IL-Z-8S-S125C3 Equivalent & Substitute Parts
Part Overview
The IL-Z-8S-S125C3 is an 8-position rectangular connector receptacle housing manufactured by JAE Electronics with a 1.25mm pitch. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The connector features a single-row configuration with crimp contact termination and friction lock fastening, designed for free-hanging in-line mounting applications.

Substitute Part Grouping Explanation
Substitute parts for the IL-Z-8S-S125C3 are qualified based on the following critical parameters that ensure functional and mechanical compatibility:
- Connector Type & Contact Configuration: Receptacle housing with female socket contacts
- Position Count & Pitch: 8 positions at 0.049" (1.25mm) pitch
- Row Configuration: Single-row layout
- Mounting & Termination: Free-hanging in-line mounting with crimp contact termination
- Environmental Rating: Moisture Sensitivity Level 1 (Unlimited)
The substitute parts listed below meet all these core parameters and are therefore electrically and mechanically interchangeable with the original component.

Engineering Selection Recommendations
Both substitute parts are qualified replacements for the obsolete IL-Z-8S-S125C3 based on matching electrical and mechanical parameters.
DF13-8S-1.25C (Hirose Electric) is an active product with extended operating temperature range (-35°C ~ 85°C) and carries ROHS3 compliance and REACH Unaffected status. This part is suitable for applications requiring active product support and regulatory compliance documentation.
0511460800 (Molex PanelMate 51146) is an active product with the widest operating temperature range (-40°C ~ 85°C) and friction lock fastening matching the original specification. This part carries ROHS3 compliance and REACH Unaffected status. The PBT insulation material and extended temperature range make this option suitable for demanding thermal environments.
Both parts maintain MSL 1 rating and crimp termination compatibility with the original component.
Frequently Asked Questions (FAQ)
Q: Are these substitute parts mechanically compatible with the IL-Z-8S-S125C3?
A: Yes. Both substitute parts share identical connector type, position count, pitch (1.25mm), row configuration, and mounting style. They are mechanically interchangeable.
Q: What is the difference in operating temperature ranges?
A: The original IL-Z-8S-S125C3 operates from -40°C to 70°C. The DF13-8S-1.25C operates from -35°C to 85°C, and the 0511460800 operates from -40°C to 85°C. For applications exceeding 70°C, either substitute part is suitable.
Q: Do these parts require different contact pins?
A: All three parts use crimp contact termination at 1.25mm pitch. Contact compatibility depends on the specific pin design of your mating connector, not the housing manufacturer. Verify contact specifications with your connector supplier.
Q: What is the packaging difference?
A: The original IL-Z-8S-S125C3 packaging is not specified. Both substitute parts are supplied in bulk packaging, which is standard for connector housings.
Q: Are there compliance or certification differences?
A: The DF13-8S-1.25C and 0511460800 both carry ROHS3 compliance and REACH Unaffected status. The original part status is not specified for these certifications. For applications requiring regulatory documentation, the active substitute parts provide current compliance records.
Q: Which substitute part should I select?
A: Selection depends on your application requirements. For maximum temperature range and friction lock fastening matching the original specification, select 0511460800. For active product support with extended temperature capability, select DF13-8S-1.25C. Both are electrically and mechanically equivalent.
