Substitute Part Grouping Explanation

Substitution of the ELC-09D332F is determined by the following critical parameters:

• Inductance Value: 3.3 mH (±10% tolerance acceptable)
• Current Rating: Minimum 140 mA required
• DC Resistance: Maximum 7Ohm acceptable
• Mounting Type: Through Hole required
• Package Configuration: Radial, Vertical Cylinder required
• Shielding: Unshielded configuration
• Compliance: ROHS3 Compliant

The substitute part RL895-332K-RC meets all critical substitution criteria within the allowed parameter ranges for this product category.

Parameter Comparison

Engineering Selection Recommendations

The RL895-332K-RC from Bourns Inc. is a direct functional equivalent for the obsolete ELC-09D332F. Both components are ROHS3 compliant and meet the electrical requirements for 3.3 mH inductance applications at 140 mA operation. The Bourns substitute provides superior current rating (150 mA versus 140 mA) and lower DC resistance (6.16Ohm Max versus 7Ohm), resulting in improved thermal performance. The active product status of the RL895-332K-RC ensures long-term availability and supply chain continuity compared to the obsolete Panasonic part.

Physical dimensions differ slightly: the RL895-332K-RC has a smaller diameter (0.307" versus 0.374") but slightly greater height (0.374" versus 0.350"). PCB layout verification is required to confirm mechanical fit within the application.

Frequently Asked Questions (FAQ)

Q: Can the RL895-332K-RC directly replace the ELC-09D332F without circuit modification?

A: Yes, the RL895-332K-RC meets all critical electrical parameters: identical 3.3 mH inductance, ±10% tolerance, and exceeds the 140 mA current requirement. DC resistance is lower (6.16Ohm Max versus 7Ohm), which is beneficial for thermal performance. PCB layout verification is necessary due to dimensional differences.

Q: What are the key dimensional differences between these parts?

A: The RL895-332K-RC has a smaller diameter (0.307" versus 0.374") but is slightly taller (0.374" versus 0.350"). Verify that the substitute fits within the available PCB space and component clearance envelope of your application.

Q: Are both parts RoHS compliant?

A: Yes, both the ELC-09D332F and RL895-332K-RC are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing.

Q: Why is the ELC-09D332F classified as obsolete?

A: The ELC-09D332F is no longer in active production by Panasonic Electronic Components. The RL895-332K-RC from Bourns Inc. is an active product with confirmed ongoing availability and supply chain support.

Q: What is the difference between wirewound and drum core construction?

A: The ELC-09D332F uses standard wirewound construction, while the RL895-332K-RC uses drum core wirewound construction with ferrite material. Both are unshielded configurations suitable for the same application class. Drum core design provides improved Q factor (45 @ 252kHz) and defined self-resonant frequency (700kHz).

Q: Are there any operating temperature considerations?

A: The RL895-332K-RC specifies operating temperature range of -30°C to 100°C. Verify this range is compatible with your application requirements.
