Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for D-Sub receptacle connectors is determined by strict alignment of the following core parameters:

Mandatory Matching Parameters:

• Connector style (D-Sub)
• Connector type (Receptacle, Female Sockets)
• Number of positions (9)
• Number of rows (2)
• Shell size and connector layout (1 / DE, E)
• Termination method (Solder)
• Contact type (Signal)
• Contact finish (Gold)
• Material flammability rating (UL94 V-0)
• Moisture sensitivity level (MSL 1)

Allowable Variation Parameters:

• Current rating (minimum 6A required)
• Voltage rating (when specified)
• Operating temperature range (when specified)
• Shell material and finish composition
• Contact material composition
• Mounting type configuration
• RoHS compliance status
• Dielectric material composition

The ITT Cannon DEMV9SNA197 meets all mandatory matching parameters and demonstrates compatibility within allowable variation ranges.

Engineering Selection Recommendations

TE Connectivity 205734-1 Selection Criteria:

• Active product status with established supply chain
• RoHS non-compliant designation for legacy system applications
• Yellow chromate plated zinc shell finish for corrosion resistance in specific environmental conditions
• Phosphor bronze contact material composition
• Operating temperature range of -55°C to 105°C
• 6A current rating specification

ITT Cannon DEMV9SNA197 Selection Criteria:

• Active product status with established supply chain
• RoHS compliant designation for new design and regulatory requirement applications
• Tin-nickel plated shell finish for alternative corrosion resistance profile
• Copper alloy contact material composition
• Extended operating temperature range of -55°C to 125°C
• Higher current rating of 7.5A
• Panel mount configuration option in addition to through-hole mounting

Selection between these parts is determined by compliance requirements, environmental specifications, and mounting configuration needs. Both parts maintain equivalent electrical and mechanical functionality within their respective parameter specifications.

Frequently Asked Questions (FAQ)

Q: Can the ITT Cannon DEMV9SNA197 directly replace the TE Connectivity 205734-1 in existing designs?

A: Direct replacement is possible when the design accommodates the parameter variations. The ITT Cannon part maintains all mandatory matching parameters including connector style, position count, shell size, termination method, and contact finish. Verify that the extended operating temperature range (-55°C to 125°C), higher current rating (7.5A), and RoHS compliant status align with application requirements. The panel mount configuration option does not preclude through-hole mounting compatibility.

Q: What are the differences in shell material finish between these connectors?

A: The TE Connectivity 205734-1 features a yellow chromate plated zinc finish, while the ITT Cannon DEMV9SNA197 uses a tin-nickel plated finish. Both finishes provide corrosion resistance; selection depends on specific environmental exposure conditions and compatibility with existing system materials.

Q: Does the RoHS compliance difference affect substitution eligibility?

A: RoHS compliance status is a variation parameter that does not prevent substitution. The TE Connectivity part is RoHS non-compliant, suitable for legacy systems. The ITT Cannon part is RoHS compliant, suitable for applications requiring regulatory compliance. Selection is based on system requirements and regulatory environment.

Q: Are the contact materials interchangeable?

A: Both contact materials (phosphor bronze in the TE Connectivity part and copper alloy in the ITT Cannon part) are acceptable for signal-level D-Sub applications. Contact material composition is a variation parameter. Both maintain gold finish and equivalent electrical performance within specified current and voltage ratings.

Q: What is the significance of the extended operating temperature range in the ITT Cannon part?

A: The ITT Cannon DEMV9SNA197 operates from -55°C to 125°C, compared to -55°C to 105°C for the TE Connectivity part. This extended upper temperature limit provides additional thermal margin for applications operating in elevated temperature environments. This is a compatible variation that does not restrict substitution.

Q: How do the current ratings affect part selection?

A: The TE Connectivity 205734-1 is rated for 6A, while the ITT Cannon DEMV9SNA197 is rated for 7.5A. The higher rating in the ITT Cannon part is compatible with applications requiring the 6A specification. Current rating is an allowable variation parameter where higher ratings are acceptable for equivalent or lower current applications.

Q: Are there packaging or inventory considerations for these parts?

A: Both parts are supplied in bulk packaging. TE Connectivity 205734-1 has 1088 pieces in stock, while ITT Cannon DEMV9SNA197 has 874 pieces in stock. Inventory levels are subject to change and should be verified at time of procurement.
