Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PM628S-820-RC is determined by strict equivalence across the following critical parameters:

• Inductance value: 82 µH
• Inductance tolerance: ±30%
• Current rating: 700 mA minimum
• Saturation current (Isat): 560 mA minimum
• DC resistance: 400 mOhm maximum
• Shielding: Shielded configuration required
• Core material: Ferrite
• Core type: Drum core, wirewound
• Operating temperature range: -40°C to 125°C minimum
• Mounting type: Surface mount
• Package dimensions: 0.268" L x 0.268" W (6.80 mm x 6.80 mm)
• Height: 0.118" (3.00 mm) maximum
• Packaging format: Tape & Reel (TR)
• Compliance: ROHS3 compliant, MSL 1

The SRR6028-820Y meets all specified parameters and qualifies as a direct substitute for the PM628S-820-RC.

Parameter Comparison

Engineering Selection Recommendations

Both the PM628S-820-RC and SRR6028-820Y are active production components from Bourns Inc. with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability, supply chain lead times, or manufacturing process requirements. The PM628S-820-RC currently maintains 1058 pieces in stock, while the SRR6028-820Y has 1943 pieces available. Both components carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The difference in series designation (PM628S versus SRR6028) reflects internal Bourns product line organization but does not affect functional equivalence for circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the SRR6028-820Y be used as a direct replacement for the PM628S-820-RC in existing designs?

A: Yes. The SRR6028-820Y is electrically and mechanically equivalent to the PM628S-820-RC across all specified parameters, including inductance, current rating, DC resistance, shielding, core material, package dimensions, and operating temperature range. No circuit modifications are required.

Q: Are there any differences in the physical footprint between these two parts?

A: No. Both parts share identical package dimensions of 0.268" L x 0.268" W (6.80 mm x 6.80 mm) with a maximum seated height of 0.118" (3.00 mm). PCB layout and assembly processes remain unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the PM628S-820-RC and SRR6028-820Y are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level) and REACH unaffected status.

Q: What is the significance of the different series designations (PM628S versus SRR6028)?

A: The series designation reflects Bourns Inc. internal product line categorization. From an engineering perspective, both series share identical electrical performance and mechanical specifications for this 82 µH inductor application.

Q: Are there any frequency-dependent performance differences between these parts?

A: No. Both parts exhibit identical Q factor (9 @ 796 kHz), self-resonant frequency (14 MHz), and inductance test frequency (100 kHz).

Q: Which part should be selected based on current availability?

A: Selection may be based on supply chain requirements. The SRR6028-820Y currently has higher inventory (1943 pieces) compared to the PM628S-820-RC (1058 pieces). Both are active production components with equivalent lead times and availability.
