Substitute Part Grouping Explanation

Substitution for the Molex 0761650613 is determined by the following critical parameters: 144-position count, through-hole mounting, press-fit termination, male pin configuration, and PCB header application. The substitute parts are grouped into two categories based on electrical and mechanical compatibility:

Category 1: Direct Molex Series Substitute The Molex 0761651613 maintains identical electrical and mechanical specifications within the Impact 76165 series, differing only in packaging (Tray vs. standard) and product status (Active vs. Obsolete). This part is the primary direct replacement.

Category 2: TE Connectivity Z-PACK TinMan Series Substitutes The TE Connectivity parts (1934343-1, 1934344-1, 1934345-1, 1934346-1) provide functional equivalence with the following allowable parameter variations: pitch tolerance (0.075" vs. 0.053"), higher voltage rating (250V vs. 30V), extended temperature range (-65°C to 90°C vs. -55°C to 85°C), and current rating specification (0.5A). These parts maintain 144-position count, 9×16 configuration, through-hole mounting, press-fit termination, and male pin headers. All substitute parts are active products with current manufacturing status and full RoHS compliance.

Engineering Selection Recommendations

Primary Substitute: Molex 0761651613 For applications requiring exact electrical and mechanical compatibility with the original design, the Molex 0761651613 is the recommended substitute. This part maintains identical specifications within the Impact 76165 series and carries active product status with current manufacturing support. Both parts are ROHS3 compliant and suitable for direct replacement without PCB redesign.

Alternative Substitutes: TE Connectivity Z-PACK TinMan Series The TE Connectivity parts (1934343-1, 1934344-1, 1934345-1, 1934346-1) are suitable substitutes when design flexibility permits accommodation of the following parameter differences: increased pitch spacing (0.075" vs. 0.053"), higher voltage rating (250V vs. 30V), and extended operating temperature range (-65°C to 90°C vs. -55°C to 85°C). These parts are active products with established supply chains and full RoHS compliance. Selection among the four TE options depends on contact finish requirements: parts 1934344-1 and 1934346-1 feature gold plating (30.0µin), while 1934343-1 and 1934345-1 do not specify contact finish.

All substitute parts maintain the critical functional parameters: 144-position count, 9×16 configuration, through-hole mounting, press-fit termination, and male pin header design suitable for backplane connector applications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0761650613 be directly replaced with the Molex 0761651613? A: Yes. The 0761651613 is a direct substitute with identical electrical and mechanical specifications. The only differences are packaging format (Tray vs. standard) and product status (Active vs. Obsolete). No design changes are required.

Q: What are the main differences between the Molex Impact series and TE Connectivity Z-PACK TinMan series substitutes? A: The primary differences are pitch spacing (0.053" for Molex vs. 0.075" for TE), voltage rating (30V vs. 250V), and operating temperature range (-55°C to 85°C vs. -65°C to 90°C). Both series maintain 144-position count, 9×16 configuration, through-hole mounting, and press-fit termination. The larger pitch of the TE parts requires PCB layout modification.

Q: Are all substitute parts RoHS compliant? A: Yes. The Molex 0761651613 is ROHS3 compliant. The TE Connectivity parts are RoHS compliant, with 1934345-1 and 1934346-1 specifically rated ROHS3 compliant.

Q: Which TE Connectivity substitute should be selected if contact finish is critical? A: Parts 1934344-1 and 1934346-1 feature gold contact finish at 30.0µin thickness, matching the original specification. Parts 1934343-1 and 1934345-1 do not specify contact finish and should be selected only when contact finish is not a design requirement.

Q: Can the TE Connectivity substitutes be used in applications originally designed for the Molex 0761650613? A: TE Connectivity substitutes are functionally equivalent but require PCB redesign due to pitch spacing differences (0.075" vs. 0.053"). The larger pitch affects connector footprint and board layout. Applications with strict space constraints or existing PCB designs should use the Molex 0761651613 for direct compatibility.

Q: What is the current availability status of these parts? A: The Molex 0761650613 is obsolete but currently in stock (1106 pcs). The Molex 0761651613 is active with current inventory (908 pcs). All TE Connectivity substitutes are active products with established supply: 1934343-1 (1094 pcs), 1934344-1 (976 pcs), 1934345-1 (977 pcs), and 1934346-1 (1437 pcs).
