ECJ-MFF1A226Z Equivalent & Substitute Parts

Part Overview

The ECJ-MFF1A226Z is a 22 µF ceramic capacitor rated at 10V with Y5V temperature coefficient in 1206 surface mount package manufactured by Panasonic Electronic Components. This part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The part serves general-purpose capacitive functions in surface mount applications requiring stable capacitance across the -30°C to 85°C operating temperature range.

Substitute Part Grouping Explanation

Substitution for the ECJ-MFF1A226Z is determined by the following critical parameters: capacitance value (22 µF), tolerance range (-20%, +80%), temperature coefficient (Y5V), package type (1206), and mounting method (surface mount MLCC). Voltage rating and physical dimensions are secondary considerations that may vary within acceptable limits for the application.

Substitute parts are grouped into three categories:

Direct Equivalents maintain identical electrical specifications (10V rating, 22 µF, Y5V coefficient) with different manufacturers. These parts are interchangeable without circuit redesign.

Upgrade Substitute provides higher voltage rating (16V) while maintaining all other electrical parameters. This part is suitable for applications where increased voltage margin is acceptable or beneficial.

Similar Substitute matches all electrical specifications but may have minor dimensional variations within the 1206 package tolerance.

Engineering Selection Recommendations

Direct Equivalents (C1206C226Z8VAC7800, CC1206ZKY5V6BB226, KGM31AV51A226ZU) are suitable for one-to-one replacement of the obsolete ECJ-MFF1A226Z. All three parts are active products with RoHS3 compliance and REACH unaffected status. KEMET C1206C226Z8VAC7800 offers the highest inventory availability (7470 pcs). YAGEO CC1206ZKY5V6BB226 provides 4100 pcs in stock. KYOCERA AVX KGM31AV51A226ZU is available with 861 pcs.

Upgrade Substitute (CC1206ZKY5V7BB226) from YAGEO provides 16V rating instead of 10V while maintaining identical capacitance and tolerance. This part is suitable for applications where higher voltage margin is required or where circuit design permits voltage rating increase. This part has the highest inventory availability at 30400 pcs and is an active product with full compliance certifications.

All substitute parts maintain the same 1206 package footprint, surface mount mounting type, and Y5V temperature coefficient. Thickness variations (0.049" to 0.075") are within standard 1206 package tolerances and do not affect PCB assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use CC1206ZKY5V7BB226 (16V) as a direct replacement for ECJ-MFF1A226Z (10V)?

A: Yes. The 16V rated part is electrically compatible and physically identical in footprint. Higher voltage rating provides additional safety margin and does not degrade circuit performance in 10V applications.

Q: Are there dimensional differences between substitute parts?

A: Thickness varies from 0.049" (original) to 0.075" (upgrade). All parts conform to 1206 package specifications. Verify PCB clearance if height-constrained applications exist, though standard 1206 assembly processes accommodate this range.

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

A: Yes. All parts listed maintain MSL 1 (Unlimited), matching the original part's moisture handling requirements.

Q: Which substitute offers the best availability?

A: CC1206ZKY5V7BB226 (YAGEO, 16V upgrade) has 30400 pcs in stock. For direct 10V equivalents, C1206C226Z8VAC7800 (KEMET) offers 7470 pcs.

Q: Are all substitutes RoHS and REACH compliant?

A: All active substitute parts are RoHS3 compliant and REACH unaffected. The original Panasonic part status is obsolete and compliance information is not provided.
