TE Connectivity 770254-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 770254-2 is a pin contact for rectangular connectors in the Universal MATE-N-LOK II series. This component is a crimp-style gold-plated pin contact rated for 14-20 AWG wire gauges. The part is classified as obsolete, necessitating identification of active equivalent components for ongoing procurement and system maintenance. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct interchangeability in existing connector assemblies.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 770254-2 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part 1-770254-0 qualifies as a direct equivalent because it maintains identical specifications in the following key areas:

• Series designation: Universal MATE-N-LOK II
• Contact configuration: Pin contact
• Termination technology: Crimp
• Wire gauge compatibility: 14-20 AWG
• Contact finish material and thickness: Gold at 30.0µin (0.76µm)
• Regulatory compliance: ROHS3 Compliant
• Moisture sensitivity classification: MSL 1 (Unlimited)

The substitute part differs only in product status (active versus obsolete) and packaging configuration (bulk versus original packaging), neither of which affects functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

The part 1-770254-0 is the direct substitute for the obsolete 770254-2. Selection of this active component is supported by the following engineering criteria:

Product Status: The substitute part maintains active production status, ensuring continued availability and supply chain reliability. The obsolete status of 770254-2 creates procurement risk for new applications and system maintenance.

Regulatory Compliance: Both parts carry identical ROHS3 compliance certification, confirming adherence to current environmental and hazardous substance restrictions. This equivalence eliminates compliance verification requirements for system-level certifications.

Electrical and Mechanical Specifications: All functional parameters are identical, including wire gauge range, contact finish material, finish thickness, and termination method. This equivalence guarantees direct interchangeability without circuit redesign or connector assembly modification.

Moisture Sensitivity: Both parts carry MSL 1 classification, indicating unlimited shelf life and identical handling requirements throughout the supply chain and assembly process.

Frequently Asked Questions (FAQ)

Q: Can 1-770254-0 be used as a direct replacement for 770254-2 in existing connector assemblies?

A: Yes. The parts are electrically and mechanically equivalent across all specified parameters. Direct substitution is supported without modification to connector housings, mating interfaces, or wire termination procedures.

Q: What is the difference between 770254-2 and 1-770254-0?

A: The parts are functionally identical. The primary differences are product status (obsolete versus active) and packaging format (original versus bulk). These differences do not affect component performance or interchangeability.

Q: Are there any wire gauge limitations when substituting 1-770254-0 for 770254-2?

A: No. Both parts support the identical wire gauge range of 14-20 AWG. Crimp tool specifications and wire preparation procedures remain unchanged.

Q: Does the bulk packaging of 1-770254-0 affect its performance compared to 770254-2?

A: No. Packaging format does not influence electrical or mechanical performance. Bulk packaging affects only procurement quantity and handling procedures, not component functionality.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both 770254-2 and 1-770254-0 carry ROHS3 compliance certification, confirming conformance to current hazardous substance restrictions.

Q: What is the contact finish thickness specification for both parts?

A: Both parts specify a gold contact finish thickness of 30.0µin (0.76µm), ensuring identical electrical contact resistance and corrosion resistance characteristics.

Q: Is there any difference in moisture sensitivity handling between these parts?

A: No. Both parts carry MSL 1 classification, indicating unlimited shelf life and identical storage and handling requirements.
