Key Parameters

Substitute Part Grouping Explanation

Substitution of the LMK107BJ105MAHT is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Capacitance: 1 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Upgradeable Parameters:

• Voltage Rating: May be increased above 10V (higher voltage rating provides additional design margin)
• Temperature Coefficient: May be changed from X5R to X7R (different temperature stability characteristics)
• Operating Temperature Range: May be extended (X7R variants support -55°C ~ 125°C)

Substitute parts must maintain identical capacitance, tolerance, package dimensions, and compliance certifications. Voltage rating and temperature coefficient may differ to accommodate specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Same Electrical Characteristics): No direct equivalent exists with identical voltage rating and temperature coefficient. The LMK107BJ105MAHT is the only variant combining 10V rating with X5R temperature coefficient in this series.

Voltage-Rated Upgrades (Increased Design Margin):

• EMK107BJ105MAHT (16V, X5R): Provides 60% voltage margin increase while maintaining X5R temperature stability and -55°C ~ 85°C operating range. Highest inventory availability (332,627 pcs).
• TMK107BJ105MAHT (25V, X5R): Provides 150% voltage margin increase with X5R temperature stability. Suitable for applications requiring enhanced voltage headroom.
• GMK107BJ105MAHT (35V, X5R): Provides 250% voltage margin increase with X5R temperature stability and Ultra Low ESR features. Recommended for SMPS filtering applications.

Temperature Coefficient Variants (Extended Operating Range):

• LMK107B7105MAHT (10V, X7R): Maintains 10V rating while extending operating temperature range to -55°C ~ 125°C through X7R coefficient. Supports 40°C additional upper temperature operation.
• EMK107B7105MAHT (16V, X7R): Combines 16V rating with X7R temperature stability and extended -55°C ~ 125°C range.

All substitute parts maintain ROHS3 compliance, AEC-Q200 automotive qualification, MSL 1 rating, and 0603 package compatibility. Selection should be based on application voltage requirements and operating temperature specifications.

Frequently Asked Questions (FAQ)

Q: Can LMK107B7105MAHT replace LMK107BJ105MAHT in all applications?

A: LMK107B7105MAHT is electrically compatible as a direct substitute. Both parts share identical 1 µF capacitance, ±20% tolerance, 10V rating, and 0603 package. The difference is temperature coefficient: X7R (LMK107B7105MAHT) provides extended operating range to -55°C ~ 125°C compared to X5R (-55°C ~ 85°C). This substitution is valid when the extended temperature range does not conflict with application requirements.

Q: What is the difference between X5R and X7R temperature coefficients?

A: X5R and X7R are temperature coefficient classifications defining capacitance variation across operating temperature ranges. X5R specifies ±15% capacitance change over -55°C ~ 85°C. X7R specifies ±15% capacitance change over -55°C ~ 125°C. X7R variants support higher maximum operating temperatures. Selection depends on application thermal requirements.

Q: Can I use EMK107BJ105MAHT (16V) instead of LMK107BJ105MAHT (10V)?

A: Yes. EMK107BJ105MAHT is a valid substitute with increased voltage rating (16V vs. 10V). Higher voltage rating provides additional design margin and does not degrade performance in 10V applications. Both parts share identical capacitance (1 µF), tolerance (±20%), temperature coefficient (X5R), operating range (-55°C ~ 85°C), and 0603 package. EMK107BJ105MAHT has significantly higher inventory availability (332,627 pcs vs. 11,703 pcs).

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All listed substitute parts carry AEC-Q200 automotive qualification, matching the original LMK107BJ105MAHT specification. This certification is maintained across all voltage ratings and temperature coefficient variants.

Q: What is the physical compatibility of substitute parts?

A: All substitute parts use identical 0603 (1608 Metric) surface mount package with dimensions 0.063" L × 0.031" W (1.60mm × 0.80mm) and maximum thickness 0.035" (0.90mm). Physical footprint and PCB layout compatibility is guaranteed across all variants.

Q: Which substitute part has the best inventory availability?

A: EMK107BJ105MAHT (16V, X5R) has the highest inventory with 332,627 pcs in stock, compared to 11,703 pcs for the original LMK107BJ105MAHT. This part combines voltage upgrade with superior supply availability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental and regulatory certifications.
