Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LGJ7045TC-680M-H is determined by the following critical parameters:

• Inductance value: 68 µH with ±20% tolerance
• Core type and shielding: Ferrite, shielded drum core construction
• Mounting configuration: Surface mount, nonstandard package
• Current handling capability: Minimum 950 mA rating
• DC resistance: Maximum 210mOhm
• Thermal performance: Operating range of -40°C to 125°C minimum
• Compliance: AEC-Q200 qualification and ROHS3 compliance

The CLF7045NIT-680M-D meets all substitution criteria with improved electrical performance characteristics and active product status.

Parameter Comparison

Engineering Selection Recommendations

The CLF7045NIT-680M-D is the direct substitute for the obsolete LGJ7045TC-680M-H. Both components are manufactured by TDK Corporation and maintain identical inductance specifications with equivalent tolerance ratings. The substitute part provides enhanced current handling capability (1.08 A versus 950 mA) and improved DC resistance performance (200mOhm Max versus 210mOhm), while maintaining the same ferrite shielded drum core construction and surface mount configuration.

The CLF7045NIT-680M-D carries active product status, ensuring long-term availability and supply chain continuity. Both parts satisfy AEC-Q200 automotive qualification requirements and ROHS3 compliance mandates. The substitute part extends the operating temperature range to -55°C ~ 150°C, providing broader thermal performance margins compared to the original specification of -40°C ~ 125°C.

Physical dimensions show minor increases in length, width, and height for the substitute part, requiring verification of PCB layout compatibility within the target application. Both components maintain MSL Level 1 moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can CLF7045NIT-680M-D directly replace LGJ7045TC-680M-H in existing designs?

A: Yes, the CLF7045NIT-680M-D is a direct substitute. Both parts maintain 68 µH inductance with ±20% tolerance, identical core material and shielding configuration, and equivalent surface mount nonstandard packaging. PCB layout verification is required due to minor dimensional differences (approximately 0.008" increase in length and width, 0.012" increase in height).

Q: What are the key electrical differences between these parts?

A: The substitute part provides improved electrical performance with 1.08 A current rating versus 950 mA, and 200mOhm maximum DC resistance versus 210mOhm. Both parts maintain saturation current specifications within acceptable operating margins for the 68 µH inductance value.

Q: Are both parts AEC-Q200 qualified?

A: Yes, both the LGJ7045TC-680M-H and CLF7045NIT-680M-D carry AEC-Q200 automotive qualification ratings, meeting automotive industry reliability and performance standards.

Q: What is the impact of the extended temperature range on the substitute part?

A: The CLF7045NIT-680M-D operates from -55°C to 150°C compared to the original -40°C to 125°C range. This extended specification provides additional thermal margin for applications requiring broader operating conditions, with no negative impact on designs operating within the original temperature window.

Q: Are there any compliance or regulatory differences?

A: Both parts are ROHS3 compliant and maintain MSL Level 1 moisture sensitivity classification. The substitute part includes REACH Unaffected status. No compliance barriers exist for substitution.
