Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1-520527-1 is determined by strict equivalence across the following critical parameters:

Connector Architecture: SDL plug configuration with 4-position contact arrangement Electrical Performance: 30V voltage rating and 1.5A current capacity Mechanical Interface: Ribbon cable compatibility with 26-28 AWG wire gauge specification Termination Method: Crimp-style contact termination Physical Dimensions: 0.890" (22.61mm) length Shielding Configuration: Shielded design with brass shield material Contact Metallurgy: Gold-plated copper alloy contacts Housing Composition: Polycarbonate material with keyed feature

The substitute part 1-1761187-1 maintains identical specifications across all these parameters, establishing direct functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The 1-1761187-1 serves as the direct substitute for the obsolete 1-520527-1 based on complete electrical and mechanical parameter equivalence within the TE Connectivity AMP Connectors Series 36 product line.

Product Status Consideration: The 1-520527-1 is classified as obsolete, while the 1-1761187-1 maintains active product status with confirmed inventory availability (644 pieces in stock). This status differential ensures continued supply chain access and manufacturer support for the substitute part.

Compliance Advantage: The 1-1761187-1 achieves ROHS3 compliance, whereas the 1-520527-1 is RoHS non-compliant. Selection of the substitute part aligns with current regulatory requirements for electronic component procurement in regulated markets.

Functional Interchangeability: Both parts operate identically within the specified electrical envelope (30V, 1.5A) and maintain identical mechanical interfaces for ribbon cable termination at 26-28 AWG. The keyed SDL plug configuration, shielded design, and crimp termination method are preserved across both parts.

Frequently Asked Questions (FAQ)

Q: Are the 1-520527-1 and 1-1761187-1 mechanically interchangeable?

A: Yes. Both connectors feature identical SDL plug configurations with 4-position keyed design, 0.890" (22.61mm) length, and ribbon cable interface specifications. Mechanical compatibility is complete.

Q: What electrical parameters must match for substitution?

A: The voltage rating (30V), current rating (1.5A), wire gauge specification (26-28 AWG), and contact metallurgy (gold-plated copper alloy) must remain constant. Both parts satisfy these requirements identically.

Q: Does the RoHS compliance difference affect substitution eligibility?

A: RoHS compliance status does not affect electrical or mechanical interchangeability. However, the ROHS3 compliance of the 1-1761187-1 provides regulatory advantage for new designs and procurement in jurisdictions with RoHS requirements.

Q: What is the significance of the product status difference?

A: The 1-520527-1 is obsolete and subject to limited availability. The 1-1761187-1 is active with confirmed inventory, ensuring reliable supply for production and repair applications.

Q: Are the shielding specifications identical?

A: Yes. Both parts feature brass shield material with shielded connector design, maintaining identical electromagnetic interference protection characteristics.

Q: What packaging differences exist between these parts?

A: The 1-520527-1 packaging specification is not provided. The 1-1761187-1 is supplied in bulk packaging. Verify packaging requirements for your specific application workflow.

Q: Can the 1-1761187-1 be used in existing designs specified for the 1-520527-1?

A: Yes. Complete parameter equivalence across connector type, electrical ratings, mechanical dimensions, and termination method establishes direct substitution capability for existing designs.
