IL 710-2B Digital Isolator Equivalent & Substitute Parts

Part Overview

The IL 710-2B is a general purpose digital isolator manufactured by NVE Corp/Isolation Products, utilizing Giant Magnetoresistive (GMR) technology. This component provides 2500Vrms isolation with single-channel unidirectional signal transmission at 110Mbps data rate, housed in an 8-DIP through-hole package. The IL 710-2B is classified as obsolete, necessitating identification of active equivalent and substitute parts for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility across isolation voltage, data rate, propagation delay, and supply voltage parameters while accommodating different packaging and mounting technologies.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IL 710-2B are qualified based on the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Isolation voltage: 2500Vrms (exact match required)
• Data rate: 110Mbps or 110MBd (equivalent specification)
• Propagation delay: 15ns maximum for both tpLH and tpHL
• Pulse width distortion: 3ns maximum
• Supply voltage range: 3V ~ 5.5V minimum compatibility
• Operating temperature: -55°C ~ 125°C
• Channel configuration: Single channel, unidirectional

Mechanical and Packaging Considerations:

• Through-hole 8-DIP package (IL 710-2B primary form factor)
• Surface-mount 8-SMD Gull Wing alternatives (HCPL-9000-300E, HCPL-9000-500, HCPL-9000-500E)
• Packaging format: Tube or Tape & Reel

Compliance and Status:

• Active product status preferred for new designs
• RoHS compliance status noted but not a substitution barrier
• REACH and ECCN classifications documented

The HCPL-9000 series from Broadcom Limited meets all electrical parameters with documented GMR technology equivalence. Differences in Common Mode Transient Immunity (15kV/µs versus 100kV/µs) reflect manufacturer specification variations but do not preclude functional substitution within the defined electrical envelope.

Parameter Comparison

Engineering Selection Recommendations

For Through-Hole PCB Designs: HCPL-9000 is the direct functional equivalent to IL 710-2B, maintaining identical 8-DIP through-hole package geometry and all critical electrical parameters. HCPL-9000 carries active product status from Broadcom Limited, ensuring long-term availability and supply chain continuity. This part is suitable for legacy board retrofits and designs requiring through-hole mounting technology.

For Surface-Mount PCB Designs: HCPL-9000-300E and HCPL-9000-500E are surface-mount alternatives with 8-SMD Gull Wing packaging. Both parts maintain electrical equivalence while offering RoHS3 compliance, addressing regulatory requirements for new product development. HCPL-9000-300E is packaged in Tube format; HCPL-9000-500E is supplied in Tape & Reel format suitable for automated assembly processes.

For Non-Compliant Applications: HCPL-9000-500 provides surface-mount functionality in Tape & Reel packaging without RoHS3 compliance, matching the RoHS non-compliant status of the original IL 710-2B where regulatory constraints do not apply.

Product Status Consideration: All Broadcom HCPL-9000 series variants maintain active product status, eliminating obsolescence risk associated with the IL 710-2B. Selection between variants depends on mounting technology requirements (through-hole versus surface-mount) and regulatory compliance mandates (RoHS3 requirement).

Frequently Asked Questions (FAQ)

Q: Can HCPL-9000 directly replace IL 710-2B in existing through-hole designs? A: Yes. HCPL-9000 maintains identical 8-DIP (0.300", 7.62mm) through-hole package geometry, isolation voltage (2500Vrms), data rate (110Mbps/110MBd), propagation delay (15ns), and operating temperature range (-55°C ~ 125°C). Pin-to-pin compatibility is established for direct substitution.

Q: What is the difference between HCPL-9000-300E and HCPL-9000-500E? A: Both parts are electrically identical with 8-SMD Gull Wing surface-mount packaging and RoHS3 compliance. The primary difference is packaging format: HCPL-9000-300E is supplied in Tube; HCPL-9000-500E is supplied in Tape & Reel. Selection depends on assembly process requirements and volume considerations.

Q: Why does IL 710-2B specify 100kV/µs CMTI while HCPL-9000 series specifies 15kV/µs? A: Common Mode Transient Immunity specifications reflect manufacturer measurement methodologies and design margins. Both values exceed typical application requirements for 2500Vrms isolation circuits. The lower HCPL-9000 specification does not indicate functional degradation within the defined electrical envelope.

Q: Is RoHS3 compliance required for IL 710-2B substitution? A: RoHS3 compliance is not a substitution requirement. HCPL-9000-300E and HCPL-9000-500E offer RoHS3 compliance for new designs subject to regulatory mandates. HCPL-9000 and HCPL-9000-500 maintain RoHS non-compliant status matching the original IL 710-2B for applications without compliance constraints.

Q: Can surface-mount HCPL-9000 variants be used in through-hole PCB designs? A: No. HCPL-9000-300E, HCPL-9000-500, and HCPL-9000-500E feature 8-SMD Gull Wing surface-mount packaging incompatible with through-hole PCB layouts. Through-hole designs require HCPL-9000 with 8-DIP package geometry.

Q: What is the inventory status for substitute parts? A: HCPL-9000: 1051 Pcs; HCPL-9000-300E: 1147 Pcs; HCPL-9000-500: 886 Pcs; HCPL-9000-500E: 906 Pcs. All variants are available as new original stock.

Q: Are there supply voltage compatibility considerations between IL 710-2B and HCPL-9000 series? A: All parts support 3V ~ 5.5V supply voltage range. IL 710-2B specifies dual ranges (3V ~ 5.5V and 4.5V ~ 5.5V); HCPL-9000 series specifies 3V ~ 5.5V. Designs operating within 3V ~ 5.5V envelope are fully compatible.
