Parameter Comparison

Engineering Selection Recommendations

The 5-147103-7 serves as a direct functional substitute for the obsolete 5-147741-7. Both connectors share identical mechanical and electrical specifications within the AMPMODU Mod IV series, including 14-position configuration, 0.100" pitch spacing, surface mount termination, 2A current rating, and -65°C to 125°C operating temperature range.

Primary Distinction: The 5-147103-7 maintains active product status with current manufacturing support, whereas the 5-147741-7 is obsolete. The substitute part incorporates tin plating on mating contacts (150.0µin thickness) compared to the gold plating (30.0µin thickness) of the original part. Both finishes provide equivalent electrical performance for the specified current and temperature ratings.

Compliance Status: The 5-147103-7 carries RoHS compliance certification and REACH unaffected status, ensuring regulatory alignment for new designs and production. Both parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification.

Feature Enhancement: The 5-147103-7 includes board lock capability in addition to pick-and-place features, providing enhanced mechanical retention without compromising interchangeability.

Frequently Asked Questions (FAQ)

Q: Can the 5-147103-7 directly replace the 5-147741-7 in existing designs?

A: Yes. Both connectors share identical mechanical dimensions, electrical ratings, and mating characteristics. The 14-position configuration, 0.100" pitch spacing, surface mount footprint, and 2A current rating are equivalent. The substitute part is mechanically and electrically interchangeable.

Q: What is the difference between gold and tin contact finishes?

A: The 5-147741-7 features gold plating (30.0µin) on mating contacts, while the 5-147103-7 uses tin plating (150.0µin). Both finishes provide adequate electrical conductivity and corrosion resistance for the specified 2A current rating and operating temperature range. Tin plating offers cost efficiency and equivalent performance for this connector class.

Q: Are there any compatibility concerns with PCB footprints?

A: No. Both connectors maintain identical insulation height (0.265"), row spacing (0.100"), and surface mount termination specifications. PCB footprints designed for the 5-147741-7 accommodate the 5-147103-7 without modification.

Q: Why is the original part obsolete?

A: The 5-147741-7 is classified as obsolete by TE Connectivity. The 5-147103-7 represents the current active equivalent within the AMPMODU Mod IV series, ensuring ongoing availability and manufacturing support.

Q: Does the board lock feature on the 5-147103-7 affect mating compatibility?

A: No. The board lock feature provides enhanced mechanical retention during assembly and operation. It does not alter the mating interface or electrical characteristics and remains fully compatible with corresponding plug connectors designed for the AMPMODU Mod IV series.

Q: Are both parts RoHS compliant?

A: Yes. The 5-147741-7 is ROHS3 compliant, and the 5-147103-7 is RoHS compliant. Both parts meet regulatory requirements for lead-free manufacturing and hazardous substance restrictions.

Q: What is the current inventory status?

A: The 5-147741-7 has 803 pieces in stock as new original inventory. The 5-147103-7 has 687 pieces in stock as new original inventory. Both parts are available for immediate procurement.
