Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 1218440-5 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Connector style (D-Sub)
• Connector type (Plug, Male Pins)
• Number of positions (50)
• Number of rows (3)
• Shell size and layout (5, DD, D)
• Mounting type (Through Hole, Right Angle)
• Termination method (Solder)
• Shell material and finish (Steel, Cadmium Plated)
• Contact finish and thickness (Gold, 10.0µin)
• Current rating (5A)
• Backset spacing (0.318")
• Operating temperature range (-55°C to 125°C)
• Series compliance (Military, MIL-DTL-24308, AMPLIMITE 109)
• Contact material (Brass)
• Color (Black)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Selection between these parts may be based on inventory availability, lead time, or procurement source requirements. The 1218444-5 currently has 1032 units in stock compared to 739 units for the 1218440-5.

Frequently Asked Questions (FAQ)

Q: Are the 1218440-5 and 1218444-5 fully interchangeable?

A: Yes. Both parts are parametric equivalents meeting identical electrical and mechanical specifications. They share the same connector style, pin configuration, shell size, termination method, material specifications, and operating temperature range. Both comply with MIL-DTL-24308 military specification.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution eligibility is determined by matching the following parameters: connector style (D-Sub), connector type (Plug, Male Pins), number of positions (50), number of rows (3), shell size (5, DD, D), mounting type (Through Hole, Right Angle), termination method (Solder), shell material and finish (Steel, Cadmium Plated), contact finish and thickness (Gold, 10.0µin), current rating (5A), backset spacing (0.318"), operating temperature range (-55°C to 125°C), series compliance (Military, MIL-DTL-24308, AMPLIMITE 109), contact material (Brass), and color (Black).

Q: Do both parts have the same compliance and regulatory status?

A: Yes. Both the 1218440-5 and 1218444-5 share identical compliance designations: RoHS non-compliant, REACH Affected, EAR99 export control classification, and HTSUS code 8536.69.4040. Both parts are active in production status.

Q: What is the difference between these two part numbers?

A: The parts are functionally and mechanically identical. The difference lies in the base product number (1218440 versus 1218444), which may reflect internal TE Connectivity manufacturing or inventory tracking distinctions. Current inventory levels differ, with 1218444-5 having 1032 units available compared to 739 units for 1218440-5.

Q: Can these connectors be used in high-temperature applications?

A: Both connectors are rated for operating temperatures from -55°C to 125°C. Applications requiring operation outside this range require alternative connector specifications.

Q: What is the current-carrying capacity of these connectors?

A: Both connectors are rated for 5A current per position. Circuit design must account for this current limitation when selecting wire gauge and termination specifications.

Q: Are these connectors suitable for aerospace and defense applications?

A: Yes. Both connectors are manufactured by TE Connectivity Aerospace, Defense and Marine and comply with military specification MIL-DTL-24308, making them suitable for aerospace and defense applications within the specified electrical and environmental parameters.
