Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 5-147279-5

The 5-147279-5 is the direct active equivalent from TE Connectivity, maintaining identical mechanical and electrical specifications to the obsolete 147279-5 within the AMPMODU Mod II series. This part is RoHS Compliant and available in Tape & Reel packaging, making it the preferred choice for new designs requiring continuity with existing TE Connectivity connector ecosystems. The primary distinction is the post contact finish change from Tin-Lead to Tin, which is compliant with modern environmental regulations.

Secondary Recommendations: Amphenol ICC (FCI) BERGSTIK® Series

The Amphenol ICC BERGSTIK® series parts (95278-101A20LF, 95278-801A20LF, 95278-801B20LF, 95278-801T20LF) provide functionally equivalent substitution with the following considerations:

All BERGSTIK® variants maintain the critical 2.54mm pitch, 20-position, 2-row configuration
Contact length tolerance is within 0.002" (0.06mm) of the original specification
Insulation height increases from 0.090" to 0.100", which is acceptable for board-to-board applications
All variants are RoHS Compliant with UL94 V-0 flammability rating
Operating temperature range extends to -65°C, exceeding the original specification
Current rating of 3A per contact is specified, providing defined electrical performance
Phosphor Bronze contact material provides enhanced durability compared to Copper Alloy

Tertiary Recommendation: Harwin Inc. M20-8761042

The Harwin M20-8761042 offers cross-manufacturer substitution with the following characteristics:

Maintains all critical pitch and position parameters
Cuttable connector type provides additional design flexibility
Operating temperature range of -40°C to 105°C is suitable for standard industrial applications
Voltage rating of 250V is specified
ROHS3 Compliant status
Brass contact material with defined 3A per contact current rating
Mated stacking heights are specified for multi-connector applications

Compliance Considerations:

The original 147279-5 is RoHS non-compliant with Tin-Lead post finish. All recommended substitutes are RoHS Compliant or ROHS3 Compliant, making them mandatory for new designs subject to environmental regulations. The transition from Tin-Lead to Tin post finish in the 5-147279-5 and all Amphenol variants aligns with modern manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can the 5-147279-5 be used as a direct replacement for the obsolete 147279-5?

A: Yes. The 5-147279-5 is the direct active equivalent with identical mechanical dimensions, pitch, position count, and mating contact specifications. The only functional difference is the post contact finish change from Tin-Lead to Tin, which is a compliance improvement. The part is available in Tape & Reel packaging suitable for automated assembly.

Q: What is the difference between the Amphenol BERGSTIK® variants (95278-101A20LF, 95278-801A20LF, 95278-801B20LF, 95278-801T20LF)?

A: The variants differ in packaging format and contact finish thickness. The "A" suffix indicates Tape & Reel packaging with Pick and Place features. The "B" suffix indicates Tube packaging with Pick and Place features. The "T" suffix indicates Bulk packaging without Pick and Place features. The "801" series has reduced mating contact finish thickness (15.0µin vs. 30.0µin), while the "101" series maintains 30.0µin thickness. All variants maintain identical mechanical compatibility and electrical performance.

Q: Are the Amphenol BERGSTIK® parts mechanically compatible with the original 147279-5?

A: Yes, with minor dimensional tolerance variations. The mating pitch (0.100"), position count (20), row spacing (0.100"), and contact shape (square) are identical. The contact length tolerance is within 0.002" (0.06mm). The insulation height increases from 0.090" to 0.100", which does not affect board-to-board mating compatibility. The fastening type (Push-Pull) is identical.

Q: What is the significance of the "GXT™" contact finish on Amphenol parts?

A: GXT™ is Amphenol's proprietary gold plating specification. It provides enhanced corrosion resistance and contact reliability compared to standard gold plating. The finish thickness of 15.0µin or 30.0µin (depending on variant) meets or exceeds industry standards for connector reliability.

Q: Can the Harwin M20-8761042 be used in applications requiring the exact insulation height of the original 147279-5?

A: The Harwin M20-8761042 has an insulation height of 0.100" compared to the original 0.090". This 0.010" difference is acceptable for board-to-board applications where the connector is mounted on the PCB surface. However, applications with height-constrained designs may require verification of the increased dimension.

Q: What packaging options are available for each substitute part?

A: The TE Connectivity 5-147279-5 is available in Tape & Reel (TR) packaging. Amphenol BERGSTIK® variants are available in Bulk, Tape & Reel (TR), and Tube packaging options. Harwin M20-8761042 is available in Bulk packaging. Selection should be based on assembly process requirements and volume considerations.

Q: Are all substitute parts RoHS Compliant?

A: Yes. The TE Connectivity 5-147279-5 is RoHS Compliant. All Amphenol BERGSTIK® variants are RoHS Compliant. The Harwin M20-8761042 is ROHS3 Compliant. The original 147279-5 is RoHS non-compliant, making substitution necessary for new designs subject to environmental regulations.

Q: What is the current rating for each substitute part?

A: The TE Connectivity 5-147279-5 does not specify a current rating. All Amphenol BERGSTIK® variants are rated at 3A per contact. The Harwin M20-8761042 is rated at 3A per contact. For applications requiring current specifications, the Amphenol and Harwin options provide defined electrical performance.

Q: Can these connectors be used in high-temperature applications?

A: The original 147279-5 does not specify an operating temperature range. The TE Connectivity 5-147279-5 does not specify an operating temperature range. Amphenol BERGSTIK® variants are rated for -65°C to 125°C. The Harwin M20-8761042 is rated for -40°C to 105°C. For applications exceeding 105°C, the Amphenol variants provide extended temperature capability.

Q: What is the difference between "Breakaway" and "Cuttable" connector types?

A: Breakaway connectors have pre-defined break points for individual position separation. Cuttable connectors (such as the Harwin M20-8761042) allow custom cutting at any position along the connector strip, providing greater design flexibility for applications requiring non-standard position counts.
