Engineering Selection Recommendations
Both MTJ-88EX1 and MTJ-88EX2 are active production parts with ROHS3 compliance and REACH unaffected status. Selection between these parts depends on operating temperature requirements. The MTJ-88EX1 supports the full temperature range of -40°C to 125°C, while the MTJ-88EX2 operates within -40°C to 85°C. For applications requiring operation above 85°C, the MTJ-88EX1 is the appropriate selection. For applications within the -40°C to 85°C range, either part is functionally equivalent. Both parts carry identical electrical and mechanical specifications for connector interface, contact material, and termination method.
Frequently Asked Questions (FAQ)
Q: Can MTJ-88EX2 be used as a direct replacement for MTJ-88EX1?
A: MTJ-88EX2 is functionally equivalent to MTJ-88EX1 for applications operating within the -40°C to 85°C temperature range. Both parts share identical connector type, contact configuration, mounting method, and termination specifications. Selection depends on your application's maximum operating temperature requirement.
Q: What is the primary difference between MTJ-88EX1 and MTJ-88EX2?
A: The primary difference is the operating temperature range. MTJ-88EX1 operates from -40°C to 125°C, while MTJ-88EX2 operates from -40°C to 85°C. All other electrical and mechanical parameters are identical.
Q: Are both parts suitable for Ethernet applications?
A: Yes. Both MTJ-88EX1 and MTJ-88EX2 are 8P8C (RJ45) modular jack connectors designed for Ethernet and network connectivity. They share identical contact configuration and electrical interface specifications.
Q: Do these connectors require shielding?
A: Both parts are unshielded connectors. If shielded performance is required, alternative connector designs must be evaluated.
Q: What is the packaging format for these parts?
A: Both MTJ-88EX1 and MTJ-88EX2 are supplied in tray packaging.
Q: Are there any compliance differences between the two parts?
A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8536.69.4040).
