Molex 0761650816 72-Position Impact Backplane Connector Header

Part Overview

The Molex 0761650816 is a 72-position Impact series backplane connector header designed for through-hole PCB mounting. This connector 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.

Substitute Part Grouping Explanation

Substitution for the Molex 0761650816 is determined by the following critical parameters: 72-position connector count, through-hole mounting, press-fit termination, male pin configuration, gold contact finish, UL94 V-0 flammability rating, and ROHS3 compliance.

The substitute parts are grouped into two categories:

Direct Equivalent (Same Series): The Molex 0761651816 maintains identical electrical and mechanical specifications as the original part, differing only in packaging (Tray versus standard packaging) and product status (Active versus Obsolete). This part is the primary direct substitute.

Cross-Manufacturer Alternatives (TE Connectivity Z-PACK TinMan Series): Parts 1934300-1, 1934301-1, and 1934302-1 from TE Connectivity provide functional substitution with the following parameter variations: increased pitch (0.075" versus 0.053"), modified row/column configuration, higher voltage rating (250V versus 30V), extended operating temperature range (-65°C to 90°C versus -55°C to 85°C), and specified current rating (0.5A). Part 1934302-1 differs in connector type (Plug versus Header). These alternatives maintain 72-position capacity, through-hole mounting, press-fit termination, gold contact finish, UL94 V-0 rating, and ROHS3 compliance.

Engineering Selection Recommendations

For Direct Replacement: The Molex 0761651816 is the primary substitute for the 0761650816. Both parts maintain identical electrical and mechanical specifications within the Impact 76165 series. The 0761651816 is currently in active production status with higher inventory availability (1022 units), ensuring supply chain continuity. This part requires no design modification and is suitable for direct substitution in existing applications.

For Cross-Manufacturer Substitution: TE Connectivity Z-PACK TinMan series parts (1934300-1, 1934301-1, 1934302-1) are suitable when design flexibility permits accommodation of parameter variations. These parts offer enhanced electrical performance (250V rating versus 30V, 0.5A current rating) and extended operating temperature range (-65°C to 90°C). The increased pitch (0.075" versus 0.053") requires PCB layout modification. Part 1934302-1 (Plug configuration) is applicable only when the mating interface requires a plug rather than header connector.

All substitute parts maintain ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity classification, ensuring regulatory and environmental compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0761651816 be used as a direct replacement for the 0761650816?

A: Yes. Both parts are from the same Impact 76165 series and share identical electrical and mechanical parameters: 72 positions, 0.053" pitch, 9 rows by 8 columns, through-hole press-fit termination, gold contact finish, 30V voltage rating, and -55°C to 85°C operating temperature. The only difference is packaging type and product status. No design changes are required.

Q: What are the key differences between the Molex Impact series and TE Connectivity Z-PACK TinMan series?

A: The primary differences are pitch (0.053" versus 0.075"), voltage rating (30V versus 250V), current rating (unspecified versus 0.5A), and operating temperature range (-55°C to 85°C versus -65°C to 90°C). The TE Connectivity parts offer higher electrical performance specifications. Cross-manufacturer substitution requires PCB layout modification due to pitch change.

Q: Is the TE Connectivity 1934302-1 compatible with applications designed for the Molex 0761650816?

A: The 1934302-1 is a Plug connector, whereas the Molex 0761650816 is a Header connector. These are complementary connector types designed to mate with each other. Substitution is applicable only if the application interface is designed to accept a plug configuration rather than a header.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The Molex 0761651816 and all TE Connectivity alternatives (1934300-1, 1934301-1, 1934302-1) are ROHS3 compliant with UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification.

Q: What packaging options are available for these connectors?

A: The Molex 0761650816 is supplied in standard packaging. The Molex 0761651816 is supplied in Tray packaging. TE Connectivity parts (1934300-1, 1934301-1, 1934302-1) are supplied in Tube packaging. Packaging selection should be coordinated with procurement and assembly requirements.
