Substitute Part Grouping Explanation

Substitute parts for the HCPL-M456-060E are qualified based on the following criteria:

Mandatory Compatibility Parameters:

• Voltage - Isolation: 3750Vrms (exact match required)
• Number of Channels: 1 (exact match required)
• Input Type: DC (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Package / Case: 6-SOIC (0.173", 4.40mm Width), 5 Leads (exact match required)
• Voltage - Supply: 4.5V ~ 30V (exact match required)

Functional Differences in Substitutes: The substitute parts ACPL-M483-060E and ACPL-M484-060E feature Push-Pull, Totem Pole output configuration instead of Open Collector, Schottky Clamped. These substitutes provide higher output current capability (50 mA vs. 15 mA), faster propagation delay (120ns vs. 550ns/400ns), and enhanced common mode transient immunity (30kV/µs vs. 15kV/µs). Both substitute parts maintain Active product status and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Both ACPL-M483-060E and ACPL-M484-060E are qualified substitutes for the obsolete HCPL-M456-060E. Selection between these two Active alternatives depends on propagation delay requirements:

ACPL-M483-060E provides symmetric propagation delay specifications (120ns for both tpLH and tpHL) with 6ns rise and fall times.

ACPL-M484-060E provides 120ns tpLH and 150ns tpHL with 6ns rise and fall times.

Both substitutes maintain ROHS3 compliance, REACH Unaffected status, and EAR99 ECCN classification. The extended operating temperature range (-40°C to 105°C vs. -40°C to 100°C) in both substitutes provides additional thermal margin. The Push-Pull, Totem Pole output configuration in both substitutes delivers higher output current (50 mA vs. 15 mA) and superior common mode transient immunity (30kV/µs vs. 15kV/µs).

Frequently Asked Questions (FAQ)

Q: Can ACPL-M483-060E and ACPL-M484-060E be used as direct replacements for HCPL-M456-060E?

A: Both parts share identical isolation voltage (3750Vrms), channel count (1), input type (DC), supply voltage range (4.5V ~ 30V), and package configuration (6-SOIC, 5 Leads). The primary functional difference is the output stage: HCPL-M456-060E uses Open Collector, Schottky Clamped output, while both substitutes use Push-Pull, Totem Pole output. This difference requires circuit-level evaluation to confirm compatibility with existing load conditions and pull-up resistor configurations.

Q: What are the key differences between ACPL-M483-060E and ACPL-M484-060E?

A: Both parts are functionally equivalent with identical isolation voltage, channel count, output current (50 mA), and common mode transient immunity (30kV/µs). The difference lies in propagation delay specifications: ACPL-M483-060E specifies 120ns for both tpLH and tpHL, while ACPL-M484-060E specifies 120ns tpLH and 150ns tpHL. Selection depends on timing-critical applications requiring symmetric delay characteristics.

Q: Are the substitute parts available in the same package?

A: Yes. All three parts use the 6-SOIC (0.173", 4.40mm Width), 5 Leads package configuration. PCB footprint compatibility is maintained across HCPL-M456-060E, ACPL-M483-060E, and ACPL-M484-060E.

Q: What is the impact of the output stage change from Open Collector to Push-Pull?

A: The output stage change affects load driving capability and circuit design requirements. Open Collector output (HCPL-M456-060E) requires external pull-up resistors and supports open-drain logic configurations. Push-Pull output (ACPL-M483-060E and ACPL-M484-060E) provides active high and low drive with 50 mA output current capability, eliminating the need for external pull-up resistors and enabling direct logic interface. Circuit topology must be evaluated to confirm compatibility.

Q: Do all three parts maintain the same compliance certifications?

A: Yes. HCPL-M456-060E, ACPL-M483-060E, and ACPL-M484-060E are all ROHS3 Compliant, REACH Unaffected, and classified as EAR99 under ECCN. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all three parts.
