SLA5022 Equivalent & Substitute Parts

Part Overview

The SLA5022 is a general-purpose transistor array manufactured by Sanken Electric USA Inc., configured as a 3 PNP Darlington and 3 N-Channel (3-Phase Bridge) device rated for 60V and 6A operation. The component is packaged in a 12-SIP Exposed Tab through-hole configuration and is currently classified as obsolete. Due to its obsolete status, identifying functionally equivalent substitute parts is essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

The SLA5060 qualifies as a substitute for the SLA5022 based on the following critical parameters:

• Voltage Rating: Both devices are rated for 60V maximum drain-to-source voltage (Vdss)
• Current Rating: Both devices support 6A continuous current operation
• Configuration: Both devices provide 3-phase bridge functionality with complementary channel pairs
• Package: Both devices use 12-SIP Exposed Tab through-hole packaging
• Mounting Type: Both are through-hole mounted components
• Manufacturer: Both are manufactured by Sanken Electric USA Inc.
• Base Product Number: Both share the SLA50 base product designation
• Compliance: Both are RoHS Compliant with MSL 1 rating

The primary functional difference is the technology transition from bipolar transistor arrays (SLA5022) to MOSFET arrays (SLA5060), which maintains electrical compatibility within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

The SLA5060 is the designated substitute for the obsolete SLA5022. Selection is based on:

• Product Status: The SLA5022 is obsolete; the SLA5060 is active and currently in production
• Electrical Compatibility: Both devices meet the 60V, 6A, and 3-phase bridge configuration requirements
• Compliance Alignment: Both devices maintain RoHS compliance and identical MSL ratings
• Package Continuity: Identical 12-SIP Exposed Tab through-hole packaging ensures mechanical compatibility with existing PCB layouts
• Manufacturer Continuity: Both components are manufactured by Sanken Electric USA Inc., ensuring design lineage and support

The transition from bipolar to MOSFET technology in the SLA5060 provides improved efficiency characteristics while maintaining the specified electrical operating envelope.

Frequently Asked Questions (FAQ)

Q: Can the SLA5060 directly replace the SLA5022 in existing designs?

A: Yes. Both devices share identical voltage ratings (60V), current ratings (6A), 3-phase bridge configuration, and 12-SIP Exposed Tab packaging. No PCB modifications are required for mechanical or electrical compatibility within the specified parameter range.

Q: What is the primary difference between the SLA5022 and SLA5060?

A: The SLA5022 uses bipolar transistor technology (PNP Darlington and N-Channel), while the SLA5060 uses MOSFET technology. Both maintain the same voltage, current, and package specifications.

Q: Why is the SLA5022 listed as obsolete?

A: The SLA5022 has been discontinued by the manufacturer. The SLA5060 represents the active product line continuation for this device family.

Q: Are there any compliance differences between the two parts?

A: No. Both the SLA5022 and SLA5060 are RoHS Compliant with MSL 1 (Unlimited) ratings and share identical ECCN and HTSUS classifications.

Q: What inventory status should be considered for procurement?

A: The SLA5022 has 1410 pieces available as new original stock. The SLA5060 has 2550 pieces available as new original stock and is the recommended choice for new designs due to its active product status.
