The RJSAEJ38508 meets all required parameters for direct substitution, maintaining identical electrical and mechanical characteristics while offering active product status.

Parameter Comparison

Engineering Selection Recommendations

The RJSAEJ38508 is the designated substitute for the obsolete RJSNEJ38508. Both components comply with RoHS regulations and share identical MSL classifications. The RJSAEJ38508 maintains full electrical and mechanical compatibility across all specified parameters, with the additional advantage of active product status ensuring continued availability and manufacturing support.

The RJSAEJ38508 offers an extended lower operating temperature limit (-55°C versus -40°C), providing enhanced performance margins in demanding thermal environments. This characteristic presents no compatibility concerns for applications utilizing the original RJSNEJ38508 specification range.

Frequently Asked Questions (FAQ)

Q: Can RJSAEJ38508 replace RJSNEJ38508 in existing designs? A: Yes. The RJSAEJ38508 maintains full pin-to-pin and form-factor compatibility with identical contact configuration, termination method, shielding, and environmental ratings. PCB layouts and mechanical mounting require no modification.

Q: What is the significance of the -55°C lower temperature limit on the RJSAEJ38508? A: The RJSAEJ38508 specifies operation down to -55°C compared to the RJSNEJ38508 at -40°C. This extended range does not affect interchangeability; designs operating within -40°C to 85°C fall entirely within both specifications.

Q: Are there differences in LED color or tab orientation between these parts? A: No. Both connectors feature green LED color designation and identical up-and-down tab direction, ensuring consistent visual assembly and functional performance.

Q: What certifications apply to the RJSAEJ38508? A: The RJSAEJ38508 is RoHS compliant and carries MSL 1 (Unlimited) classification, matching the original RJSNEJ38508 environmental and regulatory compliance profile.

Q: Why is product status relevant for this substitution? A: The RJSNEJ38508 is obsolete, limiting future availability. The RJSAEJ38508, with active product status, ensures continued supply, manufacturing support, and cost stability for production quantities.
