L17H2340121 D-Sub Connector Equivalent & Substitute Parts

Part Overview

The L17H2340121 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 in a right-angle, through-hole configuration. The part is currently active in production with 767 pieces in stock inventory.

Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable, when inventory constraints exist, or when design flexibility permits component interchange. Substitutes must maintain electrical and mechanical compatibility within the specified parameter ranges.

Substitute Part Grouping Explanation

Substitute parts for the L17H2340121 are identified based on strict electrical and mechanical compatibility criteria. The following parameters must align for a part to function as a direct substitute:

Critical Matching Parameters:

• Connector style: D-Sub - Stacked configuration
• Position count: 15 positions per row, 2 rows (15, 15)
• Shell size and layout: 2 (DA, A) designation
• Mounting type: Through hole, right angle orientation
• Connector type: Plug with male pins and receptacle with female sockets
• Termination method: Solder
• Backset spacing: 0.318" (8.08mm)
• Operating temperature range: -55°C ~ 105°C
• Contact material: Brass with gold finish
• Flange feature: Mating side, female screwlock (4-40)
• Features: Board lock, grounding indents, shielded configuration

Allowable Parameter Variations: Substitutes may differ in shell material finish (tin plated versus nickel plated), current rating capacity (within rated limits), dielectric material composition, and RoHS certification status, provided all critical parameters remain constant.

Engineering Selection Recommendations

L17H2340121 (Amphenol ICC):

• Primary selection for applications requiring 250V voltage rating specification
• Suitable for circuits with maximum current draw up to 3A
• RoHS Compliant status applies to standard regulatory environments
• Thermoplastic glass-filled dielectric material provides specified mechanical properties
• Tin-plated steel shell offers corrosion resistance in standard environments

178-015-413R571 (NorComp Inc.):

• Suitable as substitute when higher current capacity (5A) is required within the same connector footprint
• ROHS3 Compliant status meets current regulatory requirements
• Nickel-plated steel shell provides alternative corrosion resistance profile
• Polyamide (PA9T) nylon 9T dielectric material meets UL94 V-0 flammability rating
• Panel mount capability provides additional mounting flexibility beyond through-hole configuration
• Both parts maintain identical electrical and mechanical interface specifications

Both parts are active products with current manufacturing status and full inventory availability. Selection between these parts depends on application-specific current requirements, voltage rating necessity, and mounting configuration preferences.

Frequently Asked Questions (FAQ)

Q: Can the 178-015-413R571 directly replace the L17H2340121 in existing designs?

A: The 178-015-413R571 maintains identical connector geometry, pin configuration, spacing, and signal contact specifications. Direct mechanical and electrical substitution is supported. The higher current rating (5A versus 3A) and panel mount capability of the NorComp part provide additional design flexibility. Designs operating below 3A current levels and not requiring the 250V specification can use the substitute without modification.

Q: What are the differences in shell material finish between these parts?

A: The L17H2340121 features a tin-plated steel shell, while the 178-015-413R571 uses a nickel-plated steel shell. Both finishes provide corrosion resistance and electrical conductivity. Tin plating offers lower contact resistance, while nickel plating provides enhanced durability in high-vibration or harsh environments. Selection depends on application environmental conditions.

Q: Are both parts RoHS compliant?

A: Yes. The L17H2340121 is RoHS Compliant. The 178-015-413R571 is ROHS3 Compliant, which represents the current regulatory standard. Both parts meet RoHS requirements for restricted substance elimination.

Q: What is the significance of the dielectric material difference?

A: The L17H2340121 uses thermoplastic glass-filled material, while the 178-015-413R571 uses polyamide (PA9T) nylon 9T. Both materials achieve UL94 V-0 flammability rating and support the -55°C to 105°C operating temperature range. Material selection affects mechanical rigidity and environmental resistance characteristics. Both are suitable for standard industrial applications.

Q: Can these connectors be used interchangeably in high-current applications?

A: Applications requiring sustained current above 3A must use the 178-015-413R571, which is rated for 5A. The L17H2340121 is limited to 3A maximum current. Exceeding the rated current of either connector creates thermal and reliability risks.

Q: What mounting configurations are supported?

A: The L17H2340121 supports through-hole, right-angle mounting. The 178-015-413R571 supports panel mount, through-hole, and right-angle configurations, providing additional installation flexibility. Both maintain identical right-angle solder termination specifications.

Q: Is the 250V voltage rating of the L17H2340121 critical for substitution?

A: The L17H2340121 specifies 250V voltage rating. The 178-015-413R571 does not specify a voltage rating in the provided data. Applications requiring explicit 250V rating specification must use the L17H2340121. Applications operating below 250V can use either part.

Q: How do the backset spacing specifications affect compatibility?

A: Both parts maintain identical 0.318" (8.08mm) backset spacing. This specification defines the distance from the connector mounting surface to the contact plane. Identical spacing ensures mechanical interchangeability in PCB layouts and panel cutouts without design modification.

Q: What is the significance of the screwlock feature?

A: Both connectors feature female screwlock (4-40) on the mating side. This allows secure mechanical coupling between plug and receptacle using standard 4-40 screws, preventing accidental disconnection in vibration-prone or high-reliability applications.

Q: Are grounding indents and shielding equivalent between these parts?

A: Yes. Both the L17H2340121 and 178-015-413R571 include board lock, grounding indents, and shielded configuration. These features provide identical EMI/RFI shielding and mechanical retention characteristics.
