SFH6719 Equivalent & Substitute Parts

Part Overview

The SFH6719 is a logic output optoisolator manufactured by Vishay Semiconductor Opto Division, designed for high-voltage isolation applications requiring 5300Vrms isolation rating and tri-state output configuration. This component operates at 5MBd data rate with 2.5kV/µs common mode transient immunity in an 8-DIP through-hole package.

The SFH6719 is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for optoisolators is determined by the following critical parameters:

• Isolation Voltage Rating: Minimum 5000Vrms required to maintain equivalent isolation performance
• Output Configuration: Tri-state output mandatory for functional compatibility
• Data Rate: Minimum 2.5MBd required for signal integrity
• Package Type: 8-DIP through-hole form factor required for mechanical compatibility
• Operating Temperature Range: -40°C ~ 85°C minimum required
• Output Current: 25 mA minimum per channel
• Common Mode Transient Immunity: Minimum 1kV/µs acceptable for most applications

The substitute parts listed below meet these criteria within acceptable parameter tolerances for direct replacement in equivalent circuit designs.

Parameter Comparison

Engineering Selection Recommendations

EL2200 (Everlight Electronics Co Ltd): This part maintains the highest isolation voltage rating at 5000Vrms, matching the original SFH6719 performance tier. Data rate equivalence at 5MBd ensures signal integrity. The lower common mode transient immunity specification (1kV/µs versus 2.5kV/µs) may require circuit evaluation for high-speed switching applications. Active product status ensures long-term availability and supply chain stability. ROHS3 compliance and MSL-1 rating confirm regulatory alignment.

HCPL-2219-000E and HCPL-2219-060E (Broadcom Limited): Both variants provide identical electrical specifications with 3750Vrms isolation voltage, representing a reduction from the original 5300Vrms rating. Data rate is reduced to 2.5MBd. Common mode transient immunity matches the original specification at 2.5kV/µs. These parts are suitable for applications where the lower isolation voltage is acceptable. Active product status and full compliance certifications support production deployment. The HCPL-2219 base product number indicates these are variant packaging options of the same core design.

All substitute parts maintain tri-state output configuration, 8-DIP package compatibility, 25 mA output current capability, and identical propagation delay specifications. Selection should be based on isolation voltage requirements and data rate constraints specific to the target application.

Frequently Asked Questions (FAQ)

Q: Can EL2200 directly replace SFH6719 in existing designs? A: EL2200 is mechanically and functionally compatible with SFH6719. Both parts feature 8-DIP through-hole packaging, tri-state output, 5MBd data rate, and 25 mA output current. The isolation voltage difference (5000Vrms versus 5300Vrms) is within acceptable tolerance for most applications. Circuit validation is recommended for designs operating at maximum isolation voltage specifications.

Q: What is the key difference between EL2200 and HCPL-2219 variants? A: The primary differences are isolation voltage rating and data rate. EL2200 provides 5000Vrms isolation at 5MBd, while HCPL-2219-000E and HCPL-2219-060E provide 3750Vrms isolation at 2.5MBd. Both meet the 8-DIP package requirement and tri-state output configuration. Selection depends on application isolation voltage and bandwidth requirements.

Q: Are HCPL-2219-000E and HCPL-2219-060E interchangeable? A: Yes. Both parts share identical electrical specifications and 8-DIP packaging. The designation suffix (-000E versus -060E) indicates packaging or distribution variants from Broadcom Limited. Electrical performance and pin configuration are equivalent.

Q: Do all substitute parts meet RoHS and MSL requirements? A: All listed substitute parts are ROHS3 compliant and carry MSL-1 (Unlimited) moisture sensitivity rating, matching the original SFH6719 specifications. Regulatory and environmental compliance is maintained across all alternatives.

Q: Which substitute part is recommended for new designs? A: Selection is based on isolation voltage and data rate requirements. For applications requiring 5MBd operation and high isolation voltage, EL2200 is the preferred choice. For applications where 2.5MBd data rate is acceptable and lower isolation voltage is sufficient, HCPL-2219 variants provide active product status with established supply chain support.
