MAX267BENG Band Pass Filter IC Equivalent & Substitute Parts

Part Overview

The MAX267BENG 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 suitable for through-hole mounting.

The MAX267BENG is classified as obsolete product status. Identifying equivalent and substitute parts is necessary to support ongoing system maintenance, design updates, and procurement continuity where original components are no longer readily available or where active product alternatives offer improved compliance and availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX267BENG is determined by the following critical parameters that must remain constant across equivalent parts:

• Filter Type: Band Pass
• Frequency - Cutoff or Center: 57kHz
• Number of Filters: 2
• Filter Order: 2nd
• 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 MAX267BENG+ qualifies as a direct substitute based on identical electrical specifications, identical package configuration, and identical functional performance characteristics. The primary distinction between the main part and its substitute relates to product status classification and regulatory compliance posture.

Parameter Comparison

Engineering Selection Recommendations

The MAX267BENG+ is the direct substitute for MAX267BENG applications. Both parts share identical electrical performance, functional specifications, and physical package configuration.

Selection between these parts should be based on the following factors:

Product Status: The MAX267BENG is classified as obsolete, while MAX267BENG+ maintains active product status. Active status indicates ongoing manufacturer support, continued availability, and current production.

Regulatory Compliance: MAX267BENG+ achieves ROHS3 compliance, whereas MAX267BENG is RoHS non-compliant. Systems subject to RoHS directives or environmental regulations should prioritize MAX267BENG+ to ensure regulatory alignment.

Availability: MAX267BENG+ inventory is reported at 2100 pieces in stock compared to 1001 pieces for MAX267BENG, indicating superior supply chain availability for the substitute part.

Packaging: MAX267BENG+ is supplied in tube packaging, which may influence handling, storage, and integration into automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can MAX267BENG+ be used as a direct replacement for MAX267BENG in existing designs?

A: Yes. Both parts are electrically and functionally identical. They share the same filter specifications (57kHz center frequency, 2nd order band pass topology), supply voltage range, and 24-PDIP package configuration. No circuit modifications are required for substitution.

Q: What is the significance of the product status difference between obsolete and active?

A: Product status reflects manufacturer support lifecycle. Obsolete status indicates the part is no longer in active production. Active status confirms ongoing manufacturing, quality assurance, and availability. For new designs or long-term production requirements, active parts provide supply chain certainty.

Q: Does the RoHS3 compliance of MAX267BENG+ affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts deliver identical filter characteristics and voltage specifications.

Q: Are there any package or handling differences between MAX267BENG and MAX267BENG+?

A: MAX267BENG+ is supplied in tube packaging, while MAX267BENG packaging is not specified. Tube packaging is standard for through-hole components and facilitates automated handling. Both parts use identical 24-PDIP physical configuration suitable for through-hole PCB mounting.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution requires matching filter type (band pass), center frequency (57kHz), filter order (2nd), number of filters (2), supply voltage range (4.74V ~ 12.6V, ±2.37V ~ 6.3V), mounting type (through hole), and package configuration (24-DIP). MAX267BENG+ meets all these criteria.
