TE Connectivity AMP Connectors 644948-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 644948-1 is an active rectangular connector header designed for through-hole mounting applications. This vertical connector accommodates 6 positions at 0.156" (3.96mm) pitch and is configured for board-to-cable/wire connections with solder termination. The connector features shrouded design with friction lock fastening and operates across industrial and general-purpose applications. Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when inventory constraints require component alternatives that maintain equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 644948-1 with the Molex 0026481061 is based on alignment of the following critical parameters:

Matching Parameters:

• Connector Type: Both are headers with male pin contacts
• Pitch - Mating: Both operate at 0.156" (3.96mm) pitch
• Number of Positions: Both accommodate 6 positions in a single row
• Mounting Type: Both utilize through-hole mounting
• Termination: Both employ solder termination
• Material Flammability Rating: Both meet UL94 V-0 standard
• Moisture Sensitivity Level: Both rated at MSL 1 (Unlimited)
• ECCN Classification: Both classified as EAR99
• HTSUS Code: Both classified under 8536.69.4040

Differing Parameters: The substitute part exhibits variations in shrouding design (unshrouded versus shrouded), fastening mechanism (push-pull versus friction lock), contact geometry (square versus circular), insulation material composition, and contact dimensions. These differences require evaluation within the specific application context to determine functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 644948-1 and Molex 0026481061 maintain active product status and comply with RoHS requirements, confirming ongoing manufacturer support and environmental compliance. Both connectors achieve UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating, indicating suitability for standard industrial and general-purpose applications without specialized environmental controls.

The TE Connectivity 644948-1 provides specified voltage and temperature ratings (600VAC, -55°C to 105°C), establishing defined performance boundaries for applications requiring explicit electrical parameter documentation. The Molex 0026481061 does not provide published voltage and temperature specifications in the available data.

Dimensional variations exist between the two connectors, particularly in insulation height (0.425" versus 0.128"), overall contact length (0.700" versus 0.750"), and contact mating length (0.400" versus 0.450"). These differences may affect board layout compatibility, mating interface geometry, and mechanical clearance requirements in confined spaces.

The TE Connectivity connector features shrouded design with friction lock fastening, while the Molex connector is unshrouded with push-pull fastening. Shrouding provides mechanical protection and keying functionality; friction lock fastening provides positive retention without additional mechanical engagement. These design differences influence connector robustness in vibration-prone environments and ease of mating/unmating operations.

Selection between these connectors requires verification that dimensional differences, shrouding characteristics, and fastening mechanisms align with specific application requirements and PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: What are the primary criteria for substituting the TE Connectivity 644948-1 with the Molex 0026481061?

A: Both connectors share identical pitch (0.156"/3.96mm), position count (6), row configuration (1), mounting method (through-hole), and termination type (solder). Both achieve UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating. These aligned parameters establish the foundation for substitution consideration.

Q: How do the dimensional differences between these connectors affect compatibility?

A: The Molex connector exhibits greater overall contact length (0.750" versus 0.700") and mating contact length (0.450" versus 0.400"), while the TE Connectivity connector provides greater insulation height (0.425" versus 0.128"). These differences impact PCB layout spacing, mating interface depth, and clearance to adjacent components. Application-specific verification is required to confirm dimensional compatibility.

Q: What is the significance of shrouding differences between these connectors?

A: The TE Connectivity connector features shrouded design with one wall, providing mechanical protection and keying functionality to prevent incorrect mating orientation. The Molex connector is unshrouded, offering reduced profile and simplified mating but without mechanical keying protection. Application requirements for mating security and environmental protection determine the relevance of this difference.

Q: How do the fastening mechanisms differ between these connectors?

A: The TE Connectivity connector employs friction lock fastening, which provides positive retention through mechanical interference without additional engagement steps. The Molex connector uses push-pull fastening, requiring deliberate mechanical action for mating and unmating. Vibration environment severity and operator interface requirements influence the appropriateness of each fastening approach.

Q: Are voltage and temperature ratings equivalent between these connectors?

A: The TE Connectivity connector specifies 600VAC voltage rating and -55°C to 105°C operating temperature range. The Molex connector does not provide published voltage or temperature specifications in available documentation. Applications requiring explicit electrical parameter verification must reference the TE Connectivity connector specifications or obtain supplemental Molex technical documentation.

Q: What packaging considerations apply to these connectors?

A: Both connectors are supplied in bulk packaging. The TE Connectivity connector has 964 pieces in current inventory with 5 positions loaded. The Molex connector has 1419 pieces in current inventory with all positions loaded. Inventory availability and position loading configuration may influence procurement decisions based on application requirements and assembly processes.

Q: Do both connectors meet current environmental compliance standards?

A: The TE Connectivity connector is RoHS Compliant. The Molex connector is ROHS3 Compliant. Both meet current regulatory requirements for hazardous substance restriction. REACH status for the TE Connectivity connector is listed as vendor undefined; REACH status for the Molex connector is not specified in available data.
