Substitute Part Grouping Explanation

Substitute parts for the HCPL-2601-360E are qualified based on the following criteria:

Single-channel configuration: All substitutes maintain 1 input and 1 output channel
Data rate compatibility: All substitutes operate at 10MBd, matching the main part
Input type: All substitutes accept DC input signals
Isolation voltage: Substitutes meet or exceed the 3750Vrms isolation requirement
Common mode transient immunity: Substitutes meet or exceed 10kV/µs CMTI
Supply voltage range: Substitutes operate within compatible supply voltage windows
Manufacturer: All substitutes are manufactured by Broadcom Limited
Compliance: All substitutes maintain ROHS3 compliance and REACH unaffected status

The primary differences between the main part and substitutes are output stage topology (open collector vs. tri-state vs. push-pull), isolation voltage rating, CMTI performance, output current capability, and package form factor. These variations allow selection based on specific circuit requirements and board layout constraints.

Engineering Selection Recommendations

All three parts maintain active product status and full ROHS3 compliance, ensuring long-term availability and regulatory alignment. Selection between the main part and substitutes depends on specific circuit requirements:

HCPL-2601-360E is selected when open collector output topology with 50 mA output current is required, and the 3750Vrms isolation voltage meets system specifications. The 4.5V to 5.5V supply range is suitable for standard 5V logic systems.

ACPL-C61L-060E provides tri-state output capability with higher isolation voltage (5000Vrms) and superior CMTI performance (20kV/µs). The expanded supply voltage range (2.7V to 5.5V) accommodates lower-voltage systems. The 8-SOIC package maintains similar board footprint to the main part.

ACPL-W61L-060E offers push-pull totem pole output with the highest isolation voltage (5000Vrms) and CMTI (20kV/µs). The 6-SOIC package is more compact than the 8-pin alternatives. Extended operating temperature range (-40°C to 105°C) supports wider thermal environments.

All parts are manufactured by Broadcom Limited and carry identical compliance certifications (REACH unaffected, EAR99 ECCN classification).

Frequently Asked Questions (FAQ)

Q: Can ACPL-C61L-060E replace HCPL-2601-360E in existing designs?

A: Functional replacement is possible if the circuit design accommodates tri-state output topology instead of open collector. The higher isolation voltage and CMTI provide enhanced performance margins. The 8-SOIC package footprint differs from the 8-DIP Gull Wing, requiring PCB layout modification.

Q: What is the primary difference between ACPL-C61L-060E and ACPL-W61L-060E?

A: Output stage topology differs: ACPL-C61L-060E uses tri-state logic, while ACPL-W61L-060E uses push-pull totem pole. ACPL-W61L-060E has lower propagation delay (80ns vs. 90ns) and uses a 6-pin package instead of 8-pin. Both provide identical isolation voltage and CMTI performance.

Q: Are package changes required when substituting these parts?

A: Yes. HCPL-2601-360E uses 8-DIP Gull Wing; ACPL-C61L-060E uses 8-SOIC; ACPL-W61L-060E uses 6-SOIC. PCB layout and footprint modifications are necessary for any substitution.

Q: Do all substitutes support the same supply voltage as the main part?

A: No. HCPL-2601-360E requires 4.5V to 5.5V supply. Both substitutes accept 2.7V to 5.5V, providing broader supply voltage compatibility for low-voltage applications.

Q: What output current capability should be considered when selecting a substitute?

A: HCPL-2601-360E provides 50 mA output current. Both substitutes provide 10 mA. If the application requires 50 mA output drive, the main part is the only option among these three.

Q: Are all parts suitable for extended temperature applications?

A: HCPL-2601-360E operates -40°C to 85°C. Both substitutes extend to -40°C to 105°C, providing superior performance in high-temperature environments.
