Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 770190-1 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• 15-position connector with 3-row configuration
• 0.163" (4.14mm) mating pitch and row spacing
• Through-hole mounting with solder termination
• Shrouded 4-wall design with locking ramp fastening
• Insulation height of 0.531" (13.50mm)

Electrical Compatibility:

• Male pin contact type
• Brass contact material with circular contact shape
• 600VAC voltage rating
• Operating temperature range of -20°C to 85°C
• Contact finish thickness of 150.0µin (3.81µm)

Functional Equivalence:

• Board-to-cable/wire connection style
• General purpose applications
• Board lock feature
• All 15 positions loaded

The substitute part 1-770190-0 maintains identical mechanical and electrical specifications across all critical parameters. Variation exists only in contact finish composition and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1-770190-0 serves as a direct functional equivalent to the 770190-1 across all mechanical and electrical parameters. Both connectors maintain identical mating pitch, row configuration, contact geometry, voltage rating, and operating temperature specifications.

The primary distinction between these parts is regulatory compliance status. The 770190-1 carries Last Time Buy status with RoHS non-compliant designation, while the 1-770190-0 maintains Active product status with ROHS3 compliance. This compliance difference reflects updated manufacturing processes that employ tin-only contact finish rather than tin-lead composition, while maintaining equivalent contact finish thickness and electrical performance.

For new designs and ongoing production requiring RoHS compliance, the 1-770190-0 is the appropriate selection. For legacy systems or applications where RoHS compliance is not a requirement, either part satisfies the functional specification. The 1-770190-0 offers superior long-term availability due to its Active product status.

Frequently Asked Questions (FAQ)

Q: Are the 770190-1 and 1-770190-0 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 15-position configuration, 0.163" (4.14mm) pitch, 3-row layout, through-hole mounting, shrouded 4-wall design, and locking ramp fastening. PCB footprints and mating interface dimensions are identical.

Q: What is the difference in contact finish between these parts?

A: The 770190-1 uses tin-lead contact finish, while the 1-770190-0 uses tin-only finish. Both maintain 150.0µin (3.81µm) finish thickness. This difference reflects RoHS compliance requirements; tin-only finish is compliant with ROHS3 standards.

Q: Can I use the 1-770190-0 as a replacement for the 770190-1 in existing designs?

A: Yes. The 1-770190-0 is electrically and mechanically equivalent. The tin-only contact finish provides equivalent electrical performance and reliability. Substitution is appropriate for both new production and field service applications.

Q: Why is the 770190-1 marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued this product variant. The 1-770190-0 represents the current production equivalent with updated compliance specifications.

Q: Are there any voltage or current rating differences?

A: No. Both connectors maintain 600VAC voltage rating and current capacity that varies by wire gauge. Electrical performance specifications are identical.

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

A: Both the 770190-1 and 1-770190-0 operate across -20°C to 85°C temperature range with UL94 V-0 flammability rating.

Q: Is the 1-770190-0 available in higher quantities than the 770190-1?

A: Yes. The 1-770190-0 maintains Active product status with 3432 pieces in stock, compared to the 770190-1 Last Time Buy status with 1212 pieces available. The 1-770190-0 offers superior long-term availability.

Q: Do both connectors require the same mating connector?

A: Yes. Both headers are compatible with identical Mini-Universal MATE-N-LOK series receptacle connectors. Mating interface specifications are identical.

Q: What is the Moisture Sensitivity Level for these connectors?

A: Both connectors carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
