DG201HSDJ-E3 Equivalent & Substitute Parts

Part Overview

The DG201HSDJ-E3 is a 4-circuit SPST-NC analog switch manufactured by Vishay Siliconix, designed for signal routing and multiplexing applications. This through-hole 16-DIP component operates across a wide supply voltage range (13V to 36V single supply, or ±7V to ±22V dual supply) with 50Ohm on-state resistance and fast switching characteristics. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating.

Equivalent and substitute parts are necessary when the original DG201HSDJ-E3 becomes unavailable, when design requirements demand different electrical performance characteristics, or when alternative manufacturers' components offer improved specifications or better inventory availability.

Engineering Selection Recommendations

Primary Recommendation: ADG201HSJNZ

The ADG201HSJNZ from Analog Devices Inc. is the closest functional equivalent to the DG201HSDJ-E3. It maintains identical on-state resistance (50Ohm) and channel-to-channel matching (1.5Ohm), ensuring signal integrity equivalent to the original design. Operating temperature range extends to -40°C to 85°C, matching the original specification. The part is currently in active production status with full RoHS3 compliance and REACH unaffected certification. Switch time performance (75ns) is marginally slower than the original (60ns/50ns) but remains suitable for most analog switching applications.

Secondary Recommendation: ADG201AKNZ

The ADG201AKNZ offers active production status and extended inventory availability (2409 units). This part is suitable for applications where on-state resistance of 90Ohm is acceptable. It maintains the same operating temperature range (-40°C to 85°C) and RoHS3 compliance. Channel-to-channel matching of 4.5Ohm introduces slightly higher resistance variation compared to the original 1.5Ohm specification. Supply voltage range is more restricted (10V to 15V single supply) than the original design.

Alternative for Extended Supply Voltage Range: MAX4511CPE+

The MAX4511CPE+ supports the widest single supply voltage range (9V to 36V), matching the original DG201HSDJ-E3 upper limit. However, this part carries obsolete product status and should only be selected if extended supply voltage compatibility is critical and no alternative meets the application requirement. Leakage current performance (500pA) is superior to all other options.

Not Recommended: DG201ACJ+ and LTC201ACN#PBF

Both parts operate within restricted temperature ranges (0°C to 70°C), eliminating them from applications requiring the original -40°C to 85°C specification. DG201ACJ+ exhibits significantly higher on-state resistance (200Ohm) and slower switching times (600ns/450ns). LTC201ACN#PBF is limited to fixed supply voltages (5V single or ±15V dual) with no range flexibility.

Frequently Asked Questions (FAQ)

Q: Can ADG201HSJNZ be used as a direct drop-in replacement for DG201HSDJ-E3?

A: Yes, for most applications. Both parts share identical 16-DIP package dimensions, through-hole mounting, 50Ohm on-state resistance, and 1.5Ohm channel-to-channel matching. The ADG201HSJNZ operates across -40°C to 85°C, matching the original temperature range. Verify that your application's supply voltage requirements fall within the ADG201HSJNZ range (10.8V to 16.5V single supply, or ±14.6V to ±16.5V dual supply). Switch time is slightly longer (75ns vs. 60ns/50ns), which is acceptable for most signal routing applications but should be verified for high-speed switching requirements.

Q: What is the primary difference between the substitute parts?

A: The substitute parts differ primarily in on-state resistance (50Ohm to 200Ohm), supply voltage operating ranges, and switching speed. ADG201HSJNZ and the original DG201HSDJ-E3 both feature 50Ohm resistance and tight channel matching (1.5Ohm), making them functionally equivalent. ADG201AKNZ increases resistance to 90Ohm but maintains the same temperature range. DG201ACJ+, LTC201ACN#PBF, and MAX4511CPE+ offer higher resistance values (125Ohm to 200Ohm) and are suitable only when the application can tolerate increased on-state resistance and slower switching times.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts carry RoHS3 compliance certification. The DG201HSDJ-E3, ADG201AKNZ, ADG201HSJNZ, DG201ACJ+, LTC201ACN#PBF, and MAX4511CPE+ are all ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity).

Q: Which substitute part has the best leakage current performance?

A: The MAX4511CPE+ exhibits the lowest leakage current at 500pA (IS(off) max). The original DG201HSDJ-E3 and ADG201HSJNZ both specify 1nA leakage current. ADG201AKNZ specifies 2nA, while DG201ACJ+ and LTC201ACN#PBF both specify 5nA. For low-leakage applications, MAX4511CPE+ is superior, but its obsolete status should be considered.

Q: Can I use a substitute part with higher on-state resistance?

A: Higher on-state resistance increases signal attenuation and power dissipation in the switch. DG201ACJ+ (200Ohm) and MAX4511CPE+ (160Ohm) are suitable only if your application design accounts for increased insertion loss. Verify that signal levels remain within acceptable limits and that thermal dissipation is adequate. For low-impedance signal routing, maintain on-state resistance at or below 90Ohm (ADG201AKNZ).

Q: What is the impact of different supply voltage ranges?

A: The original DG201HSDJ-E3 operates from 13V to 36V (single supply) or ±7V to ±22V (dual supply). ADG201HSJNZ operates from 10.8V to 16.5V (single) or ±14.6V to ±16.5V (dual), which is more restrictive. If your circuit operates at the extremes of the original range (below 10.8V or above 16.5V single supply), ADG201HSJNZ is not suitable. MAX4511CPE+ supports 9V to 36V single supply, matching the original upper limit. Verify your actual operating voltage before selecting a substitute.

Q: Is package compatibility guaranteed across all substitute parts?

A: Yes, all substitute parts use identical 16-DIP (0.300", 7.62mm) through-hole packaging. PCB footprints and socket compatibility are identical. No layout modifications are required for mechanical substitution.
