ELL-CTV102M Equivalent & Substitute Parts

Part Overview

The ELL-CTV102M is a 1 mH shielded drum core, wirewound inductor manufactured by Panasonic Electronic Components. Designed for surface mount applications, this component features a 410 mA current rating and 1.5Ohm DC resistance. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitute parts for the ELL-CTV102M are qualified based on the following electrical and mechanical parameters:

Inductance Value: 1 mH (primary matching criterion)
Inductance Tolerance: ±20% or tighter
Current Rating: Equal to or greater than 410 mA
DC Resistance: Comparable to 1.5Ohm (maximum acceptable variance determined by circuit requirements)
Core Material: Ferrite shielded construction
Mounting Type: Surface mount
Inductance Test Frequency: 100 kHz
Environmental Compliance: ROHS3 compliant

The two qualified substitutes meet these criteria while offering active product status and improved availability compared to the obsolete ELL-CTV102M.

Engineering Selection Recommendations

CDRR107NP-102MC (Sumida America Components Inc.)

This substitute provides the closest electrical match to the ELL-CTV102M with a current rating of 470 mA (exceeding the original 410 mA requirement) and DC resistance of 1.43Ohm Max (lower than the original 1.5Ohm). The part is active and available in high volume. Physical dimensions are slightly smaller (11.00mm x 11.00mm versus 12.00mm x 12.00mm), but height is significantly greater at 10.00mm. PCB layout verification is required to confirm height compatibility. Operating temperature range of -40°C to 125°C is specified.

SRR1260-102K (Bourns Inc.)

This substitute offers superior electrical performance with a current rating of 680 mA and tighter inductance tolerance of ±10% (versus ±20%). DC resistance is 1.7Ohm Max, representing a 13% increase over the original specification. The part is active with extensive inventory availability. Physical dimensions are 12.50mm x 12.50mm with a height of 6.50mm, requiring PCB footprint verification. Operating temperature range of -40°C to 125°C and ROHS3 compliance are confirmed. Additional performance data including Q factor (30 @ 252kHz) and self-resonant frequency (1.8MHz) are provided.

Both substitutes are ROHS3 compliant and suitable for applications requiring the electrical characteristics of the ELL-CTV102M. Selection between them depends on specific PCB layout constraints, thermal requirements, and tolerance specifications of the target application.

Frequently Asked Questions (FAQ)

Q: Can the CDRR107NP-102MC be used as a direct replacement for the ELL-CTV102M?

A: The CDRR107NP-102MC meets the core electrical requirements: 1 mH inductance, ±20% tolerance, 470 mA current rating (exceeding 410 mA), and comparable DC resistance of 1.43Ohm Max. However, the height of 10.00mm versus 4.50mm for the original part requires verification against PCB clearance constraints and component placement density.

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

A: The SRR1260-102K provides higher current capacity (680 mA versus 470 mA) and tighter inductance tolerance (±10% versus ±20%). The CDRR107NP-102MC offers lower DC resistance (1.43Ohm Max versus 1.7Ohm Max) and a smaller footprint (11.00mm x 11.00mm). DC resistance differences may impact thermal performance in high-current applications.

Q: Are both substitutes available in the same packaging format?

A: Both substitutes are supplied in Tape & Reel (TR) packaging, which differs from the original ELL-CTV102M packaging specification. Verify that your procurement and assembly processes support this packaging format.

Q: Do the substitutes have specified operating temperature ranges?

A: Both the CDRR107NP-102MC and SRR1260-102K specify an operating temperature range of -40°C to 125°C. The original ELL-CTV102M does not provide an operating temperature specification in the available data.

Q: Which substitute has better long-term availability?

A: The SRR1260-102K is currently in active production
