Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 1934300-1 or 1934302-1 directly replace the Molex 0761651815 in existing designs?

A: Direct replacement requires PCB layout verification. The pitch difference (0.053" vs. 0.075") and column configuration changes (8 vs. 3 columns for 1934300-1) necessitate mechanical and electrical redesign. The 1934302-1 maintains the 8-column layout but still requires pitch accommodation on the PCB.

Q: What is the primary difference between the two TE Connectivity substitutes?

A: The 1934300-1 is a Header configuration with 9 rows by 3 columns, while the 1934302-1 is a Plug configuration with 9 rows by 8 columns. The 1934302-1 more closely matches the original part's column arrangement.

Q: Are the substitute parts suitable for the same voltage and temperature applications?

A: The substitutes support higher voltage (250V vs. 30V) and wider temperature range (-65°C to 90°C vs. -55°C to 85°C), making them suitable for more demanding applications. Applications within the original part's specifications remain compatible.

Q: What packaging differences exist between these parts?

A: The Molex 0761651815 is supplied in Tray packaging, while both TE Connectivity substitutes are supplied in Tube packaging. Procurement and handling procedures may differ accordingly.

Q: Do all parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, UL94 V-0 rated, and carry MSL 1 moisture sensitivity level. Regulatory and environmental requirements are equivalent across all options.

Q: What is the significance of the 0.5A current rating in the substitute parts?

A: The TE Connectivity substitutes specify 0.5A per contact, providing defined current-carrying capacity for power distribution applications. The original Molex part does not specify a current rating, requiring application-specific verification.
