Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCPL-053L#500 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Number of Channels: 2
• Output Type: Transistor
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Voltage - Output (Max): 7V
• Current - Output / Channel: 8mA
• Current - DC Forward (If) (Max): 25mA

Allowable Variation Parameters:

• Voltage - Isolation: Minimum 2500Vrms (lower isolation voltage acceptable for reduced-isolation applications)
• Current Transfer Ratio: Minimum 15% @ 16mA (lower CTR acceptable if circuit design accommodates)
• Turn On / Turn Off Time: Up to 1µs maximum (slower switching acceptable for non-critical timing applications)
• Operating Temperature: Minimum -40°C lower bound (reduced low-temperature range acceptable for standard industrial use)
• Voltage - Forward (Vf): 1.45V to 1.5V (minor variation acceptable)

Identified Substitutes:

1. HCPL-053L-500E (Broadcom Limited) - Parametric equivalent with identical electrical specifications and packaging. Differs only in packaging format (Cut Tape & Digi-Reel vs. Tape & Reel).

2. FOD053L (Fairchild Semiconductor) - Functional substitute with reduced isolation voltage (2500Vrms vs. 3750Vrms), lower minimum CTR (15% vs. 19%), and narrower operating temperature range (-40°C to 85°C vs. -55°C to 100°C). Acceptable for applications not requiring maximum isolation or extended temperature operation.

Parameter Comparison

Engineering Selection Recommendations

HCPL-053L-500E is the primary equivalent substitute for HCPL-053L#500. Both parts are manufactured by Broadcom Limited with identical electrical and mechanical specifications. The only difference is packaging format: HCPL-053L-500E is supplied in Cut Tape & Digi-Reel format versus Tape & Reel for the main part. HCPL-053L-500E achieves ROHS3 compliance, whereas HCPL-053L#500 is RoHS non-compliant. Selection between these two should be based on packaging requirements and regulatory compliance mandates for the end application.

FOD053L is a functional substitute suitable for applications where reduced isolation voltage and narrower operating temperature range are acceptable. This part is manufactured by Fairchild Semiconductor and is ROHS3 compliant. The FOD053L exhibits lower minimum current transfer ratio (15% vs. 19%) and slower switching response (1µs vs. 200ns/600ns). Applications requiring maximum isolation voltage (3750Vrms), extended low-temperature operation (-55°C), or faster switching response should use HCPL-053L#500 or HCPL-053L-500E rather than FOD053L.

Frequently Asked Questions (FAQ)

Q: Can HCPL-053L-500E be used as a direct replacement for HCPL-053L#500?

A: Yes. Both parts have identical electrical specifications, channel count, isolation voltage, current transfer ratio, switching times, output voltage, and operating temperature range. The parts differ only in packaging format (Cut Tape & Digi-Reel vs. Tape & Reel) and RoHS compliance status. Direct substitution is electrically valid.

Q: What are the limitations of using FOD053L instead of HCPL-053L#500?

A: FOD053L has three key limitations: (1) Isolation voltage is 2500Vrms instead of 3750Vrms, reducing isolation capability; (2) Minimum current transfer ratio is 15% instead of 19%, requiring circuit design adjustment for adequate output current; (3) Operating temperature range is -40°C to 85°C instead of -55°C to 100°C, limiting use in extended temperature environments. FOD053L is suitable only for applications that do not require maximum isolation voltage or extended temperature operation.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 8-SOIC package with 0.154" width and identical pinout for 2-channel transistor output optoisolators. PCB layout and footprint are interchangeable.

Q: Which substitute part has the best compliance status?

A: Both HCPL-053L-500E and FOD053L are ROHS3 compliant. HCPL-053L#500 is RoHS non-compliant. For applications requiring RoHS compliance, use either HCPL-053L-500E or FOD053L.

Q: Does switching speed differ between these parts?

A: Yes. HCPL-053L#500 and HCPL-053L-500E have identical switching times of 200ns turn-on and 600ns turn-off. FOD053L has slower switching with 1µs maximum for both turn-on and turn-off. Applications requiring fast switching response should use HCPL-053L#500 or HCPL-053L-500E.

Q: What inventory levels are available for each part?

A: HCPL-053L#500 has 838 units in stock. HCPL-053L-500E has 20,200 units in stock. FOD053L has 1,588 units in stock. Availability should be confirmed with the supplier for production quantities.
