Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DEMME9SF is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria (Must Match):

• Connector style: D-Sub
• Connector type: Receptacle, Female Sockets
• Number of positions: 9
• Number of rows: 2
• Shell size and layout: 1 (DE, E)
• Mounting type: Panel Mount, Through Hole, Right Angle
• Termination method: Solder
• Contact type: Signal
• Contact finish: Gold
• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)

Secondary Compatibility Parameters (Allowable Variation):

• Current rating: Substitute must meet or exceed 7.5A requirement
• Operating temperature: Substitute must support minimum -55°C to 150°C range
• Shell material and finish: Variations acceptable (Yellow Chromate Plated Zinc vs. Tin Plated)
• Dielectric material: Variations acceptable (PCT vs. Polyester Glass Filled vs. PBT/Polyester)
• Contact material: Variations acceptable (Copper Alloy vs. Phosphor Bronze)
• RoHS compliance: Variations acceptable
• Flange feature configuration: Variations acceptable (Board Side vs. Housing/Shell)

The three identified substitute parts (1-106505-2, 5-106505-2, 8-1393480-1) satisfy all primary criteria and maintain functional equivalence within the specified parameter tolerances.

Parameter Comparison

Engineering Selection Recommendations

1-106505-2 (TE Connectivity AMPLIMITE HD-20): This substitute maintains full functional equivalence with the DEMME9SF across all primary substitution criteria. The part achieves ROHS3 compliance and provides higher inventory availability (1990 units). Operating temperature range is reduced to -55°C to 105°C, which represents a 45°C reduction at the upper limit. Current rating is 6A versus 7.5A on the original part. Flange feature includes board lock functionality. Suitable for applications where the reduced temperature ceiling and current rating do not conflict with system requirements and where RoHS3 compliance is required.

5-106505-2 (TE Connectivity AMPLIMITE HD-20, Bulk Packaging): Functionally identical to 1-106505-2 with equivalent electrical and mechanical specifications. Packaging differs (bulk versus tray). Flange feature is unthreaded versus 4-40 threaded. ROHS3 compliant. Appropriate for high-volume procurement where bulk packaging reduces per-unit cost and where unthreaded flange mounting is compatible with board design.

8-1393480-1 (TE Connectivity AMPLIMITE HD-20): This substitute meets all primary substitution criteria but exhibits significant deviations in secondary parameters. Current rating is substantially reduced to 2.2A, representing a 71% reduction from the DEMME9SF specification. Operating temperature range extends to -55°C to 125°C, providing 25°C additional high-temperature capability compared to 1-106505-2 and 5-106505-2 but remaining 25°C below the original part. Connector color is gray rather than black. RoHS compliant. Backset spacing differs at 0.371" versus 0.406" on other substitutes. Selection of this part is restricted to applications where current requirements do not exceed 2.2A and where the reduced current rating is acceptable.

Compliance Considerations: All three substitute parts achieve RoHS compliance (ROHS3 or RoHS Compliant status), whereas the DEMME9SF is RoHS non-compliant. This represents a significant advantage for applications subject to RoHS regulatory requirements. Selection should account for system-level compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can 1-106505-2 be used as a direct replacement for DEMME9SF in all applications?

A: 1-106505-2 satisfies all primary substitution criteria and maintains mechanical and electrical compatibility. However, two secondary parameters differ: operating temperature range is reduced from -55°C to 150°C to -55°C to 105°C, and current rating is reduced from 7.5A to 6A. Direct substitution is appropriate only when system operating conditions remain within -55°C to 105°C and current draw does not exceed 6A.

Q: What is the difference between 1-106505-2 and 5-106505-2?

A: Both parts are functionally identical AMPLIMITE HD-20 series connectors with matching electrical and mechanical specifications. The primary differences are packaging format (tray versus bulk) and flange feature configuration (4-40 threaded versus unthreaded). Selection between these parts depends on procurement volume requirements and board-level mounting interface design.

Q: Why is the current rating of 8-1393480-1 significantly lower than the other substitutes?

A: The 8-1393480-1 is specified at 2.2A current rating, which is a design characteristic of this particular connector variant within the AMPLIMITE HD-20 series. This part is suitable only for applications where signal-level currents do not exceed 2.2A. For applications requiring 6A or higher current capacity, 1-106505-2 or 5-106505-2 are appropriate selections.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts (1-106505-2, 5-106505-2, and 8-1393480-1) achieve RoHS compliance status (ROHS3 Compliant or RoHS Compliant), whereas the DEMME9SF is RoHS non-compliant. This represents a regulatory advantage for applications subject to RoHS directives.

Q: What is the impact of different shell material finishes on connector performance?

A: The DEMME9SF features yellow chromate plated zinc finish, while all substitute parts use tin plated finish. Both finishes provide corrosion resistance and electrical conductivity suitable for solder termination. The finish difference does not affect electrical performance or mechanical compatibility. Selection may be influenced by environmental exposure conditions and specific corrosion resistance requirements.

Q: Can 8-1393480-1 be used in high-current applications?

A: No. The 8-1393480-1 is rated for 2.2A maximum continuous current, which is insufficient for applications requiring 6A or higher. For high-current signal distribution, 1-106505-2 or 5-106505-2 are the appropriate selections, both rated at 6A.

Q: What is the significance of the backset spacing parameter?

A: Backset spacing defines the distance from the connector mounting face to the contact insertion point. The DEMME9SF does not specify this parameter. Substitute parts 1-106505-2 and 5-106505-2 specify 0.406" (10.30mm), while 8-1393480-1 specifies 0.371" (9.43mm). This parameter affects board layout and mating connector alignment. Verify backset spacing compatibility with existing board designs before part selection.

Q: Are there any temperature-related limitations when substituting parts?

A: Yes. The DEMME9SF operates from -55°C to 150°C. Substitutes 1-106505-2 and 5-106505-2 operate from -55°C to 105°C, representing a 45°C reduction at the upper temperature limit. Substitute 8-1393480-1 operates from -55°C to 125°C, providing 25°C additional high-temperature capability compared to the other substitutes but remaining 25°C below the original specification. Applications requiring operation above 105°C should use 8-1393480-1 or retain the original DEMME9SF.
