Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0026654020 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: 2
• Number of Rows: 1
• Pitch - Mating: 0.156" (3.96mm)
• Mounting Type: Through Hole
• Shrouding: Shrouded - 1 Wall
• Termination: Solder
• Fastening Type: Friction Lock
• Contact Shape: Square
• Material Flammability Rating: UL94 V-0

Identified Substitutes:

• TE Connectivity AMP Connectors 3-644611-2 (MTA-156 Series)
• TE Connectivity AMP Connectors 3-644615-2 (MTA-156 Series)

Both substitute parts satisfy all primary matching criteria and are classified as Active products with RoHS3 compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and satisfy RoHS3 compliance requirements with MSL 1 rating, indicating no moisture sensitivity constraints during storage or handling. The Molex 0026654020 features gold-plated mating contacts with brass material composition, while both TE Connectivity substitutes employ tin-plated contacts with copper alloy material. The TE Connectivity parts provide specified operating temperature range (-55°C ~ 105°C) and voltage rating (600VAC), whereas the Molex part does not include these electrical specifications in the provided data.

Dimensional variations exist between the main part and substitutes: the Molex part exhibits a contact post length of 0.140" (4.66mm) and insulation height of 0.446" (11.33mm), while TE Connectivity parts specify 0.125" (3.18mm) post length and 0.545" (13.84mm) insulation height. These dimensional differences require verification against PCB design specifications and mating connector geometry to ensure proper engagement and clearance.

The TE Connectivity 3-644615-2 includes a Board Guide feature, matching the Molex part's board guide specification, whereas the 3-644611-2 does not specify this feature. Selection between the two TE Connectivity options should prioritize the 3-644615-2 when board guide functionality is required for assembly alignment.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine substitution compatibility for the Molex 0026654020?

A: Substitution compatibility is determined by matching connector type (Header), contact type (Male Pin), number of positions (2), number of rows (1), mating pitch (0.156" / 3.96mm), mounting type (Through Hole), shrouding configuration (Shrouded - 1 Wall), termination method (Solder), fastening type (Friction Lock), and contact shape (Square). All identified substitutes satisfy these parameters.

Q: Are there dimensional differences between the Molex part and TE Connectivity substitutes?

A: Yes. The Molex 0026654020 specifies a contact post length of 0.140" (4.66mm) and insulation height of 0.446" (11.33mm). Both TE Connectivity substitutes specify a contact post length of 0.125" (3.18mm) and insulation height of 0.545" (13.84mm). These differences require verification against mating connector specifications and PCB design parameters.

Q: What is the difference between the two TE Connectivity substitute options?

A: Both TE Connectivity 3-644611-2 and 3-644615-2 are functionally equivalent MTA-156 series headers with identical electrical and mechanical specifications. The primary distinction is that the 3-644615-2 includes a Board Guide feature, matching the Molex part's board guide specification. The 3-644611-2 does not specify this feature.

Q: Do the contact finish materials affect substitution suitability?

A: Contact finish materials differ between parts: the Molex part features gold-plated mating contacts, while both TE Connectivity substitutes employ tin-plated mating contacts. Material compatibility with mating connectors and application-specific corrosion resistance requirements should be evaluated during design verification.

Q: Are all parts RoHS3 compliant and suitable for regulated applications?

A: Yes. The Molex 0026654020 and both TE Connectivity substitutes are RoHS3 compliant with UL94 V-0 flammability rating and MSL 1 moisture sensitivity level, indicating suitability for general purpose, industrial, and regulated applications without moisture sensitivity constraints.
