Key Parameters

Substitute Part Grouping Explanation

Substitution of the CSBX1809-6R8M is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Inductance value: 6.8 µH with ±20% tolerance
• Current rating: 18.5 A minimum
• Saturation current: 31 A minimum
• DC resistance: 4.7 mOhm maximum

Mechanical Parameters:

• Wirewound construction with metal composite core
• Shielded configuration
• Surface mount technology
• Nonstandard package dimensions: 19.30 mm L x 18.20 mm W x 9.20 mm H maximum

Environmental & Compliance Parameters:

• Operating temperature range: -55°C to 150°C
• AEC-Q200 automotive qualification
• ROHS3 compliance
• MSL 1 rating
• REACH unaffected status

Substitute parts must match all electrical specifications, maintain identical mechanical form factor and mounting characteristics, and retain all environmental certifications and compliance ratings. No parameter relaxation or derating is permitted for substitution eligibility.

Engineering Selection Recommendations

The CSBX1809-6R8M maintains Active product status with continuous manufacturing availability and full AEC-Q200 automotive qualification. This component is suitable for applications requiring high saturation inductors in automotive and industrial power conversion circuits.

Selection of equivalent parts must prioritize:

Compliance Verification: All substitute parts must retain AEC-Q200 certification, ROHS3 compliance, and REACH unaffected status to maintain design integrity in regulated applications.

Electrical Performance: Exact matching of 6.8 µH inductance, 18.5 A current rating, and 31 A saturation current is required. DC resistance must not exceed 4.7 mOhm to preserve circuit efficiency and thermal characteristics.

Mechanical Compatibility: The nonstandard 19.30 mm x 18.20 mm x 9.20 mm form factor is specific to this design. Substitute parts must match these dimensions precisely to ensure PCB layout compatibility and thermal management performance.

Environmental Ratings: The -55°C to 150°C operating temperature range and MSL 1 rating must be maintained. These parameters are critical for automotive and high-reliability applications.

The CSBX1809-6R8M from CODACA represents the primary specification for this application. Direct part number matching ensures optimal performance and eliminates compatibility risk.

Frequently Asked Questions (FAQ)

Q: What defines an equivalent part for the CSBX1809-6R8M?

A: An equivalent part must match all electrical parameters (6.8 µH inductance, 18.5 A current rating, 31 A saturation current, 4.7 mOhm maximum DCR), maintain identical wirewound metal composite shielded construction, preserve the nonstandard 19.30 mm x 18.20 mm x 9.20 mm form factor, and retain AEC-Q200, ROHS3, and REACH compliance ratings.

Q: Can the CSBX1809-6R8M be substituted with a different inductance value?

A: No. The 6.8 µH inductance value is a critical circuit parameter. Substitution with different inductance values alters circuit performance and is not permitted.

Q: Is the ±20% inductance tolerance acceptable for substitution?

A: Yes. The ±20% tolerance is the specified manufacturing tolerance for this part. Any substitute part must operate within this same tolerance band at the 100 kHz test frequency.

Q: What is the significance of the 31 A saturation current rating?

A: The 31 A saturation current defines the maximum current level before the inductor enters saturation and inductance degrades. Substitute parts must meet or exceed this specification to maintain performance under peak load conditions.

Q: Does the shielded construction affect substitution options?

A: Yes. The shielded wirewound design is essential for EMI suppression in power conversion applications. Substitute parts must maintain shielded construction to prevent electromagnetic interference in adjacent circuits.

Q: Are there packaging considerations for the CSBX1809-6R8M?

A: The component is supplied in Tape & Reel (TR) packaging. The nonstandard case dimensions (19.30 mm x 18.20 mm x 9.20 mm) are specific to this design. Substitute parts must use identical packaging format and dimensions for PCB assembly compatibility.

Q: What is the importance of AEC-Q200 certification?

A: AEC-Q200 certification indicates the component meets automotive-grade reliability and performance standards. This certification is mandatory for automotive applications and must be retained in any substitute part.

Q: Can the CSBX1809-6R8M operate outside the -55°C to 150°C temperature range?

A: No. The specified operating temperature range defines the limits for reliable operation. Operation outside this range voids performance guarantees and may cause component failure.

Q: What does ROHS3 compliance mean for this inductor?

A: ROHS3 compliance indicates the component is manufactured without restricted hazardous substances (lead, cadmium, mercury, hexavalent chromium, PBBs, PBDEs). This compliance is required for products sold in regulated markets.

Q: Is MSL 1 rating important for storage and handling?

A: Yes. MSL 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. This simplifies inventory management and reduces component degradation risk.
