TE Connectivity 641148-6 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 641148-6 is a 6-position rectangular receptacle connector from the MTA-156 series, designed for IDC (Insulation Displacement Contact) termination with 18 AWG wire. This connector features gold-plated female socket contacts, a closed-end design, and free-hanging in-line mounting with locking ramp fastening. The part is currently active in production with 1082 pieces available in new original inventory.

Substitute parts are identified when equivalent electrical and mechanical specifications are maintained across connector geometry, contact configuration, termination method, and wire gauge compatibility. Alternative part numbers may differ in packaging format or compliance certifications while preserving functional interchangeability.

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 641148-6 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

Contact type (Female Socket)
Number of positions (6)
Wire gauge (18 AWG)
Contact finish (Gold)

Mechanical Compatibility Parameters:

Pitch spacing (0.156" / 3.96mm)
Number of rows (1)
Connector type (Receptacle)
Mounting configuration (Free Hanging In-Line)
Fastening mechanism (Locking Ramp)
Cable termination method (IDC)

Physical Characteristics:

Closed-end design
Series designation (MTA-156)

The substitute part 3-641148-6 maintains identical specifications across all electrical and mechanical parameters. The primary distinction is packaging format (Bulk versus standard packaging) and RoHS compliance status.

Engineering Selection Recommendations

Both the 641148-6 and 3-641148-6 are functionally equivalent rectangular receptacle connectors from TE Connectivity's MTA-156 series. Selection between these parts is determined by regulatory and packaging requirements rather than electrical or mechanical performance.

641148-6 Selection Criteria:

Applications where RoHS non-compliant components are acceptable
Standard packaging requirements
Current inventory availability (1082 pieces)

3-641148-6 Selection Criteria:

Applications requiring RoHS compliance certification
Bulk packaging format for high-volume assembly operations
Regulatory environments mandating RoHS-compliant component sourcing
Current inventory availability (1038 pieces)

Both parts maintain identical electrical performance, mechanical compatibility, and physical dimensions. The choice between these substitutes depends exclusively on compliance requirements and packaging specifications for the end application.

Frequently Asked Questions (FAQ)

Q: Are the 641148-6 and 3-641148-6 electrically interchangeable?

A: Yes. Both connectors feature identical contact configurations, wire gauge compatibility (18 AWG), pitch spacing (0.156"), and gold-plated contact finishes. They perform identically in electrical applications.

Q: What is the primary difference between these two part numbers?

A: The primary differences are RoHS compliance status (641148-6 is non-compliant; 3-641148-6 is compliant) and packaging format (641148-6 uses standard packaging; 3-641148-6 uses bulk packaging).

Q: Can I use the 3-641148-6 as a direct replacement for the 641148-6 in existing designs?

A: Yes, provided your application permits RoHS-compliant components. The 3-641148-6 maintains all electrical and mechanical specifications of the 641148-6.

Q: Are there any mechanical compatibility issues between these parts?

A: No. Both connectors share identical mounting type (free hanging in-line), fastening mechanism (locking ramp), and physical dimensions. They are mechanically interchangeable.

Q: What wire gauges are compatible with these connectors?

A: Both connectors are specified for 18 AWG wire. They support discrete or ribbon cable termination via IDC (Insulation Displacement Contact) method.

Q: Do these connectors require any special handling or storage conditions?

A: Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling.

Q: What is the pitch spacing of these connectors?

A: Both connectors feature 0.156" (3.96mm) pitch spacing, which is the standard spacing for the MTA-156 series.

Q: Are these connectors suitable for ribbon cable applications?

A: Yes. Both connectors support discrete or ribbon cable termination through their IDC termination method.
