Engineering Selection Recommendations
The RTTC34B01X is the appropriate selection for applications currently specified with RTTC34B01. The substitute part maintains complete electrical and mechanical compatibility while offering two significant advantages:
- Active product status ensures continued availability and manufacturing support
- ROHS3 compliance and improved moisture sensitivity rating (MSL 1) provide enhanced regulatory alignment and environmental performance
No functional or performance degradation results from this substitution. The parts are electrically and mechanically interchangeable for all specified applications.
Frequently Asked Questions (FAQ)
Q: Are RTTC34B01 and RTTC34B01X electrically interchangeable?
A: Yes. Both parts feature identical signal line configuration (3 Conductor, TRS), contact count (5 Contacts), contact material (Copper Alloy with Gold plating), and operating temperature range (-55°C to 85°C).
Q: What are the mechanical compatibility requirements?
A: Both connectors share identical mounting specifications: through-hole, right-angle orientation with solder termination. The mating diameter (4.39mm) and actual diameter (4.48mm) are identical, ensuring mechanical fit in existing designs.
Q: Why is RTTC34B01X preferred over RTTC34B01?
A: The RTTC34B01X offers active product status with continued manufacturing support, ROHS3 compliance, and MSL 1 rating, whereas RTTC34B01 is obsolete and RoHS non-compliant.
Q: Are there packaging differences between these parts?
A: RTTC34B01 is supplied with cover packaging, while RTTC34B01X is supplied in bulk packaging. Both include the connector and cover as specified.
Q: Can RTTC34B01X be used in new designs?
A: Yes. The active product status and improved compliance profile make RTTC34B01X suitable for new design implementations.
