Substitute Part Grouping Explanation
Substitution eligibility for the CT2944-50 is determined by the following critical parameters:
- Connector Style & Type: BNC jack-to-plug adapter configuration
- Impedance: 50 ohms (mandatory for RF signal integrity)
- Mounting Configuration: Free hanging (in-line) form factor
- Material Composition: Brass body with nickel finish, beryllium copper contacts with gold finish
- Dielectric Material: PTFE insulation
- Compliance Standards: ROHS3 compliance and REACH unaffected status
The CT2944C-50 qualifies as a substitute based on matching all core electrical and mechanical parameters. The primary distinction is product status (active vs. obsolete) and maximum frequency rating.

Engineering Selection Recommendations
The CT2944C-50 is the designated substitute for the obsolete CT2944-50. Both components maintain identical mechanical form factors, electrical impedance specifications, and material compositions. The CT2944C-50 carries active product status with current manufacturing support and inventory availability (1136 pcs in stock).
Selection of the CT2944C-50 is supported by:
- Matching 50-ohm impedance for RF circuit compatibility
- Identical BNC jack-to-plug adapter configuration
- Equivalent material specifications (brass body, beryllium copper contacts, gold finish, PTFE dielectric)
- ROHS3 compliance certification on both parts
- Active product status ensuring continued availability and supply chain reliability
The frequency rating difference (2 GHz vs. 1 GHz maximum) should be evaluated against specific application requirements. Applications operating below 1 GHz encounter no operational constraints with the substitute part.
Frequently Asked Questions (FAQ)
Q: Can CT2944C-50 be used as a direct replacement for CT2944-50?
A: Yes. Both parts share identical connector style, impedance, mounting configuration, and material specifications. The CT2944C-50 is the active production equivalent.
Q: What is the significance of the frequency rating difference?
A: The CT2944-50 supports operation to 2 GHz, while the CT2944C-50 supports operation to 1 GHz. For applications operating at frequencies below 1 GHz, this difference has no impact on performance. Applications requiring operation above 1 GHz must retain the original CT2944-50 specification or identify alternative components rated for higher frequencies.
Q: Are there packaging differences between these parts?
A: The CT2944-50 packaging is unspecified in available documentation. The CT2944C-50 is supplied in bulk packaging. Packaging format should be confirmed with the supplier based on procurement requirements.
Q: Do both parts meet current compliance standards?
A: Yes. Both CT2944-50 and CT2944C-50 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.
Q: Why is the CT2944-50 classified as obsolete?
A: Obsolete status indicates the part is no longer in active production. The CT2944C-50 represents the current production alternative from the same manufacturer with equivalent specifications.
