L171370 D-Sub Backshell Connector Equivalent & Substitute Parts

Part Overview

The L171370 is a 9-position two-piece backshell connector manufactured by Amphenol ICC (Commercial Products). This component is designed for D-Sub connectors with 180° cable exit orientation and unshielded configuration. The part is classified as obsolete, necessitating identification of active equivalent alternatives for ongoing procurement and system integration. Substitute parts must maintain compatibility with 9-position D-Sub and HD15-position connector shells while preserving mechanical and electrical interface requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the L171370 are identified based on the following critical parameters that determine functional compatibility:

Core Compatibility Parameters:

• Number of Positions: 9
• Compatible Shell Size: E
• Compatible D-Sub Size: 9pos and HD15pos
• Cable Type: Round
• Cable Exit: 180°
• Accessory Type: Two Piece Backshell
• Series: L17

Allowable Variations: Substitute parts may differ in shielding configuration (shielded versus unshielded), primary material composition (plastic versus metal), and hardware features (cable clamp versus strain relief), provided all core compatibility parameters remain constant. These variations address different electromagnetic interference requirements and mechanical mounting preferences while maintaining interface compatibility with the same connector shell sizes and positions.

Parameter Comparison

Engineering Selection Recommendations

L17DTZK09KFM is the active substitute for the obsolete L171370. Both components are manufactured by Amphenol ICC (Commercial Products) within the L17 series and maintain identical core compatibility parameters: 9-position configuration, shell size E, 180° cable exit, and round cable type.

The L17DTZK09KFM differs in two material and feature aspects:

1. Shielding Configuration: The substitute provides shielded construction compared to the unshielded main part. Shielded backshells provide electromagnetic interference (EMI) attenuation and are suitable for applications requiring enhanced signal integrity.

2. Material Composition: The substitute uses metal construction with strain relief hardware, whereas the main part uses thermoplastic material with cable clamp hardware. Metal construction provides improved durability and grounding characteristics.

Both parts maintain RoHS compliance and MSL 1 (Unlimited) moisture sensitivity ratings, ensuring compatibility with standard manufacturing and storage environments. The substitute part is currently in active production status with confirmed inventory availability (880 pieces), supporting long-term procurement reliability.

Frequently Asked Questions (FAQ)

Q: Can L17DTZK09KFM directly replace L171370 in existing assemblies?

A: Yes. Both parts share identical core compatibility parameters: 9-position configuration, shell size E, 180° cable exit, and round cable type. The parts are mechanically and electrically interchangeable at the connector interface level. The shielded and metal construction of the substitute provides additional performance characteristics without compromising interface compatibility.

Q: What is the functional difference between the unshielded L171370 and shielded L17DTZK09KFM?

A: The L171370 is unshielded with plastic construction, suitable for applications without EMI requirements. The L17DTZK09KFM is shielded with metal construction, providing electromagnetic interference attenuation and improved grounding. Selection depends on application-specific EMI performance requirements.

Q: Are both parts compatible with 9-position and HD15-position D-Sub connectors?

A: Yes. Both L171370 and L17DTZK09KFM are compatible with shell size E and support both 9-position and HD15-position D-Sub connector configurations.

Q: What is the significance of the obsolete status of L171370?

A: The obsolete status indicates that L171370 is no longer in active production. L17DTZK09KFM is the active equivalent available for new designs and ongoing procurement. Existing inventory of L171370 remains available (1001 pieces), but future supply is not guaranteed.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both L171370 and L17DTZK09KFM are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, meeting standard environmental and regulatory requirements.

Q: What hardware differences exist between the two parts?

A: L171370 includes assembly hardware and cable clamp. L17DTZK09KFM includes assembly hardware, strain relief, and mating screws. The strain relief in the substitute provides enhanced cable retention and mechanical stability.
