Amphenol ICC 76345-103-12 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76345-103-12 is a through-hole, right-angle rectangular connector header with 12 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This BERGSTIK® series component features male pins with gold-plated mating contacts and is designed for board-to-board applications. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct compatibility without circuit redesign.

Substitute Part Grouping Explanation

Substitution eligibility for the 76345-103-12 is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions and rows (12 positions, 2 rows)
• Mating pitch (0.100" / 2.54mm)
• Row spacing (0.100" / 2.54mm)
• Mounting configuration (Through Hole, Right Angle)
• Style (Board to Board)
• Termination method (Solder)
• Contact shape (Square)
• Flammability rating (UL94 V-0)
• Moisture sensitivity level (MSL 1)

Substitute parts are grouped into two categories: direct manufacturer equivalents from Amphenol ICC and cross-manufacturer alternatives from Molex and TE Connectivity. All listed substitutes maintain the core electrical and mechanical specifications required for direct board-level replacement.

Parameter Comparison

Engineering Selection Recommendations

The 76345-103-12LF from Amphenol ICC is the primary substitute for the obsolete 76345-103-12. Both parts are from the same manufacturer and BERGSTIK® series, with identical mechanical and electrical specifications. The key distinction is product status: 76345-103-12LF is active and RoHS Compliant, whereas the original part is obsolete and RoHS non-compliant. This makes 76345-103-12LF the preferred choice for new designs and ongoing production requiring regulatory compliance.

The Molex 0010894123 (C-Grid 70216 series) and TE Connectivity 5-146309-6 (AMPMODU Mod II series) are cross-manufacturer alternatives that meet all core substitution criteria. Both are active products with current availability and RoHS compliance. The Molex part offers breakaway functionality and is available in tube packaging. The TE Connectivity part provides specified operating temperature range (-65°C ~ 105°C) and current rating (3A), offering additional performance documentation. Both cross-manufacturer options are suitable for applications where multi-source qualification is required.

Frequently Asked Questions (FAQ)

Q: Can the 76345-103-12LF directly replace the obsolete 76345-103-12?

A: Yes. Both parts share identical specifications for connector type, contact configuration, pitch, mounting method, and termination. The primary difference is product status and RoHS compliance. The 76345-103-12LF is the direct Amphenol ICC equivalent and is recommended for replacement.

Q: What are the key differences between Amphenol ICC and cross-manufacturer substitutes?

A: The Amphenol ICC 76345-103-12LF maintains the original BERGSTIK® series design. The Molex 0010894123 and TE Connectivity 5-146309-6 are functionally equivalent but from different series (C-Grid 70216 and AMPMODU Mod II respectively). All three meet the core 12-position, 2.54mm pitch, right-angle through-hole requirements. Cross-manufacturer parts may have minor variations in contact length and insulation height within acceptable tolerances.

Q: Are there packaging differences between these substitutes?

A: Yes. The 76345-103-12LF is supplied in bulk packaging. The Molex 0010894123 is supplied in tube packaging. The TE Connectivity 5-146309-6 is supplied in tray packaging. Packaging selection depends on production volume and handling requirements but does not affect electrical or mechanical compatibility.

Q: Which substitute should be selected for new designs?

A: For new designs requiring RoHS compliance and active product support, the 76345-103-12LF is the primary choice. For applications requiring specified operating temperature range and current rating documentation, the TE Connectivity 5-146309-6 provides additional performance parameters. The Molex 0010894123 is suitable where breakaway functionality and tube packaging are advantageous.

Q: Are all substitutes compatible with existing PCB layouts designed for the 76345-103-12?

A: All listed substitutes maintain the same 0.100" (2.54mm) pitch and 2-row configuration. Minor variations in contact length and insulation height exist but remain within standard PCB design tolerances for through-hole mounting. Board-level compatibility is maintained across all substitutes.
