IL 710T-1E Digital Isolator Equivalent & Substitute Parts

Part Overview

The IL 710T-1E is a general purpose digital isolator manufactured by NVE Corp/Isolation Products, featuring GMR (Giant Magnetoresistive) technology with 2500Vrms isolation voltage and 1-channel unidirectional configuration. This component operates at data rates up to 110Mbps with 100kV/µs common mode transient immunity and is housed in an 8-MSOP surface mount package.

The IL 710T-1E has been discontinued at DiGi Electronics. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements. Substitute parts must maintain functional compatibility across isolation voltage, data rate, channel configuration, and package form factor.

Substitute Part Grouping Explanation

Substitute parts for the IL 710T-1E are classified into two categories based on functional compatibility:

Direct Manufacturer Substitute (Same Base Product): IL 710T-1ETR7 is a direct variant of the IL 710T-1E from the same manufacturer (NVE Corp/Isolation Products) and base product line (IL 710). This part maintains identical channel configuration, data rate, propagation delay, pulse width distortion, and rise/fall time specifications. The primary difference is packaging format (Tape & Reel vs. standard packaging) and reduced isolation voltage (800Vrms vs. 2500Vrms). This part is suitable for applications where 800Vrms isolation meets design requirements.

Similar Manufacturer Substitutes (Cross-Manufacturer Alternatives): HCPL-9000-300E, HCPL-9000-500, and HCPL-9000-500E are Broadcom Limited digital isolators that match the IL 710T-1E across critical electrical parameters: 2500Vrms isolation voltage, 1-channel unidirectional configuration, 110MBd data rate, identical propagation delay (15ns/15ns), pulse width distortion (3ns), and rise/fall time (1ns/1ns). These parts operate within the same supply voltage range (3V ~ 5.5V) and temperature range (-55°C to -40°C minimum, 125°C maximum). The primary differences are package form factor (8-SMD Gull Wing vs. 8-MSOP) and common mode transient immunity specification (15kV/µs vs. 100kV/µs).

Key Parameters Determining Substitution:

• Isolation voltage: 2500Vrms (primary criterion for cross-manufacturer substitutes)
• Number of channels: 1 (unidirectional)
• Data rate: 110Mbps/110MBd
• Propagation delay: 15ns maximum
• Supply voltage compatibility: 3V ~ 5.5V
• Package compatibility: Surface mount form factor
• RoHS compliance: ROHS3 Compliant

Parameter Comparison

Engineering Selection Recommendations

For Direct Manufacturer Continuity: IL 710T-1ETR7 is the preferred substitute when maintaining NVE Corp IsoLoop® technology is a design requirement. This part is currently active and available in higher inventory (2,846 pcs). It maintains identical electrical performance across data rate, propagation delay, and timing specifications. The reduced isolation voltage (800Vrms) is suitable for applications not requiring 2500Vrms isolation. The extended supply voltage range (2.7V minimum) provides additional design flexibility compared to the original part (3V minimum).

For Cross-Manufacturer Substitution with Full Isolation Voltage Compatibility: HCPL-9000-500E is the recommended Broadcom Limited alternative when 2500Vrms isolation voltage must be maintained and RoHS3 compliance is required. This part is currently active with 906 pcs in stock. It matches all critical electrical parameters: 2500Vrms isolation, 110MBd data rate, 15ns propagation delay, and 3ns pulse width distortion. The extended operating temperature range (-55°C to 125°C) exceeds the original specification. Package form factor differs (8-SMD Gull Wing vs. 8-MSOP), requiring PCB layout modification.

For RoHS Compliance Consideration: HCPL-9000-500 is not recommended due to RoHS non-compliance status. HCPL-9000-300E and HCPL-9000-500E both maintain ROHS3 compliance. HCPL-9000-300E is available in tube packaging (1,147 pcs inventory) and is suitable for lower-volume applications.

For Common Mode Transient Immunity Requirements: Applications requiring 100kV/µs CMTI must use IL 710T-1E or IL 710T-1ETR7. Broadcom HCPL-9000 series parts specify 15kV/µs CMTI, which is lower. This parameter difference must be evaluated against specific circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can IL 710T-1ETR7 directly replace IL 710T-1E in all applications?

A: IL 710T-1ETR7 is functionally compatible for applications where 800Vrms isolation voltage is sufficient. Both parts share identical data rate (110Mbps), propagation delay (15ns), pulse width distortion (3ns), and rise/fall time (1ns/1ns) specifications. The primary difference is isolation voltage rating. If your design requires 2500Vrms isolation, IL 710T-1ETR7 is not suitable. The extended supply voltage range (2.7V minimum vs. 3V minimum) is an additional benefit.

Q: What is the key difference between IL 710T-1E and HCPL-9000-500E?

A: Both parts provide 2500Vrms isolation voltage, 1-channel unidirectional configuration, and 110Mbps/110MBd data rate with identical propagation delay and pulse width distortion. The primary differences are: (1) Manufacturer (NVE Corp vs. Broadcom Limited), (2) Package form factor (8-MSOP vs. 8-SMD Gull Wing), (3) Common mode transient immunity (100kV/µs vs. 15kV/µs), and (4) Operating temperature range (-40°C to 125°C vs. -55°C to 125°C). Package differences require PCB layout redesign.

Q: Is HCPL-9000-500 suitable as a substitute?

A: HCPL-9000-500 matches all electrical specifications of IL 710T-1E and maintains the same 2500Vrms isolation voltage. However, this part is RoHS non-compliant, while IL 710T-1E is ROHS3 compliant. If RoHS3 compliance is a design or regulatory requirement, HCPL-9000-500 is not acceptable. HCPL-9000-500E is the RoHS3-compliant equivalent from the same Broadcom product line.

Q: Does package form factor affect electrical performance?

A: Package form factor (8-MSOP vs. 8-SMD Gull Wing) does not affect electrical performance specifications. However, it requires PCB layout modification, different footprint design, and potential changes to assembly processes. Electrical characteristics including isolation voltage, data rate, propagation delay, and timing remain identical across package variants.

Q: What is the significance of common mode transient immunity (CMTI) differences?

A: IL 710T-1E and IL 710T-1ETR7 specify 100kV/µs CMTI, while Broadcom HCPL-9000 series parts specify 15kV/µs CMTI. CMTI determines the isolator's ability to maintain signal integrity during rapid voltage transitions across the isolation barrier. Applications with high-speed switching or high dV/dt environments may require the higher 100kV/µs specification. Lower CMTI ratings are suitable for applications with slower voltage transitions.

Q: Are all substitute parts RoHS3 compliant?

A: No. HCPL-9000-500 is RoHS non-compliant. IL 710T-1E, IL 710T-1ETR7, HCPL-9000-300E, and HCPL-9000-500E are all ROHS3 compliant. If regulatory or design requirements mandate RoHS3 compliance, HCPL-9000-500 must be excluded from consideration.

Q: What inventory status should influence part selection?

A: IL 710T-1ETR7 has the highest inventory (2,846 pcs), followed by HCPL-9000-500E (906 pcs), HCPL-9000-300E (1,147 pcs), and HCPL-9000-500 (886 pcs). For long-term supply chain stability, IL 710T-1ETR7 offers the best availability. All substitute parts are currently active products, ensuring continued manufacturing support.

Q: Can I use HCPL-9000-300E instead of HCPL-9000-500E?

A: Yes, both parts are electrically equivalent. HCPL-9000-300E is packaged in tubes, while HCPL-9000-500E is supplied in Tape & Reel format. Both maintain ROHS3 compliance, 2500Vrms isolation, and identical electrical specifications. Selection depends on packaging requirements for your assembly process. HCPL-9000-300E may be more suitable for lower-volume or prototype applications.
