DLS1SS5AN21X Equivalent and Substitute Parts

Part Overview

The DLS1SS5AN21X is a 9-position D-Sub stacked receptacle connector manufactured by Amphenol CONEC. This female sockets connector is configured with right-angle board edge mounting and solder termination for Through Hole applications. The part is currently in active production status with 897 pieces available in stock inventory.

Identification of substitute components becomes necessary when the primary part reaches end-of-life status, when inventory is exhausted, or when alternative sourcing is required to optimize supply chain logistics. The substitute parts listed below provide equivalent electrical and mechanical functionality within specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters that must match or remain within acceptable tolerance across all candidate parts:

Mandatory Matching Parameters:

• Connector style (D-Sub - Stacked)
• Connector type (Receptacle, Female Sockets)
• Position count (9, 9 configuration with 2 rows)
• Shell size and layout (1 DE, E)
• Mounting orientation (Right Angle)
• Termination method (Solder)
• Contact type (Signal)
• Material flammability rating (UL94 V-0)

Allowable Parameter Variations:

• Shell material finish: Tin Plated or Nickel Plated
• Current rating: Substitute parts rated at 5A meet the 7.5A requirement of the main part when applied to lower-current circuit designs
• Operating temperature ceiling: -55°C minimum is maintained; upper limit ranges from 105°C to 125°C
• Backset spacing: Tolerance band of 0.318" to 0.322" (8.08mm to 8.18mm) permits cross-compatibility
• Dielectric material: PBT Glass Filled or PA9T Nylon 9T both provide required electrical isolation
• Contact material: Copper Alloy or Brass both suitable for signal applications

All substitute parts (189-009-513R491, 189-009-513R571, 189-009-513R691) maintain ROHS3 compliance and EAR99 classification consistent with the main part.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and ROHS3 compliance, ensuring support for current and future procurement cycles. Selection among the NorComp 189 series alternatives should be based on the following considerations:

189-009-513R491: Suitable for applications where panel mounting with standard housing/shell flange is required. Lower current rating of 5A is acceptable for signal-level applications.

189-009-513R571: Specified for designs requiring female screwlock mating side connectors. This variant provides enhanced mating security and is preferred when vibration isolation or frequent disconnect cycles are expected.

189-009-513R691: Designated for applications with standard housing/shell mounting flanges, offering the highest inventory availability (1652 pieces) among NorComp substitutes.

The primary distinction between the Amphenol CONEC DLS1SS5AN21X and all NorComp alternatives is the mounting type transition from board edge to panel mount configuration. Design verification of PCB layout and panel cutout specifications is required prior to implementation of any NorComp substitute.

Frequently Asked Questions (FAQ)

Q: Can the NorComp parts directly replace the Amphenol CONEC DLS1SS5AN21X in existing designs?

A: Direct physical interchange depends on the mounting configuration. The main part supports board edge mounting, while all NorComp substitutes are panel mount only. PCB layout and panel cutout geometry must be evaluated for compatibility.

Q: What is the significance of the 5A versus 7.5A current rating difference?

A: The NorComp substitutes are rated at 5A, compared to 7.5A for the main part. For signal-level D-Sub applications, this rating difference is not limiting. Current-carrying capacity becomes relevant only in power distribution designs; review application current requirements against the 5A specification of substitute parts.

Q: Are the operating temperature ranges compatible?

A: The main part operates to 125°C, while NorComp substitutes are rated to 105°C. For applications operating above 105°C, the main part specification must be retained. Standard commercial electronics applications operate within the 105°C envelope.

Q: What are the flange feature differences among the three NorComp variants?

A: 189-009-513R491 and 189-009-513R691 both feature housing/shell 4-40 flanges, while 189-009-513R571 incorporates a mating side female screwlock mechanism. The screwlock variant provides mechanical strain relief for mated connectors.

Q: How does the backset spacing tolerance affect compatibility?

A: Backset spacing of 0.318" (8.08mm) for NorComp parts versus 0.322" (8.18mm) for the main part represents a 0.004" (0.10mm) difference within typical PCB manufacturing tolerances and does not impact functional compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts meet ROHS3 compliance and maintain REACH unaffected status, consistent with the main part specification.
