Key Parameters

Substitute Part Grouping Explanation

Substitution for the 72454-034 is determined by strict equivalence across the following critical parameters:

• Connector type, contact type, and gender (Header, Male Pin)
• Position count and row configuration (34 positions, 2 rows)
• Pitch specifications (0.100" mating pitch, 0.100" row spacing)
• Mounting technology (Surface Mount)
• Shrouding design (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening mechanism (Push-Pull)
• Contact geometry and material (Square, Phosphor Bronze)
• Contact finish specifications (Gold GXT™ mating, Tin post)
• Electrical ratings (1A current, operating temperature -65°C ~ 105°C)
• Safety certifications (UL94 V-0)

The substitute part 72454-034LF maintains identical electrical and mechanical specifications while differing in product status (Active vs. Obsolete) and regulatory compliance posture (RoHS Compliant vs. non-compliant).

Parameter Comparison

Engineering Selection Recommendations

The 72454-034LF serves as the direct substitute for the obsolete 72454-034. Both parts are manufactured by Amphenol ICC within the Quickie™ series and maintain identical electrical and mechanical specifications across all critical parameters.

The primary distinction between these parts is regulatory and availability status. The 72454-034LF is classified as Active product status with RoHS Compliant certification, whereas the 72454-034 is Obsolete and RoHS non-compliant. For new designs or ongoing production requiring compliance with current environmental regulations, the 72454-034LF is the appropriate selection. The 72454-034LF is supplied in Tray packaging, which is standard for surface mount components in production environments.

Both parts maintain identical performance characteristics including 1A current rating, -65°C to 105°C operating temperature range, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can the 72454-034LF be used as a direct replacement for the 72454-034?

A: Yes. The 72454-034LF is electrically and mechanically equivalent to the 72454-034. All connector specifications including position count, pitch, contact geometry, termination method, and electrical ratings are identical.

Q: What is the difference between the 72454-034 and 72454-034LF?

A: The primary differences are product status and regulatory compliance. The 72454-034 is Obsolete and RoHS non-compliant, while the 72454-034LF is Active and RoHS Compliant. The 72454-034LF is supplied in Tray packaging. All electrical and mechanical parameters are identical.

Q: Why is the 72454-034 marked as Obsolete?

A: The 72454-034 has been superseded by the 72454-034LF. Amphenol ICC maintains the 72454-034LF as the current production part within the Quickie™ series for this connector configuration.

Q: Are there any compatibility concerns when substituting the 72454-034LF for the 72454-034?

A: No compatibility concerns exist. The parts are mechanically and electrically interchangeable. PCB footprints, mating connector requirements, and electrical performance remain unchanged.

Q: What is the significance of the "LF" suffix in the 72454-034LF part number?

A: The "LF" suffix indicates Lead-Free composition, which aligns with RoHS compliance requirements. This reflects the shift in manufacturing standards toward lead-free solder termination and materials.

Q: What packaging is available for the 72454-034LF?

A: The 72454-034LF is supplied in Tray packaging, which is standard for surface mount connector components in production and assembly environments.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the 72454-034 and 72454-034LF operate across the identical temperature range of -65°C to 105°C.
