TE Connectivity 104426-6 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 104426-6 is a vertical rectangular connector header with 8 positions at 2.54mm pitch, designed for through-hole mounting in board-to-board or cable applications. This component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing design and procurement requirements. The connector features male pins with kinked termination, gold-plated mating contacts, and tin-lead plated posts, operating across a temperature range of -65°C to 105°C. Substitution is required for new designs, production continuity, and long-term component availability.

Engineering Selection Recommendations

Primary Recommendation: Amphenol ICC 69190-108HLF

The 69190-108HLF is the preferred substitute for new designs and production transitions. This part is active, RoHS compliant, and operates at an extended temperature range of -65°C to 130°C, exceeding the original specification. The BERGSTIK® II series provides proven reliability in board-to-board applications. The contact length mating specification of 0.230" (5.84mm) differs from the original 0.318" (8.08mm); this variation requires PCB design verification to confirm compatibility with existing socket receptacles.

Secondary Recommendations: Sullins Connector Solutions PBC08 and PEC08 Series

The Sullins PBC08 and PEC08 series connectors provide multiple contact post length options, enabling precise accommodation of various PCB stack-up configurations. All variants are active, ROHS3 compliant, and operate at -65°C to 125°C. Selection between these series depends on mating contact finish requirements:

PBC08 Series: Gold-plated mating contacts (10.0µin thickness)
PEC08 Series: Tin-plated mating contacts (100.0µin thickness)

Within each series, post length variants are designated as follows:

SFAN: 0.120" (3.05mm) post length
SFBN: 0.220" (5.58mm) post length
SFCN: 0.320" (8.13mm) post length
SFDN: 0.420" (10.67mm) post length
SFEN: 0.520" (13.21mm) post length

Compliance Considerations

All substitute parts are RoHS compliant or ROHS3 compliant, addressing regulatory requirements that the original obsolete part does not meet. The original 104426-6 is RoHS non-compliant; substitution with compliant alternatives is necessary for applications subject to RoHS directives.

Inventory Availability

Current stock levels support immediate procurement: Amphenol 69190-108HLF (698 units), Sullins PBC08SFAN (3,187 units), Sullins PEC08SFAN (3,161 units).

Frequently Asked Questions (FAQ)

Q: Can the 69190-108HLF directly replace the 104426-6 without PCB modification?

A: The 69190-108HLF matches all critical electrical and mechanical parameters. However, the mating contact length differs (0.230" versus 0.318"). If the PCB receptacle socket is designed for the original contact length, physical interference or inadequate contact engagement may occur. PCB design review is required to confirm compatibility with existing socket receptacles.

Q: What is the difference between PBC08 and PEC08 series connectors?

A: Both series are functionally equivalent with identical pitch, position count, and mounting characteristics. The primary distinction is mating contact finish: PBC08 features gold plating (10.0µin), while PEC08 features tin plating (100.0µin). Selection depends on application requirements for corrosion resistance and electrical conductivity. Gold-plated contacts (PBC08) are preferred for low-signal applications and harsh environments; tin-plated contacts (PEC08) are suitable for standard industrial applications.

Q: How do I select the correct post length variant within the Sullins series?

A: Post length selection is determined by PCB thickness and the depth of the mating socket receptacle. Measure the total insertion depth required and select the variant that accommodates your stack-up:

SFAN (0.120"): Shallow PCB applications
SFBN (0.220"): Standard single-layer PCB
SFCN (0.320"): Multi-layer PCB with moderate depth
SFDN (0.420"): Deep insertion applications
SFEN (0.520"): Maximum insertion depth

Q: Are all substitute parts rated for the same current and temperature as the original?

A: All substitute parts are rated for 3A current, matching the original specification. Operating temperature ranges exceed the original: Amphenol 69190-108HLF operates to 130°C (versus 105°C original), and Sullins variants operate to 125°C. These extended ranges provide additional design margin and are fully compatible with applications designed for the original temperature specification.

Q: What is the significance of the UL94 V-0 flammability rating?

A: UL94 V-0 indicates that the insulation material meets the highest flammability classification, self-extinguishing within 10 seconds after flame removal. All substitute parts maintain this rating, ensuring compliance with safety standards for consumer and industrial applications.

Q: Can I mix and match connector variants from different manufacturers in the same design?

A: Electrical compatibility is maintained across all listed substitutes due to matching pitch, position count, and contact specifications. However, mechanical compatibility with existing socket receptacles must be verified individually for each part, particularly regarding contact length and insulation height variations. Standardizing on a single manufacturer and series within a design is recommended to minimize compatibility risks.

Q: What is the difference between kinked pin and press-fit termination?

A: The original 104426-6 uses kinked pin termination, where the contact post is bent for mechanical retention during soldering. Substitute parts use either kinked pin or press-fit termination. Press-fit termination provides mechanical interference fit into plated through-holes without solder, offering faster assembly and reduced thermal stress. Both termination methods are electrically and mechanically equivalent for through-hole applications.

Q: Are the substitute parts available in different packaging options?

A: The Amphenol 69190-108HLF is supplied in bulk packaging. Sullins variants are also supplied in bulk. Packaging specifications are provided by distributors; custom packaging or tape-and-reel options may be available through direct manufacturer inquiry.
