ISO7760DBQR Equivalent & Substitute Parts

Part Overview

The ISO7760DBQR is a general purpose digital isolator manufactured by Texas Instruments, designed for high-voltage isolation applications requiring 3000Vrms isolation rating. This capacitive coupling isolator provides 6 unidirectional channels with 100Mbps data rate capability and operates across a wide temperature range of -55°C to 125°C. The device is currently in active production status and is ROHS3 compliant. Substitute parts are identified when inventory constraints or supply chain requirements necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISO7760DBQR are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Isolation voltage rating: 3000Vrms
• Channel count and configuration: 6 unidirectional channels (6 input / 0 output)
• Data rate: 100Mbps
• Common mode transient immunity: 85kV/µs minimum
• Supply voltage range: 2.25V ~ 5.5V
• Operating temperature range: -55°C ~ 125°C
• Package specification: 16-SSOP (0.154", 3.90mm Width)
• Technology platform: Capacitive coupling
• Propagation delay specifications: 16ns maximum (tpLH and tpHL)
• Pulse width distortion: 4.9ns maximum

The ISO7760FDBQR meets all these criteria and is classified as a parametric equivalent within the ISO776x series.

Parameter Comparison

Engineering Selection Recommendations

Both the ISO7760DBQR and ISO7760FDBQR are active production devices from Texas Instruments with identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and supply chain requirements. Both devices maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for industrial and commercial applications. The MSL rating of 2 (1 Year) applies uniformly across both parts, requiring standard moisture control during storage and handling. No technical differentiation exists between these devices based on the provided specifications.

Frequently Asked Questions (FAQ)

Q: Can ISO7760FDBQR be used as a direct replacement for ISO7760DBQR?

A: Yes. The ISO7760FDBQR is a parametric equivalent with identical electrical performance, isolation rating, channel configuration, data rate, timing specifications, supply voltage range, operating temperature range, and package specification. Direct substitution is supported without circuit modification.

Q: Are there any differences in compliance or certifications between these parts?

A: No. Both parts carry identical ROHS3 compliance, REACH unaffected status, EAR99 ECCN classification, and HTSUS code 8542.39.0001. MSL ratings are identical at level 2 (1 Year).

Q: What is the significance of the different part number suffixes (DBQR vs FDBQR)?

A: The suffix variation indicates different manufacturing date codes or production batches within the same product specification. Both parts conform to the identical ISO7760 base product specification and are functionally interchangeable.

Q: Are both parts available in the same packaging format?

A: Yes. Both ISO7760DBQR and ISO7760FDBQR are supplied in Cut Tape (CT) and Digi-Reel packaging formats with identical 16-SSOP package dimensions (0.154", 3.90mm Width).

Q: What are the critical parameters that define substitution eligibility for this product category?

A: Substitution eligibility is determined by matching isolation voltage (3000Vrms), channel count and configuration (6 unidirectional), data rate (100Mbps), CMTI rating (85kV/µs), supply voltage range (2.25V ~ 5.5V), operating temperature range (-55°C ~ 125°C), package type (16-SSOP), and timing specifications (propagation delay, pulse width distortion, rise/fall time).
