Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector headers is determined by strict equivalence across electrical and mechanical parameters. The following criteria establish functional interchangeability:

Critical Matching Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions and rows (8 positions, 2 rows)
• Pitch and row spacing (0.163" / 4.14mm)
• Mounting configuration (Through Hole, Right Angle)
• Shrouding design (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening mechanism (Locking Ramp)
• Voltage and temperature ratings (600VAC, -20°C ~ 85°C)
• Flammability compliance (UL94 V-0)
• Series designation (Mini-Universal MATE-N-LOK)

The substitute part 1-770970-0 maintains identical specifications across all critical parameters, with the exception of contact finish composition and product status. This part is functionally equivalent for board-to-cable/wire applications requiring 8-position right-angle headers with 4.14mm pitch spacing.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1-770970-0 provides functional equivalence to the 770970-1 across all critical electrical and mechanical parameters required for board-to-cable/wire connector applications. Both parts maintain identical pitch spacing, row configuration, mounting orientation, and environmental ratings.

Product Status Consideration: The 770970-1 carries Last Time Buy status, indicating end-of-life manufacturing. The 1-770970-0 maintains Active product status with current inventory availability (2,300 pieces), establishing it as the appropriate long-term component selection for ongoing production requirements.

Compliance Differentiation: The 1-770970-0 achieves ROHS3 compliance, whereas the 770970-1 is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the 1-770970-0 is the mandated selection. For legacy systems or applications without RoHS constraints, both parts remain electrically and mechanically interchangeable.

Contact Finish Variation: The 770970-1 specifies Tin-Lead contact finish, while the 1-770970-0 specifies Tin finish. Both maintain identical finish thickness (150.0µin / 3.81µm) and contact material (Brass). This variation reflects manufacturing process updates and does not affect electrical performance or mechanical compatibility in standard applications.

Frequently Asked Questions (FAQ)

Q: Are the 770970-1 and 1-770970-0 mechanically interchangeable in existing designs?

A: Yes. Both parts maintain identical pitch spacing (0.163" / 4.14mm), row configuration (2 rows, 8 positions), mounting type (through-hole right angle), and shrouding design (4-wall shrouded). PCB footprints and mating connector interfaces are identical.

Q: What is the primary reason to transition from 770970-1 to 1-770970-0?

A: The 770970-1 is designated Last Time Buy, indicating discontinued manufacturing. The 1-770970-0 maintains Active status with current production and inventory availability, ensuring component supply continuity.

Q: Does the contact finish change from Tin-Lead to Tin affect electrical performance?

A: No. Both finishes maintain identical thickness (150.0µin / 3.81µm) and are applied to brass contact material. The finish change reflects manufacturing process evolution and does not alter electrical conductivity, voltage rating (600VAC), or current-carrying capacity.

Q: Is the 1-770970-0 suitable for applications requiring RoHS compliance?

A: Yes. The 1-770970-0 is ROHS3 compliant. The 770970-1 is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the 1-770970-0 is the required selection.

Q: Are there any temperature or voltage rating differences between these parts?

A: No. Both parts operate across -20°C to 85°C and maintain a 600VAC voltage rating. Operating temperature range and voltage specifications are identical.

Q: What is the current inventory status for each part?

A: The 770970-1 has 143,049 pieces in stock (Last Time Buy status). The 1-770970-0 has 2,300 pieces in stock (Active status). For new designs and ongoing production, the 1-770970-0 is recommended due to active manufacturing support.

Q: Can these parts be used interchangeably in board-to-cable/wire applications?

A: Yes. Both parts are designed for identical board-to-cable/wire connection styles with solder termination and locking ramp fastening. Mating connector compatibility is maintained across both part numbers.

Q: Are there any differences in the shrouding or fastening mechanisms?

A: No. Both parts feature identical 4-wall shrouding and locking ramp fastening type. Board lock features are present on both parts.
