Substitute Part Grouping Explanation

Substitution logic for the 107RZM025M is based on the following critical parameters that must remain constant or be enhanced:

Fixed Parameters (Must Match):

• Capacitance: 100 µF
• Voltage Rating: 25 V minimum (upgrades to 35 V are acceptable)
• Tolerance: ±20%
• Lifetime: 2000 Hrs @ 105°C
• Operating Temperature: -55°C to 105°C
• Polarization: Polar
• Lead Spacing: 0.098" (2.50mm)
• Size / Dimension: 0.248" Dia (6.30mm)
• Mounting Type: Through Hole
• Package / Case: Radial, Can

Variable Parameters (May Differ):

• ESR @ 120Hz (lower values indicate improved performance)
• Impedance (lower values indicate improved performance)
• Ripple Current ratings (higher values indicate improved performance)
• Height - Seated (minor variations acceptable within mechanical constraints)
• Manufacturer and Series designation
• Product Status (Active, Obsolete, or Discontinued)
• Compliance certifications (RoHS, REACH, AEC-Q200)

Substitute parts are grouped into three categories:

1. Parametric Equivalents: Parts with identical electrical specifications and form factor
2. Direct Manufacturers: Parts from alternative manufacturers with equivalent or superior electrical characteristics
3. Upgrades: Parts with higher voltage ratings or improved performance metrics

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute - Active Status:

The 107KXM025M (Cornell Dubilier / Illinois Capacitor, KXM series) is the recommended primary substitute. This part maintains Active product status, identical electrical specifications to the 107RZM025M, and demonstrates superior electrical performance with lower ESR (2.321 Ohm vs. 2.653 Ohm) and significantly lower impedance (410 mOhm vs. 1200 mOhm). Inventory availability is substantially higher at 26,663 pieces. Both parts are ROHS3 Compliant and share identical mechanical dimensions and lead spacing.

Secondary Substitute - Automotive Grade:

The ELXZ250ELL101MFB5D (Chemi-Con, LXZ series) is an Active product with AEC-Q200 automotive qualification. This part offers the lowest impedance (250 mOhm) among all substitutes, indicating superior high-frequency performance. Height is 13.00mm versus 12.50mm for the main part, representing a 0.50mm increase that must be verified against PCB layout constraints. This part is suitable for applications requiring automotive-grade reliability.

Voltage Upgrade Option:

The UKA1V101MED (Nichicon, UKA series) provides a voltage upgrade to 35 V while maintaining 100 µF capacitance and identical form factor. This part is classified as Obsolete but maintains 3,557 pieces in inventory. The higher voltage rating provides additional design margin for circuits operating near the 25 V limit.

Compatibility Notes:

All substitute parts maintain the following specifications identical to 107RZM025M:

• Capacitance: 100 µF
• Tolerance: ±20%
• Operating Temperature: -55°C to 105°C
• Lifetime: 2000 Hrs @ 105°C
• Lead Spacing: 0.098" (2.50mm)
• Size / Dimension: 0.248" Dia (6.30mm)
• Mounting Type: Through Hole
• Package / Case: Radial, Can
• RoHS Status: ROHS3 Compliant

Frequently Asked Questions (FAQ)

Q: Can 107KXM025M directly replace 107RZM025M without circuit modification?

A: Yes. Both parts are manufactured by Cornell Dubilier / Illinois Capacitor with identical capacitance (100 µF), voltage rating (25 V), tolerance (±20%), and mechanical dimensions. The 107KXM025M exhibits lower ESR and impedance, which improves circuit performance without requiring design changes.

Q: What is the significance of the lower impedance in 107KXM025M and ELXZ250ELL101MFB5D?

A: Lower impedance indicates reduced resistance to AC current flow at operating frequencies. The 107KXM025M (410 mOhm) and ELXZ250ELL101MFB5D (250 mOhm) provide better high-frequency filtering and reduced voltage ripple compared to the main part (1200 mOhm). This is particularly beneficial in power supply and audio applications.

Q: Is the 0.50mm height difference of ELXZ250ELL101MFB5D (13.00mm vs. 12.50mm) a concern?

A: The height difference must be evaluated against specific PCB layout constraints. If the application has clearance limitations or height restrictions, this 0.50mm increase may require design verification. For most general purpose applications with standard PCB spacing, this difference is not problematic.

Q: Why are some substitute parts listed as Obsolete?

A: Obsolete parts (UKA1E101MED, UKA1V101MED, UPS1E101MED) are no longer manufactured by their respective suppliers but remain available in current inventory. These parts are suitable for replacement applications where existing stock is available, but should not be specified for new designs requiring long-term supply assurance.

Q: Can UKA1V101MED (35V) be used in place of 107RZM025M (25V)?

A: Yes, from an electrical compatibility standpoint. The higher voltage rating (35V vs. 25V) provides additional design margin and does not degrade circuit performance. However, the UKA1V101MED is Obsolete status, so long-term availability cannot be guaranteed. Use this part only when inventory is confirmed and supply continuity is not critical.

Q: What compliance certifications apply to all substitute parts?

A: All listed substitute parts are ROHS3 Compliant and REACH Unaffected. The ELXZ250ELL101MFB5D additionally carries AEC-Q200 automotive qualification, making it suitable for automotive and high-reliability applications.

Q: Are there mechanical compatibility issues with any substitute part?

A: All substitute parts maintain identical lead spacing (0.098" / 2.50mm), diameter (0.248" / 6.30mm), and mounting type (Through Hole, Radial Can package). The only dimensional variation is the ELXZ250ELL101MFB5D height (13.00mm vs. 12.50mm standard). Verify PCB clearance before selection if height-constrained applications are involved.

Q: Which substitute offers the best overall performance?

A: The ELXZ250ELL101MFB5D provides the lowest impedance (250 mOhm) and includes AEC-Q200 automotive qualification. For general purpose applications prioritizing electrical performance and compliance, the 107KXM025M is recommended due to Active status, superior availability (26,663 pcs), and lower ESR (2.321 Ohm).
