Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FGG.1B.316.CLAD52Z is determined by the following critical parameters:

• Connector Type & Gender: Plug with male pins (fixed requirement)
• Position Count: 16 positions (fixed requirement)
• Termination Method: Solder cup (fixed requirement)
• Fastening Mechanism: Push-pull (fixed requirement)
• Contact Material & Finish: Brass with gold mating finish (fixed requirement)
• Shielding: Shielded construction (fixed requirement)
• Ingress Protection: IP50 minimum (fixed requirement)
• Shell Material: Brass construction (fixed requirement)
• Regulatory Compliance: ROHS3 compliant, REACH unaffected (fixed requirement)

The substitute part S21L0C-P16MCC0-520S meets all critical substitution criteria. Variations in shell size designation, operating temperature range, current rating, and backshell plating specifications do not preclude substitution when the application permits these parameter differences.

Parameter Comparison

Engineering Selection Recommendations

Both the FGG.1B.316.CLAD52Z and S21L0C-P16MCC0-520S are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial and commercial applications.

The FGG.1B.316.CLAD52Z operates across a wider temperature range (-55°C to 250°C) and is specified as shielded. Selection of this part is appropriate for applications requiring extended temperature performance or confirmed shielding requirements.

The S21L0C-P16MCC0-520S provides higher current capacity (4A versus 1.5A) and operates within the -40°C to 120°C range. This part includes strain relief features and is documented for industrial, medical, military, and testing equipment applications. Selection of this part is appropriate when higher current capacity is acceptable and operating temperatures remain within the specified range.

Both parts feature identical contact material (brass), mating finish (gold), insert material (PEEK), and termination method (solder cup), ensuring electrical and mechanical compatibility within their respective operational parameters.

Frequently Asked Questions (FAQ)

Q: Can the S21L0C-P16MCC0-520S directly replace the FGG.1B.316.CLAD52Z in all applications?

A: Direct replacement is possible when the application operates within -40°C to 120°C and does not require current levels exceeding 4A. If the application requires operation below -40°C or above 120°C, or if shielding is a confirmed requirement, the FGG.1B.316.CLAD52Z is the appropriate selection.

Q: What are the mechanical compatibility considerations?

A: Both connectors feature 16-position solder cup termination with push-pull fastening and brass construction with gold-plated contacts. Shell size designations differ (316 versus 1), which may affect physical fit with mating receptacles. Mechanical compatibility must be verified against the mating connector specification.

Q: Are there differences in packaging or inventory considerations?

A: Both parts are supplied in bulk packaging. FGG.1B.316.CLAD52Z has 703 units in stock; S21L0C-P16MCC0-520S has 680 units in stock. Both are active production parts with unlimited moisture sensitivity level (MSL 1).

Q: How do the regulatory certifications compare?

A: Both parts are ROHS3 compliant and REACH unaffected. Both carry EAR99 ECCN classification and identical HTSUS codes (8536.69.4020), indicating equivalent regulatory treatment for export and compliance purposes.

Q: What is the significance of the shielding specification difference?

A: The FGG.1B.316.CLAD52Z is explicitly specified as shielded. The S21L0C-P16MCC0-520S shielding status is not specified in the provided data. Applications requiring electromagnetic interference protection should confirm shielding capability before substitution.
