ELL-6SH8R2M Equivalent & Substitute Parts

Part Overview

The ELL-6SH8R2M is an 8.2 µH shielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 1.4 A with a DC resistance of 61mOhm. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. 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). ROHS3 compliance and MSL 1 rating ensure environmental and moisture handling standards are met.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELL-6SH8R2M are qualified based on the following critical parameters:

Primary Matching Criteria:

• Inductance value: 8.2 µH (exact match required)
• Shielding: Shielded configuration
• Mounting type: Surface mount
• Inductance test frequency: 100 kHz

Secondary Compatibility Parameters:

• Current rating: Equal to or greater than 1.4 A
• DC resistance: Within acceptable operating limits for the application
• Package dimensions: Compatible with PCB layout constraints
• Environmental compliance: ROHS3 and MSL ratings maintained

The two substitute parts listed below meet these criteria while offering improved current handling and active product status compared to the obsolete ELL-6SH8R2M.

Parameter Comparison

Engineering Selection Recommendations

CDRH5D28RHPNP-8R2NC (Sumida America Components Inc.): This substitute offers a 35.7% increase in current rating (1.9 A vs. 1.4 A) with a ferrite core construction. The part is active in production, ROHS3 compliant, and maintains MSL 1 rating. Package dimensions are slightly smaller (6.00mm × 5.90mm × 3.00mm), which may provide PCB layout advantages. DC resistance increases to 88.4mOhm maximum, which should be evaluated against thermal and efficiency requirements. Operating temperature range of -40°C to 105°C is specified.

SRR5028-8R2Y (Bourns Inc.): This substitute provides the highest current rating (2.1 A) and the lowest DC resistance (55mOhm maximum), representing a 10% improvement over the original part. The drum core, wirewound construction with ferrite core offers enhanced performance characteristics. The part is active in production with ROHS3 compliance and MSL 1 rating. Package dimensions are the most compact (5.80mm × 5.80mm × 3.00mm). Operating temperature range extends to -40°C to 125°C, providing broader thermal operating margins. Self-resonant frequency of 34 MHz and Q factor of 7 @ 7.96MHz are specified.

Both substitutes are suitable for applications requiring the 8.2 µH inductance value with shielded surface mount configuration. Selection between them depends on specific requirements for current headroom, DC resistance performance, thermal operating range, and PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can the CDRH5D28RHPNP-8R2NC or SRR5028-8R2Y be used as direct replacements for the ELL-6SH8R2M?

A: Both parts meet the core substitution criteria: 8.2 µH inductance, shielded configuration, surface mount mounting, and 100 kHz test frequency. However, differences in DC resistance, current rating, and package dimensions must be evaluated against specific circuit requirements. The smaller package footprints of the substitutes may require PCB layout verification.

Q: What is the impact of increased DC resistance in the CDRH5D28RHPNP-8R2NC?

A: The CDRH5D28RHPNP-8R2NC has a maximum DC resistance of 88.4mOhm compared to 61mOhm in the original part. This 45% increase results in higher resistive losses and heat generation. Applications sensitive to power dissipation or thermal performance should prioritize the SRR5028-8R2Y, which offers 55mOhm maximum resistance.

Q: Are there package compatibility concerns with the substitute parts?

A: The substitute parts have smaller package dimensions than the ELL-6SH8R2M. The CDRH5D28RHPNP-8R2NC measures 6.00mm × 5.90mm × 3.00mm, and the SRR5028-8R2Y measures 5.80mm × 5.80mm × 3.00mm, compared to the original 6.40mm × 6.00mm × 3.30mm. These differences are minor and typically accommodate existing PCB footprints designed for the original part. Verify pad spacing and clearance requirements for your specific application.

Q: What are the tolerance differences between the main part and substitutes?

A: The ELL-6SH8R2M has ±20% tolerance, while the CDRH5D28RHPNP-8R2NC has ±25% and the SRR5028-8R2Y has ±30%. Wider tolerances in the substitutes may affect circuit performance in applications with tight inductance specifications. Evaluate tolerance impact on filter response, resonant frequency, or impedance matching requirements.

Q: Do the substitute parts maintain the same environmental compliance?

A: Yes, both substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) ratings, matching the environmental standards of the original ELL-6SH8R2M. The SRR5028-8R2Y additionally carries REACH Unaffected status.

Q: What is the significance of the higher current ratings in the substitutes?

A: The CDRH5D28RHPNP-8R2NC (1.9 A) and SRR5028-8R2Y (2.1 A) offer greater current handling capacity than the original 1.4 A rating. This provides design margin for applications operating near the original current limit and reduces thermal stress on the component during normal operation.
