Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0022053141 with the TE Connectivity 1-640457-4 is based on the following critical parameters that must align for functional equivalence:

Mandatory Matching Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 14
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole, Right Angle
• Shrouding: Shrouded - 1 Wall
• Termination: Solder
• Fastening Type: Friction Lock
• Contact Finish - Mating: Tin
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Both parts satisfy these core electrical and mechanical requirements, enabling direct substitution in applications requiring 14-position, 2.54mm pitch right-angle headers with solder termination and friction lock fastening.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0022053141 and TE Connectivity 1-640457-4 are active products with ROHS3 compliance and identical flammability ratings (UL94 V-0). Selection between these parts should be based on:

Product Availability: The Molex 0022053141 has 2581 units in stock, while the TE Connectivity 1-640457-4 has 1066 units available. Choose based on current inventory requirements and lead time constraints.

Compliance Certification: Both parts meet ROHS3 requirements and carry EAR99 export classification. Both are classified as HTSUS 8536.69.4040 for tariff purposes.

Contact Material Variation: The Molex part uses brass contacts, while the TE Connectivity substitute uses copper alloy contacts. Both materials are tin-plated and suitable for solder termination applications.

Insulation Material Variation: The Molex part specifies polyamide (PA) nylon insulation, while the TE Connectivity part uses thermoplastic insulation. Both materials meet UL94 V-0 flammability requirements.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-640457-4 directly replace the Molex 0022053141 in existing designs?

A: Yes. Both connectors share identical pitch (2.54mm), position count (14), mounting type (through-hole right angle), shrouding configuration (1 wall), termination method (solder), and fastening mechanism (friction lock). The connectors are mechanically and electrically compatible for board-to-board and cable interconnection applications.

Q: What are the differences between these two connector models?

A: The primary differences are contact material (brass vs. copper alloy), insulation material (polyamide nylon vs. thermoplastic), and manufacturer series designation (KK254/7478 vs. MTA-100). Both parts maintain identical electrical performance characteristics and compliance certifications.

Q: Are there any operating temperature differences between these parts?

A: The TE Connectivity 1-640457-4 specifies an operating temperature range of -55°C to 105°C. The Molex 0022053141 does not provide an operating temperature specification in the available data. Verify temperature requirements against your application specifications before selection.

Q: Do both connectors support the same current and voltage ratings?

A: The TE Connectivity 1-640457-4 is rated for 250VAC with current varying by wire gauge. The Molex 0022053141 does not provide current or voltage rating specifications in the available data. Consult manufacturer datasheets for detailed electrical specifications.

Q: What is the significance of the MSL (Moisture Sensitivity Level) rating?

A: Both connectors carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These parts can be stored and handled under standard conditions without special moisture control measures.

Q: Are both parts RoHS compliant?

A: Yes. Both the Molex 0022053141 and TE Connectivity 1-640457-4 are ROHS3 compliant, meeting European Union restrictions on hazardous substances.
