Substitute Part Grouping Explanation

Substitution for the DG413LDY-T1-E3 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

Switch circuit type: SPST - NO/NC
Number of circuits: 4
Multiplexer/Demultiplexer circuit: 1:1
Package / Case: 16-SOIC (0.154", 3.90mm Width)
Mounting type: Surface Mount
Operating temperature range: -40°C ~ 85°C (TA)

Performance Parameters Affecting Substitution:

On-state resistance (Ron): Determines signal integrity and power dissipation
Supply voltage ranges: Single (V+) and dual (V±) configurations
Switch time (Ton, Toff): Affects high-frequency performance
Charge injection and channel capacitance: Impact signal fidelity
Leakage current: Affects low-signal applications
Crosstalk performance: Critical for multi-channel isolation

Substitute parts are grouped by on-state resistance characteristics, as this parameter directly affects circuit performance and thermal behavior. Parts with lower Ron values (5Ohm) provide superior performance but may have different capacitance and leakage characteristics. Parts with higher Ron values (24Ohm to 45Ohm) trade performance for different supply voltage capabilities.

Engineering Selection Recommendations

Primary Recommendation: DG413LEDY-T1-GE3

The DG413LEDY-T1-GE3 is the manufacturer-recommended direct substitute from Vishay Siliconix. This part maintains the same base product family (DG413), identical package (16-SOIC), and operating temperature range (-40°C to 85°C). The part is active in production with ROHS3 compliance and MSL 1 rating. While on-state resistance increases from 17Ohm to 26Ohm and supply voltage ranges expand, this part is optimized for applications requiring the DG413 architecture with improved availability.

Secondary Recommendations by Application:

For applications requiring lower on-state resistance and improved signal integrity, the ADG453BRZ, ADG453BRZ-REEL, or ADG453BRZ-REEL7 (5Ohm) provide superior performance. These parts are active Analog Devices products with ROHS3 compliance. Supply voltage requirements must accommodate 12V single supply and ±4.5V to ±20V dual supply operation.

For applications with 12V or ±15V supply requirements and moderate on-state resistance, the ADG413BRZ, ADG413BRZ-REEL (35Ohm) or ADG433BRZ, ADG433BRZ-REEL (24Ohm) are active alternatives. The ADG433 variants offer faster switching times (90ns/60ns) compared to ADG413 variants (175ns/145ns).

For applications requiring extended supply voltage ranges (10V to 30V single supply), the DG413CY+ or DG413CY+T (45Ohm) provide compatibility with higher voltage systems. These parts are active with ROHS3 compliance but operate over a narrower temperature range (0°C to 70°C).

All substitute parts maintain 4-circuit SPST NO/NC configuration, 16-SOIC surface mount packaging, and MSL 1 moisture sensitivity rating. Selection should be based on specific supply voltage requirements, on-state resistance tolerance, and switching speed performance needed for the target application.

Frequently Asked Questions (FAQ)

Q: Can I directly replace DG413LDY-T1-E3 with DG413LEDY-T1-GE3?

A: Yes. Both parts share the same base product family (DG413), identical 16-SOIC package, and operating temperature range. The DG413LEDY-T1-GE3 is the active production equivalent with manufacturer recommendation. On-state resistance increases from 17Ohm to 26Ohm, and supply voltage ranges expand slightly. Circuit performance will be affected by the higher Ron value; verify that your application tolerates this change.

Q: What is the difference between ADG413BRZ and ADG413BRZ-REEL?

A: Both parts are electrically identical with 35Ohm on-state resistance and identical performance specifications. The difference is packaging: ADG413BRZ is supplied in Tube packaging, while ADG413BRZ-REEL is supplied in Cut Tape (CT) & Digi-Reel® format. Select based on your procurement and assembly requirements.

Q: Why do ADG453 variants have lower on-state resistance but higher charge injection?

A: The ADG453 family is optimized for low-impedance switching applications. The 5Ohm on-state resistance reduces signal attenuation and power dissipation. The trade-off is increased charge injection (20pC vs. 5pC) and higher channel capacitance (37pF vs. 5-9pF), which may affect high-frequency performance in sensitive applications.

Q: Can I use DG413CY+ or DG413CY+T in place of DG413LDY-T1-E3?

A: These parts share the DG413 base product family and 16-SOIC package but have significant differences. Operating temperature range is narrower (0°C to 70°C vs. -40°C to 85°C), on-state resistance is higher (45Ohm vs. 17Ohm), and supply voltage ranges differ substantially (10V to 30V single supply vs. 2.7V to 12V). Use only if your application meets these constraints.

Q: What does MSL 1 (Unlimited) moisture sensitivity mean?

A: MSL 1 indicates the lowest moisture sensitivity level. These parts can be stored indefinitely without special moisture control measures and do not require baking before reflow soldering. All listed substitute parts carry MSL 1 rating.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification, matching the original DG413LDY-T1-E3 compliance status.

Q: Which substitute offers the closest electrical match to DG413LDY-T1-E3?

A: The DG413LEDY-T1-GE3 offers the closest match within the same product family. For performance characteristics, the ADG433BRZ (24Ohm Ron) provides moderate on-state resistance between the original 17Ohm and higher-resistance alternatives, with faster switching times (90ns/60ns).
