HCPL-253L-000E Equivalent & Substitute Parts

Part Overview

The HCPL-253L-000E is a 2-channel optoisolator with transistor output manufactured by Broadcom Limited. This component provides 3750Vrms isolation voltage and is designed for applications requiring galvanic isolation between input and output circuits. The part is currently in active production status. Substitute parts may be required due to supply constraints, design optimization, or application-specific performance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HCPL-253L-000E is evaluated based on the following critical parameters:

• Package compatibility: 8-DIP (0.300", 7.62mm) form factor for direct board-level replacement
• Channel configuration: 2-channel transistor output architecture
• Isolation voltage: Minimum 2500Vrms required for functional equivalence
• Input/Output characteristics: DC input with transistor output topology
• Operating temperature range: -55°C to 100°C compatibility
• Mounting type: Through-hole technology

The TLP2530(F) from Toshiba Semiconductor and Storage meets these substitution criteria within the allowed parameter tolerance for this product category.

Engineering Selection Recommendations

The HCPL-253L-000E is the primary component choice, as it maintains active production status and ROHS3 compliance. The TLP2530(F) is classified as obsolete and carries RoHS compliance (non-ROHS3). Selection between these parts should be based on:

• Active production requirement: HCPL-253L-000E is recommended for new designs and long-term supply assurance
• Isolation voltage specification: Applications requiring 3750Vrms isolation must use HCPL-253L-000E; applications tolerating 2500Vrms isolation may use TLP2530(F)
• Current transfer ratio: HCPL-253L-000E provides higher minimum CTR (19% vs 7%), affecting circuit gain and design margins
• Compliance requirements: ROHS3 compliance is achieved with HCPL-253L-000E; legacy systems may accept RoHS-compliant TLP2530(F)

Frequently Asked Questions (FAQ)

Q: Can TLP2530(F) directly replace HCPL-253L-000E in existing designs?

A: Direct replacement is possible only if the application tolerates reduced isolation voltage (2500Vrms vs 3750Vrms) and lower current transfer ratio (7% minimum vs 19% minimum). Package and pinout are identical (8-DIP). Circuit validation is required for each application.

Q: What are the key differences between these parts?

A: The primary differences are isolation voltage rating (3750Vrms vs 2500Vrms), current transfer ratio performance (19-50% vs 7%), and product status (active vs obsolete). Both parts share identical package geometry, channel count, operating temperature range, and forward current specifications.

Q: Is the 8-DIP package identical between both parts?

A: Yes. Both HCPL-253L-000E and TLP2530(F) use 8-DIP (0.300", 7.62mm) through-hole packaging, enabling direct board-level substitution from a mechanical standpoint.

Q: Which part should be selected for new product designs?

A: HCPL-253L-000E is the appropriate choice for new designs due to active production status, higher isolation voltage rating, superior current transfer ratio, and ROHS3 compliance.

Q: Are there compliance differences between these parts?

A: HCPL-253L-000E is ROHS3 compliant, while TLP2530(F) is RoHS compliant. Both parts carry EAR99 ECCN classification and are REACH unaffected.
