MAX267BCNG Band Pass Filter IC Equivalent & Substitute Parts

Part Overview

The MAX267BCNG is a band pass filter integrated circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for signal conditioning applications requiring 57kHz center frequency filtering. This device implements a 2nd order band pass filter topology in a 24-pin DIP package and operates across a dual supply voltage range of ±2.37V to ±6.3V or single supply of 4.74V to 12.6V.

The MAX267BCNG is classified as obsolete product status. Identifying equivalent substitute parts is necessary for ongoing system maintenance, design updates, and procurement continuity when original inventory becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX267BCNG is determined by strict equivalence across the following critical parameters:

• Filter Type: Band Pass
• Frequency - Cutoff or Center: 57kHz
• Filter Order: 2nd Order
• Number of Filters: 2
• Voltage - Supply: 4.74V ~ 12.6V, ±2.37V ~ 6.3V
• Mounting Type: Through Hole
• Package / Case: 24-DIP (0.300", 7.62mm)
• Supplier Device Package: 24-PDIP

The MAX267BCNG+ qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. Differences in product status, packaging format, and compliance certifications do not affect functional interchangeability in applications requiring the specified filter characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MAX267BCNG+ is the direct functional equivalent of the MAX267BCNG. Both parts share identical electrical and mechanical specifications for the 57kHz band pass filter application.

The MAX267BCNG+ offers the advantage of active product status, ensuring continued availability and manufacturing support. Additionally, the MAX267BCNG+ carries ROHS3 compliance, meeting current environmental and regulatory requirements for new designs and procurement cycles.

Selection between these parts should be based on system compliance requirements and supply chain considerations. The MAX267BCNG remains suitable for legacy system maintenance where RoHS compliance is not mandated. The MAX267BCNG+ is the preferred choice for new designs, system upgrades, and applications requiring regulatory compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can MAX267BCNG+ replace MAX267BCNG in existing applications?

A: Yes. The MAX267BCNG+ is electrically and mechanically identical to the MAX267BCNG. Both devices implement the same 2nd order band pass filter topology at 57kHz with identical supply voltage ranges and 24-PDIP package specifications. Direct substitution is supported without circuit modification.

Q: What is the difference between MAX267BCNG and MAX267BCNG+?

A: The primary differences are product status and compliance certifications. The MAX267BCNG is obsolete and RoHS non-compliant. The MAX267BCNG+ is an active product with ROHS3 compliance. Electrical performance and package specifications are identical.

Q: Are there packaging differences between these parts?

A: Both parts use the 24-DIP (0.300", 7.62mm) package with 24-PDIP supplier device package designation. The MAX267BCNG is supplied in standard packaging, while the MAX267BCNG+ is supplied in Tube packaging. Both are compatible with through-hole PCB assembly processes.

Q: Which part should be selected for new designs?

A: The MAX267BCNG+ is recommended for new designs. Active product status ensures manufacturing continuity and technical support. ROHS3 compliance meets current environmental regulations and simplifies procurement documentation for systems subject to regulatory requirements.

Q: Is the MAX267BCNG still available for legacy system support?

A: The MAX267BCNG remains available in limited inventory (1054 Pcs) for legacy system maintenance and repair applications. However, the MAX267BCNG+ with higher available inventory (1304 Pcs) and active status provides superior supply chain reliability for ongoing support needs.
