TE Connectivity 641149-5 MTA-156 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 641149-5 is a 5-position rectangular receptacle connector from the MTA-156 series, designed for IDC (Insulation Displacement Contact) termination with 20 AWG discrete or ribbon cable. This connector features gold-plated female socket contacts, a locking ramp fastening mechanism, and closed-end construction in yellow housing. The part is currently active in the product lifecycle and maintains full RoHS compliance with MSL 1 rating. Substitute parts are identified to provide alternative sourcing options when the primary part number becomes unavailable or when inventory requirements necessitate alternative stock sources.

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 641149-5 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 3-641149-5 qualifies as a direct equivalent based on the following matching criteria:

Critical Matching Parameters:

• Connector type, contact type, and position count (5-position receptacle with female sockets)
• Pitch specification (0.156" / 3.96mm)
• Single-row configuration
• IDC cable termination method with 20 AWG wire gauge compatibility
• Gold contact finish with identical thickness specification (15.0µin / 0.38µm)
• Identical series designation (MTA-156)
• Matching fastening mechanism (locking ramp)
• Equivalent environmental and compliance ratings (RoHS compliant, MSL 1)

The substitute part maintains functional and mechanical interchangeability with the primary part number across all specified parameters.

Engineering Selection Recommendations

Primary Part Selection (641149-5): The TE Connectivity 641149-5 is the recommended selection for new designs and ongoing production. This part maintains active product status with confirmed inventory availability (707 pieces in stock). Full RoHS compliance and MSL 1 rating ensure compatibility with standard manufacturing and storage environments without moisture sensitivity constraints.

Substitute Part Selection (3-641149-5): The part number 3-641149-5 provides functional equivalence for applications requiring component substitution due to supply constraints or inventory management. This substitute maintains identical electrical and mechanical specifications, including contact finish thickness, pitch, and termination method. However, this part is discontinued at DiGi Electronics, which may limit future availability. Selection of this substitute should account for current inventory status (993 pieces available) and long-term supply chain considerations.

Compliance and Certification: Both parts maintain RoHS compliance and carry MSL 1 rating, confirming suitability for standard industrial and commercial applications without special handling requirements. ECCN classification (EAR99) and HTSUS code (8536.69.8000) are identical across both part numbers.

Frequently Asked Questions (FAQ)

Q: Are the 641149-5 and 3-641149-5 connectors mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including pitch (0.156"), position count (5), mounting type (free hanging in-line), and fastening mechanism (locking ramp). They are direct mechanical equivalents.

Q: Can these connectors be used interchangeably in existing cable assemblies?

A: Yes. The connectors are electrically and mechanically equivalent. Both accept 20 AWG discrete or ribbon cable via IDC termination and feature identical gold contact finish specifications (15.0µin thickness). Existing cable assemblies designed for one part number function identically with the substitute.

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

A: The primary difference is product lifecycle status. The 641149-5 maintains active status with ongoing manufacturer support, while 3-641149-5 is discontinued at DiGi Electronics. All electrical, mechanical, and compliance specifications are identical.

Q: Are there any environmental or storage differences between these parts?

A: No. Both parts carry MSL 1 rating, indicating unlimited moisture sensitivity level. Storage and handling requirements are identical, with no special environmental controls required.

Q: Which part should be selected for new production designs?

A: The 641149-5 is the appropriate selection for new designs due to its active product status and confirmed long-term availability. The 3-641149-5 substitute is suitable only when the primary part becomes unavailable or for existing inventory management purposes.

Q: Are the contact finish specifications identical?

A: Yes. Both connectors feature gold contact finish with identical thickness specification of 15.0µin (0.38µm), ensuring equivalent electrical performance and contact reliability.

Q: Can these connectors be mixed in the same application?

A: Yes. The connectors are fully equivalent and can be used together in the same application without compatibility issues. However, for production consistency and supply chain management, using a single part number is recommended.
