Substitute Part Grouping Explanation

The substitute part RJE081880110 (Amphenol ICC) is identified as a functional equivalent based on the following substitution criteria:

Primary Substitution Basis:

• Both components belong to the modular connector category
• Both are jack-type modular connectors
• Both share identical HTSUS classification (8536.69.4040)
• Both maintain MSL Level 1 (Unlimited) moisture sensitivity rating
• Both comply with REACH regulations and EAR99 export classification

The RJE081880110 represents an active, currently manufactured alternative to the obsolete SS-71800-025, providing continuity for applications requiring modular jack connector functionality.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement: The RJE081880110 is the designated substitute for the SS-71800-025. Selection of this alternative is based on:

• Active product status ensuring long-term availability and supply chain continuity
• Compliance with RoHS regulations, exceeding the REACH Unaffected status of the original part
• Identical export classification (EAR99) and tariff coding (HTSUS 8536.69.4040)
• Matching MSL Level 1 rating for moisture sensitivity
• Significantly higher inventory availability (4992 units vs. 977 units)

Compatibility Verification: Before implementation, confirm that the specific connector configuration of the RJE081880110 (8p8c vertical through-hole solder termination, unshielded) aligns with the mechanical and electrical requirements of the original application. The detailed specifications of the SS-71800-025 should be cross-referenced with the RJE081880110 datasheet to ensure form factor, pin count, and termination method compatibility.

Frequently Asked Questions (FAQ)

Q: Why is the SS-71800-025 listed as obsolete? A: The SS-71800-025 has reached end-of-life status with the manufacturer. While current inventory remains available (977 units), no new production is planned. The RJE081880110 provides functional continuity for ongoing applications.

Q: What are the key parameters that make RJE081880110 a valid substitute? A: Both components are modular jack connectors sharing identical HTSUS classification, MSL rating, and export compliance codes. The RJE081880110 is an active product with superior availability and RoHS compliance.

Q: Are there mechanical compatibility concerns between these parts? A: The SS-71800-025 specifications are partially undocumented in this reference. The RJE081880110 is specified as an 8p8c (RJ45) vertical through-hole connector. Physical compatibility must be verified against the original part's mechanical drawing and the target application's connector footprint.

Q: What is the difference in packaging between these parts? A: The RJE081880110 is supplied in tray packaging. Confirm that tray packaging meets your procurement and assembly requirements, as the original SS-71800-025 packaging format is not specified.

Q: Are there compliance differences I should consider? A: The RJE081880110 carries RoHS Compliant certification, providing enhanced environmental compliance compared to the REACH Unaffected status of the SS-71800-025. Both maintain EAR99 export classification.

Q: What is the operating temperature range for the substitute? A: The RJE081880110 operates across -40°C to 70°C. Verify this range meets your application requirements, as the original part's operating temperature is not specified.
