172-015-142R021 D-Sub Connector Equivalent & Substitute Parts

Part Overview

The 172-015-142R021 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 currently listed as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this connector configuration.

Substitute Part Grouping Explanation

Substitution eligibility for the 172-015-142R021 is determined by strict equivalence across the following critical parameters:

Connector style, type, and pin configuration (D-Sub plug, male pins, 15 positions, 2 rows)
Shell size and connector layout (Size 2, DA/A configuration)
Mounting method and termination type (panel mount through-hole, wire wrap)
Electrical performance (5A current rating, operating temperature -50°C to 100°C)
Contact material and finish specifications (brass with gold flash)
Compliance certifications (UL94 V-0, ROHS3)

The substitute part 172-015-143R021 maintains full equivalence across all critical parameters. Variations in shell material finish (nickel-plated versus tin-plated), dielectric material composition, and voltage rating do not affect functional substitutability for this connector category, as these parameters remain within acceptable ranges for D-Sub plug applications.

Engineering Selection Recommendations

The 172-015-143R021 is the direct substitute for the obsolete 172-015-142R021. Both parts maintain identical functional specifications across all critical connector parameters and comply with the same regulatory standards (ROHS3, UL94 V-0, REACH Unaffected).

The primary distinction is product status: 172-015-143R021 is currently active and available in production quantities (844 pcs in stock), whereas 172-015-142R021 is obsolete with limited remaining inventory (767 pcs). For new designs or ongoing production requirements, 172-015-143R021 is the appropriate selection to ensure long-term supply chain continuity and compliance with current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Are these connectors mechanically interchangeable?

A: Yes. Both parts share identical shell size (Size 2, DA/A), pin configuration (15 positions, 2 rows), mounting type (panel mount through-hole), and termination method (wire wrap). They are fully mechanically interchangeable.

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

A: The main part features a tin-plated steel shell, while the substitute features a nickel-plated steel shell. Both finishes provide corrosion resistance and are suitable for D-Sub connector applications. The choice between them depends on specific environmental exposure requirements, which are not specified in the provided parameters.

Q: Can I use 172-015-143R021 in place of 172-015-142R021 in existing assemblies?

A: Yes. The substitute part maintains full electrical and mechanical compatibility. Both connectors support the same 5A current rating, operate across -50°C to 100°C, and feature identical contact material and finish specifications.

Q: Why is the main part listed as obsolete?

A: Product obsolescence typically reflects manufacturer discontinuation decisions. The substitute part 172-015-143R021 remains in active production and provides equivalent functionality for all specified applications.

Q: Are there packaging differences between these parts?

A: The main part packaging is not specified in the provided data. The substitute part is supplied in tray packaging. Confirm packaging requirements with your procurement or assembly process specifications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, UL94 V-0 rated, and REACH unaffected. They meet identical regulatory and safety requirements.
