TMF107B7223KAHT Equivalent & Substitute Parts

Part Overview

The TMF107B7223KAHT is a 0.022 µF ceramic capacitor rated at 25V with X7R temperature coefficient in 0603 (1608 Metric) surface mount package. Manufactured by Taiyo Yuden, this component is designated as "Not For New Designs," indicating it has been superseded in the manufacturer's product line. The part carries AEC-Q200 automotive qualification and ROHS3 compliance. Due to its obsolescence status, identifying parametrically equivalent alternatives is necessary for ongoing production support, maintenance applications, and design continuity where this capacitor is currently deployed.

Critical Matching Parameters:

Capacitance: 0.022 µF (exact match required)
Tolerance: ±10% (exact match required)
Voltage Rating: 25V (exact match required)
Temperature Coefficient: X7R (exact match required)
Operating Temperature Range: -55°C ~ 125°C (exact match required)
Package / Case: 0603 (1608 Metric) (exact match required)
Mounting Type: Surface Mount, MLCC (exact match required)
Physical Dimensions: 0.063" L x 0.031" W; Thickness 0.035" max (exact match required)
Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Frequently Asked Questions (FAQ)

Q: Can TMF107B7223KAHT be directly replaced with any of the listed substitutes? A: Yes. All listed substitutes are parametrically equivalent across capacitance, voltage rating, temperature coefficient, operating temperature range, package dimensions, and compliance certifications. Direct board-level replacement is supported without circuit design changes.

Q: What is the difference between the Taiyo Yuden substitutes MAAST168SB7223KTNA01 and MCAST168SB7223KTNA01? A: Both parts are parametrically identical. The difference lies in series designation (MAAS vs. MCAS) and inventory availability (1000 Pcs vs. 712 Pcs). Both carry Active product status and are suitable for new production.

Q: Why is CGJ3E2X7R1E223K080AA listed as a substitute if it is Obsolete? A: CGJ3E2X7R1E223K080AA meets all electrical and mechanical equivalence criteria. However, its Obsolete status indicates it is no longer in active production. It should not be selected for new designs but may be considered for legacy system maintenance where existing inventory exists.

Q: What does "Open Mode" feature in Samsung parts indicate? A: Open Mode is a failure characteristic specification indicating the capacitor's behavior under fault conditions. This feature does not affect functional equivalence in normal operating conditions and does not impact substitution suitability.

Q: Does the soft termination feature in GCJ188R71E223KA01D affect compatibility? A: Soft termination is a manufacturing feature that reduces mechanical stress on component terminations during board flexing. It does not affect electrical performance or compatibility. This feature is beneficial for boardflex-sensitive applications but does not prevent substitution in standard applications.

Q: Are all substitutes suitable for automotive applications? A: Yes. All listed substitutes carry AEC-Q200 automotive qualification and are rated for automotive applications. The original TMF107B7223KAHT and all substitutes meet automotive reliability and qualification standards.

Q: What is the significance of REACH Unaffected status on some parts? A: REACH Unaffected status indicates the part is not subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulatory requirements. This is a compliance designation that does not affect electrical or mechanical equivalence.

Q: Can substitutes be mixed in the same production batch? A: Yes. All substitutes are parametrically equivalent and carry identical electrical specifications, voltage ratings, temperature coefficients, and package dimensions. Mixed sourcing is supported from a functional standpoint, though single-source procurement is typically preferred for supply chain consistency.

Q: Which substitute offers the best long-term availability? A: MAAST168SB7223KTNA01 (Taiyo Yuden) maintains manufacturer consistency with the original part and carries Active status. GCJ188R71E223KA01D (Murata Electronics) offers the highest current inventory (6778 Pcs) and Active status, supporting extended production runs.
