DEMV09P500 D-Sub Plug Connector - Equivalent & Substitute Parts

Part Overview

The DEMV09P500 is a 9-position D-Sub plug connector manufactured by Amphenol ICC (FCI) in the DM HE501 series. This right-angle, through-hole solder connector features male pins with gold-plated contacts and a mating-side female screwlock. The connector is rated for 7.5A continuous current and operates across -55°C to 125°C. Currently in active production status with 1009 units in stock, this connector serves as a standard interface component in industrial and telecommunications applications. Substitute parts are necessary to address supply chain flexibility, regional availability, manufacturing lead times, and design optimization requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DEMV09P500 is determined by strict alignment of the following critical parameters:

Primary Compatibility Criteria:

• Connector type: D-Sub plug with male pins
• Position count: 9 positions
• Shell size and layout: 1 (DE, E)
• Mounting configuration: Through hole, right angle
• Termination: Solder
• Flange feature: Mating side, female screwlock (4-40)
• Current rating: Minimum 6A (DEMV09P500 rated 7.5A)
• Operating temperature: Minimum -55°C to 125°C range
• Contact type: Signal

Acceptable Variations:

• Shell material finish (steel with different plating options)
• Contact finish (gold or alternative finishes)
• Dielectric material composition (different thermoplastic formulations)
• RoHS compliance status (compliant substitutes acceptable for non-compliant original)
• Backset spacing variations within mechanical tolerance
• Additional features (board lock, grounding indents, mounting brackets) that do not interfere with mating

The six substitute parts listed below meet all primary compatibility criteria and are electrically and mechanically interchangeable with the DEMV09P500 in standard D-Sub applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

The HARTING parts 09661626813, 09661627813, 09661636813, and 09661637813 provide direct mechanical and electrical substitution for the DEMV09P500. All four maintain the mating-side female screwlock flange configuration, support the full -55°C to 125°C operating range, and carry ROHS3 compliance certification. These parts are suitable for applications requiring RoHS-compliant alternatives to the original non-compliant DEMV09P500.

Secondary Substitutes (Conditional Compatibility):

The HARTING part 09661237803 operates across the full -55°C to 125°C temperature range with ROHS3 compliance but features a housing/shell flange configuration rather than mating-side screwlock. This part is suitable only for applications where flange mounting location is not mechanically constrained.

The HARTING part 09641247232 operates at a reduced lower temperature limit of -20°C (versus -55°C) and uses a housing/shell flange. This part is suitable only for applications with operating temperatures above -20°C and where flange mounting location permits housing-side attachment.

Alternative Substitute (Thermal Derating Required):

The TE Connectivity part 5745434-8 provides electrical substitution with gold-plated contacts and mating-side standard screws but operates only to 105°C maximum (versus 125°C) and carries a 6A current rating (versus 7.5A). This part is suitable only for applications with maximum operating temperatures at or below 105°C and current requirements not exceeding 6A.

Compliance Consideration:

All substitute parts carry RoHS compliance certification, making them suitable for applications requiring regulatory compliance. The original DEMV09P500 is RoHS non-compliant; substitution with any listed part upgrades the assembly to compliant status.

Frequently Asked Questions (FAQ)

Q: Can I use 09661237803 or 09641247232 as direct replacements for DEMV09P500?

A: These HARTING parts are electrically compatible but feature housing/shell flange mounting instead of mating-side screwlock. They are mechanically compatible only if your PCB layout and mechanical assembly do not require mating-side flange attachment. Verify flange mounting location requirements before substitution.

Q: What is the difference between the four HARTING mating-side screwlock options (09661626813, 09661627813, 09661636813, 09661637813)?

A: All four parts are electrically and mechanically equivalent to DEMV09P500. Differences are limited to backset spacing specification (some specify 0.409" / 10.40mm, others unspecified) and minor feature variations (board lock, grounding indents). For standard D-Sub applications, any of these four parts are interchangeable.

Q: Is the TE Connectivity 5745434-8 suitable for my application?

A: The 5745434-8 is suitable only if your application operates at maximum 105°C and requires maximum 6A current. If your design requires the full 7.5A rating or operates above 105°C, this part is not appropriate. Verify thermal and current requirements before selection.

Q: Why do some substitute parts not specify contact finish?

A: Contact finish specifications are not provided in the manufacturer data for HARTING parts 09661237803, 09661626813, 09661627813, 09661636813, and 09661637813. The original DEMV09P500 specifies gold plating; contact the manufacturer directly if contact finish is a critical requirement for your application.

Q: Can I substitute DEMV09P500 with a part that operates only to -20°C instead of -55°C?

A: No, unless your application operates exclusively above -20°C. The DEMV09P500 is rated to -55°C; substitution with 09641247232 (rated -20°C minimum) reduces the operating envelope and may cause failure in cold environments.

Q: Are all these parts suitable for RoHS-regulated applications?

A: Yes. All substitute parts carry RoHS compliance certification (ROHS3 or RoHS Compliant). The original DEMV09P500 is RoHS non-compliant; any substitute part upgrades the assembly to compliant status for regulated markets.

Q: What is the inventory status for these substitute parts?

A: Current stock levels are: 5745434-8 (2054 pcs), 09661237803 (1127 pcs), 09661626813 (1039 pcs), 09661636813 (970 pcs), 09661627813 (862 pcs), 09641247232 (802 pcs), 09661637813 (673 pcs). Verify current availability with your supplier before design commitment.
