• Number of positions: 25
• Number of rows: 2
• Shell size and layout: 3 (DB, B)
• Mounting type: Free Hanging (In-Line)
• Termination type: IDC, Discrete Wire
• Shell material and finish: Steel, Tin Plated
• Contact finish: Gold, Flash thickness
• Voltage rating: 250V
• Operating temperature range: -55°C ~ 105°C
• Wire gauge compatibility: 22-26 AWG
• Contact material: Phosphor Bronze
• Dielectric material: Thermoplastic
• Features: Backshell, Grounding Indents, Shielded
• Material flammability rating: UL94 V-0

The substitute part 1-747547-0 meets all mandatory matching parameters and is therefore a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1-747547-0 is a direct functional equivalent to the 747547-5 across all electrical and mechanical parameters. Selection between these parts should be based on the following factors:

Product Status Consideration: The 747547-5 is obsolete, while 1-747547-0 is active. For new designs and ongoing production, 1-747547-0 is the appropriate selection to ensure long-term availability and supply chain continuity.

Regulatory Compliance: The 1-747547-0 is ROHS3 compliant and carries a defined REACH Unaffected status, compared to the 747547-5 which is RoHS non-compliant with vendor-undefined REACH status. Applications subject to RoHS3 or REACH regulations require the 1-747547-0.

Packaging Difference: The 747547-5 is supplied in standard packaging, while 1-747547-0 is supplied in bulk packaging. Packaging selection depends on order quantity and inventory management requirements.

Functional Interchangeability: Both parts are electrically and mechanically interchangeable. They share identical connector geometry, pin configuration, contact materials, and electrical ratings. No circuit redesign or mechanical modification is required when substituting 747547-5 with 1-747547-0.

Frequently Asked Questions (FAQ)

Q: Can 1-747547-0 be used as a direct replacement for 747547-5 in existing applications?

A: Yes. The 1-747547-0 is a direct functional equivalent. All electrical parameters, mechanical dimensions, contact configurations, and performance characteristics are identical. No modifications to circuits, PCBs, or mechanical assemblies are required.

Q: What is the difference between these two part numbers?
