ELL-5PR4R7N Equivalent & Substitute Parts

Part Overview

The ELL-5PR4R7N is a 4.7 µH shielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 1.8 A continuous current with 56 mOhm DC resistance. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The part operates at 100 kHz test frequency and is housed in a nonstandard 5.00mm x 5.00mm surface mount package with 2.00mm maximum seated height.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ELL-5PR4R7N is determined by strict equivalence across the following critical parameters:

• Inductance Value: 4.7 µH (fixed requirement)
• Inductance Tolerance: ±30% or tighter
• Current Rating: Minimum 1.8 A continuous
• Saturation Current: Minimum 2.2 A
• DC Resistance: Maximum 60 mOhm (allowing minor increase from 56 mOhm baseline)
• Shielding: Shielded construction required
• Mounting: Surface mount, 5.00mm x 5.00mm footprint
• Package Height: Maximum 2.00mm seated height
• Test Frequency: 100 kHz

Two substitute parts meet these criteria: LMLP05B5N4R7CTAR (KYOCERA AVX) and TYS50204R7M-10 (Laird-Signal Integrity Products). Both maintain the 4.7 µH inductance specification, support the required current levels, and fit the identical physical footprint.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturing support, addressing the obsolescence of the ELL-5PR4R7N. Selection between LMLP05B5N4R7CTAR and TYS50204R7M-10 depends on application-specific requirements:

LMLP05B5N4R7CTAR provides a direct current rating match (2 A vs. 1.8 A requirement) with ferrite core construction and ROHS3 compliance. DC resistance of 60 mOhm represents a 7% increase from the original specification.

TYS50204R7M-10 offers superior current headroom (2.2 A rating, 2.5 A saturation) with tighter inductance tolerance (±20% vs. ±30%) and lower DC resistance (57 mOhm max). This part includes specified self-resonant frequency (37 MHz) and ROHS3 compliance.

Both parts maintain identical physical footprints, MSL ratings, and test frequencies. Both are available in tape and reel packaging for automated assembly.

Frequently Asked Questions (FAQ)

Q: Can ELL-5PR4R7N be directly replaced with LMLP05B5N4R7CTAR or TYS50204R7M-10?

A: Yes. Both substitute parts maintain the 4.7 µH inductance value, support the required 1.8 A continuous current, and fit the identical 5.00mm x 5.00mm x 2.00mm footprint. No PCB layout modifications are required.

Q: What is the difference in DC resistance between the main part and substitutes?

A: The ELL-5PR4R7N specifies 56 mOhm. LMLP05B5N4R7CTAR is rated at 60 mOhm (4 mOhm higher), and TYS50204R7M-10 is rated at 57 mOhm maximum (1 mOhm higher). These differences are within typical component tolerances for this inductance class.

Q: Which substitute offers better performance headroom?

A: TYS50204R7M-10 provides higher current rating (2.2 A vs. 1.8 A), higher saturation current (2.5 A vs. 2.2 A), and tighter inductance tolerance (±20% vs. ±30%). LMLP05B5N4R7CTAR offers a more conservative upgrade with 2 A rating and ferrite core construction.

Q: Are both substitutes RoHS compliant?

A: Yes. Both LMLP05B5N4R7CTAR and TYS50204R7M-10 are ROHS3 compliant. The original ELL-5PR4R7N RoHS status is not specified in available documentation.

Q: What is the operating temperature range for these substitutes?

A: Both LMLP05B5N4R7CTAR and TYS50204R7M-10 operate across -40°C to 125°C. The original ELL-5PR4R7N operating temperature range is not specified.

Q: Are packaging formats compatible with existing assembly processes?

A: Both substitutes are supplied in tape and reel (TR) format, standard for automated surface mount assembly. The 5.00mm x 5.00mm footprint and 2.00mm maximum height are compatible with standard pick-and-place equipment.
