Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 171-009-102-021 are identified based on functional equivalence within the D-Sub connector category. The critical parameters determining substitution eligibility are:

• Connector style: D-Sub
• Connector type: Plug with male pins
• Number of positions: 9
• Number of rows: 2
• Shell size and layout: 1 (DE, E)
• Termination method: Solder cup
• Contact type: Signal

Two substitute parts meet these core criteria:

171-009-103L021 (NorComp Inc., Series 171): Direct manufacturer alternative with identical core specifications, supplied in tray packaging with 3,571 units in stock.

627-009-222-042 (Mercury United Electronics, Inc., Series 627): Cross-manufacturer alternative with matching connector geometry and termination, supplied in bulk packaging with 1,025 units in stock. This part operates with different mounting configuration (free hanging/in-line) and exhibits variations in current rating and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

171-009-103L021 is the primary substitute for 171-009-102-021. Both parts are manufactured by NorComp Inc. within Series 171, share identical connector specifications, and maintain equivalent compliance certifications (ROHS3, REACH Unaffected, EAR99). The 171-009-103L021 offers higher current rating (5A) and extended operating temperature range (-50°C to 100°C), with greater inventory availability (3,571 units). Packaging differs (tray versus unspecified), which may affect procurement and handling procedures.

627-009-222-042 serves as a secondary cross-manufacturer substitute. While maintaining core D-Sub geometry and electrical characteristics, this part differs in mounting configuration (free hanging/in-line versus panel mount) and exhibits reduced current rating (3A per contact) and narrower operating temperature range (-55°C to 85°C). Selection of this part requires confirmation that the application tolerates in-line mounting and the specified electrical and thermal parameters.

All three parts maintain active product status and full regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can 171-009-103L021 directly replace 171-009-102-021 in existing designs?

A: Yes. Both parts share identical connector specifications, including shell size, pin count, termination method, and contact configuration. The primary difference is packaging format (tray versus unspecified). Electrical and mechanical compatibility is maintained.

Q: What are the key differences between 171-009-103L021 and 627-009-222-042?

A: The primary differences are manufacturer (NorComp Inc. versus Mercury United Electronics, Inc.), mounting type (panel mount versus free hanging/in-line), current rating (5A versus 3A per contact), and operating temperature range (-50°C to 100°C versus -55°C to 85°C). Both maintain identical shell size, pin count, and termination method.

Q: Is 627-009-222-042 suitable for panel mount applications?

A: No. The 627-009-222-042 is configured for free hanging (in-line) mounting, not panel mount. Applications requiring panel mount should use 171-009-102-021 or 171-009-103L021.

Q: Do all three parts meet the same regulatory requirements?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. All maintain UL94 V-0 material flammability rating.

Q: What is the inventory status for each part?

A: 171-009-102-021 has 1,070 units in stock; 171-009-103L021 has 3,571 units in stock; 627-009-222-042 has 1,025 units in stock. All are classified as new original inventory.

Q: Are there packaging considerations when selecting a substitute?

A: Yes. 171-009-103L021 is supplied in tray packaging, while 627-009-222-042 is supplied in bulk packaging. Packaging format may affect handling, storage, and procurement workflows. Verify packaging compatibility with receiving and assembly procedures.
