Engineering Selection Recommendations

HARTING 09565527613: This substitute part is actively manufactured and maintains full mechanical and electrical compatibility with the 5748483-6. The connector meets all critical dimensional and functional requirements with identical current rating (2A) and matching flammability certification (UL94 V-0). The operating temperature range of -40°C to 85°C is narrower than the original part; applications requiring operation below -40°C or above 85°C require evaluation against specific system requirements. The part carries ROHS3 compliance and REACH unaffected status, supporting modern regulatory requirements. This option is suitable for applications where the reduced temperature range does not conflict with system specifications.

Amphenol ICC L77HDD78SD1CH4F: This substitute part is actively manufactured and provides enhanced electrical performance with a 3A current rating and 250V voltage rating, both exceeding the original 5748483-6 specifications. The connector maintains full mechanical compatibility and identical operating temperature range (-55°C to 105°C) as the original part. The addition of grounding tabs provides enhanced EMI/RFI performance. The part carries RoHS compliance status. This option is suitable for applications requiring higher current capacity, higher voltage rating, or improved grounding characteristics, and is fully compatible with the original design envelope.

Both substitute parts are actively produced, reducing supply chain risk compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the HARTING 09565527613 be used in applications requiring operation below -40°C?

A: No. The HARTING 09565527613 operating temperature range is -40°C to 85°C. Applications requiring operation at -55°C must use the Amphenol ICC L77HDD78SD1CH4F, which maintains the original -55°C to 105°C range.

Q: What is the difference in shell material finish between the substitutes?

A: The TE Connectivity 5748483-6 and HARTING 09565527613 feature nickel-plated steel shells. The Amphenol ICC L77HDD78SD1CH4F features a tin-plated steel shell. Both finishes provide corrosion protection and are suitable for standard environmental conditions.

Q: Does the Amphenol ICC L77HDD78SD1CH4F grounding tab feature affect mechanical fit?

A: No. The grounding tabs are integrated into the connector design and do not affect the mating interface or mounting footprint. The connector maintains the same shell size (5 DD/D High Density) and mounting configuration as the original part.

Q: Are all three connectors compatible with the same mating plugs?

A: Yes. All three connectors share identical connector style (D-Sub High Density), shell size (5 DD/D), position count (78), and mating interface specifications. They are mechanically and electrically compatible with the same 78-position D-Sub high-density plugs.

Q: What is the significance of the 0.350" backset spacing specification?

A: Backset spacing defines the distance from the mating face to the solder tail termination points on the printed circuit board. The HARTING and Amphenol ICC parts specify 0.350" (8.89mm) backset spacing. This parameter ensures proper board layout and component clearance during assembly and operation.

Q: Can the higher current rating of the Amphenol ICC part affect circuit performance?

A: No. The 3A current rating of the Amphenol ICC L77HDD78SD1CH4F represents the maximum current the connector can safely carry. Circuits designed for 2A operation will function identically. The higher rating provides design margin and supports potential future applications with increased current requirements.

Q: What packaging format are the substitute parts supplied in?

A: Both substitute parts are supplied in tray packaging, suitable for automated assembly processes and component handling.
