TE Connectivity AMP Connectors 5-146852-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 5-146852-1 is an active rectangular connector header designed for through-hole board-to-board or cable applications. This unshrouded, cuttable position header operates within the AMPMODU series and features a 0.100" (2.54mm) pitch with male pin contacts and solder termination. The connector is rated for 3A continuous current and operates across a temperature range of -65°C to 105°C. Identification of equivalent and substitute parts becomes necessary when addressing inventory constraints, lead time requirements, or specific application performance criteria while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 5-146852-1 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Contact Type: Male Pin
• Number of Rows: 1
• Mounting Type: Through Hole
• Termination: Solder
• Connector Category: Rectangular Connectors
• Number of Positions: Cuttable

Compatible Variation Parameters:

• Contact Material: Copper Alloy or Phosphor Bronze
• Contact Finish: Tin or Gold
• Insulation Material: Thermoplastic or Liquid Crystal Polymer (LCP)
• Current Rating: Equal to or greater than 3A
• Operating Temperature: Must encompass or exceed -65°C ~ 105°C range
• Flammability Rating: UL94 V-0 or equivalent
• RoHS Compliance: Required

The substitute part 78511-200HLF (Amphenol ICC FCI BERGSTIK® II series) satisfies all mandatory matching parameters and demonstrates compatible variation in contact material, finish, insulation material, current rating, and operating temperature range, while maintaining equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: TE Connectivity 5-146852-1

The TE Connectivity AMP Connectors 5-146852-1 remains the primary specification for applications requiring the AMPMODU series designation. This part maintains active product status with confirmed inventory availability of 19,068 pieces. The connector is RoHS compliant, UL94 V-0 rated, and carries unlimited moisture sensitivity classification (MSL 1). The 3A current rating and -65°C to 105°C operating temperature range address standard industrial and commercial applications.

Substitute Part: Amphenol ICC 78511-200HLF

The Amphenol ICC 78511-200HLF (BERGSTIK® II series) functions as a direct substitute when TE Connectivity 5-146852-1 availability is constrained. This part demonstrates identical mechanical and electrical compatibility across all critical mating parameters. The substitute offers enhanced performance characteristics including a 5A current rating (versus 3A), extended operating temperature range to 125°C (versus 105°C), and phosphor bronze contact material with gold finish. The LCP insulation material provides superior dimensional stability compared to thermoplastic. Both parts maintain identical RoHS compliance, UL94 V-0 flammability rating, and MSL 1 classification. Inventory availability for the substitute is 32,657 pieces.

Selection between these parts depends on application-specific requirements: choose the primary part for AMPMODU series specification compliance; select the substitute when enhanced thermal performance, higher current capacity, or improved contact durability is required.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 78511-200HLF directly replace the TE Connectivity 5-146852-1 in existing designs?

A: Yes. Both connectors share identical pitch (0.100" / 2.54mm), contact type (male pin), row configuration (1 row), mounting method (through hole), and termination (solder). The mechanical and electrical interfaces are fully compatible. The substitute part offers enhanced specifications including higher current rating (5A versus 3A) and extended temperature range (-65°C to 125°C versus -65°C to 105°C).

Q: What are the key differences between these two connector models?

A: The primary differences are contact material (copper alloy versus phosphor bronze), contact finish (tin versus gold), insulation material (thermoplastic versus LCP), current rating (3A versus 5A), and maximum operating temperature (105°C versus 125°C). All other parameters including pitch, position count, row configuration, mounting type, and termination method are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both the TE Connectivity 5-146852-1 and Amphenol ICC 78511-200HLF are RoHS compliant and carry UL94 V-0 flammability ratings. Both maintain MSL 1 (unlimited) moisture sensitivity classification.

Q: What is the significance of the cuttable position feature?

A: The cuttable position feature allows the connector header to be cut to the required number of positions during assembly or integration. Both the primary part and substitute support this functionality, enabling flexible configuration for various application requirements without requiring multiple part numbers.

Q: Does the gold contact finish of the substitute part affect compatibility?

A: No. The gold contact finish on the Amphenol ICC 78511-200HLF is compatible with standard tin-plated receptacles and mating connectors. Gold plating provides enhanced corrosion resistance and contact reliability compared to tin, making it suitable for applications requiring extended service life or exposure to corrosive environments.

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

A: The Amphenol ICC 78511-200HLF is preferred for applications approaching or exceeding 105°C, as it maintains specifications to 125°C. The TE Connectivity 5-146852-1 is rated to 105°C maximum. For applications within the 0°C to 105°C range, both parts are functionally equivalent.

Q: What packaging format is used for both parts?

A: Both connectors are supplied in Cut Tape (CT) packaging, suitable for automated assembly processes and component handling.
