ACPL-217-500E Equivalent & Substitute Parts

Part Overview

The ACPL-217-500E is a high-voltage optoisolator manufactured by Broadcom Limited, designed for galvanic isolation applications requiring 3750Vrms isolation voltage. This single-channel transistor output optoisolator operates with DC input and delivers up to 50mA output current in a 4-SOIC surface mount package. The device is Active status and ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified based on matching critical electrical and mechanical parameters that ensure functional interchangeability within the same application circuit topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ACPL-217-500E is determined by strict equivalence across the following critical parameters:

• Isolation voltage: 3750Vrms
• Single channel configuration
• Transistor output topology
• DC input type
• Current transfer ratio range: 50% to 600% @ 5mA
• Maximum output voltage: 80V
• Maximum output current: 50mA per channel
• Surface mount technology
• Operating temperature range: -55°C to 110°C minimum
• RoHS3 compliance
• MSL 1 rating

All identified substitute parts meet these core electrical and mechanical requirements. Package variants (4-SOIC, 4-SSOP, 4-Mini-Flat) are considered compatible within the same footprint class for surface mount applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment with the original ACPL-217-500E.

ACPL-217-560E (Broadcom Limited) provides identical electrical specifications and is the direct parametric equivalent within the same manufacturer family, differing only in internal design revision.

HMHA2801 (onsemi) offers improved Vce saturation performance (300mV vs 400mV) but operates to 100°C maximum versus 110°C for the primary part. This substitution is suitable for applications not requiring the extended upper temperature range.

EL3H7(EA)-VG and EL3H7(TA)-VG (Everlight Electronics) deliver superior Vce saturation (200mV) and maintain the full -55°C to 110°C operating range. These parts differ in packaging format (Tape & Reel vs Cut Tape) but are electrically identical.

LTV-217-G (Lite-On Inc.) and VOS617A-X001T / VOS617AT (Vishay) maintain full parameter equivalence with the ACPL-217-500E across all critical specifications and temperature range.

Frequently Asked Questions (FAQ)

Q: Can ACPL-217-500E be replaced with ACPL-217-560E?

A: Yes. Both parts are manufactured by Broadcom Limited and share identical electrical parameters, isolation voltage, current transfer ratio range, output current rating, and operating temperature range. The substitution is direct.

Q: What is the difference between EL3H7(EA)-VG and EL3H7(TA)-VG?

A: Both parts are electrically identical with matching isolation voltage, current transfer ratio, and operating temperature specifications. The difference is packaging format: EL3H7(EA)-VG is supplied in Tape & Reel format, while EL3H7(TA)-VG is supplied in Cut Tape & Digi-Reel format. Selection depends on procurement and assembly requirements.

Q: Is HMHA2801 a suitable replacement for ACPL-217-500E?

A: HMHA2801 meets all core electrical requirements including 3750Vrms isolation, 50-600% current transfer ratio, and 50mA output current. However, the maximum operating temperature is 100°C compared to 110°C for ACPL-217-500E. This substitution is appropriate for applications operating within -55°C to 100°C range.

Q: Do all substitute parts use the same package footprint?

A: No. ACPL-217-500E and ACPL-217-560E use 4-SOIC packaging. HMHA2801 uses 4-Mini-Flat packaging. EL3H7(EA)-VG, EL3H7(TA)-VG, LTV-217-G, VOS617A-X001T, and VOS617AT use 4-SSOP packaging. While all are surface mount with 4.40mm width, PCB layout and footprint files must be verified for each package type.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental and regulatory status of the ACPL-217-500E.

Q: What is the significance of Vce saturation differences among substitutes?

A: Vce saturation affects output voltage drop and power dissipation in the transistor output stage. ACPL-217-500E, HMHA2801, and Vishay parts specify 400mV or 300mV maximum saturation voltage. Everlight EL3H7 variants specify 200mV, resulting in lower output voltage drop and reduced power consumption. All values remain within acceptable limits for standard optoisolator applications.

Q: Can I use VOS617A-X001T and VOS617AT interchangeably?

A: Yes. Both Vishay parts share identical electrical specifications, isolation voltage, current transfer ratio, output current, and operating temperature range. Selection between them depends on packaging format and procurement availability.
