Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1755642 is determined by the following critical parameters:

• Position Count: Must be 16 positions
• Connector Type: Header with male pins, shrouded (4 side)
• Pitch Tolerance: 5.00mm nominal (5.08mm represents a 0.08mm variance, approximately 1.6% deviation)
• Mounting Configuration: Vertical orientation, through-hole or solder mounting
• Electrical Ratings: Minimum 300V (UL standard), 12A current capacity
• Housing Material: Polyamide (PA) or equivalent thermoplastic
• Compliance: ROHS3 compliant, UL94 V-0 flammability rating

The On Shore Technology Inc. EDSTLZ955/16 qualifies as a substitute based on matching position count, connector type, shrouding configuration, vertical orientation, and compliance certifications. The pitch variance of 0.08mm (5.08mm vs. 5.00mm) falls within acceptable mechanical tolerance for standard PCB layouts designed for 5.00mm spacing, provided board-level verification is performed.

Parameter Comparison

Engineering Selection Recommendations

Both the Phoenix Contact 1755642 and On Shore Technology EDSTLZ955/16 maintain active production status and full ROHS3 compliance with UL94 V-0 flammability certification. Selection between these parts should be based on:

• PCB Design Compatibility: The 0.08mm pitch variance requires verification against PCB layout tolerances. Standard PCB manufacturing typically accommodates ±0.1mm positional tolerance, making the EDSTLZ955/16 mechanically compatible with designs specified for 5.00mm pitch.
• Assembly Process: The Phoenix Contact part is specified for through-hole mounting, while the On Shore Technology part is specified for solder mounting. Both employ solder-based termination; verify assembly equipment and process compatibility.
• Supply Chain Availability: Both parts are in active stock (778 pcs and 987 pcs respectively), supporting equivalent sourcing flexibility.
• Electrical Performance: Both parts meet or exceed the 300V UL rating and 12A current requirement, ensuring functional equivalence in standard applications.

Frequently Asked Questions (FAQ)

Q: Can the On Shore Technology EDSTLZ955/16 be used as a direct replacement for the Phoenix Contact 1755642?

A: Yes, with PCB layout verification. The 0.08mm pitch variance (5.08mm vs. 5.00mm) is within standard PCB manufacturing tolerance. Confirm that the receiving PCB design accommodates this tolerance before assembly.

Q: What is the significance of the pitch difference between these parts?

A: The pitch difference of 0.08mm represents approximately 1.6% deviation from the nominal 5.00mm specification. For a 16-position header, the cumulative tolerance across all positions is approximately 1.2mm, which falls within typical PCB positional tolerance of ±0.1mm per position.

Q: Are there differences in mounting methodology between these parts?

A: The Phoenix Contact 1755642 is specified as through-hole mounting, while the On Shore Technology EDSTLZ955/16 is specified as solder mounting. Both employ solder-based termination to the PCB. Verify that your assembly process and equipment are compatible with the selected part's mounting specification.

Q: Do both parts meet the same compliance and safety standards?

A: Yes. Both parts are ROHS3 compliant and carry UL94 V-0 flammability certification. Both are rated for 300V (UL) and support equivalent electrical performance in standard applications.

Q: What should be verified before implementing the On Shore Technology substitute?

A: Perform the following verification steps: (1) Confirm PCB layout accommodates the 5.08mm pitch tolerance; (2) Verify assembly process compatibility with solder mounting specification; (3) Validate electrical performance in the target application circuit; (4) Confirm mechanical fit within the enclosure or system design.
