Molex 0444741421 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0444741421 is a shrouded vertical header connector from the Mini-Fit HCS 44474 series, designed for through-hole board-to-board or cable applications. This connector features 14 positions arranged in 2 rows with 0.165" (4.20mm) pitch and is widely used in automotive, industrial, medical, and telecommunications applications. The part is currently active in production. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the original part becomes unavailable or when design requirements permit alternative qualified sources.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0444741421 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Matching Criteria:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (14)
• Number of rows (2)
• Pitch - mating (0.165" / 4.20mm)
• Row spacing - mating (0.165" / 4.20mm)
• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)

Secondary Compatibility Factors:

• Insulation material composition (Polyamide/Nylon family)
• Contact finish (Tin plating)
• Insulation height (0.555" / 14.10mm)
• Contact post length (0.138" / 4.60mm)

The TE Connectivity AMP Connectors part 1-1586585-4 from the VAL-U-LOK series meets all primary matching criteria and maintains compatibility across secondary factors, qualifying it as a direct substitute despite differences in contact material composition (Brass Alloy vs. Copper Alloy) and flammability rating (UL94 V-2 vs. UL94 V-0).

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 1-1586585-4 qualifies as a functional substitute for the Molex 0444741421 based on matching mechanical and electrical interface parameters. Both parts are ROHS3 compliant and maintain MSL 1 (Unlimited) moisture sensitivity ratings.

Product Status Consideration: The Molex 0444741421 maintains active production status, while the TE Connectivity 1-1586585-4 is classified as obsolete. Selection of the substitute should be based on application requirements and supply chain availability rather than product lifecycle status alone.

Compliance Alignment: Both parts comply with ROHS3 requirements and carry EAR99 ECCN classification. The difference in material flammability rating (UL94 V-0 for Molex versus UL94 V-2 for TE Connectivity) must be evaluated against specific application requirements, particularly in applications with stringent flame-resistance specifications.

Contact Material Difference: The Molex part uses Copper Alloy contacts while the TE Connectivity substitute uses Brass Alloy contacts. Both materials are suitable for tin-plated mating surfaces and general-purpose through-hole applications. This difference does not affect mechanical interchangeability but may influence electrical performance characteristics in specific high-current or high-frequency applications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-1586585-4 be used as a direct replacement for the Molex 0444741421 in new designs?

A: Yes, from a mechanical and electrical interface perspective. Both connectors share identical pitch (0.165" / 4.20mm), row configuration (2 rows, 14 positions), mounting type (through-hole), and shrouding design (4-wall shrouded). However, the difference in flammability rating (UL94 V-2 vs. V-0) must be evaluated against application-specific requirements before implementation.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Contact material composition (Copper Alloy vs. Brass Alloy), (2) Material flammability rating (UL94 V-0 vs. UL94 V-2), (3) Contact finish thickness (100.0µin vs. 39.4µin), and (4) Product status (Active vs. Obsolete). All other mechanical and electrical parameters align.

Q: Are the pin configurations identical between these connectors?

A: Yes. Both connectors feature 14 positions in a 2-row configuration with 0.165" (4.20mm) pitch and row spacing. The insulation height (0.555" / 14.10mm) and contact post length (0.138" / 4.60mm) are identical, ensuring mechanical compatibility in board layouts.

Q: Does the difference in contact material affect performance?

A: Contact material composition (Copper Alloy vs. Brass Alloy) does not affect mechanical interchangeability or basic electrical performance in standard through-hole applications. Both materials support tin plating and are suitable for general-purpose, industrial, and automotive applications. Specific high-current or specialized electrical performance requirements should be evaluated against the electrical ratings provided for each part.

Q: What should be considered when selecting between these parts?

A: Selection should be based on: (1) Application flammability requirements (UL94 V-0 vs. V-2), (2) Supply chain availability and lead times, (3) Operating temperature range requirements (-40°C ~ 105°C for the TE Connectivity part), (4) Current and voltage rating requirements (9A / 600VAC for the TE Connectivity part), and (5) Design compliance with RoHS3 and REACH regulations (both parts compliant).
