FHG.0B.303.CLAD52 Equivalent & Substitute Parts

Part Overview

The FHG.0B.303.CLAD52 is a 3-position circular connector plug with male pins and solder cup termination, manufactured by LEMO. This connector features a shielded design with gold-plated mating contacts, chrome-finished brass shell, and push-pull fastening. The part is classified as obsolete, making identification of active equivalent and substitute parts essential for ongoing system support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FHG.0B.303.CLAD52 is determined by the following critical parameters:

• Connector Type & Pin Configuration: Plug with male pins, 3-position configuration
• Termination Method: Solder cup termination for PCB or cable assembly
• Fastening Mechanism: Push-pull coupling system
• Electrical Performance: Current rating and contact material compatibility
• Environmental Sealing: IP50 ingress protection classification
• Mating Interface: Shell size and insert geometry

The substitute parts listed maintain compatibility across these core parameters while accommodating variations in shell material, shielding configuration, and operating temperature ranges based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

FPG.0B.303.CLAD52 (LEMO) is the manufacturer-recommended substitute for the obsolete FHG.0B.303.CLAD52. This part maintains identical electrical and mechanical specifications, including current rating, operating temperature range, shielding configuration, and contact finish. The primary distinction is active product status, ensuring ongoing availability and manufacturing support. This substitute is the preferred selection for direct replacement applications.

W10L0C-P03MJG0-5200 (ODU MINI-SNAP® L) is an alternative substitute from a different manufacturer. This connector maintains the 3-position male pin configuration, solder cup termination, and push-pull fastening. However, the following parameter variations must be evaluated for application compatibility:

• Operating temperature range reduced to -40°C ~ 120°C (versus -55°C ~ 250°C)
• Current rating of 7.5A (versus 8A)
• Unshielded design (versus shielded)
• Copper alloy shell material (versus brass)
• Slightly reduced cable opening tolerance at lower end (4.00mm minimum versus 4.20mm)

Selection of the ODU substitute requires confirmation that the application does not require the extended temperature range, higher current capacity, or shielding characteristics of the original LEMO design.

Frequently Asked Questions (FAQ)

Q: Can FPG.0B.303.CLAD52 be used as a direct replacement for FHG.0B.303.CLAD52?

A: Yes. FPG.0B.303.CLAD52 maintains identical specifications across all critical parameters: 3-position male pin configuration, solder cup termination, 8A current rating, -55°C to 250°C operating temperature, shielded design, and IP50 ingress protection. The primary difference is product status; FPG.0B.303.CLAD52 is active and currently manufactured.

Q: What are the limitations of using W10L0C-P03MJG0-5200 as a substitute?

A: The ODU MINI-SNAP® L connector has three notable parameter differences: reduced operating temperature range (-40°C to 120°C), lower current rating (7.5A), and unshielded construction. Applications requiring extended temperature operation, higher current capacity, or electromagnetic shielding must use FPG.0B.303.CLAD52 instead.

Q: Are the cable opening tolerances compatible across all three connectors?

A: The cable opening ranges are largely compatible. FHG.0B.303.CLAD52 and FPG.0B.303.CLAD52 specify 0.165" to 0.205" (4.20mm to 5.20mm). W10L0C-P03MJG0-5200 specifies 0.157" to 0.205" (4.00mm to 5.20mm). The ODU part accommodates slightly smaller cable diameters at the lower tolerance limit.

Q: What compliance certifications apply to these connectors?

A: All three connectors carry EAR99 ECCN classification and HTSUS code 8536.69.4020. FHG.0B.303.CLAD52 and FPG.0B.303.CLAD52 are ROHS3 compliant and REACH unaffected. Material flammability rating for LEMO parts is UL94 V-0.

Q: Does packaging differ between the main part and substitutes?

A: FHG.0B.303.CLAD52 packaging is not specified. FPG.0B.303.CLAD52 and W10L0C-P03MJG0-5200 are supplied in bulk packaging. Confirm packaging requirements with procurement specifications.
