Substitute Part Grouping Explanation

Substitute parts for the M24308/24-55Z are identified within the ITT Cannon 24308-Style D-Sub connector family based on compatibility across the following critical parameters:

Substitution Criteria:

• Connector style: D-Sub plug with male pins
• Termination method: Solder
• Mounting configuration: Panel mount, through-hole, right-angle
• Contact finish: Gold plating
• Shell material and finish: Steel with yellow chromate plated zinc
• Current rating: 7.5A
• Operating temperature range: -55°C to 150°C
• Series family: 24308-Style, D*MM

Variable Parameters (Position-Specific):

• Number of positions (50 vs. 9)
• Shell size and connector layout (DD/D vs. DE/E)
• Number of rows (3 vs. 2)

The M24308/24-31Z qualifies as a substitute where application requirements specify a 9-position connector with shell size 1 (DE, E) configuration, maintaining all core electrical and mechanical compatibility parameters while reducing position count and physical footprint.

Parameter Comparison

Engineering Selection Recommendations

Both the M24308/24-55Z and M24308/24-31Z maintain active product status with confirmed inventory availability. Selection between these parts is determined by application-specific connector position requirements and physical space constraints.

The M24308/24-55Z is specified for applications requiring 50-position signal distribution with shell size 5 (DD, D) configuration. The M24308/24-31Z serves applications requiring 9-position connectivity with shell size 1 (DE, E) configuration. Both parts share identical electrical ratings (7.5A), thermal operating range (-55°C to 150°C), contact metallurgy (gold plating at 50.0µin), and termination method (solder).

Both parts carry RoHS non-compliant status and are classified under ECCN EAR99 with matching HTSUS code 8536.69.4040. Selection should be based on the specific number of signal lines required by the application and the corresponding connector shell size that accommodates the intended circuit board layout and panel cutout dimensions.

Frequently Asked Questions (FAQ)

Q: Can the M24308/24-31Z directly replace the M24308/24-55Z in an existing assembly?

A: Direct mechanical and electrical replacement is not possible due to differences in position count (9 vs. 50), shell size (1 vs. 5), and row configuration (2 vs. 3). The M24308/24-31Z is suitable only for applications designed to operate with 9 signal connections and the corresponding DE/E shell size footprint.

Q: Are the electrical ratings identical between these two connectors?

A: Yes. Both connectors are rated for 7.5A continuous current, operate across -55°C to 150°C, feature gold-plated contacts at 50.0µin thickness, and utilize identical steel shell material with yellow chromate plated zinc finish.

Q: What determines whether a substitute part is acceptable for my application?

A: Substitution is valid only when the application requirements match the position count, shell size, and row configuration of the substitute part. The M24308/24-31Z is appropriate for 9-position applications with shell size 1 (DE, E) layout. All other electrical and mechanical parameters remain equivalent to the M24308/24-55Z.

Q: Are there any compliance or certification differences between these parts?

A: Both parts carry identical RoHS non-compliant status and are classified under the same ECCN (EAR99) and HTSUS (8536.69.4040) codes. No compliance differentiation exists between the two connectors.

Q: What is the significance of the shell size designation?

A: Shell size determines the physical dimensions of the connector housing and the arrangement of contact positions. Shell size 5 (DD, D) accommodates 50 positions in a 3-row configuration, while shell size 1 (DE, E) accommodates 9 positions in a 2-row configuration. Shell size selection is driven by application circuit requirements and available panel space.
