Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment with the original HCPL-4701-360E.

HCPL-4701-300E is the direct parametric equivalent, offering identical electrical specifications and operating characteristics. Selection of this part requires no design modification.

6N138SMT/R and 6N139SMT&R (Isocom Components) provide enhanced isolation voltage (5000Vrms) with compatible output voltage and current ratings. Note that 6N138SMT/R specifies maximum output voltage of 7V, which is below the 18V maximum of the original part. This limitation must be evaluated against application requirements.

6N139-X009, 6N139-X009T, and 6N139-X017T (Vishay Semiconductor Opto Division) offer the highest isolation voltage (5300Vrms) with extended operating temperature range (-55°C ~ 100°C). These parts maintain 18V maximum output voltage and are available in multiple packaging formats (Tube, Tape & Reel, Cut Tape & Digi-Reel).

All substitute parts are Active status with ROHS3 compliance and REACH Unaffected designation, supporting equivalent regulatory and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can HCPL-4701-300E be used as a direct replacement for HCPL-4701-360E?

A: Yes. HCPL-4701-300E is a parametric equivalent with identical isolation voltage (3750Vrms), current transfer ratio range (600% to 8000% @ 500µA), output voltage (18V max), output current (60mA), and operating temperature range (0°C ~ 70°C). No design changes are required.

Q: What is the key difference between the Broadcom HCPL-4701 series and the Vishay 6N139 series?

A: The primary difference is isolation voltage. HCPL-4701-360E and HCPL-4701-300E provide 3750Vrms isolation, while 6N139 variants provide 5300Vrms isolation. Both maintain identical output voltage (18V max) and current (60mA) ratings. The 6N139 series also offers extended operating temperature range (-55°C ~ 100°C) compared to the standard 0°C ~ 70°C range.

Q: Why does 6N138SMT/R show a maximum output voltage of 7V instead of 18V?

A: 6N138SMT/R is specified with 7V maximum output voltage, which differs from the original part's 18V specification. This parameter must be evaluated against the application's output voltage requirements before selection.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in Tube, Tape & Reel (TR), and Cut Tape (CT) & Digi-Reel® formats. HCPL-4701-300E is supplied in Tube packaging. Vishay 6N139 variants offer multiple packaging options: 6N139-X009 (Tube), 6N139-X009T (Tape & Reel), and 6N139-X017T (Cut Tape & Digi-Reel). Isocom 6N138SMT/R and 6N139SMT&R are supplied in Tape & Reel format.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), matching the regulatory and environmental compliance of the original HCPL-4701-360E.

Q: What is the difference between 6N139-X009T and 6N139-X017T?

A: Both parts are identical in electrical specifications (5300Vrms isolation, 500% min CTR @ 1.6mA, 18V max output, 60mA output current, -55°C ~ 100°C operating range). The difference is packaging format: 6N139-X009T is supplied in Tape & Reel (TR), while 6N139-X017T is supplied in Cut Tape (CT) & Digi-Reel® format.

Q: Can I use a substitute part with higher isolation voltage in my application?

A: Yes. Higher isolation voltage (5000Vrms or 5300Vrms) is compatible with applications designed for 3750Vrms isolation. The substitute part will provide enhanced isolation margin. All other electrical parameters (output voltage, current, input type, output type) must match application requirements.
