Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 7-146278-0 is a direct functional equivalent to the 1-104346-8 for applications requiring a 20-position, 0.100" pitch rectangular connector header with through-hole mounting.

Product Status Consideration: The 1-104346-8 carries an obsolete product status, while the 7-146278-0 is active. Selection of the 7-146278-0 ensures access to current manufacturing, quality assurance processes, and ongoing supply availability.

Electrical and Mechanical Compatibility: All critical electrical parameters align between the two parts: 20 positions, 0.100" (2.54mm) pitch, 3A current rating, and -65°C ~ 105°C operating temperature range. Mechanical dimensions, including contact lengths and insulation height, are identical. Both connectors feature square male pin contacts with push-pull fastening and UL94 V-0 flammability rating.

Material and Finish Differences: The 7-146278-0 uses tin contact finish and liquid crystal polymer (LCP) insulation material, compared to tin-lead finish and thermoplastic insulation in the 1-104346-8. These material upgrades represent modern manufacturing standards and provide equivalent or improved performance characteristics within the specified operating parameters.

Compliance Status: Both parts carry EAR99 ECCN classification and 8536.69.4040 HTSUS code. The 1-104346-8 is explicitly RoHS compliant. The 7-146278-0 meets current regulatory requirements for rectangular connector components.

Frequently Asked Questions (FAQ)

Q: Can the 7-146278-0 be used as a direct replacement for the 1-104346-8 in existing designs?

A: Yes. The 7-146278-0 meets all critical electrical and mechanical specifications of the 1-104346-8. Pin count, pitch spacing, contact lengths, current rating, voltage rating, and operating temperature range are identical. The connector is mechanically and electrically compatible for board-to-board applications.

Q: What are the differences between the two parts?

A: The primary differences are product status (obsolete versus active), contact finish material (tin-lead versus tin), insulation material (thermoplastic versus liquid crystal polymer), and termination style (kinked pin solder versus solder). These differences do not affect functional compatibility within the specified electrical and mechanical parameters.

Q: Does the change in contact finish from tin-lead to tin affect performance?

A: No. Tin contact finish meets the same electrical conductivity and reliability requirements as tin-lead finish for this connector category. Tin finish represents current manufacturing standards and provides equivalent performance within the specified operating temperature range of -65°C ~ 105°C and current rating of 3A.

Q: Is the liquid crystal polymer (LCP) insulation material compatible with the original thermoplastic design?

A: Yes. Liquid crystal polymer insulation material is compatible with the original thermoplastic design. Both materials meet UL94 V-0 flammability requirements and provide equivalent insulation performance at the specified operating temperatures and voltage rating.

Q: Are there any PCB layout or footprint changes required when switching from 1-104346-8 to 7-146278-0?

A: No. Both connectors share identical mechanical dimensions, including pitch spacing (0.100"), contact lengths (0.230" mating, 0.120" post), overall contact length (0.440"), and insulation height (0.090"). PCB footprints and mounting hole patterns are identical.

Q: What is the inventory status for the 7-146278-0?

A: The 7-146278-0 is an active product with 1145 pieces in stock as new original inventory.

Q: Are both parts RoHS compliant?

A: The 1-104346-8 is explicitly RoHS compliant. The 7-146278-0 meets current regulatory requirements for rectangular connector components in the AMPMODU Mod II series.

Q: Can the 7-146278-0 be used in applications originally designed for the 1-104346-8 without design modifications?

A: Yes. The 7-146278-0 is a functional equivalent with identical electrical ratings (3A current, 30VAC voltage), mechanical dimensions, and operating temperature range (-65°C ~ 105°C). No design modifications are required for direct substitution in board-to-board or cable interconnection applications.
