Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-640440-4 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Series: MTA-100
• Connector Type: Receptacle
• Number of Positions: 14
• Pitch: 0.100" (2.54mm)
• Contact Type: Female Socket
• Cable Termination: IDC
• Wire Gauge: 22 AWG
• Mounting Type: Free Hanging (In-Line), Right Angle
• Fastening Type: Locking Ramp
• Features: Closed End

Allowable Variations:

• Contact Finish: Tin-Lead to Tin (both provide equivalent electrical and mechanical performance within the MTA-100 series specification)
• Product Status: Obsolete to Active (substitution driven by availability and compliance requirements)
• RoHS Compliance: Non-compliant to ROHS3 Compliant (represents product evolution within the same connector family)

The substitute part 4-640440-4 maintains full mechanical and electrical compatibility with the original 1-640440-4 while offering improved availability and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 4-640440-4

The 4-640440-4 is the direct active equivalent of the obsolete 1-640440-4. Selection of this substitute is based on the following engineering criteria:

Product Status Alignment: The 4-640440-4 maintains active product status within the TE Connectivity MTA-100 series, ensuring long-term availability and continued manufacturer support compared to the obsolete 1-640440-4.

Regulatory Compliance: The 4-640440-4 achieves ROHS3 compliance, meeting current environmental and regulatory requirements. The original 1-640440-4 is RoHS non-compliant, which may restrict its use in applications subject to RoHS directives.

Mechanical and Electrical Equivalence: All critical connector parameters remain identical between the two parts, including pitch, position count, contact type, termination method, and mounting configuration. The connector maintains full interchangeability in applications designed for the MTA-100 series.

Contact Finish Variation: The transition from tin-lead to tin contact finish represents a material specification change within the same connector family. Both finishes provide equivalent electrical conductivity and mechanical performance at the specified contact finish thickness of 80.0µin (2.03µm).

Inventory and Availability: The 4-640440-4 is available in significantly higher quantities (1559 pcs) compared to the original part (927 pcs), supporting both immediate requirements and long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the 4-640440-4 be used as a direct replacement for the 1-640440-4 in existing applications?

A: Yes. The 4-640440-4 is mechanically and electrically equivalent to the 1-640440-4 across all critical connector parameters. Both parts are MTA-100 series 14-position receptacles with identical pitch, contact configuration, termination method, and mounting type. The connector will function identically in applications designed for the original part.

Q: What is the difference between the tin-lead finish on the 1-640440-4 and the tin finish on the 4-640440-4?

A: Both finishes are applied at the same thickness (80.0µin / 2.03µm) and provide equivalent electrical conductivity and mechanical performance within the MTA-100 series specification. The tin finish on the 4-640440-4 represents a material specification update that supports improved regulatory compliance.

Q: Why is the 1-640440-4 listed as obsolete?

A: The 1-640440-4 has been discontinued by TE Connectivity. The 4-640440-4 is the active replacement within the MTA-100 series and is recommended for all new designs and ongoing applications.

Q: Does the RoHS3 compliance of the 4-640440-4 affect its electrical performance compared to the non-compliant 1-640440-4?

A: No. RoHS3 compliance is a regulatory and material composition requirement, not an electrical performance specification. Both parts deliver identical electrical characteristics and are suitable for the same applications.

Q: Are there any packaging differences between the 1-640440-4 and 4-640440-4?

A: The 4-640440-4 is supplied in bulk packaging, while the original part packaging specification is not provided. Both parts are identical in connector form, fit, and function. Packaging differences do not affect connector performance or interchangeability.

Q: Can the 4-640440-4 be used with both discrete and ribbon cable?

A: Yes. The 4-640440-4 supports both discrete and ribbon cable termination via IDC (Insulation Displacement Contact) technology, identical to the original 1-640440-4. The 22 AWG wire gauge specification applies to both cable types.

Q: What is the moisture sensitivity level for the 4-640440-4?

A: The moisture sensitivity level is 1 (Unlimited), indicating no moisture sensitivity restrictions. The connector can be stored and handled under standard environmental conditions without special moisture control measures.
