TE Connectivity 641970-2 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 641970-2 is a shrouded vertical rectangular connector header from the Universal MATE-N-LOK series. This through-hole mounted component features 6 positions arranged in 3 rows with 0.250" (6.35mm) pitch spacing, designed for board-to-cable/wire applications. The connector utilizes male pin contacts with gold-plated mating surfaces and tin-lead plated posts for solder termination.

The 641970-2 is an active product with 1059 units currently in stock. Substitute parts are identified based on identical electrical and mechanical specifications while accounting for variations in packaging, compliance certifications, and contact finish materials on the post termination.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 641970-2 is determined by matching the following critical parameters:

Electrical Compatibility Parameters:

• Contact type (Male Pin)
• Number of positions (6)
• Row configuration (3 rows)
• Mating pitch (0.250" / 6.35mm)
• Row spacing (0.250" / 6.35mm)
• Current rating (12A)
• Voltage rating (600VAC)
• Operating temperature range (-40°C ~ 105°C)

Mechanical Compatibility Parameters:

• Connector type (Header)
• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Contact material (Phosphor Bronze)
• Insulation material (Polyamide/Nylon)
• Mating contact finish (Gold)

Allowable Variations:

• Packaging format (tape/reel versus bulk)
• Contact finish on post termination (Tin-Lead versus Tin)
• RoHS compliance status
• REACH compliance designation

The substitute part 641970-3 maintains identical electrical and mechanical specifications while differing in packaging (bulk), post contact finish (Tin instead of Tin-Lead), and regulatory compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 641970-2 and 641970-3 are active products from TE Connectivity's Universal MATE-N-LOK series and are functionally interchangeable for applications requiring a 6-position, 0.250" pitch shrouded header connector with through-hole solder termination.

Selection based on regulatory requirements:

The 641970-3 is ROHS3 compliant, making it the appropriate selection for applications subject to RoHS3 regulations or where lead-free solder compatibility is required. The post contact finish difference (Tin versus Tin-Lead) reflects this compliance distinction.

The 641970-2 maintains the original tin-lead post finish and is non-compliant with RoHS regulations. This part remains suitable for applications without RoHS compliance mandates or where legacy tin-lead solder processes are specified.

Selection based on packaging:

The 641970-2 is supplied in standard packaging format. The 641970-3 is supplied in bulk packaging, which may affect procurement logistics and minimum order quantities depending on supplier inventory policies.

Both parts maintain identical electrical performance, mechanical dimensions, and thermal operating characteristics. Selection between these parts should be based on regulatory compliance requirements and packaging format availability for the specific application and procurement context.

Frequently Asked Questions (FAQ)

Q: Are the 641970-2 and 641970-3 physically interchangeable on a printed circuit board?

A: Yes. Both connectors have identical mechanical dimensions, mounting hole patterns, and through-hole solder pad requirements. They are direct physical substitutes for PCB assembly applications.

Q: What is the difference between the Tin-Lead and Tin post finishes?

A: The 641970-2 features tin-lead plated posts, while the 641970-3 features tin-plated posts. This difference reflects RoHS3 compliance requirements. Both finishes are compatible with standard solder reflow processes, though the tin finish on the 641970-3 is lead-free compliant.

Q: Can I use the 641970-3 as a direct replacement for the 641970-2 in an existing design?

A: Yes, provided your application does not specifically require tin-lead solder compatibility or legacy material specifications. The 641970-3 is electrically and mechanically equivalent and offers improved regulatory compliance.

Q: What does "Shrouded - 4 Wall" mean?

A: This indicates the connector header has four walls of insulation material surrounding the contact positions, providing mechanical protection and preventing accidental contact with the male pins during handling and assembly.

Q: Are both parts suitable for 12A continuous current applications?

A: Yes. Both the 641970-2 and 641970-3 are rated for 12A continuous current and 600VAC voltage, making them suitable for general-purpose power distribution and signal applications within these electrical parameters.

Q: What is the operating temperature range for these connectors?

A: Both parts operate across the range of -40°C to 105°C, suitable for industrial and commercial applications with standard environmental temperature variations.

Q: Does packaging format affect electrical performance?

A: No. The difference between standard and bulk packaging is purely logistical and does not affect the electrical or mechanical performance of the connector. Packaging format selection depends on procurement volume requirements and supplier inventory availability.

Q: Are these connectors suitable for automated assembly?

A: Yes. Both connectors feature through-hole solder termination compatible with wave soldering and selective solder processes used in automated PCB assembly operations.
