Substitute Part Grouping Explanation

Substitution between TE Connectivity 641963-2 and 641963-3 is based on electrical and mechanical parameter equivalence within the Universal MATE-N-LOK series. Both parts maintain identical specifications across the following critical parameters:

Electrical Compatibility Parameters:

• Contact type: Male Pin
• Number of positions: 2
• Pitch 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
• Termination method: Solder
• Shrouding: Shrouded - 4 Wall
• Insulation material: Polyamide (PA), Nylon
• Contact material: Phosphor Bronze
• Fastening type: Locking Ramp

Packaging Variation: The primary difference between these parts is packaging configuration and RoHS compliance status. The 641963-2 is supplied in standard packaging with RoHS non-compliant status, while the 641963-3 is supplied in bulk packaging with ROHS3 compliance. Contact finish on the post differs between tin-lead (641963-2) and tin (641963-3).

Parameter Comparison

Engineering Selection Recommendations

641963-2 Selection Criteria: The 641963-2 is appropriate for applications where RoHS non-compliance is acceptable or where legacy system compatibility with tin-lead post finishes is required. This part maintains active product status and is available in standard packaging configurations.

641963-3 Selection Criteria: The 641963-3 is the preferred selection for new designs and applications requiring ROHS3 compliance. The tin post finish on the 641963-3 provides environmental compliance benefits while maintaining functional equivalence to the tin-lead finish of the 641963-2. Bulk packaging of the 641963-3 supports high-volume production requirements. Both parts share identical electrical performance and mechanical interface specifications.

Compliance Consideration: Selection between these parts should account for regulatory requirements in the target application region. The 641963-3 ROHS3 compliance status aligns with current environmental regulations in the European Union and equivalent jurisdictions.

Frequently Asked Questions (FAQ)

Q: Are the 641963-2 and 641963-3 mechanically interchangeable?

A: Yes. Both connectors feature identical mounting type (through hole), shrouding configuration (shrouded - 4 wall), position count (2), and pitch spacing (0.250"). They mount identically on printed circuit boards and accept the same mating connectors.

Q: What is the functional difference between tin-lead and tin post finishes?

A: Both finishes provide solder termination capability. The tin finish on the 641963-3 eliminates lead content, meeting ROHS3 environmental compliance requirements. Functionally, both finishes support the same current rating (12A) and voltage rating (600VAC) specifications.

Q: Can I substitute 641963-3 for 641963-2 in existing designs?

A: Yes. The 641963-3 is electrically and mechanically equivalent to the 641963-2. Substitution is appropriate for new production runs and design revisions. The ROHS3 compliance of the 641963-3 provides additional regulatory alignment for current manufacturing standards.

Q: What does bulk packaging mean for the 641963-3?

A: Bulk packaging indicates the 641963-3 is supplied in larger quantity configurations without individual component packaging. This packaging method reduces material waste and is standard for high-volume manufacturing operations.

Q: Are both parts rated for the same electrical specifications?

A: Yes. Both the 641963-2 and 641963-3 maintain identical current rating (12A), voltage rating (600VAC), and operating temperature range (-40°C ~ 105°C). Electrical performance is equivalent across all specified parameters.

Q: Which part should I specify for new product designs?

A: The 641963-3 is recommended for new designs due to ROHS3 compliance status and current manufacturing alignment. Both parts are active products with full inventory availability.
