Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for D-Sub connectors is determined by the following critical parameters:

• Connector Configuration: Plug type with male pins, 25-position, DB/B shell size (Size 3)
• Mounting Geometry: Through-hole, right-angle orientation
• Termination Method: Solder connection to PCB
• Electrical Performance: Current rating and contact material compatibility
• Environmental Compliance: Operating temperature range and regulatory certifications

The substitute part TE Connectivity 1218440-3 shares the core mechanical and electrical characteristics required for functional equivalence: identical position count, shell size, mounting type, termination method, and operating temperature range. Both parts accommodate 25-position signal distribution in D-Sub format with solder termination and right-angle PCB mounting.

Parameter Comparison

Engineering Selection Recommendations

HARTING 09653666816 is the primary selection for applications requiring ROHS3 compliance and maximum current capacity (6.5A). This part is actively manufactured and maintains full regulatory compliance for modern industrial and commercial applications.

TE Connectivity 1218440-3 serves as a functional substitute where legacy military specifications (MIL-DTL-24308, AMPLIMITE 109 series) are specified or where cadmium-plated steel shells are required for corrosion resistance in specific environments. This part is suitable for applications with current requirements at or below 5A. The RoHS non-compliant status requires verification against project regulatory requirements before selection.

Both parts share identical mechanical interfaces, pin configurations, and thermal operating ranges, enabling direct PCB layout compatibility. Selection between these parts depends on compliance mandates, current load specifications, and environmental protection requirements rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 1218440-3 be used as a direct replacement for HARTING 09653666816 in all applications?

A: Direct substitution is mechanically and thermally compatible. However, verify two conditions: (1) application current does not exceed 5A (TE part rating), and (2) RoHS compliance is not a project requirement. The TE part is RoHS non-compliant, which may disqualify it for certain regulatory environments.

Q: What is the difference in current rating between these parts?

A: HARTING 09653666816 is rated for 6.5A continuous current, while TE Connectivity 1218440-3 is rated for 5A. Applications requiring current above 5A must use the HARTING part or select an alternative connector rated for higher current.

Q: Are the physical dimensions and PCB footprints identical?

A: Both parts use identical shell size (DB/B, Size 3), right-angle through-hole mounting, and 25-position configuration. PCB footprints are compatible. Note: backset spacing differs slightly (HARTING 0.409", TE 0.318"), which may affect connector body clearance on the PCB; verify mechanical fit in your specific layout.

Q: Which part should be selected for new designs?

A: For new designs, HARTING 09653666816 is recommended due to ROHS3 compliance and higher current rating, ensuring compatibility with modern regulatory requirements and providing design margin for current capacity.

Q: Is the TE part suitable for military or aerospace applications?

A: TE Connectivity 1218440-3 is qualified to MIL-DTL-24308 and carries the AMPLIMITE 109 military series designation, making it appropriate for military and defense applications where this specification is required. HARTING 09653666816 does not carry military qualification.
