TE Connectivity AMP Connectors 4-647648-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 4-647648-2 is an active rectangular connector header designed for through-hole mounting applications. This 12-position connector operates at 0.156" (3.96mm) pitch and is classified as a shrouded, single-wall header with male pin contacts. The connector is manufactured from copper alloy with tin plating and polyamide nylon insulation, rated for -55°C to 105°C operation and 600VAC voltage applications.

Substitute parts are necessary when original inventory is unavailable, when alternative sourcing reduces lead times, or when equivalent connectors from different manufacturers meet identical electrical and mechanical specifications for board-to-cable or board-to-board interconnection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers is determined by strict equivalence across the following critical parameters:

Primary Matching Criteria:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (12)
• Number of rows (1)
• Pitch - mating (0.156" / 3.96mm)
• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 1 Wall)
• Termination method (Solder)
• Fastening type (Friction Lock)

Secondary Compatibility Factors:

• Operating temperature range capability
• Voltage rating
• Material flammability rating (UL94 compliance)
• RoHS compliance status
• Moisture sensitivity level

The substitute parts listed below meet all primary matching criteria and maintain compatibility with the original TE Connectivity 4-647648-2 connector in board-to-cable and board-to-board applications. Variations in contact geometry (circular versus square), contact finish composition, insulation material composition, and specific dimensional tolerances are noted in the parameter comparison table and do not preclude functional substitution when electrical and mechanical interface requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 4-647648-2 (Primary Part)

The TE Connectivity 4-647648-2 remains the primary specification when original part sourcing is available. This connector carries UL94 V-0 flammability rating and RoHS compliance certification. The circular contact geometry and copper alloy material composition are specified for the original design.

Molex 0026604120 (Substitute)

The Molex 0026604120 is a direct functional substitute meeting all primary matching criteria. This part maintains UL94 V-0 flammability rating and ROHS3 compliance. The connector features square contact geometry and polyester glass-filled insulation material. The contact post length is 0.140" (3.56mm) compared to the original 0.125" (3.18mm), resulting in a total contact length of 0.720" (18.29mm). The insulation height is 0.446" (11.33mm), which is lower than the original 0.545" (13.84mm). These dimensional variations are within acceptable tolerance for board-to-cable and board-to-board interconnection applications where mating interface geometry is standardized by the 0.156" pitch specification.

Molex 1718131012 (Substitute)

The Molex 1718131012 is a functional substitute with the following considerations. This part carries UL94 V-2 flammability rating, which is lower than the original UL94 V-0 specification. The connector features gold-plated mating contacts on brass material, compared to tin-plated copper alloy in the original design. The contact post length is 0.093" (2.35mm), resulting in a total contact length of 0.671" (17.05mm). The insulation height is 0.446" (11.33mm). Selection of this part is appropriate when gold-plated contact surfaces are required for enhanced corrosion resistance or when the lower flammability rating is acceptable for the application environment.

All three connectors maintain identical pitch, position count, mounting type, shrouding configuration, and fastening mechanism. All three are rated for MSL 1 (Unlimited) moisture sensitivity and carry active product status.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0026604120 be used as a direct replacement for the TE Connectivity 4-647648-2?

A: Yes. Both connectors share identical pitch (0.156"), position count (12), row configuration (1), mounting type (through hole), shrouding (shrouded 1-wall), termination method (solder), and fastening type (friction lock). The square contact geometry of the Molex part does not affect compatibility with standard mating connectors designed for 0.156" pitch headers. Both maintain UL94 V-0 flammability rating and RoHS compliance.

Q: What are the dimensional differences between these three connectors?

A: The primary dimensional variations are contact post length and overall contact length. The TE Connectivity 4-647648-2 has a contact post of 0.125" (3.18mm) and overall contact length of 0.700" (17.78mm). The Molex 0026604120 has a contact post of 0.140" (3.56mm) and overall contact length of 0.720" (18.29mm). The Molex 1718131012 has a contact post of 0.093" (2.35mm) and overall contact length of 0.671" (17.05mm). Insulation height also varies: TE Connectivity at 0.545" (13.84mm) versus both Molex parts at 0.446" (11.33mm). These variations are accommodated by standard PCB design tolerances for through-hole mounting.

Q: Does the contact finish difference affect substitution?

A: Contact finish differences are noted but do not preclude substitution. The TE Connectivity 4-647648-2 and Molex 0026604120 both use tin plating on mating contacts. The Molex 1718131012 uses gold plating (15.0µin thickness) on brass material. Gold plating provides enhanced corrosion resistance and is suitable for applications requiring extended shelf life or exposure to corrosive environments. Tin plating is standard for general industrial applications. Selection between tin and gold finishes depends on application requirements, not connector compatibility.

Q: Is the Molex 1718131012 suitable for high-temperature applications?

A: Operating temperature range specifications are not provided in the technical data for either Molex substitute. The TE Connectivity 4-647648-2 is rated for -55°C to 105°C operation. When operating temperature range is a critical design parameter, the original TE Connectivity part or the Molex 0026604120 should be selected based on available temperature specifications.

Q: What is the significance of the UL94 V-2 rating on the Molex 1718131012?

A: The Molex 1718131012 carries UL94 V-2 flammability rating, compared to UL94 V-0 on the TE Connectivity 4-647648-2 and Molex 0026604120. UL94 V-0 represents higher flame resistance than V-2. Selection of the Molex 1718131012 is appropriate when the application environment permits V-2 rating or when gold-plated contacts are specifically required. Applications with strict flammability requirements should specify the V-0 rated connectors.

Q: Are all three connectors RoHS compliant?

A: Yes. The TE Connectivity 4-647648-2 is RoHS Compliant. Both Molex parts (0026604120 and 1718131012) are ROHS3 Compliant. Both Molex parts carry REACH Unaffected status, while the TE Connectivity part lists REACH status as Vendor Undefined. All three connectors are suitable for applications requiring RoHS compliance.

Q: What is the inventory availability for each part?

A: The TE Connectivity 4-647648-2 has 988 pieces in stock. The Molex 0026604120 has 11,140 pieces in stock. The Molex 1718131012 has 4,675 pieces in stock. Substitute parts offer significantly higher inventory availability for applications requiring immediate delivery or high-volume procurement.
