Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ITT Cannon 192993-0021 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Receptacle Housing for female sockets
• Number of Positions: 4
• Mounting Type: Panel Mount with flange feature
• Shell Material: Zinc Alloy with nickel finish
• Shielding: Shielded configuration
• Material Flammability: UL94 V-0 rating
• Moisture Sensitivity: MSL 1 (Unlimited)

Allowable Variations:

• Shell Size - Insert: Equivalent sizes within circular connector standards (10-0004 to 10-4 conversion acceptable)
• Fastening Type: Detent Lock or Bayonet Lock (both provide secure mating)
• Orientation: Keyed or Normal (both provide polarization control)
• Contact Type: Crimp, Solder, Solder Cup, or Crimp alone (all support electrical continuity)
• Operating Temperature: Minimum -40°C acceptable (substitute range -40°C ~ 105°C vs. -55°C ~ 105°C)
• Ingress Protection: IP67 rating acceptable as enhancement over unspecified rating

The Amphenol Sine Systems RT00104SNH qualifies as a direct substitute based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (ITT Cannon 192993-0021):

• Active product status with established supply chain
• RoHS Compliant certification
• Extended operating temperature range (-55°C minimum)
• Keyed orientation for enhanced polarization control
• Detent lock fastening mechanism

Substitute Part (Amphenol Sine Systems RT00104SNH):

• Active product status with confirmed availability (1330 pcs in stock)
• ROHS3 Compliant certification (meets current regulatory requirements)
• IP67 ingress protection rating (enhanced environmental sealing)
• Bayonet lock fastening (alternative secure mating method)
• Normal orientation (standard polarization approach)
• Minimum operating temperature of -40°C (acceptable for most industrial applications)

Selection between these parts should be based on application-specific requirements regarding minimum operating temperature, fastening mechanism preference, and ingress protection needs. Both parts satisfy the core functional and compliance requirements for 4-position shielded circular connector receptacle housings with panel mount configuration.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol RT00104SNH directly replace the ITT Cannon 192993-0021 in all applications?

A: The Amphenol part qualifies as a substitute for applications where the operating temperature does not fall below -40°C. If your application requires operation at temperatures between -55°C and -40°C, the ITT Cannon part is required. Both parts are mechanically and electrically compatible for 4-position shielded circular connector receptacle housing functions.

Q: What is the difference between Detent Lock and Bayonet Lock fastening?

A: Both fastening types provide secure mating connections. Detent lock uses a spring-loaded mechanism for engagement, while bayonet lock uses a twist-and-lock mechanism. Selection depends on application requirements for mating frequency and user interface preference.

Q: Are the shell sizes 10-0004 and 10-4 interchangeable?

A: Yes. These designations refer to equivalent shell sizes within circular connector standards. Both accommodate 4-position configurations with identical contact spacing and mechanical interfaces.

Q: Does the difference in insert material (Polyamide vs. Thermoplastic) affect performance?

A: Both materials meet UL94 V-0 flammability requirements and provide equivalent electrical insulation properties. The thermoplastic insert in the Amphenol part offers comparable performance for the specified operating temperature and environmental conditions.

Q: What does the IP67 rating on the Amphenol part provide?

A: IP67 certification indicates dust-tight and waterproof performance. This represents an enhancement over the unspecified ingress protection of the ITT Cannon part and is beneficial for applications requiring environmental sealing.

Q: Are both parts RoHS compliant?

A: Yes. The ITT Cannon part carries RoHS Compliant status, and the Amphenol part carries ROHS3 Compliant status. Both meet current regulatory requirements for restricted substances.
