Substitute Part Grouping Explanation

Substitution for the Molex 0761650626 is determined by the following critical parameters:

Primary Compatibility Criteria:

Number of positions: 144
Connector type: Header, male pins
Mounting type: Through hole
Termination method: Press-fit
Configuration: 9 rows × 16 columns
Contact layout: 48 differential pairs

Substitute parts are grouped into two categories:

Direct Molex Series Substitute (0761651626): Identical electrical and mechanical specifications with active product status and improved packaging (Tray). This part maintains the same 0.053" (1.35mm) pitch and Impact 76165 series designation.
Cross-Manufacturer TE Connectivity Substitutes (1934343-1, 1934344-1, 1934345-1, 1934346-1): These parts share the same 144-position count, 9×16 configuration, through-hole mounting, and press-fit termination. However, they operate at a different pitch (0.075" / 1.90mm) and belong to the Z-PACK TinMan series. These substitutes are suitable only when PCB layout and mating connector specifications accommodate the larger pitch.

Engineering Selection Recommendations

For Direct Replacement (Same Pitch – 0.053" / 1.35mm):

Select Molex 0761651626 when PCB layout and mating connectors are designed for the 0.053" pitch. This part maintains identical electrical and mechanical specifications to the obsolete 0761650626 while offering active product status, ensuring long-term availability and supply chain stability. Both parts are ROHS3 compliant and rated for -55°C to 85°C operation at 30V.

For Cross-Manufacturer Substitution (Larger Pitch – 0.075" / 1.90mm):

TE Connectivity Z-PACK TinMan series parts (1934343-1, 1934344-1, 1934345-1, 1934346-1) are suitable only when the PCB layout and mating connector specifications are redesigned to accommodate the 0.075" pitch. These parts offer extended operating temperature range (-65°C to 90°C), higher voltage rating (250V), and specified current rating (0.5A). Selection among these four TE parts depends on contact finish requirements and specific application needs:

1934343-1 and 1934345-1: Standard contact finish (not specified)
1934344-1 and 1934346-1: Gold-plated contacts (30.0µin thickness)

All TE Connectivity substitutes are active products with RoHS compliance and UL94 V-0 flammability rating.

Frequently Asked Questions (FAQ)

Q: Can I use the TE Connectivity parts as direct drop-in replacements for the Molex 0761650626?

A: No. While both the Molex 0761650626 and TE Connectivity Z-PACK TinMan parts share the same 144-position count and 9×16 configuration, they operate at different pitches (0.053" vs. 0.075"). Direct substitution requires PCB layout and mating connector redesign. The Molex 0761651626 is the only true direct replacement.

Q: What is the key difference between the Molex 0761650626 and 0761651626?

A: Both parts are electrically and mechanically identical, belonging to the same Impact 76165 series with 0.053" pitch. The primary difference is product status: 0761650626 is obsolete, while 0761651626 is active. Additionally, 0761651626 is supplied in Tray packaging, improving handling and storage compared to the main part.

Q: Are all substitute parts RoHS compliant?

A: Yes. The Molex 0761651626 is ROHS3 compliant. The TE Connectivity parts (1934343-1, 1934345-1, 1934346-1) are ROHS3 compliant, while 1934344-1 is RoHS compliant. All parts meet environmental compliance requirements.

Q: What are the packaging differences among substitute parts?

A: Molex 0761651626 is supplied in Tray packaging. All TE Connectivity substitutes (1934343-1, 1934344-1, 1934345-1, 1934346-1) are supplied in Tube packaging. Packaging selection may affect handling, storage, and integration into assembly processes.

Q: Which TE Connectivity part should I select if contact finish is critical?

A: If gold-plated contacts are required, select either 1934344-1 or 1934346-1, both featuring 30.0µin (0.76µm) gold plating. Parts 1934343-1 and 1934345-1 do not specify contact finish and may not be suitable for applications requiring corrosion resistance or specific electrical properties associated with gold plating.

Q: Can I mix parts from different manufacturers in the same design?

A: Mixing Molex and TE Connectivity connectors in the same design is not recommended without careful evaluation of mating connector compatibility, pitch alignment, and mechanical fit. Standardize on a single manufacturer and series for consistency and reliability.
