1210HS-183EKFS Equivalent & Substitute Parts Reference

Part Overview

The 1210HS-183EKFS is a fixed unshielded drum core wirewound inductor manufactured by Delta Electronics/Components, rated at 18 µH inductance with 165 mA current capacity and 2.5 Ohm DC resistance in a 1210 (3225 Metric) surface mount package. This component is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility within specified electrical and mechanical parameters. Substitute parts must preserve the 18 µH inductance value, 1210 package form factor, and ferrite core construction while accommodating variations in current rating, DC resistance, and operating temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1210HS-183EKFS is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• Inductance value: 18 µH (exact match required)
• Package designation: 1210 (3225 Metric) surface mount
• Core material: Ferrite unshielded drum core construction
• Mounting technology: Surface mount compatible

Allowable Variation Parameters:

• Current rating: Substitute must equal or exceed 165 mA minimum
• DC resistance: Substitute values lower than 2.5 Ohm are acceptable (reduced power loss)
• Operating temperature range: Substitute must cover or exceed -40°C ~ 85°C minimum
• Tolerance: ±10% tolerance maintained across substitutes
• RoHS/REACH compliance: ROHS3 Compliant status required

The substitute part 744032180 (Würth Elektronik WE-LQ series) satisfies all critical parameters while providing improved electrical performance through lower DC resistance (1.1 Ohm) and higher current rating (240 mA), with extended operating temperature range (-40°C ~ 125°C).

Parameter Comparison

Engineering Selection Recommendations

The 744032180 (Würth Elektronik WE-LQ series) is a qualified substitute for the obsolete 1210HS-183EKFS based on the following engineering criteria:

Compliance and Regulatory Status: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and production environments.

Product Lifecycle Consideration: The 1210HS-183EKFS is classified as obsolete, creating supply chain risk. The 744032180 is actively manufactured by Würth Elektronik with confirmed inventory availability (4088 pieces in stock), ensuring long-term procurement viability.

Electrical Parameter Alignment: The substitute part maintains identical inductance (18 µH) and tolerance (±10%), with improved electrical performance through reduced DC resistance (1.1 Ohm versus 2.5 Ohm) and higher current rating (240 mA versus 165 mA). These improvements reduce power dissipation and thermal stress in circuit operation.

Thermal Operating Range: The substitute extends the operating temperature range to -40°C ~ 125°C, exceeding the original specification of -40°C ~ 85°C. This provides enhanced reliability in elevated temperature environments.

Physical and Mechanical Compatibility: Both components utilize identical 1210 (3225 Metric) surface mount packaging with ferrite unshielded drum core construction, ensuring direct PCB footprint compatibility and assembly process compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 744032180 be used as a direct replacement for the 1210HS-183EKFS without circuit modification?

A: Yes. The 744032180 maintains identical inductance value (18 µH), tolerance (±10%), package form factor (1210), and core construction (ferrite unshielded drum core). Physical footprint and electrical characteristics are compatible with the original design. No circuit modification is required.

Q: What are the advantages of substituting to the 744032180?

A: The substitute provides three measurable improvements: reduced DC resistance (1.1 Ohm versus 2.5 Ohm) decreases power dissipation by 56%, higher current rating (240 mA versus 165 mA) provides 45% additional current capacity margin, and extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 85°C) supports higher ambient temperature applications.

Q: Are there any electrical performance differences between the two parts?

A: Both parts maintain the same inductance and tolerance specifications. The substitute exhibits different Q factor characteristics (35 @ 1MHz versus 25 @ 2.52MHz) and self-resonant frequency (15MHz versus 27MHz) due to different core materials and winding configurations. These differences do not affect substitution compatibility for standard filtering and energy storage applications.

Q: Does the substitute part meet the same regulatory and compliance standards?

A: Yes. The 744032180 is ROHS3 compliant and REACH unaffected, matching the regulatory status of the original 1210HS-183EKFS. Both components satisfy current environmental and hazardous substance restrictions.

Q: What is the packaging format for the substitute part?

A: The 744032180 is supplied in Tape & Reel (TR) format, standard for high-volume surface mount assembly. The original 1210HS-183EKFS packaging format is not specified in the provided data. Verify packaging compatibility with your assembly process requirements.

Q: Is the substitute part actively available for procurement?

A: Yes. The 744032180 is classified as active product status with confirmed inventory of 4088 pieces in stock, ensuring reliable long-term availability. The original 1210HS-183EKFS is obsolete, creating supply chain discontinuity.

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

A: The substitute exceeds the original current specification. The 744032180 is rated for 240 mA continuous current versus 165 mA for the 1210HS-183EKFS, providing 45% additional current capacity. Saturation current for the substitute is specified at 650 mA.
