Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCPL-0720#560 is determined by the following critical parameters:

• Voltage isolation rating: 3750Vrms (exact match required)
• Output configuration: Push-Pull, Totem Pole (exact match required)
• Number of channels: 1 (exact match required)
• Package / Case: 8-SOIC (0.154", 3.90mm Width) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Supply voltage range: 4.5V ~ 5.5V (exact match required)
• Output current: 10 mA (exact match required)
• Input type: Logic (exact match required)

Substitute parts may differ in the following parameters without affecting functional compatibility:

• Data rate (25MBd or lower acceptable)
• Common Mode Transient Immunity (20kV/µs acceptable, exceeds 10kV/µs minimum)
• Propagation delay (40ns maximum acceptable)
• Rise / Fall time (faster performance acceptable)
• Operating temperature range (extended range acceptable)
• Manufacturer identity
• Packaging format (Tape & Reel, Bulk, Tube acceptable)
• RoHS compliance status
• Product series designation

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and are functionally compatible with the HCPL-0720#560 based on critical electrical and mechanical parameters. Selection among substitutes should be based on the following criteria:

Data Rate Consideration: FOD0710 and FOD0710R2 operate at 12.5Mbps, which is half the data rate of the HCPL-0720#560 at 25MBd. These parts are suitable for applications where the lower data rate meets system requirements. FOD0720, FOD0720R2, FOD0721, and FOD0721R2 maintain the 25Mbps data rate and are direct functional equivalents.

RoHS Compliance: FOD0710R2, FOD0721, and FOD0721R2 are ROHS3 compliant. The original HCPL-0720#560 is RoHS non-compliant. Selection of RoHS-compliant alternatives is necessary for applications subject to RoHS regulations.

Operating Temperature Range: All substitute parts support -40°C to 100°C, extending the upper temperature limit by 15°C compared to the HCPL-0720#560 (-40°C to 85°C). This provides additional thermal margin in high-temperature environments.

Packaging Format: FOD0710R2 and FOD0721R2 are supplied in Tape & Reel format, matching the original part's packaging. FOD0710 and FOD0720 are supplied in Bulk format. FOD0721 is supplied in Tube format. Packaging selection depends on manufacturing process requirements and volume handling.

Manufacturer Availability: Fairchild Semiconductor supplies FOD0710, FOD0720, and FOD0720R2. onsemi supplies FOD0710R2, FOD0721, and FOD0721R2. Multi-source availability reduces supply chain risk.

Frequently Asked Questions (FAQ)

Q: Can FOD0710 or FOD0710R2 be used as direct replacements for HCPL-0720#560?

A: FOD0710 and FOD0710R2 are functionally compatible substitutes with identical isolation voltage, output configuration, package, and supply voltage. The primary difference is the reduced data rate of 12.5Mbps versus 25MBd. These parts are suitable for applications where the lower bandwidth meets system requirements. All other electrical and mechanical parameters are compatible.

Q: What is the difference between FOD0720 and FOD0720R2?

A: FOD0720 and FOD0720R2 are electrically identical. Both are manufactured by Fairchild Semiconductor and operate at 25Mbps with 3750Vrms isolation. The difference is packaging format: FOD0720 is supplied in Bulk, while FOD0720R2 is supplied in Bulk. Both maintain identical electrical performance and are interchangeable at the component level.

Q: Are onsemi FOD0721 and FOD0721R2 suitable replacements?

A: Yes. FOD0721 and FOD0721R2 are manufactured by onsemi and are electrically equivalent to the HCPL-0720#560. Both operate at 25Mbps with 3750Vrms isolation and identical output configuration. FOD0721 is supplied in Tube format, while FOD0721R2 is supplied in Tape & Reel format. Both are ROHS3 compliant. Selection depends on packaging requirements for your manufacturing process.

Q: Does the 20kV/µs Common Mode Transient Immunity in substitute parts affect compatibility?

A: No. The HCPL-0720#560 specifies a minimum of 10kV/µs CMTI. All substitute parts provide 20kV/µs CMTI, which exceeds the original specification. This represents improved performance and does not affect compatibility. Higher CMTI provides better noise immunity in high-speed switching environments.

Q: Can I use FOD0710R2 if my application requires 25Mbps operation?

A: No. FOD0710R2 operates at 12.5Mbps maximum data rate, which is insufficient for applications requiring 25Mbps operation. For 25Mbps applications, use FOD0720, FOD0720R2, FOD0721, or FOD0721R2.

Q: What is the impact of the extended operating temperature range in substitute parts?

A: Substitute parts support -40°C to 100°C operation, compared to the HCPL-0720#560 at -40°C to 85°C. This 15°C extension at the upper temperature limit provides additional thermal margin. If your application operates within the original -40°C to 85°C range, this difference has no impact. For applications approaching 85°C, the extended range provides design margin.

Q: Are all substitute parts pin-compatible with HCPL-0720#560?

A: Yes. All substitute parts use the 8-SOIC (0.154", 3.90mm Width) package with identical pinout. Pin-for-pin compatibility is maintained across all listed substitutes.

Q: Which substitute part should I select for new designs?

A: For new designs requiring 25Mbps operation with RoHS compliance, FOD0721R2 (onsemi, Tape & Reel) or FOD0710R2 (onsemi, Tape & Reel) are recommended based on data rate requirements. Both are ROHS3 compliant and available in standard manufacturing packaging. For applications requiring 12.5Mbps, FOD0710R2 provides equivalent performance with RoHS compliance.
