Substitute Part Grouping Explanation

Substitute parts for the HCPL-2231#500 are qualified based on strict equivalence across all electrical and mechanical parameters. The substitution logic is determined by the following criteria:

Electrical Parameters (Must Match Exactly):

• Voltage isolation rating: 3750Vrms
• Number of channels: 2
• Common mode transient immunity: 1kV/µs minimum
• Output configuration: Push-Pull, Totem Pole
• Current per channel: 25 mA
• Data rate: 5MBd
• Propagation delay specifications: 300ns maximum (both directions)
• Supply voltage range: 4.5V ~ 20V
• Operating temperature range: -40°C ~ 85°C

Mechanical Parameters (Must Match Exactly):

• Package type: 8-SMD, Gull Wing
• Mounting type: Surface Mount
• Base product number: HCPL-2231

Allowed Variations:

• Packaging format (Tape & Reel vs. Cut Tape & Digi-Reel)
• RoHS compliance status
• Inventory availability

The HCPL-2231-500E qualifies as a direct substitute because it maintains identical electrical performance and mechanical form factor while differing only in packaging format and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

Both the HCPL-2231#500 and HCPL-2231-500E are active production parts from Broadcom Limited with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

HCPL-2231#500 (Tape & Reel Packaging):

• Suitable for high-volume manufacturing environments with automated tape-fed assembly equipment
• RoHS non-compliant status may be relevant for applications without RoHS requirements
• Current inventory: 5100 pieces

HCPL-2231-500E (Cut Tape & Digi-Reel Packaging):

• Suitable for lower-volume production runs, prototyping, and manual assembly workflows
• ROHS3 compliant, meeting regulatory requirements for applications subject to RoHS directives
• Current inventory: 1410 pieces

Both parts maintain identical performance characteristics across all critical parameters including isolation voltage, data rate, propagation delay, and output current specifications. The choice between them depends on manufacturing process requirements and compliance obligations rather than functional capability.

Frequently Asked Questions (FAQ)

Q: Can HCPL-2231-500E be used as a direct replacement for HCPL-2231#500 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. They share the same base product number (HCPL-2231), package type (8-SMD Gull Wing), and all critical electrical parameters. The only differences are packaging format and RoHS compliance status, which do not affect circuit functionality.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape spools, optimized for high-speed automated assembly lines. Cut Tape & Digi-Reel packaging provides components in smaller quantities on cut tape segments or reels, suitable for lower-volume production, prototyping, and manual assembly processes. Both formats contain identical components in the same package type.

Q: Does RoHS compliance affect the electrical performance of these parts?

A: No. RoHS compliance is a material composition and manufacturing process certification that does not alter electrical specifications, performance characteristics, or functional behavior. Both RoHS-compliant and non-compliant versions of this optoisolator deliver identical electrical performance.

Q: Are there any compatibility issues when switching between these two part numbers?

A: No compatibility issues exist. Both parts use the same 8-SMD Gull Wing package footprint, require identical PCB layout, and operate within the same electrical parameters. Schematic and PCB designs require no modification when substituting between these parts.

Q: What parameters must remain constant for a valid substitution?

A: Valid substitutions must maintain identical values for isolation voltage (3750Vrms), number of channels (2), output type (Push-Pull Totem Pole), data rate (5MBd), propagation delay (300ns max), supply voltage range (4.5V ~ 20V), operating temperature range (-40°C ~ 85°C), and package type (8-SMD Gull Wing). Variations in packaging format and compliance certifications do not invalidate substitution.
