ACPL-072L-060E Equivalent & Substitute Parts

Part Overview

The ACPL-072L-060E is a logic output optoisolator manufactured by Broadcom Limited, designed for high-speed digital isolation applications. This 1-channel device provides 3750Vrms isolation with push-pull totem pole output configuration, operating at 25MBd data rate with 10kV/µs common mode transient immunity. The part is active in production status and widely used in industrial control, power management, and communication interface circuits requiring galvanic isolation.

Substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits selection from alternative manufacturers offering equivalent electrical and mechanical performance within the same isolation and speed class.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ACPL-072L-060E is determined by the following critical parameters:

Primary Substitution Criteria:

• Voltage isolation rating: 3750Vrms (mandatory match)
• Number of channels: 1 (single-channel requirement)
• Output configuration: Push-Pull, Totem Pole (mandatory match)
• Package type: 8-SOIC form factor (mandatory match for PCB compatibility)
• Current output per channel: 10 mA (mandatory match)
• Input type: Logic (mandatory match)

Secondary Compatibility Parameters:

• Data rate: 25MBd or lower (backward compatible)
• Common mode transient immunity: 10kV/µs or higher (backward compatible)
• Propagation delay: 40ns or lower (backward compatible)
• Supply voltage range: Must support 3V ~ 3.6V and/or 4.5V ~ 5.5V
• Operating temperature range: Must cover -40°C ~ 105°C or equivalent industrial range
• Compliance: ROHS3 and MSL Level 1 preferred for consistency

Substitute parts meeting all primary criteria and at least the secondary parameters are electrically and mechanically interchangeable with the ACPL-072L-060E in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Single-Channel, 25MBd):

FOD0720, FOD0720R2, FOD0721, and FOD0721R2 are functionally equivalent to the ACPL-072L-060E for applications requiring 25Mbps data rate operation. These parts maintain identical isolation voltage, output configuration, propagation delay, and 10mA output current specifications. FOD0720R2 and FOD0721R2 carry ROHS3 compliance and MSL Level 1 ratings, matching the primary part's environmental certifications. FOD0720 and FOD0721 lack specified compliance documentation but are electrically equivalent. All four parts operate within the 4.5V ~ 5.5V supply range; applications requiring 3V ~ 3.6V operation should be evaluated against actual circuit requirements.

Lower Data Rate Alternative (Single-Channel, 12.5Mbps):

FOD0710 and FOD0710R2 operate at 12.5Mbps, half the data rate of the ACPL-072L-060E. These parts are suitable for applications where bandwidth requirements do not exceed 12.5Mbps and where cost or availability favors selection. Both maintain 3750Vrms isolation, 10mA output current, and identical propagation delay specifications. FOD0710R2 includes ROHS3 compliance and MSL Level 1 certification. Operating temperature range is -40°C ~ 100°C, one degree lower than the primary part.

Multi-Channel Alternative (2-Channel, 25MBd):

ACSL-7210-06RE is a 2-channel variant from Broadcom Limited with 25MBd operation and enhanced 25kV/µs common mode transient immunity. This part is not a direct pin-for-pin substitute due to dual-channel configuration but provides superior noise immunity for applications where two isolated channels are required. It maintains identical supply voltage range (3V ~ 3.6V, 4.5V ~ 5.5V), operating temperature (-40°C ~ 105°C), and compliance certifications as the primary part.

Selection Basis:

All recommended substitutes maintain active product status and ROHS3/REACH compliance where specified. Selection should prioritize parts with documented MSL Level 1 and ROHS3 ratings for consistency with the primary part's environmental specifications. Supply voltage compatibility must be verified against circuit design requirements, particularly for applications utilizing the 3V ~ 3.6V range, which is supported only by the ACPL-072L-060E and ACSL-7210-06RE.

Frequently Asked Questions (FAQ)

Q: Can FOD0710 or FOD0710R2 replace the ACPL-072L-060E in all applications?

A: FOD0710 and FOD0710R2 are electrically compatible for applications where data rate does not exceed 12.5Mbps. The ACPL-072L-060E operates at 25MBd; substitution with lower-speed parts is backward compatible only if circuit bandwidth requirements permit. Both parts maintain 3750Vrms isolation, 10mA output current, and identical propagation delay. Operating temperature range is -40°C ~ 100°C versus -40°C ~ 105°C for the primary part.

Q: Is ACSL-7210-06RE a direct pin-for-pin replacement?

A: No. ACSL-7210-06RE is a 2-channel optoisolator versus the 1-channel ACPL-072L-060E. Pin configuration differs due to dual-channel architecture. This part is suitable only for designs requiring two isolated channels. It shares identical isolation voltage, data rate, supply voltage range, and operating temperature specifications.

Q: What is the difference between FOD0720 and FOD0720R2?

A: FOD0720 is supplied in bulk packaging; FOD0720R2 is supplied in tape and reel (TR) format. Both are electrically identical with 25Mbps data rate, 3750Vrms isolation, and 10mA output current. FOD0720R2 includes documented ROHS3 compliance and MSL Level 1 certification. Selection depends on packaging requirements and supply chain availability.

Q: Can I use FOD0721 instead of FOD0720?

A: Yes. FOD0721 and FOD0720 are electrically equivalent, both operating at 25Mbps with 3750Vrms isolation and 10mA output current. FOD0721 is manufactured by onsemi; FOD0720 by Fairchild Semiconductor. Both maintain identical propagation delay and output configuration. Selection depends on manufacturer preference and supply availability.

Q: Does the ACPL-072L-060E support 3V operation?

A: Yes. The ACPL-072L-060E supports dual supply voltage ranges: 3V ~ 3.6V and 4.5V ~ 5.5V. Most substitute parts (FOD0710, FOD0710R2, FOD0720, FOD0720R2, FOD0721, FOD0721R2) support only 4.5V ~ 5.5V. If 3V operation is required, use ACSL-7210-06RE or remain with the ACPL-072L-060E.

Q: What is the significance of common mode transient immunity (CMTI) differences?

A: The ACPL-072L-060E specifies 10kV/µs CMTI; substitute parts specify 20kV/µs or 25kV/µs. Higher CMTI values indicate superior noise rejection during fast voltage transitions on the isolated side. Substitution with higher CMTI parts is compatible and provides improved performance. Substitution with lower CMTI parts is not recommended.

Q: Are all substitute parts ROHS3 compliant?

A: No. FOD0710, FOD0720, and FOD0720R2 do not specify ROHS3 compliance in provided documentation. FOD0710R2, FOD0721, FOD0721R2, and ACSL-7210-06RE are documented as ROHS3 compliant. For applications requiring ROHS3 certification, select from the compliant subset.

Q: What is MSL Level 1, and why does it matter?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture bake-out requirements. The ACPL-072L-060E carries MSL Level 1. Substitute parts with MSL Level 1 (FOD0710R2, FOD0721, FOD0721R2, ACSL-7210-06RE) offer equivalent storage flexibility. Parts without specified MSL may require moisture control during storage and handling.
