Direct Amphenol ICC Equivalent: The 75869-305LF is the direct successor from Amphenol ICC, maintaining identical electrical and mechanical specifications while offering RoHS compliance and active product status.

Cross-Manufacturer Alternatives: HARTING SEK series connectors (09185265322, 09185265324, 09185266322, 09185266324, 09185267322, 09185267324, 09195266324, 09195267324) provide functional equivalence with identical position count, pitch, and mounting characteristics. These parts maintain the same shrouded 4-wall construction and through-hole solder termination.

Non-Equivalent Part: The 76382-311LF is listed in the substitute database but does not qualify as a functional equivalent due to differing position count (11 vs. 26) and mounting orientation (right-angle vs. vertical).

Engineering Selection Recommendations

Primary Recommendation: 75869-305LF

The Amphenol ICC 75869-305LF is the direct equivalent and recommended replacement for the obsolete 75869-305. This part maintains identical electrical and mechanical specifications while offering active product status and RoHS compliance. The 305LF variant includes tin plating on the post contacts, providing enhanced corrosion resistance compared to the original specification.

Secondary Recommendations: HARTING SEK Series

The HARTING SEK series connectors (09185265322, 09185265324, 09185266322, 09185266324, 09185267322, 09185267324, 09195266324, 09195267324) provide functional equivalence with the following considerations:

All maintain the required 26-position, 2-row configuration at 2.54mm pitch
All feature shrouded 4-wall construction with through-hole solder termination
All are RoHS3 compliant with active product status
Operating temperature range extends to -55°C ~ 125°C, exceeding the original specification
Contact material differs (copper alloy vs. phosphor bronze), with no impact on standard applications
Insulation material varies between PBT and PCT formulations, both meeting UL94 V-0 flammability requirements
Fastening mechanism differs (latch holder vs. push-pull), requiring mechanical compatibility verification

Compliance Considerations:

All substitute parts listed are RoHS compliant, addressing regulatory requirements that may not have applied to the original 75869-305. The 75869-305LF provides the most direct path for legacy design updates, while HARTING alternatives offer extended temperature performance and alternative packaging options.

Frequently Asked Questions (FAQ)

Q: Can the 75869-305LF be used as a direct drop-in replacement for the 75869-305?

A: Yes. The 75869-305LF maintains identical position count (26), row configuration (2), pitch (2.54mm), mounting type (through-hole), and termination method (solder). The primary differences are product status (active vs. obsolete) and RoHS compliance. The tin plating on post contacts provides improved corrosion resistance.

Q: What is the difference between the Amphenol ICC 75869-305LF and the HARTING SEK series alternatives?

A: The 75869-305LF is manufactured by Amphenol ICC and maintains the original design lineage. HARTING SEK series parts are cross-manufacturer alternatives that meet the same electrical and mechanical interface requirements. Key differences include contact material (phosphor bronze vs. copper alloy), insulation material formulation (thermoplastic vs. PBT/PCT), and fastening mechanism (push-pull vs. latch holder). All maintain the critical 26-position, 2.54mm pitch configuration.

Q: Are there packaging differences among the substitute parts?

A: Yes. The 75869-305LF is supplied in tube packaging. HARTING alternatives are available in bulk or tray packaging. Packaging selection should align with production volume and handling requirements. Electrical and mechanical specifications remain consistent across all packaging options.

Q: Does the contact material difference between phosphor bronze and copper alloy affect performance?

A: Both materials meet the electrical and mechanical requirements for standard 2.54mm pitch header applications. The contact material difference does not impact mating force, current carrying capacity, or reliability in typical board-to-cable interconnection applications. Material selection is driven by manufacturing process and cost considerations.

Q: What is the significance of the operating temperature range difference?

A: The original 75869-305 does not specify an operating temperature range. The 75869-305LF and HARTING alternatives specify -55°C ~ 125°C operation. This extended range provides additional design margin for applications requiring operation across wider temperature extremes. For applications within standard industrial temperature ranges, this difference is not operationally significant.

Q: Can HARTING SEK series connectors be used interchangeably with the Amphenol ICC parts?

A: Electrical and mechanical interface compatibility is maintained across all listed alternatives due to identical position count, pitch, and mounting specifications. However, the fastening mechanism differs (latch holder vs. push-pull), requiring verification that mating connector compatibility is maintained in the specific application. Physical board layout and connector orientation should be confirmed before substitution.

Q: What is the significance of RoHS compliance for this connector?

A: The original 75869-305 is RoHS non-compliant. All substitute parts listed are RoHS compliant (either RoHS or ROHS3 status). RoHS compliance is required for products sold into European markets and many other regulated regions. If the application requires RoHS compliance, the 75869-305LF or HARTING alternatives must be selected.
