Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IL-Z-11S-S125C3 is determined by strict alignment of the following critical parameters:

• Connector Type: Receptacle housing only
• Contact Type: Female socket configuration
• Number of Positions: 11 positions
• Pitch: 0.049" (1.25mm) spacing
• Number of Rows: Single row configuration
• Mounting Type: Free hanging in-line mounting
• Contact Termination: Crimp termination method
• Insulation Material: Polyamide or Nylon-based materials

The DF13-11S-1.25C from Hirose Electric Co Ltd meets all substitution criteria. This part maintains identical electrical and mechanical specifications while offering active product status and enhanced operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The DF13-11S-1.25C serves as the direct functional equivalent for the obsolete IL-Z-11S-S125C3. Selection of the Hirose alternative is supported by:

• Identical mechanical and electrical specifications across all critical parameters
• Active product status ensuring long-term availability and supply chain continuity
• ROHS3 compliance and REACH unaffected status meeting current regulatory requirements
• Extended operating temperature range (-35°C ~ 85°C) providing broader application flexibility compared to the original part (-40°C ~ 70°C)
• Equivalent moisture sensitivity classification (MSL 1) ensuring identical handling and storage requirements

Frequently Asked Questions (FAQ)

Q: Can the DF13-11S-1.25C be used as a direct replacement for the IL-Z-11S-S125C3?

A: Yes. Both parts are 11-position receptacle housings with 1.25mm pitch, crimp termination, and single-row in-line mounting. All critical mechanical and electrical parameters are identical.

Q: What is the difference in operating temperature range between these parts?

A: The IL-Z-11S-S125C3 operates from -40°C to 70°C, while the DF13-11S-1.25C operates from -35°C to 85°C. The Hirose part provides a wider upper temperature limit, though the JAE part extends 5°C lower on the minimum end.

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

A: The DF13-11S-1.25C carries ROHS3 compliance and REACH unaffected status. The IL-Z-11S-S125C3 specifications do not include these certifications. Both parts share MSL 1 classification.

Q: Does the color difference affect substitution?

A: The DF13-11S-1.25C is specified as beige, while the IL-Z-11S-S125C3 color is not specified. Color does not affect electrical or mechanical function for this connector type.

Q: Are contacts included with either part?

A: No. Both the IL-Z-11S-S125C3 and DF13-11S-1.25C are housing-only components. Contacts must be sourced separately.
