Engineering Selection Recommendations

RoHS3 Compliant Substitutes (Recommended for New Designs):

For applications requiring RoHS3 compliance, the following Broadcom Limited optoisolators are direct substitutes:

• HCPL-063A-000E: Maintains 3750Vrms isolation, 2-channel configuration, and 8-SOIC package with RoHS3 compliance. Suitable for applications where 1kV/µs CMTI is acceptable.
• HCPL-063A-500E: Identical electrical specifications to HCPL-063A-000E with Cut Tape & Digi-Reel® packaging option.
• HCPL-063L-000E: Provides enhanced 10kV/µs CMTI and 15MBd data rate with RoHS3 compliance. Supports dual supply voltage range (2.7V ~ 3.6V and 4.5V ~ 5.5V).
• HCPL-063L-060E: Identical to HCPL-063L-000E with Tube packaging.
• HCPL-063N-000E: Delivers 15kV/µs CMTI with RoHS3 compliance. Highest inventory availability (119,100 pcs).
• HCPL-063N-500E: Identical to HCPL-063N-000E with Cut Tape & Digi-Reel® packaging.

Non-RoHS3 Compliant Substitutes (Legacy Applications):

For existing designs or applications without RoHS3 requirements:

• HCPL-063A: 1kV/µs CMTI variant in Tube packaging.
• HCPL-063L: 10kV/µs CMTI and 15MBd data rate in Tube packaging with dual supply voltage support.
• HCPL-063N: 15kV/µs CMTI in Tube packaging.

Performance Trade-offs:

The HCPL0639R2 specifies 25kV/µs CMTI, which exceeds all listed substitute parts. Applications requiring this specific CMTI level must retain the original part. Substitute parts with lower CMTI ratings (1kV/µs to 15kV/µs) are suitable for applications with less stringent transient immunity requirements. The HCPL-063L series offers the closest propagation delay match (75ns) to the HCPL0639R2, while HCPL-063A and HCPL-063N variants specify 100ns maximum delay.

Frequently Asked Questions (FAQ)

Q: Can HCPL-063A series parts directly replace HCPL0639R2?

A: HCPL-063A variants maintain the same 3750Vrms isolation, 2-channel configuration, and 8-SOIC package. However, they specify 1kV/µs CMTI compared to the HCPL0639R2's 25kV/µs specification. Substitution is valid only if the application does not require the higher transient immunity rating.

Q: What is the difference between HCPL-063L and HCPL-063N variants?

A: Both maintain 3750Vrms isolation and 2-channel configuration. HCPL-063L specifies 10kV/µs CMTI and 15MBd data rate with propagation delay of 75ns. HCPL-063N specifies 15kV/µs CMTI and 10MBd data rate with propagation delay of 100ns. HCPL-063L is preferred for higher-speed applications; HCPL-063N is preferred for higher transient immunity requirements.

Q: Are RoHS3 compliant and non-compliant variants electrically equivalent?

A: Yes. RoHS3 compliance is a material composition specification and does not affect electrical performance. HCPL-063A-000E and HCPL-063A are electrically identical; HCPL-063L-000E and HCPL-063L are electrically identical; HCPL-063N-000E and HCPL-063N are electrically identical.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in Tube, Cut Tape (CT) & Digi-Reel®, and Tape & Reel (TR) packaging. The original HCPL0639R2 is supplied in Tape & Reel. Broadcom Limited variants are primarily supplied in Tube or Cut Tape & Digi-Reel® formats. Packaging selection does not affect electrical performance.

Q: Can HCPL-063L variants operate at 3.3V supply voltage?

A: Yes. HCPL-063L series specifies dual supply voltage range: 2.7V ~ 3.6V and 4.5V ~ 5.5V. Other variants (HCPL-063A and HCPL-063N) specify 4.5V ~ 5.5V only. This makes HCPL-063L suitable for mixed-voltage system designs.

Q: What is the inventory status of substitute parts?

A: HCPL-063N-000E has the highest inventory (119,100 pcs). HCPL-063N-500E (15,900 pcs), HCPL-063A-500E (8,947 pcs), and HCPL-063L-060E (4,473 pcs) have substantial availability. Tube-packaged variants have lower inventory levels (1,306 to 3,750 pcs).
