TE Connectivity 770875-1 Rectangular Connector: Equivalent & Substitute Parts

Part Overview

The TE Connectivity 770875-1 is a shrouded vertical header connector from the Mini-Universal MATE-N-LOK series, designed for board-to-cable/wire applications. This connector features 6 positions arranged in 2 rows with 0.163" (4.14mm) pitch spacing and through-hole solder termination. The part is currently discontinued at DiGi Electronics, necessitating identification of equivalent and substitute components that maintain functional compatibility for existing designs and new production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connectors is determined by strict alignment of electrical and mechanical parameters. For the TE Connectivity 770875-1, substitute parts must satisfy the following criteria:

Direct Equivalents maintain identical or functionally equivalent specifications across all critical parameters: connector type, contact type, number of positions, row configuration, mating pitch, row spacing, mounting method, termination type, shrouding design, and fastening mechanism. Contact finish composition differences (Tin-Lead versus Tin) do not preclude functional equivalence when all other parameters align.

Similar Substitutes share the same functional connector category and mounting approach but may exhibit variations in specific parameters such as mating pitch tolerance, contact post length, insulation height, contact shape, or contact finish thickness. These variations require engineering evaluation to confirm compatibility with the application's mechanical and electrical constraints.

The following parameters are critical for determining substitution eligibility:

• Mating pitch and row spacing
• Number of positions and row arrangement
• Mounting type and termination method
• Shrouding configuration and fastening type
• Voltage and temperature ratings
• Flammability compliance

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 1-770875-0 is the primary direct equivalent for the discontinued 770875-1. Both connectors are manufactured by TE Connectivity within the same Mini-Universal MATE-N-LOK series and share identical mechanical and electrical specifications including mating pitch, row spacing, contact post length, and insulation height. The 1-770875-0 is currently active in production with 3400 units in stock, providing immediate availability. The contact finish differs from Tin-Lead to Tin; however, this change aligns with modern RoHS3 compliance requirements. The 1-770875-0 maintains the same UL94 V-0 flammability rating, operating temperature range, and board lock features as the original part.

Molex 0039299067 functions as a similar substitute within the Mini-Fit Jr 5566 series. This connector maintains the same connector type, contact type, position count, row configuration, through-hole mounting, solder termination, shrouding design, and locking ramp fastening. However, the mating pitch and row spacing differ at 0.165" (4.20mm) compared to 0.163" (4.14mm) on the original part. The contact post length is shorter at 0.138" (3.50mm) versus 0.175" (4.45mm), and the insulation height is reduced to 0.504" (12.80mm). The contact shape transitions from circular to square, and the contact finish thickness is significantly reduced to 35.4µin (0.90µm). These dimensional and geometric variations require verification of mechanical compatibility with the mating connector and printed circuit board layout before implementation. The 0039299067 is active in production with 24180 units in stock and carries ROHS3 compliance and UL94 V-0 flammability rating.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-770875-0 be used as a direct replacement for the 770875-1?

A: Yes. The 1-770875-0 is a direct equivalent with identical mechanical and electrical specifications. Both connectors feature 6 positions in 2 rows with 0.163" (4.14mm) mating pitch and row spacing, through-hole solder termination, shrouded 4-wall design, and locking ramp fastening. The primary difference is the contact finish composition, which has transitioned from Tin-Lead to Tin to comply with RoHS3 standards. This change does not affect functional compatibility.

Q: What are the key differences between the TE Connectivity 770875-1 and the Molex 0039299067?

A: The primary differences are mating pitch and row spacing (0.165" versus 0.163"), contact post length (0.138" versus 0.175"), insulation height (0.504" versus 0.531"), contact shape (square versus circular), and contact finish thickness (35.4µin versus 150.0µin). These variations require confirmation that the mating connector and PCB layout accommodate the Molex connector's dimensional specifications.

Q: Is the Molex 0039299067 compatible with existing mating connectors designed for the 770875-1?

A: Compatibility depends on the specific mating connector and PCB design. The 0.002" (0.06mm) difference in mating pitch and row spacing may prevent proper mating with connectors designed for the 0.163" (4.14mm) pitch specification. The shorter contact post length and reduced insulation height must be verified against the application's mechanical constraints. Engineering evaluation is required before implementation.

Q: What is the difference in packaging between these connectors?

A: The TE Connectivity 770875-1 and 1-770875-0 are supplied in bulk packaging, while the Molex 0039299067 is supplied in tray packaging. Packaging format may affect handling, storage, and assembly processes but does not impact electrical or mechanical functionality.

Q: Are all three connectors RoHS compliant?

A: The TE Connectivity 770875-1 is RoHS Compliant. The TE Connectivity 1-770875-0 is ROHS3 Compliant. The Molex 0039299067 is ROHS3 Compliant and REACH Unaffected. All three connectors meet current regulatory compliance standards for their respective product statuses.

Q: What is the operating temperature range for the Molex 0039299067?

A: The operating temperature range for the Molex 0039299067 is not specified in the available technical data. The TE Connectivity 770875-1 and 1-770875-0 both operate across -20°C to 85°C. Confirmation of the Molex connector's thermal specifications is recommended for applications with temperature-critical requirements.

Q: Can the contact finish difference between Tin-Lead and Tin affect soldering performance?

A: Contact finish composition affects soldering characteristics and long-term reliability. The transition from Tin-Lead to Tin in the 1-770875-0 reflects modern manufacturing standards and RoHS3 compliance. Both finishes are suitable for solder termination; however, soldering parameters and thermal profiles may require adjustment based on the specific finish composition and thickness.
