MAX1480CCPI Equivalent & Substitute Parts

Part Overview

The MAX1480CCPI is a half-duplex RS422/RS485 transceiver IC manufactured by Analog Devices Inc./Maxim Integrated, housed in a 28-pin DIP package. This component is classified as obsolete, indicating that direct procurement from primary sources may be limited. Identifying equivalent and substitute parts ensures design continuity and supply chain reliability for applications requiring RS422/RS485 serial communication interfaces.

Substitute Part Grouping Explanation

Substitute parts for the MAX1480CCPI are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters:

Protocol compatibility: RS422/RS485 half-duplex operation
Electrical performance: 1/1 driver/receiver configuration, 250 kbps data rate, 70 mV receiver hysteresis
Power supply requirements: 4.5V ~ 5.5V operating range
Thermal specifications: 0°C ~ 70°C operating temperature range
Physical form factor: 28-DIP package with through-hole mounting

All substitute parts listed maintain identical electrical characteristics and package specifications. Differences exist only in product status (active vs. obsolete) and RoHS compliance certification levels.

Engineering Selection Recommendations

For applications currently using the obsolete MAX1480CCPI, the following active alternatives are available:

MAX1480BEPI+ is the preferred substitute, offering the highest current inventory (6,017 units) and ROHS3 compliance certification. This part maintains full electrical and mechanical compatibility with the original design.

MAX1480CCPI+ and MAX1480BCPI+ are secondary alternatives with equivalent specifications and ROHS3 compliance, though with lower inventory levels (2,200 units each).

MAX1480CEPI+ is available as a tertiary option with ROHS3 compliance and 1,376 units in stock.

All substitute parts are manufactured by the same supplier (Analog Devices Inc./Maxim Integrated) and carry identical electrical performance characteristics. Selection should prioritize inventory availability and supply chain lead times for your specific procurement timeline.

Frequently Asked Questions (FAQ)

Q: Can MAX1480BEPI+ directly replace MAX1480CCPI in existing designs?

A: Yes. Both parts share identical electrical specifications (RS422/RS485 half-duplex, 250 kbps data rate, 70 mV receiver hysteresis, 4.5V ~ 5.5V supply) and the same 28-DIP through-hole package. No circuit modifications are required.

Q: What is the difference between MAX1480CCPI and MAX1480CCPI+?

A: The primary difference is product status and RoHS compliance. MAX1480CCPI is obsolete and RoHS non-compliant, while MAX1480CCPI+ is active and ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All listed substitutes are supplied in 28-DIP through-hole packages. Packaging format (Tube) is consistent across active alternatives.

Q: Which substitute part should I select for new designs?

A: MAX1480BEPI+ is recommended for new designs due to superior inventory availability (6,017 units), active product status, and ROHS3 compliance certification.

Q: Do the substitute parts operate at the same data rate?

A: Yes. All substitute parts operate at 250 kbps, matching the original MAX1480CCPI specification.

Q: Are there any temperature range differences between the main part and substitutes?

A: No. All parts operate across the identical 0°C ~ 70°C temperature range.
