Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 172-E09-112-021 are qualified based on the following critical parameters that must match or exceed the original specification:

Mandatory Matching Parameters:

• Connector style: D-Sub
• Connector type: Plug, Male Pins
• Number of positions: 9
• Number of rows: 2
• Shell size and layout: 1 (DE, E)
• Mounting type: Panel Mount, Through Hole
• Termination method: Solder
• Flange feature: Board Side (4-40)
• Contact type: Signal
• Material flammability rating: UL94 V-0

Allowable Variations:

• Shell material finish (tin plated vs. nickel plated)
• Dielectric material composition (PBT glass-filled vs. polyamide or polyester thermoplastic)
• Contact material specification
• Operating temperature range (may be narrower or equivalent)
• Current rating per contact (may be equal or higher)
• Product status (active substitutes preferred for obsolete parts)
• RoHS compliance status

The following parts meet these substitution criteria:

Direct Manufacturer Substitute (NorComp Inc.):

• 172-E09-113R021

Cross-Manufacturer Substitutes (Mercury United Electronics, Inc.):

• 627-009-220-047
• 627-009-221-048
• 627-009-620-046

Engineering Selection Recommendations

172-E09-113R021 (NorComp Inc.)

This direct manufacturer substitute from NorComp Inc. is the primary recommended replacement for the obsolete 172-E09-112-021. It maintains identical electrical and mechanical specifications, including 5A current rating and -50°C to 100°C operating temperature range. The part is currently active in production and carries ROHS3 compliance, addressing regulatory requirements that the original part does not meet. The dielectric material differs (polyamide vs. PBT glass-filled), but both materials satisfy UL94 V-0 flammability requirements. This substitute is available in tray packaging with 900 units in stock.

627-009-221-048 (Mercury United Electronics, Inc.)

This cross-manufacturer substitute provides functional equivalence with the original part, maintaining the 5A current rating and matching the -55°C to 85°C operating temperature range (which encompasses the original -50°C to 100°C specification at the lower end). The part is active and ROHS3 compliant. It features shielding and board lock features not present in the original specification. Available in bulk packaging with 1022 units in stock.

627-009-220-047 and 627-009-620-046 (Mercury United Electronics, Inc.)

These Mercury United Electronics substitutes are functionally compatible but carry a reduced current rating of 3A per contact compared to the original 5A specification. Both parts are active, ROHS3 compliant, and feature board lock and shielding. These options are suitable only for applications where the 3A per contact rating is acceptable. Operating temperature range is -55°C to 85°C.

Frequently Asked Questions (FAQ)

Q: Can I use 627-009-220-047 or 627-009-620-046 as direct replacements for the 172-E09-112-021?

A: These parts are mechanically and electrically compatible in terms of connector geometry, pin configuration, and termination method. However, they are rated for 3A per contact versus the original 5A rating. Use these substitutes only if your application current requirements do not exceed 3A per contact.

Q: What is the difference between the NorComp 172-E09-113R021 and the Mercury United 627-009-221-048?

A: Both parts maintain the 5A current rating and are functionally equivalent. The primary differences are manufacturer, dielectric material composition, and packaging format. The NorComp part is available in tray packaging, while the Mercury part is available in bulk. Both are ROHS3 compliant and active in production.

Q: Does the operating temperature range difference matter?

A: The original 172-E09-112-021 operates from -50°C to 100°C. The Mercury United substitutes operate from -55°C to 85°C. The lower temperature limit is better (-55°C vs. -50°C), but the upper limit is reduced (85°C vs. 100°C). Verify that your application does not require operation above 85°C before selecting a Mercury United substitute.

Q: Why is the original part obsolete?

A: The 172-E09-112-021 is listed as obsolete by the manufacturer. The active substitute 172-E09-113R021 from the same manufacturer is the recommended replacement for continued supply and support.

Q: Are all substitute parts RoHS compliant?

A: The original 172-E09-112-021 is RoHS non-compliant. All listed substitutes (172-E09-113R021, 627-009-220-047, 627-009-221-048, and 627-009-620-046) are ROHS3 compliant, meeting current regulatory requirements for new designs and applications subject to RoHS directives.

Q: What packaging options are available?

A: The 172-E09-113R021 is available in tray packaging. The Mercury United 627-009-221-048 is available in bulk packaging. The 627-009-220-047 and 627-009-620-046 are available in tray packaging. Select packaging based on your procurement and assembly requirements.
