Engineering Selection Recommendations
All substitute parts listed maintain active product status and full compliance with RoHS and REACH regulations. Selection among equivalent parts should be based on the following engineering considerations:
Molex 67298 Series (0672983090, 0672983091, 0672984090, 0672984091): These connectors provide direct parametric equivalence with specified current rating of 1.5A and voltage rating of 30VDC. The series offers high inventory availability (2,317 to 25,281 pieces). Insulation color differentiation (Black or White) allows for design-specific selection. ROHS3 compliance status exceeds baseline RoHS requirements.
Würth Elektronik WR-COM Series (614008246521, 61400826021): These connectors include USB 2.0 specification compliance and extended operating temperature range (-40°C to 105°C). Mating cycle rating of 1500 cycles provides durability specification. The 614008246521 variant features single port configuration, while 61400826021 provides dual port configuration. Brass shielding material offers alternative to steel construction.
Mill-Max Manufacturing 896 Series (896-43-008-90-000000): This connector provides USB 2.0 compliance with stainless steel shielding material. Current rating of 1A is lower than Molex alternatives. Mating cycle rating of 1500 cycles is specified. Inventory availability of 7,483 pieces supports supply chain requirements.
Kycon KUSBX Series (KUSBX-AS2N-B, KUSBX-AS2N-B30, KUSBX-AS2N-W): These connectors feature extended operating temperature range (-40°C to 85°C) and 1500 mating cycle rating. Current rating of 1A is specified. Brass shielding material is used. High inventory availability (1,340 to 22,054 pieces) supports procurement needs. Insulation color options (Black or White) and voltage rating variations (30VAC standard, 30VAC for B30 variant) provide design flexibility.
Frequently Asked Questions (FAQ)
Q: What are the critical parameters that determine if a part can substitute for the TE Connectivity 1-1734084-1?
A: The following parameters must match for functional substitution: USB-A (USB TYPE-A) stacked connector type, 8-position contact configuration, receptacle gender, through-hole right-angle mounting, horizontal mounting feature, solder termination, board lock functionality, shielded construction, gold contact finish, UL94 V-0 flammability rating, and RoHS compliance status.
Q: Are there differences in electrical specifications between the main part and substitute parts?
A: Yes. The TE Connectivity 1-1734084-1 does not specify current rating or voltage rating in the provided parameters. Substitute parts provide specified electrical ratings: Molex parts specify 1.5A at 30VDC, Würth Elektronik parts specify 1.5A at 30VAC/30V, Mill-Max specifies 1A at 30VAC, and Kycon parts specify 1A at 30VAC. These specifications should be evaluated against application requirements.
Q: What is the significance of the port configuration differences?
A: Port configuration refers to the number of stacked USB connector positions on a single component. The main part and most substitute parts feature 2-port configuration. The Würth Elektronik 614008246521 variant features 1-port configuration. Port count affects physical board layout and should be verified against PCB design requirements.
Q: How do operating temperature ranges affect part selection?
A: The TE Connectivity 1-1734084-1 does not specify an operating temperature range. Substitute parts with specified temperature ranges include: Molex parts (0°C to 50°C), Würth Elektronik parts (-40°C to 105°C), and Kycon parts (-40°C to 85°C). Applications requiring operation outside standard temperature ranges should select parts with appropriate temperature specifications.
Q: What is the difference between RoHS and ROHS3 compliance?
A: The main part specifies RoHS Compliant status. Substitute parts specify ROHS3 Compliant status, which represents a more recent compliance standard. Both statuses indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 compliance is compatible with RoHS requirements.
Q: Are there packaging differences between the main part and substitutes?
A: The main part packaging is not specified in the provided parameters. Substitute parts are packaged in Tray format. Packaging format should be evaluated against procurement and assembly process requirements.
Q: What is the significance of insulation color variations?
A: Insulation color variations (Black or White) are available in Molex and Kycon product lines. These variations do not affect electrical or mechanical function and are typically selected based on design documentation or visual identification requirements.
Q: How do mating cycle ratings affect component selection?
A: The main part does not specify mating cycle rating. Substitute parts with specified mating cycles include: Würth Elektronik (1500 cycles), Mill-Max (1500 cycles), and Kycon (1500 cycles). Mating cycle rating indicates the number of connection/disconnection cycles the connector is rated to withstand. Applications requiring frequent mating should select parts with appropriate cycle ratings.
Q: What shielding material options are available?
A: The main part specifies steel shielding material. Substitute parts offer alternative shielding materials: Molex uses Brass and Steel (SUS 304), Würth Elektronik uses Brass, Mill-Max uses Steel and Stainless, and Kycon uses Brass. Shielding material selection affects electromagnetic interference (EMI) performance and should be evaluated against application requirements.
Q: Is the Moisture Sensitivity Level (MSL) rating the same across all parts?
A: Yes. The main part and all substitute parts specify MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.
