1210HS-151EMFS Equivalent & Substitute Parts

Part Overview

The 1210HS-151EMFS is a 150 nH unshielded drum core wirewound inductor manufactured by Delta Electronics/Components, designed for surface mount applications in the 1210 (3225 Metric) package. This component operates at 650 mA with a DC resistance of 150 mOhm and is rated for -40°C to 85°C operating temperature range.

The 1210HS-151EMFS is classified as obsolete. Identification of equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this inductance value and package format.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1210HS-151EMFS is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 150 nH (exact match required)
• Inductance tolerance: ±20% (matching tolerance specification)
• Package format: 1210 (3225 Metric) surface mount
• Core type: Ferrite drum core, wirewound, unshielded
• Frequency test point: 25.2 MHz

Secondary Compatibility Criteria:

• Current rating: Must equal or exceed 650 mA minimum
• DC resistance: Must not exceed 150 mOhm maximum
• Operating temperature range: Must support -40°C to 85°C minimum
• Regulatory compliance: ROHS3 compliant, REACH unaffected

The substitute part NLCV32T-R15M-EFRD meets all primary matching criteria and exceeds secondary compatibility requirements through higher current rating (2.6 A) and lower DC resistance (28.8 mOhm max).

Parameter Comparison

Engineering Selection Recommendations

The NLCV32T-R15M-EFRD is a qualified substitute for the obsolete 1210HS-151EMFS based on the following engineering factors:

Functional Equivalence: Both components provide 150 nH inductance with ±20% tolerance in the 1210 (3225 Metric) surface mount package. Electrical performance at the 25.2 MHz test frequency is equivalent for the specified inductance value.

Product Status: The NLCV32T-R15M-EFRD maintains active product status with TDK Corporation, ensuring ongoing availability and supply chain support. The 1210HS-151EMFS obsolete status necessitates substitution for new designs and production continuity.

Regulatory Compliance: Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The NLCV32T-R15M-EFRD includes AEC-Q200 automotive qualification, providing additional reliability assurance.

Performance Margin: The substitute part provides superior electrical performance with 2.6 A current rating (versus 650 mA) and 28.8 mOhm maximum DC resistance (versus 150 mOhm), offering design margin for thermal and current stress conditions.

Physical Compatibility: Both components share identical maximum seated height (0.094" / 2.40mm). The substitute part has slightly smaller footprint dimensions (3.20mm x 2.50mm versus 3.50mm x 2.80mm), which is compatible with existing PCB layouts designed for the 1210 package.

Frequently Asked Questions (FAQ)

Q: Can NLCV32T-R15M-EFRD be used as a direct replacement for 1210HS-151EMFS in existing designs?

A: Yes. Both components provide identical 150 nH inductance with ±20% tolerance in the 1210 (3225 Metric) surface mount package. The substitute part meets or exceeds all electrical specifications of the original component. Physical compatibility is confirmed through matching maximum seated height and compatible package footprint.

Q: What are the key differences between these two inductors?

A: The primary differences are manufacturer (Delta Electronics versus TDK Corporation), product status (obsolete versus active), and electrical performance margins. The NLCV32T-R15M-EFRD provides higher current rating (2.6 A versus 650 mA) and lower DC resistance (28.8 mOhm max versus 150 mOhm). Operating temperature range extends to 125°C (versus 85°C). Q factor at 25.2 MHz is lower (10 versus 35), and self-resonant frequency is lower (500 MHz versus 600 MHz).

Q: Are there packaging differences between these parts?

A: The 1210HS-151EMFS is supplied in standard packaging format. The NLCV32T-R15M-EFRD is supplied in Tape & Reel (TR) format. Both use the 1210 (3225 Metric) surface mount package with identical maximum seated height. Footprint dimensions are slightly different but remain compatible with 1210 package PCB layouts.

Q: What compliance certifications apply to the substitute part?

A: The NLCV32T-R15M-EFRD is ROHS3 compliant, REACH unaffected, and AEC-Q200 qualified. These certifications meet automotive and industrial reliability standards. Both components carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Is the lower Q factor of the substitute part a concern?

A: Q factor difference (10 versus 35 at 25.2 MHz) reflects different core material characteristics between manufacturers. For 150 nH inductance applications, this difference does not affect functional equivalence. Application-specific performance validation should be conducted if Q factor is a critical design parameter.

Q: Can the substitute part handle the same current as the original?

A: The substitute part exceeds the original current rating. The NLCV32T-R15M-EFRD is rated for 2.6 A continuous current, compared to 650 mA for the 1210HS-151EMFS. This provides additional design margin and thermal performance in current-limited applications.
