IL-7S-S3L-(N) Equivalent & Substitute Parts
Part Overview
The IL-7S-S3L-(N) is a 7-position rectangular connector housing manufactured by JAE Electronics. This receptacle connector features a 2.50mm pitch and is designed for free-hanging in-line mounting applications with crimp contact termination and friction lock fastening. The part maintains Active product status with full RoHS compliance and unlimited moisture sensitivity rating.
Substitute parts become necessary when the IL-7S-S3L-(N) experiences supply constraints, inventory depletion, or when design flexibility permits alternative connector housings that maintain electrical and mechanical compatibility within the specified parameter range.

Substitute Part Grouping Explanation
Substitution eligibility for the IL-7S-S3L-(N) is determined by strict alignment with the following critical parameters:
- 7-position receptacle housing configuration
- 2.50mm (0.098") contact pitch
- Single-row arrangement
- Female socket contact type
- Crimp termination capability
- Friction lock fastening mechanism
- Free-hanging in-line mounting compatibility
- RoHS compliance status
The substitute part 0511020700 (Molex Mini-Lock 51102 series) satisfies all mandatory electrical and mechanical parameters. Variations in insulation material composition and color do not affect functional substitution within the specified parameter constraints.

Engineering Selection Recommendations
The IL-7S-S3L-(N) maintains Active product status with established supply availability (807 pcs in stock). This part is the primary selection for new designs and ongoing production.
The 0511020700 (Molex Mini-Lock 51102) qualifies as a functional equivalent based on matching electrical and mechanical parameters. However, this part carries Obsolete product status, indicating discontinued manufacturing and limited future availability. Selection of this substitute should be restricted to legacy system maintenance or applications where supply of the primary part is unavailable.
Both parts maintain RoHS compliance and unlimited moisture sensitivity ratings, ensuring regulatory and environmental compatibility. The insulation material difference (PA66 versus PBTP) and operating temperature specification do not affect substitution eligibility within the defined parameter constraints.
Frequently Asked Questions (FAQ)
Q: What determines if a part can substitute for the IL-7S-S3L-(N)?
A: Substitution requires matching the 7-position, 2.50mm pitch receptacle configuration with female socket contacts, crimp termination, friction lock fastening, and free-hanging in-line mounting. All electrical and mechanical parameters must align exactly.
Q: Can the 0511020700 be used in place of the IL-7S-S3L-(N)?
A: Yes. The 0511020700 satisfies all mandatory electrical and mechanical parameters. However, the Obsolete product status of the Molex part limits its suitability to applications where primary part availability is constrained.
Q: Does the color difference between Brown (IL-7S-S3L-(N)) and White (0511020700) affect compatibility?
A: Color is a cosmetic attribute and does not affect electrical or mechanical function. Substitution is valid from a technical standpoint, though design specifications may require color matching.
Q: Are the insulation materials interchangeable?
A: Both Polyamide (PA66) and Polybutylene Terephthalate (PBTP) are standard insulation materials for rectangular connectors in this category. The material difference does not prevent functional substitution within the specified parameter range.
Q: What is the significance of the Obsolete status for the 0511020700?
A: Obsolete status indicates the manufacturer has discontinued production. This part should be selected only when the primary IL-7S-S3L-(N) is unavailable. Long-term supply reliability cannot be assured for obsolete components.
Q: Do both parts require separate contact components?
A: Yes. Both the IL-7S-S3L-(N) and 0511020700 are housings only. Contacts are not included and must be sourced separately according to the connector series specifications.
