1008HS-683EJFS Equivalent & Substitute Parts

Part Overview

The 1008HS-683EJFS is a 68 µH unshielded drum core wirewound inductor manufactured by Delta Electronics/Components, designed for surface mount applications in the 1008 (2520 Metric) package. This component operates at 90 mA current rating with 9.5Ω DC resistance and is specified for operation across -40°C to 85°C. The part is classified as obsolete, necessitating identification of active equivalent components that maintain functional compatibility for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1008HS-683EJFS is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 68 µH (±5% tolerance)
• Package designation: 1008 (2520 Metric)
• Core material: Ferrite
• Shielding configuration: Unshielded
• Mounting technology: Surface Mount

Secondary Compatibility Factors:

• Current rating must equal or exceed 90 mA
• DC resistance must be within acceptable circuit design margins
• Operating temperature range must support application requirements
• Regulatory compliance (RoHS3, REACH status)

The substitute part NLV25T-680J-EF from TDK Corporation meets the primary matching criteria with identical inductance, package, core material, and shielding configuration. Differences in current rating (70 mA vs. 90 mA) and DC resistance (16.6Ω vs. 9.5Ω) represent trade-offs that require circuit-level evaluation.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement in Active Production:

The NLV25T-680J-EF from TDK Corporation is the identified equivalent for the obsolete 1008HS-683EJFS. Both components share identical inductance specifications, package geometry, and core material composition. The substitute part carries active product status with confirmed availability (5441 pcs in stock), ensuring supply chain continuity.

Compliance Considerations:

Both parts maintain ROHS3 compliance and MSL Level 1 (unlimited moisture sensitivity), supporting deployment in standard manufacturing environments without additional moisture control measures. The TDK substitute extends the operating temperature range to 105°C, providing enhanced thermal margin compared to the original 85°C maximum.

Circuit-Level Evaluation Required:

The increase in DC resistance from 9.5Ω to 16.6Ω maximum and reduction in current rating from 90 mA to 70 mA necessitate circuit analysis to confirm compatibility. Applications operating near the original 90 mA specification or with tight DC resistance budgets require detailed thermal and performance modeling before implementation.

Frequently Asked Questions (FAQ)

Q: Can the NLV25T-680J-EF directly replace the 1008HS-683EJFS in all applications?

A: Both components share identical inductance (68 µH), package (1008/2520 Metric), core material (ferrite), and shielding configuration. However, the substitute exhibits higher DC resistance (16.6Ω vs. 9.5Ω) and lower current rating (70 mA vs. 90 mA). Circuit-level verification is required for applications operating at or near the original 90 mA specification or with stringent DC resistance requirements.

Q: What are the physical dimension differences between these parts?

A: The 1008HS-683EJFS measures 0.115" L × 0.110" W × 0.083" H (2.92mm × 2.79mm × 2.10mm). The NLV25T-680J-EF measures 0.098" L × 0.079" W × 0.075" H (2.50mm × 2.00mm × 1.90mm). Both fit the 1008 (2520 Metric) package classification, though the TDK part is physically smaller.

Q: Are there temperature range implications for substitution?

A: The original part operates -40°C to 85°C. The substitute extends this to -40°C to 105°C, providing additional thermal headroom. Applications limited to the original 85°C maximum are fully supported by the substitute.

Q: What is the impact of the higher DC resistance on circuit performance?

A: The increase from 9.5Ω to 16.6Ω maximum DCR affects power dissipation and voltage drop across the inductor. At 70 mA (the substitute's current rating), dissipation increases from approximately 44.1 mW to 77.6 mW. Circuit designs must account for this additional power loss and thermal generation.

Q: Is the lower current rating (70 mA vs. 90 mA) a limiting factor?

A: The substitute's 70 mA rating is lower than the original 90 mA specification. Applications requiring sustained operation above 70 mA cannot use this substitute. Circuits operating below 70 mA are fully compatible.

Q: What packaging format is available for the substitute?

A: The NLV25T-680J-EF is supplied in Tape & Reel (TR) format, suitable for automated assembly processes. The original part packaging format was not specified in available documentation.

Q: Are both parts compliant with current regulatory standards?

A: Both components are ROHS3 compliant with MSL Level 1 rating. The TDK substitute is REACH Affected, while the original part is REACH Unaffected. Applications subject to REACH restrictions require confirmation of material composition compliance.
