1008HC-152EJFS Surface Mount Wirewound Inductor Equivalent & Substitute Parts

Part Overview

The 1008HC-152EJFS is a 1.5 µH unshielded drum core wirewound inductor manufactured by Delta Electronics/Components, designed for surface mount applications in the 1008 (2520 Metric) package form factor. This component is classified as obsolete product status, necessitating identification of active equivalent and substitute parts for ongoing design requirements and procurement continuity.

The 1008HC-152EJFS operates across a temperature range of -40°C to 85°C with a rated current capacity of 550 mA and DC resistance of 450 mOhm. The inductor exhibits a self-resonant frequency of 182 MHz and quality factor of 25 at 7.96 MHz test frequency. Current inventory availability is 1007 pieces in new original condition.

Due to obsolete product status, equivalent parts from active manufacturers must be evaluated to maintain supply chain continuity and support ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1008HC-152EJFS is determined by strict adherence to the following critical parameters:

Primary Matching Criteria:

• Inductance value: 1.5 µH (exact match required)
• Package / Case: 1008 (2520 Metric) (exact match required)
• Core material: Ferrite (exact match required)
• Shielding configuration: Unshielded (exact match required)
• Mounting type: Surface Mount (exact match required)

Secondary Compatibility Parameters:

• Inductance tolerance: ±5% or tighter
• Operating temperature range: Minimum -40°C to 85°C coverage
• RoHS3 compliance status
• Moisture sensitivity level: 1 (Unlimited)

Application-Dependent Parameters:

• Current rating: Minimum 550 mA required for direct replacement
• DC resistance: Acceptable range determined by circuit requirements
• Self-resonant frequency: Minimum 182 MHz
• Quality factor: Application-specific requirement

Substitute parts are classified into two categories:

Direct Substitutes meet or exceed all primary and secondary criteria with current active product status, supporting seamless design replacement.

Similar Substitutes match all primary criteria but exhibit reduced current ratings or modified DC resistance characteristics, requiring circuit-level evaluation for application compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitute Selection:

The 744758315A (Würth Elektronik WE-RFH series) and AISC-1008F-1R5G-T (Abracon AISC-1008F series) are classified as direct substitutes for the 1008HC-152EJFS. Both components maintain active product status, ensuring long-term supply chain availability and manufacturing support.

744758315A (Würth Elektronik) provides current rating of 630 mA, exceeding the original 550 mA specification. DC resistance is specified at 750 mOhm maximum, representing a 67% increase from the original 450 mOhm value. This component maintains identical operating temperature range (-40°C to 85°C) and achieves higher self-resonant frequency of 250 MHz. ROHS3 compliance and MSL 1 rating confirm regulatory alignment.

AISC-1008F-1R5G-T (Abracon LLC) delivers current rating of 630 mA with DC resistance of 760 mOhm maximum. This substitute offers tighter inductance tolerance of ±2% compared to the original ±5% specification. Quality factor of 35 at 50 MHz indicates superior performance characteristics. Identical operating temperature range and full regulatory compliance support direct replacement capability.

Similar Substitute Evaluation:

The CW252016-1R5J (Bourns Inc.) and NLV25T-1R5J-EF (TDK Corporation) are classified as similar substitutes due to significantly reduced current ratings of 280 mA and 220 mA respectively, both substantially below the original 550 mA specification. These components exhibit substantially elevated DC resistance values (2.3 Ohm and 1.3 Ohm respectively) compared to the original 450 mOhm specification.

CW252016-1R5J supports extended operating temperature range to 125°C, providing thermal margin beyond original specifications. NLV25T-1R5J-EF operates to 105°C with REACH affected status, requiring compliance verification for specific applications.

Similar substitutes are suitable only for applications where current requirements do not exceed 280 mA and where elevated DC resistance is acceptable within circuit design parameters.

Compliance and Regulatory Status:

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols. The AISC-1008F-1R5G-T and 744758315A maintain REACH unaffected status identical to the original component. NLV25T-1R5J-EF carries REACH affected designation, requiring additional compliance documentation for certain applications.

Frequently Asked Questions (FAQ)

Q: Can 744758315A directly replace 1008HC-152EJFS in all applications?

A: The 744758315A meets all primary substitution criteria with active product status and current rating exceeding original specifications (630 mA vs. 550 mA). However, DC resistance increases from 450 mOhm to 750 mOhm maximum. Applications sensitive to DC resistance characteristics require circuit-level evaluation to confirm acceptable performance within design tolerances.

Q: What is the primary difference between direct and similar substitutes?

A: Direct substitutes (744758315A and AISC-1008F-1R5G-T) maintain current ratings at or above 550 mA, supporting applications requiring the original current capacity. Similar substitutes (CW252016-1R5J and NLV25T-1R5J-EF) provide current ratings of 280 mA and 220 mA respectively, limiting application scope to lower-current designs. All four parts maintain identical 1.5 µH inductance value and 1008 package form factor.

Q: How does inductance tolerance affect substitute selection?

A: The original 1008HC-152EJFS specifies ±5% inductance tolerance. AISC-1008F-1R5G-T offers tighter ±2% tolerance, providing superior inductance accuracy. Remaining substitutes maintain ±5% tolerance matching original specifications. Applications requiring specific inductance accuracy should prioritize AISC-1008F-1R5G-T for enhanced performance margin.

Q: Are all substitutes compatible with existing PCB layouts?

A: All substitute parts utilize identical 1008 (2520 Metric) package form factor and surface mount mounting type, ensuring PCB footprint compatibility. Physical dimensions vary slightly: 744758315A measures 0.102" L x 0.083" W (2.60mm x 2.10mm) with 0.075" maximum height; AISC-1008F-1R5G-T measures 0.115" L x 0.110" W (2.92mm x 2.79mm) with 0.090" maximum height. Verify PCB clearance specifications for height-constrained applications.

Q: What is the impact of increased DC resistance in substitute parts?

A: DC resistance increases from 450 mOhm (original) to 750 mOhm (744758315A) or 760 mOhm (AISC-1008F-1R5G-T) represent 67% and 69% increases respectively. In applications where inductor DC resistance contributes to circuit losses or voltage drop calculations, these increases require circuit analysis to confirm acceptable performance. Similar substitutes exhibit substantially higher DC resistance (1.3 to 2.3 Ohm), limiting application compatibility to designs tolerating elevated resistance values.

Q: Which substitute offers the best long-term supply availability?

A: AISC-1008F-1R5G-T (Abracon LLC) demonstrates highest inventory availability with 195,110 pieces in new original stock, providing superior supply chain security. 744758315A (Würth Elektronik) maintains 1,855 pieces in stock. Both components carry active product status with established manufacturing support, ensuring sustained availability for production requirements.

Q: Are there temperature range considerations for substitute selection?

A: Original 1008HC-152EJFS operates -40°C to 85°C. Direct substitutes 744758315A and AISC-1008F-1R5G-T maintain identical temperature range. CW252016-1R5J extends to 125°C, providing thermal margin for high-temperature applications. NLV25T-1R5J-EF operates to 105°C. Applications requiring operation beyond 85°C should select CW252016-1R5J or NLV25T-1R5J-EF, with current rating limitations noted.

Q: What packaging format differences exist between main part and substitutes?

A: Original 1008HC-152EJFS is supplied in bulk packaging. All substitute parts are supplied in Tape & Reel (TR) format, standard for automated assembly processes. TR packaging provides improved handling efficiency and component protection during manufacturing. No functional differences exist; packaging format selection depends on production volume and assembly equipment compatibility.
