Substitution Categories:

Direct Molex Equivalent (Same Series):

Molex 0761557606 maintains identical electrical and mechanical specifications to the main part, with the primary difference being active product status and tray packaging. This part is the direct successor within the Impact 76155 series.

Cross-Manufacturer Alternatives (TE Connectivity Z-PACK TinMan Series):

TE Connectivity 1934315-1, 1934316-1, 1934317-1, and 1934318-1 provide functional equivalence with the following parameter variations: increased pitch (0.075" / 1.90mm), higher voltage rating (250V vs. 30V), expanded operating temperature range (-65°C to 90°C vs. -55°C to 85°C), and specified current rating (0.5A). These parts maintain 192 positions, through-hole mounting, press-fit termination, and gold contact finish.

Engineering Selection Recommendations

For Direct Replacement (Preferred): Select Molex 0761557606 when system specifications require identical electrical and mechanical parameters. This part maintains the same pitch (0.053"), voltage rating (30V), and operating temperature range as the obsolete 0761556606. Active product status and established supply chain availability support long-term design continuity.

For Enhanced Performance Requirements: TE Connectivity 1934315-1, 1934316-1, 1934317-1, and 1934318-1 are suitable when system design permits accommodation of the increased pitch (0.075") and can benefit from higher voltage rating (250V) and expanded operating temperature range (-65°C to 90°C). These parts are active products with established manufacturing support. Selection among these four TE variants depends on packaging requirements: 1934315-1 and 1934317-1 are supplied in tubes, while 1934316-1 is supplied in bulk. 1934318-1 is supplied in tubes with the highest inventory availability (2240 pcs).

All substitute parts maintain UL94 V-0 flammability compliance, gold contact finish, and RoHS compliance, ensuring regulatory and environmental requirement alignment.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity parts directly replace the Molex 0761556606 without PCB redesign?

A: TE Connectivity parts feature a larger pitch (0.075" vs. 0.053"), requiring PCB footprint modification. Direct mechanical substitution is not possible without redesign. Molex 0761557606 provides true pin-for-pin compatibility.

Q: What is the primary reason for substituting the obsolete Molex 0761556606?

A: The part is classified as obsolete, limiting future availability and manufacturing support. Molex 0761557606 provides identical functionality with active product status.

Q: Are all substitute parts RoHS compliant?

A: Yes. Molex 0761557606 is ROHS3 compliant. TE Connectivity parts are either ROHS3 or RoHS compliant, meeting regulatory requirements.

Q: What are the packaging differences among TE Connectivity alternatives?

A: 1934315-1 and 1934317-1 are supplied in tubes; 1934316-1 is supplied in bulk; 1934318-1 is supplied in tubes. Selection depends on procurement and handling requirements.

Q: Do the TE Connectivity parts support the same contact layout as the Molex original?

A: Both maintain 192 positions in a 12×16 configuration with through-hole, press-fit termination and gold contact finish. The TE parts do not specify differential pair configuration in the provided data.
