Part Overview

The LDBAA2120JC5N0 is a 0.012 µF film capacitor manufactured by KEMET, rated for 16V DC operation with ±5% tolerance. This surface-mount component utilizes polyphenylene sulfide (PPS) metallized-stacked dielectric technology in a 1206 (3216 Metric) package form factor. The part is classified as Active product status with ROHS3 compliance and is suitable for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C.

Equivalent and substitute parts are identified to address inventory availability, extended voltage ratings, improved tolerance specifications, or alternative manufacturer sourcing while maintaining functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LDBAA2120JC5N0 is determined by the following critical parameters:

Primary Matching Criteria:

• Capacitance value: 0.012 µF (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Dielectric Material: Polyphenylene Sulfide (PPS), Metallized - Stacked (exact match required)
• Termination: Solder Pads (exact match required)

Secondary Compatibility Parameters:

• Voltage Rating - DC: Equal to or greater than 16V
• Tolerance: Equal to or tighter than ±5%
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

Substitute parts must satisfy all primary matching criteria. Secondary parameters may vary within the specified allowances, provided the substitute part maintains or exceeds the performance envelope of the original component.

Parameter Comparison

Engineering Selection Recommendations

LDBCA2120JC5N0 (KEMET): This substitute maintains identical physical dimensions, package specifications, and dielectric material to the primary part. The 50V DC voltage rating provides enhanced voltage margin over the 16V requirement. Both parts share ROHS3 compliance and identical MSL classification. Selection of this part is appropriate when higher voltage headroom is required or when KEMET series continuity is preferred.

ECH-U1C123GX5 (Panasonic Electronic Components): This substitute offers improved tolerance specification at ±2% compared to the ±5% tolerance of the primary part. The voltage rating matches at 16V DC. Physical dimensions are slightly reduced (3.20mm x 1.60mm versus 3.30mm x 1.70mm), and MSL classification is superior at Level 1 (Unlimited) versus Level 3. ROHS3 compliance is maintained. Selection of this part is appropriate when tighter capacitance tolerance is required and when reduced moisture sensitivity is beneficial.

ECH-U1C123JB5 (Panasonic Electronic Components): This substitute provides electrical equivalence with ±5% tolerance and 16V DC rating. Physical dimensions are slightly reduced, and MSL classification is Level 1. However, this part carries RoHS non-compliant status, which may restrict use in applications requiring regulatory compliance. Selection of this part is limited to applications where RoHS compliance is not mandated.

ECH-U1C123JX5 (Panasonic Electronic Components): This substitute matches the primary part in tolerance (±5%) and voltage rating (16V DC). Physical dimensions are slightly reduced (3.20mm x 1.60mm), and MSL classification is superior at Level 1. ROHS3 compliance is maintained. Selection of this part is appropriate when Panasonic sourcing is preferred and when reduced moisture sensitivity is beneficial.

Frequently Asked Questions (FAQ)

Q: Can LDBCA2120JC5N0 be used as a direct replacement for LDBAA2120JC5N0?

A: Yes. LDBCA2120JC5N0 is a direct substitute. Both parts share identical capacitance (0.012 µF), tolerance (±5%), package (1206), dielectric material (PPS metallized-stacked), and operating temperature range (-55°C ~ 125°C). The LDBCA2120JC5N0 provides a higher voltage rating (50V versus 16V), which is compatible with circuits designed for 16V operation. Both parts maintain ROHS3 compliance.

Q: What is the difference between ECH-U1C123GX5 and ECH-U1C123JX5?

A: Both Panasonic parts share identical electrical specifications (0.012 µF, ±5% tolerance, 16V DC rating) and package dimensions (3.20mm x 1.60mm). The primary difference is tolerance: ECH-U1C123GX5 offers ±2% tolerance compared to ±5% for ECH-U1C123JX5. Both parts feature MSL Level 1 classification and ROHS3 compliance. Selection depends on whether the tighter tolerance specification is required for the application.

Q: Are there physical compatibility concerns when substituting Panasonic parts for KEMET parts?

A: Panasonic ECH-U1 series parts have slightly reduced physical dimensions (3.20mm x 1.60mm) compared to KEMET LDB series parts (3.30mm x 1.70mm). Both maintain the same 1206 package designation and maximum seated height of 0.043" (1.10mm), with the exception of ECH-U1C123JB5 which has a maximum seated height of 0.039" (1.00mm). These dimensional variations are within standard 1206 package tolerances and do not prevent PCB-level substitution. Verification of PCB layout clearances is recommended for space-constrained designs.

Q: Why is ECH-U1C123JB5 marked as RoHS non-compliant?

A: ECH-U1C123JB5 carries RoHS non-compliant status, which indicates the part does not meet Restriction of Hazardous Substances (RoHS) regulatory requirements. This classification restricts use in applications or markets requiring RoHS compliance. Alternative parts LDBAA2120JC5N0, LDBCA2120JC5N0, ECH-U1C123GX5, and ECH-U1C123JX5 all maintain ROHS3 compliance and are suitable for regulated applications.

Q: What does MSL Level 3 versus MSL Level 1 mean for component handling?

A: Moisture Sensitivity Level (MSL) indicates the maximum time a component can be exposed to ambient conditions (typically 30°C, 85% relative humidity) before soldering. MSL Level 3 allows 168 hours of exposure, while MSL Level 1 allows unlimited exposure. LDBAA2120JC5N0 and LDBCA2120JC5N0 require stricter moisture control during storage and handling compared to Panasonic ECH-U1 series parts. Selection of MSL Level 1 parts reduces moisture-related handling requirements and associated costs.

Q: Can ECH-U1C123GX5 be used in place of LDBAA2120JC5N0 if tolerance is critical?

A: Yes. ECH-U1C123GX5 provides superior tolerance specification at ±2% compared to the ±5% tolerance of LDBAA2120JC5N0. All other electrical parameters match: 0.012 µF capacitance, 16V DC rating, PPS metallized-stacked dielectric, and -55°C ~ 125°C operating temperature. Physical dimensions are slightly reduced, and MSL classification is improved. This substitution is appropriate for applications requiring tighter capacitance tolerance control.

Q: Are all substitute parts available in Tape & Reel (TR) packaging?

A: Yes. All substitute parts listed (LDBCA2120JC5N0, ECH-U1C123GX5, ECH-U1C123JB5, and ECH-U1C123JX5) are available in Tape & Reel (TR) packaging, matching the packaging format of the primary part LDBAA2120JC5N0. This ensures compatibility with automated assembly processes.
