TE Connectivity AMP 1-644457-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP 1-644457-3 is a rectangular connector header, right-angle configuration, with 13 positions at 0.100" (2.54mm) pitch. This through-hole, solder-terminated component is designed for board-to-cable/wire applications in general-purpose electronic assemblies. The part operates across a temperature range of -55°C to 105°C with a 250VAC voltage rating and UL94 V-0 flammability compliance.

The 1-644457-3 carries an obsolete product status, necessitating identification of active equivalent alternatives that maintain functional compatibility while meeting current supply chain requirements. Substitute parts must preserve critical electrical and mechanical parameters including pitch, position count, mounting type, and termination method.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1-644457-3 is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 13
• Number of Rows: 1
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Contact Shape: Square
• Contact Material: Copper Alloy

Allowable Variations:

• Connector subtype (Header vs. Header Breakaway)
• Insulation material composition (Thermoplastic vs. PBT, Polyester, Glass Filled vs. PCT)
• Contact finish composition (Tin-Lead vs. Tin vs. Gold)
• Contact finish thickness
• Insulation color
• Operating temperature minimum threshold (provided maximum does not fall below 105°C)
• Product status (Obsolete to Active transition)
• RoHS and REACH compliance status

The four substitute parts listed below satisfy all mandatory matching parameters and are therefore electrically and mechanically compatible with the 1-644457-3 in board-to-board or board-to-cable applications requiring 13-position, 2.54mm-pitch header connectors.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 929500-01-13-RK (3M)

The 929500-01-13-RK is the optimal substitute for the obsolete 1-644457-3. This part achieves RoHS compliance and REACH unaffected status, addressing regulatory requirements that the original part does not satisfy. The contact finish composition (Tin with 200.0µin thickness) provides enhanced durability compared to the thinner Tin-Lead finish of the original specification. The PCT insulation material offers superior thermal and chemical resistance. Active product status ensures long-term supply chain availability.

Secondary Recommendation: 929550-01-13-EU (3M)

The 929550-01-13-EU provides gold-plated contact surfaces (10.0µin thickness), delivering superior corrosion resistance and contact reliability in applications requiring enhanced environmental protection. This part achieves RoHS compliance and REACH unaffected status. PCT insulation material matches the thermal performance of the primary recommendation. Active product status supports sustained availability.

Alternative Option: 929500-01-13 (3M)

The 929500-01-13 maintains functional compatibility with identical electrical and mechanical parameters to the primary recommendation. This part carries REACH affected status and RoHS non-compliant designation. Selection of this part is appropriate only when regulatory compliance requirements do not apply to the end application.

Alternative Option: 929550-01-13-I (3M)

The 929550-01-13-I provides gold-plated contacts with PBT insulation material. This part carries REACH unaffected status but maintains RoHS non-compliant designation. Selection is appropriate for applications requiring enhanced contact reliability without RoHS compliance mandates.

Operating Temperature Consideration:

All substitute parts operate to a minimum of -40°C, compared to the original part's -55°C minimum. Applications requiring operation below -40°C require engineering evaluation to confirm thermal performance adequacy.

Frequently Asked Questions (FAQ)

Q: Can the 3M 929 series parts directly replace the TE Connectivity MTA-100 1-644457-3?

A: Yes. All four substitute parts maintain identical pitch (0.100"/2.54mm), position count (13), row configuration (1), mounting type (through-hole right-angle), termination method (solder), and contact geometry (square male pins). Electrical and mechanical compatibility is established.

Q: What is the significance of the contact length differences between the original part and substitutes?

A: The original 1-644457-3 specifies mating contact length of 0.260" (6.60mm) and post length of 0.110" (2.79mm). All substitute parts specify 0.295" (7.49mm) mating length and 0.130" (3.30mm) post length. These dimensional variations do not affect functional compatibility in standard board-to-board or board-to-cable applications. Verification is required only for applications with space constraints or custom mating interface specifications.

Q: Which substitute part offers the best environmental protection?

A: The 929550-01-13-EU and 929550-01-13-I both feature gold-plated contact surfaces (10.0µin thickness), providing superior corrosion resistance compared to tin or tin-lead finishes. Gold plating is recommended for applications exposed to moisture, salt spray, or corrosive atmospheres.

Q: Are there RoHS compliance differences among the substitute parts?

A: Yes. The 929500-01-13-RK and 929550-01-13-EU are RoHS compliant. The 929500-01-13 and 929550-01-13-I are RoHS non-compliant. Selection depends on end-product regulatory requirements. The original 1-644457-3 is RoHS non-compliant.

Q: What is the difference between REACH affected and REACH unaffected status?

A: REACH affected status indicates the part may contain substances of very high concern (SVHC) requiring compliance documentation. REACH unaffected status indicates the part does not contain listed SVHC substances. The 929500-01-13 carries REACH affected status; all other substitutes carry REACH unaffected status. Selection depends on supply chain compliance requirements.

Q: Does the insulation material change affect thermal performance?

A: The original part uses thermoplastic insulation. Substitute parts use either PBT (polybutylene terephthalate) with polyester and glass filler or PCT (polycyclohexylenedimethylene terephthalate). Both materials provide superior thermal stability and chemical resistance compared to standard thermoplastic. All parts maintain UL94 V-0 flammability rating. Thermal performance is equivalent or superior across all substitutes.

Q: What is the minimum operating temperature difference between the original and substitute parts?

A: The original 1-644457-3 operates to -55°C minimum. All substitute parts operate to -40°C minimum. This 15°C difference is significant only for applications requiring operation in extreme cold environments. Standard industrial and commercial applications operating above -40°C are unaffected.

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

A: All substitute parts are manufactured by 3M. The original part is manufactured by TE Connectivity. Within a single assembly, mixing parts from different manufacturers is permissible provided all parts meet the same electrical, mechanical, and compliance specifications. Verification of mating interface compatibility is required.

Q: What is the current rating difference between the original and substitute parts?

A: The original 1-644457-3 specifies current rating as "varies by wire gauge," indicating current capacity is determined by the connected wire gauge rather than the connector itself. All substitute parts specify 2.5A current rating. For applications requiring current capacity verification, the 2.5A specification of substitute parts provides a defined maximum rating.

Q: Are the substitute parts available in the same packaging as the original?

A: The original 1-644457-3 packaging is not specified in the provided data. All substitute parts are supplied in bulk packaging. Packaging configuration should be verified with the supplier to confirm compatibility with assembly processes and inventory management requirements.
