SN65MLVD206DG4 Equivalent & Substitute Parts

Part Overview

The SN65MLVD206DG4 is a half-duplex LVDS multipoint transceiver manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This interface IC is designed for low-voltage differential signaling applications requiring 1/1 driver/receiver configuration with 200 Mbps data rate capability. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility for ongoing system support and new designs.

Engineering Selection Recommendations

For replacement of the discontinued SN65MLVD206DG4, the following selection hierarchy is based on product status and supply availability:

Primary Recommendation: SN65MLVD206D (Texas Instruments, Active status). This part is the direct successor with identical electrical and mechanical specifications, active manufacturing status, and highest inventory availability (2280 units). ROHS3 compliance and EAR99 export classification are maintained.

Secondary Recommendation: SN65MLVD201D (Texas Instruments, Active status). Parametrically equivalent with identical performance characteristics. Significantly higher inventory availability (650,300 units) provides superior long-term supply security. ROHS3 compliant with EAR99 export classification.

Tertiary Recommendation: SN65MLVD206BD (Texas Instruments, Active status). Functionally equivalent with active product status. Inventory availability of 1384 units supports medium-term requirements. ROHS3 compliant with EAR99 export classification.

Alternative Consideration: NB3N201SDG and NB3N206SDG (onsemi, Obsolete status). While electrically and mechanically equivalent, obsolete product status indicates discontinued manufacturing. These parts should be considered only when primary Texas Instruments alternatives are unavailable, and only for non-critical legacy system maintenance.

Frequently Asked Questions (FAQ)

Q: Can SN65MLVD206D directly replace SN65MLVD206DG4 without circuit modification?

A: Yes. Both parts share identical electrical specifications (LVDS multipoint protocol, 1/1 driver/receiver configuration, 200 Mbps data rate, 25 mV hysteresis, 3V–3.6V supply, -40°C to 85°C operating range) and mechanical package (8-SOIC, 0.154" width). Pin-for-pin compatibility is maintained.

Q: What is the difference between SN65MLVD206D and SN65MLVD201D?

A: Both parts are parametrically equivalent with identical electrical performance and package specifications. The primary difference is the base product number designation (206 vs. 201). SN65MLVD201D offers significantly higher inventory availability (650,300 units vs. 2280 units), making it preferable for high-volume production or long-term supply assurance.

Q: Why are the onsemi NB3N parts listed as obsolete?

A: NB3N201SDG and NB3N206SDG are marked as obsolete, indicating discontinued manufacturing by onsemi. While electrically and mechanically equivalent, obsolete status means no new production is available. These parts should only be sourced from existing inventory for legacy system support.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (SN65MLVD206D, SN65MLVD201D, SN65MLVD206BD, NB3N201SDG, NB3N206SDG) maintain ROHS3 compliance, meeting environmental and regulatory requirements for new designs and manufacturing.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All parts, including the original SN65MLVD206DG4 and all substitutes, have MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage, handling, or assembly.

Q: Can I use NB3N206SDG as a substitute for SN65MLVD206DG4?

A: Electrically and mechanically, yes. However, NB3N206SDG is obsolete, meaning no new production is available. Use only if existing inventory is accessible and only for legacy system maintenance. For new designs or ongoing production, select active-status Texas Instruments alternatives.
