HARTING 09653666812 D-Sub Plug Connector - Equivalent & Substitute Parts

Part Overview

The HARTING 09653666812 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 is rated for 6.5A continuous current with an operating temperature range of -55°C to 125°C. The connector 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 original specification, enabling component interchangeability in applications where the primary part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HARTING 09653666812 is determined by strict alignment of the following critical parameters:

• Connector Configuration: 25-position D-Sub plug with male pins
• Shell Size and Layout: Size 3 (DB, B) designation
• Mounting Orientation: Right-angle through-hole configuration
• Termination Type: Solder connection method
• Operating Temperature: -55°C to 125°C range compatibility
• Contact Material and Finish: Gold-plated contacts for signal integrity

The identified substitute part TE Connectivity 1218440-3 maintains equivalence across these core parameters. Variations in current rating, backset spacing, flange design, and compliance certifications are documented in the parameter comparison table below and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1218440-3 serves as a functional equivalent for the HARTING 09653666812 based on matching connector configuration, shell size, mounting type, and operating temperature specifications. Both connectors are active production parts with established supply chains.

Key differentiation factors for selection:

HARTING 09653666812 is the preferred choice for applications requiring ROHS3 compliance and REACH unaffected status. The higher current rating of 6.5A accommodates higher-load signal applications. The larger backset spacing of 0.409" (10.40mm) provides increased board clearance for adjacent components.

TE Connectivity 1218440-3 is suitable for applications where RoHS non-compliance is acceptable and REACH-affected materials are permissible. The military-grade MIL-DTL-24308 specification and AMPLIMITE 109 series designation indicate suitability for aerospace, defense, and marine environments. The lower current rating of 5A is adequate for standard signal-level applications. The reduced backset spacing of 0.318" (8.08mm) enables compact PCB layouts.

Selection between these parts depends on regulatory compliance requirements, current capacity needs, and available board space rather than functional connector performance.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 1218440-3 be used as a direct replacement for HARTING 09653666812?

A: Both connectors share identical 25-position D-Sub plug configuration, Size 3 shell layout, right-angle through-hole mounting, and solder termination. Functional substitution is possible. However, the different backset spacing (0.409" versus 0.318") and current ratings (6.5A versus 5A) must be evaluated against specific application requirements. RoHS and REACH compliance differences must be verified against product regulations.

Q: What is the significance of backset spacing difference?

A: Backset spacing defines the distance from the connector mounting face to the rear of the connector body. The HARTING part at 0.409" (10.40mm) requires more board depth than the TE Connectivity part at 0.318" (8.08mm). PCB layout compatibility must be confirmed before substitution, particularly in space-constrained designs.

Q: Are the contact materials interchangeable?

A: Both connectors feature gold-plated contacts for signal integrity. The HARTING uses copper alloy base material while TE Connectivity uses brass. Both materials are standard for D-Sub connectors and provide equivalent electrical performance for signal-level applications.

Q: What compliance considerations apply to substitution?

A: The HARTING 09653666812 is ROHS3 compliant and REACH unaffected, making it suitable for consumer and commercial applications with environmental restrictions. The TE Connectivity 1218440-3 is RoHS non-compliant and REACH affected, limiting its use to applications where these restrictions do not apply. Regulatory requirements must be confirmed before substitution.

Q: How do current ratings affect substitution?

A: The HARTING part is rated for 6.5A while the TE Connectivity part is rated for 5A. If the application requires current levels between 5A and 6.5A, the TE Connectivity part cannot be substituted. Applications operating below 5A can use either connector without current-related limitations.
