MAX295C/D Equivalent & Substitute Parts

Part Overview

The MAX295C/D is a Butterworth, Low Pass Switched Capacitor Filter IC featuring 8th order filtering at 50kHz cutoff frequency, supplied as a die package for surface mount applications. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and production continuity. The die package format limits direct integration options, requiring consideration of packaged alternatives that maintain electrical and functional equivalence.

Substitute Part Grouping Explanation

Substitution of the MAX295C/D is based on strict electrical and mechanical parameter matching:

Primary Substitution Criteria:

• Filter topology: Butterworth, Low Pass Switched Capacitor architecture
• Filter order: 8th order
• Cutoff frequency: 50kHz
• Supply voltage range: 4.75V ~ 11V, ±2.375V ~ 5.5V
• Surface mount capability
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The MAX295ESA+ qualifies as a direct substitute based on identical electrical specifications. The primary difference is packaging: the main part is supplied as a die, while the substitute is packaged in 8-SOIC format, enabling direct integration into standard PCB designs without additional packaging or hybridization steps.

Engineering Selection Recommendations

The MAX295ESA+ is the direct electrical equivalent to the MAX295C/D. Selection of this substitute is based on:

• Product Status: The MAX295C/D is obsolete, while MAX295ESA+ is active and available in production quantities (1216 pcs in stock versus 893 pcs for the obsolete die).
• Compliance Alignment: Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring regulatory and environmental consistency.
• Packaging Practicality: The 8-SOIC package of MAX295ESA+ provides standard PCB integration without requiring die-attach or hybrid assembly processes.
• Electrical Equivalence: All functional parameters—filter topology, order, frequency response, and supply voltage specifications—are identical.

Frequently Asked Questions (FAQ)

Q: Can MAX295ESA+ directly replace MAX295C/D in existing designs? A: Electrically, yes. The MAX295ESA+ provides identical filter performance. However, the packaging differs: MAX295C/D is a die requiring hybrid assembly, while MAX295ESA+ is a packaged 8-SOIC component suitable for standard PCB mounting. PCB layout and assembly processes must be adapted accordingly.

Q: Are the supply voltage specifications identical between these parts? A: Yes. Both parts operate across 4.75V ~ 11V and ±2.375V ~ 5.5V supply ranges, ensuring compatibility in existing power supply designs.

Q: What is the significance of the MSL rating for these components? A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity limitations. Standard storage and handling procedures apply without special desiccant or controlled environment requirements.

Q: Why is MAX295C/D listed as obsolete? A: The die format has been superseded by the packaged 8-SOIC version (MAX295ESA+), which provides equivalent functionality with improved integration and manufacturing efficiency for standard PCB applications.

Q: Are there any differences in RoHS compliance between these parts? A: No. Both parts are ROHS3 compliant, meeting identical environmental and regulatory standards.
