HARTING 09654637811 D-Sub Plug 37-Position Right Angle Solder Connector

Part Overview

The HARTING 09654637811 is a 37-position D-Sub plug connector with right-angle through-hole solder termination. This connector is designed for applications requiring robust signal transmission in industrial and aerospace environments. The part is currently active in production with 956 units in stock. Alternative components may be required due to supply constraints, design revisions, or specific compliance requirements in target applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HARTING 09654637811 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector type: D-Sub plug with male pins
• Position count: 37 positions
• Row configuration: 2 rows
• Shell size: 4 (DC, C)
• Mounting orientation: Right angle through-hole
• Termination: Solder

Secondary Compatibility Parameters:

• Operating temperature range: -55°C to 125°C minimum
• Current rating: Minimum 5A (substitute may have lower rating if application permits)
• Backset spacing tolerance: Acceptable variance within mechanical fit constraints

The TE Connectivity part 1218440-4 meets all primary compatibility criteria and operates within the same temperature range. Differences in contact finish, shell material finish, and RoHS compliance status do not affect functional interchangeability for signal transmission applications.

Parameter Comparison

Engineering Selection Recommendations

HARTING 09654637811 Selection Criteria:

• Applications requiring ROHS3 compliance
• Designs with current requirements up to 6.5A
• Standard industrial applications without military specification requirements
• Active production status ensures supply continuity

TE Connectivity 1218440-4 Selection Criteria:

• Military or aerospace applications requiring MIL-DTL-24308 compliance
• Designs where cadmium-plated steel shell provides enhanced environmental protection
• Applications with current requirements up to 5A
• Designs where gold-plated contacts are specified
• Applications where RoHS non-compliance is acceptable

Both connectors are active products with confirmed inventory availability. Selection between these parts depends on compliance mandates and environmental protection requirements specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1218440-4 directly replace the HARTING 09654637811 in existing designs?

A: Direct mechanical and electrical replacement is possible if the application current requirement does not exceed 5A and RoHS non-compliance is acceptable. The identical shell size, position count, and mounting configuration ensure physical interchangeability. PCB layout and connector orientation remain unchanged.

Q: What is the significance of the current rating difference (6.5A vs. 5A)?

A: The HARTING part supports higher continuous current. If your application draws more than 5A, the TE Connectivity substitute is not suitable. If your application operates at 5A or below, both parts are functionally equivalent for current handling.

Q: Does the gold contact finish on the TE part provide performance advantages?

A: Gold plating improves contact resistance stability and corrosion resistance over extended service life. For signal-only applications in controlled environments, the contact finish difference has minimal impact. For high-reliability or harsh environment applications, the gold-plated TE part may provide extended service life.

Q: Why does the HARTING part specify ROHS3 compliance while the TE part does not?

A: Compliance status reflects manufacturing process and material sourcing at the time of production. ROHS3 compliance is mandatory for products sold into European markets and many regulated industries. If your application requires ROHS3 certification, the HARTING part is the correct selection.

Q: Are there any mechanical differences that affect PCB mounting?

A: Both parts use identical through-hole right-angle mounting. Backset spacing differs slightly (10.40mm vs. 8.08mm), but this does not affect standard D-Sub connector mounting practices. Verify your PCB footprint accommodates the specific backset dimension of your selected part.

Q: What is the inventory status for both parts?

A: HARTING 09654637811 has 956 units in stock. TE Connectivity 1218440-4 has 1080 units in stock. Both parts are available for immediate procurement.
