DS34C86TMX Equivalent & Substitute Parts

Part Overview

The DS34C86TMX is a 0/4 Receiver interface IC designed for RS422 and RS423 serial communication protocols, packaged in a 16-SOIC surface mount configuration. This part is classified as obsolete, which necessitates identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain identical electrical characteristics, protocol support, and mechanical compatibility to ensure seamless integration into existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS34C86TMX is determined by strict equivalence across the following critical parameters:

• Protocol compatibility: RS422 and RS423 support required
• Receiver configuration: 0/4 driver/receiver count
• Electrical specifications: 60 mV receiver hysteresis, 4.5V–5.5V supply voltage, -40°C to 85°C operating range
• Physical form factor: 16-SOIC package with identical 0.154" (3.90mm) width
• Surface mount compatibility: SOIC mounting type

All identified substitute parts meet these criteria and are classified as active products with current manufacturing status and RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the obsolete DS34C86TMX, the following selection criteria apply:

Direct Replacement (Preferred): DS34C86TMX/NOPB is the direct equivalent with identical electrical and mechanical specifications. This part carries the same base product number and represents the active production variant with RoHS3 compliance. Current inventory availability is 9,983 units.

Manufacturer-Recommended Alternative: AM26C32IDR is the manufacturer-recommended substitute, offering equivalent performance across all critical parameters. This part features a different base product number (AM26C32 versus DS34C86) but maintains full electrical and physical compatibility. Inventory availability is 22,800 units.

Parametric Equivalent: DS26C32ATMX/NOPB provides parametric equivalence with all specified electrical and mechanical characteristics. This variant represents an alternative product line within the same manufacturer portfolio. Inventory availability is 22,854 units.

All three substitute options are active products with RoHS3 compliance, addressing regulatory requirements that the original obsolete part does not meet.

Frequently Asked Questions (FAQ)

Q: Can DS34C86TMX be directly replaced with DS34C86TMX/NOPB? A: Yes. DS34C86TMX/NOPB is the active production equivalent with identical electrical specifications, receiver hysteresis, supply voltage range, operating temperature, and 16-SOIC package configuration. The primary difference is product status (active versus obsolete) and RoHS3 compliance.

Q: What is the difference between AM26C32IDR and DS26C32ATMX/NOPB? A: Both parts are parametric equivalents with identical receiver configuration (0/4), protocol support (RS422/RS423), hysteresis (60 mV), supply voltage (4.5V–5.5V), temperature range (-40°C to 85°C), and 16-SOIC packaging. The difference lies in base product numbering and internal design variants, though electrical performance is equivalent.

Q: Are all substitute parts available in the same packaging format? A: Yes. All substitute parts are supplied in 16-SOIC (0.154", 3.90mm width) surface mount packages with identical pin configurations and mechanical dimensions, ensuring direct PCB compatibility.

Q: Do substitute parts meet current regulatory requirements? A: All three substitute parts (DS34C86TMX/NOPB, AM26C32IDR, DS26C32ATMX/NOPB) are RoHS3 compliant. The original DS34C86TMX is RoHS non-compliant, making substitution necessary for applications subject to RoHS regulations.

Q: What is the moisture sensitivity level for substitute parts? A: All parts, including substitutes, carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
