MAX250EPD+ Equivalent & Substitute Parts

Part Overview

The MAX250EPD+ is a full-duplex RS232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, designed for serial communication applications requiring bidirectional data transmission. This 14-pin DIP package device integrates 2 drivers and 2 receivers, operating across the standard 4.5V to 5.5V supply voltage range with a receiver hysteresis of 600 mV. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating, making it suitable for industrial and commercial applications. Equivalent parts are identified when electrical parameters, mechanical packaging, and functional specifications align within the allowed substitution criteria for RS232 transceiver applications.

Substitute Part Grouping Explanation

Substitution of RS232 transceiver components is determined by strict alignment of electrical and mechanical parameters. The MAX250EPD+ and MAX251EPD+ are grouped as parametric equivalents based on the following criteria:

Critical Substitution Parameters:

• Protocol: RS232 (identical)
• Number of Drivers/Receivers: 2/2 (identical)
• Duplex Mode: Full (identical)
• Receiver Hysteresis: 600 mV (identical)
• Supply Voltage Range: 4.5V ~ 5.5V (identical)
• Operating Temperature Range: -40°C ~ 85°C (identical)
• Package Type: 14-DIP (0.300", 7.62mm) (identical)
• Supplier Device Package: 14-PDIP (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)
• REACH Status: REACH Unaffected (identical)

Both parts share identical functional specifications, electrical characteristics, and physical packaging, establishing them as direct parametric equivalents suitable for interchangeable use in RS232 communication circuits.

Parameter Comparison

Engineering Selection Recommendations

Both MAX250EPD+ and MAX251EPD+ are active production components with identical electrical specifications, mechanical packaging, and regulatory compliance profiles. Selection between these parts is based on availability and inventory status rather than technical differentiation. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements for industrial and commercial applications. The 14-PDIP through-hole package format ensures compatibility with standard PCB layouts designed for DIP-based RS232 transceiver integration. Current inventory levels (MAX250EPD+: 1873 pcs; MAX251EPD+: 1762 pcs) support production requirements without technical constraints.

Frequently Asked Questions (FAQ)

Q: Can MAX251EPD+ be used as a direct replacement for MAX250EPD+ in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical characteristics, supply voltage requirements (4.5V ~ 5.5V), operating temperature range (-40°C ~ 85°C), receiver hysteresis (600 mV), driver/receiver configuration (2/2), and 14-PDIP package specifications. No circuit modifications are required.

Q: Are there any differences in pin configuration between MAX250EPD+ and MAX251EPD+?

A: No. Both parts use the identical 14-DIP (0.300", 7.62mm) package with 14-PDIP supplier device package designation, ensuring pin-for-pin compatibility.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both MAX250EPD+ and MAX251EPD+ are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL) ratings of 1 (Unlimited).

Q: What is the basis for substitution between these two part numbers?

A: Substitution is based on matching all critical electrical parameters (RS232 protocol, 2/2 driver/receiver configuration, full-duplex operation, 600 mV receiver hysteresis, 4.5V ~ 5.5V supply voltage, -40°C ~ 85°C operating temperature) and mechanical specifications (14-DIP through-hole package, 14-PDIP supplier package).

Q: Are both parts suitable for industrial temperature applications?

A: Yes. Both parts operate across the -40°C ~ 85°C temperature range, supporting industrial and commercial application requirements.
