Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 1-1546551-6 is determined by the following critical parameters:

Primary Compatibility Criteria:

• 16 positions per level
• 0.138" (3.50mm) pitch spacing
• Horizontal with board mating orientation
• Through hole mounting configuration
• Screw-based rising cage clamp wire termination
• 300 V voltage rating
• Wire gauge acceptance of 16-28 AWG minimum

Secondary Compatibility Considerations:

• Current rating of 12 A or greater
• Operating temperature range encompassing -40°C to 110°C
• Polyamide housing material
• Copper alloy contacts with tin plating
• Nickel-plated clamp and screw materials

All identified substitute parts meet the primary compatibility criteria. Variations in secondary parameters are noted in the comparison table and do not preclude functional substitution within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

Molex 0393570016 is suitable for applications requiring full electrical equivalence to the TE Connectivity 1-1546551-6. This part maintains identical current and voltage ratings, wire gauge acceptance, and pitch specifications. The component is active and ROHS3 compliant. The operating temperature range extends to 105°C, which is 5°C lower than the original specification. This part is appropriate for new designs and production applications where RoHS3 compliance is required.

Amphenol PCD ESBM16100 provides electrical and mechanical equivalence with identical current rating, voltage rating, wire gauge, and operating temperature range. This component is active and RoHS compliant. The housing material specification matches the original part (PA66, Nylon 6/6). This part is suitable for applications requiring full parameter alignment with the original component.

Phoenix Contact 1751387 meets primary compatibility criteria with identical pitch, positions, mating orientation, and mounting type. The current rating is 10 A, which is 2 A lower than the original specification. The wire gauge acceptance extends to 30 AWG, providing broader compatibility. Operating temperature range is not specified. This part is active and ROHS3 compliant. Selection of this part requires confirmation that the 10 A current rating is sufficient for the application.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0393570016 be used as a direct replacement for the TE Connectivity 1-1546551-6?

A: The Molex 0393570016 meets all primary compatibility criteria including pitch, position count, mating orientation, mounting type, and wire termination method. Electrical ratings are identical at 12 A and 300 V. The operating temperature range is -40°C to 105°C, which is 5°C lower than the original specification. This part is suitable for direct substitution in applications where the reduced upper temperature limit is acceptable.

Q: What is the significance of the current rating difference in the Phoenix Contact 1751387?

A: The Phoenix Contact 1751387 has a current rating of 10 A compared to 12 A for the original part. This 2 A reduction means the part is suitable only for applications where the maximum current requirement does not exceed 10 A. Applications requiring the full 12 A capacity must use either the Molex 0393570016 or Amphenol PCD ESBM16100.

Q: Are all substitute parts RoHS compliant?

A: All three substitute parts are RoHS compliant. The Molex 0393570016 and Phoenix Contact 1751387 are ROHS3 compliant. The Amphenol PCD ESBM16100 is RoHS compliant. The original TE Connectivity part has RoHS status listed as not applicable due to its obsolete status.

Q: What is the difference between the screw thread specifications?

A: The Molex 0393570016 uses M3 screw threads with a torque specification of 0.31 Nm (2.7 Lb-In). The Phoenix Contact 1751387 uses M2 screw threads with a torque specification of 0.22-0.25 Nm (1.9-2.2 Lb-In). The Amphenol PCD ESBM16100 specifies 0.25 Nm (2.2 Lb-In) torque but does not specify screw thread size. These differences reflect manufacturer design variations and do not affect functional compatibility.

Q: Can the wire gauge acceptance differences affect substitution?

A: All parts accept 16-28 AWG wire as a minimum. The Phoenix Contact 1751387 extends acceptance to 30 AWG, providing broader compatibility with smaller gauge conductors. This difference does not preclude substitution; it indicates the Phoenix Contact part accommodates a wider range of wire sizes.

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

A: The Molex 0393570016 is supplied in bulk packaging. The Phoenix Contact 1751387 is supplied in bulk packaging. The Amphenol PCD ESBM16100 is supplied in tray packaging. Packaging selection should be based on production volume and handling requirements.

Q: Are there any housing material differences between the parts?

A: The TE Connectivity 1-1546551-6 and Amphenol PCD ESBM16100 both specify PA66 (Nylon 6/6) housing material. The Molex 0393570016 and Phoenix Contact 1751387 specify polyamide (PA) or nylon without the specific 6/6 designation. These materials are functionally equivalent for the specified electrical and thermal requirements.
