172-E15-202-021 D-Sub Receptacle Connector Equivalent & Substitute Parts

Part Overview

The 172-E15-202-021 is a 15-position D-Sub receptacle connector manufactured by NorComp Inc., designed for panel mount applications with female socket contacts. This connector is part of the 172-E series and features solder cup termination for permanent circuit board integration.

The main part (172-E15-202-021) is currently in stock with 808 units available. However, alternative part numbers within the same series provide equivalent functionality with different material specifications and availability status. Identifying suitable substitutes is necessary for supply chain flexibility, long-term component sourcing, and design optimization across production batches.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 172-E15-202-021 is determined by strict equivalence across the following critical parameters:

• Connector style, type, and position count (D-Sub, 15-position receptacle)
• Physical form factor and mounting configuration (panel mount, 2-row layout, shell size 2)
• Electrical performance (5A current rating, signal contact type)
• Termination method (solder cup)
• Material composition and environmental ratings (PBT dielectric, brass contacts, UL94 V-0, operating temperature -50°C ~ 100°C)
• Regulatory compliance (ROHS3 compliant, REACH unaffected)

The substitute parts 172-E15-202R021 and 172-E15-203R021 meet all these criteria. Differences exist only in shell material finish (tin plated versus nickel plated) and product status, which do not affect functional interchangeability in equivalent circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers are functionally equivalent for applications requiring a 15-position D-Sub panel mount receptacle with solder cup termination and the specified electrical and environmental parameters.

For new designs and long-term production sourcing, 172-E15-203R021 is the preferred selection. This part carries Active product status, ensuring continued manufacturer support and availability. The nickel-plated shell finish provides enhanced corrosion resistance compared to tin plating, extending service life in demanding environments.

The 172-E15-202R021 carries Obsolete status and should be used only when existing inventory must be consumed or when legacy design compatibility is required. The 172-E15-202-021 remains in current production with adequate stock levels and is suitable for immediate procurement needs.

Shell material finish (tin versus nickel plating) represents the only functional difference among these parts. Selection between tin and nickel finishes depends on application environment and corrosion resistance requirements, not on electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can 172-E15-202R021 and 172-E15-203R021 be used interchangeably with 172-E15-202-021 in the same circuit?

A: Yes. All three parts are electrically and mechanically equivalent. They share identical connector geometry, pin configuration, current rating, operating temperature range, and contact materials. The only difference is shell material finish (tin plated versus nickel plated), which does not affect circuit functionality.

Q: What is the significance of the shell material finish difference?

A: The shell material finish affects corrosion resistance and environmental durability. Nickel plating (172-E15-203R021) provides superior corrosion resistance in humid, salt-spray, or chemically aggressive environments. Tin plating (172-E15-202-021 and 172-E15-202R021) is suitable for standard indoor and controlled industrial applications.

Q: Why is 172-E15-202R021 marked as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production of this part number. Existing inventory may still be available, but future procurement cannot be guaranteed. For new designs, use 172-E15-203R021 (Active status) to ensure long-term supply chain continuity.

Q: Are all three parts ROHS3 compliant?

A: Yes. All three part numbers meet ROHS3 compliance requirements and are REACH unaffected, making them suitable for applications subject to these regulatory standards.

Q: What packaging format is used for the substitute parts?

A: Both substitute parts (172-E15-202R021 and 172-E15-203R021) are supplied in Tray packaging, suitable for automated assembly and high-volume production environments.

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

A: Yes. All three parts are rated for operating temperatures from -50°C to 100°C, supporting both cryogenic and elevated-temperature industrial applications within this range.
