Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BNX005-01 is determined by strict equivalence across the following critical parameters:

• Filter configuration: 5th order LC low-pass topology
• Channel count: 2 channels
• Current capacity: 15 A minimum
• Attenuation performance: 40dB @ 1MHz ~ 1GHz
• Voltage rating: 50V minimum
• Mounting method: Through-hole
• Package form factor: Block, 4-lead configuration
• Regulatory compliance: ROHS3 compliance

The BNX005-11 qualifies as a direct substitute based on identical electrical specifications, matching mechanical dimensions within tolerance, and equivalent regulatory certifications. The primary distinction is product status: BNX005-11 maintains Active status with expanded temperature range capability.

Parameter Comparison

Engineering Selection Recommendations

The BNX005-11 is the qualified substitute for the obsolete BNX005-01 based on the following engineering criteria:

Electrical Equivalence: Both parts deliver identical filter performance with 5th order LC topology, 2-channel configuration, 15A current capacity, and 40dB attenuation across the 1MHz to 1GHz band. Voltage rating and ESD characteristics are equivalent.

Mechanical Compatibility: Package form factor, mounting method, and board-level dimensions are identical. Height variance (14.60mm vs. 13.00mm) falls within standard PCB assembly tolerances and does not impact mechanical fit or thermal performance.

Regulatory Compliance: Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring equivalent environmental and manufacturing process compatibility.

Supply Chain Advantage: The BNX005-11 maintains Active product status with documented inventory availability, eliminating obsolescence risk associated with the BNX005-01.

Temperature Range: The BNX005-11 extends the lower operating temperature limit to -40°C, providing enhanced performance margin for applications requiring extended temperature operation.

Frequently Asked Questions (FAQ)

Q: Can BNX005-11 be used as a direct replacement for BNX005-01 in existing designs?

A: Yes. The BNX005-11 is electrically and mechanically equivalent to the BNX005-01. Identical filter specifications, current rating, voltage rating, and package configuration ensure direct substitution without circuit redesign. The minor height difference (0.5mm) is within standard PCB assembly tolerances.

Q: What is the primary reason to substitute BNX005-01 with BNX005-11?

A: The BNX005-01 is classified as Obsolete, creating supply chain risk. The BNX005-11 is an Active product with documented inventory, ensuring long-term availability and manufacturing continuity.

Q: Are there any performance differences between these parts?

A: No performance differences exist in filter characteristics. Both parts provide identical attenuation, frequency response, and current handling. The BNX005-11 offers an extended lower temperature operating limit (-40°C vs. -30°C), which represents an operational advantage.

Q: Do both parts require identical PCB layout and mounting procedures?

A: Yes. Both parts use identical through-hole mounting with 4-lead block configuration. PCB footprint, lead spacing, and assembly procedures are equivalent. The 0.5mm height difference does not affect standard wave or reflow soldering processes.

Q: Are regulatory certifications equivalent?

A: Yes. Both parts maintain ROHS3 compliance and identical MSL ratings. No additional qualification or compliance documentation is required when substituting BNX005-11 for BNX005-01.

Q: What is the inventory status for each part?

A: BNX005-01 (Obsolete): 1807 pcs available. BNX005-11 (Active): 2630 pcs available. The BNX005-11 represents the recommended long-term supply source.
