Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 6-146293-4 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 14
• Contact Type: Male Pin
• Current Rating: 3A
• Operating Temperature Range: -65°C ~ 105°C

Mechanical Compatibility Parameters:

• Connector Type: Header, Breakaway
• Mounting Type: Through Hole
• Number of Rows: 1
• Contact Shape: Square
• Insulation Material: Liquid Crystal Polymer (LCP)
• Overall Contact Length: 0.440" (11.18mm)

Compliance Parameters:

• RoHS Compliant status
• Material Flammability Rating: UL94 V-0
• Series: AMPMODU Mod II

The substitute part 6-146281-4 maintains full equivalence across all critical parameters. The primary distinction is termination method: the original part supports both Press-Fit and Solder termination, while the substitute supports Solder termination only. This represents a functional subset relationship suitable for applications utilizing solder termination exclusively.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 6-146281-4 is the direct active equivalent for the obsolete 6-146293-4. Both parts belong to the AMPMODU Mod II series and maintain identical electrical and mechanical specifications across all critical parameters including pitch, position count, contact geometry, material composition, and thermal operating range.

Selection Basis:

The 6-146281-4 is recommended for new designs and production applications requiring a 14-position, 0.100" pitch through-hole header connector. The part is currently in active production status with documented inventory availability (686 pieces), ensuring supply chain continuity.

The primary design consideration is termination method. The original 6-146293-4 supported both press-fit and solder termination options. The substitute 6-146281-4 supports solder termination exclusively. Applications utilizing press-fit termination exclusively require alternative evaluation.

Both parts maintain RoHS compliance and UL94 V-0 flammability certification, suitable for industrial and commercial applications within the specified -65°C to 105°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the 6-146281-4 directly replace the 6-146293-4 in existing assemblies?

A: Direct replacement is applicable for applications using solder termination. The 6-146281-4 maintains identical electrical and mechanical specifications including pitch (0.100"), position count (14), contact geometry, and operating temperature range (-65°C to 105°C). If the original assembly utilized press-fit termination exclusively, alternative parts must be evaluated.

Q: What is the primary difference between these two parts?

A: The 6-146293-4 supports both press-fit and solder termination methods, while the 6-146281-4 supports solder termination only. All other electrical and mechanical parameters are identical.

Q: Are both parts RoHS compliant?

A: The 6-146293-4 is documented as RoHS compliant. The 6-146281-4 RoHS status is not specified in the available data. Verification with the manufacturer is required for applications with explicit RoHS compliance requirements.

Q: What is the current rating for these connectors?

A: Both parts are rated for 3A continuous current per contact.

Q: Are these connectors suitable for high-temperature applications?

A: Both parts operate across the temperature range of -65°C to 105°C. Applications requiring operation outside this range require alternative connector selection.

Q: What is the pitch specification for these connectors?

A: Both connectors feature 0.100" (2.54mm) mating pitch, the standard spacing for AMPMODU Mod II series headers.

Q: Can these connectors be used for board-to-board applications?

A: Yes. Both parts are classified as board-to-board or cable connectors with unshrouded design and through-hole mounting.

Q: What contact material is used in these connectors?

A: Both parts utilize copper alloy contacts with gold plating on the mating surface (30.0µin thickness) and tin plating on the post (100.0µin thickness).
