MAX268AENG+ Equivalent & Substitute Parts Reference

Part Overview

The MAX268AENG+ is a programmable band pass filter IC manufactured by Analog Devices Inc./Maxim Integrated. This 24-DIP through-hole component provides second-order band pass filtering at 140kHz with dual filter channels and dual supply voltage capability (4.74V ~ 12.6V, ±2.37V ~ 6.3V). The device is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity rating. Finding equivalent parts is necessary when addressing supply chain constraints, inventory availability, or specific application requirements while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX268AENG+ is determined by strict equivalence across the following critical parameters:

Filter characteristics: Band pass topology, 2nd order, 140kHz center frequency, dual filter channels Electrical specifications: Supply voltage range 4.74V ~ 12.6V and ±2.37V ~ 6.3V Package specifications: 24-DIP through-hole form factor with 0.300" (7.62mm) pitch Compliance requirements: ROHS3 compliance, REACH unaffected status, MSL 1 rating Product status: Active manufacturing status

Only parts meeting all these parameters qualify as direct substitutes. No parameter relaxation or functional approximation is permitted.

Parameter Comparison

Engineering Selection Recommendations

The MAX268AENG+ maintains Active product status with full ROHS3 compliance and REACH unaffected classification, ensuring regulatory compliance for current and future applications. The unlimited MSL rating (MSL 1) eliminates moisture-related handling constraints during assembly and storage.

Selection of equivalent parts must prioritize exact parameter matching across all electrical and mechanical specifications. The 24-DIP through-hole package is a critical mechanical constraint for PCB compatibility. Supply voltage specifications must accommodate both single and dual supply configurations as specified.

Current inventory availability of 897 pieces supports immediate procurement without substitution necessity. When substitution becomes required, only parts with identical part numbers from the same manufacturer meet the strict equivalence criteria established for this product category.

Frequently Asked Questions (FAQ)

Q: Can the MAX268AENG+ be substituted with a different filter frequency? A: No. The 140kHz center frequency is a core functional specification. Parts with different frequency ratings are not equivalent and will not function identically in the application circuit.

Q: Are there alternative package options for the MAX268AENG+? A: The 24-DIP through-hole package is the specified form factor. Alternative packages (surface mount, different pin counts) are not direct substitutes and require circuit redesign.

Q: What is the significance of the dual supply voltage specification? A: The MAX268AENG+ supports both single supply (4.74V ~ 12.6V) and dual supply (±2.37V ~ 6.3V) configurations. Substitute parts must maintain this dual-mode capability.

Q: Does ROHS3 compliance affect substitution eligibility? A: Yes. All substitute parts must maintain ROHS3 compliance status to ensure regulatory alignment and material composition equivalence.

Q: Can the MAX268AENG+ be used in new designs? A: Yes. Active product status confirms ongoing manufacturing and support from Analog Devices Inc./Maxim Integrated, making it suitable for new design implementations.

Q: What does MSL 1 (Unlimited) mean for component handling? A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or assembly, simplifying logistics and manufacturing processes.
