IL-Z-6S-S125C3 Equivalent & Substitute Parts

Part Overview

The IL-Z-6S-S125C3 is a 6-position rectangular connector housing manufactured by JAE Electronics with a 1.25mm pitch. This receptacle connector is designed for free-hanging in-line applications with crimp contact termination and friction lock fastening. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IL-Z-6S-S125C3 is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Receptacle housing with female socket contacts
• Position Count & Pitch: 6 positions at 0.049" (1.25mm) pitch
• Row Configuration: Single row layout
• Mounting & Termination: Free hanging in-line mounting with crimp contact termination
• Electrical & Environmental Compliance: Operating temperature range and moisture sensitivity classification

The DF13-6S-1.25C from Hirose Electric Co Ltd meets all substitution criteria. Both connectors share identical position count, pitch spacing, receptacle configuration, and crimp termination method. The substitute maintains compatibility with existing contact sets and PCB layouts designed for the IL-Z-6S-S125C3.

Engineering Selection Recommendations

The DF13-6S-1.25C is a direct functional substitute for the IL-Z-6S-S125C3. Selection of the Hirose part is supported by:

• Active Product Status: The DF13-6S-1.25C maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete IL-Z-6S-S125C3.
• Compliance Certifications: The substitute meets RoHS3 compliance and REACH unaffected status, providing regulatory alignment for current manufacturing standards.
• Enhanced Operating Range: The DF13-6S-1.25C operates across -35°C ~ 85°C, exceeding the original -40°C ~ 70°C specification and providing additional thermal margin for demanding applications.
• Identical Mechanical Interface: Matching pitch, position count, and mounting configuration ensure direct replacement without PCB redesign or contact set modification.

Frequently Asked Questions (FAQ)

Q: Can the DF13-6S-1.25C directly replace the IL-Z-6S-S125C3 without PCB modification?

A: Yes. Both connectors share identical pitch (1.25mm), position count (6), row configuration (1), and mounting type (free hanging in-line). Existing contact sets and PCB footprints designed for the IL-Z-6S-S125C3 are compatible with the DF13-6S-1.25C.

Q: What is the primary reason for substitution?

A: The IL-Z-6S-S125C3 is obsolete. The DF13-6S-1.25C is an active product from Hirose Electric Co Ltd, ensuring availability for new production runs and system maintenance.

Q: Are there differences in insulation material between the two connectors?

A: The IL-Z-6S-S125C3 uses polyamide (PA66) with glass filling, while the DF13-6S-1.25C uses polyamide (PA) nylon. Both materials provide equivalent electrical insulation and mechanical performance for this connector class.

Q: Does the substitute offer improved environmental performance?

A: Yes. The DF13-6S-1.25C operates across -35°C ~ 85°C compared to the original -40°C ~ 70°C range. Both connectors maintain MSL 1 (unlimited moisture sensitivity classification).

Q: What packaging format is available for the substitute?

A: The DF13-6S-1.25C is supplied in bulk packaging, with 954 pieces currently in stock as new original inventory.

Q: Are contact sets interchangeable between the two housings?

A: Yes. Both connectors use crimp contact termination with identical pitch spacing. Contact sets designed for the IL-Z-6S-S125C3 are compatible with the DF13-6S-1.25C housing.
