Critical Matching Parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 11
• Number of Rows: 1
• Connector Type: Header with Male Pin contacts
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Contact Shape: Square
• Shrouding: Unshrouded

Acceptable Variation Parameters:

• Contact Length - Mating: Variations permitted within mechanical envelope constraints
• Contact Length - Post: Variations permitted within PCB assembly requirements
• Insulation Height: Variations permitted within connector body design
• Contact Finish: Variations in plating material and thickness permitted based on application requirements
• Insulation Material: Variations in thermoplastic composition permitted
• Operating Temperature Range: Substitute must support minimum -40°C ~ 105°C
• Material Flammability Rating: UL94 V-0 required

All identified substitute parts maintain the critical matching parameters while offering variations in contact finish, insulation material composition, and operating temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 929500-01-11-RK (3M)

The 3M 929500-01-11-RK is the preferred substitute for the obsolete TE Connectivity 1-644457-1. This part maintains all critical matching parameters including 11-position, 0.100" pitch, through-hole right-angle configuration with square male pin contacts. The 929500-01-11-RK carries active product status, ensuring continued availability and supply chain stability. The part meets UL94 V-0 flammability requirements and operates across the -40°C ~ 105°C temperature range, which encompasses the original part's lower temperature specification of -55°C. The tin contact finish with 200.0µin (5.08µm) thickness provides robust solderability and corrosion resistance suitable for general-purpose applications.

Secondary Recommendation: 929550-01-11-EU (3M)

The 3M 929550-01-11-EU serves as an alternative substitute with identical mechanical and electrical compatibility. This variant features gold contact finish on both mating and post surfaces with 10.0µin (0.25µm) thickness, offering enhanced corrosion resistance for applications requiring extended shelf life or exposure to corrosive environments. The part maintains active product status and full compliance with REACH regulations. The PCT insulation material provides superior thermal and chemical resistance compared to standard polyester formulations.

Tertiary Recommendation: 929550-01-11-I (3M)

The 3M 929550-01-11-I provides functional equivalence with gold contact finish and PBT glass-filled insulation material. This part is suitable for applications where enhanced mechanical strength and dimensional stability are required. Active product status ensures availability, though RoHS non-compliance status should be evaluated against specific application requirements.

Alternative Consideration: 0022122111 (Molex)

The Molex 0022122111 offers full mechanical and electrical compatibility with active product status and ROHS3 compliance. The gold contact finish and polyamide insulation material provide alternative material selections. The increased contact length (0.369" mating vs. 0.260" original) requires verification of mechanical clearance in existing PCB designs before implementation.

Not Recommended: 929500-01-11 (3M)

The 3M 929500-01-11 carries Last Time Buy product status, indicating discontinued manufacturing and limited future availability. While functionally equivalent, this part should not be selected for new designs or long-term production requirements.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine if a part can substitute for the 1-644457-1?

A: The following parameters must match exactly: 0.100" (2.54mm) pitch spacing, 11 positions in a single row, header connector type with male pin contacts, through-hole right-angle mounting, solder termination, unshrouded configuration, and square contact shape. Variations in contact finish, insulation material composition, and contact length are acceptable provided they do not exceed mechanical envelope constraints.

Q: Can I use the Molex 0022122111 as a direct replacement?

A: The Molex 0022122111 maintains all critical electrical and mechanical parameters for functional substitution. However, the increased contact length (0.369" vs. 0.260") requires verification that existing PCB designs accommodate the longer mating contact without interference. Physical testing or design review is necessary before implementation in existing assemblies.

Q: What is the difference between the 3M 929500-01-11-RK and 929550-01-11-EU?

A: Both parts are mechanically and electrically equivalent with identical pitch, position count, and mounting configuration. The primary difference is contact finish: the 929500-01-11-RK features tin plating (200.0µin thickness) while the 929550-01-11-EU features gold plating (10.0µin thickness). Gold-plated contacts provide superior corrosion resistance and are preferred for applications with extended storage periods or exposure to corrosive environments. Tin-plated contacts offer cost efficiency for standard applications.

Q: Why is the 929500-01-11 not recommended despite functional equivalence?

A: The 929500-01-11 carries Last Time Buy product status, indicating that the manufacturer has discontinued production and will not accept new orders beyond a specified cutoff date. For new designs or ongoing production requirements, active status parts such as 929500-01-11-RK or 929550-01-11-EU ensure long-term supply chain continuity.

Q: Are there compliance differences between substitute options?

A: Yes. The Molex 0022122111 is ROHS3 compliant, while the 3M 929550-01-11-I and original 1-644457-1 are RoHS non-compliant. The 3M 929500-01-11-RK and 929550-01-11-EU do not specify RoHS status. All substitute parts are REACH unaffected or compliant. Application requirements and regulatory mandates should determine compliance selection.

Q: What is the operating temperature difference between the original part and substitutes?

A: The original 1-644457-1 operates from -55°C to 105°C, while all substitute parts operate from -40°C to 105°C. The substitute parts have a higher minimum temperature specification by 15°C. For applications requiring operation below -40°C, the original part specification must be maintained or alternative components evaluated.

Q: Can I mix different substitute parts in the same assembly?

A: All identified substitute parts maintain identical pitch, position count, and mounting configuration, allowing mechanical interchangeability within a single assembly. However, mixing different contact finishes (tin vs. gold) in the same connector interface is not recommended due to potential galvanic corrosion at dissimilar metal contact points. Standardize on a single substitute part across all connector positions within an assembly.

Q: What packaging options are available for these substitutes?

A: All substitute parts are supplied in bulk packaging. The original 1-644457-1 packaging specification was not provided. Bulk packaging is standard for through-hole connector headers and does not affect functional performance or compatibility.
