Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 770968-2 connector is determined by strict alignment of core electrical and mechanical parameters. The following criteria establish substitution validity:

Critical Matching Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (4)
• Number of rows (2)
• Pitch spacing (0.163" / 4.14mm)
• Row spacing (0.163" / 4.14mm)
• Mounting configuration (Through Hole, Right Angle)
• Shrouding design (Shrouded - 4 Wall)
• Termination method (Solder)
• Voltage rating (600VAC)
• Series designation (Mini-Universal MATE-N-LOK)

The identified substitute parts 1-770968-1 and 770968-1 maintain identical mechanical interfaces and electrical ratings. Variations in contact finish specifications and product status do not affect functional interchangeability in board-level applications where the connector geometry and electrical performance are the determining factors.

Parameter Comparison

Engineering Selection Recommendations

1-770968-1 Selection Criteria:

The 1-770968-1 represents the primary substitute option for the 770968-2. This part maintains full mechanical and electrical compatibility with identical pitch spacing, mounting configuration, and voltage rating. The 1-770968-1 carries Active product status, ensuring ongoing availability and supply chain stability. This part achieves ROHS3 compliance, meeting current regulatory requirements for new designs and manufacturing environments with RoHS mandates. The operating temperature range of -20°C to 105°C matches the main part specification. Contact finish differences (gold mating surface with tin post finish versus tin-lead post finish on the main part) do not affect functional interchangeability in standard board-level applications.

770968-1 Selection Criteria:

The 770968-1 serves as a secondary substitute option. This part maintains identical mechanical geometry and electrical ratings but carries Last Time Buy status, similar to the main part. The operating temperature range is reduced to -20°C to 85°C, which may limit suitability for applications requiring the full 105°C upper temperature specification. Contact finish specifications differ from the main part (tin-lead mating surface with tin-lead post finish). RoHS compliance status is not defined by the vendor. This part should be selected only when the reduced temperature range is acceptable and when supply availability aligns with project timelines.

Compliance Considerations:

For new designs or manufacturing environments subject to RoHS regulations, the 1-770968-1 is the appropriate selection. For legacy applications or environments without RoHS mandates, either substitute part is functionally equivalent to the main part.

Frequently Asked Questions (FAQ)

Q: Can 1-770968-1 be used as a direct replacement for 770968-2 in existing designs?

A: Yes. The 1-770968-1 maintains identical mechanical and electrical specifications including pitch spacing (0.163"), mounting type (through-hole right-angle), shrouding configuration (4-wall), and voltage rating (600VAC). The parts are mechanically and electrically interchangeable at the board level.

Q: What is the difference between 1-770968-1 and 770968-1?

A: Both parts are mechanically compatible with the main part 770968-2. The primary differences are: (1) 1-770968-1 carries Active product status and ROHS3 compliance, while 770968-1 is Last Time Buy with undefined RoHS status; (2) 1-770968-1 supports the full -20°C to 105°C operating temperature range, while 770968-1 is limited to -20°C to 85°C; (3) contact finish specifications differ between the two parts.

Q: Why does the 770968-1 have a reduced operating temperature range?

A: The 770968-1 specifies -20°C to 85°C maximum operating temperature, compared to -20°C to 105°C for the main part and 1-770968-1. This specification difference is provided in the part data and must be considered for applications requiring operation at elevated temperatures above 85°C.

Q: Is the 1-770968-1 suitable for new product designs?

A: Yes. The 1-770968-1 is the recommended choice for new designs. It carries Active product status, ensuring long-term availability, and achieves ROHS3 compliance, meeting current regulatory requirements for manufacturing and distribution in regulated markets.

Q: Are there any compatibility issues with PCB layouts designed for 770968-2?

A: No. All three parts (770968-2, 1-770968-1, and 770968-1) share identical pitch spacing (0.163"), row spacing (0.163"), mounting type (through-hole right-angle), and shrouding configuration. PCB layouts designed for 770968-2 accommodate both substitute parts without modification.

Q: What is the significance of the contact finish differences?

A: Contact finish variations (gold versus tin-lead on mating surfaces, and tin versus tin-lead on post surfaces) do not affect functional interchangeability in standard board-level solder applications. These differences reflect manufacturing process variations and do not impact electrical performance or mechanical fit.

Q: Should I stock 770968-1 given its Last Time Buy status?

A: The 770968-1 carries Last Time Buy status, indicating discontinued production. For long-term supply security, the 1-770968-1 (Active status) is the preferred choice. The 770968-1 should be selected only if current inventory availability aligns with immediate project requirements and no long-term supply is needed.
