Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FOD053LR2 are identified based on the following critical parameters that determine functional equivalence:

Matching Criteria:

• Number of Channels: 2 channels required
• Output Type: Transistor output configuration
• Current - Output / Channel: 8mA capability
• Mounting Type: Surface Mount
• Package Compatibility: 8-SOIC footprint (0.154", 3.90mm Width)
• Input Type: DC input
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Parameter Variations:

• Voltage - Isolation: Substitute parts with equal or higher isolation voltage (≥2500Vrms) are acceptable
• Voltage - Output (Max): Substitute parts with equal or higher maximum output voltage are acceptable
• Operating Temperature: Substitute parts with equal or extended temperature range are acceptable
• Current Transfer Ratio: Substitute parts with equal or higher CTR values are acceptable
• Turn On / Turn Off Time: Substitute parts with equal or faster switching times are acceptable

The three substitute parts (ACPL-054L-000E, ACPL-054L-500E, ACPL-054L-560E) meet all matching criteria and provide enhanced isolation voltage (3750Vrms) and extended output voltage capability (24V maximum).

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (ACPL-054L-000E, ACPL-054L-500E, ACPL-054L-560E) are active products with ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the FOD053LR2. The substitute parts provide enhanced electrical performance with higher isolation voltage (3750Vrms versus 2500Vrms) and extended maximum output voltage (24V versus 7V), supporting applications requiring greater isolation margins and higher output voltage capability.

The ACPL-054L-500E and ACPL-054L-560E variants offer higher inventory availability (22340 and 19640 units respectively) compared to FOD053LR2 (1682 units), with packaging options in Cut Tape (CT) & Digi-Reel® format. The ACPL-054L-000E is available in Tube packaging with 1916 units in stock. All three substitute parts support the extended operating temperature range of -40°C to 105°C, exceeding the FOD053LR2 specification of -40°C to 85°C.

Frequently Asked Questions (FAQ)

Q: Can ACPL-054L series parts directly replace FOD053LR2 in existing designs?

A: Direct PCB footprint compatibility exists due to matching 8-SOIC package dimensions (0.154", 3.90mm Width). Functional compatibility is confirmed through matching channel count (2), output type (transistor), output current capability (8mA per channel), and input type (DC). Circuit design verification is required to confirm that the enhanced isolation voltage and output voltage specifications do not create design conflicts.

Q: What are the key electrical differences between FOD053LR2 and ACPL-054L substitute parts?

A: The primary differences are isolation voltage (2500Vrms for FOD053LR2 versus 3750Vrms for ACPL-054L series), maximum output voltage (7V versus 24V), and switching speed (1µs turn-on/off time versus 200ns/380ns). Current transfer ratio specifications differ due to different test conditions (15-50% @ 16mA for FOD053LR2 versus 93-200% @ 3mA for ACPL-054L series). Operating temperature range extends from 85°C to 105°C maximum for substitute parts.

Q: Are there packaging differences between FOD053LR2 and substitute parts?

A: FOD053LR2 is supplied in Tape & Reel (TR) packaging. ACPL-054L-000E is supplied in Tube packaging, while ACPL-054L-500E and ACPL-054L-560E are supplied in Cut Tape (CT) & Digi-Reel® format. All parts use identical 8-SOIC surface mount package dimensions, ensuring PCB compatibility.

Q: Do all parts meet the same regulatory and compliance standards?

A: Yes. FOD053LR2 and all three ACPL-054L substitute parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.49.8000. All parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: Which substitute part should be selected for maximum inventory availability?

A: ACPL-054L-500E provides the highest inventory availability with 22340 units in stock, followed by ACPL-054L-560E with 19640 units. Both are supplied in Cut Tape (CT) & Digi-Reel® packaging format.
