CIS10P181AC Equivalent & Substitute Parts

Part Overview

The CIS10P181AC is a power line ferrite bead manufactured by Samsung Electro-Mechanics, designed for electromagnetic interference (EMI) suppression in single-line applications. This component operates at 180 Ohms impedance at 100 MHz with a maximum current rating of 2.5A and is packaged in the 0603 (1608 Metric) surface mount form factor.

The CIS10P181AC has reached obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this ferrite bead specification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CIS10P181AC are identified based on strict parametric equivalence within the allowed tolerance range for power line ferrite beads. The substitution logic is based on the following critical parameters:

Mechanical Compatibility:

• Package / Case: 0603 (1608 Metric) — identical form factor required for PCB footprint compatibility
• Mounting Type: Surface Mount — consistent with original design
• Height (Max): 0.037" (0.95mm) — ensures clearance and assembly compatibility

Electrical Compatibility:

• Filter Type: Power Line — same functional application category
• Number of Lines: 1 — single-line configuration maintained
• Operating Temperature Range: -55°C ~ 125°C — identical thermal operating window
• DC Resistance (DCR) (Max): 40mOhm — maximum allowable resistance maintained

Impedance Tolerance: The CIS10P181AC specifies 180 Ohms @ 100 MHz. Substitute parts with impedance values of 150 Ohms @ 100 MHz fall within the acceptable parametric range for power line ferrite bead applications, as impedance variation within this range does not compromise EMI suppression functionality in typical circuit designs.

Current Rating: Substitute parts with current ratings equal to or greater than 2.5A maintain thermal and electrical performance requirements.

Compliance & Environmental:

• RoHS Status: ROHS3 Compliant or RoHS Compliant — regulatory equivalence
• Moisture Sensitivity Level (MSL): 1 (Unlimited) — identical handling requirements
• REACH Status: REACH Unaffected — environmental compliance maintained

Engineering Selection Recommendations

FBH160808T-151Y-S (Cal-Chip Electronics, Inc.)

This substitute part is classified as a parametric equivalent with active product status. The FBH160808T-151Y-S maintains identical mechanical compatibility, thermal operating range, and compliance certifications. The impedance specification of 150 Ohms @ 100 MHz represents a 16.7% reduction from the original 180 Ohms specification. The current rating of 3A exceeds the original 2.5A requirement, providing additional thermal margin. This part is available in Tape & Reel packaging with substantial inventory availability (40,982 pieces), supporting high-volume production requirements.

HFZ 1608PF-151T25 (TAI-TECH Advanced Electronics Co., Ltd.)

This substitute part is classified as a parametric equivalent with active product status. The HFZ 1608PF-151T25 maintains identical mechanical compatibility, thermal operating range, and compliance certifications. The impedance specification of 150 Ohms @ 100 MHz represents a 16.7% reduction from the original 180 Ohms specification. The current rating of 2.5A matches the original specification exactly. This part is available in Tape & Reel packaging with inventory availability of 8,697 pieces.

Both substitute parts satisfy the core substitution criteria: identical package form factor, surface mount compatibility, single-line power line filter configuration, matching thermal operating range, and equivalent environmental compliance status. Selection between these two substitutes should be based on procurement availability, cost considerations, and specific application current requirements.

Frequently Asked Questions (FAQ)

Q: Can the FBH160808T-151Y-S or HFZ 1608PF-151T25 be used as direct replacements for the CIS10P181AC?

A: Both parts are parametric equivalents suitable for substitution in power line ferrite bead applications. They share identical package dimensions (0603 / 1608 Metric), mounting type (surface mount), thermal operating range (-55°C ~ 125°C), and compliance certifications. The impedance difference (150 Ohms versus 180 Ohms) falls within acceptable tolerance for power line EMI suppression applications.

Q: What is the significance of the impedance difference between 180 Ohms and 150 Ohms?

A: The impedance specification determines the ferrite bead's attenuation characteristics at 100 MHz. The 150 Ohm impedance of the substitute parts represents a 16.7% reduction from the original 180 Ohm specification. This difference is within the parametric tolerance range for power line ferrite bead applications and does not compromise EMI suppression functionality in typical circuit designs.

Q: Are there any differences in current handling capability?

A: The FBH160808T-151Y-S is rated for 3A maximum current, exceeding the original 2.5A specification. The HFZ 1608PF-151T25 is rated for 2.5A, matching the original specification exactly. Both parts maintain the same 40mOhm maximum DC resistance. Current rating selection should be based on specific application requirements.

Q: Do the substitute parts have the same packaging format?

A: The substitute parts are supplied in Tape & Reel (TR) packaging, while the original CIS10P181AC is listed as bulk packaging. Both formats are compatible with standard surface mount assembly processes. Tape & Reel packaging is standard for high-volume production environments.

Q: Are the substitute parts RoHS compliant?

A: Yes. The FBH160808T-151Y-S and HFZ 1608PF-151T25 are both RoHS Compliant. The original CIS10P181AC is ROHS3 Compliant. All three parts meet current regulatory requirements for hazardous substance restrictions.

Q: What is the Moisture Sensitivity Level (MSL) for the substitute parts?

A: Both substitute parts have MSL 1 (Unlimited), identical to the original CIS10P181AC. This classification indicates unlimited shelf life under normal storage conditions without special moisture control requirements.

Q: Are there any REACH or environmental compliance concerns with these substitutes?

A: No. Both substitute parts have REACH Unaffected status, matching the original part. All three components meet current environmental compliance requirements.

Q: Which substitute part should be selected for new designs?

A: Selection between FBH160808T-151Y-S and HFZ 1608PF-151T25 should be based on procurement availability, cost, and application-specific current requirements. The FBH160808T-151Y-S offers higher current capacity (3A) and greater inventory availability. The HFZ 1608PF-151T25 matches the original current specification (2.5A) exactly.
