HARTING 09653666813 D-Sub 25 Position Right Angle Solder Plug Connector

Part Overview

The HARTING 09653666813 is a 25 position D-Sub plug connector with right angle through-hole solder termination. This connector features a DB/B shell size (Size 3) with male pins, mating side female screwlock (4-40) flange, and board lock functionality. The part is actively manufactured and widely used in industrial and commercial applications requiring robust D-Sub interconnection solutions.

Equivalent and substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits selection from qualified alternatives that meet identical or compatible electrical and mechanical specifications.

Engineering Selection Recommendations

Preferred Substitutes (Full Compliance):

The Amphenol ICC (FCI) D25P13A4GV00LF is the primary recommended substitute. This part maintains identical mechanical and electrical specifications to the HARTING 09653666813, including matching backset spacing (0.409"), identical flange configuration (mating side female screwlock 4-40), board lock features, and full operating temperature range (-55°C ~ 125°C). Both parts are ROHS3 compliant and REACH unaffected, ensuring regulatory alignment. The D25P13A4GV00LF is available in higher inventory (1932 pcs) and belongs to the Delta D series, a widely qualified platform in industrial applications.

The Amphenol ICC (FCI) D25P13A4GL00LF is an alternative substitute with identical electrical and mechanical compatibility. The primary distinction is the flange configuration (housing/shell M3 mounting versus mating side screwlock). This part offers higher inventory availability (1239 pcs) and maintains full compliance across all critical parameters including temperature range and RoHS3 status.

Secondary Substitutes (Conditional Use):

The TE Connectivity AMPLIMITE HDP-20 series part 5745436-3 is functionally compatible with the following considerations: the backset spacing differs (0.454" versus 0.409"), and the maximum operating temperature is limited to 105°C versus the required 125°C. This part is suitable only for applications where the reduced temperature range and spacing tolerance are acceptable. Current rating is 6A, which meets the 6.5A requirement with minimal margin.

The Amphenol ICC (FCI) DBM25P500 offers the highest current rating (7.5A per contact) and maintains full temperature range compatibility (-55°C ~ 125°C). However, this part is RoHS non-compliant, restricting its use to applications where RoHS exemptions are permitted or not required. The unthreaded housing/shell flange configuration differs from the original specification.

Not Recommended:

The Amphenol ICC (FCI) D25P13A4GX00LF is not recommended as a primary substitute due to REACH Affected status, which introduces regulatory complexity and potential supply chain restrictions compared to REACH Unaffected alternatives.

Frequently Asked Questions (FAQ)

Q: Can I use the TE Connectivity 5745436-3 as a direct replacement for the HARTING 09653666813?

A: The TE Connectivity part is mechanically and electrically compatible for most applications. However, the backset spacing differs by 0.045" (1.13mm), and the maximum operating temperature is limited to 105°C. Verify that your application does not require operation above 105°C and that the spacing tolerance is acceptable for your PCB layout before substitution.

Q: What is the difference between the three Amphenol D25P13 variants (GL, GV, GX)?

A: All three variants (D25P13A4GL00LF, D25P13A4GV00LF, D25P13A4GX00LF) share identical electrical specifications and operating temperature range. The primary differences are flange configurations: GL features housing/shell M3 mounting, GV features mating side female screwlock (4-40), and GX features housing/shell 4-40 mounting. Select based on your mechanical mounting requirements. The GV variant most closely matches the original HARTING flange specification.

Q: Is the Amphenol DBM25P500 suitable for my application?

A: The DBM25P500 is electrically and thermally compatible with the HARTING 09653666813 and offers superior current handling (7.5A per contact). However, this part is RoHS non-compliant. Use this part only if your application or regional regulations do not require RoHS compliance. Verify with your procurement and compliance teams before selection.

Q: What does "backset spacing" mean, and why does it matter?

A: Backset spacing is the distance from the rear of the connector shell to the solder pin termination points on the PCB. The HARTING part specifies 0.409" (10.40mm). Substitute parts with different backset spacing may not align properly with existing PCB footprints. The Amphenol D25P13 series maintains identical spacing (0.409"), ensuring direct PCB compatibility. The TE Connectivity part (0.454") requires PCB layout verification before use.

Q: Are all these connectors RoHS compliant?

A: Most substitutes are RoHS compliant or ROHS3 compliant. The exception is the Amphenol DBM25P500, which is RoHS non-compliant. If your application or market requires RoHS compliance, select from the ROHS3 compliant options: Amphenol D25P13A4GV00LF, D25P13A4GX00LF, or TE Connectivity 5745436-3.

Q: What is the difference between REACH Unaffected and REACH Affected status?

A: REACH Unaffected parts contain no substances of very high concern (SVHC) listed under EU REACH regulations and require no special documentation. REACH Affected parts contain listed SVHC substances and may require additional compliance documentation, supplier declarations, and regulatory review. For unrestricted global supply chain use, select REACH Unaffected alternatives.

Q: Can I mix and match these connectors in the same assembly?

A: All listed substitutes are mechanically and electrically compatible within the D-Sub 25 position standard. However, for consistency, reliability, and supply chain management, use a single part number throughout an assembly or product line. If substitution becomes necessary due to supply constraints, document the change and verify compatibility with your system design and testing protocols.
