D-Sub 9 Position Plug Connector D09P91C6PI9CLF Equivalent & Substitute Parts

Part Overview

The D09P91C6PI9CLF is a 9 position D-Sub plug connector manufactured by Amphenol ICC (FCI) in the Delta D series. This through-hole mounted connector features male pins with press-fit termination and is designed for signal applications requiring a 300V rating and 5A current capacity. The part is currently active in production with 944 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, experiences supply constraints, or when design requirements allow for alternative configurations that meet the same electrical and mechanical specifications. The substitute identified (09661646716 from HARTING) has transitioned to obsolete status, making it suitable only for legacy system maintenance or when inventory availability is critical.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for D-Sub connectors is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Connector style (D-Sub)
• Connector type (Plug, Male Pins)
• Number of positions (9)
• Number of rows (2)
• Shell size and layout (1 / DE, E)
• Mounting type (Through Hole)
• Termination method (Press-Fit)

Electrical Compatibility Parameters:

• Current rating must be equal to or greater than the original specification
• Voltage rating must be equal to or greater than the original specification
• Operating temperature range must encompass or match the original range

The substitute part 09661646716 (HARTING) maintains all critical matching parameters and electrical compatibility. The current rating increases from 5A to 6.5A, and the operating temperature range remains identical at -55°C to 125°C. Material flammability rating (UL94 V-0) is preserved.

Engineering Selection Recommendations

Primary Selection: D09P91C6PI9CLF (Amphenol ICC)

This part is the recommended choice for new designs and ongoing production. It maintains active product status with confirmed inventory availability (944 units in stock). RoHS compliance is established, and all electrical and mechanical specifications are fully documented. The part is suitable for applications requiring 5A at 300V across the -55°C to 125°C operating range.

Substitute Selection: 09661646716 (HARTING)

This part is suitable only for legacy system maintenance or replacement scenarios where the original part is no longer available. The part has transitioned to obsolete status and should not be selected for new designs. However, it meets all critical mechanical and electrical compatibility requirements, with an increased current rating of 6.5A providing additional margin. ROHS3 compliance indicates updated regulatory alignment. Inventory availability is higher (1095 units), which may be relevant for legacy support applications.

Frequently Asked Questions (FAQ)

Q: Can the HARTING 09661646716 be used as a direct replacement for the Amphenol ICC D09P91C6PI9CLF?

A: Yes, from a mechanical and electrical standpoint. Both connectors share identical shell size (1 / DE, E), position count (9), row configuration (2), mounting type (Through Hole), and termination method (Press-Fit). The HARTING part supports a higher current rating (6.5A vs. 5A) and maintains the same operating temperature range (-55°C to 125°C) and flammability rating (UL94 V-0). However, the HARTING part is obsolete, making it unsuitable for new designs.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching: connector style (D-Sub), connector type (Plug, Male Pins), position count (9), row count (2), shell size and layout (1 / DE, E), mounting type (Through Hole), and termination method (Press-Fit). Electrical parameters must meet or exceed the original: current rating (minimum 5A), voltage rating (minimum 300V), and operating temperature range (-55°C to 125°C).

Q: Are there differences in contact material or finish between these parts?

A: Yes. The Amphenol ICC part specifies phosphor bronze contacts with gold finish (30.0µin / 0.76µm thickness). The HARTING part specifies copper alloy contacts with unspecified finish. These material differences may affect performance in specific applications, particularly regarding corrosion resistance and contact reliability over extended operating life.

Q: What is the significance of the product status difference?

A: The Amphenol ICC D09P91C6PI9CLF is active in production, ensuring long-term availability and continued support. The HARTING 09661646716 is obsolete, indicating it is no longer manufactured and available only through existing inventory channels. For new designs, the active part is the appropriate selection.

Q: How do the RoHS compliance levels differ?

A: The Amphenol ICC part is RoHS Compliant (standard RoHS directive). The HARTING part is ROHS3 Compliant, indicating compliance with the updated RoHS 3 directive. Both meet current regulatory requirements, though ROHS3 represents a more recent compliance standard.
