ELC-09D100DF Equivalent & Substitute Parts

Part Overview

The ELC-09D100DF 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, repairs, and production continuity. The part is mounted through-hole in a radial, vertical cylinder package and complies with ROHS3 standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELC-09D100DF is determined by the following critical parameters:

• Inductance Value: 10 µH (exact match required)
• Current Rating: Minimum 2.5 A
• DC Resistance: Must not exceed application tolerance limits
• Mounting Type: Through Hole (radial, vertical cylinder configuration)
• Package Compatibility: Physical dimensions must fit existing PCB layouts
• Shielding: Unshielded configuration
• Compliance: ROHS3 certification required

The RLB0912-100KL from Bourns Inc. meets these substitution criteria with matching inductance, current rating, and mounting configuration. While DCR differs (43mOhm vs. 27mOhm), this remains within acceptable tolerance for equivalent functionality in most applications.

Parameter Comparison

Engineering Selection Recommendations

The RLB0912-100KL is the qualified substitute for the obsolete ELC-09D100DF based on the following factors:

• Product Status: The RLB0912-100KL is active and in production, ensuring long-term availability and supply chain continuity.
• Compliance: Both parts maintain ROHS3 compliance, meeting regulatory requirements for new designs.
• Electrical Equivalence: Matching inductance (10 µH) and current rating (2.5 A) ensure functional compatibility in circuit applications.
• Physical Compatibility: Both components use through-hole radial, vertical cylinder mounting. Physical dimensions are similar, though height differs by 0.083" (2.10mm). PCB layout verification is required for height-sensitive applications.
• DC Resistance Consideration: The RLB0912-100KL exhibits higher DCR (43mOhm vs. 27mOhm). Applications sensitive to resistive losses must evaluate thermal and efficiency impacts.

Frequently Asked Questions (FAQ)

Q: Can the RLB0912-100KL directly replace the ELC-09D100DF without PCB modifications?

A: Physical dimensions differ slightly. The RLB0912-100KL is 0.031" (0.80mm) smaller in diameter but 0.083" (2.10mm) taller. Verify clearance in height-constrained layouts. Radial through-hole mounting is identical, so hole spacing remains compatible.

Q: Does the higher DC resistance of the RLB0912-100KL affect circuit performance?

A: The RLB0912-100KL has 43mOhm DCR compared to 27mOhm for the ELC-09D100DF. This 16mOhm difference increases resistive losses and heat generation. Evaluate thermal performance in high-current or continuous-duty applications. For most general-purpose filtering and energy storage applications, this difference is acceptable.

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

A: The ELC-09D100DF does not specify an operating temperature range in the provided data. The RLB0912-100KL operates from -40°C to 105°C. Confirm the original design temperature requirements before substitution.

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

A: The ELC-09D100DF has ±20% tolerance, while the RLB0912-100KL has ±10% tolerance. The Bourns substitute offers tighter tolerance control, which may improve circuit performance in precision applications.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant. The RLB0912-100KL includes REACH Unaffected status, providing additional regulatory documentation. Both carry EAR99 ECCN classification.
