Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DDMM-50P-Z are identified based on strict electrical and mechanical parameter alignment. The following criteria establish substitution validity:

Primary Compatibility Parameters:

• Connector style: D-Sub (required match)
• Connector type: Plug, Male Pins (required match)
• Number of positions: 50 (required match)
• Number of rows: 3 (required match)
• Shell size, connector layout: 5 (DD, D) (required match)
• Termination method: Solder (required match)
• Shell material and finish: Steel, Tin Plated (required match)
• Contact finish: Gold (required match)
• Current rating: 7.5A (required match)
• Material flammability rating: UL94 V-0 (required match)
• Contact material: Copper Alloy (required match)

Allowable Variations in Substitution:

• Mounting type: Panel mount (main part) versus through-hole board mount (substitute parts) represent different mechanical installation methods but maintain electrical equivalence
• Contact finish thickness: Variations in gold plating thickness (50.0µin, 8.00µin, or flash) are acceptable within industry standards for signal-level applications
• Dielectric material: PCT (main part) versus PBT glass-filled (substitute parts) both meet UL94 V-0 flammability requirements
• Operating temperature upper limit: 150°C (main part) versus 125°C (substitute parts) represents a functional difference; substitutes are suitable for applications within -55°C to 125°C range
• Ingress protection rating: Substitute parts feature IP20 rating; main part does not specify ingress protection
• Voltage rating: Substitute parts specify 125V; main part does not specify voltage rating
• RoHS compliance: Main part is RoHS non-compliant; substitute parts are ROHS3 compliant

The two identified substitute parts (163A16199X and 163A16299X) differ only in flange feature design: 163A16199X features board-side 4-40 mounting, while 163A16299X features mating-side 4-40 mounting. Both maintain full electrical and mechanical compatibility with the DDMM-50P-Z within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

DDMM-50P-Z (Primary Part): The DDMM-50P-Z remains the primary selection when panel mount installation with unthreaded housing is required. This part is active and maintains adequate inventory levels. The extended operating temperature range of -55°C to 150°C provides thermal capability for high-temperature applications. RoHS non-compliance status must be evaluated against project regulatory requirements.

163A16199X (Substitute - Board-Side Flange): The 163A16199X is suitable for applications requiring board-side mounting with 4-40 threaded flange attachment. This part is active with higher inventory availability (1083 units). ROHS3 compliance status supports regulatory requirements in restricted substance applications. The operating temperature range of -55°C to 125°C is appropriate for standard industrial and commercial applications. IP20 ingress protection rating provides enhanced environmental sealing compared to the main part specification.

163A16299X (Substitute - Mating-Side Flange): The 163A16299X is suitable for applications requiring mating-side mounting with 4-40 threaded flange attachment. This part is active with equivalent high inventory availability (1085 units). ROHS3 compliance and IP20 ingress protection rating match the 163A16199X specifications. Selection between 163A16199X and 163A16299X depends solely on mechanical mounting orientation requirements: board-side versus mating-side flange positioning.

Selection Criteria:

• Applications requiring panel mount installation: DDMM-50P-Z
• Applications requiring board-side threaded mounting: 163A16199X
• Applications requiring mating-side threaded mounting: 163A16299X
• Applications with temperature requirements exceeding 125°C: DDMM-50P-Z only
• Applications requiring RoHS3 compliance: 163A16199X or 163A16299X
• Applications requiring enhanced ingress protection: 163A16199X or 163A16299X

Frequently Asked Questions (FAQ)

Q: Can the 163A16199X or 163A16299X be used as direct replacements for the DDMM-50P-Z in existing designs?

A: Electrical substitution is valid based on matching connector style, pin count, row configuration, shell size, termination method, current rating, and flammability rating. Mechanical substitution requires design review of mounting interface. The DDMM-50P-Z uses panel mount with unthreaded housing, while substitute parts use through-hole board mount with 4-40 threaded flanges. PCB layout and mechanical mounting structure must accommodate the different flange designs.

Q: What is the difference between 163A16199X and 163A16299X?

A: Both parts are electrically and mechanically identical except for flange positioning. The 163A16199X features a board-side 4-40 flange, positioning the threaded attachment points on the PCB side of the connector. The 163A16299X features a mating-side 4-40 flange, positioning the threaded attachment points on the mating connector side. Selection depends on mechanical assembly requirements and available mounting space.

Q: Are there temperature limitations when substituting the DDMM-50P-Z with 163A16199X or 163A16299X?

A: Yes. The DDMM-50P-Z operates from -55°C to 150°C, while both Amphenol CONEC substitutes operate from -55°C to 125°C. Applications requiring sustained operation above 125°C must use the DDMM-50P-Z. Applications within the -55°C to 125°C range can use either part.

Q: What is the significance of the different contact finish thicknesses?

A: The DDMM-50P-Z specifies 50.0µin (1.27µm) gold plating, while 163A16199X specifies 8.00µin (0.203µm) and 163A16299X specifies flash plating. All three finishes meet signal-level connector requirements. Thicker plating provides enhanced durability in high-cycle mating applications; thinner plating is suitable for fixed installations with minimal connector cycling.

Q: Does RoHS compliance status affect substitution decisions?

A: RoHS compliance is a regulatory and procurement consideration, not an electrical or mechanical compatibility factor. The DDMM-50P-Z is RoHS non-compliant, while both Amphenol CONEC substitutes are ROHS3 compliant. Projects with restricted substance requirements must select 163A16199X or 163A16299X. Projects without such requirements can use any part based on other technical criteria.

Q: What does the IP20 ingress protection rating on the substitute parts indicate?

A: IP20 rating indicates protection against solid objects larger than 12mm and no protection against liquid ingress. The DDMM-50P-Z does not specify an ingress protection rating. The IP20 rating on substitute parts provides documented environmental sealing performance for applications requiring enhanced protection against dust and debris ingress.

Q: Can the DDMM-50P-Z be used in applications designed for the 163A16199X or 163A16299X?

A: Electrical compatibility is confirmed. Mechanical compatibility requires design review. The DDMM-50P-Z panel mount unthreaded housing differs from the board-side or mating-side 4-40 threaded flanges on substitute parts. Existing mechanical mounting structures designed for threaded flanges cannot directly accommodate the DDMM-50P-Z without modification.

Q: Are all three parts suitable for signal-level applications?

A: Yes. All three parts are classified as signal contact type connectors with 7.5A current rating and copper alloy contact material. All three meet UL94 V-0 flammability requirements. Electrical performance is equivalent across all three parts within their respective operating temperature ranges.
