Compliance Considerations:
All recommended substitute parts maintain UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity level. The TE Connectivity 5787685-1 carries REACH affected status, while HARTING and NorComp alternatives carry REACH unaffected status. Selection should account for supply chain compliance requirements specific to the application region.
Frequently Asked Questions (FAQ)
Q: Can the TE Connectivity 5787685-1 directly replace the 3-338316-2 in existing designs?
A: Yes. The 5787685-1 maintains identical electrical and mechanical specifications including connector type, position count, shell size, flange configuration, and termination method. The primary difference is product status: the 3-338316-2 is obsolete while the 5787685-1 is active. Both connectors are from TE Connectivity's AMPLIMITE series and are fully compatible.
Q: What are the key differences between TE Connectivity and HARTING 37-position D-Sub receptacles?
A: Both manufacturers provide connectors that satisfy all mandatory parameters for substitution. HARTING parts offer higher current ratings (6.5A versus 6A) and extended operating temperature range (-55°C ~ 125°C versus -55°C ~ 105°C). HARTING parts carry REACH unaffected status, while TE Connectivity parts carry REACH affected status. Contact material differs: TE Connectivity uses Phosphor Bronze while HARTING uses Copper Alloy. Dielectric materials vary between manufacturers but all meet UL94 V-0 flammability requirements.
Q: Are NorComp 37-position D-Sub receptacles suitable substitutes?
A: NorComp parts 191-037-213L001 and 191-037-213L571 are active alternatives that satisfy all mandatory parameters. However, these connectors feature panel mount capability in addition to through-hole mounting, which may introduce dimensional differences. NorComp parts 172-037-212R001 and 172-037-212R011 are obsolete and should not be selected for new designs. Current ratings for NorComp parts are 5A, which is lower than the 6A requirement of the main part.
Q: What is the significance of the flange feature designation?
A: The flange feature "Mating Side, Female Screwlock (4-40)" specifies the mechanical interface for connector mating. This designation indicates that the screwlock mechanism is located on the mating side of the connector and uses 4-40 threaded fasteners. All recommended substitute parts maintain this identical flange configuration, ensuring mechanical compatibility with existing mating connectors and cable assemblies.
Q: How do packaging options affect part selection?
A: Packaging options (tube, tray, bulk) do not affect electrical or mechanical compatibility. The TE Connectivity 5787685-1 is supplied in tube packaging, while HARTING parts are available in tray or bulk packaging. NorComp parts are supplied in tray packaging. Packaging selection should be based on procurement volume requirements and inventory management practices rather than technical compatibility.
Q: What compliance certifications should be verified for critical applications?
A: All recommended substitute parts carry UL94 V-0 flammability certification and MSL 1 (Unlimited) moisture sensitivity level. RoHS compliance is maintained across all alternatives. REACH status differs: TE Connectivity parts carry REACH affected status while HARTING and NorComp parts carry REACH unaffected status. Applications subject to regional compliance requirements should verify REACH status against specific regulatory obligations.
Q: Can parts with different dielectric materials be substituted?
A: Yes. The main part 3-338316-2 specifies Polyester, Glass Filled dielectric material. Substitute parts utilize Polybutylene Terephthalate (PBT), Polycyclohexylenedimethylene Terephthalate (PCT), or Polyester materials. All dielectric materials meet UL94 V-0 flammability requirements and maintain electrical performance within the specified operating temperature range. Material selection does not affect connector compatibility.
Q: What is the impact of operating temperature range differences?
A: The main part 3-338316-2 operates from -55°C to 105°C. HARTING and NorComp 191-series parts extend this range to -55°C to 125°C, providing additional thermal margin. NorComp 172-series parts operate from -50°C to 100°C, which does not fully encompass the lower temperature limit of the main part. For applications requiring operation at -55°C, NorComp 172-series parts are not suitable.
Q: Are there any restrictions on mixing substitute parts in the same assembly?
A: All recommended substitute parts maintain identical connector style, position count, shell size, and flange configuration. Mixing different manufacturers' parts in the same assembly is permissible from an electrical and mechanical standpoint. However, procurement and quality assurance practices should account for potential variations in contact material, dielectric composition, and manufacturing tolerances between manufacturers.
