TMK316BJ106MLHT Equivalent & Substitute Parts

Part Overview

The TMK316BJ106MLHT is a 10 µF, 25V ceramic capacitor in 1206 (3216 Metric) package manufactured by Taiyo Yuden. This multilayer ceramic capacitor (MLCC) features X5R temperature coefficient and is rated for automotive and SMPS filtering applications with AEC-Q200 compliance. The part is designated as "Not For New Designs," indicating it has been superseded in the manufacturer's product line. Equivalent and substitute parts are necessary for ongoing production support, design flexibility, and inventory management.

Substitute Part Grouping Explanation

Substitution of the TMK316BJ106MLHT is determined by strict equivalence in the following parameters:

Critical Parameters for Direct Substitution:

Capacitance: 10 µF (exact match required)
Tolerance: ±20% (exact match required)
Temperature Coefficient: X5R (exact match required)
Package / Case: 1206 (3216 Metric) (exact match required)
Operating Temperature Range: -55°C ~ 85°C (exact match required)
Mounting Type: Surface Mount, MLCC (exact match required)

Allowable Variation:

Voltage Rating: Rated voltage may be equal to or higher than the original 25V specification. Higher voltage ratings provide additional design margin and are electrically compatible in circuits designed for 25V operation.

Compliance Requirements:

AEC-Q200 automotive rating
ROHS3 compliance
Moisture Sensitivity Level 1

Substitute parts are grouped into two categories: parametric equivalents (identical voltage rating) and upgrade substitutes (higher voltage rating with identical capacitance and all other electrical characteristics).

Engineering Selection Recommendations

Parametric Equivalents (25V Rating):

MCAST31LSB5106MTNA01 is the preferred parametric equivalent. This Taiyo Yuden part maintains identical electrical specifications to the TMK316BJ106MLHT while carrying Active product status. It is suitable for direct replacement in existing designs and new production runs where 25V rating is specified.

GRT31CR61E106ME01L is a Murata Electronics parametric equivalent with identical electrical characteristics. This part is designated as "Not For New Designs" but remains available for ongoing production support of existing designs.

Upgrade Substitute (35V Rating):

GMK316BBJ106MLHT is a Taiyo Yuden upgrade substitute with 35V voltage rating. The higher voltage rating provides additional design margin while maintaining all other electrical parameters. The maximum thickness increases from 0.071" to 0.075", which must be verified for PCB layout compatibility. This part is designated as "Not For New Designs."

Selection between parametric equivalents and upgrade substitutes depends on circuit voltage requirements and available PCB clearance. All substitute parts maintain AEC-Q200 compliance, ROHS3 compliance, and MSL 1 rating.

Frequently Asked Questions (FAQ)

Q: Can GMK316BBJ106MLHT (35V) be used in place of TMK316BJ106MLHT (25V)?

A: Yes. The 35V rated part is electrically compatible in circuits designed for 25V operation. Higher voltage ratings provide additional safety margin. However, the maximum thickness increases from 1.80mm to 1.90mm, requiring verification of PCB layout clearance.

Q: What is the difference between parametric equivalents and upgrade substitutes?

A: Parametric equivalents (MCAST31LSB5106MTNA01 and GRT31CR61E106ME01L) maintain identical voltage ratings of 25V. The upgrade substitute (GMK316BBJ106MLHT) provides a higher 35V rating with the same capacitance and all other electrical characteristics.

Q: Are all substitute parts suitable for automotive applications?

A: Yes. All substitute parts carry AEC-Q200 automotive qualification and are rated for automotive and SMPS filtering applications.

Q: Why is MCAST31LSB5106MTNA01 recommended over other parametric equivalents?

A: MCAST31LSB5106MTNA01 carries Active product status, indicating ongoing manufacturer support and availability. The other parametric equivalent (GRT31CR61E106ME01L) is designated "Not For New Designs."

Q: Are there any differences in moisture sensitivity or RoHS compliance?

A: No. All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity level and ROHS3 compliance, identical to the main part.

Q: Can these parts be used interchangeably on the same PCB?

A: MCAST31LSB5106MTNA01 and GRT31CR61E106ME01L are direct mechanical and electrical replacements. GMK316BBJ106MLHT requires PCB layout verification due to increased maximum thickness (1.90mm vs. 1.80mm).

Q: What certifications apply to all substitute parts?

A: All parts are AEC-Q200 rated, ROHS3 compliant, and carry REACH Unaffected status where applicable.
