IL-Z-10S-S125C3 Equivalent & Substitute Parts

Part Overview

The IL-Z-10S-S125C3 is a 10-position rectangular connector housing manufactured by JAE Electronics. This receptacle housing accepts female socket contacts with a 0.049" (1.25mm) pitch and is designed for free-hanging in-line mounting applications using crimp termination. The part is classified as obsolete, making identification of active equivalent components essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IL-Z-10S-S125C3 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle housing with female socket contacts
• Position Count & Pitch: 10 positions at 0.049" (1.25mm) spacing
• Mounting & Termination: Free-hanging in-line mounting with crimp contact termination
• Insulation Material Class: Polyamide-based nylon construction

The DF13-10S-1.25C from Hirose Electric Co Ltd meets all these criteria. Both parts share identical functional specifications for position count, pitch, mounting style, and termination method. The substitute maintains compatibility with existing contact sets and PCB layouts designed for the IL-Z-10S-S125C3.

Parameter Comparison

Engineering Selection Recommendations

The DF13-10S-1.25C is the direct functional equivalent for the obsolete IL-Z-10S-S125C3. Selection of the Hirose substitute is supported by:

• Active Product Status: The DF13-10S-1.25C maintains current manufacturing and supply chain availability, eliminating procurement risk associated with the obsolete JAE part.
• Regulatory Compliance: The Hirose part carries ROHS3 compliance certification and REACH unaffected status, meeting modern environmental and regulatory requirements.
• Extended Operating Range: The DF13-10S-1.25C operates across -35°C ~ 85°C, providing a wider thermal envelope than the original part's -40°C ~ 70°C specification.
• Mechanical & Electrical Equivalence: Both housings accept identical 1.25mm pitch crimp contacts and maintain the same single-row, 10-position configuration for direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the DF13-10S-1.25C directly replace the IL-Z-10S-S125C3 in existing assemblies?

A: Yes. Both parts are 10-position receptacle housings with 0.049" (1.25mm) pitch, single-row configuration, and crimp termination. They accept the same contact geometry and mount identically in free-hanging in-line applications.

Q: What is the significance of the operating temperature difference?

A: The IL-Z-10S-S125C3 operates from -40°C ~ 70°C, while the DF13-10S-1.25C operates from -35°C ~ 85°C. The Hirose part provides extended high-temperature capability. For applications requiring -40°C operation, verify that the DF13-10S-1.25C's -35°C minimum meets system requirements.

Q: Are the insulation materials compatible?

A: Both parts use polyamide-based nylon insulation. The JAE part specifies PA66 glass-filled nylon, while the Hirose part specifies PA nylon. Both materials provide equivalent mechanical and electrical insulation properties for this connector class.

Q: What packaging is available for the DF13-10S-1.25C?

A: The DF13-10S-1.25C is supplied in bulk packaging with 580,200 pieces in current inventory.

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

A: The DF13-10S-1.25C carries ROHS3 compliance and REACH unaffected certification. The IL-Z-10S-S125C3 compliance status is not specified in the available data. Both parts are classified under ECCN EAR99 and HTSUS 8536.69.8000.
