Key Parameters

Substitute Part Grouping Explanation

The substitute part 5-747905-2 is classified as a direct equivalent to 747905-8 based on the following critical parameters that determine substitution compatibility:

Electrical Parameters:

• Identical connector type (Receptacle, Female Sockets)
• Identical position count (9 positions, 2 rows)
• Identical shell size and layout (1 DE, E)
• Identical current rating (3A)
• Identical voltage rating (250V)
• Identical operating temperature range (-55°C to 105°C)

Mechanical Parameters:

• Identical termination method (Solder Cup)
• Identical mounting type (Free Hanging, In-Line)
• Identical shell material and finish (Steel, Tin Plated)
• Identical contact material and finish (Brass with Gold Flash)
• Identical dielectric material (PBT, Glass Filled)
• Identical flange feature (Unthreaded Housing/Shell)

Compliance Parameters:

• Identical material flammability rating (UL94 V-0)
• Identical moisture sensitivity level (MSL 1)

The primary distinction between these parts is product status and packaging configuration. The 747905-8 is obsolete with limited inventory, while 5-747905-2 is an active product with significantly higher stock availability and improved RoHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: 5-747905-2

The substitute part 5-747905-2 is the recommended selection for new designs and procurement activities. This part maintains complete electrical and mechanical compatibility with 747905-8 while offering the following advantages:

• Active product status ensures long-term availability and manufacturing support
• ROHS3 compliance status provides regulatory alignment for current and future applications
• Significantly higher inventory availability (473,277 units) supports production schedules and supply chain continuity
• Tray packaging configuration supports automated assembly processes and inventory management

Secondary Consideration: 747905-8

The original part 747905-8 remains functionally equivalent for applications where existing inventory is available. However, the obsolete product status and limited stock (819 units) restrict its use to legacy system maintenance or repair applications where component continuity is required. The lack of RoHS3 compliance may present regulatory constraints in certain markets or applications.

Compatibility Assurance

Both parts are manufactured by TE Connectivity within the AMPLIMITE HD-20 series and share identical electrical ratings, mechanical dimensions, and material specifications. Direct substitution is supported without circuit redesign or mechanical modification.

Frequently Asked Questions (FAQ)

Q: Can 5-747905-2 be used as a direct replacement for 747905-8 in existing designs?

A: Yes. The 5-747905-2 is electrically and mechanically identical to 747905-8. All electrical parameters (current rating, voltage rating, operating temperature), mechanical specifications (connector type, position count, shell size, termination method), and material properties are identical. Direct substitution requires no circuit modification or mechanical redesign.

Q: What is the difference between the packaging of these two parts?

A: The 747905-8 is supplied in bulk packaging, while the 5-747905-2 is supplied in tray packaging. Tray packaging provides improved handling, inventory tracking, and compatibility with automated assembly equipment. Both packaging formats contain the same connector component with identical electrical and mechanical properties.

Q: Why is 747905-8 classified as obsolete?

A: The 747905-8 has been superseded by the 5-747905-2 in the manufacturer's product line. The substitute part offers improved compliance status (ROHS3) and maintains active manufacturing support. Obsolete classification indicates that the original part is no longer in active production, though existing inventory may remain available for a limited period.

Q: Does the RoHS3 compliance difference affect electrical performance?

A: No. RoHS3 compliance is a regulatory and material composition specification that does not alter electrical performance or functional characteristics. Both parts meet identical electrical ratings and operating specifications. The RoHS3 compliance of 5-747905-2 provides regulatory alignment for applications subject to European Union directives and similar international standards.

Q: Are the solder cup terminations identical between these parts?

A: Yes. Both parts feature identical solder cup termination specifications. The solder cup design, material composition, and electrical characteristics are the same. Both parts support identical soldering processes and wire gauge compatibility.

Q: Can these connectors be used interchangeably in mating applications?

A: Yes. Both parts are 9-position D-Sub receptacles with identical shell size (1 DE, E), pin configuration, and mechanical dimensions. They mate with standard D-Sub plugs designed for 9-position DE-series connectors. No mechanical or electrical modifications are required for interchangeability.

Q: What is the significance of the gold flash contact finish?

A: The gold flash finish provides corrosion resistance and reliable electrical contact over the operating temperature range (-55°C to 105°C). This finish is identical on both parts and ensures consistent contact resistance and signal integrity throughout the connector's service life.

Q: Are there any temperature or environmental limitations for these connectors?

A: Both parts operate within the identical temperature range of -55°C to 105°C and maintain UL94 V-0 flammability rating. The moisture sensitivity level (MSL 1) indicates unlimited shelf life without special storage requirements. No additional environmental limitations apply beyond these specifications.
