Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 770182-2 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Connector pitch (0.163" / 4.14mm mating pitch)
• Number of positions (9 positions)
• Row configuration (3 rows with 0.163" row spacing)
• Contact type (male pin)
• Voltage rating (600VAC minimum)
• Operating temperature range (-20°C to 105°C minimum)

Mechanical Compatibility Parameters:

• Connector series (Mini-Universal MATE-N-LOK)
• Mounting type (through hole)
• Shrouding configuration (shrouded 4-wall design)
• Insulation material (polyamide/nylon)
• Contact material (brass)
• Fastening type (locking ramp)

Physical Compatibility Parameters:

• Insulation height (0.531" / 13.50mm)
• Contact post length (0.175" / 4.45mm)
• Contact shape (circular)
• Insulation color (white)

The substitute part 1-770182-1 maintains full equivalence across all critical parameters, with the exception of post-termination contact finish composition and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1-770182-1 serves as a direct functional substitute for the 770182-2 across all critical electrical and mechanical parameters. Both connectors maintain identical pitch, position count, row configuration, voltage rating, and operating temperature specifications. The connectors are mechanically and electrically interchangeable within the Mini-Universal MATE-N-LOK series.

The primary distinction between these parts relates to product lifecycle status and regulatory compliance. The 770182-2 carries Last Time Buy status, indicating discontinued production. The 1-770182-1 maintains Active product status with current manufacturing availability. Additionally, the 1-770182-1 carries RoHS Compliant certification, whereas the 770182-2 is marked as Not applicable for RoHS status. The contact finish on the post differs between the two parts: the 770182-2 uses Tin-Lead while the 1-770182-1 uses Tin composition.

For new designs or applications requiring long-term component availability, the 1-770182-1 is the appropriate selection. For legacy system maintenance where original specifications must be preserved, the 770182-2 remains functionally equivalent where inventory permits.

Frequently Asked Questions (FAQ)

Q: Are the 770182-2 and 1-770182-1 connectors mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including pitch (0.163"), position count (9), row configuration (3 rows), shrouding design (4-wall), and mounting type (through hole). They are mechanically interchangeable within the Mini-Universal MATE-N-LOK series.

Q: Are the 770182-2 and 1-770182-1 connectors electrically interchangeable?

A: Yes. Both connectors maintain identical electrical specifications including voltage rating (600VAC), operating temperature range (-20°C to 105°C), contact material (brass), and mating contact finish (gold plated). They are electrically interchangeable for general purpose applications.

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

A: The 770182-2 features Tin-Lead post termination finish, while the 1-770182-1 features Tin post termination finish. Both maintain identical mating contact finish (gold plated at 30.0µin thickness). This difference reflects regulatory evolution toward lead-free manufacturing practices.

Q: Why does the 770182-2 show Last Time Buy status?

A: Last Time Buy status indicates the manufacturer has discontinued production of this part number. The 1-770182-1 is the active replacement part number with current manufacturing support and availability.

Q: What is the significance of RoHS compliance difference between these parts?

A: The 1-770182-1 carries RoHS Compliant certification, confirming compliance with Restriction of Hazardous Substances regulations. The 770182-2 is marked as Not applicable, reflecting its earlier design and discontinuation status. For applications subject to RoHS requirements, the 1-770182-1 is the appropriate selection.

Q: Can I use the 1-770182-1 as a direct replacement in existing assemblies using the 770182-2?

A: Yes. The 1-770182-1 is a direct functional replacement. Both connectors are mechanically and electrically equivalent across all critical parameters. The primary consideration is the post termination finish composition change from Tin-Lead to Tin.

Q: Are there any packaging differences between these connectors?

A: Both parts are supplied in Bulk packaging. The 770182-2 shows 1132 pieces in stock inventory, while the 1-770182-1 shows 3600 pieces in stock inventory. Packaging format and unit quantities per package are not specified in the provided data.

Q: What applications are these connectors suitable for?

A: Both connectors are rated for General Purpose applications. The 600VAC voltage rating, UL94 V-0 flammability rating, and -20°C to 105°C operating temperature range support use in industrial control, instrumentation, and general electrical interconnect applications.

Q: How do I determine which part to specify for a new design?

A: For new designs, specify the 1-770182-1. This part maintains Active product status, current manufacturing availability, and RoHS compliance. The 770182-2 should only be specified for legacy system maintenance where original part compatibility is required and inventory is available.
