ELL-6SH2R7M Equivalent & Substitute Parts

Part Overview

The ELL-6SH2R7M is a 2.7 µH shielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 2.4 A with a DC resistance of 31 mOhm. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. The part operates at 100 kHz inductance test frequency and is housed in a nonstandard surface mount package measuring 6.40mm × 6.00mm × 3.30mm (max height).

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELL-6SH2R7M are selected based on the following critical parameters:

• Inductance Value: Substitute parts must maintain 2.7 µH (or 2.6 µH within tolerance range)
• Shielding Requirement: All substitutes must be shielded to maintain electromagnetic isolation
• Current Rating: Substitute parts must support minimum 2.4 A operation
• DC Resistance: Substitute parts must maintain comparable DCR performance (23–31 mOhm range)
• Mounting Configuration: All substitutes are surface mount, nonstandard package types
• Compliance: All substitutes maintain ROHS3 compliance and MSL 1 rating

Two qualified substitute parts meet these criteria: SC63CB-2R7 (Signal Transformer) and SRR5028-2R6Y (Bourns Inc.).

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with full ROHS3 compliance and MSL 1 ratings, providing long-term procurement stability compared to the obsolete ELL-6SH2R7M.

SC63CB-2R7 (Signal Transformer): This substitute provides exact inductance matching at 2.7 µH with higher current rating (3.6 A) and lower DC resistance (23 mOhm Max). Physical dimensions are nearly identical to the main part (6.30mm × 6.20mm vs. 6.40mm × 6.00mm), with slightly increased height (4.60mm vs. 3.30mm). Saturation current of 2.69 A exceeds the main part's 2.4 A requirement.

SRR5028-2R6Y (Bourns Inc.): This substitute offers inductance of 2.6 µH (within tolerance of 2.7 µH specification), rated for 3 A with DC resistance of 30 mOhm Max. The part features a ferrite drum core construction with documented Q factor (7 @ 7.96MHz) and self-resonant frequency (77MHz). Physical footprint is more compact (5.80mm × 5.80mm × 3.00mm), providing space savings in layout-constrained applications. Saturation current of 2.7 A meets the main part's 2.4 A requirement.

Frequently Asked Questions (FAQ)

Q: Can SC63CB-2R7 and SRR5028-2R6Y be used interchangeably with ELL-6SH2R7M?

A: Both parts meet the core electrical requirements (2.6–2.7 µH inductance, shielded construction, ≥2.4 A current rating, ≤31 mOhm DCR). However, physical dimensions differ. SC63CB-2R7 maintains near-identical footprint dimensions, while SRR5028-2R6Y is more compact. PCB layout compatibility must be verified before substitution.

Q: What is the impact of inductance tolerance differences?

A: The main part specifies ±20% tolerance, while both substitutes specify ±30%. For applications requiring tighter inductance control, the main part's tolerance is superior. However, both substitutes remain within acceptable operating ranges for standard inductor applications at 100 kHz test frequency.

Q: Are there height clearance concerns with SC63CB-2R7?

A: SC63CB-2R7 has a maximum seated height of 4.60mm compared to the main part's 3.30mm. This 0.20mm increase may impact designs with tight vertical constraints. SRR5028-2R6Y offers reduced height at 3.00mm, providing additional clearance margin.

Q: Do the substitute parts maintain shielding performance?

A: Both substitute parts are specified as shielded inductors, meeting the electromagnetic isolation requirement of the main part. Shielding effectiveness is maintained across all three parts.

Q: What is the significance of product status (Active vs. Obsolete)?

A: The main part (ELL-6SH2R7M) is obsolete, indicating discontinued manufacturing and limited future availability. Both substitutes are active products with ongoing production, ensuring long-term procurement reliability and supply chain continuity.

Q: Are all parts RoHS3 compliant?

A: Yes. The main part and both substitutes are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and reliability standards.
