Engineering Selection Recommendations

All substitute parts maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. The TE Connectivity Z-PACK TinMan series (1934303-1, 1934304-1, 1934305-1, 1934306-1) provides enhanced voltage rating (250V vs. 30V) and extended operating temperature range (-65°C ~ 90°C vs. -55°C ~ 85°C), supporting applications with more demanding environmental or electrical specifications.

Selection between the four TE Connectivity variants should be based on connector usage requirements and specific application needs. Part 1934305-1 is designated for Backplane connector usage. All four parts are functionally equivalent with respect to position count, mounting method, termination type, contact finish, and flammability rating.

The primary design consideration is pitch difference: the Molex part operates at 0.053" (1.35mm) pitch, while all TE Connectivity substitutes operate at 0.075" (1.90mm) pitch. PCB layout and mechanical clearance must accommodate this spacing variation.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 1934303-1, 1934304-1, 1934305-1, and 1934306-1 be used interchangeably with Molex 0761551815?

A: The four TE Connectivity parts share identical electrical and mechanical specifications except for connector usage designation. They are interchangeable with each other. However, substitution with the Molex part requires PCB redesign due to pitch difference (0.075" vs. 0.053").

Q: What is the significance of the pitch difference between the Molex and TE Connectivity parts?

A: Pitch determines the center-to-center spacing between connector positions. The Molex 0761551815 uses 0.053" (1.35mm) pitch, while TE Connectivity substitutes use 0.075" (1.90mm) pitch. This difference requires different PCB footprints and cannot be accommodated through simple component swapping.

Q: Are all substitute parts suitable for backplane applications?

A: TE Connectivity part 1934305-1 is explicitly designated for Backplane connector usage. Parts 1934303-1, 1934304-1, and 1934306-1 do not specify connector usage but share identical electrical and mechanical characteristics with 1934305-1.

Q: What packaging formats are available?

A: The Molex 0761551815 is supplied in Tray packaging. All four TE Connectivity substitute parts are supplied in Tube packaging.

Q: Do all parts meet the same compliance standards?

A: Yes. All parts are ROHS3 compliant, UL94 V-0 rated, and carry MSL 1 (Unlimited) moisture sensitivity level. All parts maintain Active product status.

Q: What is the current rating difference?

A: The Molex 0761551815 does not specify a current rating. All TE Connectivity substitutes are rated for 0.5A per contact.
