ISO7830FDW Digital Isolator - Equivalent & Substitute Parts

Part Overview

The ISO7830FDW is a general purpose digital isolator manufactured by Texas Instruments, featuring 5700Vrms isolation voltage across 3 channels with 100Mbps data rate capability. This component is designed for applications requiring galvanic isolation in industrial, automotive, and communication systems. The part is currently in active production status with robust inventory availability (793 pcs in tube packaging). Alternative part numbers may be required due to packaging format differences, supply chain considerations, or specific procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

The ISO7831FDW qualifies as a parametric equivalent to the ISO7830FDW based on identical electrical and mechanical specifications. Both parts share the same core technical parameters: 5700Vrms isolation voltage, 3-channel configuration, 100Mbps data rate, 70kV/µs CMTI, identical propagation delay characteristics, and 16-SOIC package format. The primary distinction between these parts is packaging format: ISO7830FDW is supplied in tube packaging, while ISO7831FDW is supplied in bulk packaging. Both parts maintain identical performance characteristics, compliance certifications (ROHS3, REACH Unaffected), and moisture sensitivity levels (MSL 2, 1 Year). Substitution is valid when packaging format requirements permit bulk supply instead of tubed components.

Parameter Comparison

Engineering Selection Recommendations

Both ISO7830FDW and ISO7831FDW are active production components with full ROHS3 compliance and REACH unaffected status, making them suitable for regulated applications. Selection between these parts should be based on procurement packaging requirements and supply chain logistics. The ISO7831FDW offers significantly higher inventory availability (100400 pcs bulk vs. 793 pcs tubed), making it preferable for high-volume production runs where bulk packaging is acceptable. The ISO7830FDW remains the appropriate choice when tube packaging is mandated by assembly processes or quality control procedures. Both parts maintain identical electrical performance and thermal characteristics across the full operating temperature range (-55°C to 125°C), ensuring functional interchangeability in circuit design.

Frequently Asked Questions (FAQ)

Q: Can ISO7831FDW replace ISO7830FDW in production? A: Yes, provided your assembly process accepts bulk packaging format. All electrical parameters, thermal ratings, and compliance certifications are identical between the two parts.

Q: What is the primary difference between these part numbers? A: The only difference is packaging format. ISO7830FDW is supplied in tube packaging; ISO7831FDW is supplied in bulk packaging. Electrical specifications and performance characteristics are identical.

Q: Are there any performance differences between tubed and bulk packaged versions? A: No. Packaging format does not affect component performance, electrical characteristics, or reliability. Both versions meet identical specifications for isolation voltage, data rate, propagation delay, and operating temperature range.

Q: Which part should I specify for high-volume applications? A: ISO7831FDW is recommended for high-volume production due to superior inventory availability and bulk packaging efficiency. Confirm your assembly process can accommodate bulk packaging format.

Q: Do both parts have the same moisture sensitivity level? A: Yes. Both ISO7830FDW and ISO7831FDW carry MSL 2 rating with 1-year shelf life under controlled conditions.

Q: Are there any compliance or certification differences? A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN and HTSUS classifications.
