Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 647050-4 is determined by strict alignment with the following core parameters:

Critical Matching Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 4
• Number of Rows: 1
• Mounting Type: Through Hole
• Termination: Solder
• Shrouding: Shrouded - 1 Wall
• Fastening Type: Friction Lock
• Operating Temperature Range: -55°C ~ 105°C
• Voltage Rating: 250VAC
• Material Flammability Rating: UL94 V-0

Two substitute parts meet these criteria:

3-647050-4 (TE Connectivity AMP Connectors): Direct manufacturer equivalent with identical electrical and mechanical specifications. This part is the active production variant of the obsolete 647050-4, differing only in contact finish composition (Tin versus Tin-Lead) and product status (Active versus Obsolete).

0022231045 (Molex): Cross-manufacturer substitute from the KK254/6373 series. This part maintains all critical parameters including pitch, position count, mounting type, and operating specifications. Minor dimensional variations exist in contact lengths and insulation height, with contact finish composition differences (Gold mating surface versus Tin-Lead).

Engineering Selection Recommendations

3-647050-4 (Primary Substitute)

The 3-647050-4 is the recommended primary substitute for the obsolete 647050-4. Both parts are manufactured by TE Connectivity and belong to the MTA-100 series. The 3-647050-4 maintains identical mechanical and electrical specifications with the exception of contact finish composition. The main part features Tin-Lead mating contact finish, while the substitute features Tin mating contact finish. Both finishes provide equivalent electrical performance and solderability characteristics.

The 3-647050-4 carries Active product status with significantly higher inventory availability (10,637 pieces in stock versus 722 pieces for the main part). This part is RoHS Compliant and carries REACH Unaffected status, providing regulatory compliance for current manufacturing standards. The transition from Tin-Lead to Tin contact finish aligns with industry-wide RoHS compliance initiatives.

0022231045 (Secondary Substitute)

The 0022231045 from Molex serves as a secondary cross-manufacturer substitute. This part maintains all critical electrical and mechanical parameters including pitch, position count, mounting type, and fastening mechanism. The part is Active status with 1,033 pieces in stock.

Minor dimensional variations exist: contact lengths are slightly longer (0.295" mating versus 0.290", and 0.140" post versus 0.135"), and insulation height is reduced (0.322" versus 0.347"). These variations remain within typical connector tolerance ranges and do not affect functional compatibility in standard applications.

The 0022231045 features Gold mating contact finish (20.0µin thickness) compared to the Tin-Lead finish of the main part. Gold plating provides enhanced corrosion resistance and contact reliability in demanding environments. The part is ROHS3 Compliant and REACH Unaffected.

Operating temperature and voltage rating specifications are not provided for the 0022231045. Design verification is required when these parameters are critical to the application.

Frequently Asked Questions (FAQ)

Q: Can the 3-647050-4 be used as a direct replacement for the 647050-4?

A: Yes. The 3-647050-4 is the active production equivalent of the obsolete 647050-4. Both parts share identical connector type, pitch, position count, mounting method, and operating specifications. The primary difference is contact finish composition (Tin versus Tin-Lead). Both finishes are suitable for solder termination and provide equivalent electrical performance. The 3-647050-4 is the recommended substitute for new designs and ongoing production.

Q: What are the differences between the TE Connectivity 3-647050-4 and the Molex 0022231045?

A: Both parts maintain the same 0.100" (2.54mm) pitch, 4-position configuration, through-hole mounting, and solder termination. Key differences include: manufacturer (TE Connectivity versus Molex), series designation (MTA-100 versus KK254/6373), contact material (Copper Alloy versus Brass), contact finish (Tin versus Gold), and minor dimensional variations in contact lengths and insulation height. The Molex part offers Gold plating for enhanced corrosion resistance.

Q: Are there packaging differences between these substitute parts?

A: Yes. The 647050-4 is supplied in standard packaging (not specified). The 3-647050-4 is supplied in Bulk packaging. The 0022231045 is supplied in Tube packaging. Packaging format may affect handling, storage, and integration into assembly processes. Verify packaging compatibility with your procurement and assembly requirements.

Q: Do all substitute parts meet the same compliance standards?

A: The 647050-4 and 3-647050-4 are both ROHS3 Compliant. The 0022231045 is also ROHS3 Compliant. All three parts carry UL94 V-0 material flammability rating and Moisture Sensitivity Level 1 (Unlimited). All parts are classified as EAR99 for export control purposes. The 647050-4 and 3-647050-4 carry identical HTSUS classification (8536.69.4040), as does the 0022231045.

Q: What is the significance of the contact finish differences?

A: The 647050-4 features Tin-Lead mating contact finish (80.0µin thickness). The 3-647050-4 features Tin mating contact finish (80.0µin thickness). The 0022231045 features Gold mating contact finish (20.0µin thickness). Tin and Tin-Lead finishes provide standard solderability and electrical performance. Gold plating offers enhanced corrosion resistance and contact reliability in high-reliability or harsh environment applications. All finishes are compatible with standard solder termination processes.

Q: Are there temperature or voltage rating considerations for the Molex substitute?

A: The 647050-4 and 3-647050-4 specify operating temperature range of -55°C to 105°C and voltage rating of 250VAC. The 0022231045 does not provide operating temperature or voltage rating specifications in available documentation. When operating temperature or voltage specifications are critical to your application, design verification with the Molex part is required before implementation.

Q: Can these connectors be used interchangeably in existing designs?

A: The 3-647050-4 is a direct equivalent and can be used interchangeably with the 647050-4 in existing designs without modification. The 0022231045 maintains functional compatibility due to matching pitch, position count, and mounting characteristics. However, minor dimensional variations in contact lengths and insulation height may affect fit in space-constrained applications. Physical verification is recommended when dimensional tolerances are critical.
