Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FGA.1B.302.CLAD52Z is determined by the following critical parameters:

• Connector Configuration: 2-position plug with male pins and solder cup termination
• Fastening Mechanism: Push-pull interface for mating and unmating
• Electrical Performance: Shielded design with gold-plated mating contacts
• Environmental Protection: IP50 ingress protection rating
• Termination Method: Solder cup for wire attachment
• Compliance: ROHS3 compliance and REACH unaffected status

The substitute part S21LAC-P02MPH0-520S from ODU meets these core substitution criteria. Both parts share identical connector type, position count, termination method, fastening type, shielding configuration, contact finish, ingress protection rating, and compliance certifications. Variations exist in current rating, operating temperature range, and shell finish specifications, which must be evaluated against application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the FGA.1B.302.CLAD52Z and S21LAC-P02MPH0-520S are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

The FGA.1B.302.CLAD52Z supports a 15A current rating and operates across -55°C to 250°C. Selection of this part is appropriate for applications requiring the full specified current capacity and extended high-temperature operation.

The S21LAC-P02MPH0-520S supports a 12A current rating and operates across -40°C to 120°C. Selection of this part is appropriate for applications where the reduced current rating and narrower operating temperature range are compatible with system requirements. The ODU MINI-SNAP® L series includes strain relief features in addition to backshell provisions.

Component selection must be based on application-specific current requirements, operating temperature limits, and mechanical interface compatibility.

Frequently Asked Questions (FAQ)

Q: Can S21LAC-P02MPH0-520S replace FGA.1B.302.CLAD52Z in all applications?

A: Substitution is valid only when application current requirements do not exceed 12A and operating temperatures remain within -40°C to 120°C. The FGA.1B.302.CLAD52Z is required for applications demanding the full 15A current rating or extended temperature operation to 250°C.

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

A: Both connectors share identical 2-position plug configuration, male pin orientation, solder cup termination, push-pull fastening, shielded design, gold-plated mating contacts, IP50 ingress protection, and PEEK insert material. These parameters ensure mechanical and electrical interface compatibility.

Q: Are there differences in cable opening specifications?

A: Yes. The FGA.1B.302.CLAD52Z accepts cable diameters of 0.165" to 0.205" (4.20mm to 5.20mm), while the S21LAC-P02MPH0-520S accepts 0.157" to 0.205" (4.00mm to 5.20mm). Cable diameter must fall within the specified range for the selected connector.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the significance of the shell finish difference?

A: The FGA.1B.302.CLAD52Z features chrome plating on brass, while the S21LAC-P02MPH0-520S features chrome over nickel plating on brass. Both finishes provide corrosion resistance; the nickel underplate in the ODU part provides additional corrosion protection in certain environments.
