Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ISO7830DWR is determined by strict equivalence across the following critical parameters:

• Channel Configuration: 3 channels with 2/1 input distribution (Side 1/Side 2)
• Isolation Voltage: 5700Vrms minimum
• Data Rate: 100Mbps
• Common Mode Transient Immunity: 70kV/µs minimum
• Package Type: 16-SOIC (0.295", 7.50mm Width) surface mount
• Supply Voltage Range: 2.25V ~ 5.5V
• Operating Temperature Range: -55°C ~ 125°C
• Technology: Capacitive coupling architecture
• Compliance: ROHS3 compliant, REACH unaffected

The ISO7831FDWR meets all specified parameters and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the ISO7830DWR and ISO7831FDWR are active production components from Texas Instruments with identical electrical and mechanical specifications. Selection between these parts is based on availability and procurement requirements:

• ISO7830DWR: Primary selection with higher inventory availability (21,596 pcs in stock)
• ISO7831FDWR: Qualified substitute with adequate inventory (4,398 pcs in stock)

Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The identical parametric specifications ensure direct functional interchangeability in circuit designs without modification to PCB layout or firmware.

Frequently Asked Questions (FAQ)

Q: Can ISO7831FDWR be used as a direct replacement for ISO7830DWR?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications, including isolation voltage, data rate, CMTI, propagation delay, supply voltage range, operating temperature, and package configuration. No circuit modifications are required.

Q: Are there any differences in the 16-SOIC package between these parts?

A: No. Both parts use the identical 16-SOIC (0.295", 7.50mm Width) surface mount package with the same pinout and mechanical dimensions. PCB footprints are interchangeable.

Q: What determines substitution eligibility for ISO7830DWR?

A: Substitutes must match all critical parameters: 3-channel configuration, 5700Vrms isolation, 100Mbps data rate, 70kV/µs CMTI, 16-SOIC package, 2.25V–5.5V supply range, -55°C to 125°C operating temperature, and capacitive coupling technology.

Q: Do both parts have the same compliance certifications?

A: Yes. Both ISO7830DWR and ISO7831FDWR are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings of 2 (1 Year).

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability and supplier lead times. Both maintain active production status with equivalent long-term availability.
