IL 710-3 General Purpose Digital Isolator Equivalent & Substitute Parts

Part Overview

The IL 710-3 is a general purpose digital isolator manufactured by NVE Corp/Isolation Products, part of the IsoLoop® series. This component provides galvanic isolation using Giant Magnetoresistive (GMR) technology with a 2500Vrms isolation voltage rating, single unidirectional channel, and 110Mbps data rate capability. The IL 710-3 is classified as Active product status with surface mount 8-SOIC packaging.

Equivalent and substitute parts are identified based on matching electrical isolation specifications, channel configuration, data rate performance, and physical package compatibility. Substitution becomes necessary when the primary part number is unavailable, when alternative packaging formats are required for manufacturing processes, or when compliance certifications differ between procurement requirements.

Substitute Part Grouping Explanation

Substitute parts for the IL 710-3 are grouped into two categories based on substitution relationship type and electrical parameter alignment:

Direct Manufacturer Substitute (Same Manufacturer - NVE Corp): The IL 710-3E represents a direct substitute from the same manufacturer. This part maintains identical electrical specifications including 2500Vrms isolation voltage, 1 channel unidirectional configuration, 110Mbps data rate, 100kV/µs CMTI, and 8-SOIC package geometry. The primary difference is packaging format (Tube vs. standard packaging) and RoHS compliance status (ROHS3 Compliant vs. RoHS non-compliant).

Similar Manufacturer Substitutes (Cross-Manufacturer - Broadcom Limited): The HCPL-0900, HCPL-0900-000E, and HCPL-0900-500E represent similar substitutes from Broadcom Limited. These parts share the following matching parameters:

• 2500Vrms isolation voltage
• 1 channel unidirectional configuration
• 110MBd data rate (equivalent to 110Mbps)
• 15ns propagation delay (tpLH / tpHL)
• 3ns pulse width distortion
• 3V ~ 5.5V supply voltage range
• 8-SOIC package footprint
• GMR technology
• MSL 1 (Unlimited)

Key parameter differences in HCPL-0900 series: Common Mode Transient Immunity is 15kV/µs (lower than IL 710-3's 100kV/µs), and operating temperature range extends to -55°C ~ 125°C (wider than IL 710-3's -40°C ~ 100°C).

Substitution among HCPL-0900 variants is determined by packaging format: Tube (HCPL-0900, HCPL-0900-000E) or Tape & Reel (HCPL-0900-500E).

Parameter Comparison

Engineering Selection Recommendations

IL 710-3E Selection Criteria: The IL 710-3E is the preferred direct substitute when IL 710-3 availability is limited. This part maintains identical electrical performance and thermal operating range. Selection of IL 710-3E is appropriate when ROHS3 compliance is required for end-product certification, as IL 710-3E carries ROHS3 Compliant status while the original IL 710-3 is RoHS non-compliant. Tube packaging format of IL 710-3E is suitable for manual assembly or low-volume production workflows.

HCPL-0900 Series Selection Criteria: The HCPL-0900 series (HCPL-0900, HCPL-0900-000E, HCPL-0900-500E) represents cross-manufacturer substitutes from Broadcom Limited. These parts are electrically compatible for applications where the 100kV/µs CMTI specification of the IL 710-3 is not a design requirement. The HCPL-0900 series provides extended operating temperature range (-55°C ~ 125°C) suitable for industrial and automotive temperature environments.

Selection among HCPL-0900 variants is determined by manufacturing process requirements:

• HCPL-0900 (Tube packaging): Manual assembly or low-volume production
• HCPL-0900-000E (Tube packaging, ROHS3 Compliant): Manual assembly with RoHS compliance requirement
• HCPL-0900-500E (Tape & Reel, ROHS3 Compliant): Automated pick-and-place assembly with RoHS compliance requirement

Compliance Considerations: When RoHS3 compliance is mandatory, select IL 710-3E, HCPL-0900-000E, or HCPL-0900-500E. All three parts carry ROHS3 Compliant status. The original IL 710-3 and HCPL-0900 are RoHS non-compliant and should not be selected for applications requiring RoHS certification.

All substitute parts maintain identical MSL 1 (Unlimited) moisture sensitivity classification, eliminating moisture handling requirement changes during substitution.

Frequently Asked Questions (FAQ)

Q: Can IL 710-3E be used as a direct replacement for IL 710-3 in existing designs?

A: Yes. IL 710-3E maintains identical electrical specifications including 2500Vrms isolation voltage, 1 channel unidirectional configuration, 110Mbps data rate, 100kV/µs CMTI, 15ns propagation delay, and 8-SOIC package footprint. The primary difference is packaging format (Tube) and RoHS compliance status. No circuit redesign is required.

Q: What is the key electrical difference between IL 710-3 and HCPL-0900 series?

A: The primary electrical difference is Common Mode Transient Immunity (CMTI). IL 710-3 specifies 100kV/µs minimum CMTI, while HCPL-0900 series specifies 15kV/µs minimum CMTI. Applications requiring high-speed common mode transient rejection should retain IL 710-3 or IL 710-3E. Applications with lower CMTI requirements can substitute HCPL-0900 series parts.

Q: Are all substitute parts pin-compatible with IL 710-3?

A: Yes. All substitute parts (IL 710-3E, HCPL-0900, HCPL-0900-000E, HCPL-0900-500E) use identical 8-SOIC package with 0.154" (3.90mm) width. Pin configuration and footprint are compatible for direct PCB substitution without layout modification.

Q: Which substitute part should be selected for automated assembly?

A: HCPL-0900-500E is packaged in Tape & Reel (TR) format, optimized for automated pick-and-place assembly equipment. IL 710-3E, HCPL-0900, and HCPL-0900-000E are supplied in Tube packaging, suitable for manual assembly or semi-automated processes.

Q: Does substitution with HCPL-0900 series affect operating temperature range?

A: Yes. IL 710-3 and IL 710-3E operate from -40°C to 100°C. HCPL-0900 series operates from -55°C to 125°C, providing extended temperature range. For applications requiring operation below -40°C or above 100°C, HCPL-0900 series substitution extends the usable temperature envelope.

Q: What RoHS compliance status should be selected for new designs?

A: For new designs, select parts with ROHS3 Compliant status: IL 710-3E, HCPL-0900-000E, or HCPL-0900-500E. These parts meet current RoHS3 requirements. IL 710-3 and HCPL-0900 are RoHS non-compliant and should be reserved for legacy product support only.

Q: Can HCPL-0900 variants be substituted for each other?

A: Yes. HCPL-0900, HCPL-0900-000E, and HCPL-0900-500E are electrically identical. Substitution among these variants is determined by packaging format (Tube vs. Tape & Reel) and RoHS compliance requirement. All three maintain identical electrical performance and thermal specifications.
