Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 71920-404 is determined by strict equivalence across the following parameters:

• Connector type: Receptacle, bottom or top entry
• Number of positions: 4
• Pitch specification: 0.100" (2.54mm)
• Contact type: Female socket
• Mounting method: Through hole
• Termination method: Solder
• Fastening mechanism: Push-pull
• Insulation material: Thermoplastic, glass filled
• Flammability rating: UL94 V-0
• Series family: Dubox™

The 71920-404LF meets all these criteria and qualifies as a direct substitute. The primary distinction between these parts is the contact finish specification and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The 71920-404LF is the appropriate substitute for the obsolete 71920-404. Both connectors share identical mechanical and electrical interface specifications, ensuring direct compatibility in board-to-board applications.

The 71920-404LF offers the additional advantage of active product status, ensuring continued availability and supply chain reliability. The shift from tin-lead to tin contact finish in the 71920-404LF aligns with RoHS compliance requirements, making it suitable for applications subject to environmental regulations.

Selection between these parts should be based on regulatory requirements and supply chain considerations. The 71920-404LF is recommended for new designs and production runs requiring RoHS compliance. The 71920-404 remains functionally equivalent for legacy systems where lead-based finishes are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the 71920-404LF directly replace the 71920-404 in existing designs?

A: Yes. Both connectors maintain identical mechanical dimensions, pitch spacing, contact geometry, and mounting specifications. The connectors are mechanically and electrically interchangeable in board-to-board applications.

Q: What is the significance of the contact finish difference between these parts?

A: The 71920-404 uses tin-lead finish, while the 71920-404LF uses tin finish. This difference reflects RoHS compliance status. The tin finish in the 71920-404LF eliminates lead content, meeting environmental regulations. Both finishes provide equivalent electrical performance and contact reliability.

Q: Why is the 71920-404 listed as obsolete?

A: The obsolete status reflects the manufacturer's discontinuation of the tin-lead variant. The 71920-404LF represents the active production equivalent, incorporating modern compliance standards.

Q: Are there packaging differences between these parts?

A: The 71920-404 packaging specification is not provided. The 71920-404LF is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: What applications are these connectors suitable for?

A: Both connectors are specified for automotive, general purpose, industrial, and telecommunications applications. The UL94 V-0 flammability rating and through-hole construction support these application categories.
