IL-Y-11S-S15C3 Equivalent & Substitute Parts

Part Overview

The IL-Y-11S-S15C3 is an 11-position rectangular connector receptacle housing manufactured by JAE Electronics. This component features a 1.50mm pitch, crimp contact termination, and friction lock fastening. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IL-Y-11S-S15C3 is determined by the following critical parameters:

• Connector Type & Contact Configuration: Receptacle housing with female socket contacts
• Position Count & Pitch: 11 positions at 0.059" (1.50mm) spacing
• Mounting & Termination: Free hanging in-line configuration with crimp termination
• Insulation Material: Polyamide-based nylon construction
• Moisture Sensitivity: MSL 1 rating

The substitute part 0874391100 (Molex Pico-SPOX 87439) satisfies all critical substitution criteria. While fastening mechanism differs (locking ramp versus friction lock), both designs accommodate the same contact interface and pitch geometry, permitting functional equivalence in applications where the housing interface is the primary selection criterion.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0874391100 is the qualified substitute for the obsolete JAE IL-Y-11S-S15C3. Selection rationale:

• Product Status: The substitute is active production, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: The Molex part carries ROHS3 compliance and REACH unaffected status, meeting current environmental regulations.
• Functional Equivalence: All critical electrical and mechanical parameters align, including pitch, position count, contact type, and termination method.
• Operating Range: The substitute specifies -55°C ~ 105°C operating temperature, providing defined thermal performance.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0874391100 directly replace the JAE IL-Y-11S-S15C3 in existing designs?

A: Yes. Both housings accommodate 11 crimp contacts at 1.50mm pitch in a single-row, free-hanging configuration. The fastening mechanism difference (locking ramp versus friction lock) does not prevent functional substitution at the housing interface level.

Q: What is the significance of the fastening type difference?

A: Fastening type affects mating force and retention characteristics. Friction lock and locking ramp designs provide different mechanical engagement profiles. Verify mating connector compatibility with the substitute fastening mechanism in your specific application.

Q: Are the insulation materials compatible?

A: Both parts use polyamide-based nylon construction. The JAE part specifies PA66 (Nylon 6/6), while the Molex part specifies PA (Nylon). Both materials provide equivalent electrical and mechanical properties for this connector class.

Q: What is the impact of color difference (Brown versus Natural)?

A: Color is a cosmetic attribute and does not affect electrical or mechanical function. Selection depends on application requirements and assembly identification standards.

Q: Does the Molex part require different contact specifications?

A: Both housings accept crimp contacts at 1.50mm pitch. Verify that contact part numbers are compatible with the Molex housing series. Contacts are not included with either housing.

Q: Is the operating temperature specification important for substitution?

A: The Molex part specifies -55°C ~ 105°C operating range. If your application requires temperature performance verification, this specification provides defined limits. The JAE part does not specify operating temperature.
