Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWN-522-14-0021 is determined by the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm) — must match for mechanical compatibility
• Connector Type: Header — must be header configuration
• Contact Type: Male Pin — must maintain male pin contact
• Shrouding: Shrouded - 4 Wall — must provide equivalent shrouding
• Operating Temperature: -55°C ~ 125°C — must support full range
• Material Flammability Rating: UL94 V-0 — must meet or exceed rating
• RoHS Status: ROHS3 Compliant — must maintain compliance

The substitute part 09185167904 (HARTING SEK series) shares the core electrical and mechanical characteristics necessary for functional equivalence within rectangular connector applications, despite differences in position count, mounting orientation, and termination method.

Parameter Comparison

Engineering Selection Recommendations

Both the CWN-522-14-0021 and 09185167904 maintain active product status and full ROHS3 compliance with UL94 V-0 flammability certification. Selection between these parts must account for the following differences:

The CWN-522-14-0021 provides 14 positions with right-angle mounting and wire wrap termination, suitable for applications requiring angled board-to-cable connections with post-soldering wire attachment methods. The 09185167904 offers 16 positions with vertical mounting and solder termination, appropriate for applications requiring direct PCB soldering with increased position capacity.

Termination method compatibility with existing assembly processes is a primary selection criterion. Wire wrap termination requires dedicated equipment and post-insertion processing, while solder termination integrates with standard PCB assembly workflows. Position count differences necessitate circuit design verification to ensure the substitute configuration accommodates the target application.

Frequently Asked Questions (FAQ)

Q: Can the 09185167904 directly replace the CWN-522-14-0021 in existing designs?

A: Direct replacement requires design verification. While both parts share 0.100" (2.54mm) pitch, 2-row configuration, and shrouded 4-wall design, the 09185167904 differs in position count (16 vs. 14), mounting orientation (vertical vs. right-angle), and termination method (solder vs. wire wrap). Circuit layout and assembly process compatibility must be confirmed.

Q: What are the critical parameters for rectangular connector substitution?

A: Mating pitch, connector type, contact type, row configuration, row spacing, shrouding design, operating temperature range, and flammability rating are the primary parameters determining substitution eligibility. Differences in position count, mounting orientation, and termination method require application-specific evaluation.

Q: Does the substitute part maintain the same electrical performance?

A: Both parts operate across -55°C to 125°C, carry 1A current rating, feature gold-plated mating contacts, and meet UL94 V-0 flammability standards. Contact material and finish specifications differ (phosphor bronze vs. copper alloy; circular vs. square contact shape), which may affect contact resistance and insertion force characteristics in specific applications.

Q: Are there packaging or inventory considerations for the substitute part?

A: The CWN-522-14-0021 is supplied in standard packaging with 707 units in stock. The 09185167904 is supplied in tray packaging with 1160 units in stock. Packaging format may affect handling, storage, and integration into automated assembly processes.

Q: What termination method differences should be considered?

A: Wire wrap termination on the CWN-522-14-0021 requires post-insertion wire wrapping equipment and is typically used in prototype or low-volume applications. Solder termination on the 09185167904 integrates with standard PCB assembly and reflow processes, suitable for high-volume production environments.
