Engineering Selection Recommendations

Primary Substitute: NorComp 171-009-213R021

The 171-009-213R021 is the direct equivalent from NorComp, maintaining identical electrical and mechanical specifications with the main part. Both connectors feature identical operating temperature range (-50°C to 100°C), current rating (5A), dielectric material (PA9T), and contact finish (gold flash). The only difference is packaging format (tray versus standard). This part is recommended for applications requiring exact specification matching and NorComp brand continuity.

Secondary Substitutes: HARTING 09661116501, 09661117502, 09661156501, 09661516512

HARTING D-Sub receptacles provide functional equivalence with enhanced electrical performance. These parts exceed the main part's current rating (6.5A versus 5A) and operating temperature range (-55°C to 125°C versus -50°C to 100°C). All substitute candidates maintain UL94 V-0 flammability rating and ROHS3 compliance. Dielectric materials vary between PBT and PCT formulations, both meeting thermoplastic requirements for D-Sub applications.

Flange Feature Considerations

Mounting compatibility depends on flange configuration. The main part specifies board-side flange (4-40). HARTING substitutes offer either housing/shell flange (M3) or housing/shell flange (4-40). Selection must align with PCB mounting hole specifications.

Product Status Verification

All recommended substitutes maintain active product status. Part 09661156502 (HARTING) is marked obsolete and is not recommended for new designs.

Frequently Asked Questions (FAQ)

Q: Can HARTING 09661117502 directly replace NorComp 171-009-212-021?

A: Yes, for applications within the main part's operating specifications. The HARTING part exceeds performance requirements with 6.5A current rating and -55°C to 125°C temperature range. Verify flange mounting compatibility (4-40 housing/shell flange on HARTING versus 4-40 board-side flange on NorComp).

Q: What is the difference between 09661116501 and 09661117502?

A: Both are HARTING 9-position D-Sub receptacles with identical electrical specifications. The primary difference is flange feature: 09661116501 uses M3 housing/shell flange, while 09661117502 uses 4-40 housing/shell flange. Select based on PCB mounting hole configuration.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitutes, including the direct NorComp equivalent 171-009-213R021 and all HARTING alternatives, maintain ROHS3 compliance and are suitable for applications requiring RoHS certification.

Q: What is the significance of contact finish differences?

A: The main part specifies gold-flash contact finish. NorComp 171-009-213R021 maintains this specification. HARTING parts 09661156501 and 09661157502 include gold contact finish; others do not specify finish. Gold plating enhances corrosion resistance and contact reliability in signal transmission applications.

Q: Can I use 09661156502 as a substitute?

A: No. This HARTING part is marked obsolete and should not be selected for new designs or long-term applications.

Q: How does dielectric material affect substitution?

A: The main part uses polyamide (PA9T). Substitute parts employ PBT or PCT dielectric materials. All materials meet UL94 V-0 flammability requirements and are thermoplastically equivalent for D-Sub connector applications. Material selection does not affect electrical compatibility.

Q: What packaging options are available?

A: NorComp 171-009-212-021 is supplied in standard packaging (737 units in stock). The direct substitute 171-009-213R021 is supplied in tray packaging (673 units). HARTING substitutes are available in bulk or tray formats depending on part number suffix.
