Substitute Part Grouping Explanation

Substitution for the Molex 0761650825 is determined by the following critical parameters: number of positions (72), connector type (header with male pins), mounting method (through-hole), termination style (press-fit), contact finish (gold), and material compliance (UL94 V-0, ROHS3).

The substitute parts are grouped into two categories:

Direct Molex Series Equivalent: Part 0761651825 maintains identical electrical and mechanical specifications as the original 0761650825, differing only in packaging (tray versus standard packaging) and product status (active versus obsolete). This part is the primary direct substitute within the Impact 76165 series.

Cross-Manufacturer Alternatives: Parts 1934300-1, 1934301-1, and 1934302-1 from TE Connectivity AMP Connectors represent functional alternatives from a different manufacturer. These parts share the 72-position count, through-hole mounting, press-fit termination, gold contact finish, and compliance certifications. However, they differ in pitch spacing (0.075" versus 0.053"), array configuration (3 or 8 columns versus 8 columns), connector style (High Speed versus Impact), and electrical ratings (0.5A current rating and 250V voltage rating versus unspecified current and 30V voltage rating). Part 1934302-1 is a plug configuration rather than a header.

Engineering Selection Recommendations

For Direct Replacement: Part 0761651825 is the recommended substitute for the obsolete Molex 0761650825. Both parts maintain identical electrical and mechanical specifications, including pitch, array configuration, and operating parameters. The primary difference is product status; 0761651825 is active and currently in production, ensuring long-term availability and supply chain continuity. This part is suitable for direct PCB layout compatibility without design modification.

For Cross-Manufacturer Substitution: TE Connectivity parts 1934300-1, 1934301-1, and 1934302-1 are functional alternatives when direct Molex equivalents are unavailable. These parts share core compliance certifications (UL94 V-0, ROHS3) and moisture sensitivity ratings. However, substitution requires PCB layout redesign due to pitch spacing differences (0.075" versus 0.053") and array configuration variations. Part 1934301-1 maintains the 9×8 array configuration and is the closest mechanical match among TE Connectivity options. Part 1934302-1 is a plug configuration and is not suitable for header applications. The higher voltage rating (250V) and specified current rating (0.5A) of TE Connectivity parts provide enhanced electrical performance margins compared to the original specification.

Frequently Asked Questions (FAQ)

Q: Can 0761651825 be used as a direct replacement for 0761650825? A: Yes. Both parts are Molex Impact 76165 series connectors with identical 72-position, 0.053" pitch, 9×8 array configuration. The only difference is packaging and product status. 0761651825 is active and recommended for new designs and ongoing support.

Q: What are the key differences between Molex and TE Connectivity substitutes? A: Molex 0761651825 maintains identical pitch and array configuration. TE Connectivity parts use 0.075" pitch spacing and differ in array configuration (1934300-1 uses 9×3, while 1934301-1 and 1934302-1 use 9×8). TE Connectivity parts also provide higher voltage (250V) and specified current ratings (0.5A).

Q: Can TE Connectivity parts be used without PCB redesign? A: No. The 0.075" pitch of TE Connectivity parts is incompatible with PCB layouts designed for the 0.053" pitch of the original Molex connector. PCB footprint redesign is required.

Q: Is part 1934302-1 suitable for header applications? A: No. Part 1934302-1 is a plug configuration, not a header. It is not suitable for applications requiring a header connector.

Q: Do all substitute parts meet the same compliance standards? A: Yes. All substitute parts are ROHS3 compliant, UL94 V-0 rated, and have MSL 1 (Unlimited) moisture sensitivity levels, matching the original part's compliance profile.

Q: What is the inventory status of substitute parts? A: Molex 0761651825 has 998 units in stock. TE Connectivity 1934300-1 has 732 units, 1934301-1 has 855 units, and 1934302-1 has 3458 units available.
