236R8C Equivalent & Substitute Parts

Part Overview

The 236R8C is a 6.8 µH unshielded wirewound surface mount inductor manufactured by Murata Power Solutions. Rated for 1.22 A continuous current with a maximum DC resistance of 102mOhm, this component is designed for applications requiring compact, fixed inductance in the microhenry range. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating, making it suitable for industrial and commercial electronics applications.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design flexibility permits selection from qualified alternatives that meet or exceed the electrical and mechanical requirements of the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 236R8C is determined by the following critical parameters:

Mandatory Matching Criteria:

• Inductance value: 6.8 µH (exact match required)
• Mounting type: Surface Mount
• Physical footprint: 4.50mm x 4.00mm length and width
• Shielding configuration: Unshielded

Allowable Variation Criteria:

• Current rating: Substitute must equal or exceed 1.22 A
• DC resistance: Substitute must not exceed 102mOhm maximum
• Operating temperature range: Substitute must cover or exceed -40°C ~ 85°C
• Height: Substitute seated height must not exceed 0.126" (3.20mm) to ensure PCB assembly compatibility

The SDR0403-6R8ML from Bourns Inc. qualifies as a direct substitute based on matching inductance, identical footprint dimensions, surface mount configuration, and unshielded design. The substitute provides superior current handling (1.41 A vs. 1.22 A) and extended operating temperature range (-40°C ~ 125°C vs. -40°C ~ 85°C), while maintaining DC resistance within acceptable limits.

Parameter Comparison

Engineering Selection Recommendations

Both the 236R8C and SDR0403-6R8ML are active production components with full RoHS3 compliance and REACH unaffected status, qualifying them for use in regulated industrial and commercial applications. The SDR0403-6R8ML provides enhanced performance margins through higher current rating and extended temperature range, making it suitable for applications with demanding thermal or current requirements.

The primary consideration for component selection is the seated height differential of 0.012" (0.30mm). Applications with tight vertical clearance constraints on the PCB assembly must verify that the SDR0403-6R8ML height of 0.138" (4.60mm) is compatible with the design layout. For applications without height restrictions, the Bourns substitute offers superior performance characteristics while maintaining electrical equivalence.

Both components are supplied in Tape & Reel packaging suitable for automated assembly processes. Inventory availability should be evaluated based on current procurement requirements and supply chain lead times.

Frequently Asked Questions (FAQ)

Q: Can the SDR0403-6R8ML be used as a direct replacement for the 236R8C in all applications?

A: The SDR0403-6R8ML is electrically and mechanically compatible with the 236R8C for applications where the seated height of 0.138" (4.60mm) does not exceed design constraints. The substitute provides equal or superior performance across all specified electrical parameters. PCB layout verification is required to confirm height compatibility.

Q: What is the significance of the DC resistance difference between the two parts?

A: The 236R8C specifies 102mOhm maximum DC resistance, while the SDR0403-6R8ML specifies 120mOhm maximum. This 18mOhm difference represents approximately 18% higher resistance in the substitute. For applications sensitive to resistive losses or thermal dissipation, this parameter must be evaluated against circuit performance requirements.

Q: Are both parts suitable for automated PCB assembly?

A: Yes. Both components are supplied in Tape & Reel packaging and feature identical footprint dimensions (4.50mm x 4.00mm), enabling use with standard surface mount assembly equipment. The height difference of 0.012" requires verification that pick-and-place tooling and reflow profiles accommodate the SDR0403-6R8ML maximum seated height.

Q: What are the core material differences between these inductors?

A: The 236R8C uses an unspecified core material, while the SDR0403-6R8ML uses a ferrite drum core. Both are unshielded designs. The ferrite core in the Bourns part contributes to its higher saturation current rating (2.1A) and extended frequency performance (40MHz self-resonant frequency).

Q: Do both parts meet the same compliance and regulatory requirements?

A: Yes. Both the 236R8C and SDR0403-6R8ML are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8504.50.4000. Both carry MSL 1 (Unlimited) moisture sensitivity rating, suitable for standard storage and handling conditions.
