Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISOW7841FAQDWERQ1 is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Isolation voltage: 5000Vrms
• Number of channels: 4
• Channel configuration: 3/1 unidirectional
• Data rate: 100Mbps
• Common mode transient immunity: 100kV/µs minimum
• Propagation delay: 17.6ns maximum (both tpLH and tpHL)
• Pulse width distortion: 4.7ns maximum
• Supply voltage range: 3V ~ 5.5V
• Operating temperature range: -40°C ~ 125°C
• Package type: 16-SOIC (0.295", 7.50mm Width)
• Technology: Capacitive coupling
• Automotive grade with AEC-Q100 qualification

Variable Parameters (Non-Critical for Substitution):

• Packaging format (Tape & Reel vs. Cut Tape & Digi-Reel)
• Inventory availability
• Specific suffix designations within the ISOW7841 base product family

All substitute parts listed maintain identical electrical performance and mechanical compatibility with the primary part number. Packaging format differences do not affect functional equivalence but may impact procurement and assembly processes.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed—ISOW7841AQDWERQ1, ISOW7841DWER, and ISOW7841FDWER—are direct parametric equivalents to the ISOW7841FAQDWERQ1. Each part maintains identical electrical specifications, mechanical compatibility, and automotive qualification status.

Selection Basis:

All substitute parts share the same base product number (ISOW7841) and are manufactured by Texas Instruments with active production status. Each part carries AEC-Q100 automotive qualification and ROHS3 compliance, meeting the same regulatory and environmental standards as the primary part number.

The primary distinction among these parts is packaging format. The ISOW7841FAQDWERQ1 is supplied in Tape & Reel (TR) format, while ISOW7841AQDWERQ1, ISOW7841DWER, and ISOW7841FDWER are supplied in Cut Tape (CT) & Digi-Reel® format. This difference affects procurement and assembly processes but does not impact functional performance or circuit-level compatibility.

Inventory availability varies across the substitute options, with ISOW7841FDWER currently showing the highest stock level (71,313 pieces), followed by ISOW7841DWER (36,600 pieces) and ISOW7841AQDWERQ1 (3,100 pieces). The primary part number ISOW7841FAQDWERQ1 has 937 pieces in stock.

Selection of any substitute part is appropriate for applications requiring the ISOW7841FAQDWERQ1, provided that the packaging format is compatible with the intended manufacturing process and assembly equipment.

Frequently Asked Questions (FAQ)

Q: Can ISOW7841AQDWERQ1, ISOW7841DWER, and ISOW7841FDWER be used interchangeably with ISOW7841FAQDWERQ1 in automotive applications?

A: Yes. All four part numbers are parametrically equivalent and carry identical AEC-Q100 automotive qualification. They share the same electrical specifications, isolation voltage, channel configuration, data rate, and operating temperature range. The only difference is packaging format (Tape & Reel versus Cut Tape & Digi-Reel), which does not affect circuit-level functionality or performance.

Q: What is the significance of the packaging format difference between Tape & Reel and Cut Tape & Digi-Reel?

A: Packaging format affects procurement and assembly processes. Tape & Reel (TR) format is optimized for high-volume automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel® format provides flexibility for lower-volume production or mixed-component assembly. The physical component itself—the 16-SOIC package dimensions and electrical performance—remains identical across all packaging formats.

Q: Are all substitute parts compliant with the same environmental and regulatory standards?

A: Yes. ISOW7841AQDWERQ1, ISOW7841DWER, and ISOW7841FDWER all carry ROHS3 compliance, REACH Unaffected status, and AEC-Q100 automotive qualification identical to the ISOW7841FAQDWERQ1. Moisture sensitivity level (MSL 3, 168 Hours) is consistent across all parts.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in isolation voltage (5000Vrms), number of channels (4), channel configuration (3/1 unidirectional), data rate (100Mbps), common mode transient immunity (100kV/µs), propagation delay (17.6ns maximum), pulse width distortion (4.7ns maximum), supply voltage range (3V ~ 5.5V), operating temperature range (-40°C ~ 125°C), and package type (16-SOIC). All listed substitutes meet these requirements.

Q: Can the ISOW7841DWER and ISOW7841FDWER be used in place of ISOW7841AQDWERQ1?

A: Yes. ISOW7841DWER and ISOW7841FDWER are parametrically equivalent to ISOW7841AQDWERQ1. All three parts share identical electrical specifications and automotive qualification. The suffix designations reflect internal Texas Instruments product line variations but do not indicate functional differences relevant to circuit design or performance.

Q: Is there a performance difference between the primary part number and its substitutes?

A: No. All substitute parts deliver identical electrical performance. Propagation delay, pulse width distortion, rise/fall time, common mode transient immunity, and all other timing and signal integrity parameters are equivalent across ISOW7841FAQDWERQ1, ISOW7841AQDWERQ1, ISOW7841DWER, and ISOW7841FDWER.

Q: What should be considered when selecting among the available substitute options?

A: Selection should be based on packaging format compatibility with assembly equipment and procurement requirements. ISOW7841FDWER offers the highest current inventory availability. All parts are active production items from Texas Instruments with equivalent lead times and supply reliability. Electrical and mechanical specifications are identical, so selection can be driven by supply chain and manufacturing process considerations.
