TE Connectivity 6-146257-0 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 6-146257-0 is a vertical rectangular connector header with 20 positions at 2.54mm pitch, designed for through-hole board-to-board or cable applications. This connector features male pins with gold-plated mating contacts and tin-plated posts, housed in a liquid crystal polymer (LCP) insulation body. The part is active in production and widely used in general-purpose electronic assemblies requiring reliable interconnection with 3A current capacity per contact.

Substitute parts are necessary when the primary part is unavailable, when alternative contact finishes or post lengths are required for specific application requirements, or when sourcing from alternative manufacturers provides supply chain advantages.

67997 Series (0.120" post length): Matches the primary part's post length, providing direct mechanical compatibility
68602 Series (0.150" post length): Accommodates thicker PCB assemblies or applications requiring extended post engagement

Contact finish options include gold with 30.0µin thickness (120HLF variants), gold with 15.0µin thickness (220HLF variants), and tin with 100.0µin thickness (420HLF variants). All BERGSTIK® II variants maintain UL94 V-0 rating, 3A current capacity, and MSL 1 classification.

Selection Criteria:

For direct mechanical and electrical replacement: Select 67997-120HLF or 67997-220HLF (matching 0.120" post length)
For thinner PCB assemblies: Select 67996 series variants
For thicker PCB assemblies: Select 68602 series variants
For gold contact finish: Select 120HLF or 220HLF variants
For tin contact finish: Select 420HLF variants
For extended temperature operation: Select any BERGSTIK® II variant (130°C maximum)

All substitute parts maintain active production status and full compliance with RoHS and MSL requirements.

Frequently Asked Questions (FAQ)

Q: Can Molex 0010897201 and 0010897202 be used interchangeably with the TE Connectivity 6-146257-0?

A: Yes, both Molex parts are functionally equivalent. The primary difference is contact finish: 0010897201 features tin mating contacts while 0010897202 features gold mating contacts. Selection depends on application requirements for contact corrosion resistance and electrical performance. Both maintain identical pitch, position count, and electrical ratings.

Q: What is the difference between the Amphenol ICC BERGSTIK® II variants (67996, 67997, 68602)?

A: The primary difference is contact post length. The 67996 series has 0.095" posts, the 67997 series has 0.120" posts (matching the TE part), and the 68602 series has 0.150" posts. Post length selection depends on PCB thickness and solder joint depth requirements. The 67997 series provides direct mechanical compatibility with the primary part.

Q: Are all substitute parts RoHS compliant?

A: Yes, all listed substitute parts maintain RoHS compliance. The TE Connectivity 6-146257-0 is ROHS3 compliant, while Amphenol ICC parts are RoHS compliant. Molex parts are ROHS3 compliant. All parts meet current regulatory requirements for lead-free solder applications.

Q: What is the difference between gold and tin contact finishes?

A: Gold contact finish provides superior corrosion resistance and lower contact resistance, suitable for high-reliability applications and environments with potential corrosive exposure. Tin contact finish is cost-effective and suitable for general-purpose applications with controlled environmental conditions. The TE Connectivity 6-146257-0 uses gold mating contacts with 30.0µin thickness. Substitute parts offer both options with varying thickness specifications.

Q: Can I use a substitute part with a different post length?

A: Post length selection depends on PCB thickness and solder joint requirements. The 67997 series (0.120" posts) provides direct mechanical compatibility with the primary part. The 67996 series (0.095" posts) is suitable for thinner assemblies, while the 68602 series (0.150" posts) accommodates thicker PCB stacks. Verify PCB stack-up thickness before selecting alternative post lengths.

Q: What is the operating temperature difference between the primary part and BERGSTIK® II substitutes?

A: The TE Connectivity 6-146257-0 operates from -65°C to 105°C. All Amphenol ICC BERGSTIK® II variants operate from -65°C to 130°C, providing 25°C additional high-temperature capability. This extended range is beneficial for applications in elevated-temperature environments or equipment with thermal management constraints.

Q: Are there packaging differences between substitute parts?

A: Yes, the TE Connectivity 6-146257-0 is supplied in bulk packaging, while Molex C-Grid 70280 parts are bulk packaged and Amphenol ICC BERGSTIK® II parts are bag packaged. Packaging format does not affect electrical or mechanical performance but may influence inventory management and handling procedures.

Q: What contact material differences exist between substitute parts?

A: The TE Connectivity 6-146257-0 uses copper alloy contacts. Molex C-Grid 70280 parts also use copper alloy contacts. Amphenol ICC BERGSTIK® II parts use phosphor bronze contacts, which provide enhanced spring properties and contact durability. Both materials are suitable for the specified 3A current rating and operating conditions.

Q: Can I mix substitute parts from different manufacturers in the same assembly?

A: While all listed parts are mechanically and electrically compatible, it is recommended to use parts from a single manufacturer within a single assembly to ensure consistent performance characteristics, contact finish properties, and long-term reliability. Mixed-manufacturer assemblies may introduce variability in contact resistance and mating force characteristics.
