171-015-201L021 D-Sub Receptacle Connector - Equivalent & Substitute Parts

Part Overview

The 171-015-201L021 is a 15-position D-Sub receptacle connector manufactured by NorComp Inc., designed for panel mount applications with female socket contacts and solder cup termination. This connector is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The connector operates across a temperature range of -50°C to 100°C and is rated for 5A current capacity with UL94 V-0 flammability compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 171-015-201L021 is determined by strict equivalence across the following critical parameters:

Connector configuration parameters: Connector type (receptacle, female sockets), number of positions (15), number of rows (2), and shell size/layout (2 DA, A) must remain identical.

Electrical and mechanical parameters: Current rating (5A), operating temperature range (-50°C ~ 100°C), termination method (solder cup), and wire gauge compatibility (20-28 AWG) must be maintained.

Material and compliance parameters: Dielectric material (PBT, glass filled), contact finish (gold), flammability rating (UL94 V-0), and regulatory compliance (ROHS3, REACH Unaffected) must be preserved.

The substitute part 171-015-203L021 meets all these criteria, with the primary difference being the shell material finish (nickel plated versus yellow chromate plated zinc) and product status transition from obsolete to active.

Parameter Comparison

Engineering Selection Recommendations

The 171-015-203L021 serves as a direct functional substitute for the obsolete 171-015-201L021. Both connectors maintain identical electrical specifications, mechanical configuration, and regulatory compliance certifications. The transition from obsolete to active product status makes the 171-015-203L021 the appropriate selection for new designs and ongoing system support.

The shell material finish difference (nickel plated versus yellow chromate plated zinc) does not affect electrical performance or mechanical compatibility. Both finishes provide equivalent corrosion resistance and contact reliability within the specified operating parameters. ROHS3 compliance and REACH unaffected status are maintained across both parts, ensuring regulatory continuity.

Frequently Asked Questions (FAQ)

Q: Can the 171-015-203L021 be used as a direct replacement for the 171-015-201L021?

A: Yes. Both connectors share identical connector type, position count, shell size, mounting configuration, termination method, current rating, temperature range, and dielectric material specifications. The parts are mechanically and electrically interchangeable.

Q: What is the difference between the shell finishes?

A: The main part uses yellow chromate plated zinc finish, while the substitute uses nickel plated finish. Both provide corrosion protection and maintain equivalent performance within the specified operating environment. The finish difference does not affect electrical or mechanical compatibility.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the 171-015-201L021 and 171-015-203L021 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: What is the significance of the product status change from obsolete to active?

A: The 171-015-203L021 is an active product with ongoing manufacturer support and availability. The 171-015-201L021 is obsolete, meaning it is no longer in production. For new designs and long-term system support, the active substitute part is recommended.

Q: Are the packaging formats compatible?

A: The main part packaging is not specified. The substitute part is supplied in tray packaging. Verify packaging requirements for your assembly process, as this may affect handling and installation procedures.

Q: Do both connectors support the same wire gauge range?

A: Yes. Both parts accommodate 20-28 AWG wire gauge, ensuring compatibility with existing wiring specifications and assembly processes.
