Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for D-Sub 9 position receptacle connectors is determined by the following critical parameters:

Core Compatibility Requirements (Must Match):

• Connector type: Receptacle, Female Sockets
• Number of positions: 9
• Number of rows: 2
• Shell size and layout: 1 (DE, E)
• Mounting type: Through Hole, Right Angle
• Termination method: Solder
• Material flammability rating: UL94 V-0

Allowable Variation Parameters:

• Current rating (7.5A primary; 6A and 3A acceptable for lower-power applications)
• Voltage rating (300V primary; 125V and 250V acceptable for lower-voltage applications)
• Operating temperature range (primary -55°C ~ 125°C; -55°C ~ 105°C acceptable for reduced temperature range)
• Shell material finish (Yellow Cadmium Plated, Tin Plated acceptable)
• Contact finish thickness (Flash or unspecified acceptable)
• Backset spacing (0.406" primary; 0.454" and 0.318" acceptable with mechanical design review)
• Flange feature configuration (Female Screwlock, Standard Screws, Housing/Shell Unthreaded acceptable)
• Dielectric material (Thermoplastic, Polyamide, Glass Filled acceptable)
• RoHS compliance status (non-compliant, ROHS3 Compliant, RoHS Compliant all acceptable)

The three identified substitute parts meet all core compatibility requirements and fall within allowable variation parameters for specific application scenarios.

Parameter Comparison

Engineering Selection Recommendations

5745438-1 (TE Connectivity AMPLIMITE HDP-20): This substitute is suitable for applications where voltage requirements do not exceed 125V and current does not exceed 6A. The part is ROHS3 compliant and operates across the reduced temperature range of -55°C to 105°C. Backset spacing of 0.454" (11.53mm) requires PCB layout verification. Standard screws (4-40) replace the female screwlock configuration. Packaging is supplied in trays. This option provides improved RoHS compliance status compared to the primary part.

5745438-4 (TE Connectivity AMPLIMITE HDP-20): Functionally identical to 5745438-1 with the same electrical ratings (6A, 125V) and operating temperature range (-55°C ~ 105°C). RoHS compliance status is listed as compliant. The primary distinction is bulk packaging rather than tray packaging, and higher inventory availability (1531 units). Backset spacing and flange configuration match 5745438-1. This option is suitable for high-volume procurement scenarios.

L77SDE09SA4CH (Amphenol ICC SD Series): This substitute accommodates applications with current requirements of 3A or less and voltage ratings up to 250V. Operating temperature range matches the primary part (-55°C ~ 125°C). Backset spacing of 0.318" (8.08mm) is significantly reduced and requires mechanical design verification. The unthreaded housing/shell flange differs from the primary part's female screwlock configuration. RoHS compliance is confirmed. This option is suitable for lower-power signal applications with tighter mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can 5745438-1 or 5745438-4 be used as direct replacements for DEMV09S500M?

A: These parts are functionally compatible for applications where current does not exceed 6A and voltage does not exceed 125V. The reduced operating temperature range (-55°C ~ 105°C versus -55°C ~ 125°C) must be verified against application requirements. Backset spacing differs (0.454" versus 0.406"), requiring PCB layout confirmation. Flange configuration changes from female screwlock to standard screws.

Q: What are the key differences in backset spacing, and does this affect compatibility?

A: Backset spacing is the distance from the mounting plane to the rear of the connector. DEMV09S500M specifies 0.406" (10.30mm), while 5745438-1 and 5745438-4 specify 0.454" (11.53mm), and L77SDE09SA4CH specifies 0.318" (8.08mm). These differences affect PCB layout and mounting depth. Mechanical design review is required to confirm compatibility with existing board layouts and enclosure constraints.

Q: Is L77SDE09SA4CH suitable for high-current applications?

A: No. L77SDE09SA4CH is rated for 3A maximum current, compared to 7.5A for DEMV09S500M. This substitute is appropriate only for low-power signal applications. Applications requiring current above 3A must use DEMV09S500M, 5745438-1, or 5745438-4.

Q: What is the difference between female screwlock and standard screws flange configurations?

A: DEMV09S500M features a female screwlock (4-40) on the mating side, allowing threaded engagement with mating connector screws. Substitutes 5745438-1 and 5745438-4 use standard screws (4-40), which may require different mating connector specifications. L77SDE09SA4CH uses an unthreaded housing/shell configuration. Mating connector compatibility must be verified before substitution.

Q: Are there RoHS compliance implications when substituting parts?

A: DEMV09S500M is RoHS non-compliant. Substitutes 5745438-1 (ROHS3 Compliant), 5745438-4 (RoHS Compliant), and L77SDE09SA4CH (RoHS Compliant) offer improved compliance status. If RoHS compliance is a design requirement, any of the three substitutes are acceptable. If the application permits non-compliant parts, the primary part remains valid.

Q: What packaging options are available?

A: DEMV09S500M and 5745438-1 are supplied in trays. 5745438-4 is supplied in bulk packaging. L77SDE09SA4CH is supplied in trays. Packaging selection may affect procurement logistics and unit cost.

Q: Can multiple substitutes be used interchangeably within a single design?

A: No. Each substitute has distinct electrical ratings, mechanical dimensions, and flange configurations. A single design must standardize on one connector model. Mixing different connector types in the same application introduces compatibility and serviceability risks.
