DEML09S500M D-Sub 9 Position Receptacle Connector

Part Overview

The DEML09S500M is a 9 position D-Sub receptacle connector manufactured by Amphenol ICC (FCI) in the DM HE501 series. This right-angle, through-hole solder termination connector features female sockets with gold-plated phosphor bronze contacts rated for 7.5A per contact at 300V. The connector is actively produced and maintains 1088 units in current inventory stock.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits functional alternatives within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DEML09S500M is determined by strict alignment of the following parameters:

Critical Parameters (Must Match):

• Connector style: D-Sub
• Connector type: Receptacle, Female Sockets
• Number of positions: 9
• Number of rows: 2
• Shell size, connector layout: 1 (DE, E)
• Mounting type: Through Hole, Right Angle
• Termination method: Solder
• Contact material: Phosphor Bronze
• Contact finish: Gold
• Flammability rating: UL94 V-0

Allowable Variation Parameters:

• Current rating: Substitute must meet or exceed 7.5A per contact
• Voltage rating: Substitute must meet or exceed 300V
• Operating temperature range: Substitute must encompass -55°C to 125°C
• Shell material and finish: May differ
• Dielectric material: May differ
• Backset spacing: Minor variations permitted within connector family
• Flange feature design: May differ
• RoHS compliance status: May differ

The three identified substitute parts (5745438-1, 5745438-4, and L77SDE09SA4CH) maintain all critical parameters while presenting variations in current rating, voltage rating, operating temperature range, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

5745438-1 (TE Connectivity AMP Connectors, AMPLIMITE HDP-20 Series)

This substitute maintains all critical connector parameters. The current rating of 6A per contact is lower than the DEML09S500M specification of 7.5A per contact. The voltage rating of 125V is lower than the 300V specification. The operating temperature range of -55°C to 105°C does not encompass the full 125°C upper limit. This part is ROHS3 compliant. Selection is appropriate for applications where current and voltage requirements do not exceed the substitute specifications and where RoHS compliance is required.

5745438-4 (TE Connectivity AMP Connectors, AMPLIMITE HDP-20 Series)

This substitute is identical to 5745438-1 in electrical and mechanical specifications. The packaging differs (Bulk versus Tray). The RoHS compliance status is listed as RoHS Compliant with REACH status as Vendor Undefined. Current inventory is 1531 units. Selection criteria are equivalent to 5745438-1.

L77SDE09SA4CH (Amphenol ICC Commercial Products, SD Series)

This substitute maintains all critical connector parameters. The current rating of 3A per contact is significantly lower than the DEML09S500M specification of 7.5A per contact. The voltage rating of 250V is lower than the 300V specification. The operating temperature range of -55°C to 125°C matches the original specification. This part is RoHS compliant. Selection is appropriate only for applications where current requirements do not exceed 3A per contact and voltage requirements do not exceed 250V.

Frequently Asked Questions (FAQ)

Q: Can 5745438-1 or 5745438-4 be used as direct replacements for DEML09S500M?

A: These parts maintain mechanical and connector type compatibility. However, the current rating of 6A per contact is lower than the DEML09S500M rating of 7.5A per contact, and the voltage rating of 125V is lower than 300V. Selection depends on whether the application circuit operates within these reduced electrical specifications.

Q: What is the primary limitation of L77SDE09SA4CH as a substitute?

A: The current rating of 3A per contact is substantially lower than the DEML09S500M specification of 7.5A per contact. This part is suitable only for low-current signal applications. The voltage rating of 250V is also lower than the original 300V specification.

Q: Are there RoHS compliance differences between the main part and substitutes?

A: The DEML09S500M is RoHS non-compliant. Both 5745438-1 and 5745438-4 are RoHS compliant, as is L77SDE09SA4CH. If RoHS compliance is a design requirement, any of the three substitutes may be selected based on electrical parameter compatibility.

Q: Do the substitutes support the full operating temperature range of the DEML09S500M?

A: The DEML09S500M operates from -55°C to 125°C. The TE Connectivity parts (5745438-1 and 5745438-4) operate from -55°C to 105°C, which does not encompass the full upper temperature limit. The L77SDE09SA4CH operates from -55°C to 125°C and matches the original specification.

Q: What packaging options are available?

A: DEML09S500M, 5745438-1, and L77SDE09SA4CH are supplied in Tray packaging. Part 5745438-4 is supplied in Bulk packaging. Packaging selection may affect handling, storage, and procurement processes.

Q: Are all substitutes mechanically compatible with the same PCB footprint?

A: All parts maintain the same connector style (D-Sub), shell size (1/DE, E), mounting type (Through Hole, Right Angle), and termination method (Solder). Backset spacing varies slightly between parts (0.406" for DEML09S500M, 0.454" for TE Connectivity parts, and 0.318" for L77SDE09SA4CH). PCB layout verification is required to confirm mechanical fit.
