Substitution of the 647609-4 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Pitch spacing: 0.100" (2.54mm)
• Number of positions: 4
• Number of rows: 1
• Voltage rating: 250VAC
• Operating temperature range: -55°C ~ 105°C

Mechanical Parameters:

• Connector type: Header
• Contact type: Male Pin
• Mounting type: Through Hole
• Termination method: Solder
• Shrouding configuration: Shrouded - 1 Wall
• Fastening type: Friction Lock

Material & Compliance Parameters:

• Insulation material: Polybutylene Terephthalate (PBT), Glass Filled
• Material flammability rating: UL94 V-0
• RoHS compliance status
• Moisture sensitivity level: 1 (Unlimited)

The substitute part 3-647609-4 maintains equivalence across all critical electrical and mechanical parameters. The primary distinction between the main part and the substitute is the product status (obsolete versus active) and contact finish specification (Tin-Lead versus Tin).

Parameter Comparison

Engineering Selection Recommendations

The 3-647609-4 is the direct substitute for the obsolete 647609-4. Both parts belong to the TE Connectivity AMP Connectors MTA-100 series and maintain identical electrical and mechanical specifications across all critical parameters.

Product Status Consideration: The 647609-4 is classified as obsolete, while the 3-647609-4 is active. For new designs, ongoing production, and long-term component availability, the 3-647609-4 is the appropriate selection.

Compliance Status: Both parts maintain UL94 V-0 flammability rating and are compliant with RoHS regulations. The 3-647609-4 carries ROHS3 compliance, representing the current regulatory standard. Both parts are REACH Unaffected and classified under ECCN EAR99.

Contact Finish Specification: The primary technical distinction is the contact finish. The 647609-4 specifies Tin-Lead finish on both mating and post contacts, while the 3-647609-4 specifies Tin finish. Both finishes are compatible with standard solder termination processes and provide equivalent electrical performance within the specified operating parameters.

Inventory and Availability: The 3-647609-4 maintains significantly higher inventory availability (7611 pieces) compared to the 647609-4 (1054 pieces), supporting sustained production requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3-647609-4 directly replace the 647609-4 in existing applications?

A: Yes. The 3-647609-4 maintains identical electrical and mechanical specifications across all critical parameters including pitch spacing (0.100"), position count (4), voltage rating (250VAC), operating temperature range (-55°C to 105°C), mounting type (through hole), and termination method (solder). Both parts are from the MTA-100 series and share the same base product number (647609).

Q: What is the significance of the contact finish difference between Tin-Lead and Tin?

A: Both Tin-Lead and Tin finishes are compatible with standard solder termination processes and provide equivalent electrical performance. The Tin finish on the 3-647609-4 reflects current manufacturing standards and regulatory compliance with lead reduction initiatives. The functional performance in board-to-cable and board-to-wire applications remains equivalent.

Q: Are there any packaging differences between the two parts?

A: The 647609-4 packaging specification is not provided in the available data. The 3-647609-4 is supplied in bulk packaging. For specific packaging requirements, consult the detailed product documentation or contact the manufacturer directly.

Q: Does the RoHS compliance difference (RoHS versus ROHS3) affect substitution?

A: No. Both parts are RoHS compliant. The 3-647609-4 carries ROHS3 compliance, which represents the current regulatory standard. This does not create incompatibility; rather, it indicates the 3-647609-4 meets the most current regulatory requirements.

Q: What is the moisture sensitivity level, and does it affect handling?

A: Both parts carry Moisture Sensitivity Level (MSL) 1, classified as Unlimited. This indicates the components do not require special moisture control during storage, handling, or assembly, simplifying logistics and manufacturing processes.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the 647609-4 and 3-647609-4 operate across the identical temperature range of -55°C to 105°C, ensuring thermal compatibility in equivalent applications.

Q: What applications are these connectors designed for?

A: Both parts are classified for general-purpose applications. The header connector design with friction lock fastening and shrouded 1-wall configuration supports standard board-to-cable and board-to-wire interconnect requirements in industrial, commercial, and consumer electronics applications.
