HARTING 09651237802 D-Sub Plug Connector - Equivalent & Substitute Parts

Part Overview

The HARTING 09651237802 is a 9-position D-Sub plug connector with right-angle solder termination, designed for through-hole mounting applications. This connector features male pins, a DE/E shell size (Size 1), and is rated for 6.5A continuous current operation across an extended temperature range of -55°C to 125°C. The part is currently active in production and maintains ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical parameters align with the core connector specifications, enabling direct functional replacement in applications where the original part becomes unavailable or when alternative certifications are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HARTING 09651237802 is determined by strict alignment of the following core parameters:

• Connector Configuration: 9-position D-Sub plug with male pins
• Shell Size: Size 1 (DE, E) layout
• Mounting Orientation: Right-angle through-hole installation
• Termination Type: Solder connection
• Electrical Rating: Current capacity and temperature range compatibility
• Physical Dimensions: Backset spacing and connector geometry

The TE Connectivity Aerospace, Defense and Marine part number 1218440-1 qualifies as a substitute based on matching connector type, position count, shell size, mounting style, and termination method. Both parts operate across the identical temperature range (-55°C to 125°C) and maintain MSL 1 rating. Differences in current rating (5A vs. 6.5A), backset spacing (0.318" vs. 0.409"), contact finish, and compliance certifications are noted for engineering evaluation but do not preclude functional substitution in applications where the substitute's electrical specifications are adequate.

Parameter Comparison

Engineering Selection Recommendations

HARTING 09651237802 is the primary selection for applications requiring ROHS3 compliance and REACH unaffected status. The higher current rating (6.5A) accommodates applications with greater power delivery requirements. Active production status ensures long-term availability and supply chain stability.

TE Connectivity 1218440-1 serves as a functional substitute in applications where the 5A current rating is adequate and military-grade specifications (MIL-DTL-24308, AMPLIMITE 109 series) are beneficial. The gold-plated contact finish provides enhanced corrosion resistance in harsh environments. This part is suitable for aerospace, defense, and marine applications where military qualification is required. Note that RoHS non-compliance and REACH affected status require verification against end-product regulatory requirements before selection.

Selection between these parts must account for current load requirements, regulatory compliance mandates, environmental exposure conditions, and supply availability at the time of procurement.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1218440-1 directly replace the HARTING 09651237802 in all applications?

A: Direct replacement is possible only when the application's current requirement does not exceed 5A and regulatory compliance with RoHS3 and REACH unaffected status is not mandated. The identical connector configuration, shell size, mounting style, and temperature range support functional interchangeability in compatible applications.

Q: What is the significance of the backset spacing difference (0.409" vs. 0.318")?

A: Backset spacing defines the distance from the connector's rear face to the contact insertion point. The 0.409" spacing on the HARTING part differs from the 0.318" spacing on the TE Connectivity part. This difference may affect PCB layout, mating connector positioning, and cable routing. Verify mechanical compatibility with mating connectors and enclosure constraints before substitution.

Q: Why does the TE Connectivity part have a lower current rating?

A: The 5A rating on the TE Connectivity 1218440-1 reflects its design specifications and military qualification parameters. The HARTING 09651237802 is rated for 6.5A. Applications requiring sustained currents above 5A must use the HARTING part or verify that the TE Connectivity part's thermal and electrical performance is acceptable for the specific duty cycle.

Q: Are there compliance implications when substituting between these parts?

A: Yes. The HARTING part is ROHS3 compliant and REACH unaffected, while the TE Connectivity part is RoHS non-compliant and REACH affected. Products destined for European markets or subject to RoHS/REACH regulations must retain the HARTING part unless alternative compliance documentation is provided. Verify end-product regulatory requirements before substitution.

Q: What is the difference between copper alloy and brass contact materials?

A: Both materials provide electrical conductivity suitable for signal transmission in D-Sub connectors. Copper alloy offers general-purpose performance, while brass provides additional corrosion resistance and is commonly used in military and marine applications. The gold plating on the TE Connectivity part's brass contacts further enhances corrosion resistance compared to unplated copper alloy contacts.

Q: Can these connectors be used interchangeably with other D-Sub sizes?

A: No. Both parts are Size 1 (DE, E) connectors with 9 positions. They are not compatible with Size 2 (DB), Size 3 (DC), or other D-Sub sizes. Connector size and position count must match exactly for proper mating and electrical function.
