108KBM010M Equivalent & Substitute Parts Reference

Part Overview

The 108KBM010M is a 1000 µF, 10 V aluminum electrolytic capacitor manufactured by Cornell Dubilier / Illinois Capacitor in the KBM series. This radial, through-hole component is rated for 6000 hours at 105°C and is designed for general-purpose applications requiring stable capacitance and low equivalent series resistance in compact form factors.

The part is currently Active in product status with 1148 pieces in stock. Equivalent and substitute parts are identified based on matching electrical specifications (capacitance, voltage rating, tolerance, and lifetime) and mechanical compatibility (lead spacing, case dimensions, and mounting type). Alternative models may be selected when the primary part is unavailable, when design upgrades to higher voltage ratings are required, or when extended operational lifetime is needed.

Substitute Part Grouping Explanation

Substitute parts for the 108KBM010M are organized into two categories based on electrical and mechanical compatibility:

Direct Substitutes (Same Voltage Rating - 10V)

Direct substitutes maintain identical electrical specifications: 1000 µF capacitance, 10 V voltage rating, ±20% tolerance, and -40°C to 105°C operating temperature range. All direct substitutes use through-hole radial can packaging with 0.197" (5.00 mm) lead spacing and 0.394" (10.00 mm) case diameter. These parts differ in manufacturer, series designation, lifetime rating, and physical height. Direct substitutes are selected when the original part is unavailable or when inventory constraints require alternative sourcing from qualified manufacturers.

The key parameters determining direct substitution eligibility are:

Capacitance: 1000 µF (exact match required)
Voltage Rating: 10 V (exact match required)
Tolerance: ±20% (exact match required)
Lead Spacing: 0.197" / 5.00 mm (exact match required)
Case Diameter: 0.394" / 10.00 mm (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)

Upgrade Options (Higher Voltage Rating - 16V)

Upgrade parts increase the voltage rating from 10 V to 16 V while maintaining 1000 µF capacitance and ±20% tolerance. These components provide enhanced voltage margin and are suitable for applications where circuit design allows higher-rated components or where voltage stress reduction is desired. Upgrade parts maintain identical lead spacing (0.197" / 5.00 mm) and case diameter (0.394" / 10.00 mm) but may have different physical heights and improved lifetime ratings (10000 hours at 105°C versus 6000 hours).

The key parameters determining upgrade eligibility are:

Capacitance: 1000 µF (exact match required)
Voltage Rating: 16 V (higher rating acceptable in same circuit)
Tolerance: ±20% (exact match required)
Lead Spacing: 0.197" / 5.00 mm (exact match required)
Case Diameter: 0.394" / 10.00 mm (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)

Engineering Selection Recommendations

For Direct Substitution (10V Rating)

When selecting a direct substitute for the 108KBM010M, prioritize parts with Active product status. The following direct substitutes are recommended in order of availability and compliance status:

10ZLH1000MEFC10X12.5 (Rubycon ZLH series) - Active status, highest inventory (399,821 pcs), 10000-hour lifetime at 105°C, reduced physical height (14.00 mm), ROHS3 compliant. This part provides extended operational life compared to the original specification.
EEU-FS1A102 (Panasonic FS-A series) - Active status, 4631 pcs in stock, 6000-hour lifetime matching original specification, reduced physical height (14.00 mm), ROHS3 compliant.
EKZH100ELL102MJC5S (Chemi-Con KZH series) - Active status, 2546 pcs in stock, 6000-hour lifetime, reduced physical height (14.00 mm), ROHS3 compliant.
10ZLS1000MEFC10X12.5 (Rubycon ZLS series) - Active status, 1859 pcs in stock, 6000-hour lifetime, reduced physical height (14.00 mm), ROHS3 compliant.

Parts marked "Not For New Designs" (UHE1A102MPD6 and UHV1A102MPD from Nichicon) are available but should not be selected for new circuit designs due to obsolescence trajectory.

For Voltage Upgrade (16V Rating)

When circuit design permits higher voltage rating, upgrade options provide enhanced reliability margins and extended lifetime:

16ZLJ1000MCE10X16 (Rubycon ZLJ series) - Active status, highest inventory (15,116 pcs), 10000-hour lifetime at 105°C, maintains original height (17.50 mm), ROHS3 compliant.
16ZLH1000MEFC10X16 (Rubycon ZLH series) - Active status, 8305 pcs in stock, 10000-hour lifetime, maintains original height (17.50 mm), ROHS3 compliant.
16YXJ1000M10X16 (Rubycon YXJ series) - Active status, 6090 pcs in stock, 10000-hour lifetime, maintains original height (17.50 mm), ROHS3 compliant.
16ZLJ1000M10X16 (Rubycon ZLJ series) - Active status, 1181 pcs in stock, 10000-hour lifetime, maintains original height (17.50 mm), ROHS3 compliant.

All recommended parts are ROHS3 compliant and suitable for applications requiring regulatory compliance with hazardous substance restrictions.

Frequently Asked Questions (FAQ)

Q: Can I use a 16V rated capacitor in place of a 10V rated capacitor?

A: Yes. A higher voltage-rated capacitor is electrically compatible with circuits designed for lower voltage ratings. The 16V upgrade options (16YXJ1000M10X16, 16ZLH1000MEFC10X16, 16ZLJ1000M10X16, 16ZLJ1000MCE10X16) are direct mechanical and electrical substitutes that provide additional voltage margin. However, verify that circuit board layout and component clearance accommodate any height differences.

Q: What is the difference between direct substitutes and upgrade options?

A: Direct substitutes maintain the original 10V voltage rating and are selected when the 108KBM010M is unavailable. Upgrade options increase the voltage rating to 16V, providing enhanced reliability and extended lifetime (10000 hours versus 6000 hours at 105°C). Upgrade options are selected when circuit design allows higher-rated components or when improved long-term reliability is required.

Q: Are all substitute parts mechanically compatible with the original PCB footprint?

A: All direct substitutes and upgrade options maintain identical lead spacing (0.197" / 5.00 mm) and case diameter (0.394" / 10.00 mm), ensuring PCB footprint compatibility. However, physical height varies: direct substitutes range from 14.00 mm to 17.50 mm, while upgrade options are 17.50 mm. Verify component clearance in the vertical direction before assembly, particularly for direct substitutes with reduced height (10ZLH1000MEFC10X12.5, 10ZLS1000MEFC10X12.5, EEU-FS1A102, EKZH100ELL102MJC5S).

Q: Why are some substitute parts marked "Not For New Designs"?

A: Parts designated "Not For New Designs" (UHE1A102MPD6, UHV1A102MPD) indicate that the manufacturer has discontinued active development and is transitioning these products to end-of-life status. While inventory remains available, these parts should not be selected for new circuit designs. Use Active-status alternatives instead.

Q: What is the significance of lifetime rating differences (6000 hours versus 10000 hours at 105°C)?

A: Lifetime rating indicates the expected operational duration at maximum rated temperature (105°C) before capacitance degradation reaches specified limits. Parts rated for 10000 hours provide extended operational margin compared to 6000-hour parts. For applications operating continuously at elevated temperatures, 10000-hour parts (10ZLH1000MEFC10X12.5 and all 16V upgrade options) are preferred.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All direct substitutes and upgrade options listed are ROHS3 compliant, meeting regulatory requirements for hazardous substance restrictions in electronic equipment.

Q: Can I mix different substitute part numbers in the same circuit or assembly?

A: Yes. All substitute parts meet identical electrical specifications (1000 µF, ±20% tolerance, matching voltage rating, -40°C to 105°C operating range) and are mechanically compatible. Mixing different manufacturers or series in the same circuit is acceptable from an electrical standpoint. However, document part selection in design records for traceability and future maintenance.

Q: What inventory considerations should guide part selection?

A: Select parts based on availability and project timeline. 10ZLH1000MEFC10X12.5 (Rubycon) offers the highest inventory (399,821 pcs) among direct substitutes. For upgrade options, 16ZLJ1000MCE10X16 (Rubycon) provides the largest stock (15,116 pcs). Consult current inventory status before finalizing procurement decisions.
