TE Connectivity AMP Connectors 4-644992-0 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 4-644992-0 is an active rectangular connector header designed for through-hole mounting applications. This shrouded, single-wall header connector accommodates 10 positions at 0.156" (3.96mm) pitch and is configured for board-to-cable or board-to-board interconnection. The connector features male pin contacts with solder termination and friction lock fastening. Substitute parts are identified to address inventory availability, application-specific requirements, or design flexibility while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector headers is determined by alignment of core mating parameters that ensure mechanical and electrical interchangeability. The following parameters establish substitution validity:

Primary Substitution Criteria:

• Connector Type: Header
• Contact Type: Male Pin
• Pitch - Mating: 0.156" (3.96mm)
• Number of Positions: 10
• Number of Rows: 1
• Shrouding: Shrouded - 1 Wall
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Friction Lock
• Contact Shape: Square
• Material Flammability Rating: UL94 V-0

The identified substitute parts (Molex 0026604100 and Molex 0417910840) satisfy all primary substitution criteria. Variations in contact finish, contact length specifications, insulation material composition, and insulation height fall within acceptable tolerance ranges for this connector category and do not preclude functional substitution in board-to-cable and board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

All three connector headers maintain active product status and satisfy core rectangular connector header specifications for 10-position, 0.156" pitch applications. Selection between the TE Connectivity 4-644992-0 and Molex substitutes (0026604100 and 0417910840) is based on the following engineering considerations:

TE Connectivity 4-644992-0: RoHS Compliant status with thermoplastic glass-filled insulation material and tin contact finish at 150.0µin thickness. Insulation height of 0.545" (13.84mm) and contact post length of 0.125" (3.18mm) establish specific board-level clearance and mating depth characteristics.

Molex 0026604100: ROHS3 Compliant status with polyester glass-filled insulation material and tin contact finish at 60.0µin thickness. Reduced insulation height of 0.446" (11.33mm) and extended contact post length of 0.140" (3.56mm) accommodate different PCB stack-up configurations. Tin finish on both mating and post contacts provides corrosion resistance equivalent to the primary part.

Molex 0417910840: ROHS3 Compliant status with polyester glass-filled insulation material and gold contact finish on mating surfaces at 15.0µin thickness. Extended contact post length of 0.140" (3.56mm) and tin post finish at 100.0µin thickness. Gold mating finish provides enhanced contact reliability in low-signal-level applications and corrosive environments.

All three parts carry UL94 V-0 flammability rating, MSL 1 (Unlimited) moisture sensitivity, and EAR99 export classification. Compliance with RoHS and REACH regulations is confirmed for all options.

Frequently Asked Questions (FAQ)

Q: Can Molex 0026604100 or 0417910840 be used as direct replacements for TE Connectivity 4-644992-0 in existing designs?

A: Both Molex parts satisfy the core mating parameters (10 positions, 0.156" pitch, shrouded single-wall header, through-hole solder termination, friction lock fastening). Mechanical and electrical interchangeability is established. Design verification is required to confirm compatibility with specific board-level clearances and mating depth requirements, as insulation height and contact post length differ between the TE part and Molex substitutes.

Q: What is the difference between the two Molex substitute options?

A: Molex 0026604100 features tin contact finish on mating surfaces at 60.0µin thickness. Molex 0417910840 features gold contact finish on mating surfaces at 15.0µin thickness with increased tin thickness on post contacts (100.0µin). Gold finish provides enhanced corrosion resistance and contact reliability in demanding environments. Both parts share identical pitch, position count, shrouding, and mounting characteristics.

Q: Are there differences in insulation material between the primary part and substitutes?

A: TE Connectivity 4-644992-0 uses thermoplastic glass-filled insulation material with black color. Both Molex substitutes use polyester glass-filled insulation material with natural color. Both material compositions carry UL94 V-0 flammability rating. Material selection does not affect electrical or mechanical substitution eligibility.

Q: How do contact finish specifications impact part selection?

A: Contact finish thickness and composition affect corrosion resistance, contact resistance stability, and performance in specific environmental conditions. TE Connectivity 4-644992-0 provides 150.0µin tin finish on both mating and post contacts. Molex 0026604100 provides 60.0µin tin finish on both surfaces. Molex 0417910840 provides 15.0µin gold finish on mating contacts and 100.0µin tin finish on post contacts. Gold finish (0417910840) is specified for applications requiring enhanced contact reliability and corrosion resistance.

Q: What are the implications of different insulation heights?

A: TE Connectivity 4-644992-0 has insulation height of 0.545" (13.84mm). Both Molex substitutes have insulation height of 0.446" (11.33mm). Insulation height determines the vertical profile of the connector on the PCB. Design verification is required to confirm that reduced insulation height does not conflict with adjacent board components or assembly constraints.

Q: Are all three parts RoHS compliant?

A: TE Connectivity 4-644992-0 carries RoHS Compliant status. Both Molex parts carry ROHS3 Compliant status. Both compliance levels satisfy RoHS directive requirements. ROHS3 represents the current regulatory standard.

Q: What is the inventory status of each part?

A: TE Connectivity 4-644992-0 has 966 pieces in stock. Molex 0026604100 has 12,663 pieces in stock. Molex 0417910840 has 2,371 pieces in stock. Inventory levels support production requirements across all three options.
