Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VLF12060T-331M1R0 must satisfy the following electrical and mechanical criteria:

• Inductance value of 330 µH with ±20% tolerance
• Shielded ferrite core construction
• Surface mount configuration
• Current rating of 1 A or greater
• DC resistance within acceptable limits for the application
• Compatible physical dimensions and mounting footprint
• Operating temperature range that encompasses or exceeds the original specification

The two substitute parts identified meet these core requirements while offering improvements in current handling capacity, compliance certifications, or supply availability.

Parameter Comparison

Engineering Selection Recommendations

CLF12577NIT-331M-D is suitable for applications requiring extended temperature operation up to 150°C and higher current capacity at 1.2 A. This part carries Last Time Buy status from TDK Corporation and includes AEC-Q200 automotive qualification. ROHS3 compliance is confirmed. The inductance test frequency matches the original specification at 100 kHz, ensuring consistent performance characterization.

CDRH127/LDNP-331MC is an active product from Sumida America Components Inc., providing long-term supply availability. This part supports 1.2 A current rating and maintains ROHS3 compliance. The operating temperature range of -40°C to 100°C covers the original specification minimum. The inductance test frequency of 1 kHz differs from the original 100 kHz specification.

Both substitutes exceed the original 1 A current rating, providing design margin. DC resistance values remain within acceptable proximity to the original specification. Physical dimensions differ slightly; mechanical fit verification is required for specific PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can CLF12577NIT-331M-D directly replace VLF12060T-331M1R0 in existing designs?

A: CLF12577NIT-331M-D meets all core electrical specifications: 330 µH inductance, ±20% tolerance, shielded ferrite core, and surface mount configuration. The higher current rating (1.2 A vs. 1 A) and extended temperature range (-55°C to 150°C) provide additional design margin. Physical dimensions differ (12.80mm x 12.50mm x 8.00mm vs. 12.00mm x 11.70mm x 6.00mm); PCB footprint compatibility must be verified.

Q: What are the key differences between the two substitute parts?

A: CLF12577NIT-331M-D is a TDK product with Last Time Buy status, AEC-Q200 qualification, and extended temperature range to 150°C. CDRH127/LDNP-331MC is an active Sumida product with long-term availability and standard automotive temperature range to 100°C. Both support 1.2 A current and maintain ±20% inductance tolerance. Inductance test frequencies differ: 100 kHz for CLF12577NIT-331M-D and 1 kHz for CDRH127/LDNP-331MC.

Q: Are there compliance or certification differences?

A: CLF12577NIT-331M-D includes AEC-Q200 automotive qualification and ROHS3 compliance. CDRH127/LDNP-331MC provides ROHS3 compliance. Both parts have MSL rating of 1 (Unlimited) and REACH Unaffected or Affected status as specified. Compliance requirements for your application should determine the appropriate selection.

Q: How do DC resistance values affect substitution?

A: The original VLF12060T-331M1R0 specifies 464 mOhm maximum DC resistance. CLF12577NIT-331M-D is rated at 492 mOhm maximum, and CDRH127/LDNP-331MC at 471 mOhm maximum. These variations remain within typical design tolerances for inductor applications. Power dissipation calculations should account for the specific DCR value of the selected substitute.

Q: What packaging formats are available for these substitutes?

A: CLF12577NIT-331M-D is supplied in Cut Tape (CT) packaging. CDRH127/LDNP-331MC is supplied in Tape & Reel (TR) packaging. Packaging selection depends on production volume and assembly process requirements.
