Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following mandatory parameters:

Electrical Parameters (Non-Negotiable):

• Capacitance: 10000 µF (exact match required)
• Voltage Rating: 16 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Operating Temperature Range: -55°C to 105°C (substitute must support this range)

Mechanical Parameters (Non-Negotiable):

• Package Type: Radial, Can (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.295" (7.50mm) (exact match required)
• Diameter: 0.709" (18.00mm) (exact match required)

Regulatory Parameters:

• RoHS3 Compliance (all substitutes must comply)
• REACH Status: REACH Unaffected (all substitutes must comply)

Performance Parameters (Variable - Enhancement Allowed):

• Lifetime @ Temperature: 3000 Hrs @ 105°C (minimum baseline; higher values indicate enhanced reliability)
• ESR / Impedance: Lower values indicate improved performance characteristics
• Ripple Current Ratings: Higher values indicate enhanced current handling capability

The two substitute parts listed below satisfy all mandatory electrical, mechanical, and regulatory requirements. They differ in performance characteristics and product status, which determine their application suitability.

Engineering Selection Recommendations

ELXZ160ELL103MM40S (Chemi-Con LXZ Series) - Upgrade Substitute:

This part is classified as Active product status and qualifies as an upgrade substitute for the 109RZM016M. The ELXZ160ELL103MM40S maintains all mandatory electrical and mechanical parameters while providing enhanced performance characteristics. The lifetime rating of 8000 Hrs @ 105°C exceeds the baseline 3000 Hrs specification, representing a 167% improvement in thermal endurance. The impedance of 15 mOhms is significantly lower than the main part's 72 mOhms, indicating superior high-frequency performance and reduced voltage ripple effects. The part carries AEC-Q200 automotive qualification, confirming compliance with automotive-grade reliability standards. All regulatory requirements (ROHS3, REACH Unaffected) are satisfied. This substitute is suitable for new designs and applications requiring extended operational life or enhanced ripple current handling.

UPS1C103MHD (Nichicon UPS Series) - Parametric Equivalent:

This part is classified as Not For New Designs product status and qualifies as a parametric equivalent substitute for the 109RZM016M. The UPS1C103MHD maintains all mandatory electrical and mechanical parameters with identical lifetime rating of 3000 Hrs @ 105°C. The impedance of 27 mOhms is lower than the main part's 72 mOhms, providing improved performance. However, the Not For New Designs status indicates this part is in end-of-life phase and should not be selected for new product development. This substitute is appropriate only for legacy system maintenance, repair operations, or applications where existing inventory must be maintained with compatible components. All regulatory requirements (ROHS3, REACH Unaffected) are satisfied.

Frequently Asked Questions (FAQ)

Q: Can ELXZ160ELL103MM40S be used as a direct replacement for 109RZM016M in existing designs?

A: Yes. The ELXZ160ELL103MM40S maintains identical electrical specifications (10000 µF, 16 V, ±20% tolerance), mechanical dimensions (0.709" diameter, 0.295" lead spacing), and mounting configuration (through-hole radial can). The enhanced lifetime rating and lower impedance represent performance improvements that do not compromise compatibility. PCB layout and circuit design require no modification.

Q: What is the significance of the "Not For New Designs" status on UPS1C103MHD?

A: This designation indicates the part is in end-of-life phase and manufacturer support for new applications is discontinued. While the part remains electrically and mechanically compatible, it should not be selected for new product development. It is appropriate only for sustaining production of existing products or field repairs where component replacement is necessary.

Q: How do impedance differences affect circuit performance?

A: Impedance (measured in mOhms) directly influences voltage ripple and transient response characteristics. The ELXZ160ELL103MM40S at 15 mOhms provides superior ripple attenuation compared to the 109RZM016M at 72 mOhms. Lower impedance reduces voltage noise and improves power supply stability, particularly beneficial in noise-sensitive applications. The UPS1C103MHD at 27 mOhms offers intermediate performance.

Q: Are there height clearance considerations when substituting these parts?

A: The ELXZ160ELL103MM40S has a maximum seated height of 1.634" (41.50mm), which is 0.020" (0.50mm) shorter than both the 109RZM016M and UPS1C103MHD at 1.654" (42.00mm). This minor difference is negligible for most PCB layouts. However, designs with tight vertical clearance constraints should verify the reduced height does not create assembly or thermal management issues.

Q: Which substitute should be selected for automotive applications?

A: The ELXZ160ELL103MM40S carries AEC-Q200 automotive qualification and is designated for automotive applications. The 109RZM016M and UPS1C103MHD are specified for general-purpose use. If automotive-grade reliability certification is required, ELXZ160ELL103MM40S is the appropriate selection.

Q: What is the impact of the 8000 Hrs vs. 3000 Hrs lifetime rating?

A: Lifetime rating specifies the expected operational duration at maximum rated temperature (105°C) before capacitance degradation reaches 80% of initial value. The ELXZ160ELL103MM40S at 8000 Hrs provides 167% longer service life under thermal stress compared to the baseline 3000 Hrs specification. This extended rating improves system reliability in high-temperature environments and reduces field failure risk over extended operational periods.

Q: Are all three parts RoHS3 compliant?

A: Yes. The 109RZM016M, ELXZ160ELL103MM40S, and UPS1C103MHD are all ROHS3 Compliant and REACH Unaffected. They satisfy current environmental and regulatory requirements for commercial and industrial applications in regulated markets.
