Molex 0444721456 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0444721456 is a shrouded vertical rectangular connector header designed for through-hole mounting in board-to-cable/wire applications. This 14-position, 2-row connector operates at 0.165" (4.20mm) pitch and features solder termination with locking ramp fastening. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0444721456 is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Position count (14 positions)
• Row configuration (2 rows)
• Mating pitch (0.165" / 4.20mm)
• Row spacing (0.165" / 4.20mm)
• Shrouding style (Shrouded - 4 Wall)
• Mounting method (Through Hole)
• Termination type (Solder)
• Fastening mechanism (Locking Ramp)

Parts meeting all these criteria are classified as direct functional equivalents. Variations in product status, packaging format, or compliance certifications do not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0444721454 is the primary direct equivalent for the obsolete Molex 0444721456. Both parts are identical in all electrical and mechanical specifications, with the key distinction being product status: the 0444721454 is active and currently in production, while the 0444721456 is obsolete. The 0444721454 maintains ROHS3 compliance and identical packaging specifications, making it a direct drop-in replacement.

The TE Connectivity 1-794489-1 serves as a manufacturer alternative from a different supplier. It maintains full mechanical and electrical compatibility across all critical parameters: 14-position, 2-row configuration at 0.165" pitch with shrouded 4-wall design, through-hole solder termination, and locking ramp fastening. The TE part offers enhanced specifications including UL94 V-0 flammability rating (versus V-2 on the Molex parts), documented operating temperature range of -55°C to 105°C, and 600VAC voltage rating. These enhancements provide additional design margin for applications requiring higher reliability or extended environmental performance. The TE part maintains RoHS compliance and unlimited moisture sensitivity level.

Selection between the Molex 0444721454 and TE Connectivity 1-794489-1 depends on supply chain strategy, cost considerations, and whether the enhanced thermal and voltage specifications of the TE part provide value for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0444721454 directly replace the obsolete Molex 0444721456?

A: Yes. The 0444721454 is electrically and mechanically identical to the 0444721456 across all specified parameters. The only difference is product status and packaging format (Tray versus unspecified). Both are ROHS3 compliant with identical contact geometry, pitch, shrouding, and termination specifications.

Q: What are the key compatibility criteria for substituting these connectors?

A: Substitution requires equivalence in connector type (Header), contact type (Male Pin), position count (14), row configuration (2 rows), mating pitch (0.165" / 4.20mm), row spacing (0.165" / 4.20mm), shrouding (Shrouded - 4 Wall), mounting method (Through Hole), termination (Solder), and fastening type (Locking Ramp). All three parts listed meet these criteria.

Q: How does the TE Connectivity 1-794489-1 differ from the Molex parts?

A: The TE part maintains full mechanical and electrical compatibility but originates from a different manufacturer (TE Connectivity AMP Connectors) and different series (AMP-DUAC versus Mini-Fit HCS 44472). The TE part offers enhanced specifications: UL94 V-0 flammability rating, documented operating temperature range (-55°C to 105°C), and 600VAC voltage rating. Contact finish thickness on the mating surface is slightly higher (118.1µin versus 100.0µin).

Q: Are there packaging considerations when switching between these parts?

A: The Molex 0444721456 packaging format is unspecified. The Molex 0444721454 is supplied in Tray packaging. The TE Connectivity 1-794489-1 packaging format is unspecified. Confirm packaging requirements with your procurement or assembly process before finalizing supplier selection.

Q: Do all three parts meet RoHS compliance requirements?

A: Yes. The Molex 0444721456 and 0444721454 are ROHS3 Compliant. The TE Connectivity 1-794489-1 is RoHS Compliant. All three parts are REACH Unaffected and carry EAR99 export classification.

Q: What is the moisture sensitivity level for these connectors?

A: All three parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control measures are required during storage, handling, or assembly.
