Engineering Selection Recommendations

Primary Recommendation: Amphenol ICC 75869-108LF

The 75869-108LF is the direct active production equivalent from Amphenol ICC. This part maintains identical electrical and mechanical specifications to the obsolete 75869-108 while achieving RoHS compliance. Selection of this part eliminates any design or assembly compatibility concerns and preserves the original connector series characteristics. The 75869-108LF is available in tube packaging with 1049 pieces in stock.

Secondary Recommendation: HARTING SEK Series (09185505322, 09185505324, 09185506322, 09185506324, 09185507322, 09185507324, 09195506324, 09195507324)

HARTING rectangular connectors meet all critical mating and mechanical parameters required for functional substitution. These parts are ROHS3 compliant and feature specified operating temperature ranges (-55°C to 125°C). Key differences include:

Fastening mechanism: Latch Holder instead of Push-Pull
Insulation material: PBT or PCT glass-filled variants instead of thermoplastic
Contact post length variations: 0.114" (2.90mm) or 0.177" (4.50mm) options
Insulation color: Gray or Beige instead of Blue

Selection from this series requires verification that the latch holder fastening mechanism is compatible with the mating connector system and that the alternative insulation materials meet application requirements.

Compliance Considerations:

The original 75869-108 is RoHS non-compliant. Applications subject to RoHS regulations must transition to either the 75869-108LF or HARTING equivalents, all of which carry current RoHS compliance certifications. All substitute options maintain UL94 V-0 flammability ratings and MSL 1 moisture sensitivity levels consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can the HARTING SEK series connectors directly replace the Amphenol ICC 75869-108 in existing designs?

A: HARTING parts meet all critical mating and mechanical parameters (50 positions, 2.54mm pitch, 2-row configuration, through-hole solder termination, shrouded 4-wall construction). However, the fastening mechanism differs (latch holder versus push-pull). Compatibility depends on whether the mating connector system accommodates the latch holder design. Physical dimensions and contact geometry are compatible.

Q: What is the difference between the 75869-108 and 75869-108LF?

A: The 75869-108LF is the active production equivalent. Primary differences are RoHS compliance status (75869-108LF is RoHS compliant; 75869-108 is non-compliant) and post-contact finish (75869-108LF specifies tin finish on posts; 75869-108 does not specify). All electrical and mechanical mating parameters are identical.

Q: Are there packaging differences among the substitute options?

A: Yes. The 75869-108LF is supplied in tube packaging. HARTING parts are available in bulk, tray, or tube packaging depending on the specific part number. Verify packaging requirements for your procurement and assembly processes.

Q: Do the HARTING parts have specified operating temperature ranges?

A: Yes. All HARTING SEK series equivalents specify -55°C to 125°C operating temperature. The original 75869-108 does not specify an operating temperature range. If your application requires documented temperature specifications, HARTING parts provide this data.

Q: What contact post length options are available in the substitute parts?

A: The original 75869-108 and direct equivalent 75869-108LF specify 0.120" (3.05mm) contact post length. HARTING equivalents offer two options: 0.114" (2.90mm) or 0.177" (4.50mm). Post length affects PCB hole depth requirements and solder joint formation. Verify compatibility with your PCB design specifications.

Q: Are all substitute parts RoHS compliant?

A: The 75869-108LF is RoHS compliant. All HARTING SEK series parts are ROHS3 compliant. The original 75869-108 is RoHS non-compliant. For applications subject to RoHS regulations, use only the compliant alternatives.

Q: What is the difference between the insulation materials used?

A: The original 75869-108 uses thermoplastic glass-filled insulation. The 75869-108LF maintains this material. HARTING parts use either PBT (polybutylene terephthalate) or PCT (polycyclohexylenedimethylene terephthalate), both glass-filled. All materials maintain UL94 V-0 flammability ratings. Material selection may affect chemical resistance and mechanical properties in specific environments.

Q: Can I mix and match contact post lengths from different HARTING part numbers?

A: No. Each HARTING part number represents a complete assembly with fixed contact post length. Do not attempt to mix components from different part numbers. Select the appropriate part number based on your PCB design requirements.
