ELL-6SH820M Equivalent & Substitute Parts

Part Overview

The ELL-6SH820M is an 82 µH shielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 450 mA with 600mOhm 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 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-6SH820M are qualified based on the following electrical and mechanical parameters:

Electrical Criteria:

• Inductance value: 82 µH (core requirement)
• Inductance tolerance: ±20% or tighter
• Current rating: minimum 450 mA
• DC resistance: 600mOhm or lower
• Shielding: Shielded construction
• Inductance test frequency: 100 kHz

Mechanical Criteria:

• Mounting type: Surface Mount
• Package classification: Nonstandard
• Physical dimensions: compatible with 6.40mm × 6.00mm footprint and 3.30mm max height constraints

Compliance Criteria:

• RoHS3 compliance required
• MSL rating: 1 (Unlimited)

Three substitute parts meet these criteria: SRR5028-820Y (Bourns Inc.), SC62CB-820 (Signal Transformer), and S3483R-820M (API Delevan Inc.). All are active products with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with ROHS3 compliance and MSL 1 ratings, providing long-term procurement viability compared to the obsolete ELL-6SH820M.

SRR5028-820Y (Bourns Inc.) offers the lowest DC resistance at 430mOhm maximum and highest current rating at 520 mA. The extended operating temperature range (-40°C ~ 125°C) supports wider environmental applications. Physical dimensions (5.80mm × 5.80mm × 3.00mm) are smaller than the original part, enabling space optimization in compact designs. Inductance tolerance is ±30%, which is wider than the original ±20%.

SC62CB-820 (Signal Transformer) provides the highest current rating at 610 mA and maintains the original ±20% inductance tolerance. The lowest profile height at 2.50mm accommodates space-constrained applications. Operating temperature range extends to -40°C ~ 125°C. DC resistance at 670mOhm is slightly elevated compared to the original specification.

S3483R-820M (API Delevan Inc.) matches the original DC resistance specification at 600mOhm maximum and maintains ±20% inductance tolerance. Current rating of 460 mA closely aligns with the original 450 mA specification. Operating temperature range is -20°C ~ 85°C, narrower than competing substitutes. Physical dimensions (7.20mm × 7.20mm × 4.60mm) are larger than the original part.

Frequently Asked Questions (FAQ)

Q: Can SRR5028-820Y replace ELL-6SH820M in all applications?

A: SRR5028-820Y meets all electrical substitution criteria with superior current rating (520 mA vs. 450 mA) and lower DC resistance (430mOhm vs. 600mOhm). However, the ±30% inductance tolerance is wider than the original ±20%. Physical dimensions are smaller (5.80mm × 5.80mm vs. 6.40mm × 6.00mm), which may require PCB layout verification. The extended operating temperature range (-40°C ~ 125°C) provides additional environmental coverage.

Q: What are the DC resistance differences among substitutes?

A: SRR5028-820Y offers the lowest DC resistance at 430mOhm maximum, reducing power dissipation by approximately 28% compared to the original 600mOhm specification. SC62CB-820 has the highest DC resistance at 670mOhm maximum, increasing dissipation by approximately 12%. S3483R-820M matches the original specification at 600mOhm maximum.

Q: Are there package footprint compatibility concerns?

A: All substitutes use nonstandard surface mount packages with different physical dimensions. SRR5028-820Y (5.80mm × 5.80mm) and SC62CB-820 (6.30mm × 6.20mm) are smaller than the original (6.40mm × 6.00mm), while S3483R-820M (7.20mm × 7.20mm) is larger. Height variations range from 2.50mm to 4.60mm compared to the original 3.30mm. PCB layout and component placement must be verified for each substitute.

Q: Which substitute provides the best thermal performance?

A: SRR5028-820Y and SC62CB-820 both support the extended operating temperature range of -40°C ~ 125°C, compared to S3483R-820M at -20°C ~ 85°C. SRR5028-820Y's lower DC resistance (430mOhm) generates less heat during operation, providing superior thermal performance in current-limited applications.

Q: Do all substitutes maintain RoHS3 and MSL compliance?

A: All three substitute parts are ROHS3 compliant with MSL 1 (Unlimited) ratings, matching the original ELL-6SH820M specifications. This ensures consistent environmental and moisture handling requirements across all options.
