IL 7710-3 Digital Isolator Equivalent & Substitute Parts

Part Overview

The IL 7710-3 is a general purpose digital isolator manufactured by NVE Corp/Isolation Products, utilizing Giant Magnetoresistive (GMR) technology. This component provides galvanic isolation of 2500Vrms for single-channel unidirectional signal transmission with a data rate of 110MBd and common mode transient immunity of 20kV/µs. The IL 7710-3 operates across a supply voltage range of 3V to 5.5V and is housed in an 8-SOIC surface mount package.

The IL 7710-3 is classified as obsolete. Locating equivalent or substitute components is necessary to support legacy system maintenance, design updates, or when original inventory becomes unavailable. Substitute parts must maintain functional compatibility across isolation voltage, channel configuration, data rate, and package specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IL 7710-3 is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Isolation voltage: 2500Vrms (exact match required)
• Number of channels: 1 channel (unidirectional)
• Package type: 8-SOIC (0.154", 3.90mm Width)
• Supply voltage range: 3V ~ 5.5V (compatible overlap required)
• Data rate: 110MBd or higher
• Propagation delay: 15ns maximum (tpLH and tpHL)
• Pulse width distortion: 3ns maximum

The IL 710-3 qualifies as a direct substitute. This part maintains identical isolation voltage, channel configuration, package specification, and propagation delay characteristics. The IL 710-3 offers enhanced common mode transient immunity (100kV/µs versus 20kV/µs) and an extended operating temperature range (-40°C ~ 100°C versus -40°C ~ 85°C). The IL 710-3 holds active product status, ensuring continued availability and support.

Parameter Comparison

Engineering Selection Recommendations

The IL 710-3 is the direct substitute for the obsolete IL 7710-3. Both components share identical electrical specifications for isolation voltage (2500Vrms), channel configuration (1 unidirectional channel), data rate (110MBd/Mbps), propagation delay (15ns maximum), and package form factor (8-SOIC).

The IL 710-3 provides operational advantages over the IL 7710-3:

Product Status: The IL 710-3 maintains active product status, ensuring long-term availability, manufacturing support, and technical documentation access. The IL 7710-3 is obsolete and subject to inventory depletion.

Common Mode Transient Immunity: The IL 710-3 specifies 100kV/µs minimum CMTI, compared to 20kV/µs for the IL 7710-3. This enhanced specification provides superior noise immunity in high-speed switching environments.

Operating Temperature Range: The IL 710-3 supports -40°C to 100°C operation, extending the upper temperature limit by 15°C relative to the IL 7710-3 (-40°C to 85°C). This broader range accommodates higher ambient or junction temperature applications.

Compliance: Both parts maintain identical RoHS non-compliance status, REACH unaffected classification, and MSL 1 moisture sensitivity rating. No compliance barriers exist to substitution.

For new designs or system updates, the IL 710-3 is the appropriate selection. For legacy system maintenance requiring exact functional equivalence, the IL 710-3 provides direct compatibility with performance enhancements.

Frequently Asked Questions (FAQ)

Q: Can the IL 710-3 directly replace the IL 7710-3 in existing designs?

A: Yes. The IL 710-3 maintains identical isolation voltage (2500Vrms), channel count (1), package type (8-SOIC), supply voltage range (3V ~ 5.5V), data rate (110MBd/Mbps), and propagation delay specifications (15ns maximum). Pin-to-pin compatibility and functional equivalence are confirmed. The IL 710-3 offers enhanced common mode transient immunity and extended operating temperature range.

Q: What is the difference between the IL 7710-3 and IL 710-3?

A: The primary differences are product status and performance specifications. The IL 7710-3 is obsolete; the IL 710-3 is active. The IL 710-3 specifies 100kV/µs common mode transient immunity versus 20kV/µs for the IL 7710-3, and supports operating temperatures to 100°C versus 85°C. All other electrical and mechanical specifications are identical.

Q: Are there package or pinout differences between these parts?

A: No. Both the IL 7710-3 and IL 710-3 use the 8-SOIC (0.154", 3.90mm Width) surface mount package. Pinout and mechanical dimensions are identical, enabling direct board-level substitution without layout modifications.

Q: What is the supply voltage compatibility?

A: Both parts operate across 3V to 5.5V supply voltage range. This specification is identical and ensures compatibility in systems designed for either component.

Q: Does the IL 710-3 meet the same compliance requirements as the IL 7710-3?

A: Yes. Both parts share identical RoHS non-compliance status, REACH unaffected classification, and MSL 1 (Unlimited) moisture sensitivity rating. Compliance profiles are equivalent.

Q: Why is the IL 7710-3 listed as obsolete?

A: The IL 7710-3 has been discontinued by NVE Corp/Isolation Products. The IL 710-3 represents the active product line continuation with equivalent functionality and enhanced specifications. Existing IL 7710-3 inventory is finite and subject to depletion.

Q: What is the data rate specification for these isolators?

A: Both parts specify 110MBd (IL 7710-3) and 110Mbps (IL 710-3) data rate. These specifications are functionally equivalent for digital isolation applications.

Q: Can the IL 710-3 handle higher common mode transient rates than the IL 7710-3?

A: Yes. The IL 710-3 specifies 100kV/µs minimum common mode transient immunity, compared to 20kV/µs for the IL 7710-3. The IL 710-3 provides superior performance in applications with rapid voltage transitions across the isolation barrier.
