IL-Z-13S-S125C3 Equivalent & Substitute Parts

Part Overview

The IL-Z-13S-S125C3 is a 13-position rectangular connector receptacle housing manufactured by JAE Electronics, designed for 0.049" (1.25mm) pitch applications with crimp contact termination and friction lock fastening. This connector is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, repair, and new design implementations where the original part is no longer readily available through standard distribution channels.

Substitute Part Grouping Explanation

Substitution of the IL-Z-13S-S125C3 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle housing with female socket contacts
• Position Count & Pitch: 13 positions at 0.049" (1.25mm) pitch
• Mechanical Interface: Single-row, free-hanging in-line mounting with friction lock fastening
• Electrical Interface: Crimp contact termination compatible with 1.25mm pitch contact systems
• Environmental Compliance: Moisture sensitivity level 1 and applicable regulatory classifications

The Molex 0510211300 (PicoBlade 51021 series) satisfies all mandatory substitution criteria. Both parts share identical position count, pitch, mounting configuration, contact termination method, and fastening mechanism. Differences in insulation material (PA66 versus PBTP) and operating temperature range do not preclude substitution when the application environment remains within the IL-Z-13S-S125C3 specification limits.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0510211300 is the direct functional equivalent for the obsolete IL-Z-13S-S125C3. Selection of the Molex substitute is supported by:

• Product Availability: The Molex part maintains active production status with substantial inventory availability (7422 pcs), ensuring supply chain continuity.
• Regulatory Compliance: Both parts share identical ECCN (EAR99) and HTSUS classifications. The Molex part carries ROHS3 compliance and REACH unaffected status, meeting current environmental and trade regulations.
• Mechanical & Electrical Compatibility: Identical pitch, position count, mounting configuration, contact termination, and fastening mechanism ensure direct substitution without redesign.
• Operating Environment: Applications operating within the IL-Z-13S-S125C3 temperature range (-40°C to 70°C) are fully supported by the Molex alternative, which provides extended temperature capability to 105°C.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0510211300 be used as a direct replacement for the IL-Z-13S-S125C3 in existing assemblies?

A: Yes. Both connectors share identical pitch (0.049" / 1.25mm), position count (13), mounting type (free-hanging in-line), contact termination (crimp), and fastening mechanism (friction lock). No mechanical or electrical redesign is required.

Q: What is the difference in insulation material between these two parts?

A: The IL-Z-13S-S125C3 uses glass-filled polyamide (PA66/Nylon 6/6), while the Molex 0510211300 uses polybutylene terephthalate (PBTP). Both materials are suitable for the specified operating temperature range of the original part and provide equivalent moisture resistance (MSL 1).

Q: Does the Molex part support the same contact types and termination method?

A: Yes. Both parts are receptacle housings with female socket contacts and crimp termination. Contacts must be sourced separately for both parts and must be compatible with the 1.25mm pitch specification.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts share the same ECCN (EAR99) and HTSUS (8536.69.8000) classifications. The Molex part carries additional certifications: ROHS3 compliance and REACH unaffected status, which may be required for certain applications or markets.

Q: What is the inventory status for each part?

A: The IL-Z-13S-S125C3 has 862 pcs available as new original stock. The Molex 0510211300 has 7422 pcs available, providing significantly greater supply availability for ongoing production and repair requirements.

Q: Can these connectors be used in applications exceeding 70°C?

A: The IL-Z-13S-S125C3 is rated to 70°C maximum. The Molex 0510211300 extends to 105°C. For applications requiring operation above 70°C, the Molex part provides additional thermal margin, though this exceeds the original part specification.
