DG201HSDJ Equivalent & Substitute Parts

Part Overview

The DG201HSDJ is a 4-circuit SPST-NC (Single Pole Single Throw - Normally Closed) analog switch IC manufactured by Vishay Siliconix, housed in a 16-DIP package. This component features 50Ohm on-state resistance and operates across a supply voltage range of 13V to 36V (single supply) or ±7V to ±22V (dual supply). The DG201HSDJ is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. Substitute parts must maintain functional compatibility while meeting current manufacturing and compliance standards.

Substitute Part Grouping Explanation

Substitution of the DG201HSDJ is determined by the following critical parameters:

Mandatory Compatibility Criteria:

Switch circuit type: SPST - NC
Number of circuits: 4
Multiplexer/Demultiplexer circuit: 1:1
Package / Case: 16-DIP (0.300", 7.62mm)
Mounting type: Through Hole

Performance-Based Grouping: Substitute parts are grouped by on-state resistance (Ron), as this parameter directly affects signal integrity and insertion loss in analog switching applications. Parts with matching or lower Ron values maintain equivalent performance characteristics. Supply voltage ranges and switching speed parameters must be evaluated against application requirements.

Compliance Consideration: The DG201HSDJ is RoHS non-compliant and obsolete. Active substitute parts with ROHS3 compliance are preferred for new designs and long-term availability.

Engineering Selection Recommendations

Primary Substitutes (Matched Ron Performance):

ADG201HSKNZ and ADG201HSJNZ are the closest functional equivalents to the DG201HSDJ, both featuring 50Ohm on-state resistance with 1.5Ohm channel matching. Both are manufactured by Analog Devices Inc. and carry Active product status with ROHS3 compliance. ADG201HSKNZ offers faster switching times (50ns) compared to ADG201HSJNZ (75ns). Supply voltage ranges are narrower than the original part; applications requiring the full 13V to 36V single-supply range must be evaluated against the 10.8V to 16.5V specification of these alternatives.

Secondary Substitutes (Higher Ron, Active Status):

ADG201AKNZ (90Ohm), LTC201ACN#PBF (125Ohm), and ALD4211PCL (135Ohm) provide functional substitution with increased on-state resistance. These parts are suitable for applications where higher insertion loss is acceptable. All three carry Active product status and ROHS3 compliance. ALD4211PCL operates at the lowest supply voltages (3V to 12V single supply) and exhibits the lowest charge injection (0.2pC) and leakage current (100pA), making it suitable for low-power applications.

Avoid for New Designs:

MAX4511CPE+ and DG201ACJ+ are classified as Obsolete or have limited supply voltage specifications. While both carry ROHS3 compliance, MAX4511CPE+ is obsolete and DG201ACJ+ lacks single-supply voltage specification, limiting its applicability.

Frequently Asked Questions (FAQ)

Q: Can ADG201HSKNZ directly replace DG201HSDJ in existing designs?

A: ADG201HSKNZ maintains identical on-state resistance (50Ohm) and channel matching (1.5Ohm), with superior switching performance (50ns vs. 60ns/50ns). However, the supply voltage range is narrower (10.8V to 16.5V single supply vs. 13V to 36V). Verify that your application operates within the ADG201HSKNZ supply range before substitution.

Q: What is the impact of higher Ron values in substitute parts?

A: On-state resistance directly affects signal insertion loss and power dissipation. Parts with higher Ron (ADG201AKNZ at 90Ohm, LTC201ACN#PBF at 125Ohm) introduce greater attenuation in analog signal paths. Select substitutes based on your application's signal level and bandwidth requirements.

Q: Are all substitute parts RoHS compliant?

A: All listed substitute parts carry ROHS3 compliance. The original DG201HSDJ is RoHS non-compliant. For new designs and long-term production, ROHS3-compliant substitutes are required.

Q: Do substitute parts use the same 16-DIP package?

A: Yes. All substitute parts listed use the 16-DIP (0.300", 7.62mm) through-hole package, ensuring mechanical and electrical pin compatibility with the DG201HSDJ.

Q: Which substitute offers the best performance for low-power applications?

A: ALD4211PCL operates at the lowest supply voltages (3V to 12V single supply) with minimal charge injection (0.2pC) and leakage current (100pA). However, its 135Ohm on-state resistance is higher than the original part. Evaluate against your specific power budget and signal integrity requirements.

Q: What is the difference between ADG201HSKNZ and ADG201HSJNZ?

A: Both parts feature identical on-state resistance (50Ohm) and channel matching (1.5Ohm). ADG201HSKNZ offers faster switching times (50ns) compared to ADG201HSJNZ (75ns). Select based on your application's timing requirements.
