TMK316B7105KLHT Equivalent & Substitute Parts

Part Overview

The TMK316B7105KLHT is a 1 µF ±10% 25V ceramic capacitor manufactured by Taiyo Yuden in X7R temperature coefficient with 1206 (3216 Metric) package configuration. This multilayer ceramic capacitor (MLCC) is designed for surface mount applications in automotive and SMPS filtering circuits. The part carries AEC-Q200 automotive qualification and ROHS3 compliance.

The TMK316B7105KLHT is designated as "Not For New Designs," indicating that Taiyo Yuden has discontinued active development for this specific model number. Equivalent substitute parts are available from both Taiyo Yuden's active product lines and alternative manufacturers that maintain identical electrical and mechanical specifications, ensuring direct functional replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TMK316B7105KLHT is determined by strict equivalence across the following parameters:

Electrical Parameters: Capacitance value (1 µF), tolerance (±10%), rated voltage (25V), and temperature coefficient (X7R) must be identical. The X7R temperature coefficient ensures capacitance stability across the -55°C to 125°C operating range with minimal variation, critical for automotive and filtering applications.

Mechanical Parameters: Package type (1206 / 3216 Metric), mounting method (Surface Mount, MLCC), physical dimensions (0.126" L x 0.063" W, 3.20mm x 1.60mm), and maximum thickness (0.071" / 1.80mm) must match exactly to ensure PCB footprint compatibility and assembly process compatibility.

Compliance & Certification: AEC-Q200 automotive qualification and ROHS3 compliance are required for automotive applications. Moisture Sensitivity Level 1 (Unlimited) indicates no special moisture handling requirements during storage or assembly.

All substitute parts listed maintain these parameters without deviation, enabling direct replacement in existing designs.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: MAAST31LSB7105KTNA01 and MCAST31LSB7105KTNA01 are recommended as primary selections. Both parts are designated as "Active" by Taiyo Yuden, ensuring long-term availability and continued manufacturing support. These parts maintain identical electrical and mechanical specifications to the TMK316B7105KLHT while offering active product status for design longevity.

For Existing Inventory Management: TMF316B7105KLHT provides a direct Taiyo Yuden equivalent with significantly higher inventory availability (570,968 pcs in stock). Although designated "Not For New Designs," this part is suitable for sustaining production of existing designs and offers immediate availability for replacement applications.

For Multi-Source Supply Chain: CL31B105KAPWPNE from Samsung Electro-Mechanics provides cross-manufacturer equivalence with identical electrical and mechanical parameters. This part is designated "Active" and carries AEC-Q200 automotive qualification, enabling supply chain diversification while maintaining full functional compatibility. The Open Mode feature does not affect electrical performance in standard filtering applications.

All substitute parts carry ROHS3 compliance and AEC-Q200 automotive qualification, ensuring regulatory and quality standards alignment with the original TMK316B7105KLHT specification.

Frequently Asked Questions (FAQ)

Q: Can TMF316B7105KLHT be used as a direct replacement for TMK316B7105KLHT?

A: Yes. TMF316B7105KLHT is a direct parametric equivalent with identical capacitance (1 µF), tolerance (±10%), voltage rating (25V), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), package (1206 / 3216 Metric), and all mechanical dimensions. Both are Taiyo Yuden products with AEC-Q200 qualification and ROHS3 compliance. The primary difference is product status; TMF316B7105KLHT is also "Not For New Designs" but offers substantially higher inventory availability.

Q: Are MAAST31LSB7105KTNA01 and MCAST31LSB7105KTNA01 suitable for automotive applications?

A: Yes. Both parts carry AEC-Q200 automotive qualification and are designated as "Active" products by Taiyo Yuden. They maintain identical electrical specifications (1 µF ±10% 25V X7R) and mechanical package (1206 / 3216 Metric) required for automotive circuit applications. Active product status ensures continued manufacturing support and long-term availability.

Q: Can CL31B105KAPWPNE from Samsung Electro-Mechanics replace the Taiyo Yuden TMK316B7105KLHT?

A: Yes. CL31B105KAPWPNE is a parametric equivalent from an alternative manufacturer with identical electrical parameters (1 µF ±10% 25V X7R), operating temperature range (-55°C ~ 125°C), package configuration (1206 / 3216 Metric), and all mechanical dimensions. It carries AEC-Q200 automotive qualification and ROHS3 compliance. The Open Mode feature indicates failure mode behavior and does not affect normal circuit operation.

Q: What does "Not For New Designs" status mean for the TMK316B7105KLHT?

A: "Not For New Designs" indicates that Taiyo Yuden has discontinued active development and marketing of this specific part number. The part remains available for existing designs and sustaining production but is not recommended for new circuit designs. Equivalent active alternatives (MAAST31LSB7105KTNA01, MCAST31LSB7105KTNA01) should be selected for new designs to ensure long-term supply continuity.

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

A: Yes. All substitute parts use the 1206 (3216 Metric) package with identical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm) and maximum thickness of 0.071" (1.80mm). They are all surface mount MLCCs with identical footprint requirements, enabling direct PCB compatibility without layout modifications.

Q: Do all substitute parts have the same moisture sensitivity requirements?

A: Yes. All parts listed carry Moisture Sensitivity Level (MSL) 1, classified as "Unlimited." This indicates no special moisture handling, storage, or baking requirements during manufacturing or assembly processes. Standard component handling procedures apply.

Q: What is the difference between the Taiyo Yuden series designations (M, MAAS, MCAS)?

A: Series designations indicate different product lines within Taiyo Yuden's ceramic capacitor portfolio. TMK316B and TMF316B belong to the "M" series (Not For New Designs), while MAAST31 and MCAST31 represent active product series with identical electrical and mechanical specifications. Series designation does not affect electrical performance or compatibility; it reflects manufacturing lineage and product lifecycle status.
