Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FHG.0B.302.CLAD52 is determined by the following critical parameters:

Primary Matching Criteria:

• Connector type: Plug with male pins
• Number of positions: 2
• Termination method: Solder cup
• Fastening mechanism: Push-pull
• Mounting orientation: Free hanging (in-line), right angle
• Contact finish: Gold plating on mating surfaces
• Ingress protection: IP50 minimum
• Material compliance: UL94 V-0 flammability rating, ROHS3 compliance

Secondary Compatibility Factors:

• Current rating: Minimum 10A
• Operating temperature range: Must encompass -55°C to 250°C or be suitable for the application's actual operating window
• Shell material and finish: Brass with chrome plating
• Insert material: Polyetheretherketone (PEEK)
• Shielding configuration: Shielded design

Two substitute parts meet these criteria with varying degrees of parameter alignment.

Engineering Selection Recommendations

FPG.0B.302.CLAD52 (LEMO Manufacturer Recommended Substitute)

The FPG.0B.302.CLAD52 is the primary equivalent substitute. This part maintains identical electrical and mechanical specifications to the FHG.0B.302.CLAD52, including shell size 302, 10A current rating, -55°C to 250°C operating temperature range, shielded configuration, and gold-plated contacts. Both parts are ROHS3 compliant and feature identical cable opening dimensions. The FPG.0B.302.CLAD52 carries active product status, ensuring ongoing availability and supply chain support. This substitute is suitable for direct replacement in all applications where the original FHG.0B.302.CLAD52 was specified.

W10L0C-P02MJG0-5200 (ODU MINI-SNAP® L Series Alternative)

The W10L0C-P02MJG0-5200 is a cross-manufacturer substitute from ODU's MINI-SNAP® L series. This connector shares the fundamental connector type (2-position plug with male pins, solder cup termination, push-pull fastening), gold-plated contacts, and PEEK insert material. However, this substitute exhibits the following parameter deviations:

• Shell size 0 (versus 302): Different physical envelope
• Current rating 7.5A (versus 10A): Lower current capacity
• Operating temperature -40°C to 120°C (versus -55°C to 250°C): Reduced temperature range
• Unshielded design (versus shielded): Absence of electromagnetic shielding
• Shell finish chrome over nickel (versus chrome): Different plating specification

The W10L0C-P02MJG0-5200 is suitable only for applications where the reduced current rating, narrower temperature range, smaller physical size, and unshielded configuration are acceptable. This part is ROHS3 compliant and carries active product status.

Frequently Asked Questions (FAQ)

Q: Can the FPG.0B.302.CLAD52 be used as a direct replacement for the FHG.0B.302.CLAD52?

A: Yes. The FPG.0B.302.CLAD52 maintains identical specifications across all critical parameters: 2-position configuration, shell size 302, 10A current rating, -55°C to 250°C operating temperature, shielded design, gold-plated contacts, solder cup termination, and push-pull fastening. Physical dimensions and mating interfaces are equivalent. This is the manufacturer-recommended substitute.

Q: What are the limitations of the W10L0C-P02MJG0-5200 as a substitute?

A: The W10L0C-P02MJG0-5200 differs in four critical areas: (1) shell size 0 instead of 302, resulting in a smaller physical envelope and different mating interface; (2) current rating of 7.5A instead of 10A, limiting maximum current capacity; (3) operating temperature range of -40°C to 120°C instead of -55°C to 250°C, restricting use in extreme temperature environments; (4) unshielded configuration instead of shielded, eliminating electromagnetic interference protection. This substitute is applicable only when all these parameter reductions are acceptable for the specific application.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. Both the FPG.0B.302.CLAD52 and W10L0C-P02MJG0-5200 are ROHS3 compliant, matching the compliance status of the original FHG.0B.302.CLAD52.

Q: What is the significance of the shielded versus unshielded configuration?

A: The FHG.0B.302.CLAD52 and FPG.0B.302.CLAD52 feature shielded designs, providing electromagnetic interference (EMI) protection. The W10L0C-P02MJG0-5200 is unshielded. In applications requiring EMI suppression or operating in electromagnetically noisy environments, the shielded configuration is necessary. Unshielded connectors are suitable only for applications without EMI requirements.

Q: How do cable opening dimensions affect substitution?

A: Cable opening dimensions determine the range of cable diameters that can be accommodated. The FHG.0B.302.CLAD52 and FPG.0B.302.CLAD52 accept cables of 0.165" to 0.205" (4.20mm to 5.20mm) diameter. The W10L0C-P02MJG0-5200 accepts 0.157" to 0.205" (4.00mm to 5.20mm). The W10L0C-P02MJG0-5200 accommodates slightly smaller minimum cable diameter but maintains the same maximum. Verify that your cable diameter falls within the acceptable range for the selected substitute.

Q: What inventory status should influence my selection?

A: The FPG.0B.302.CLAD52 (1033 pcs in stock) and W10L0C-P02MJG0-5200 (1170 pcs in stock) both carry active product status with substantial inventory availability. The original FHG.0B.302.CLAD52 (975 pcs in stock) is obsolete. For new designs or long-term production, select from the active status parts to ensure continued supply chain support.
