Substitute Part Grouping Explanation

Substitute parts for the 172-E15-111-021 are qualified based on the following core parameters that determine functional interchangeability:

Connector style: D-Sub
Connector type: Plug with male pins
Position count: 15 positions
Row configuration: 2 rows
Shell size and layout: Size 2 (DA, A)
Mounting type: Through-hole solder termination
Flange feature: Board-side mounting
Material flammability: UL94 V-0 rated

The identified substitute parts maintain these core parameters while allowing variation in secondary characteristics such as shell finish material, contact finish thickness, current rating, and operating temperature range, provided these variations remain within acceptable industrial standards for D-Sub connectors.

Engineering Selection Recommendations

All identified substitute parts maintain active product status and are functionally equivalent to the 172-E15-111-021 based on core D-Sub connector parameters. Selection among substitutes should be based on the following compliance and certification factors:

171-015-113R021 (NorComp Inc.) is the closest equivalent, maintaining identical operating temperature range (-50°C ~ 100°C) and ROHS3 compliance with matching shell finish and contact specifications.

09642227235 (HARTING) provides higher current rating (7.5A) and extended operating temperature range (-20°C ~ 125°C) with ROHS3 compliance, suitable for applications requiring enhanced thermal performance.

627-015-221-056 and 627-015-320-067 (Mercury United Electronics, Inc.) both offer ROHS3 compliance with board lock and shielding features, though with reduced current rating (3A per contact) and narrower operating temperature range (-55°C ~ 85°C).

M24308/24-2F (TE Connectivity) is a military-grade connector per MIL-DTL-24308 specification with extended operating temperature (-55°C ~ 125°C) and higher contact finish thickness (50.0µin). This part is RoHS non-compliant and REACH affected, requiring evaluation against regulatory requirements for the target application.

Frequently Asked Questions (FAQ)

Q: Can 171-015-113R021 be used as a direct replacement for 172-E15-111-021?

A: Yes. Both parts share identical core parameters: 15-position D-Sub plug, male pins, 2-row configuration, shell size 2 (DA, A), panel mount through-hole solder termination, board-side flange, UL94 V-0 rating, 5A current rating, gold contact finish, and -50°C ~ 100°C operating temperature. Both are ROHS3 compliant.

Q: What is the difference between the NorComp and Mercury substitute parts?

A: The primary differences are current rating and operating temperature range. Mercury parts (627-015-221-056 and 627-015-320-067) are rated for 3A per contact with -55°C ~ 85°C operating range, compared to 5A and -50°C ~ 100°C for NorComp parts. Mercury parts include board lock and shielding features.

Q: Is the M24308/24-2F suitable for commercial applications?

A: The M24308/24-2F is a military-specification connector (MIL-DTL-24308) with RoHS non-compliance and REACH-affected status. Use in commercial applications requires evaluation against applicable regulatory requirements and customer specifications.

Q: What packaging formats are available?

A: The main part (172-E15-111-021) is supplied in standard packaging. Substitute parts are available in Tray (171-015-113R021) and Bulk (09642227235, 627-015-221-056, 627-015-320-067, M24308/24-2F) packaging formats.

Q: Can parts with different current ratings be interchanged?

A: Parts with different current ratings (3A, 5A, or 7.5A) are mechanically and electrically compatible for connector mating. Selection should be based on circuit current requirements and thermal design considerations.

Q: Are all substitute parts ROHS3 compliant?

A: Five of the six substitute parts are ROHS3 compliant. The M24308/24-2F is RoHS non-compliant and should be selected only when military specifications or legacy system requirements mandate its use.
