Engineering Selection Recommendations

Direct Molex Equivalent (Recommended for Pin-Compatible Replacement):

The Molex 0761551628 is the direct functional equivalent of the obsolete 0761550628. Both parts maintain identical electrical and mechanical specifications, including 0.053" (1.35mm) pitch, 192-position configuration, and Impact series design. The 0761551628 carries Active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. This part is suitable for direct substitution in existing designs without PCB layout modifications.

TE Connectivity Z-PACK TinMan Alternatives (For Enhanced Performance Requirements):

The TE Connectivity parts (1934315-1, 1934316-1, 1934317-1, 1934318-1) represent functionally compatible alternatives with modified specifications. These High Speed connectors feature 0.075" (1.90mm) pitch, extended operating temperature range (-65°C ~ 90°C), elevated voltage rating (250V), and specified current rating (0.5A). These parts require PCB layout redesign due to pitch modification but offer enhanced electrical performance and active product status. Selection among these four variants depends on packaging requirements: Tube packaging for 1934315-1, 1934317-1, and 1934318-1; Bulk packaging for 1934316-1.

Product Status Consideration:

The original 0761550628 is obsolete. The 0761551628 (Molex) and all TE Connectivity alternatives carry Active status, ensuring continued manufacturing support and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0761551628 be used as a direct replacement for the 0761550628?

A: Yes. Both parts are Molex Impact series connectors with identical 192-position configuration, 0.053" (1.35mm) pitch, through-hole mounting, and press-fit termination. No PCB modifications are required. The 0761551628 is the active production equivalent.

Q: What is the primary difference between Molex Impact and TE Connectivity Z-PACK TinMan connectors?

A: The primary difference is pitch specification. Molex Impact parts use 0.053" (1.35mm) pitch, while TE Connectivity Z-PACK TinMan parts use 0.075" (1.90mm) pitch. This difference requires PCB layout redesign. TE Connectivity alternatives also provide higher voltage rating (250V vs. 30V) and specified current rating (0.5A).

Q: Do the TE Connectivity alternatives require PCB redesign?

A: Yes. The 0.075" (1.90mm) pitch of TE Connectivity parts differs from the original 0.053" (1.35mm) pitch. PCB hole spacing and connector footprint must be modified to accommodate the larger pitch.

Q: Are all substitute parts RoHS compliant?

A: Yes. The Molex 0761551628 is ROHS3 compliant. TE Connectivity parts 1934315-1, 1934317-1, and 1934318-1 are ROHS3 compliant; part 1934316-1 is RoHS compliant. All meet regulatory requirements for restricted substance elimination.

Q: What packaging options are available for the substitute parts?

A: Molex 0761551628 is supplied in Tray packaging. TE Connectivity alternatives are available in Tube packaging (1934315-1, 1934317-1, 1934318-1) or Bulk packaging (1934316-1). Packaging selection depends on production volume and handling requirements.

Q: Which substitute part offers the highest inventory availability?

A: TE Connectivity 1934318-1 has the highest reported inventory at 2,240 pieces. Molex 0761551628 has 755 pieces available. Inventory levels should be confirmed with the supplier for current availability.

Q: Are the operating temperature ranges compatible with the original specification?

A: The Molex 0761551628 maintains the original -55°C ~ 85°C range. TE Connectivity alternatives extend this to -65°C ~ 90°C, providing broader environmental operating capability.
