Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 747548-5 is based on electrical and mechanical parameter equivalence within the TE Connectivity AMPLIMITE HDE-20 series. The substitute part must maintain identical specifications across the following critical parameters:

• Connector style and type (D-Sub receptacle with female sockets)
• Position count and row configuration (25 positions, 2 rows)
• Shell size and layout (Size 3, DB/B configuration)
• Termination method (IDC with discrete wire capability)
• Shell material and finish (Steel, tin plated)
• Contact material and finish (Phosphor bronze with gold flash)
• Voltage and temperature ratings (250V, -55°C ~ 105°C)
• Wire gauge compatibility (22-26 AWG)
• Shielding and backshell features

The substitute part 747548-9 satisfies all these parameters while offering the advantage of active product status and improved regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 747548-9 is the direct functional equivalent of the obsolete 747548-5. Both connectors share identical electrical and mechanical specifications, including connector configuration, termination method, material composition, and performance ratings. The 747548-9 offers the following advantages for component selection:

Product Status: The 747548-9 maintains active product status, ensuring long-term availability and continued manufacturer support, whereas the 747548-5 is obsolete and subject to discontinuation.

Regulatory Compliance: The 747548-9 is RoHS compliant and REACH unaffected, meeting current environmental and regulatory requirements. The 747548-5 is RoHS non-compliant with undefined REACH status, presenting potential compliance risks in new designs and procurement.

Inventory Availability: The 747548-9 is currently in stock with 697 units available, providing immediate procurement capability for production and service applications.

For applications currently using the 747548-5, direct substitution with the 747548-9 is supported without modification to connector interfaces, termination procedures, or electrical performance characteristics.

Frequently Asked Questions (FAQ)

Q: Are the 747548-5 and 747548-9 mechanically interchangeable?

A: Yes. Both connectors feature identical D-Sub shell size 3 (DB/B) configurations, free-hanging in-line mounting, and 25-position female socket receptacle designs. No mechanical modifications are required for substitution.

Q: Can the 747548-9 be used in applications originally designed for the 747548-5?

A: Yes. The 747548-9 maintains all electrical specifications of the 747548-5, including 250V voltage rating, -55°C ~ 105°C operating temperature range, and IDC termination compatibility with 22-26 AWG wire gauges. Direct substitution is supported.

Q: What is the difference between the packaging specifications?

A: The 747548-5 packaging is not specified in available documentation. The 747548-9 is supplied in bulk packaging. Packaging differences do not affect connector performance or compatibility.

Q: Why is RoHS compliance important for this substitution?

A: RoHS compliance is a regulatory requirement in many markets and industries. The 747548-9 is RoHS compliant, whereas the 747548-5 is non-compliant. For new designs and procurement in regulated environments, the 747548-9 is the appropriate selection.

Q: Are there any performance differences between these connectors?

A: No. Both connectors are manufactured by TE Connectivity within the AMPLIMITE HDE-20 series and share identical electrical and mechanical performance specifications. The primary differences are product status and regulatory compliance.

Q: What wire gauges are supported by the 747548-9?

A: The 747548-9 supports 22-26 AWG wire gauges for both IDC and discrete wire termination methods.

Q: Is the 747548-9 currently available for purchase?

A: Yes. The 747548-9 is an active product with 697 units in current inventory stock.
