172-015-142R031 D-Sub Connector Equivalent & Substitute Parts

Part Overview

The 172-015-142R031 is a 15-position D-Sub plug connector with male pins, designed for panel mount through-hole applications using wire wrap termination. Manufactured by NorComp Inc. as part of the 172 M Series, this connector features a tin-plated steel shell with gold-flashed brass contacts and operates across a temperature range of -50°C to 100°C.

This part is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support legacy system maintenance and repairs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 172-015-142R031 is determined by strict equivalence across the following critical parameters:

• Connector style, type, and position count (D-Sub, Plug, Male Pins, 15-position)
• Physical layout and shell size (2-row, DA/A configuration)
• Mounting method and termination type (Panel Mount, Through Hole, Wire Wrap)
• Electrical performance (5A current rating, operating temperature range)
• Contact material and finish specification (Brass with gold flash)
• Flange configuration (Mating Side 4-40)
• Regulatory compliance (UL94 V-0, ROHS3)

The substitute part 172-015-143R031 maintains all critical functional and mechanical parameters. The primary difference is the shell material finish (nickel-plated steel versus tin-plated steel) and dielectric material composition, which do not affect connector interchangeability for standard D-Sub applications.

Parameter Comparison

Engineering Selection Recommendations

The 172-015-143R031 is the direct substitute for the obsolete 172-015-142R031. Both parts maintain identical electrical and mechanical specifications across all critical parameters required for D-Sub connector interchangeability.

The 172-015-143R031 is recommended for new designs and legacy system replacements due to its active product status and continued availability. Both parts are ROHS3 compliant and carry UL94 V-0 flammability certification, meeting current regulatory requirements.

The nickel-plated shell finish of the substitute part provides equivalent corrosion resistance and performance characteristics compared to the tin-plated finish of the original part in standard industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the 172-015-143R031 directly replace the 172-015-142R031 in existing designs?

A: Yes. Both connectors share identical position count, shell size, mounting configuration, termination method, and electrical ratings. The physical and functional compatibility is complete.

Q: What is the difference between tin-plated and nickel-plated shell finishes?

A: Both finishes provide corrosion resistance suitable for standard applications. Tin plating offers slightly lower contact resistance, while nickel plating provides enhanced durability in harsh environments. For typical D-Sub applications, both finishes perform equivalently.

Q: Are there any compatibility concerns with the dielectric material difference?

A: No. The main part uses polybutylene terephthalate (PBT) polyester, while the substitute uses polyamide (PA6T) nylon 6T. Both materials meet UL94 V-0 flammability requirements and are suitable for the specified operating temperature range and electrical performance.

Q: Is the 172-015-143R031 available in the same packaging as the original part?

A: The substitute part is supplied in tray packaging. Verify packaging requirements for your application and procurement process.

Q: Do both parts support the same wire gauge and current capacity?

A: Yes. Both connectors are rated for 5A current and support wire wrap termination with identical contact specifications.
