Substitute Part Grouping Explanation

Substitution of the ISO7230CDW is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following key areas:

  • Isolation voltage rating: 2500Vrms
  • Channel configuration: 3 channels, unidirectional
  • Data rate: 25Mbps minimum
  • Common Mode Transient Immunity: 25kV/µs minimum
  • Supply voltage range: 3.15V ~ 5.5V
  • Package type: 16-SOIC (0.295", 7.50mm Width)
  • Technology platform: Capacitive coupling
  • Operating temperature range: -40°C ~ 125°C

The ISO7230CDWR qualifies as a direct substitute based on complete parameter alignment across all electrical specifications and package requirements. The primary distinction is packaging format and product lifecycle status.

Engineering Selection Recommendations

The ISO7230CDWR is the direct substitute for the ISO7230CDW. Both parts are manufactured by Texas Instruments and share identical electrical specifications, performance characteristics, and compliance certifications. The ISO7230CDWR maintains Active product status, ensuring continued availability and manufacturing support, whereas the ISO7230CDW is in Last Time Buy status.

Selection of the ISO7230CDWR is appropriate for new designs and production continuity. Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements. The packaging difference—Tube for ISO7230CDW versus Cut Tape and Digi-Reel for ISO7230CDWR—reflects standard distribution formats and does not affect electrical or mechanical compatibility in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can ISO7230CDWR be used as a direct replacement for ISO7230CDW in existing designs?

A: Yes. The ISO7230CDWR is electrically and mechanically identical to the ISO7230CDW. All electrical parameters, timing specifications, isolation ratings, and package dimensions are equivalent. The parts are pin-compatible and functionally interchangeable.

Q: What is the difference between the Tube and Cut Tape packaging formats?

A: Tube packaging (ISO7230CDW) is typically used for lower-volume orders and manual assembly processes. Cut Tape and Digi-Reel packaging (ISO7230CDWR) is designed for automated pick-and-place assembly and higher-volume production. The components themselves are identical; only the delivery format differs.

Q: Why is ISO7230CDW in Last Time Buy status?

A: Last Time Buy status indicates that Texas Instruments is discontinuing production of this specific packaging variant. The ISO7230CDWR, with identical electrical specifications but in standard distribution packaging, represents the active product line continuation.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance, REACH Unaffected status, ECCN classification (EAR99), and HTSUS codes. Moisture Sensitivity Level (MSL 2, 1 Year) is identical for both variants.

Q: What supply chain considerations should be evaluated?

A: The ISO7230CDWR is in Active status with higher inventory availability (10,200 Pcs) compared to the ISO7230CDW (3,400 Pcs, Last Time Buy). For new production and long-term supply security, the ISO7230CDWR is the recommended selection.
