TE Connectivity 4-641238-1 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 4-641238-1 is an 11-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 24 AWG discrete or ribbon cable. This connector features gold-plated contacts and is classified as Active product status with full RoHS3 compliance. Substitute parts are identified when inventory constraints, specific contact finish requirements, or compliance certifications necessitate alternative component selection while maintaining functional equivalence within the MTA-100 series.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the MTA-100 series is determined by strict equivalence across the following parameters: connector type (receptacle), number of positions (11), pitch (0.100"), number of rows (1), contact type (female socket), cable termination method (IDC), wire gauge (24 AWG), wire type compatibility (discrete or ribbon cable), mounting type (free hanging in-line and right angle), and fastening type (locking ramp). The primary variable distinguishing substitute parts is contact finish material and associated finish thickness, which does not affect mechanical or electrical compatibility within the specified parameter set. All substitute parts maintain identical series designation, position count, pitch, and termination methodology.

Parameter Comparison

Engineering Selection Recommendations

Both 4-641238-1 and 4-640441-1 are Active product status components within the MTA-100 rectangular connector series and are suitable for direct substitution based on mechanical and electrical parameter equivalence. The 4-641238-1 features gold contact finish with 30.0µin thickness and carries RoHS3 Compliant certification. The 4-640441-1 features tin contact finish with 80.0µin thickness and carries RoHS Compliant certification. Both components maintain MSL 1 (Unlimited) moisture sensitivity rating and identical ECCN and HTSUS classifications. Selection between these parts is determined by specific application requirements regarding contact finish material and associated corrosion resistance characteristics, as well as compliance certification requirements. Current inventory availability shows 1160 units of 4-641238-1 and 7199 units of 4-640441-1.

Frequently Asked Questions (FAQ)

Q: Can 4-640441-1 be used as a direct replacement for 4-641238-1?

A: Yes. Both connectors are mechanically and electrically equivalent within the MTA-100 series, sharing identical position count (11), pitch (0.100"), contact type (female socket), cable termination method (IDC), wire gauge (24 AWG), mounting configuration, and fastening mechanism. The primary difference is contact finish material: gold versus tin.

Q: What is the functional difference between gold and tin contact finishes?

A: Contact finish material affects corrosion resistance and contact resistance characteristics. Gold finish (4-641238-1) provides superior corrosion resistance with 30.0µin thickness. Tin finish (4-640441-1) offers different contact resistance properties with 80.0µin thickness. Selection depends on application environment and electrical performance requirements.

Q: Are both parts RoHS compliant?

A: Yes. The 4-641238-1 is RoHS3 Compliant. The 4-640441-1 is RoHS Compliant. Both meet regulatory requirements for their respective certifications.

Q: Can these connectors accommodate both discrete and ribbon cable?

A: Yes. Both 4-641238-1 and 4-640441-1 are specified for discrete or ribbon cable termination using IDC methodology at 24 AWG wire gauge.

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

A: Both connectors carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Are there inventory considerations for part selection?

A: Current inventory shows 1160 units of 4-641238-1 and 7199 units of 4-640441-1 in stock. Availability may influence selection timing for procurement planning.
