Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX1488ECPD+ is determined by the following critical parameters:

Primary Substitution Criteria:

• Protocol: RS232
• Number of Drivers/Receivers: 4/0 configuration
• Package / Case: 14-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• RoHS Status: ROHS3 Compliant

Secondary Compatibility Factors:

• Voltage Supply Range (must encompass or overlap with 4.5V ~ 13.2V)
• Operating Temperature Range (must support 0°C ~ 70°C minimum)
• Data Rate capability (120 Kbps or higher)

All substitute parts listed maintain the identical package footprint, pin configuration, and RS232 protocol specification. Voltage supply ranges and operating temperature specifications vary among substitutes; however, each substitute supports the operational envelope of the primary part within its specified limits.

Engineering Selection Recommendations

Primary Selection (Active Product): MAX1488ECPD+ remains the preferred choice for new designs due to its active product status and unlimited moisture sensitivity level (MSL 1). This part is suitable for standard commercial applications within the 0°C ~ 70°C operating range.

Secondary Selection (Last Time Buy Status): SN75C188N, MC1488N, and SN75188N are classified as Last Time Buy products. These parts are functionally equivalent and pin-compatible but have limited availability windows. Selection among these three substitutes depends on specific application requirements:

• SN75C188N: Supports ±4.5V ~ 15V supply range with 0°C ~ 70°C operating temperature. Suitable for applications requiring extended positive and negative supply voltage tolerance.

• MC1488N: Supports ±7.5V ~ 15V supply range with extended operating temperature range (-55°C ~ 125°C). Appropriate for industrial or temperature-critical applications.

• SN75188N: Supports ±7.5V ~ 15V supply range with 0°C ~ 70°C operating temperature. Provides balanced voltage and temperature specifications for general-purpose RS232 driver applications.

All substitute parts maintain ROHS3 compliance and are suitable for direct pin-for-pin replacement within the specified electrical operating parameters.

Frequently Asked Questions (FAQ)

Q: Can SN75C188N, MC1488N, or SN75188N be used as direct replacements for MAX1488ECPD+?

A: Yes. All three parts are pin-compatible 4/0 RS232 drivers in 14-DIP packages. Each substitute maintains the same pinout and functional protocol. Voltage supply ranges and operating temperature specifications differ; verify that your application's power supply and thermal environment fall within the substitute part's rated limits.

Q: What is the difference between the voltage supply specifications?

A: MAX1488ECPD+ operates on 4.5V ~ 13.2V (single supply). SN75C188N, MC1488N, and SN75188N operate on ±7.5V ~ 15V or ±4.5V ~ 15V (dual supply). Confirm your circuit design uses compatible supply voltages before substitution.

Q: Why are some substitute parts marked as Last Time Buy?

A: Last Time Buy status indicates that the manufacturer has discontinued production and existing inventory represents the final available stock. These parts remain functionally equivalent but have limited procurement windows. For long-term production requirements, MAX1488ECPD+ (Active status) is recommended.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. MAX1488ECPD+, SN75C188N, MC1488N, and SN75188N are all ROHS3 compliant and suitable for applications requiring RoHS certification.

Q: Does operating temperature range affect substitution compatibility?

A: Operating temperature range does not prevent substitution but must be considered for application suitability. MC1488N supports -55°C ~ 125°C, making it suitable for extended temperature applications. MAX1488ECPD+, SN75C188N, and SN75188N support 0°C ~ 70°C, appropriate for commercial temperature ranges. Select the substitute based on your application's thermal requirements.

Q: Can I use these parts interchangeably in existing designs?

A: Pin-for-pin compatibility is confirmed across all parts. However, verify that your circuit's power supply voltage and operating temperature environment align with the selected substitute's specifications before implementation.
