Key Parameters

Substitute Part Grouping Explanation

The RJSAEJ38108 qualifies as a direct substitute for the RJSNEJ38108 based on the following critical parameters that define electrical and mechanical compatibility:

Key Substitution Criteria:

• Identical connector type and contact configuration (8p8c RJ45, Ethernet)
• Matching orientation (90° right-angle)
• Equivalent shielding design (Shielded with EMI Finger)
• Same mounting methodology (Through Hole, Solder)
• Identical contact materials and finish specifications (Phosphor Bronze, Gold 30.0µin)
• Matching operating temperature capability (-55°C ~ 85°C for substitute exceeds original -40°C ~ 85°C)
• Compatible environmental classifications (RoHS Compliant, MSL 1)

The substitution is valid because the RJSAEJ38108 maintains all electrical and mechanical characteristics required for direct form, fit, and function replacement in applications where the RJSNEJ38108 was originally specified.

Parameter Comparison

Engineering Selection Recommendations

The RJSAEJ38108 is the appropriate substitute for the RJSNEJ38108 in new designs and long-term applications. The original part (RJSNEJ38108) carries Obsolete product status, indicating discontinued manufacturing and potential supply limitations. The substitute maintains full RoHS Compliance and MSL 1 classification, ensuring compatibility with modern manufacturing processes and long-term storage requirements. The extended operating temperature range of the substitute (-55°C ~ 85°C versus -40°C ~ 85°C) provides enhanced thermal margin for demanding applications. Both parts share identical electrical and mechanical specifications, supporting direct replacement without circuit board redesign or component reworking.

Frequently Asked Questions (FAQ)

Q: Can the RJSAEJ38108 replace the RJSNEJ38108 in existing assemblies? A: Yes. The RJSAEJ38108 provides direct form, fit, and function equivalence. All electrical characteristics, physical dimensions, mounting interfaces, and termination specifications are identical. Existing circuit board layouts and assembly processes require no modification.

Q: What are the key compatibility parameters for this substitution? A: The critical parameters are connector type (8p8c RJ45 Jack), orientation (90° right-angle), shielding method (EMI finger), mounting approach (through-hole solder), contact specifications (Phosphor Bronze with 30.0µin gold finish), and operating temperature capability. The RJSAEJ38108 satisfies all these requirements.

Q: Why is the original RJSNEJ38108 being replaced? A: The RJSNEJ38108 has reached Obsolete status, indicating the manufacturer has discontinued production. The RJSAEJ38108 is from an active product series (RJSAE) with established supply availability, making it the preferred choice for continued component sourcing.

Q: Are there any compliance or environmental differences? A: No. Both parts carry RoHS Compliance certification and maintain MSL 1 (Unlimited) moisture sensitivity classification. The regulatory coding (ECCN and HTSUS) is identical.

Q: Does the substitute offer any performance improvements? A: The substitute extends the operating temperature range to -55°C, compared to the original -40°C lower limit. This provides additional thermal margin for applications in demanding environmental conditions. All other electrical and mechanical characteristics remain equivalent.
