Part Overview

The TPME157M016H0030 is a 150µF molded tantalum capacitor rated at 16V with an ESR of 30mOhm @ 100kHz, manufactured by KYOCERA AVX in the TPM series. This component is designed for general-purpose applications requiring surface-mount tantalum capacitors in the 2917 (7343 Metric) package. The part is currently active in production with 1039 units in stock. Equivalent and substitute parts may be required due to inventory availability, manufacturing lead times, or specific compliance requirements for end applications.

Substitute Part Grouping Explanation

Substitution eligibility for the TPME157M016H0030 is determined by the following critical parameters: capacitance value (150µF), voltage rating (16V), package type (2917/7343 Metric), and mounting configuration (surface mount). All substitute parts must maintain these core electrical and mechanical specifications to ensure form, fit, and function compatibility.

Secondary parameters that may vary between the main part and substitutes include tolerance (±20% or ±10%), ESR characteristics (ranging from 30mOhm to 150mOhm @ 100kHz), and RoHS compliance status. These variations are acceptable within the substitution framework provided they do not compromise circuit performance or regulatory requirements for the end application.

Engineering Selection Recommendations

All listed substitute parts maintain active production status and are electrically and mechanically compatible with the TPME157M016H0030 based on matching capacitance, voltage rating, and package specifications.

For applications requiring RoHS3 compliance, TPSE157K016R0050V, T495D157M016ATE150, T495X157M016ATE100, and T510X157K016ATE030 are suitable alternatives, as the main part is RoHS non-compliant.

For applications with moisture-sensitive assembly processes, T495D157M016ATE150, T495X157M016ATE100, and T510X157K016ATE030 offer MSL 1 (Unlimited) ratings compared to the main part's MSL 3 (168 Hours).

T510X157K016ATE030 provides the highest inventory availability (363,300 units) with matching ESR characteristics (30mOhm @ 100kHz) and improved moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can TPSE157K016R0050V be used as a direct replacement for TPME157M016H0030?

A: Yes. Both parts share identical capacitance (150µF), voltage rating (16V), package type (2917/7343 Metric), and operating temperature range. The primary differences are tolerance (±10% vs ±20%) and ESR (50mOhm vs 30mOhm @ 100kHz). TPSE157K016R0050V also provides RoHS3 compliance.

Q: What is the significance of ESR differences among these parts?

A: ESR (Equivalent Series Resistance) affects ripple current handling and thermal performance. Lower ESR values (30mOhm) provide better high-frequency performance. Parts with higher ESR (100mOhm or 150mOhm) may be suitable for lower-frequency applications but should be evaluated for specific circuit requirements.

Q: Why does T495D157M016ATE150 have a lower seated height?

A: T495D157M016ATE150 has a maximum seated height of 0.122" (3.10mm) compared to 0.169" (4.30mm) for other parts. This dimensional difference must be considered for PCB layout and clearance requirements, particularly in space-constrained applications.

Q: Are all substitute parts available in the same packaging format?

A: TPME157M016H0030, TPSE157K016R0050V, T495D157M016ATE150, and T495X157M016ATE100 are supplied in Tape & Reel (TR) packaging. T510X157K016ATE030 is available in Cut Tape (CT) & Digi-Reel® format. Packaging selection should align with assembly process requirements.

Q: What is the impact of tolerance differences on circuit design?

A: The main part and most substitutes carry ±20% tolerance. TPSE157K016R0050V and T510X157K016ATE030 offer ±10% tolerance, providing tighter capacitance control. For applications sensitive to capacitance variation, the ±10% tolerance parts may be preferred.
