Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 5746861-4

The TE Connectivity 5746861-4 is the direct equivalent substitute for the obsolete 746861-4. This part maintains identical electrical and mechanical specifications while offering active product status and improved regulatory compliance. The 5746861-4 is RoHS Compliant with REACH Affected status, providing superior environmental compliance compared to the original non-compliant part.

Secondary Recommendations: Amphenol ICC DFR Series

The Amphenol ICC L117 and L17 series connectors provide functional equivalence with enhanced electrical performance characteristics. These parts are suitable for applications where the original 1.25A current rating is insufficient or where extended operating temperature ranges are required.

Selection by Application Requirements:

Standard Current Applications (≤1.25A): TE Connectivity 5746861-4 or Amphenol ICC L117DEFRA09S, L117DEFRB09S, L17DEFRA09SC309
Higher Current Applications (3A-5A): Amphenol ICC L117DEFRAA09S, L117DEFRBA09S, L117DEFRCA09S, L17DEFRAA09S, L17DEFRAA09SC309
Extended Temperature Range (-40°C to 125°C): Amphenol ICC L117DEFRAA09S, L117DEFRBA09S, L117DEFRCA09S
Flange Feature Specific Requirements: Refer to Parameter Comparison table for flange configuration options (Housing/Shell, Mating Side Screwlock, Cable Side)

All substitute parts maintain UL94 V-0 flammability rating, gold contact finish, and IDC ribbon cable termination compatibility.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5746861-4 be used as a direct replacement for the 746861-4?

A: Yes. The 5746861-4 maintains identical connector style, position count, shell size, mounting type, termination method, contact finish, and operating temperature range. The primary differences are active product status and improved RoHS compliance.

Q: What is the difference between the TE Connectivity and Amphenol ICC substitute options?

A: The TE Connectivity 5746861-4 is a direct equivalent from the same manufacturer. Amphenol ICC DFR series connectors are functional equivalents that meet all primary compatibility criteria but offer variations in current rating (3A-5A versus 1.25A), operating temperature range, flange features, and contact finish thickness.

Q: Are the Amphenol ICC L117 and L17 series connectors mechanically compatible with the original 746861-4?

A: Yes. All substitute parts share identical D-Sub connector style, 9-position configuration, 2-row layout, shell size 1 (DE, E), free-hanging in-line mounting, and IDC ribbon cable termination. Mechanical compatibility is maintained across all listed substitutes.

Q: What does the flange feature designation mean, and does it affect substitution?

A: Flange features define the mounting interface. Options include Housing/Shell (unthreaded or threaded 4-40), Mating Side Female Screwlock (M3 or 4-40), and Cable Side (M3 or 4-40). Selection depends on the specific application's mounting requirements. The original 746861-4 features Housing/Shell (4-40).

Q: Why do some substitute parts have higher current ratings than the original?

A: Amphenol ICC DFR series connectors are engineered with enhanced contact materials and configurations that support 3A to 5A current ratings compared to the original 1.25A. These parts are suitable for applications requiring higher current capacity while maintaining all other compatibility parameters.

Q: What is the significance of contact finish thickness differences?

A: The original 746861-4 specifies 30.0µin (0.76µm) gold plating. Most Amphenol ICC substitutes provide 15.0µin (0.38µm) thickness, which remains within acceptable gold plating standards for signal-level applications. The L17 series with SC309 designation and L17DEFRAA09S maintain thicker or flash plating options.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are RoHS Compliant or ROHS3 Compliant. The original 746861-4 is RoHS non-compliant, making substitution necessary for applications requiring environmental compliance.

Q: What packaging options are available for the substitute parts?

A: TE Connectivity 5746861-4 is supplied in tube packaging. Amphenol ICC DFR series connectors are supplied in tray packaging. Packaging selection may affect procurement and handling procedures.

Q: Can I use a substitute part with a higher operating temperature range in place of the original?

A: Yes. Amphenol ICC parts rated for -40°C to 125°C operating temperature can be used in applications originally specified for -55°C to 105°C. The extended range provides additional thermal margin without compromising compatibility.

Q: Which substitute part most closely matches the original 746861-4 specifications?

A: The TE Connectivity 5746861-4 provides the closest match with identical electrical and mechanical specifications. For applications requiring Amphenol ICC components, the L17DEFRA09SC309 maintains the same 30.0µin contact finish thickness and 1.25A-compatible current rating as the original part.
