Key Parameters

Substitute Part Grouping Explanation

Substitution between HCPL-061A#500 and HCPL-061A-500E is based on strict equivalence of the following critical parameters:

• Isolation voltage: 3750Vrms (identical)
• Number of channels: 1 (identical)
• Output configuration: Open Collector, Schottky Clamped (identical)
• Output current capability: 50 mA per channel (identical)
• Data rate: 10MBd (identical)
• Common Mode Transient Immunity: 1kV/µs minimum (identical)
• Supply voltage range: 4.5V ~ 5.5V (identical)
• Operating temperature range: -40°C ~ 85°C (identical)
• Package type: 8-SOIC (0.154", 3.90mm Width) (identical)
• Mounting type: Surface Mount (identical)

The primary difference between these parts is packaging format: HCPL-061A#500 is supplied in Tape & Reel (TR) format, while HCPL-061A-500E is supplied in Cut Tape (CT) & Digi-Reel® format. Both parts share the same base product number (HCPL-061) and are manufactured by Broadcom Limited.

Parameter Comparison

Engineering Selection Recommendations

Both HCPL-061A#500 and HCPL-061A-500E are electrically and mechanically equivalent optoisolators suitable for direct substitution in circuit designs. Selection between these parts should be based on the following criteria:

HCPL-061A#500 (Tape & Reel): Select this part for high-volume production runs where automated tape-fed assembly equipment is utilized. This packaging format is optimized for pick-and-place machine compatibility.

HCPL-061A-500E (Cut Tape & Digi-Reel®): Select this part when RoHS3 compliance is required for end-product certification. This variant also provides flexibility for lower-volume applications or manual assembly processes where cut tape format is preferred.

Both parts maintain identical electrical performance, isolation ratings, timing characteristics, and thermal operating ranges. The choice between them is determined by production methodology, regulatory compliance requirements, and supply chain availability rather than functional capability.

Frequently Asked Questions (FAQ)

Q: Can HCPL-061A-500E be used as a direct replacement for HCPL-061A#500 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. They share the same 8-SOIC package footprint, supply voltage requirements, isolation voltage rating, output current capability, and timing specifications. The only differences are packaging format and RoHS compliance status.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) format supplies components on continuous carrier tape wound on a reel, optimized for automated assembly lines with tape-fed pick-and-place equipment. Cut Tape (CT) & Digi-Reel® format provides the same components on cut tape segments, suitable for lower-volume production, manual assembly, or applications requiring smaller quantities per order.

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS3 compliance status reflects manufacturing process and material composition standards, not electrical or functional performance. Both parts deliver identical isolation voltage, output current, data rate, and timing characteristics. The RoHS3 compliant variant (HCPL-061A-500E) is required only when end-product certification mandates RoHS compliance.

Q: Are the propagation delay and rise/fall time specifications identical between these parts?

A: Yes. Both HCPL-061A#500 and HCPL-061A-500E specify maximum propagation delays of 100ns for both tpLH and tpHL, with typical rise time of 42ns and fall time of 12ns. These timing parameters are identical across both variants.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. Both parts use the same 8-SOIC (0.154", 3.90mm Width) surface mount package. PCB footprints, solder pad layouts, and component placement are identical. No design modifications are required when substituting between these parts.
