Key Parameters

Substitute Part Grouping Explanation

The ACPL-P454-520E belongs to the ACPL-P454 base product family. Substitute parts within this family maintain identical electrical specifications across all critical parameters: isolation voltage (3750Vrms), channel count (1), current transfer ratio range (25%-60% @ 16mA), switching times (200ns/300ns), output characteristics (20V maximum, 8mA per channel), and input specifications (1.5V forward voltage, 25mA maximum forward current). All substitute parts share the same 6-SOIC surface mount package, operating temperature range (-55°C to 100°C), and compliance certifications (ROHS3, MSL 1). Substitution is valid when the part number variant differs only in the suffix designation while maintaining the base product number ACPL-P454 and all specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both ACPL-P454-520E and ACPL-P454-500E are active production parts from Broadcom Limited with full ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability, supply chain considerations, or procurement lead times. The ACPL-P454-500E currently maintains higher inventory levels (5200 pcs) compared to ACPL-P454-520E (858 pcs). Both parts meet the same compliance requirements (ROHS3 Compliant, MSL 1, REACH Unaffected, EAR99 classification) and are suitable for direct substitution in applications requiring 3750Vrms isolation with single-channel transistor output in 6-SOIC packaging.

Frequently Asked Questions (FAQ)

Q: Can ACPL-P454-500E be used as a direct replacement for ACPL-P454-520E?

A: Yes. Both parts maintain identical electrical parameters including isolation voltage (3750Vrms), current transfer ratio (25%-60% @ 16mA), switching times (200ns/300ns), and output specifications (20V maximum, 8mA per channel). The 6-SOIC package dimensions and surface mount configuration are identical. No circuit modifications are required.

Q: What determines substitution eligibility within the ACPL-P454 family?

A: Substitution is valid when parts share the base product number ACPL-P454 and maintain all critical electrical parameters: isolation voltage, channel count, current transfer ratio range, switching times, output voltage and current ratings, input specifications, operating temperature range, and package type. Compliance certifications (ROHS3, MSL level) must also be equivalent.

Q: Are there any package or mounting differences between these parts?

A: No. Both ACPL-P454-520E and ACPL-P454-500E use identical 6-SOIC (0.268", 6.80mm Width) surface mount packages. PCB footprints and assembly processes are interchangeable.

Q: What is the significance of the part number suffix (-520E vs -500E)?

A: The suffix designates specific product variants within the ACPL-P454 family. When all electrical and mechanical parameters are identical, suffix variations do not affect functional compatibility or circuit performance.

Q: Are both parts compliant with current environmental and trade regulations?

A: Yes. Both ACPL-P454-520E and ACPL-P454-500E are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes. Moisture sensitivity level is 1 (Unlimited) for both parts.
