Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 4-640433-0 are identified based on strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 10
• Pitch: 0.156" (3.96mm)
• Cable Termination: IDC
• Wire Gauge: 22 AWG
• Contact Finish: Tin
• Contact Finish Thickness: 80.0µin (2.03µm)

Mechanical Compatibility Parameters:

• Series: MTA-156
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line)
• Features: Closed End
• Color: Red

Compliance Parameters:

• RoHS Status: RoHS Compliant or ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part 4-640428-0 maintains full electrical and mechanical equivalence with the main part across all specified parameters. The primary distinction is the addition of a Locking Ramp fastening feature in the substitute part, which provides enhanced mechanical retention without altering the core electrical or dimensional specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (4-640433-0): The 4-640433-0 is suitable for applications requiring a 10-position IDC receptacle connector with standard mechanical retention. This part maintains Active product status and full RoHS compliance. Selection is appropriate when fastening requirements do not necessitate additional mechanical locking features.

Substitute Part Selection (4-640428-0): The 4-640428-0 is electrically and mechanically equivalent to the main part with the addition of a Locking Ramp fastening mechanism. This substitute is suitable for applications requiring enhanced mechanical retention and mating security. The substitute part meets ROHS3 compliance, which represents an enhanced environmental standard relative to RoHS compliance. Both parts maintain identical electrical performance, dimensional specifications, and contact characteristics. The substitute part demonstrates higher current inventory availability (1493 units versus 745 units).

Compliance Considerations: Both parts are classified as Active products with unlimited moisture sensitivity rating (MSL 1). The substitute part's ROHS3 compliance status indicates adherence to more recent regulatory requirements. Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications.

Frequently Asked Questions (FAQ)

Q: Can the 4-640428-0 be used as a direct replacement for the 4-640433-0?

A: Yes. The 4-640428-0 is electrically and mechanically equivalent to the 4-640433-0 across all critical parameters including connector type, contact configuration, pitch, termination method, wire gauge, and contact finish. The primary difference is the addition of a Locking Ramp fastening feature on the substitute part, which provides enhanced mechanical retention without affecting electrical performance or dimensional compatibility.

Q: What is the difference between the Locking Ramp fastening type and no fastening type?

A: The Locking Ramp fastening mechanism on the 4-640428-0 provides additional mechanical retention and mating security compared to the standard design of the 4-640433-0. Both connectors maintain identical electrical and dimensional specifications. The Locking Ramp feature enhances mechanical stability in applications subject to vibration or frequent mating cycles.

Q: Are both parts compatible with the same cable types?

A: Yes. Both the 4-640433-0 and 4-640428-0 support identical cable termination specifications: IDC (Insulation Displacement Contact) termination with 22 AWG discrete or ribbon cable.

Q: What is the significance of ROHS3 compliance on the substitute part?

A: ROHS3 compliance indicates adherence to the most recent Restriction of Hazardous Substances directive requirements. The main part carries RoHS compliance, while the substitute carries ROHS3 compliance. Both designations confirm the absence of restricted hazardous substances. ROHS3 represents an updated regulatory standard.

Q: Are there inventory considerations when selecting between these parts?

A: Yes. The 4-640428-0 substitute part has higher current inventory availability (1493 units) compared to the 4-640433-0 main part (745 units). This may be a relevant factor for supply chain planning and lead time considerations.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both the 4-640433-0 and 4-640428-0 carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or use.

Q: Are the contact finish specifications identical between both parts?

A: Yes. Both parts feature tin contact finish with identical thickness specifications of 80.0µin (2.03µm). This ensures equivalent electrical contact characteristics and corrosion resistance.
