Amphenol ICC 77313-801-26 Rectangular Connector Header — Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 77313-801-26 is a vertical rectangular connector header in the BERGSTIK® series, designed for through-hole board-to-board or cable applications. This 26-position, 2-row connector with 0.100" (2.54mm) pitch provides solder termination and push-pull fastening. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Engineering Selection Recommendations

Primary Recommendation: 77313-801-26LF

The 77313-801-26LF is the direct equivalent from Amphenol ICC, maintaining identical electrical and mechanical specifications while offering active product status. This part is RoHS Compliant and provides the same 0.095" (2.41mm) post contact length as the original 77313-801-26. Selection of this part eliminates cross-manufacturer compatibility concerns and maintains design continuity within the BERGSTIK® series.

Secondary Recommendations for Cross-Manufacturer Substitution:

PBC13DAAN (Sullins Connector Solutions) — Recommended for designs requiring RoHS3 compliance. This part maintains the standard 0.120" (3.05mm) post length and operates across -65°C to 125°C, providing extended temperature range compared to the original specification. Insulation material is polybutylene terephthalate (PBT) rather than thermoplastic, with phosphor bronze contacts.

6-146257-3 (TE Connectivity AMPMODU Mod II) — Recommended for applications requiring RoHS Compliance and extended operating temperature range (-65°C to 105°C). This part uses liquid crystal polymer (LCP) insulation and copper alloy contacts. Insulation height is 0.090" (2.29mm), which may require board layout verification for compatibility.

2326-6121-TG or 2326-6121TB (3M 2300 Series) — Recommended for applications where 3M connector ecosystem integration is required. Both parts maintain standard post length of 0.120" (3.05mm) and operate across -55°C to 105°C. These parts are RoHS non-compliant and use glass-filled thermoplastic insulation with copper alloy contacts.

Extended Post Length Variants (PBC13DABN through PBC13DAFN) — Sullins offers post length options from 0.230" to 0.620" for applications requiring deeper board penetration or specific stack-up configurations. All variants maintain RoHS3 compliance and -65°C to 125°C operating range.

Frequently Asked Questions (FAQ)

Q: Can the 77313-801-26LF directly replace the 77313-801-26 without board redesign?

A: Yes. The 77313-801-26LF maintains identical pitch (0.100"), row spacing (0.100"), contact length mating (0.230"), and post length (0.095"). Footprint compatibility is direct. The primary difference is active product status and RoHS compliance.

Q: What is the impact of post contact length variation on board design?

A: Post contact length determines how far the solder tail extends into the PCB. The original 77313-801-26 uses 0.095" (2.41mm) posts. Substitutes with 0.120" (3.05mm) posts require slightly deeper plated through-holes. Extended variants (0.230" to 0.620") are for applications requiring deeper board penetration and are not direct replacements without board layout modification.

Q: Are Sullins PBC13 series parts fully compatible with the original Amphenol connector?

A: Electrical and mechanical compatibility is confirmed for pitch, row spacing, contact type, and mating contact length. Differences exist in insulation material (PBT vs. thermoplastic), contact material (phosphor bronze vs. phosphor bronze), and operating temperature range (-65°C to 125°C vs. unspecified). Board-level compatibility depends on post length selection.

Q: Which substitute offers the best RoHS compliance status?

A: Sullins PBC13 series (PBC13DAAN, PBC13DABN, PBC13DACN, PBC13DADN, PBC13DAEN, PBC13DAFN) and TE Connectivity 6-146257-3 are ROHS3 Compliant. Amphenol 77313-801-26LF is RoHS Compliant. 3M 2300 series and original 77313-801-26 are RoHS non-compliant.

Q: What is the difference between the 3M 2326-6121-TG and 2326-6121TB?

A: Both are 3M 2300 series headers with identical electrical and mechanical specifications. The primary difference is moisture sensitivity level: 2326-6121-TG is MSL 1 (Unlimited), while 2326-6121TB is Not Applicable. Both maintain 0.120" (3.05mm) post length and -55°C to 105°C operating range.

Q: Can I use the TE Connectivity 6-146257-3 if my board is designed for 0.100" (2.54mm) insulation height?

A: The 6-146257-3 has 0.090" (2.29mm) insulation height, which is 0.010" (0.254mm) lower than the original specification. This may affect board clearance and component placement. Verify board layout compatibility before selection.

Q: What is the current rating for the original 77313-801-26?

A: The original part does not specify a current rating in the provided data. Substitute parts specify 3A per contact. Verify original design current requirements against substitute specifications before implementation.
