Substitute Part Grouping Explanation

Substitute parts for the 91486-542 are identified based on electrical and mechanical compatibility within the rectangular connector category. The primary substitution criteria are:

Critical Parameters for Substitution:

Connector type (Plug)
Number of positions (8)
Contact type (Female Socket)
Mounting type (Free Hanging In-Line)
Contact termination method (Crimp)
Fastening mechanism (Latch Lock)
Row configuration (2 rows)

Direct Manufacturer Substitute: The 91486-542LF maintains identical electrical and mechanical specifications to the main part while offering active product status and RoHS compliance. This part represents a direct functional replacement with updated manufacturing standards.

Parametric Equivalent: The TE Connectivity 936233-1 provides functional equivalence across core connector parameters including 8-position configuration, female socket contacts, crimp termination, and latch lock fastening. Variations in pitch specification notation, color, and insulation material do not preclude functional compatibility within the specified mechanical envelope.

Engineering Selection Recommendations

For New Designs and Active Production: The 91486-542LF is the preferred selection. As an active product from the original manufacturer with identical mechanical and electrical specifications, it provides direct compatibility with existing designs while meeting current RoHS compliance requirements.

For Cross-Manufacturer Compatibility: The TE Connectivity 936233-1 serves as a functional equivalent for applications where multi-source qualification is required. The operating temperature maximum of 80°C versus 85°C for the Amphenol parts represents a minor constraint applicable only to edge-case thermal environments. ROHS3 compliance status exceeds the requirements of the obsolete main part.

For Legacy System Maintenance: Original 91486-542 inventory remains available. The 91486-542LF provides seamless substitution for replacement and repair applications without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 91486-542LF be used as a direct replacement for the 91486-542?

A: Yes. The 91486-542LF maintains identical connector type, position count, pitch, row configuration, contact type, mounting method, termination type, and fastening mechanism. The primary difference is active product status and RoHS compliance.

Q: What are the mechanical compatibility constraints between the main part and substitute parts?

A: All three parts share identical 8-position, 2-row configuration with 0.100" (2.54mm) pitch and row spacing. Mechanical envelope compatibility is maintained across all substitutes for free-hanging in-line mounting applications.

Q: Does the color difference between the 91486-542 (Black) and 936233-1 (Natural) affect electrical performance?

A: Color is a cosmetic parameter that does not affect electrical or mechanical function. Selection should be based on application requirements for visual identification or aesthetic specifications.

Q: Are there temperature rating implications when substituting the 936233-1 for the 91486-542?

A: The 936233-1 operates to 80°C maximum versus 85°C for the Amphenol parts. This 5°C difference is applicable only to applications with sustained operating temperatures above 80°C. Standard industrial applications typically operate within this constraint.

Q: What is the significance of the LF suffix in the 91486-542LF part number?

A: The LF designation indicates lead-free manufacturing, reflecting RoHS compliance standards. This is a manufacturing process indicator with no impact on connector function or compatibility.

Q: Can contacts from the 91486-542 be used with substitute housing parts?

A: Contact compatibility is determined by crimp termination specifications and contact geometry. All three parts specify crimp termination and female socket contacts, supporting contact interchangeability within the LATCH-N-LOK™ and Multi-Lock series specifications.
