Automotive Connector Terminal – SAITWS-A03GF-064 / DJ615E-0.6A, 0.6mm Female Crimp Contact

SAITWS-A03GF-064 / DJ615E-0.6A are 0.6mm pitch female crimp terminals for high-density automotive connector systems. The SAITWS prefix indicates a Sumitomo Electric Industries (SEI) terminal designation — Sumitomo is a major Japanese automotive connector manufacturer supplying Toyota, Honda, Nissan, and other Japanese OEM vehicle platforms. The 0.6mm contact size is used in high-density connector systems where circuit count requirements exceed what can be achieved with 1.2mm or 1.5mm pitch contacts.

Frequently Asked Questions

What crimp tool is required for SAITWS-A03GF-064 terminals?

Sumitomo specifies a dedicated micro-crimp tool for 0.6mm contacts. The correct tool produces a crimp meeting Sumitomo’s pull-out force specification. Using a standard automotive crimp tool will crush 0.6mm terminals. For professional ECU harness repair on Japanese vehicles, use a Sumitomo-specified micro-crimp tool or a universal micro-crimp tool with the correct die for 0.6mm contacts.

How do I identify Sumitomo terminals in my Toyota/Honda vehicle?

Sumitomo connectors are typically marked with the Sumitomo logo or part number on the housing. Cross-reference the terminal part number (SAITWS-A03GF-064) with the vehicle’s wiring diagram parts list or the Sumitomo catalog to verify compatibility. For Toyota and Honda vehicles, the OEM parts catalog lists connector and terminal part numbers by vehicle system and connector location.

Can I repair ECU connectors with these terminals?

Yes. Individual terminal replacement is the most cost-effective repair for ECU connectors with 1–3 damaged terminals. Follow the vehicle manufacturer’s ECU connector repair procedure: disable the ignition, use a micro extraction tool to remove the damaged terminal, crimp a new terminal onto the wire, reinsert, and verify with a scan tool after reassembly.

Typical Applications

• Toyota/Honda vehicles: ECU, TCM, and body electronics terminal replacement
• Japanese OEM repair: Sumitomo terminal replacement in high-density connector systems
• Automotive workshops: Workshop stock for Japanese vehicle terminal repairs
• Harness manufacturing: Loose terminals for custom harness builds using Sumitomo housings
