Key Parameters

Substitute Part Grouping Explanation

Substitution of the IL-Z-9S-S125C3 is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (9)
• Pitch specification (0.049" / 1.25mm)
• Number of rows (1)
• Mounting configuration (Free Hanging / In-Line)
• Contact termination method (Crimp)
• Fastening mechanism (Friction Lock)

The Molex 0511460900 satisfies all these requirements and qualifies as a parametric equivalent. Variations in insulation material (PBT versus PA66) and operating temperature range (-40°C ~ 85°C versus -40°C ~ 70°C) do not preclude substitution, as the substitute part meets or exceeds the original specifications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0511460900 is the qualified substitute for the obsolete IL-Z-9S-S125C3. The substitute part maintains functional and mechanical equivalence across all critical connector parameters. The Molex component offers the additional advantage of active product status, ensuring continued availability and supply chain stability.

The substitute part exceeds the original operating temperature specification (-40°C ~ 85°C versus -40°C ~ 70°C) and carries ROHS3 compliance and REACH unaffected status, providing enhanced regulatory alignment for new designs and system upgrades.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0511460900 be used as a direct replacement for the IL-Z-9S-S125C3?

A: Yes. Both connectors share identical specifications for connector type, contact type, position count, pitch, mounting configuration, termination method, and fastening mechanism. The substitute part meets all functional and mechanical requirements for direct substitution.

Q: What is the difference in insulation material between the two parts?

A: The IL-Z-9S-S125C3 uses polyamide (PA66) with glass filling, while the Molex 0511460900 uses polybutylene terephthalate (PBT). Both materials are suitable for the specified operating temperature range of the original part.

Q: Does the higher operating temperature range of the substitute part affect compatibility?

A: No. The Molex part's extended operating range (-40°C ~ 85°C) exceeds the original specification (-40°C ~ 70°C), ensuring compatibility across all intended operating conditions of the original design.

Q: Are there any compliance differences between the two parts?

A: The Molex 0511460900 carries ROHS3 compliance and REACH unaffected status. These certifications provide regulatory advantages for applications requiring environmental compliance documentation.

Q: What packaging is available for the substitute part?

A: The Molex 0511460900 is supplied in bulk packaging, with 17,726 pieces available in current inventory.
