ELC-09D100F Equivalent & Substitute Parts

Part Overview

The ELC-09D100F is a 10 µH unshielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 2.5 A continuous current with 27mOhm DC resistance. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The part is mounted through-hole in a radial, vertical cylinder package and is ROHS3 compliant.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELC-09D100F is based on the following critical parameters:

• Inductance Value: 10 µH (exact match required)
• Current Rating: 2.5 A minimum (equal or higher acceptable)
• DC Resistance: Must not exceed application tolerance limits
• Mounting Type: Through Hole (mechanical compatibility)
• Package Configuration: Radial, Vertical Cylinder (PCB footprint compatibility)
• Shielding: Unshielded (electromagnetic environment compatibility)

The RLB0912-100KL from Bourns Inc. meets these substitution criteria. Both parts share identical inductance values, current ratings, and mounting configurations. The substitute part is currently in active production status with improved availability compared to the obsolete ELC-09D100F.

Parameter Comparison

Engineering Selection Recommendations

The RLB0912-100KL is a direct functional substitute for the ELC-09D100F based on matching inductance, current rating, and mounting configuration. Both parts are ROHS3 compliant, meeting regulatory requirements for new designs.

The substitute part offers the advantage of active production status, ensuring long-term availability and supply chain stability. The RLB0912-100KL features tighter inductance tolerance (±10% versus ±20%), which may provide improved circuit performance in applications requiring closer inductance control.

Physical dimensions differ slightly: the substitute is smaller in diameter (0.343" versus 0.374") but taller (0.433" versus 0.350"). PCB layout verification is required to confirm clearance compatibility in existing designs.

DC resistance is higher in the substitute (43mOhm Max versus 27mOhm), which will result in increased power dissipation. Applications with strict thermal or efficiency requirements must evaluate this parameter against circuit specifications.

Frequently Asked Questions (FAQ)

Q: Can the RLB0912-100KL directly replace the ELC-09D100F on existing PCBs?

A: Functional substitution is possible due to matching inductance and current ratings. However, physical dimensions differ. The substitute is smaller in diameter but taller. PCB layout review is necessary to confirm that the height difference does not create clearance conflicts with adjacent components or board constraints.

Q: What is the impact of the higher DC resistance in the RLB0912-100KL?

A: The substitute has 43mOhm maximum DC resistance compared to 27mOhm in the original part. This results in approximately 59% higher resistive losses at rated current. For applications sensitive to power dissipation or thermal performance, circuit analysis is required to determine if this difference is acceptable within design margins.

Q: Are both parts suitable for the same operating temperature range?

A: The ELC-09D100F does not specify an operating temperature range in the provided data. The RLB0912-100KL operates from -40°C to 105°C. Temperature compatibility must be verified against application requirements.

Q: What is the difference in inductance tolerance between these parts?

A: The ELC-09D100F has ±20% tolerance, while the RLB0912-100KL has ±10% tolerance. The substitute provides tighter inductance control, which may improve circuit performance in applications where inductance variation affects frequency response or filtering characteristics.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant. The RLB0912-100KL includes REACH Unaffected status. Both carry EAR99 ECCN classification. No compliance barriers exist for substitution.
