TE Connectivity AMP Connectors 644233-6 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 644233-6 is a 6-position rectangular connector receptacle housing with 0.156" (3.96mm) pitch, designed for free-hanging in-line applications. This connector features crimp contact termination and locking ramp fastening, constructed from polyamide (PA) nylon insulation material. The part operates across a temperature range of -55°C to 105°C and is RoHS compliant with MSL 1 (unlimited moisture sensitivity level). The 644233-6 maintains active product status with 783 pieces currently in stock. Substitute parts are identified to provide alternative sourcing options when the primary part number becomes unavailable or when inventory requirements necessitate alternative stock sources.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 644233-6 are qualified based on strict parametric equivalence within the SL-156 series of rectangular connectors. All substitute parts maintain identical specifications across the following critical parameters: 6-position receptacle housing configuration, 0.156" (3.96mm) pitch, female socket contact type, single-row arrangement, free-hanging in-line mounting, crimp termination, locking ramp fastening, polyamide nylon insulation material, and -55°C to 105°C operating temperature range. All substitute parts are RoHS compliant with MSL 1 rating. Substitution is valid only when these parameters remain constant across the application requirement. Parts are grouped by product status and compliance certifications to facilitate selection based on availability and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status): The 647401-6 is the recommended substitute for the 644233-6 due to its active product status and highest current inventory level of 2133 pieces. Both parts maintain identical electrical and mechanical parameters within the SL-156 series and are RoHS compliant.

Secondary Selection (Active Status): The 2132189-6 serves as an alternative active substitute with 945 pieces in inventory. This part maintains full parametric equivalence and carries REACH Unaffected compliance status, providing an additional sourcing option.

Tertiary Consideration (Obsolete Status): The 770707-6 is classified as obsolete and should not be selected for new designs or long-term applications. While parametrically equivalent and currently in stock with 731 pieces, its obsolete status indicates discontinued manufacturer support and potential future unavailability.

All three substitute parts are RoHS compliant with MSL 1 rating, matching the primary part's regulatory compliance profile. Selection between active parts should be based on inventory availability and supply chain requirements rather than technical parameters, as all active alternatives are functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can 647401-6 be used as a direct replacement for 644233-6?

A: Yes. The 647401-6 is a parametric equivalent within the SL-156 series. Both parts share identical specifications for connector type, position count, pitch, mounting configuration, termination method, fastening type, insulation material, and operating temperature range. Both are RoHS compliant with MSL 1 rating.

Q: What is the difference between the substitute parts?

A: All substitute parts (2132189-6, 647401-6, and 770707-6) are parametrically identical. The primary differences are product status and inventory levels. The 647401-6 and 2132189-6 maintain active status, while 770707-6 is obsolete. Current inventory levels are 2133 pieces (647401-6), 945 pieces (2132189-6), and 731 pieces (770707-6).

Q: Why is 770707-6 listed if it is obsolete?

A: The 770707-6 is included in the substitute list due to its parametric equivalence and current stock availability. However, its obsolete status indicates that the manufacturer has discontinued production and support. This part should not be selected for new designs or applications requiring long-term availability.

Q: Are there any packaging differences between substitute parts?

A: The 644233-6 and 647401-6 are packaged in bulk. The 2132189-6 is also packaged in bulk. The 770707-6 packaging information is not specified in available data. Packaging differences do not affect functional compatibility.

Q: Do all substitute parts require the same contact specifications?

A: Yes. All parts are receptacle housings with female socket contacts designed for crimp termination. Contacts are not included with any of these housing parts and must be sourced separately. Contact specifications must match the 0.156" (3.96mm) pitch requirement of the SL-156 series.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts are RoHS compliant and carry MSL 1 (unlimited) moisture sensitivity level rating. The 2132189-6 carries REACH Unaffected status. The 644233-6 and 647401-6 have vendor-undefined REACH status. All parts are classified under ECCN EAR99.

Q: Can these parts be used in applications with operating temperatures outside -55°C to 105°C?

A: No. All substitute parts, including the primary 644233-6, are rated for operation only within the -55°C to 105°C temperature range. Applications requiring different temperature specifications require alternative part selection outside this series.
