Substitute Part Grouping Explanation

Substitution between 520993-1 and 521844-1 is valid based on the following matching parameters:

• Terminal Type: Both components are Power Ring terminals
• Wire Gauge: Both accommodate 12-16 AWG wire
• Manufacturer: Both are manufactured by TE Connectivity AMP Connectors
• Moisture Sensitivity Level: Both rated MSL 1 (Unlimited)
• ECCN Classification: Both classified as EAR99
• HTSUS Code: Both assigned code 8536.90.4000

The primary difference between these parts is the termination method: 520993-1 uses crimp termination, while 521844-1 uses screw termination. This distinction requires evaluation based on the specific application requirements and assembly process compatibility.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 520993-1 is classified as obsolete, while 521844-1 is active. For new designs and ongoing procurement, 521844-1 is the appropriate selection to ensure long-term component availability and supply chain continuity.

Compliance Status: The 521844-1 carries ROHS3 compliance certification, whereas the 520993-1 lists RoHS status as not applicable. For applications subject to RoHS directives, 521844-1 satisfies regulatory requirements.

Termination Method Compatibility: Selection between these parts depends on assembly process requirements. The crimp termination of 520993-1 requires crimping equipment and tooling, while the screw termination of 521844-1 requires screwdriver assembly. Existing assembly infrastructure and tooling availability should determine the appropriate selection.

Electrical and Mechanical Equivalence: Both parts maintain identical wire gauge capacity (12-16 AWG), terminal type (Power Ring), and environmental ratings (MSL 1). These parameters confirm functional equivalence for power distribution applications within the specified wire gauge range.

Frequently Asked Questions (FAQ)

Q: Can 521844-1 directly replace 520993-1 in existing assemblies?

A: Functional replacement is possible due to matching terminal type, wire gauge, and environmental ratings. However, the termination method differs: 520993-1 requires crimp termination while 521844-1 requires screw termination. Assembly process compatibility must be evaluated before implementation.

Q: What is the significance of the obsolete status for 520993-1?

A: Obsolete status indicates the part is no longer manufactured or supported by TE Connectivity. For new designs and ongoing production, 521844-1 should be selected to ensure procurement availability and manufacturer support.

Q: Are there packaging differences between these parts?

A: Yes. The 521844-1 is packaged in boxes with 6607 pieces in stock. The 520993-1 packaging specification is not provided. Packaging format may affect ordering quantities and storage requirements.

Q: Do both parts meet the same regulatory standards?

A: Both parts share identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications. The 521844-1 carries ROHS3 compliance certification, while 520993-1 lists RoHS status as not applicable. For RoHS-regulated applications, 521844-1 is the compliant choice.

Q: What wire gauges are supported by these terminals?

A: Both 520993-1 and 521844-1 support 12-16 AWG wire gauge. This range accommodates standard power distribution applications within the specified conductor size limits.

Q: How does the termination method affect component selection?

A: Termination method selection depends on application requirements and assembly capabilities. Crimp termination (520993-1) provides permanent connections suitable for high-reliability applications. Screw termination (521844-1) allows field adjustment and rework capability. Assembly process infrastructure and maintenance requirements should guide this selection.
