1008-103J Fixed Inductor Equivalent & Substitute Parts

Part Overview

The 1008-103J is a fixed surface mount inductor manufactured by API Delevan Inc. in the 1008 series. This component is a 10 µH unshielded ferrite core inductor rated for 245 mA with a maximum DC resistance of 2.5 Ohm, designed for nonstandard package applications. The part maintains Active product status with 1089 pieces currently in stock.

Substitute parts become necessary when original inventory is depleted, when design revisions require improved compliance certifications, or when supply chain optimization requires alternative qualified sources from the same manufacturer.

Substitute Part Grouping Explanation

Substitution eligibility for the 1008-103J is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications in the following critical areas:

Electrical Parameters (Must Match Exactly):

• Inductance value: 10 µH
• Inductance tolerance: ±5%
• Current rating: 245 mA
• DC resistance: 2.5 Ohm maximum
• Q factor at 7.9 MHz: 30
• Self resonant frequency: 28 MHz
• Core material: Ferrite
• Shielding configuration: Unshielded

Mechanical Parameters (Must Match Exactly):

• Mounting type: Surface Mount
• Package dimensions: 0.105" L × 0.095" W (2.66mm × 2.41mm)
• Height seated maximum: 0.095" (2.41mm)
• Packaging format: Tape & Reel (TR)

Environmental Parameters (Must Match Exactly):

• Operating temperature range: -55°C to 125°C
• Moisture sensitivity level: 1 (Unlimited)

The 1008R-103J qualifies as a direct substitute because it maintains complete parameter equivalence across all electrical, mechanical, and environmental specifications while originating from the same manufacturer series.

Engineering Selection Recommendations

1008-103J Selection Criteria: The 1008-103J remains the primary choice when RoHS non-compliant components are acceptable within the application's regulatory framework. This part carries Active product status with established inventory of 1089 pieces.

1008R-103J Selection Criteria: The 1008R-103J serves as the preferred substitute when ROHS3 compliance is required. This variant maintains complete electrical and mechanical equivalence while providing enhanced regulatory compliance certification. The 1008R-103J carries Active product status with higher available inventory of 1700 pieces, supporting extended production runs and supply chain continuity.

Both parts are manufactured by API Delevan Inc. and are suitable for direct substitution in surface mount applications requiring 10 µH inductance at 245 mA current rating with 2.5 Ohm maximum DC resistance. Selection between these parts depends solely on compliance requirements and inventory availability for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the 1008R-103J replace the 1008-103J in existing designs?

A: Yes. The 1008R-103J is a direct electrical and mechanical equivalent. All critical parameters including inductance, current rating, DC resistance, frequency response, package dimensions, and operating temperature range are identical. The primary difference is ROHS3 compliance certification on the 1008R-103J variant.

Q: What is the difference between the 1008 and 1008R series designations?

A: Both series are manufactured by API Delevan Inc. and share identical electrical and mechanical specifications for this inductance value. The "R" designation in the 1008R series indicates ROHS3 compliance certification. The series designation does not affect functional performance or physical compatibility.

Q: Are the package dimensions identical between both parts?

A: Yes. Both the 1008-103J and 1008R-103J share identical nonstandard package dimensions of 0.105" L × 0.095" W (2.66mm × 2.41mm) with a maximum seated height of 0.095" (2.41mm). Both are supplied in Tape & Reel (TR) packaging format for surface mount assembly.

Q: What determines substitution eligibility for this inductor?

A: Substitution eligibility is determined by exact equivalence across inductance value (10 µH ±5%), current rating (245 mA), DC resistance (2.5 Ohm maximum), core material (ferrite), shielding configuration (unshielded), frequency response characteristics (Q=30 @ 7.9 MHz, SRF=28 MHz), operating temperature range (-55°C to 125°C), and physical package dimensions. Any deviation in these parameters disqualifies a part from direct substitution.

Q: Which part should be selected for new designs?

A: For new designs, the 1008R-103J is recommended when regulatory compliance with ROHS3 standards is required. Both parts are Active status components suitable for production use. The 1008R-103J provides higher inventory availability (1700 pieces) compared to the 1008-103J (1089 pieces), supporting extended production schedules.

Q: Are there any performance differences between these parts?

A: No. Both parts deliver identical electrical performance. The Q factor at 7.9 MHz is 30 for both variants. The self resonant frequency is 28 MHz for both. DC resistance is 2.5 Ohm maximum for both. Current rating is 245 mA for both. All frequency-dependent and load-dependent characteristics are equivalent.
