TE Connectivity 146134-4 Equivalent & Substitute Parts
Part Overview
The TE Connectivity 146134-4 is a surface mount rectangular connector header from the AMPMODU Mod II series, configured for 10 positions at 0.100" (2.54mm) pitch with 2 rows. This component is classified as obsolete, indicating discontinuation from the manufacturer. The part features male pin contacts with tin-lead finish, solder termination, and push-pull fastening for board-to-board or cable applications. Due to its obsolete status, equivalent and substitute parts are necessary for ongoing design support, production continuity, and component sourcing.

Engineering Selection Recommendations
Primary Recommendation: TE Connectivity 1-146134-7
The 1-146134-7 is the direct equivalent from TE Connectivity and represents the optimal substitution path. This part maintains the same AMPMODU Mod II series designation, identical mechanical and electrical specifications, and achieves active product status. The primary distinction is the contact finish change from tin-lead to tin, which aligns with RoHS compliance requirements. This part is RoHS compliant, addressing regulatory requirements that the obsolete 146134-4 does not meet. With 14,504 units in stock, supply continuity is assured.
Secondary Recommendation: Amphenol ICC (FCI) BERGSTIK® Series
The Amphenol ICC BERGSTIK® series (95278-101-10LF, 95278-101B10LF, 95278-101T10LF, 95278-401-10LF, 95278-401A10LF) provides functionally equivalent alternatives with all critical parameters matched. These parts are active products with RoHS compliance. Selection among these variants depends on packaging requirements and contact finish preference:
- 95278-101-10LF, 95278-101T10LF, 95278-401-10LF: Bulk packaging for high-volume applications
- 95278-101B10LF, 95278-401A10LF: Tape & Reel or tube packaging for automated assembly
- 95278-101-10LF, 95278-101B10LF, 95278-101T10LF: Gold finish contact option for enhanced corrosion resistance
- 95278-401-10LF, 95278-401A10LF: Tin finish contact option for cost optimization
All Amphenol ICC variants maintain the 0.100" (2.54mm) pitch, 10-position, 2-row configuration with surface mount solder termination and push-pull fastening. The insulation height increase from 0.090" to 0.100" and contact length variation from 0.230" to 0.232" are within acceptable mechanical tolerances for board-to-board applications.
Compliance Considerations:
The 146134-4 is RoHS non-compliant with tin-lead finish. All recommended substitutes are RoHS compliant. For applications subject to RoHS regulations, the 1-146134-7 or Amphenol ICC alternatives are mandatory. For legacy applications without RoHS requirements, the 1-146134-7 remains the preferred choice due to series continuity and manufacturer support.
Frequently Asked Questions (FAQ)
Q: Can the TE Connectivity 1-146134-7 be used as a direct replacement for the 146134-4?
A: Yes. The 1-146134-7 is a direct equivalent with identical mechanical and electrical specifications. The primary difference is the contact finish (tin versus tin-lead) and RoHS compliance status. Both parts share the same AMPMODU Mod II series designation, 10-position 2-row configuration, 0.100" pitch, surface mount solder termination, and push-pull fastening. The 1-146134-7 is the recommended substitution path.
Q: What is the difference between the Amphenol ICC BERGSTIK® variants?
A: The BERGSTIK® variants differ in packaging format and contact finish. Packaging options include bulk (95278-101-10LF, 95278-101T10LF, 95278-401-10LF), tube (95278-101B10LF), and tape & reel (95278-401A10LF). Contact finish options are gold (95278-101-10LF, 95278-101B10LF, 95278-101T10LF) or tin (95278-401-10LF, 95278-401A10LF). All variants maintain identical electrical and mechanical specifications. Selection depends on assembly process requirements and finish preference.
Q: Are the insulation height and contact length variations between the 146134-4 and Amphenol ICC parts significant?
A: No. The insulation height increases from 0.090" to 0.100", and contact length varies from 0.230" to 0.232". These variations are within acceptable mechanical tolerances for board-to-board connector applications and do not affect electrical performance or mating compatibility. Both dimensions remain within standard connector design parameters.
Q: Why are the Mill-Max 814 series piston connectors listed as similar but not substitutable?
A: The Mill-Max 814 series uses a piston contact mechanism, fundamentally different from the male pin header design of the 146134-4. While both are 10-position, 2-row, 0.100" pitch surface mount connectors, the contact type difference makes them incompatible for direct substitution. Piston connectors require different mating receptacles and exhibit different electrical and mechanical characteristics.
Q: What is the impact of changing from tin-lead to tin contact finish?
A: The change from tin-lead to tin finish improves RoHS compliance and environmental compatibility. Tin finish provides adequate corrosion resistance for standard applications and maintains equivalent electrical conductivity. The contact finish thickness remains at 100.0µin (2.54µm) for both finishes, ensuring consistent contact resistance and current-carrying capacity.
Q: Are all substitute parts rated for the same operating temperature range?
A: Yes. All recommended substitutes maintain the -65°C to 125°C operating temperature range, identical to the 146134-4. This ensures thermal compatibility across all applications.
Q: What packaging option should be selected for automated assembly?
A: For automated pick-and-place assembly, tape & reel packaging is recommended. The 95278-401A10LF (Amphenol ICC) is available in tape & reel format and includes pick-and-place features. The 95278-101B10LF is available in tube packaging with pick-and-place capability. Bulk packaging options (95278-101-10LF, 95278-101T10LF, 95278-401-10LF) are suitable for manual assembly or high-volume reel-fed processes.
Q: Is RoHS compliance mandatory for all applications?
A: RoHS compliance is mandatory for applications subject to European Union Restriction of Hazardous Substances regulations and equivalent regulations in other jurisdictions. The 146134-4 is RoHS non-compliant due to tin-lead finish. All recommended substitutes (1-146134-7 and Amphenol ICC variants) are RoHS compliant. For new designs and applications in regulated markets, RoHS-compliant parts are required.
Q: Can the gold-finish BERGSTIK® parts be used in place of tin-finish variants?
A: Yes. Gold finish provides enhanced corrosion resistance compared to tin finish and is suitable for all applications where tin finish is acceptable. Gold finish is particularly beneficial for connectors exposed to humid or corrosive environments. The electrical and mechanical specifications remain identical between gold and tin finish variants.
