TE Connectivity 1-146134-4 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-146134-4 is a rectangular connector header for surface mount applications, featuring 30 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing. This component is classified as obsolete within the AMPMODU Mod II series. The connector utilizes male pins with solder termination and push-pull fastening, designed for board-to-board or cable interconnection applications.

Due to the obsolete product status of the 1-146134-4, equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for new production runs and field replacements. Active alternatives from TE Connectivity and other manufacturers provide functionally compatible solutions with improved compliance certifications and extended availability.

Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 2-146134-1

The 2-146134-1 is the direct manufacturer-recommended equivalent for the obsolete 1-146134-4. This part maintains identical mechanical and electrical specifications while offering active product status and ROHS3 compliance. The primary distinction is the contact finish, which transitions from Tin-Lead to Tin. This change aligns with modern RoHS directives and does not compromise electrical performance or mechanical compatibility. The 2-146134-1 is available in Tube packaging with 1,339 units in stock.

Secondary Recommendations: Amphenol ICC BERGSTIK® Series

The Amphenol ICC BERGSTIK® series (95278-101-30LF, 95278-101A30LF, 95278-101B30LF, 95278-801-30LF, 95278-801B30LF) provides functionally equivalent alternatives with active product status and RoHS compliance. These parts maintain the 30-position, 2-row configuration with 0.100" pitch and push-pull fastening. Variations exist in packaging (Bulk, Tape & Reel, Tube) and contact finish thickness (30.0µin or 15.0µin gold plating). The insulation height is 0.100" (2.54mm) compared to the main part's 0.090" (2.29mm), and the contact material is Phosphor Bronze rather than Copper Alloy. These differences do not affect functional compatibility in standard applications.

Tertiary Recommendations: Samtec TSM Series

The Samtec TSM series (TSM-115-01-F-DV, TSM-115-01-F-DV-A, TSM-115-01-F-DV-A-P, TSM-115-01-F-DV-A-P-TR) offers active alternatives with ROHS3 compliance and LCP insulation material matching the original part. These connectors feature cuttable headers and gold contact finish. The operating temperature range is -55°C ~ 125°C, which is narrower than the original -65°C ~ 125°C specification. Samtec variants include optional board guides and pick-and-place features. Current rating specifications are not provided for these parts.

Compliance Considerations

The original 1-146134-4 is RoHS non-compliant and REACH-affected. All recommended substitutes are RoHS-compliant (either RoHS3 or RoHS Compliant), making them suitable for applications requiring modern environmental compliance. The 2-146134-1 and Samtec TSM series are REACH-unaffected, while Amphenol ICC parts are REACH-affected.

Frequently Asked Questions (FAQ)

Q: Can the 2-146134-1 directly replace the 1-146134-4 in existing designs?

A: Yes. The 2-146134-1 is the manufacturer-recommended equivalent with identical pin count (30), row configuration (2 rows), pitch spacing (0.100"), mounting type (surface mount), and termination method (solder). The contact finish change from Tin-Lead to Tin does not affect mechanical or electrical compatibility. The part is pin-compatible and footprint-compatible.

Q: What is the difference between the Amphenol ICC BERGSTIK® variants (95278-101-30LF, 95278-101A30LF, 95278-101B30LF, 95278-801-30LF, 95278-801B30LF)?

A: The primary differences are packaging format and contact finish thickness. The 95278-101 series uses 30.0µin (0.76µm) gold plating, while the 95278-801 series uses 15.0µin (0.38µm) gold plating. The "A" and "B" suffixes indicate Tape & Reel and Tube packaging respectively, while parts without these suffixes are supplied in Bulk. All variants maintain identical electrical and mechanical specifications for the 30-position, 2-row configuration.

Q: Are the Samtec TSM series parts compatible with the original 1-146134-4?

A: The Samtec TSM series parts are mechanically and electrically compatible for standard applications. Key compatibility factors include identical 30-position, 2-row configuration, 0.100" pitch, surface mount termination, and push-pull fastening. The operating temperature range for Samtec parts is -55°C ~ 125°C, which is narrower than the original -65°C ~ 125°C. Applications requiring operation below -55°C should use the 2-146134-1 or Amphenol ICC alternatives.

Q: What packaging options are available for these substitute parts?

A: Packaging options vary by manufacturer and part number. The 2-146134-1 is supplied in Tube packaging. Amphenol ICC BERGSTIK® parts are available in Bulk, Tape & Reel (TR), and Tube formats. Samtec TSM series parts are primarily supplied in Tube packaging, with some variants offering Tape & Reel options. Specific packaging requirements should be confirmed against individual part numbers.

Q: Does the insulation height difference between parts affect compatibility?

A: The insulation height variation (0.090" for the original part versus 0.100" for most substitutes) does not affect functional compatibility in standard board-to-board applications. This dimension relates to the physical profile of the connector body. PCB footprint designs accommodating the original 0.090" height will also accommodate the 0.100" height without mechanical interference in typical applications.

Q: Are there RoHS compliance differences between the substitute options?

A: Yes. The 2-146134-1 and Samtec TSM series are ROHS3 Compliant. The Amphenol ICC BERGSTIK® series parts are RoHS Compliant. Both compliance levels meet current environmental regulations. The original 1-146134-4 is RoHS non-compliant. For applications requiring ROHS3 certification specifically, the 2-146134-1 or Samtec options are preferred.

Q: What is the difference between Tin-Lead and Tin contact finishes?

A: The original 1-146134-4 uses Tin-Lead contact finish, while the 2-146134-1 uses Tin. Tin finish is the modern standard aligned with RoHS directives that restrict lead content. Both finishes provide equivalent electrical conductivity and corrosion resistance for standard applications. The transition from Tin-Lead to Tin does not impact electrical performance or mechanical mating characteristics.

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

A: All listed substitute parts maintain the same 30-position, 2-row, 0.100" pitch configuration and are mechanically compatible with identical mating connectors. However, for consistency in manufacturing and quality control, using a single part number across an assembly is recommended. If mixing is necessary, ensure all parts meet the same compliance requirements and operating temperature specifications for the application.

Q: Which substitute part offers the best long-term availability?

A: The 2-146134-1 is the manufacturer-recommended equivalent from TE Connectivity and represents the direct replacement path for the obsolete 1-146134-4. As the primary recommendation from the original manufacturer, it offers the most predictable long-term availability and support. Current inventory shows 1,339 units in stock.
