Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0026202121 is determined by the following critical parameters:

• Pitch - Mating: 0.156" (3.96mm) — must match exactly for mechanical compatibility
• Number of Positions: 12 — connector must accommodate identical pin count
• Number of Rows: 1 — single-row configuration is required
• Connector Type: Header — must be a header connector, not a receptacle
• Contact Type: Male Pin — pin gender must remain consistent
• Mounting Type: Through Hole — PCB mounting method must be identical
• Termination: Solder — solder termination is required for board attachment
• Contact Shape: Circular — pin geometry must be circular

The TE Connectivity AMP Connectors part number 1-640384-2 meets all critical substitution criteria. Both connectors share identical pitch, position count, row configuration, connector type, contact type, mounting method, and termination approach. Both feature circular male pins suitable for through-hole solder attachment.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0026202121 and TE Connectivity 1-640384-2 are active products with full regulatory compliance. The Molex connector carries UL94 V-2 flammability rating and ROHS3 compliance. The TE Connectivity substitute offers UL94 V-0 flammability rating, which represents a higher fire-safety standard, and maintains RoHS compliance. Both connectors are MSL 1 rated, indicating unlimited shelf life under standard storage conditions.

Selection between these parts should be based on application-specific requirements. The TE Connectivity 1-640384-2 is suitable where enhanced flammability performance is required. The Molex 0026202121 remains the primary choice where original specification compliance is mandated. Both parts are suitable for general purpose, industrial, automotive, medical, and telecommunications applications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-640384-2 be used as a direct replacement for the Molex 0026202121?

A: Yes. Both connectors share identical pitch (0.156"), position count (12), row configuration (1), connector type (header), contact type (male pin), mounting method (through hole), and termination (solder). Mechanical and electrical compatibility is established.

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

A: The primary differences are contact length specifications and insulation material composition. The Molex connector features polyamide (PA) nylon insulation, while the TE Connectivity connector uses thermoplastic glass-filled insulation. The TE Connectivity part also provides UL94 V-0 flammability rating versus the Molex UL94 V-2 rating. Operating temperature range is specified for the TE Connectivity part (-55°C to 105°C) but not provided for the Molex connector.

Q: Are there any packaging or inventory considerations?

A: Both connectors are supplied in bulk packaging. The Molex 0026202121 has 1130 units in stock, while the TE Connectivity 1-640384-2 has 2013 units available. Both are active products with established supply chains.

Q: Do both connectors meet RoHS requirements?

A: Yes. The Molex 0026202121 is ROHS3 compliant, and the TE Connectivity 1-640384-2 is RoHS compliant. Both meet current environmental and hazardous substance restrictions.

Q: What applications are these connectors suitable for?

A: The Molex connector is specified for automotive, general purpose, industrial, medical, and telecommunications applications. The TE Connectivity connector is specified for general purpose and industrial applications. Verify application compatibility based on your specific use case requirements.
