Amphenol ICC 75869-304 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 75869-304 is a vertical rectangular connector header featuring 20 positions at 2.54mm pitch with shrouded 4-wall design and through-hole solder termination. This part is classified as obsolete, making substitute parts necessary for new designs and ongoing production requirements. Active equivalent models from both Amphenol ICC and alternative manufacturers provide functional compatibility while offering improved product status and compliance certifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters: 20-position configuration, 2-row layout, 0.100" (2.54mm) mating pitch, 0.100" (2.54mm) row spacing, male pin contact type, through-hole mounting, solder termination, shrouded 4-wall design, square contact shape, and keying slot feature.

Substitute parts are grouped into two categories:

Category 1: Direct Amphenol ICC Equivalents — Parts maintaining identical electrical and mechanical specifications with improved product status and RoHS compliance. The 75869-304LF represents the active production equivalent with lead-free post finish and RoHS Compliant certification.

Category 2: Alternative Manufacturer Equivalents — HARTING SEK series parts (09185205322, 09185205324, 09185206322, 09185206324, 09185207322, 09185207324, 09195205324, 09195206324) that maintain core dimensional and functional compatibility. These parts feature extended operating temperature range (-55°C to 125°C), ROHS3 Compliant status, and alternative insulation materials (PBT or PCT glass-filled). Fastening mechanism differs (Latch Holder vs. Push-Pull), and contact length specifications vary.

Category 3: Partial Compatibility — The 76382-310LF represents a right-angle variant with reduced position count (10 positions, single row) and is included for reference only; it does not meet the 20-position, 2-row substitution criteria.

Engineering Selection Recommendations

Primary Recommendation: Amphenol ICC 75869-304LF

The 75869-304LF is the direct active equivalent from the original manufacturer. It maintains identical electrical and mechanical specifications to the 75869-304 while providing RoHS Compliant certification and active product status. This part is suitable for new designs and production continuity without design modification. Packaging is available in Tube format with 3151 units in stock.

Secondary Recommendation: HARTING SEK Series (09185205322, 09185205324, 09185206322, 09185206324, 09185207322, 09185207324, 09195205324, 09195206324)

HARTING SEK series parts provide functional equivalence with extended operating temperature range (-55°C to 125°C) and ROHS3 Compliant certification. These parts are suitable for applications requiring enhanced temperature performance and stricter environmental compliance. Variations in contact post length (0.177" or 0.114") and insulation material (PBT or PCT) allow selection based on specific PCB thickness and thermal requirements. Fastening mechanism differs from the original (Latch Holder vs. Push-Pull), requiring mechanical compatibility verification. Packaging options include Bulk and Tray formats with inventory ranging from 763 to 3982 units.

Not Recommended for Direct Substitution: Amphenol ICC 76382-310LF

The 76382-310LF is a right-angle variant with 10 positions in a single-row configuration. It does not meet the 20-position, 2-row substitution criteria and is included for reference only.

Frequently Asked Questions (FAQ)

Q: Can the 75869-304LF be used as a direct replacement for the obsolete 75869-304?

A: Yes. The 75869-304LF maintains identical connector type, position count, pitch, mounting method, and termination. The primary differences are improved product status (Active vs. Obsolete), RoHS Compliant certification, and tin finish on the post. No design modification is required.

Q: What is the difference between the Amphenol ICC 75869-304LF and HARTING SEK series parts?

A: The 75869-304LF is the direct Amphenol equivalent with identical dimensions and specifications. HARTING SEK series parts offer extended operating temperature range (-55°C to 125°C vs. unspecified), ROHS3 Compliant status, and alternative insulation materials (PBT or PCT). HARTING parts use Latch Holder fastening instead of Push-Pull. Contact post length varies between 0.177" and 0.114" depending on part number.

Q: Are there packaging differences between substitute parts?

A: Yes. The 75869-304LF is supplied in Tube packaging. HARTING SEK series parts are available in Bulk or Tray formats. Packaging selection should align with production volume and handling requirements.

Q: Does the change from Push-Pull to Latch Holder fastening affect compatibility?

A: Fastening mechanism differences may affect mating connector compatibility and insertion force characteristics. Mechanical compatibility with the mating connector must be verified before implementation.

Q: What is the significance of contact post length variation in HARTING parts?

A: Contact post length (0.177" or 0.114") determines engagement depth with the PCB. Selection depends on PCB thickness and solder joint requirements. Verify PCB thickness compatibility with the selected post length.

Q: Are HARTING SEK series parts suitable for high-temperature applications?

A: HARTING SEK series parts are rated for -55°C to 125°C operating temperature, compared to unspecified temperature range for the original 75869-304. This makes them suitable for extended temperature applications. Verify specific application temperature requirements against the rated range.

Q: What is the difference between PBT and PCT insulation materials used in HARTING parts?

A: Both PBT (Polybutylene Terephthalate) and PCT (Polycyclohexylenedimethylene Terephthalate) are glass-filled thermoplastic materials with UL94 V-0 flammability rating. PCT offers enhanced thermal and chemical resistance compared to PBT. Selection depends on specific environmental exposure requirements.

Q: Can the 76382-310LF be used as a substitute?

A: No. The 76382-310LF is a right-angle variant with 10 positions in a single row. It does not meet the 20-position, 2-row configuration requirement and is not electrically or mechanically compatible for direct substitution.
