Key Parameters

Substitute Part Grouping Explanation

Substitution of the LT02ZD105MAT2S is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters (Must Match):

• Capacitance: 1 µF
• Package / Case: 0402 (1005 Metric)
• Mounting Type: Surface Mount, MLCC
• Temperature Coefficient: X5R (baseline requirement)

Allowable Variations:

• Tolerance: ±20% (baseline) to ±10% (upgrade)
• Voltage - Rated: 10V (baseline) to 16V or 25V (upgrades)
• Temperature Coefficient: X5R (baseline) to X6S (extended range, -55°C ~ 105°C)
• Thickness: 0.022" (0.56mm) baseline; 0.013" (0.33mm) acceptable
• Packaging: Tape & Reel (TR) or Cut Tape (CT) acceptable

Substitute parts are categorized as direct equivalents (matching all baseline parameters), upgrades (improved tolerance or voltage rating), or manufacturer-recommended alternatives (enhanced temperature coefficient).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Active Status):

• KGM05AR51A105MH (KYOCERA AVX): Identical electrical specifications with active product status and Tape & Reel packaging. Preferred for new production due to manufacturer continuity and availability.
• C0402C105M8PAC7867 (KEMET): Matches all baseline parameters with active status. Suitable for applications requiring cross-manufacturer qualification.

Tolerance Upgrade (±10%):

• CGB2A1X5R1A105K033BC (TDK Corporation): Improved tolerance specification while maintaining 10V rating and X5R temperature coefficient. Applicable where tighter capacitance tolerance is required.

Voltage Rating Upgrade:

• CGB2A1X5R1C105K033BC (TDK Corporation): 16V rated with ±10% tolerance. Provides voltage margin for circuits operating near 10V nominal.
• CGB2A1X5R1E105K033BC (TDK Corporation): 25V rated with ±10% tolerance. Maximum voltage headroom within X5R series.

Temperature Coefficient Upgrade:

• CGB2A1X6S1A105K033BC (TDK Corporation): X6S coefficient extends operating range to -55°C ~ 105°C with ±10% tolerance. Suitable for high-temperature applications.
• CGB2A1X6S1A105M033BC (TDK Corporation): X6S coefficient with ±20% tolerance and extended temperature range.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and 0402 package footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can KGM05AR51A105MH directly replace LT02ZD105MAT2S in production? A: Yes. KGM05AR51A105MH is a direct electrical equivalent with identical capacitance (1 µF), tolerance (±20%), voltage rating (10V), and temperature coefficient (X5R). The primary difference is active product status and Tape & Reel packaging format.

Q: What is the difference between X5R and X6S temperature coefficients? A: X5R specifies capacitance change of ±15% across -55°C ~ 85°C operating range. X6S specifies ±15% change across -55°C ~ 105°C, extending the upper temperature limit by 20°C. X6S parts are suitable for applications requiring higher temperature operation.

Q: Are TDK CGB series parts compatible with the original KYOCERA AVX footprint? A: Yes. All substitute parts maintain 0402 (1005 Metric) package dimensions and Surface Mount MLCC mounting type. Physical footprint compatibility is confirmed. Note that TDK CGB parts feature reduced thickness (0.013" vs 0.022"), which is acceptable for standard PCB assembly.

Q: Can I use a 16V or 25V rated part in place of the 10V specification? A: Yes. Higher voltage-rated capacitors are electrically compatible in circuits designed for 10V operation. CGB2A1X5R1C105K033BC (16V) and CGB2A1X5R1E105K033BC (25V) provide voltage margin without affecting circuit function. Verify PCB layout accommodates the reduced thickness (0.013" vs 0.022").

Q: What packaging formats are available? A: LT02ZD105MAT2S is supplied in bulk. Direct equivalent KGM05AR51A105MH and KEMET C0402C105M8PAC7867 are available in Tape & Reel format. TDK CGB series parts are supplied in Cut Tape format. Confirm packaging compatibility with assembly equipment specifications.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental certifications.
