the main part and other 2000-hour alternatives. Selection depends on application reliability requirements and expected service duration.

Q: Why are many substitute parts marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. These parts may still be available through inventory channels but are not recommended for new designs. ELXY630ELL100MEB5D and the main part 106KXM050M remain in active production.

Q: Does impedance affect my circuit design?

A: Impedance values (ESR and reactance combined) influence high-frequency performance and ripple current handling. Lower impedance values (1.06 to 2.1 Ohm in substitutes) indicate better performance at higher frequencies compared to the main part (3.992 Ohm). For general-purpose applications at low frequencies, impedance differences are typically not critical.

Q: Are all substitute parts physically interchangeable?

A: Physical interchangeability requires matching lead spacing (2.00 mm for all listed parts) and PCB footprint compatibility. Most substitutes maintain 12.50 mm height; UPJ1H100MDD is 12.00 mm and ELXY630ELL100MEB5D is 13.00 mm. Verify PCB clearance before substitution.

Q: Which substitute part should I choose for a new design?

A: For new designs, select from active production parts: 106KXM050M (original) or ELXY630ELL100MEB5D (upgraded voltage rating). Active production status ensures long-term availability and supply chain stability. Obsolete parts should only be used when existing inventory must be maintained or when specific performance characteristics are required.

Q: What does RoHS3 compliance mean?

A: RoHS3 (Restriction of Hazardous Substances Directive 3) compliance indicates the part meets European environmental regulations restricting lead, mercury, cadmium, and other hazardous substances. All listed parts are RoHS3 compliant, suitable for applications with environmental compliance requirements.
