Key Parameters

Substitute Part Grouping Explanation

The 51416-002LF serves as a direct functional equivalent to the 51416-002. Substitution is valid based on identical electrical and mechanical parameters: both connectors maintain the same 26-position configuration, 0.100" pitch, 4-row layout, blade power connector style, and solder termination. The contact finish specifications, flammability rating, operating temperature range, and moisture sensitivity level are identical across both parts. The primary distinction is product status: the 51416-002 is obsolete, while the 51416-002LF is active and RoHS compliant, making it the recommended selection for new designs and ongoing production requirements.

Parameter Comparison

Engineering Selection Recommendations

The 51416-002LF is the appropriate selection for all applications currently using or specifying the 51416-002. Both connectors are electrically and mechanically identical, with identical contact configurations, pitch, mounting geometry, and thermal operating range. The 51416-002LF offers the advantage of active product status and RoHS compliance, meeting current regulatory requirements for new designs and production environments. For legacy systems currently deployed with the 51416-002, the 51416-002LF provides direct compatibility without design modification. The transition from the obsolete 51416-002 to the active 51416-002LF is supported by identical mechanical and electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can the 51416-002LF be used as a direct replacement for the 51416-002?

A: Yes. Both connectors share identical electrical and mechanical specifications, including 26-position configuration, 0.100" pitch, 4-row layout, blade power connector style, contact finish, and operating temperature range. The 51416-002LF is the active equivalent.

Q: What is the difference between the 51416-002 and 51416-002LF?

A: The primary differences are product status and compliance. The 51416-002 is obsolete and RoHS non-compliant, while the 51416-002LF is active and RoHS compliant. All electrical and mechanical parameters are identical.

Q: Are there packaging differences between these parts?

A: The 51416-002LF is supplied in bulk packaging, while the 51416-002 packaging specification was not provided. Both parts are functionally equivalent for board-level integration.

Q: What certifications apply to both connectors?

A: Both the 51416-002 and 51416-002LF meet UL94 V-0 material flammability requirements and operate across the -20°C to 105°C temperature range. The 51416-002LF additionally meets RoHS compliance requirements.

Q: Can these connectors be used interchangeably in existing designs?

A: Yes. The identical mechanical mounting (board edge, through-hole, right-angle), pitch spacing, and contact configuration ensure direct interchangeability without PCB redesign or layout modification.
