Molex 0761650817 72-Position Impact Backplane Connector Header

Part Overview

The Molex 0761650817 is a 72-position Impact series backplane connector header designed for through-hole PCB mounting. This component features male pins with press-fit termination and is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active product lines are necessary to ensure design continuity and supply chain reliability for new production runs and system upgrades.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0761650817 is determined by the following critical parameters: 72-position connector count, through-hole mounting, press-fit termination, male pin configuration, gold contact finish, and compliance certifications (UL94 V-0, ROHS3).

The substitute parts are grouped into two categories:

Direct Molex Series Equivalent: Part 0761651817 maintains identical electrical and mechanical specifications within the Impact 76165 series, differing only in packaging format (Tray vs. standard packaging) and product status (Active vs. Obsolete).

Cross-Manufacturer Alternatives: TE Connectivity AMP Connectors parts 1934300-1, 1934301-1, and 1934302-1 from the Z-PACK TinMan series provide functional equivalence with variations in pitch (0.075" vs. 0.053"), row/column configuration, connector style (High Speed vs. Impact), and connector type (Header vs. Plug). These alternatives maintain 72-position capacity, through-hole mounting, press-fit termination, gold contact finish, and compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: Part 0761651817 is the primary equivalent, maintaining identical specifications within the Molex Impact 76165 series. This part is currently active and available in production quantities, making it the preferred choice for designs requiring no PCB layout modifications.

For Cross-Manufacturer Substitution: TE Connectivity parts require design evaluation due to pitch differences (0.075" vs. 0.053"). Part 1934301-1 provides the closest mechanical compatibility with identical row/column configuration (9 × 8) and maintains all compliance certifications. Part 1934300-1 features a different row/column arrangement (9 × 3) and is suitable only for applications where connector footprint geometry can be accommodated. Part 1934302-1 is a plug configuration rather than a header and is applicable only in mating pair scenarios.

All substitute parts maintain UL94 V-0 flammability rating and ROHS3 compliance, ensuring regulatory continuity. The TE Connectivity alternatives provide enhanced voltage rating (250V vs. 30V) and extended operating temperature range (-65°C ~ 90°C vs. -55°C ~ 85°C), offering improved performance margins for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can 0761651817 be used as a direct replacement for 0761650817?

A: Yes. Both parts are Molex Impact 76165 series connectors with identical electrical and mechanical specifications: 72 positions, 0.053" pitch, 9 × 8 configuration, through-hole mounting, and press-fit termination. The primary difference is product status (Active vs. Obsolete) and packaging format (Tray vs. standard). No design changes are required.

Q: What are the key differences between Molex and TE Connectivity substitutes?

A: The primary differences are pitch (0.053" Molex vs. 0.075" TE Connectivity), row/column configuration, connector style (Impact vs. High Speed), and electrical ratings. TE Connectivity parts offer higher voltage rating (250V vs. 30V) and wider operating temperature range. PCB layout modifications are required for TE Connectivity substitution due to pitch differences.

Q: Can 1934300-1 replace 0761650817 directly?

A: No. While both are 72-position through-hole connectors with press-fit termination, 1934300-1 has a different row/column configuration (9 × 3 vs. 9 × 8) and larger pitch (0.075" vs. 0.053"). PCB footprint redesign is necessary. This part is suitable only for applications where the connector geometry can be accommodated.

Q: Is 1934302-1 compatible with designs using 0761650817?

A: No. Part 1934302-1 is a plug configuration, not a header. It is designed to mate with a header connector and cannot directly replace a header in existing designs. Use only in applications requiring a mating pair connector.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All listed substitutes maintain UL94 V-0 flammability rating and ROHS3 compliance, ensuring regulatory continuity with the original part. TE Connectivity parts carry REACH Vendor Undefined status, which should be verified against specific application requirements.

Q: What packaging formats are available for these parts?

A: Molex 0761650817 is supplied in standard packaging (927 pcs in stock). Molex 0761651817 is supplied in Tray format (1027 pcs in stock). TE Connectivity parts 1934300-1, 1934301-1, and 1934302-1 are supplied in Tube format with inventory levels of 732, 855, and 3458 pcs respectively.
