Substitute Part Grouping Explanation

Substitution of the 0805-751K is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

• Inductance value: 750 nH (exact match required)
• Mounting type: Surface mount
• Operating temperature range: -40°C to 125°C minimum
• Core type: Unshielded drum core wirewound construction
• Package classification: 0805 (2012 Metric) form factor compatibility

The substitute part CW201212-R75J from Bourns Inc. satisfies these criteria. While the substitute exhibits a tighter tolerance specification (±5% versus ±10%) and utilizes ferrite core material instead of ceramic, both components maintain the same inductance value, unshielded configuration, surface mount deployment, and operating temperature envelope. The ferrite core material in the substitute provides improved Q factor characteristics at the specified test frequency of 50 MHz.

Parameter Comparison

Engineering Selection Recommendations

The CW201212-R75J from Bourns Inc. is the designated equivalent substitute for the obsolete 0805-751K. Selection of this substitute is supported by the following engineering factors:

Product Status: The substitute maintains active product status with confirmed inventory availability (856 Pcs), ensuring long-term procurement viability compared to the obsolete original part.

Compliance Posture: The CW201212-R75J achieves ROHS3 compliance and maintains REACH unaffected status, aligning with current regulatory requirements. The original 0805-751K is RoHS non-compliant, making the substitute the preferred choice for new designs and compliance-sensitive applications.

Electrical Equivalence: Both components operate at identical inductance values (750 nH) and temperature ranges (-40°C to 125°C). The substitute's tighter tolerance specification (±5%) provides improved consistency compared to the original ±10% tolerance.

Physical Compatibility: The substitute footprint (0.083" L × 0.058" W) is dimensionally similar to the original nonstandard package, with equivalent seated height (0.059" versus 0.060"), supporting direct board-level substitution in most applications.

Core Material Consideration: The ferrite core material in the substitute differs from the ceramic core in the original part. This material change does not affect inductance equivalence but may influence frequency response characteristics in specific circuit topologies. Verification of frequency-dependent performance is required only for applications operating near the self-resonant frequency range.

Frequently Asked Questions (FAQ)

Q: Can the CW201212-R75J directly replace the 0805-751K without PCB modification?

A: The substitute exhibits compatible physical dimensions and mounting type. The footprint difference (0.090" × 0.068" versus 0.083" × 0.059") is within typical PCB design tolerances for surface mount placement. Direct substitution is supported without PCB redesign in standard applications.

Q: What is the impact of the ferrite core material change on circuit performance?

A: The ferrite core material in the substitute provides different frequency response characteristics compared to the ceramic core in the original part. Both maintain the specified 750 nH inductance value. Applications requiring specific Q factor or frequency response characteristics should evaluate the substitute's performance at the intended operating frequency.

Q: Does the tighter tolerance (±5%) of the substitute provide any advantage?

A: The CW201212-R75J tolerance of ±5% is tighter than the original ±10% specification. This provides improved component consistency and reduced circuit parameter variation, which is beneficial for precision applications. Existing designs tolerant of ±10% variation will operate within specification with the substitute.

Q: Is the substitute suitable for RoHS-compliant applications?

A: Yes. The CW201212-R75J is ROHS3 compliant, making it suitable for applications requiring RoHS compliance. The original 0805-751K is RoHS non-compliant and cannot be used in RoHS-mandated applications.

Q: What is the current rating of the CW201212-R75J?

A: The current rating specification for the CW201212-R75J is not provided in the available technical data. The original 0805-751K is rated for 180 mA. Verification of current handling capability is required through the manufacturer's detailed datasheet before application in current-limited circuits.

Q: Are there any packaging differences between the original and substitute?

A: The original part is supplied in nonstandard packaging, while the substitute (CW201212-R75J) is supplied in Tape & Reel (TR) format. This packaging difference supports automated assembly processes and improves handling efficiency in production environments.
