Key Parameters

Substitute Part Grouping Explanation

The FPG.1K.308.CLAK80Z qualifies as a direct substitute based on the following critical parameters:

Matching Parameters:

• Connector type: Plug, Male Pins
• Number of positions: 8
• Shell size - insert: 308
• Termination method: Solder Cup
• Fastening type: Push-Pull
• Shell material and finish: Brass, Chrome
• Contact finish: Gold
• Shielding: Shielded
• Current rating: 5A
• Cable opening: 0.299" ~ 0.315" (7.60mm ~ 8.00mm)
• Insert material: Polyetheretherketone (PEEK)
• Backshell material and plating: Brass, Chrome

Differing Parameters:

• Product status: Active (versus Obsolete)
• Operating temperature range: -55°C ~ 250°C (versus -55°C ~ 200°C)
• Ingress protection: IP50 (versus IP66/IP68)

The substitute maintains all critical electrical and mechanical compatibility parameters. Differences in operating temperature range and ingress protection rating reflect the active product's enhanced specifications.

Parameter Comparison

Engineering Selection Recommendations

The FPG.1K.308.CLAK80Z is the manufacturer-recommended substitute for the obsolete FHG.1K.308.CLAK80Z. Both components are LEMO 1K series products with identical mechanical and electrical interfaces.

Selection Basis:

The substitute maintains full compatibility across all critical connector parameters: 8-position configuration, 308 shell size, solder cup termination, push-pull fastening, brass construction with chrome plating, gold contact finish, and 5A current rating. Both components feature PEEK inserts and shielded construction.

The substitute offers an extended operating temperature range (-55°C to 250°C versus -55°C to 200°C), providing enhanced thermal capability. The ingress protection rating differs (IP50 versus IP66/IP68); applications requiring the higher IP66/IP68 rating must evaluate whether the substitute's IP50 rating meets environmental exposure requirements.

Both components comply with UL94 V-0 flammability standards and carry identical export classification (EAR99) and tariff codes (8536.69.4020).

Frequently Asked Questions (FAQ)

Q: Are FHG.1K.308.CLAK80Z and FPG.1K.308.CLAK80Z mechanically interchangeable?

A: Yes. Both connectors share identical shell size (308), pin count (8), termination method (solder cup), and fastening mechanism (push-pull). Mating interfaces are fully compatible.

Q: What is the difference in ingress protection between these parts?

A: The original part is rated IP66/IP68 (dust tight, water resistant, waterproof). The substitute is rated IP50 (dust protected). Applications exposed to water immersion or high-pressure water jets must confirm that IP50 protection is adequate.

Q: Can the substitute handle higher temperatures than the original?

A: The substitute operates to 250°C maximum, compared to 200°C for the original. Both maintain the same minimum operating temperature of -55°C. Applications requiring operation above 200°C benefit from the substitute's extended range.

Q: Are the solder cup terminations identical?

A: Yes. Both components use solder cup termination with identical cable opening specifications (0.299" ~ 0.315" / 7.60mm ~ 8.00mm). Soldering procedures and wire gauge compatibility are equivalent.

Q: What is the current-carrying capacity?

A: Both parts are rated for 5A continuous current. This rating applies to the complete connector assembly under specified operating conditions.

Q: Are both parts RoHS compliant?

A: The original part is explicitly ROHS3 compliant. RoHS compliance status for the substitute is not specified in available documentation.

Q: Can these connectors be used in high-vibration applications?

A: Both employ push-pull fastening with backshell support. The mechanical design is suitable for applications with moderate vibration. Specific vibration environment requirements should be evaluated against connector retention specifications.
