Key Parameters

Substitute Part Grouping Explanation

Substitution between the main part (1-640428-7) and the identified equivalent (4-640428-7) is based on the following criteria:

Electrical Interface Compatibility:

• Identical number of positions (17)
• Identical pitch specification (0.156" / 3.96mm)
• Identical contact type (Female Socket)
• Identical wire gauge (22 AWG)
• Identical contact finish thickness (80.0µin / 2.03µm)

Mechanical Interface Compatibility:

• Identical connector type (Rectangular Receptacle)
• Identical mounting type (Free Hanging, In-Line)
• Identical fastening type (Locking Ramp)
• Identical cable termination method (IDC)
• Identical number of rows (1)
• Identical features (Closed End)
• Identical color (Red)

Series Compatibility:

• Both parts belong to the MTA-156 series

The primary difference between these parts is the contact finish material (tin-lead versus tin) and RoHS compliance status. Both parts maintain identical mechanical and electrical interface specifications, allowing direct substitution in applications where the specific contact finish material and regulatory compliance requirements are compatible.

Parameter Comparison

Engineering Selection Recommendations

For RoHS3 Compliant Applications: Select part 4-640428-7. This substitute maintains all electrical and mechanical interface specifications while providing ROHS3 compliance certification. The tin contact finish is suitable for applications requiring lead-free materials.

For Legacy or Non-Regulated Applications: Either part 1-640428-7 or 4-640428-7 is acceptable. The 1-640428-7 with tin-lead contact finish may be selected where RoHS compliance is not a requirement and tin-lead materials are specified.

For Bulk Procurement: Part 4-640428-7 is available in bulk packaging with higher inventory availability (1439 units versus 1090 units), supporting larger production runs.

Contact Finish Considerations: The contact finish difference (tin-lead versus tin) does not affect mechanical or electrical interface compatibility. Selection between these finishes depends on application-specific requirements, environmental conditions, and regulatory mandates.

Frequently Asked Questions (FAQ)

Q: Can 4-640428-7 be used as a direct replacement for 1-640428-7?

A: Yes. Both parts share identical electrical and mechanical interface specifications, including connector type, position count, pitch, contact type, wire gauge, mounting configuration, and fastening method. The primary differences are contact finish material and RoHS compliance status.

Q: What is the difference between tin-lead and tin contact finishes?

A: The 1-640428-7 features tin-lead contact finish, while the 4-640428-7 features tin contact finish. Both maintain the same contact finish thickness (80.0µin / 2.03µm). The selection between these finishes depends on application requirements and regulatory compliance mandates.

Q: Is the 4-640428-7 RoHS compliant?

A: Yes. The 4-640428-7 is ROHS3 compliant. The 1-640428-7 is RoHS non-compliant.

Q: Are the pitch and position specifications identical between these parts?

A: Yes. Both parts feature 17 positions with 0.156" (3.96mm) pitch, ensuring mechanical and electrical compatibility in MTA-156 series applications.

Q: What is the wire gauge specification for both parts?

A: Both parts are rated for 22 AWG discrete or ribbon cable termination using IDC (Insulation Displacement Contact) technology.

Q: Do both parts support the same mounting configuration?

A: Yes. Both parts are free-hanging, in-line mounted receptacles with locking ramp fastening and closed-end design.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.

Q: Are there packaging differences between these parts?

A: The 1-640428-7 packaging is not specified in the product data. The 4-640428-7 is supplied in bulk packaging. Inventory availability differs: 1090 units for 1-640428-7 and 1439 units for 4-640428-7.
