Engineering Selection Recommendations
Primary Equivalent Selection:
For direct replacement with identical electrical and mechanical specifications, select Fair-Rite Products Corp. 2508053017Y0 or Cal-Chip Electronics FB201209T-301Y-S. Both parts maintain 300 Ohms impedance at 100 MHz, 300mA current rating, and 250mOhm DC resistance. The Fair-Rite part is available in higher inventory (64,808 pieces) and offers Tape & Reel packaging. The Cal-Chip part provides 104,737 pieces in stock with Tape & Reel format and RoHS compliance certification.
Enhanced Performance Selection:
For applications requiring improved current handling or reduced DC resistance, select Cal-Chip Electronics FB201209T-301Y-S-1 (500mA, 200mOhm) or Abracon LLC ACML-0805-301-T (500mA, 250mOhm). Both maintain 300 Ohms impedance and 0805 package compatibility. The Cal-Chip variant provides superior DC resistance performance (200mOhm versus 250mOhm) with 100,791 pieces available. The Abracon part offers 4,374 pieces in stock with slightly reduced height (1.05mm versus 1.10mm).
High Current Applications:
TDK Corporation MMZ2012S301AT000 supports 600mA current rating with 200mOhm DC resistance and 300 Ohms impedance. This part is designated Last Time Buy status with 2,000 pieces in inventory. Selection of this part requires acknowledgment of limited future availability.
Impedance Variance Consideration:
Cal-Chip Electronics FB201209T-331Y-S provides 330 Ohms impedance (10% higher than specified) with identical current and resistance ratings. This part is suitable only for applications where impedance tolerance permits the variance. Product status is Active with 21,028 pieces available.
Obsolete Part Avoidance:
KEMET Z0805C241ASMST and Z0805C241BSMST are designated Obsolete status with 240 Ohms impedance (20% lower than specified). These parts are not recommended for new designs despite adequate current and resistance specifications.
Frequently Asked Questions (FAQ)
Q: Can Fair-Rite Products Corp. 2508053017Y0 be used as a direct replacement for TE Connectivity 2176486-4?
A: Yes. Both parts share identical impedance (300 Ohms @ 100 MHz), current rating (300mA), DC resistance (250mOhm), package (0805), and operating temperature range (-55°C ~ 125°C). The primary difference is packaging format: the original part is Cut Tape while the Fair-Rite equivalent is Tape & Reel. Both are ROHS3 compliant and Active status.
Q: What is the difference between FB201209T-301Y-S and FB201209T-301Y-S-1?
A: Both Cal-Chip parts maintain 300 Ohms impedance and 0805 package compatibility. The FB201209T-301Y-S-1 variant provides enhanced performance with 500mA current rating (versus 300mA) and 200mOhm DC resistance (versus 250mOhm). The base FB201209T-301Y-S matches the original part specifications exactly. Selection depends on whether the application requires the additional current margin and reduced resistance.
Q: Why is MMZ2012S301AT000 marked Last Time Buy?
A: TDK Corporation has discontinued this product line. The Last Time Buy designation indicates that existing inventory (2,000 pieces) represents the final available stock. New designs should not incorporate this part; existing designs should transition to active alternatives such as FB201209T-301Y-S-1 or ACML-0805-301-T.
Q: Can KEMET Z0805C241ASMST or Z0805C241BSMST be used as substitutes?
A: These parts are not recommended. Both are designated Obsolete status and provide 240 Ohms impedance, which is 20% lower than the specified 300 Ohms. While current rating (600mA) and DC resistance (200mOhm) exceed requirements, the impedance variance makes these parts unsuitable for EMI suppression applications requiring precise frequency response characteristics.
Q: What is the significance of packaging format differences (Cut Tape versus Tape & Reel)?
A: Packaging format affects assembly process compatibility and cost structure. Cut Tape (CT) format is suitable for manual assembly and small-volume production. Tape & Reel (TR) format is optimized for automated pick-and-place assembly in high-volume manufacturing. Electrical and mechanical performance are identical; selection depends on production methodology and volume requirements.
Q: Is Abracon LLC ACML-0805-301-T compatible with the original TE Connectivity part?
A: Yes, with one dimensional consideration. The Abracon part maintains 300 Ohms impedance, 0805 package, and -55°C ~ 125°C operating range. Maximum height is 1.05mm (versus 1.10mm for the original part), which provides additional PCB clearance. Current rating is enhanced to 500mA. This part is suitable for direct replacement in applications where the reduced height does not conflict with component placement constraints.
Q: What compliance certifications should be verified when selecting a substitute?
A: All recommended substitute parts maintain ROHS3 compliance and REACH Unaffected status, matching the original TE Connectivity part. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all Tape & Reel packaged alternatives, indicating no special moisture control requirements during storage or assembly. Verify that selected substitute meets your specific regulatory and environmental requirements before implementation.
