Parameter Comparison

Engineering Selection Recommendations

The 104428-4 is an obsolete part. The substitute part 5-146274-6 is the manufacturer-recommended equivalent and is classified as active product status, ensuring ongoing availability and support.

Substitution Basis:

Both parts are manufactured by TE Connectivity AMP Connectors within the AMPMODU Mod II series. The electrical and mechanical specifications are identical across all critical parameters: 6-position, 0.100" pitch, through-hole mounting, 3A current rating, and -65°C to 105°C operating temperature range.

Key Differences:

The primary differences between the main part and substitute are:

1. Product Status: The 104428-4 is obsolete; the 5-146274-6 is active, providing long-term availability and supply chain stability.

2. Contact Finish: The 104428-4 uses Tin-Lead finish; the 5-146274-6 uses Tin finish, reflecting RoHS compliance evolution and lead-free manufacturing standards.

3. Insulation Material: The 104428-4 insulation material is not specified; the 5-146274-6 specifies Liquid Crystal Polymer (LCP), providing enhanced thermal and mechanical properties.

4. Termination Detail: The 104428-4 specifies Kinked Pin, Solder termination; the 5-146274-6 specifies Solder termination, representing a design refinement.

Both parts maintain UL94 V-0 flammability rating, RoHS compliance, and MSL 1 moisture sensitivity level. The 5-146274-6 is suitable for direct substitution in applications currently using the 104428-4.

Frequently Asked Questions (FAQ)

Q: Can the 5-146274-6 be used as a direct replacement for the 104428-4?

A: Yes. Both parts share identical electrical and mechanical specifications across all critical parameters: 6 positions, 0.100" (2.54mm) pitch, through-hole mounting, 3A current rating, and -65°C to 105°C operating temperature. The 5-146274-6 is the manufacturer-recommended substitute.

Q: What is the significance of the contact finish change from Tin-Lead to Tin?

A: The shift from Tin-Lead to Tin reflects RoHS compliance and lead-free manufacturing standards. Both finishes provide equivalent electrical performance and contact reliability at the specified 3A current rating and 30VAC voltage. The Tin finish on the 5-146274-6 meets current environmental and regulatory requirements.

Q: Does the Liquid Crystal Polymer (LCP) insulation material on the 5-146274-6 affect compatibility?

A: No. The LCP insulation material on the 5-146274-6 provides enhanced thermal stability and mechanical properties while maintaining the same insulation height (0.090"), operating temperature range (-65°C to 105°C), and UL94 V-0 flammability rating as the original part. This represents an improvement in material specification.

Q: Are there any packaging differences between the two parts?

A: The 104428-4 packaging is not specified in the available data. The 5-146274-6 is supplied in Bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: What is the difference between Kinked Pin and standard Solder termination?

A: Both termination types are solder-based for through-hole mounting. The Kinked Pin design on the 104428-4 provides additional mechanical retention during soldering. The 5-146274-6 uses standard Solder termination, which is functionally equivalent for through-hole PCB assembly. Both achieve the same electrical and mechanical connection.

Q: Are both parts RoHS compliant?

A: Yes. Both the 104428-4 and 5-146274-6 are RoHS Compliant and carry MSL 1 (Unlimited) moisture sensitivity level, indicating no special storage or handling requirements.

Q: Why is the 104428-4 obsolete?

A: The 104428-4 is classified as obsolete by the manufacturer. The 5-146274-6 represents the active product line continuation within the AMPMODU Mod II series, offering improved material specifications and ongoing manufacturing support.
