DS26LS31MJ/883 Equivalent & Substitute Parts

Part Overview

The DS26LS31MJ/883 is a 4/0 Driver RS422 interface IC manufactured by Texas Instruments in a 16-CDIP through-hole package. This component is classified as an active product with full production support. The device operates across an extended temperature range of -55°C to 125°C and is compliant with ROHS3 standards. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility allow direct replacement in circuit applications, particularly when addressing inventory availability, packaging preferences, or specific operational requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS26LS31MJ/883 is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Number of Drivers/Receivers configuration: 4/0
• Supply voltage range: 4.5V ~ 5.5V
• Interface protocol classification: RS422 driver functionality
• Through-hole mounting requirement

Mechanical Compatibility Criteria:

• Package footprint: 16-pin DIP family (0.300" pitch, 7.62mm width)
• Pin count: 16 pins
• Through-hole mounting type

Compliance & Certification:

• RoHS3 compliance status
• ECCN and HTSUS classifications

The AM26C31IN meets the electrical driver configuration (4/0), supply voltage (4.5V ~ 5.5V), and mechanical package family (16-DIP) requirements. Both parts share identical ECCN and HTSUS codes, confirming regulatory equivalence. The primary distinction is the operating temperature range and packaging format.

Parameter Comparison

Engineering Selection Recommendations

DS26LS31MJ/883 Selection Criteria:

• Applications requiring extended operating temperature range (-55°C to 125°C)
• Environments with unlimited moisture sensitivity requirements
• CDIP ceramic package preference for thermal or reliability specifications
• Military or aerospace grade component requirements

AM26C31IN Selection Criteria:

• Commercial and industrial applications within -40°C to 85°C operating range
• Standard plastic DIP package acceptable for application requirements
• Tube packaging format preferred for automated assembly processes
• Cost-optimized procurement for standard temperature range applications

Both parts maintain active product status with full manufacturer support and identical regulatory compliance (ROHS3, EAR99, HTSUS 8542.39.0001). Selection between these parts is determined by operating temperature requirements and package material specifications rather than electrical functionality.

Frequently Asked Questions (FAQ)

Q: Can AM26C31IN directly replace DS26LS31MJ/883 in all applications?

A: Direct replacement is valid only for applications operating within the -40°C to 85°C temperature range. The DS26LS31MJ/883 supports extended temperature operation to -55°C and 125°C. If your application requires these extended limits, AM26C31IN is not suitable.

Q: What is the difference between CDIP and DIP packaging?

A: CDIP (Ceramic DIP) uses ceramic material for the package body, while DIP (Plastic DIP) uses plastic. Both maintain identical 0.300" pitch and 16-pin configuration. CDIP typically offers superior thermal performance and is preferred in high-reliability applications. DIP is standard for commercial applications.

Q: Are the pin configurations identical between these parts?

A: Both parts are 16-pin through-hole packages with 0.300" (7.62mm) pitch. Pin-to-pin compatibility is confirmed by the matching 4/0 driver/receiver configuration and identical supply voltage requirements.

Q: Do both parts support RS422 protocol?

A: The DS26LS31MJ/883 is explicitly specified as RS422 protocol. The AM26C31IN protocol specification is not provided in the available data. Verify AM26C31IN protocol compatibility with the manufacturer datasheet before substitution.

Q: What is the significance of MSL rating differences?

A: DS26LS31MJ/883 has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. AM26C31IN lists MSL as Not Applicable, suggesting standard plastic package handling procedures apply. This does not affect electrical performance but may impact storage and handling protocols.

Q: Are both parts RoHS3 compliant?

A: Yes, both DS26LS31MJ/883 and AM26C31IN are ROHS3 compliant and share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.
