MAX263BCWI+ Equivalent & Substitute Parts

Part Overview

The MAX263BCWI+ is a universal switched capacitor filter IC manufactured by Analog Devices Inc./Maxim Integrated. This 2nd order filter operates at a cutoff frequency of 57kHz and is designed for signal conditioning and filtering applications requiring precision analog filtering in compact form factors. The device is classified as Active product status with full RoHS3 compliance and REACH unaffected designation, making it suitable for current production environments. Alternative equivalent parts are identified to support supply chain continuity and design flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX263BCWI+ is determined by strict equivalence across the following critical parameters:

• Filter topology and type (Universal Switched Capacitor)
• Frequency specification (57kHz cutoff/center frequency)
• Filter order (2nd order)
• Number of independent filter channels (2)
• Supply voltage range compatibility (4.74V ~ 12.6V, ±2.37V ~ 6.3V)
• Package form factor (28-SOIC with 0.295" width, 7.50mm)
• Surface mount capability
• Compliance certifications (RoHS3, REACH unaffected)

Only parts meeting all these parameters without deviation are classified as direct equivalents. The MAX263BCWI+ represents the primary specification for this application requirement.

Parameter Comparison

Engineering Selection Recommendations

The MAX263BCWI+ maintains Active product status with full manufacturing support from Analog Devices Inc./Maxim Integrated. The device carries ROHS3 compliance certification and REACH unaffected status, confirming suitability for regulated manufacturing environments and export applications. The MSL rating of 1 (Unlimited) indicates minimal moisture sensitivity, reducing handling and storage constraints during assembly operations. Selection of this part number is supported by established supply chain availability and compliance documentation.

Frequently Asked Questions (FAQ)

Q: What defines a direct equivalent for the MAX263BCWI+?

A: Direct equivalence requires identical specifications across filter topology (Universal Switched Capacitor), frequency (57kHz), filter order (2nd), channel count (2), supply voltage range (4.74V ~ 12.6V, ±2.37V ~ 6.3V), package form factor (28-SOIC), and compliance certifications (RoHS3, REACH unaffected).

Q: Can the MAX263BCWI+ be substituted with parts having different frequency specifications?

A: No. The 57kHz cutoff frequency is a core functional parameter. Parts with alternative frequency ratings are not equivalent and will not perform the intended filtering function.

Q: Is the 28-SOIC package interchangeable with other package types?

A: No. The 28-SOIC (0.295", 7.50mm Width) package is a specific form factor. Alternative packages require PCB redesign and are not considered direct substitutes.

Q: What is the significance of the RoHS3 and REACH compliance markings?

A: RoHS3 compliance confirms the part meets European Union restrictions on hazardous substances. REACH unaffected status indicates the part is not subject to REACH authorization requirements. Both certifications are mandatory for regulated markets and supply chains.

Q: Does the MSL rating of 1 affect handling procedures?

A: MSL 1 (Unlimited) indicates the part has no moisture sensitivity limitations. Standard handling procedures for surface mount components apply without additional moisture control requirements.
