Engineering Selection Recommendations

Primary Recommendation: 5-146128-7

The 5-146128-7 is the manufacturer-recommended direct equivalent from TE Connectivity AMP Connectors. This part maintains identical electrical and mechanical specifications to the 146128-7 while offering active product status and ROHS3 compliance. The 5-146128-7 is the preferred choice for direct replacement in existing designs and new production runs.

Secondary Recommendations: Amphenol ICC BERGSTIK® Series

The Amphenol ICC BERGSTIK® series parts (95293-101-09LF, 95293-401-09LF, 95293-401B09LF, 95293-801-09LF) are functionally equivalent alternatives.

Frequently Asked Questions (FAQ)

Q: Can the 5-146128-7 be used as a direct replacement for the 146128-7?

A: Yes. The 5-146128-7 is the manufacturer-recommended equivalent and maintains identical electrical and mechanical specifications. The primary difference is active product status and ROHS3 compliance.

Q: What are the key differences between the TE Connectivity and Amphenol ICC options?

A: Both manufacturers provide functionally equivalent parts meeting the same critical parameters. The TE Connectivity 5-146128-7 maintains the original AMPMODU Mod II series designation. The Amphenol ICC BERGSTIK® series parts offer extended operating temperature range (-65°C to 130°C versus -65°C to 105°C) and phosphor bronze contact material. All parts are electrically and mechanically compatible.

Q: Are the Amphenol ICC BERGSTIK® parts interchangeable with each other?

A: Yes. The four BERGSTIK® variants (95293-101-09LF, 95293-401-09LF, 95293-401B09LF, 95293-801-09LF) are interchangeable in terms of electrical and mechanical function. Differences exist in contact finish type, finish thickness, and packaging format. Selection should be based on application requirements for contact finish durability and production assembly method.

Q: What is the significance of the insulation height difference between 0.090" and 0.100"?

A: The insulation height variation from 0.090" (146128-7 and 5-146128-7) to 0.100" (BERGSTIK® series) falls within acceptable mechanical tolerance for board-to-board connector applications. This minor dimensional difference does not affect electrical performance or mating compatibility.

Q: Why do the Amphenol ICC parts have higher operating temperature ratings?

A: The BERGSTIK® series is rated to -65°C to 130°C, compared to the original specification of -65°C to 105°C. This extended range reflects the thermoplastic insulation material and phosphor bronze contact construction used in the BERGSTIK® design. Applications operating within the original -65°C to 105°C range are fully supported by all substitute parts.

Q: What is the GXT™ coating mentioned on certain BERGSTIK® parts?

A: GXT™ is a proprietary gold plating technology applied to contact surfaces. Parts 95293-101-09LF and 95293-801-09LF feature this coating for enhanced corrosion resistance and contact reliability. The GXT™ designation indicates premium contact finish quality.

Q: How does RoHS compliance affect part selection?

A: The original 146128-7 is RoHS non-compliant. All substitute parts listed are RoHS compliant, meeting current regulatory requirements for electronic components in most markets. The 5-146128-7 carries ROHS3 certification, representing the most current compliance standard.

Q: What packaging option should be selected for high-volume production?

A: For high-volume automated assembly, the 95293-401B09LF in tube packaging with Pick and Place feature is optimized for production efficiency. For lower volumes or manual assembly, bulk or bag packaging options are available.

Q: Are there any electrical performance differences between the substitute parts?

A: No. All substitute parts maintain the same 3A current rating, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity level. Electrical performance is equivalent across all listed parts.
