CIS10P260AC Ferrite Bead 26 OHM 0603 Equivalent & Substitute Parts

Part Overview

The CIS10P260AC is a power line ferrite bead manufactured by Samsung Electro-Mechanics, designed for EMI suppression in single-line applications. This component operates at 26 Ohms impedance at 100 MHz with a maximum current rating of 6A and DC resistance of 7mOhm in a 0603 (1608 Metric) surface mount package. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. Ferrite beads in this specification are commonly used in power distribution circuits, signal integrity applications, and noise filtering in consumer electronics, industrial equipment, and telecommunications devices.

Substitute Part Grouping Explanation

Substitute parts for the CIS10P260AC are classified into two categories based on electrical parameter alignment:

Direct Electrical Equivalents (Identical Parameters): Parts that match all critical electrical specifications—26 Ohms impedance at 100 MHz, 6A maximum current rating, and 7mOhm DC resistance—are classified as direct equivalents. These parts maintain identical functional performance in the circuit and can be substituted without design modification. This group includes BLM18KG260TN1D (Murata Electronics), BBUP00160805260Y00 (Pulse Electronics), FBU160808T-260Y-S (Cal-Chip Electronics), MHC1608P260Z06BP6A0DG (INPAQ Technology), MPZ1608S260ATAH0 (TDK Corporation), UCB04-260-RC (Allied Components International), and BLM18SG260TN1D (Murata Electronics).

Parametric Equivalents (Acceptable Variations): Parts that deviate from one or more electrical parameters but remain functionally acceptable within system design tolerances are classified as parametric equivalents. These parts may have different impedance values, current ratings, or DC resistance specifications. Substitution requires circuit-level analysis to confirm compatibility. This group includes BLM18SN220TN1D (22 Ohms impedance, 8A current rating, 4mOhm DCR) and 7426926222 (22 Ohms impedance, 7.5A current rating, 4mOhm DCR), as well as BBUP00160805300Y00 (30 Ohms impedance, 6A current rating, 7mOhm DCR).

Substitution Logic: All substitute parts maintain the 0603 (1608 Metric) package footprint, surface mount mounting type, single power line configuration, and operating temperature range of -55°C to 125°C. All parts are RoHS3 compliant with MSL rating of 1 (Unlimited). Mechanical dimensions vary slightly across manufacturers but remain compatible with standard 0603 PCB layouts.

Engineering Selection Recommendations

For Direct Replacement (No Circuit Modification Required):

Select from parts with identical electrical specifications: BLM18KG260TN1D, BLM18SG260TN1D, BBUP00160805260Y00, FBU160808T-260Y-S, MHC1608P260Z06BP6A0DG, MPZ1608S260ATAH0, or UCB04-260-RC. All maintain 26 Ohms impedance at 100 MHz, 6A current rating, and 7mOhm DC resistance. All substitute parts are in active production status, ensuring long-term availability and supply chain stability. All parts are RoHS3 compliant and carry MSL rating of 1 (Unlimited), meeting environmental and moisture sensitivity requirements equivalent to the original CIS10P260AC.

For Parametric Substitution (Circuit Analysis Required):

BLM18SN220TN1D offers lower impedance (22 Ohms) with higher current capacity (8A) and lower DC resistance (4mOhm). This part is suitable for applications where reduced impedance and improved thermal performance are acceptable or beneficial. 7426926222 (Würth Elektronik WE-TMSB series) provides similar parametric characteristics with 22 Ohms impedance and 7.5A current rating. BBUP00160805300Y00 offers higher impedance (30 Ohms) at the same current and resistance ratings, suitable for applications requiring increased attenuation.

Packaging and Supply Considerations:

Murata Electronics BLM18 series parts (BLM18KG260TN1D, BLM18SG260TN1D, BLM18SN220TN1D) offer the highest inventory availability and established supply chain presence. TDK Corporation MPZ1608S260ATAH0 provides active production status with substantial stock levels. Pulse Electronics BBUP series parts offer multiple impedance options within the same package family. All parts support standard surface mount assembly processes compatible with 0603 footprints.

Frequently Asked Questions (FAQ)

Q: Can BLM18SG260TN1D be used as a direct replacement for CIS10P260AC?

A: Yes. BLM18SG260TN1D matches all critical electrical parameters: 26 Ohms impedance at 100 MHz, 6A maximum current rating, and 7mOhm DC resistance. The part is in active production status and RoHS3 compliant. The only difference is reduced height (0.026" versus 0.037"), which is mechanically compatible with standard 0603 PCB layouts.

Q: What is the difference between direct equivalents and parametric equivalents?

A: Direct equivalents (such as BLM18KG260TN1D, BBUP00160805260Y00, MPZ1608S260ATAH0) maintain identical impedance, current rating, and DC resistance specifications. Parametric equivalents (such as BLM18SN220TN1D with 22 Ohms impedance or BBUP00160805300Y00 with 30 Ohms impedance) have different electrical characteristics and require circuit-level analysis to confirm compatibility before substitution.

Q: Are all substitute parts RoHS3 compliant?

A: All listed substitute parts are RoHS3 compliant. FBU160808T-260Y-S and UCB04-260-RC carry RoHS Compliant certification. All parts meet REACH requirements and carry MSL rating of 1 (Unlimited), ensuring compatibility with standard manufacturing and storage conditions.

Q: What is the impact of height variation among substitute parts?

A: Height variations (ranging from 0.026" to 0.039") do not affect electrical performance or PCB footprint compatibility for 0603 packages. Height differences may impact solder joint formation and thermal dissipation characteristics. Parts with lower profile (0.026" to 0.030") offer improved thermal performance; parts with higher profile (0.039") may provide enhanced mechanical stability in high-vibration environments.

Q: Can BLM18SN220TN1D replace CIS10P260AC in all applications?

A: BLM18SN220TN1D has lower impedance (22 Ohms versus 26 Ohms), higher current capacity (8A versus 6A), and lower DC resistance (4mOhm versus 7mOhm). Substitution is acceptable in applications where reduced impedance and improved current handling are compatible with circuit design. Applications requiring specific 26 Ohms impedance filtering should use direct electrical equivalents.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in Cut Tape (CT) & Digi-Reel® packaging (Murata, TDK), Tape & Reel (TR) packaging (Würth Elektronik, Pulse Electronics, Cal-Chip, Allied Components), and Strip packaging (INPAQ). Selection depends on production volume requirements and assembly line compatibility.

Q: Is inventory availability a consideration for part selection?

A: Yes. Murata Electronics BLM18SG260TN1D offers the highest inventory level (849,975 pcs), followed by Pulse Electronics BBUP00160805260Y00 (60,493 pcs) and TDK Corporation MPZ1608S260ATAH0 (37,300 pcs). For long-term production programs, parts with higher inventory and active production status provide supply chain security.
