172-E15-101R021 Equivalent & Substitute Parts

Part Overview

The 172-E15-101R021 is a 15-position D-Sub plug connector with male pins, designed for panel mount applications. Manufactured by NorComp Inc., this connector features solder cup termination and is rated for 5A current at operating temperatures from -50°C to 100°C. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations where compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 172-E15-101R021 is determined by the following core parameters:

• Connector Style & Type: Must be D-Sub plug with male pins
• Position & Row Configuration: Must maintain 15 positions in 2-row layout (Shell Size 2, DA/A)
• Termination Method: Must use solder cup termination
• Current Rating: Minimum 5A capability
• Operating Temperature Range: Must encompass or exceed -50°C to 100°C
• Flange Feature: Cable side (4-40) mounting requirement
• Contact Material & Finish: Brass with gold finish

The 172-E15-103R021 qualifies as a direct equivalent, differing only in shell finish (nickel vs. chromate) and compliance status. The DAMO15P043 functions as a substitute with higher current rating (7.5A) and extended temperature range (-55°C to 125°C), though it uses free hanging mounting rather than panel mount configuration.

Engineering Selection Recommendations

172-E15-103R021 is the preferred substitute for direct replacement applications. This part maintains identical electrical and mechanical specifications as the original 172-E15-101R021, with the primary differences being shell finish (nickel plating vs. yellow chromate) and active product status. The 172-E15-103R021 achieves ROHS3 compliance, making it suitable for applications requiring modern regulatory adherence. Both parts are manufactured by NorComp Inc. within the same 172-E series, ensuring design compatibility.

DAMO15P043 serves as an alternative substitute where enhanced performance margins are acceptable. This Amphenol ICC part provides higher current rating (7.5A vs. 5A) and extended operating temperature range (-55°C to 125°C vs. -50°C to 100°C), offering greater operational headroom. However, the mounting configuration differs (free hanging vs. panel mount), requiring mechanical redesign of the installation interface. The DAMO15P043 includes harsh environment ingress protection and 300V voltage rating, specifications not provided for the original part.

Selection between these substitutes depends on application requirements: choose 172-E15-103R021 for direct mechanical and electrical compatibility with regulatory compliance; choose DAMO15P043 when enhanced current capacity, temperature range, or environmental protection is required and mechanical redesign is feasible.

Frequently Asked Questions (FAQ)

Q: Can the 172-E15-103R021 directly replace the 172-E15-101R021 without modification?

A: Yes. Both connectors share identical pin configuration (15 positions, 2 rows, Shell Size 2), current rating (5A), operating temperature range (-50°C to 100°C), termination method (solder cup), and panel mount design. The shell finish difference (nickel vs. chromate) does not affect electrical or mechanical compatibility.

Q: What is the primary advantage of using 172-E15-103R021 over the original part?

A: The 172-E15-103R021 is an active product with ROHS3 compliance, whereas the original 172-E15-101R021 is obsolete and RoHS non-compliant. This ensures long-term availability and regulatory alignment for new designs and system updates.

Q: When should DAMO15P043 be selected instead of 172-E15-103R021?

A: Select DAMO15P043 when the application requires higher current capacity (7.5A), extended temperature operation (-55°C to 125°C), harsh environment protection, or 300V voltage rating. This part requires mechanical redesign due to free hanging mounting versus panel mount configuration.

Q: Are there compatibility concerns with different shell finishes (chromate, nickel, cadmium)?

A: Shell finish differences do not affect electrical compatibility or mating performance. Selection should be based on environmental exposure and corrosion resistance requirements. Nickel plating (172-E15-103R021) provides standard corrosion protection; chromate and cadmium finishes offer alternative environmental performance characteristics.

Q: What wire gauge compatibility should be verified when substituting these connectors?

A: The 172-E15-101R021 and 172-E15-103R021 both accept 20-26 AWG wire. The DAMO15P043 does not specify wire gauge in available documentation. Verify wire gauge compatibility with your specific termination requirements before implementation.

Q: Is the DAMO15P043 suitable for panel mount applications?

A: No. The DAMO15P043 is configured for free hanging (in-line) mounting, not panel mount. Mechanical redesign of the installation interface is required if this part is selected. For panel mount applications, use 172-E15-103R021.
