Amphenol ICC L17H1110121 D-Sub Connector: Equivalent & Substitute Parts

Part Overview

The Amphenol ICC L17H1110121 is a 9-position D-Sub stacked plug connector with right-angle solder termination, designed for signal applications requiring shielded, through-hole mounting. This connector features male pins, tin-plated steel shell with gold-flashed contacts, and operates across -55°C to 105°C with a 3A current rating at 250V. The part maintains Active product status with 1057 units in current inventory.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct functional replacement in applications where the connector footprint, pin configuration, and electrical performance remain constant.

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on parametric alignment with L17H1110121:

Parametric Equivalents (Amphenol ICC Series 17H): Parts L17H1110131, L17H2110127, and L17H2110131 share identical electrical and mechanical specifications with the main part. These connectors maintain the same 9-position stacked configuration, right-angle through-hole mounting, solder termination, 3A current rating, 250V voltage rating, tin-plated steel shell with gold-flashed contacts, and -55°C to 105°C operating range. All three parts are Active status with UL94 V-0 flammability rating and RoHS compliance. Substitution between these parts is based on matching: connector style (D-Sub stacked), pin count (9, 9), shell size (1 DE/E), contact type (signal), termination method (solder), and environmental specifications.

Similar Alternatives (NorComp Inc. Series 189): Parts 189-009-613R491, 189-009-613R571, and 189-009-613R691 provide functional alternatives with the following distinctions: these connectors feature nickel-plated steel shells instead of tin-plated, support higher 5A current rating, include panel mount capability in addition to through-hole mounting, and use polyamide (PA9T) nylon 9T dielectric material. These parts maintain the same 9-position stacked configuration, right-angle orientation, solder termination, gold-flashed contacts, and -55°C to 105°C operating temperature. All three are ROHS3 compliant and REACH unaffected. Substitution requires confirmation that the higher current rating and alternative shell finish are compatible with the application circuit requirements.

Engineering Selection Recommendations

For Direct Parametric Replacement:

Parts L17H1110131, L17H2110127, and L17H2110131 are suitable for direct substitution with L17H1110121 when inventory constraints or lead-time requirements necessitate alternative sourcing. All three maintain identical electrical specifications (3A current, 250V voltage), mechanical configuration (9-position stacked, right-angle through-hole), and environmental ratings (UL94 V-0, -55°C to 105°C). These parts carry Active product status and full RoHS compliance. Selection among these three Amphenol ICC equivalents should prioritize inventory availability: L17H2110127 currently maintains the highest stock level at 2905 units.

For Functional Alternatives with Enhanced Current Capacity:

The NorComp Inc. Series 189 connectors (189-009-613R491, 189-009-613R571, 189-009-613R691) provide functional alternatives when the application circuit can accommodate the higher 5A current rating and alternative shell finish specifications. These parts maintain the same 9-position stacked configuration, right-angle orientation, solder termination, and operating temperature range. The nickel-plated steel shell finish and polyamide dielectric material differ from the main part but remain compliant with UL94 V-0 flammability requirements and ROHS3 standards. Selection among NorComp alternatives should confirm that the application does not require the specific 250V voltage rating specification, as this parameter is not provided for the Series 189 parts.

Frequently Asked Questions (FAQ)

Q: Can L17H1110131 be used as a direct replacement for L17H1110121?

A: Yes. L17H1110131 shares identical electrical and mechanical specifications with L17H1110121, including 9-position stacked configuration, 3A current rating, 250V voltage rating, tin-plated steel shell with gold-flashed contacts, and -55°C to 105°C operating temperature. Both parts are Active status with UL94 V-0 flammability rating and RoHS compliance.

Q: What is the difference between Amphenol ICC Series 17H and NorComp Series 189 connectors?

A: The primary differences are shell finish (tin-plated versus nickel-plated), current rating (3A versus 5A), dielectric material (thermoplastic glass-filled versus polyamide nylon 9T), and mounting options (through-hole only versus panel mount plus through-hole). Both series maintain the same 9-position stacked configuration, right-angle orientation, solder termination, and operating temperature range.

Q: Are NorComp Series 189 connectors suitable for applications requiring 250V operation?

A: The NorComp Series 189 parts do not specify a voltage rating in the provided documentation. Confirmation of voltage compatibility with the application circuit is required before substitution. If the application mandates 250V operation, the Amphenol ICC Series 17H parts (L17H1110121, L17H1110131, L17H2110127, L17H2110131) are the specified alternatives.

Q: Can the higher 5A current rating of NorComp connectors be used in place of the 3A rating?

A: Yes, from a connector capacity perspective. The NorComp Series 189 connectors support 5A current, which exceeds the 3A requirement of L17H1110121. However, the application circuit design must be verified to ensure that the higher current capacity does not introduce unintended operational changes or safety concerns.

Q: What is the difference between the three NorComp Series 189 alternatives?

A: The three NorComp parts (189-009-613R491, 189-009-613R571, 189-009-613R691) differ in flange feature configuration: 189-009-613R491 and 189-009-613R691 feature housing/shell flanges with 4-40 mounting, while 189-009-613R571 features mating-side female screwlock (4-40). All three maintain identical electrical specifications, mounting options, and environmental ratings. Selection should be based on the specific flange and mounting requirements of the application.

Q: Are all substitute parts RoHS compliant?

A: Yes. The Amphenol ICC Series 17H parts (L17H1110121, L17H1110131, L17H2110127, L17H2110131) are RoHS Compliant. The NorComp Series 189 parts (189-009-613R491, 189-009-613R571, 189-009-613R691) are ROHS3 Compliant. Both compliance levels meet current regulatory requirements.

Q: What inventory levels should influence part selection?

A: Current inventory levels are: L17H2110127 (2905 units), 189-009-613R491 (2376 units), L17H2110131 (1548 units), 189-009-613R691 (1413 units), 189-009-613R571 (1213 units), L17H1110121 (1057 units), and L17H1110131 (966 units). For applications with extended lead-time requirements, L17H2110127 offers the highest availability among parametric equivalents.
