Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1008HC-102EJFS is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 1 µH (exact match required)
• Package / Case: 1008 (2520 Metric) (exact match required)
• Core material: Ferrite (exact match required)
• Shielding: Unshielded (exact match required)
• Mounting type: Surface Mount (exact match required)

Secondary Compatibility Parameters:

• Current rating: Substitute must equal or exceed 800 mA
• DC resistance: Substitute must be equal to or lower than 350 mOhm
• Operating temperature range: Substitute must cover or exceed -40°C ~ 85°C
• Tolerance: ±5% or tighter acceptable
• RoHS3 compliance required

All four substitute parts meet the primary matching criteria. Secondary parameter variations are documented in the comparison table below.

Parameter Comparison

Engineering Selection Recommendations

NLCV25T-1R0M-EFR (TDK Corporation)

This substitute provides the highest current rating (1 A) among available options, exceeding the original 800 mA specification. The DC resistance of 168 mOhm is significantly lower than the original 350 mOhm, resulting in reduced power dissipation. Operating temperature range extends to 105°C, covering the original -40°C ~ 85°C requirement. Product status is active with full RoHS3 compliance and MSL 1 rating. This part is suitable for applications where current headroom and thermal performance are design priorities.

CW252016-1R0J (Bourns Inc.)

This substitute offers extended operating temperature range (-40°C ~ 125°C) and active product status. Current rating is 330 mA, which is below the original 800 mA specification. DC resistance is 1.75 Ohm Max, significantly higher than the original 350 mOhm. This part is suitable only for applications where current requirements do not exceed 330 mA and where higher DC resistance is acceptable.

PM1008-1R0K-RC (Bourns Inc.)

This substitute is electrically identical to CW252016-1R0J with the same current rating (330 mA), DC resistance (1.75 Ohm), and extended operating temperature range (-40°C ~ 125°C). Product status is active with full RoHS3 compliance. Tolerance is ±10%. This part is suitable only for applications where current requirements do not exceed 330 mA.

NLV25T-1R0J-EFD (TDK Corporation)

This substitute has the lowest current rating (245 mA) among all options and is below the original 800 mA specification. DC resistance is 1.1 Ohm Max. Operating temperature range extends to 105°C. Product status is active with RoHS3 compliance. REACH status is listed as affected. This part is suitable only for low-current applications not exceeding 245 mA.

Frequently Asked Questions (FAQ)

Q: Can CW252016-1R0J or PM1008-1R0K-RC be used as direct replacements for 1008HC-102EJFS?

A: These parts share identical inductance (1 µH), package (1008), core type (ferrite), and shielding (unshielded). However, current rating is reduced to 330 mA versus the original 800 mA, and DC resistance increases to 1.75 Ohm versus 350 mOhm. These substitutes are compatible only in applications where current does not exceed 330 mA and where higher DC resistance is acceptable.

Q: Is NLCV25T-1R0M-EFR suitable for all applications using 1008HC-102EJFS?

A: NLCV25T-1R0M-EFR meets or exceeds all primary electrical parameters of the original part. Current rating is 1 A (exceeding 800 mA), DC resistance is 168 mOhm (lower than 350 mOhm), and operating temperature range extends to 105°C. This part is compatible with applications designed for 1008HC-102EJFS. Inductance tolerance is ±20% versus the original ±5%, which may require verification in tolerance-critical circuits.

Q: What is the difference between CW252016-1R0J and PM1008-1R0K-RC?

A: Both parts are manufactured by Bourns Inc. and share identical electrical specifications: 1 µH inductance, 330 mA current rating, 1.75 Ohm DC resistance, and -40°C ~ 125°C operating temperature. The primary difference is inductance tolerance: CW252016-1R0J is ±5% while PM1008-1R0K-RC is ±10%. Both are packaged in 1008 (2520 Metric) form factor with Tape & Reel packaging.

Q: Why does NLV25T-1R0J-EFD have lower current rating than other substitutes?

A: NLV25T-1R0J-EFD is rated for 245 mA continuous current, which is the lowest among all substitute options. This part is designed for lower-current applications. DC resistance is 1.1 Ohm Max. This part is not suitable for applications requiring the original 800 mA current rating.

Q: Are all substitute parts RoHS3 compliant?

A: All four substitute parts are RoHS3 compliant. All maintain MSL 1 (Unlimited) moisture sensitivity level, matching the original part specification.

Q: What packaging format is available for substitute parts?

A: All substitute parts are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The original 1008HC-102EJFS was supplied in bulk packaging.
