DS3487M/NOPB Equivalent & Substitute Parts

Part Overview

The DS3487M/NOPB is a 4/0 Driver RS422/RS485 interface IC manufactured by Texas Instruments in a 16-SOIC package. This part is classified as Obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The DS3487M/NOPB operates within a 4.75V to 5.25V supply voltage range and is rated for 0°C to 70°C operating temperature. ROHS3 compliance and unlimited moisture sensitivity (MSL 1) provide environmental reliability for industrial and commercial applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the DS3487M/NOPB is determined by strict equivalence in the following critical parameters:

• Protocol: RS422/RS485 interface standard
• Number of Drivers/Receivers: 4/0 configuration
• Package / Case: 16-SOIC form factor (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Voltage - Supply: 4.75V ~ 5.25V nominal range
• Operating Temperature: 0°C ~ 70°C range
• RoHS Status: ROHS3 Compliant

Substitute parts are grouped into two categories: Active Status parts (recommended for new designs) and Last Time Buy/Obsolete parts (suitable for legacy system maintenance). All substitute parts maintain identical electrical specifications and package compatibility with the DS3487M/NOPB.

Parameter Comparison

Engineering Selection Recommendations

For new designs and production continuity, MC3487DR is the primary recommended substitute. This part is manufactured by Texas Instruments, maintains identical electrical and thermal specifications to the DS3487M/NOPB, and carries Active product status with full availability. MC3487DR is supplied in Cut Tape and Digi-Reel packaging, supporting both prototype and high-volume production workflows.

AM26LS31CDR provides an alternative Active substitute with equivalent specifications and is available in Cut Tape and Digi-Reel formats. Both MC3487DR and AM26LS31CDR are ROHS3 compliant with MSL 1 rating.

SN75ALS194DR offers Active status with Tape & Reel packaging for automated assembly processes. This part maintains full electrical equivalence within the 4.75V to 5.25V supply range and 0°C to 70°C operating temperature.

For extended operating temperature and supply voltage flexibility, ISL32172EIBZ and ISL32172EIBZ-T (Renesas Electronics) support 3V to 5.5V supply and -40°C to 125°C operating range with 32Mbps data rate capability. These parts are Active status and suitable for industrial and automotive applications requiring wider environmental specifications.

MAX3042BCSE+ (Analog Devices/Maxim Integrated) is an Active substitute with 20Mbps data rate and identical supply/temperature specifications to the DS3487M/NOPB.

Last Time Buy parts (AM26LS31CDRG4, SN75ALS194D, AM26LS31CD, MC3487D) are suitable for legacy system maintenance and repair but should not be selected for new production designs.

Frequently Asked Questions (FAQ)

Q: Can I use ISL32172EIBZ as a direct replacement for DS3487M/NOPB in a 5V system?

A: Yes. ISL32172EIBZ supports the 4.75V to 5.25V supply range required by the DS3487M/NOPB and maintains identical 4/0 driver/receiver configuration and 16-SOIC package. ISL32172EIBZ additionally supports 3V to 5.5V operation, providing broader supply flexibility. Operating temperature range differs (ISL32172EIBZ: -40°C to 125°C vs. DS3487M/NOPB: 0°C to 70°C), which is advantageous for extended environmental applications.

Q: What is the difference between MC3487DR and MC3487D?

A: Both parts are identical in electrical specification and package. MC3487DR is Active status with Cut Tape and Digi-Reel packaging for current production. MC3487D is Last Time Buy status in Tube packaging and should be used only for legacy system support.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification. All parts are also REACH Unaffected.

Q: What packaging options are available for Active substitute parts?

A: Active substitute parts are supplied in three packaging formats: Cut Tape & Digi-Reel (MC3487DR, AM26LS31CDR), Tape & Reel (SN75ALS194DR, ISL32172EIBZ-T), and Tube (ISL32172EIBZ, MAX3042BCSE+). Selection depends on assembly process requirements and order volume.

Q: Can I substitute DS3487M/NOPB with a part from a different manufacturer?

A: Yes. ISL32172EIBZ (Renesas) and MAX3042BCSE+ (Analog Devices/Maxim) are functionally equivalent substitutes. All substitute parts maintain RS422/RS485 protocol, 4/0 driver/receiver configuration, and 16-SOIC package compatibility. Verify data sheet specifications for any application-specific requirements before implementation.

Q: What is the inventory status of recommended substitutes?

A: MC3487DR has 162,933 units in stock. AM26LS31CDR has 38,110 units. SN75ALS194DR has 3,667 units. ISL32172EIBZ has 3,150 units. ISL32172EIBZ-T has 1,306 units. MAX3042BCSE+ has 2,135 units. All Active status parts maintain current production availability.
