HARTING 09653666811 D-Sub Plug Connector - Equivalent & Substitute Parts

Part Overview

The HARTING 09653666811 is a 25-position D-Sub plug connector with right-angle solder termination, designed for through-hole PCB mounting. This connector features male pins, a DB/B shell size (Size 3), and gold-plated contacts rated for 6.5A continuous current. The part is currently active in production with 902 units in stock inventory.

D-Sub connectors of this specification are essential in applications requiring reliable signal transmission across multiple channels with standardized mechanical and electrical interfaces. Equivalent substitute parts may be required due to supply chain constraints, inventory availability, or specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HARTING 09653666811 is determined by the following critical parameters:

• Connector Configuration: Plug type with male pins, 25-position, 2-row arrangement
• Shell Specification: DB/B Size 3 mechanical interface
• Mounting Orientation: Right-angle through-hole solder termination
• Electrical Performance: Contact finish (gold), current rating capability, and operating temperature range
• Mechanical Compatibility: Backset spacing and flange feature compatibility

The TE Connectivity Aerospace, Defense and Marine part number 1218440-3 qualifies as a functional equivalent based on matching connector type, position count, shell size, mounting method, and operating temperature range. Both parts maintain the same mechanical footprint for D-Sub Size 3 connectors and support solder termination on through-hole PCBs.

Engineering Selection Recommendations

Primary Selection: HARTING 09653666811

The HARTING 09653666811 is the preferred choice for new designs and applications requiring RoHS3 compliance and REACH unaffected status. This part maintains active production status with adequate inventory availability (902 units in stock).

Substitute Selection: TE Connectivity 1218440-3

The TE Connectivity 1218440-3 serves as a functional equivalent for applications where RoHS compliance is not a requirement. This part is qualified to MIL-DTL-24308 military specifications and carries the AMPLIMITE 109 series designation, making it suitable for aerospace, defense, and marine applications. The part is also actively produced with higher inventory availability (1242 units in stock).

Key Consideration: The TE Connectivity substitute has a lower current rating (5A versus 6.5A). Applications requiring the full 6.5A current capacity must use the HARTING part or verify that the 5A rating is sufficient for the intended circuit.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1218440-3 be used as a direct replacement for the HARTING 09653666811?

A: Yes, for applications where the 5A current rating is adequate. Both connectors share identical mechanical interfaces (D-Sub Size 3, 25-position, right-angle solder mount) and operate across the same temperature range (-55°C to 125°C). However, applications requiring 6.5A continuous current must use the HARTING part.

Q: What are the compliance differences between these two parts?

A: The HARTING 09653666811 is RoHS3 compliant and REACH unaffected. The TE Connectivity 1218440-3 is RoHS non-compliant and REACH affected. Applications subject to RoHS or REACH regulations must use the HARTING part.

Q: Are the backset spacings compatible?

A: The HARTING part specifies 0.409" (10.40mm) backset spacing, while the TE Connectivity part specifies 0.318" (8.08mm). This difference may affect PCB layout and mechanical fit. Verify backset spacing compatibility with your specific PCB design before substitution.

Q: What is the difference in shell material finish?

A: The HARTING part uses steel with unspecified finish, while the TE Connectivity part uses steel with cadmium plating. Both provide corrosion resistance suitable for standard industrial environments. The cadmium plating on the TE Connectivity part offers enhanced protection in harsh environments.

Q: Which part should be selected for new product designs?

A: For new designs without specific military or aerospace requirements, the HARTING 09653666811 is recommended due to its RoHS3 compliance, higher current rating, and REACH unaffected status. The TE Connectivity 1218440-3 is appropriate for military, aerospace, and defense applications where MIL-DTL-24308 qualification is required.
