CLF6045T-150M-H Equivalent & Substitute Parts

Part Overview

The CLF6045T-150M-H is a 15 µH shielded drum core wirewound inductor manufactured by TDK Corporation, rated for 2 A continuous current with 55 mOhm DC resistance. This surface mount component is designed for applications requiring fixed inductance in compact form factors. The part is classified as "Not For New Designs," indicating it has been superseded in TDK's product portfolio. Identifying equivalent substitute parts is necessary for ongoing production support, legacy system maintenance, and design flexibility when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CLF6045T-150M-H must maintain electrical compatibility based on the following critical parameters:

• Inductance Value: Must be 15 µH (±20% tolerance acceptable)
• Current Rating: Minimum 2 A continuous current capability
• DC Resistance: Should not significantly exceed 55 mOhm to maintain thermal and efficiency characteristics
• Core Material & Shielding: Ferrite core with shielding required for electromagnetic compatibility
• Mounting & Package: Surface mount technology with compatible footprint dimensions
• Environmental Compliance: ROHS3 compliance and operating temperature range compatibility

The two identified substitutes—CLF6045NIT-150M-D and LGJ7045TC-150M-H—meet the core inductance and current specifications but present trade-offs in current rating, DC resistance, physical dimensions, and product status that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

CLF6045NIT-150M-D is the primary recommended substitute. It maintains active product status from TDK Corporation and carries AEC-Q200 automotive qualification. The part operates across an extended temperature range (-55°C to 150°C), providing broader environmental coverage than the original. The 1.7 A current rating is lower than the main part's 2 A specification; this substitute is suitable only for applications where the actual operating current does not exceed 1.7 A. The increased DC resistance of 72 mOhm (versus 55 mOhm) results in higher power dissipation and should be evaluated against thermal budget constraints. Physical dimensions are nearly identical (6.30mm × 6.00mm versus 6.20mm × 5.90mm), with a slightly increased height of 4.80mm. ROHS3 compliance is maintained.

LGJ7045TC-150M-H offers superior current handling (2.1 A) and lower DC resistance (51 mOhm), making it electrically favorable for high-current applications. However, this part is classified as Obsolete, limiting its availability and long-term supply reliability. The larger footprint (7.20mm × 6.90mm) may present layout constraints in space-critical designs. AEC-Q200 qualification is present. This substitute should be considered only when current capacity and resistance characteristics are critical and supply chain risk is acceptable.

For new production or long-term designs, CLF6045NIT-150M-D is the preferred path forward due to active status and compliance certifications. Applications with strict current requirements at or above 2 A should evaluate alternative inductor families rather than relying on these substitutes.

Frequently Asked Questions (FAQ)

Q: Can CLF6045NIT-150M-D directly replace CLF6045T-150M-H in all applications?

A: Direct replacement is possible only if the application's actual operating current does not exceed 1.7 A. The substitute has a lower current rating (1.7 A versus 2 A) and higher DC resistance (72 mOhm versus 55 mOhm). Thermal analysis is required to confirm acceptable power dissipation at the higher resistance value.

Q: What is the significance of the "Not For New Designs" status on the main part?

A: This designation indicates that TDK Corporation has discontinued active development and recommends against using this part in new designs. The CLF6045NIT-150M-D (Active status) is the manufacturer's recommended path forward for ongoing production.

Q: Why is LGJ7045TC-150M-H listed as a substitute if it is Obsolete?

A: The LGJ7045TC-150M-H is included for reference in legacy system maintenance scenarios where existing inventory may be available. Its Obsolete status means it is no longer manufactured and should not be selected for new production. Availability is limited to existing stock channels.

Q: Are there physical footprint compatibility concerns with these substitutes?

A: The CLF6045NIT-150M-D has nearly identical dimensions (6.30mm × 6.00mm versus 6.20mm × 5.90mm) and is footprint-compatible. The LGJ7045TC-150M-H is significantly larger (7.20mm × 6.90mm) and may not fit existing PCB layouts designed for the original part. Height differences (4.80mm and 4.50mm respectively) should be verified against clearance requirements.

Q: Do all three parts maintain RoHS3 compliance?

A: Yes. The main part CLF6045T-150M-H and both substitutes (CLF6045NIT-150M-D and LGJ7045TC-150M-H) are ROHS3 compliant. Environmental compliance is maintained across all options.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging is standard for automated assembly lines and provides continuous component supply on reels. Cut Tape (CT) & Digi-Reel® packaging offers smaller quantities and is suitable for lower-volume or prototype applications. The CLF6045NIT-150M-D uses Tape & Reel, while LGJ7045TC-150M-H uses Cut Tape & Digi-Reel®, affecting procurement and assembly process compatibility.

Q: What does AEC-Q200 qualification mean?

A: AEC-Q200 is an automotive industry standard qualification for passive components. Both substitutes carry this certification, indicating they meet stringent reliability and performance requirements for automotive applications. The main part does not list this rating.
