• Gender: Female, Receptacle

Mechanical Compatibility Parameters:

• Mounting type: Free Hanging (In-Line)
• Stacking direction: Top to Bottom
• Housing style: Receptacle housing

Regulatory & Environmental Parameters:

• RoHS compliance status
• Moisture Sensitivity Level (MSL): 1
• ECCN classification: EAR99
• HTSUS code: 8536.69.8000

Parts meeting all specified parameters within this grouping are classified as direct substitutes. The substitute part 1-520987-6 satisfies all critical electrical, mechanical, and regulatory requirements for direct replacement.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1-520987-6 is a direct functional equivalent to the obsolete 520987-6. Both components share identical electrical specifications, mechanical dimensions, and mounting characteristics. The substitute part maintains active product status with TE Connectivity AMP Connectors, ensuring ongoing availability and supply chain continuity.

Both parts satisfy RoHS compliance requirements and carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8536.69.8000). The Moisture Sensitivity Level of 1 (Unlimited) indicates no special handling or storage requirements for either component.

The primary distinction between the two parts is product lifecycle status: the original 520987-6 is obsolete, while 1-520987-6 is actively manufactured and supported. For new designs and ongoing procurement, 1-520987-6 is the appropriate selection. For legacy system maintenance requiring the original part number, 1-520987-6 provides complete functional interchangeability.

Frequently Asked Questions (FAQ)

Q: Can 1-520987-6 be used as a direct replacement for 520987-6 in existing assemblies?

A: Yes. Both parts are identical in electrical performance, mechanical dimensions, terminal configuration, and mounting specifications. The 1-520987-6 is a direct substitute with no circuit or mechanical modifications required.

Q: What is the difference between 520987-6 and 1-520987-6?

A: The primary difference is product status. The 520987-6 is obsolete, while 1-520987-6 is an active product. Both components are manufactured by TE Connectivity AMP Connectors and share identical specifications for terminal size (0.250"), position count (4), gender (female receptacle), and mounting type (free hanging, in-line).

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. Both parts conform to the same electrical and mechanical standards, carry identical RoHS compliance certifications, and share the same ECCN and HTSUS classifications. The MSL rating of 1 (Unlimited) applies to both components.

Q: Why is the original part number obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand and product lifecycle management. The substitute part 1-520987-6 provides continued access to equivalent functionality through an active product offering.

Q: Are contacts included with these housing connectors?

A: No. Both the 520987-6 and 1-520987-6 are housing components only. Contacts must be sourced separately and are compatible with 0.250" (6.35mm) quick connect terminal specifications.

Q: What is the stacking direction specification?

A: Both parts feature top-to-bottom stacking direction, which defines the orientation in which multiple connector positions are arranged within the housing assembly.
