Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 109LBA016M2BD are qualified based on strict electrical and mechanical parameter matching:

Critical Matching Parameters:

• Capacitance: 10000 µF (exact match required)
• Voltage Rating: 16 V (exact match required)
• Tolerance: ±20% (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Style: Radial, Can - Snap-In (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)
• Can Diameter: 0.866" (22.00mm) (exact match required)
• Polarization: Polar (exact match required)
• RoHS Compliance: ROHS3 Compliant (required for regulatory alignment)

Allowed Variation Parameters:

• Height - Seated (Max): Variation permitted within mechanical envelope constraints
• ESR (Equivalent Series Resistance): Variation permitted; lower ESR indicates performance enhancement
• Lifetime @ Temperature: Variation permitted; extended lifetime indicates performance enhancement
• Operating Temperature Range: Variation permitted; extended upper temperature limit indicates performance enhancement
• Ripple Current Ratings: Variation permitted; higher ripple current indicates performance enhancement

Substitutes are classified as Direct Equivalent or Upgrade based on performance characteristics while maintaining full electrical and mechanical compatibility.

Engineering Selection Recommendations

Direct Equivalent: SLPX103M016A3P3

The SLPX103M016A3P3 maintains full electrical and mechanical compatibility with the 109LBA016M2BD. Both parts share identical capacitance, voltage rating, tolerance, lead spacing, can diameter, and mounting configuration. The SLPX103M016A3P3 demonstrates performance enhancement through reduced ESR (66 mOhm versus 82.89 mOhm) and extended lifetime rating (3000 Hrs @ 85°C versus 2000 Hrs @ 85°C). Both parts are Active status, RoHS3 compliant, and REACH unaffected. The SLPX103M016A3P3 features a reduced seated height of 1.181" (30.00mm) compared to 1.260" (32.00mm), providing improved mechanical fit in space-constrained applications. Selection of this substitute is appropriate for direct replacement in existing designs.

Upgrade Option: B41252A4109M000

The B41252A4109M000 manufactured by EPCOS - TDK Electronics provides an upgrade path while maintaining full electrical and mechanical compatibility. This part matches all critical parameters: 10000 µF capacitance, 16 V rating, ±20% tolerance, through-hole mounting, radial snap-in package, 0.394" lead spacing, and 0.866" can diameter. The B41252A4109M000 extends the operating temperature range to -40°C ~ 105°C and provides 2000 Hrs lifetime at the elevated 105°C temperature, compared to 85°C for the main part. This upgrade is suitable for applications requiring enhanced thermal performance or extended operating temperature margins. Both parts are Active status, RoHS3 compliant, and REACH unaffected.

Frequently Asked Questions (FAQ)

Q: Can SLPX103M016A3P3 be used as a direct replacement for 109LBA016M2BD?

A: Yes. The SLPX103M016A3P3 is a direct equivalent. All critical electrical parameters (10000 µF, 16 V, ±20% tolerance) and mechanical parameters (through-hole, radial snap-in, 0.394" lead spacing, 0.866" can diameter) are identical. The reduced seated height of 1.181" (30.00mm) versus 1.260" (32.00mm) provides improved fit in space-constrained PCB layouts. Both parts are RoHS3 compliant and Active status.

Q: What is the difference between the Direct Equivalent and Upgrade options?

A: The SLPX103M016A3P3 (Direct Equivalent) provides performance enhancement through lower ESR and extended lifetime at 85°C while maintaining identical operating temperature range. The B41252A4109M000 (Upgrade) extends the maximum operating temperature to 105°C and provides lifetime rating at this elevated temperature, suitable for high-temperature applications. Both maintain full electrical and mechanical compatibility.

Q: Does the reduced height of SLPX103M016A3P3 affect compatibility?

A: No. The SLPX103M016A3P3 seated height of 1.181" (30.00mm) is lower than the main part's 1.260" (32.00mm). This reduction improves mechanical fit in applications with height constraints. The part remains fully compatible with standard through-hole PCB layouts designed for the original 109LBA016M2BD.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. Both SLPX103M016A3P3 and B41252A4109M000 are RoHS3 compliant and REACH unaffected, matching the regulatory status of the 109LBA016M2BD.

Q: Can B41252A4109M000 be used in applications requiring 85°C operation?

A: Yes. The B41252A4109M000 operating temperature range is -40°C ~ 105°C, which encompasses the -40°C ~ 85°C range of the main part. This upgrade is suitable for any application using the 109LBA016M2BD and provides additional thermal margin for high-temperature environments.

Q: What is the inventory status of substitute parts?

A: SLPX103M016A3P3 has 1190 Pcs in stock. B41252A4109M000 has 1518 Pcs in stock. Both are available as new original parts.
