Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0805-751J is based on the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Inductance value: 750 nH (exact match required)
• Inductance tolerance: ±5% (matching tolerance specification)
• Operating temperature range: -40°C to 125°C (minimum requirement)
• Mounting type: Surface mount (form factor compatibility)
• Shielding configuration: Unshielded (electromagnetic environment compatibility)

Secondary Compatibility Factors:

• Current rating: Substitute must support minimum 180 mA operation
• DC resistance: Substitute DCR must not exceed application thermal and loss requirements
• Package classification: 0805 (2012 Metric) standard footprint

The CW201212-R75J from Bourns Inc. satisfies the primary substitution criteria through matching inductance value, tolerance, operating temperature range, and surface mount configuration. Both components are unshielded drum core wirewound inductors with identical inductance specifications and tolerance bands.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The CW201212-R75J is electrically equivalent to the 0805-751J for applications requiring 750 nH inductance with ±5% tolerance across the -40°C to 125°C operating range. Both components share identical inductance specifications, tolerance bands, and operating temperature ratings, establishing functional equivalence for the core inductive function.

Compliance Considerations:

The CW201212-R75J holds ROHS3 compliance status, whereas the 0805-751J is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the Bourns substitute provides compliance alignment. Both components are REACH Unaffected and classified under ECCN EAR99.

Product Status Impact:

The 0805-751J is classified as obsolete, creating supply chain risk and limiting procurement options. The CW201212-R75J maintains active product status with documented inventory availability, supporting long-term design continuity and supply chain reliability.

Physical and Material Differences:

The CW201212-R75J uses ferrite core material compared to the ceramic core of the 0805-751J. The Bourns component features standard 0805 (2012 Metric) package classification with slightly reduced physical dimensions (2.10mm x 1.50mm versus 2.29mm x 1.73mm). These dimensional differences remain within typical PCB layout tolerances for 0805 footprint applications.

Electrical Parameter Gaps:

The CW201212-R75J does not specify current rating, DC resistance, Q factor, or self-resonant frequency in the provided data. Applications requiring verification of these parameters against specific design constraints must obtain complete electrical characterization from the manufacturer.

Frequently Asked Questions (FAQ)

Q: Can the CW201212-R75J directly replace the 0805-751J in existing designs?

A: The CW201212-R75J provides electrical equivalence for the 750 nH inductance specification with matching tolerance and operating temperature range. Physical dimensions differ slightly (2.10mm x 1.50mm versus 2.29mm x 1.73mm), requiring PCB layout verification. The ferrite core material differs from the original ceramic core, which may affect high-frequency performance characteristics not specified in the provided data.

Q: What are the key differences between these two inductors?

A: Primary differences include core material (ferrite versus ceramic), package classification (standard 0805 versus nonstandard), physical dimensions, and product status (active versus obsolete). Both components maintain identical inductance values, tolerance specifications, and operating temperature ranges.

Q: Is the CW201212-R75J suitable for RoHS-compliant applications?

A: Yes. The CW201212-R75J holds ROHS3 compliance certification, making it suitable for applications subject to RoHS regulatory requirements. The original 0805-751J is RoHS non-compliant.

Q: How do the physical dimensions affect PCB layout?

A: The CW201212-R75J (2.10mm x 1.50mm) is slightly smaller than the 0805-751J (2.29mm x 1.73mm). Standard 0805 footprints accommodate both components. Height differences are negligible (1.50mm versus 1.52mm seated height). PCB layout verification is recommended to confirm clearance and thermal management compatibility.

Q: What electrical parameters require verification before substitution?

A: The provided data does not specify current rating, DC resistance, Q factor, or self-resonant frequency for the CW201212-R75J. Applications with specific requirements for these parameters must obtain complete electrical characterization from Bourns Inc. to confirm suitability for the intended circuit function.

Q: Are both components available for procurement?

A: The 0805-751J is classified as obsolete with limited inventory (862 pieces). The CW201212-R75J maintains active product status with documented availability (856 pieces). For new designs or long-term production, the active Bourns component provides superior supply chain continuity.
