Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FGA.0B.302.CLAD42Z are identified based on the following critical parameters that determine functional equivalence:

• 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
• Shielding: Shielded configuration
• Material composition: Brass shell with chrome finish
• Ingress protection: IP50 dust protection
• Compliance: ROHS3 and REACH compliance

The substitute part S20LAC-P02MJG0-420S from ODU meets these core functional requirements. Variations in shell size designation, current rating, operating temperature range, and backshell material plating do not preclude substitution when the primary electrical and mechanical interface parameters align.

Parameter Comparison

Engineering Selection Recommendations

Both the FGA.0B.302.CLAD42Z and S20LAC-P02MJG0-420S are active production components with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

The FGA.0B.302.CLAD42Z supports a higher current rating of 10A and an extended operating temperature range of -55°C to 250°C. The S20LAC-P02MJG0-420S operates at 7.5A with a narrower temperature range of -40°C to 120°C and includes integrated strain relief features.

Selection between these parts depends on application-specific requirements for current capacity and thermal operating conditions. Both connectors maintain equivalent mechanical interface compatibility through identical connector type, position count, termination method, and push-pull fastening mechanism.

Frequently Asked Questions (FAQ)

Q: Can the S20LAC-P02MJG0-420S directly replace the FGA.0B.302.CLAD42Z in all applications?

A: Direct replacement is possible when the application operates within the S20LAC-P02MJG0-420S operating parameters: maximum current of 7.5A and temperature range of -40°C to 120°C. Applications requiring the full 10A current capacity or extended temperature range of -55°C to 250°C require the original FGA.0B.302.CLAD42Z.

Q: What are the key compatibility factors between these two connectors?

A: Both connectors share identical mechanical and electrical interface specifications: 2-position plug configuration, male pins, solder cup termination, push-pull fastening, gold-plated mating contacts, shielded design, and IP50 ingress protection. Cable opening ranges overlap within 0.118" to 0.165" (3.00mm to 4.20mm).

Q: Are there differences in shell finish that affect substitution?

A: The FGA.0B.302.CLAD42Z features chrome plating on brass, while the S20LAC-P02MJG0-420S uses chrome over nickel plating. Both finishes provide equivalent corrosion resistance and electrical performance for the specified applications.

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

A: Cable opening defines the acceptable cable diameter range for proper connector seating. The FGA.0B.302.CLAD42Z accepts 3.20mm to 4.20mm cables, while the S20LAC-P02MJG0-420S accepts 3.00mm to 4.20mm cables. Cables within the overlapping range of 3.20mm to 4.20mm are compatible with both connectors.

Q: Do both connectors meet the same compliance standards?

A: Yes. Both the FGA.0B.302.CLAD42Z and S20LAC-P02MJG0-420S are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component use in regulated industries.
