Key Parameters

Substitute Part Grouping Explanation

Substitution of the UP1B-6R8-R is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 6.8 µH (exact match required)
• Tolerance: ±20% (standard tolerance band)
• Core type: Ferrite drum core, wirewound construction
• Shielding configuration: Unshielded
• Mounting technology: Surface mount

Secondary Compatibility Factors:

• Current rating must equal or exceed 1.7 A
• DC resistance must not exceed 89.7 mOhm
• Operating temperature range must encompass -40°C to 85°C minimum
• RoHS compliance status must be maintained
• MSL rating of 1 or better

The SDR0805-6R8ML from Bourns Inc. satisfies all primary matching criteria and exceeds secondary compatibility requirements, qualifying as a direct substitute.

Engineering Selection Recommendations

UP1B-6R8-R Selection Criteria:

• Primary choice when Eaton component availability and supply chain continuity are prioritized
• Active product status ensures ongoing manufacturer support
• RoHS Compliant certification meets environmental regulatory requirements
• Suitable for applications with current requirements up to 1.7 A

SDR0805-6R8ML Selection Criteria:

• Recommended when enhanced electrical performance is required
• Superior current rating (3.2 A) and saturation current (4.1 A) provide design margin
• Lower DC resistance (40 mOhm Max) reduces power dissipation compared to UP1B-6R8-R
• Extended operating temperature range (-40°C ~ 125°C) accommodates broader thermal environments
• ROHS3 Compliant status reflects current regulatory alignment
• Active product status ensures manufacturer continuity

Both components maintain identical inductance, tolerance, core material, shielding, and mounting characteristics. Selection between these parts depends on application-specific current requirements, thermal environment, and supply chain preferences.

Frequently Asked Questions (FAQ)

Q: Can SDR0805-6R8ML directly replace UP1B-6R8-R in existing designs?

A: Yes. Both inductors share identical inductance (6.8 µH), tolerance (±20%), core material (ferrite), shielding (unshielded), and surface mount packaging. The SDR0805-6R8ML provides superior electrical performance with higher current rating and lower DC resistance.

Q: What are the physical dimension differences between these parts?

A: UP1B-6R8-R dimensions are 0.350" L x 0.240" W x 0.197" H (8.89mm x 6.10mm x 5.00mm). SDR0805-6R8ML dimensions are 0.307" L x 0.307" W x 0.209" H (7.80mm x 7.80mm x 5.30mm). The SDR0805 footprint is more compact in length and width. PCB layout verification is required when substituting.

Q: Are there temperature rating implications for substitution?

A: UP1B-6R8-R operates -40°C to 85°C. SDR0805-6R8ML operates -40°C to 125°C. For applications within the -40°C to 85°C range, both parts are functionally equivalent. For applications exceeding 85°C, only SDR0805-6R8ML is suitable.

Q: How do DC resistance values affect circuit performance?

A: UP1B-6R8-R has 89.7 mOhm maximum DCR; SDR0805-6R8ML has 40 mOhm maximum DCR. Lower resistance reduces I²R power losses. In high-current or efficiency-critical applications, SDR0805-6R8ML dissipates less heat.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both UP1B-6R8-R and SDR0805-6R8ML are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: What compliance certifications apply to both parts?

A: UP1B-6R8-R is RoHS Compliant with MSL 1 (Unlimited). SDR0805-6R8ML is ROHS3 Compliant with MSL 1 (Unlimited) and REACH Unaffected status. Both meet current environmental and regulatory standards.
