Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0444745000 is determined by strict alignment of the following critical parameters:

• Connector Position and Pitch: 14 positions with 0.165" (4.20mm) mating pitch and row spacing
• Physical Configuration: 2-row shrouded header with 4-wall shrouding
• Mounting and Termination: Through-hole solder termination with latch holder fastening
• Contact Specifications: Male pin contacts with tin plating and square contact shape
• Insulation Material: Polyamide (PA66) or equivalent nylon-based insulation
• Mechanical Dimensions: Insulation height of 0.555" (14.10mm) and post length of 0.138" (4.60mm)
• Compliance: ROHS3 compliance and UL94 V-0 flammability rating

The substitute parts identified below meet these core electrical and mechanical requirements, enabling direct functional replacement in applications originally designed for the 0444745000.

Parameter Comparison

Engineering Selection Recommendations

Molex 0015246142 is the primary recommended substitute. This part maintains active product status, ensuring long-term availability and supply chain continuity. It shares identical mechanical and electrical specifications with the original 0444745000, including 14-position configuration, 0.165" pitch, through-hole solder termination, and UL94 V-0 flammability rating. Both parts are ROHS3 compliant with MSL 1 rating. The 0015246142 belongs to the Mini-Fit BMI 42440 series and includes enhanced features such as blind mating and board lock functionality. Contact material differs (brass versus copper alloy), but this does not affect functional compatibility for standard applications.

TE Connectivity 1-1586585-4 serves as an alternative substitute from a different manufacturer. This VAL-U-LOK series connector maintains the same 14-position, 0.165" pitch configuration and through-hole solder termination. However, this part carries obsolete product status, limiting its suitability for new designs. The material flammability rating is UL94 V-2 rather than V-0, which may restrict use in applications requiring higher flame resistance. The part provides specified electrical ratings (9A current, 600VAC voltage) and operating temperature range (-40°C to 105°C), offering additional performance documentation compared to the original part.

For new designs and long-term system support, the Molex 0015246142 is the preferred choice due to active status and full specification alignment.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0015246142 be used as a direct replacement for the 0444745000?

A: Yes. Both connectors share identical mechanical dimensions, pitch specifications, mounting type, and termination method. The 0015246142 is functionally equivalent and maintains ROHS3 compliance and MSL 1 rating. The primary difference is enhanced features (blind mating, board lock) and active product status, making it suitable for direct substitution.

Q: What is the significance of the contact material difference between the 0444745000 and its substitutes?

A: The original part uses copper alloy contacts, while the 0015246142 uses brass and the TE Connectivity part uses brass alloy. All three materials provide adequate electrical conductivity and corrosion resistance for standard connector applications. The tin plating on all mating surfaces ensures consistent contact performance. Material selection does not affect functional compatibility in typical board-to-board or cable applications.

Q: Why is the TE Connectivity 1-1586585-4 listed as obsolete?

A: The VAL-U-LOK series connector carries obsolete product status, indicating it is no longer in active production. While it meets the core electrical and mechanical requirements for substitution, its obsolete status limits availability and supply chain reliability. For new designs, the active Molex 0015246142 is the recommended choice.

Q: Does the UL94 V-2 rating of the TE Connectivity part affect its suitability?

A: The TE Connectivity 1-1586585-4 carries a UL94 V-2 flammability rating, compared to UL94 V-0 for both the original 0444745000 and the Molex 0015246142. Applications requiring UL94 V-0 compliance must use the Molex 0015246142. For applications with UL94 V-2 acceptance, the TE Connectivity part is functionally compatible.

Q: Are there packaging differences between these connectors?

A: The Molex 0015246142 is supplied in tray packaging. The original 0444745000 and TE Connectivity 1-1586585-4 do not specify packaging format in the provided data. Packaging differences do not affect connector functionality but may influence procurement and handling procedures.

Q: What is the significance of the contact finish thickness variation?

A: The original 0444745000 and Molex 0015246142 both specify 100.0µin (2.54µm) tin plating thickness on mating contacts. The TE Connectivity 1-1586585-4 specifies 39.4µin (1.00µm). Both thicknesses provide adequate corrosion protection and electrical performance for standard applications. The thicker plating on the Molex parts may offer extended service life in high-cycle mating environments.

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

A: Yes, all three connectors share identical footprint specifications: 14 positions, 0.165" (4.20mm) pitch, 0.165" row spacing, and 0.555" (14.10mm) insulation height. PCB designs accommodating the original 0444745000 will accept any of the substitute parts without modification.
