ELL-5PS330M Equivalent & Substitute Parts

Part Overview

The ELL-5PS330M is a 33 µH shielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 490 mA with a DC resistance of 470mOhm. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. The part is designed for surface mount applications in nonstandard packaging with unlimited moisture sensitivity rating.

Substitute Part Grouping Explanation

Substitute parts for the ELL-5PS330M are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

Inductance value: 33 µH (exact match required)
Inductance tolerance: ±20% (matching tolerance band)
Shielding: Shielded construction
Mounting type: Surface Mount
Test frequency: 100 kHz

Allowable Variation Parameters:

Current rating: Substitute must meet or exceed 490 mA minimum
DC resistance: Substitute DCR must not exceed 490mOhm maximum
Physical dimensions: Nonstandard package allows minor variations within surface mount constraints
Height: Substitute height must not exceed 2.00mm seated maximum

The two qualified substitutes (CDRH4D14LDNP-330MC and CDRH4D16NP-330MC) from Sumida America Components Inc. meet all critical matching parameters and satisfy allowable variation requirements.

Engineering Selection Recommendations

Both CDRH4D14LDNP-330MC and CDRH4D16NP-330MC are active production components from Sumida America Components Inc., providing long-term availability compared to the obsolete ELL-5PS330M.

CDRH4D14LDNP-330MC offers the lowest DC resistance at 420mOhm maximum and highest current rating at 560 mA, with operating temperature range of -40°C to 105°C. This part is ROHS3 compliant and features a compact height of 1.50mm.

CDRH4D16NP-330MC provides DC resistance of 490mOhm maximum (matching the original specification) and current rating of 530 mA, with operating temperature range of -40°C to 100°C. This part is ROHS3 compliant and features a height of 1.80mm, closer to the original 2.00mm maximum.

Both substitutes feature reduced footprint dimensions (4.60mm x 4.60mm versus 5.00mm x 5.00mm) and lower profile heights, which may require PCB layout verification for mechanical clearance.

Frequently Asked Questions (FAQ)

Q: Can CDRH4D14LDNP-330MC and CDRH4D16NP-330MC be used interchangeably with ELL-5PS330M?

A: Both parts meet the critical electrical specifications: 33 µH inductance at ±20% tolerance, shielded construction, and 100 kHz test frequency. Both exceed the 490 mA current requirement and maintain DC resistance within acceptable limits. Mechanical compatibility requires verification due to reduced footprint dimensions.

Q: What is the primary difference between the two substitute parts?

A: CDRH4D14LDNP-330MC features lower DC resistance (420mOhm) and higher current rating (560 mA) with extended temperature range to 105°C. CDRH4D16NP-330MC matches the original DC resistance specification (490mOhm) and provides intermediate current rating (530 mA) with temperature range to 100°C.

Q: Are there packaging differences between the main part and substitutes?

A: The main part uses nonstandard packaging. Both substitutes are supplied in Tape & Reel (TR) format. The substitutes feature smaller footprints (4.60mm x 4.60mm) and lower heights (1.50mm and 1.80mm respectively) compared to the original 5.00mm x 5.00mm with 2.00mm height.

Q: Do the substitute parts have RoHS compliance?

A: Both CDRH4D14LDNP-330MC and CDRH4D16NP-330MC are ROHS3 compliant. RoHS status for the original ELL-5PS330M is not specified.

Q: What is the moisture sensitivity level for these parts?

A: All three parts carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.
