HCPL-0723-560E Equivalent & Substitute Parts

Part Overview

The HCPL-0723-560E is a logic output optoisolator manufactured by Broadcom Limited, designed for high-speed digital isolation applications. This 3750Vrms isolation device operates at 50MBd data rate with push-pull, totem pole output configuration in an 8-SO Tall surface mount package. The part is currently active in production with full inventory availability (100,300 pcs in stock).

Substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits selection from alternative manufacturers offering equivalent electrical and mechanical specifications within the same isolation voltage class and output topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCPL-0723-560E is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Isolation voltage: 3750Vrms (exact match required)
• Output configuration: Push-Pull, Totem Pole (topology must match)
• Number of channels: 1 (single channel only)
• Output current capability: 10 mA per channel
• Supply voltage range: 4.5V ~ 5.5V (compatible range)
• Package footprint: 8-SOIC (0.154", 3.90mm Width) or 8-SO Tall (mechanically compatible)
• Input type: Logic
• Mounting type: Surface Mount

Allowable Variation Parameters:

• Data rate: Substitute parts may operate at lower data rates (12.5Mbps or 25Mbps) while maintaining compatibility with 50MBd applications
• Common Mode Transient Immunity: Substitute parts with equal or higher CMTI (≥10kV/µs) are acceptable
• Propagation delay: Substitute parts with equal or lower propagation delay are acceptable
• Operating temperature range: Substitute parts with equal or extended temperature range are acceptable
• Packaging format (Bulk, Tape & Reel, Tube): Interchangeable for component selection

The identified substitute parts (FOD0710, FOD0710R2, FOD0720, FOD0720R2, FOD0721, FOD0721R2) meet all critical matching parameters and are therefore electrically and mechanically compatible with the HCPL-0723-560E.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and comply with ROHS3 requirements where specified. Selection among FOD0710, FOD0710R2, FOD0720, FOD0720R2, FOD0721, and FOD0721R2 should be based on the following criteria:

Data Rate Compatibility: Applications requiring the full 50MBd capability of the HCPL-0723-560E will operate with FOD0720, FOD0720R2, FOD0721, and FOD0721R2 (25Mbps rated) at reduced but functional performance margins. FOD0710 and FOD0710R2 (12.5Mbps rated) are suitable only for applications with data rates at or below 12.5Mbps.

Temperature Range: The HCPL-0723-560E operates to 85°C maximum. All substitute parts extend operation to 100°C, providing additional thermal margin in applications with elevated ambient or junction temperatures.

Common Mode Transient Immunity: All substitute parts provide 20kV/µs CMTI, exceeding the 10kV/µs specification of the HCPL-0723-560E. This represents improved noise immunity in high-speed switching environments.

Packaging Format: FOD0710R2, FOD0721, and FOD0721R2 are available in Tape & Reel or Tube formats suitable for automated assembly. FOD0710 and FOD0720 are available in Bulk format. Selection should align with production assembly requirements.

Inventory Availability: FOD0710R2 (3,620 pcs), FOD0720 (5,394 pcs), FOD0720R2 (3,720 pcs), FOD0721 (1,923 pcs), and FOD0721R2 (3,820 pcs) provide alternative sourcing when HCPL-0723-560E availability is constrained.

Frequently Asked Questions (FAQ)

Q: Can FOD0710 or FOD0710R2 be used as a direct replacement for HCPL-0723-560E?

A: FOD0710 and FOD0710R2 are electrically and mechanically compatible substitutes. However, their 12.5Mbps data rate specification is lower than the HCPL-0723-560E 50MBd rating. These parts are suitable only for applications operating at or below 12.5Mbps. For applications requiring 50MBd operation, FOD0720, FOD0720R2, FOD0721, or FOD0721R2 are more appropriate selections.

Q: What is the difference between FOD0720 and FOD0720R2?

A: FOD0720 and FOD0720R2 are electrically identical with 25Mbps data rate and 3750Vrms isolation. The primary difference is packaging format: FOD0720 is supplied in Bulk format, while FOD0720R2 is supplied in Tape & Reel format. Selection depends on assembly process requirements.

Q: Are FOD0721 and FOD0721R2 interchangeable with HCPL-0723-560E?

A: Yes. FOD0721 and FOD0721R2 meet all critical electrical and mechanical parameters for substitution. Both operate at 25Mbps with 3750Vrms isolation, 10 mA output current, and 8-SOIC package footprint. FOD0721 is supplied in Tube format; FOD0721R2 is supplied in Tape & Reel format.

Q: Will substituting HCPL-0723-560E with a lower data rate part affect circuit performance?

A: Substitution with lower data rate parts (FOD0710 at 12.5Mbps or FOD0720/FOD0721 at 25Mbps) will not degrade circuit performance in applications operating below those rated speeds. The parts will function correctly at any data rate up to their specified maximum. For applications requiring the full 50MBd capability of the HCPL-0723-560E, lower-rated substitutes should not be used.

Q: Are all substitute parts ROHS3 compliant?

A: FOD0710R2, FOD0721, and FOD0721R2 are specified as ROHS3 compliant. FOD0710 and FOD0720 compliance status is not provided in the available specifications. FOD0720R2 compliance status is not specified. Verify ROHS3 compliance with the manufacturer or distributor if this certification is required for your application.

Q: What is the operating temperature range difference between HCPL-0723-560E and the substitute parts?

A: HCPL-0723-560E operates from -40°C to 85°C. All substitute parts (FOD0710, FOD0710R2, FOD0720, FOD0720R2, FOD0721, FOD0721R2) operate from -40°C to 100°C. This extended upper temperature limit provides additional thermal margin in high-temperature applications.

Q: Can I use FOD0710 in a 50MBd application?

A: FOD0710 is rated for 12.5Mbps operation. Using it in a 50MBd application exceeds its specified data rate capability and is not recommended. FOD0720, FOD0720R2, FOD0721, or FOD0721R2 (all rated for 25Mbps) are more suitable, though still below the 50MBd specification of the HCPL-0723-560E.
