FHG.0B.302.CLAD52Z Equivalent & Substitute Parts

Part Overview

The FHG.0B.302.CLAD52Z is a 2-position circular connector plug with male pins and solder cup termination, manufactured by LEMO. This connector features a 302 shell size with push-pull fastening, gold-plated mating contacts, and shielded construction rated for 10A at operating temperatures from -55°C to 250°C. The product is currently obsolete, making identification of equivalent and substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FHG.0B.302.CLAD52Z is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector type: Plug with male pins
• Number of positions: 2
• Termination method: Solder cup
• Fastening mechanism: Push-pull
• Contact finish: Gold plating on mating surfaces
• Ingress protection: IP50 minimum

Secondary Compatibility Criteria:

• Operating temperature range must encompass or exceed the original specification
• Current rating must meet or exceed 10A
• Shell material and finish must support equivalent environmental performance
• Shielding configuration must match application requirements

The FPG.0B.302.CLAD52Z qualifies as a manufacturer-recommended equivalent due to identical electrical and mechanical specifications with active product status. The W20L0C-P02MJG0-520S qualifies as a similar substitute based on matching connector type, position count, termination, fastening, and contact finish, though with noted parameter variations in shell size designation, current rating, operating temperature range, and shielding configuration.

Parameter Comparison

Engineering Selection Recommendations

FPG.0B.302.CLAD52Z (LEMO) is the primary substitute for FHG.0B.302.CLAD52Z. This part maintains identical electrical and mechanical specifications while offering active product status, ensuring ongoing availability and supply chain continuity. Both parts are ROHS3 compliant and REACH unaffected. The FPG.0B.302.CLAD52Z is packaged in bulk format and carries MSL 1 (Unlimited) rating.

W20L0C-P02MJG0-520S (ODU) is a secondary substitute option. This connector maintains core functional compatibility through matching connector type, position count, solder cup termination, push-pull fastening, and gold-plated contacts. However, this part operates at reduced current capacity (7.5A versus 10A), operates within a narrower temperature range (-40°C to 120°C versus -55°C to 250°C), features unshielded construction, and uses a different shell size designation (0 versus 302). The W20L0C-P02MJG0-520S is suitable only for applications where the reduced electrical and thermal specifications are acceptable.

Frequently Asked Questions (FAQ)

Q: Can FPG.0B.302.CLAD52Z directly replace FHG.0B.302.CLAD52Z?

A: Yes. FPG.0B.302.CLAD52Z is the manufacturer-recommended equivalent with identical specifications for connector type, position count, shell size, termination method, fastening type, current rating, operating temperature range, contact finish, and shielding configuration. The primary difference is product status (active versus obsolete) and packaging format.

Q: What are the limitations of W20L0C-P02MJG0-520S as a substitute?

A: W20L0C-P02MJG0-520S operates at 7.5A maximum current versus the original 10A specification, limiting its use to lower-power applications. Operating temperature range is restricted to -40°C to 120°C, making it unsuitable for high-temperature or cryogenic environments. The connector features unshielded construction, which may introduce electromagnetic interference concerns in sensitive applications. Shell size designation differs (0 versus 302), requiring mechanical compatibility verification.

Q: Are all substitute parts RoHS and REACH compliant?

A: Yes. Both FPG.0B.302.CLAD52Z and W20L0C-P02MJG0-520S are ROHS3 compliant and REACH unaffected, matching the compliance status of the original FHG.0B.302.CLAD52Z.

Q: What is the significance of the cable opening specification?

A: Cable opening dimensions define the acceptable cable diameter range for proper connector assembly. FHG.0B.302.CLAD52Z and FPG.0B.302.CLAD52Z specify 0.165" to 0.205" (4.20mm to 5.20mm). W20L0C-P02MJG0-520S specifies 0.157" to 0.205" (4.00mm to 5.20mm), providing a slightly lower minimum tolerance. Verify cable diameter compatibility before substitution.

Q: How does shielding affect connector selection?

A: FHG.0B.302.CLAD52Z and FPG.0B.302.CLAD52Z are shielded connectors, providing electromagnetic interference protection. W20L0C-P02MJG0-520S is unshielded. Applications requiring EMI suppression must use shielded variants. Unshielded substitution is acceptable only in non-sensitive signal environments.
