Substitute Part Grouping Explanation
Substitution eligibility for the FHG.0B.309.CLAD52Z is determined by the following critical parameters:
Primary Matching Criteria:
- Connector type: Plug with male pins
- Number of positions: 9
- Termination method: Solder cup
- Fastening mechanism: Push-Pull
- Mounting configuration: Free Hanging (In-Line), Right Angle
- Contact finish: Gold-plated mating surfaces
- Shell material: Brass construction
- Ingress protection: IP50 minimum
Secondary Compatibility Parameters:
- Operating temperature range compatibility
- Current rating capability
- Cable opening dimensions
- Shielding configuration
- Insert material composition
Two substitute parts are identified based on these criteria. The first substitute (FPG.0B.309.CLAD52Z) maintains identical specifications across all primary and secondary parameters, representing a direct equivalent. The second substitute (W20L0C-P09MCC0-520S) shares the core connector architecture but introduces variations in specific electrical and thermal ratings that must be evaluated for application suitability.

Engineering Selection Recommendations
FPG.0B.309.CLAD52Z (LEMO) - Recommended Equivalent
This part is the direct equivalent to the obsolete FHG.0B.309.CLAD52Z. All electrical, mechanical, and environmental specifications are identical. The FPG.0B.309.CLAD52Z maintains active product status and is ROHS3 compliant with REACH unaffected certification. This part is suitable for direct replacement in all applications where the original FHG.0B.309.CLAD52Z was specified. Current inventory availability is 992 pieces.
W20L0C-P09MCC0-520S (ODU) - Conditional Substitute
This ODU MINI-SNAP connector shares the core 9-position circular connector architecture with solder cup termination and push-pull fastening. The part maintains gold-plated mating contacts, PEEK insert material, and IP50 ingress protection. However, the following parameter differences must be evaluated for application compatibility:
- Operating temperature range is limited to -40°C ~ 120°C, compared to -55°C ~ 250°C for the original part
- Current rating is 4A, exceeding the 2A requirement of the original part
- Shielding is unshielded, whereas the original part is shielded
- Shell finish is chrome over nickel rather than chrome
- Voltage rating is specified at 200V
This substitute is suitable only for applications where the reduced operating temperature range and unshielded configuration are acceptable. The part is ROHS3 compliant and REACH unaffected. Current inventory availability is 749 pieces.
Frequently Asked Questions (FAQ)
Q: Can FPG.0B.309.CLAD52Z be used as a direct replacement for FHG.0B.309.CLAD52Z?
A: Yes. The FPG.0B.309.CLAD52Z is the direct equivalent. All specifications including connector type, pin count, termination method, current rating, operating temperature range, and shielding configuration are identical. The only difference is product status: FPG.0B.309.CLAD52Z is active while FHG.0B.309.CLAD52Z is obsolete.
Q: What are the key differences between the LEMO and ODU substitutes?
A: The LEMO FPG.0B.309.CLAD52Z is a direct equivalent with identical specifications. The ODU W20L0C-P09MCC0-520S is a functional substitute with the same connector architecture but differs in operating temperature range (-40°C ~ 120°C vs. -55°C ~ 250°C), current rating (4A vs. 2A), shielding (unshielded vs. shielded), and shell finish (chrome over nickel vs. chrome).
Q: Is the ODU W20L0C-P09MCC0-520S suitable for high-temperature applications?
A: No. The ODU substitute has a maximum operating temperature of 120°C, which is significantly lower than the original part's 250°C maximum. Applications requiring operation above 120°C must use the LEMO FPG.0B.309.CLAD52Z equivalent.
Q: Does the unshielded configuration of the ODU substitute affect electromagnetic compatibility?
A: The ODU W20L0C-P09MCC0-520S is unshielded, whereas the original FHG.0B.309.CLAD52Z and equivalent FPG.0B.309.CLAD52Z are shielded. Applications requiring shielding for EMI/RFI suppression must use the shielded LEMO equivalent.
Q: Are both substitute parts RoHS and REACH compliant?
A: Yes. Both FPG.0B.309.CLAD52Z and W20L0C-P09MCC0-520S are ROHS3 compliant and REACH unaffected, matching the compliance status of the original FHG.0B.309.CLAD52Z.
Q: What is the cable opening tolerance for each part?
A: FHG.0B.309.CLAD52Z and FPG.0B.309.CLAD52Z both accept cable diameters of 0.165" ~ 0.205" (4.20mm ~ 5.20mm). The ODU W20L0C-P09MCC0-520S accepts 0.157" ~ 0.205" (4.00mm ~ 5.20mm), providing a slightly wider lower tolerance.
