L17H1340121

Part Overview

The L17H1340121 is a 15-position D-Sub stacked connector manufactured by Amphenol ICC (Commercial Products). This connector functions as both a plug with male pins and a receptacle with female sockets, configured for right-angle through-hole mounting with solder termination. The product is currently active and available in inventory (769 pieces in stock). Finding alternative models becomes necessary when inventory constraints exist, when sourcing from alternative suppliers is preferred, or when specific operational requirements demand different electrical or mechanical characteristics than the primary part offers.

Key Parameters

Substitute Part Grouping Explanation

The NorComp Inc. part number 189-015-413R571 functions as a substitute for the L17H1340121 based on the following critical electrical and mechanical parameters:

Matching Parameters:

• Connector configuration: 15-position D-Sub stacked (15, 15 positions; 2, 2 rows)
• Shell size and layout: 2 (DA, A) on both plug and receptacle sides
• Mounting configuration: Right-angle orientation with through-hole capability
• Termination method: Solder attachment
• Contact system: Stamped brass construction with gold flash plating
• Flange feature: Mating side female screwlock (4-40)
• Backset spacing: 0.318" (8.08mm) identical pitch
• Safety certification: UL94 V-0 material flammability rating
• RoHS compliance: Both parts meet RoHS standards (RoHS Compliant and ROHS3 Compliant respectively)

Allowable Variations: The substitute part exhibits the following parameter differences within acceptable ranges for D-Sub connector substitution:

• Current rating difference: 189-015-413R571 rated for 5A versus L17H1340121 at 3A (higher capacity is acceptable)
• Shell finish: Nickel plated versus tin plated (both provide corrosion protection)
• Operating temperature upper limit: 105°C versus 125°C (slightly more restricted)
• Dielectric material: Polyamide (PA9T) versus thermoplastic glass-filled (both UL94 V-0 rated)
• Connector series designation: Different manufacturer series (189 versus 17H)

Parameter Comparison

Engineering Selection Recommendations

Both the L17H1340121 and 189-015-413R571 are active products with current manufacturing support and full RoHS compliance. The L17H1340121 is available in higher inventory (769 pieces) compared to the substitute (1288 pieces). Both parts maintain UL94 V-0 flammability certification, meeting safety requirements for electronics manufacturing.

Selection between these parts depends on operational constraints. The L17H1340121 supports higher operating temperatures (up to 125°C) and provides explicit 250V voltage rating specification. The 189-015-413R571 offers higher current capacity (5A versus 3A) and includes panel mount capability in addition to through-hole mounting, with ROHS3 certification indicating compliance with the latest RoHS regulations.

When ambient temperature environments exceed 105°C, the L17H1340121 is the appropriate selection. When current capacity requirements exceed 3A or when panel-mount functionality is required, the 189-015-413R571 is the suitable substitute.

Frequently Asked Questions (FAQ)

Q: What defines compatibility between the L17H1340121 and 189-015-413R571? A: Both connectors maintain identical 15-position D-Sub stacked configuration with matching shell size (DA, A), backset spacing (0.318"), and flange screwlock design. This ensures mechanical mating compatibility and equivalent electrical pathway architecture.

Q: Are the operating temperature ranges interchangeable? A: The temperature ranges differ: L17H1340121 operates to 125°C while 189-015-413R571 is rated to 105°C. The substitute is suitable for applications with maximum ambient temperatures at or below 105°C. Applications requiring higher temperature operation must use the L17H1340121.

Q: Does the difference in shell plating material affect performance? A: Both tin and nickel platings provide corrosion protection on the steel shell. Selection between them depends on specific environmental conditions. Nickel plating (189-015-413R571) offers enhanced resistance in certain chemical environments, while tin plating (L17H1340121) is standard for general-purpose applications.

Q: Can I use the 189-015-413R571 in a 3A current application? A: Yes. The 189-015-413R571 is rated for 5A, making it suitable for applications requiring 3A. A higher-rated component operates within safe operating margins.

Q: What is the significance of the voltage rating specification in the L17H1340121? A: The L17H1340121 specifies 250V rating, indicating verified dielectric withstand at that voltage level. The 189-015-413R571 voltage rating is not provided in the specification data, which may indicate standard D-Sub voltage ratings apply, but explicit confirmation with the manufacturer is required for high-voltage applications.

Q: Are both parts RoHS compliant? A: Yes. L17H1340121 is RoHS Compliant, and 189-015-413R571 is ROHS3 Compliant. ROHS3 represents the current regulatory iteration, though both satisfy RoHS requirements.

Q: What is the difference in dielectric material, and does it affect substitution? A: L17H1340121 uses thermoplastic with glass filling; 189-015-413R571 uses polyamide (PA9T, nylon 9T). Both achieve UL94 V-0 rating. Material selection affects mechanical properties and environmental resistance, but both provide equivalent flammability performance for standard applications.

Q: Does the 189-015-413R571 panel mount capability add functionality? A: The 189-015-413R571 supports panel mount mounting in addition to through-hole, providing installation flexibility. If your application uses only through-hole mounting, this additional capability does not affect substitution feasibility.
