TE Connectivity 770565-2 WTB Terminal Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 770565-2 is a WTB Tin-Lead terminal connector designed for through-board, locking applications in the Mini Amp-In series. This component accommodates wire gauges from 18-22 AWG and features phosphor bronze contact material with tin-lead finish. The part is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector family, enabling component interchangeability in applications where specific finish requirements do not mandate the original part number.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 770565-2 terminal connector is determined by strict equivalence across the following critical parameters: wire gauge range (18-22 AWG), hole diameter tolerance (0.072" ~ 0.077"), insulation diameter range (0.060" ~ 0.110"), overall length (0.220"), terminal type (through board, locking), contact material (phosphor bronze), series designation (Mini Amp-In), and moisture sensitivity level (MSL 1). The substitute parts 3-770565-1 and 3-770565-2 maintain identical specifications across all mechanical and electrical parameters. The primary distinction between the main part and substitutes is the contact finish: the 770565-2 features tin-lead finish, while both substitute parts feature tin finish only. This finish variation does not alter the mechanical fit, electrical performance within the specified wire gauge range, or board-level compatibility. All parts share identical RoHS compliance status, packaging format, and environmental ratings.

Parameter Comparison

Engineering Selection Recommendations

All three parts—770565-2, 3-770565-1, and 3-770565-2—are classified as Active product status and maintain full compliance with RoHS regulations. The 770565-2 and 3-770565-1 both carry ROHS3 designation, while 3-770565-2 carries RoHS Compliant status. Selection between these parts should be based on contact finish requirements and inventory availability. The 770565-2 with tin-lead finish is appropriate for applications where tin-lead contact finish is specified. The 3-770565-1 and 3-770565-2 with tin finish are suitable for applications where tin finish meets electrical and environmental requirements. All parts share identical mechanical dimensions, wire gauge compatibility, and environmental ratings (MSL 1). Inventory levels are 5110 pieces for 770565-2, 50435 pieces for 3-770565-1, and 2400 pieces for 3-770565-2. Component selection should account for finish specification, compliance certification level, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can 3-770565-1 or 3-770565-2 be used as direct replacements for 770565-2?

A: Yes, both substitute parts maintain identical mechanical and electrical parameters including wire gauge range (18-22 AWG), hole diameter (0.072" ~ 0.077"), insulation diameter (0.060" ~ 0.110"), overall length (0.220"), terminal type (through board, locking), contact material (phosphor bronze), and moisture sensitivity level (MSL 1). The primary difference is contact finish: 770565-2 features tin-lead finish while 3-770565-1 and 3-770565-2 feature tin finish. Substitution is valid when tin finish meets application requirements.

Q: What is the difference between 3-770565-1 and 3-770565-2?

A: Both parts are identical in all mechanical and electrical specifications. The distinction lies in RoHS compliance designation: 3-770565-1 carries ROHS3 Compliant status while 3-770565-2 carries RoHS Compliant status. Inventory levels also differ: 3-770565-1 has 50435 pieces in stock while 3-770565-2 has 2400 pieces.

Q: Are these parts compatible with the same PCB hole sizes?

A: Yes. All three parts share identical hole diameter specifications of 0.072" ~ 0.077" (1.83mm ~ 1.96mm) and insulation diameter range of 0.060" ~ 0.110" (1.52mm ~ 2.79mm). PCB design and board-level compatibility are identical across all three part numbers.

Q: What wire gauges are supported by these terminal connectors?

A: All three parts support wire gauges from 18-22 AWG. This range is consistent across 770565-2, 3-770565-1, and 3-770565-2.

Q: Do these parts have any moisture sensitivity restrictions?

A: No. All three parts carry Moisture Sensitivity Level (MSL) rating of 1, which indicates unlimited shelf life and no special moisture control requirements during storage or handling.

Q: What is the packaging format for these terminal connectors?

A: All three parts are supplied in Cut Tape (CT) packaging format, enabling automated component placement and consistent handling across production environments.

Q: Are all three parts currently available for purchase?

A: Yes. All three parts maintain Active product status. Inventory availability is 5110 pieces for 770565-2, 50435 pieces for 3-770565-1, and 2400 pieces for 3-770565-2.
