Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 770252-2 is determined by strict equivalence across the following parameters:

• Series Compatibility: Part must belong to the Universal MATE-N-LOK II series
• Contact Configuration: Split pin contact type required
• Termination Method: Crimp termination only
• Wire Gauge Range: 18-24 AWG capacity
• Contact Finish: Gold plating with 30.0µin (0.76µm) thickness
• Moisture Sensitivity: MSL 1 (Unlimited) classification

The substitute part 1-770252-0 meets all specified parameters and is classified as active, providing a direct functional replacement for the obsolete 770252-2.

Parameter Comparison

Engineering Selection Recommendations

The part 1-770252-0 is the direct equivalent for 770252-2. Selection of 1-770252-0 is based on the following factors:

Product Status: The 770252-2 is obsolete. The 1-770252-0 is active and maintains full production availability, ensuring supply chain continuity.

Electrical and Mechanical Equivalence: All critical parameters—series designation, contact type, termination method, wire gauge range, contact finish, and finish thickness—are identical between the two parts.

Compliance Enhancement: The 1-770252-0 carries ROHS3 compliance certification, whereas the 770252-2 status is not applicable. This represents an improvement in regulatory alignment for new designs and procurement cycles.

Packaging Consideration: The 1-770252-0 is supplied in bulk packaging, which may differ from the original 770252-2 packaging specification. Bulk packaging does not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can 1-770252-0 be used as a direct replacement for 770252-2 in existing assemblies?

A: Yes. The 1-770252-0 is electrically and mechanically equivalent to 770252-2. All contact specifications, wire gauge compatibility, and termination characteristics are identical. The parts are interchangeable in applications designed for the Universal MATE-N-LOK II series.

Q: What is the difference between the two part numbers?

A: The primary difference is product status. The 770252-2 is obsolete, while 1-770252-0 is active. The 1-770252-0 also carries ROHS3 compliance certification. Functionally, both parts are identical.

Q: Does the bulk packaging of 1-770252-0 affect compatibility?

A: No. Packaging format does not affect the electrical or mechanical performance of the contact. Bulk packaging is a supply and handling consideration only.

Q: Are there any wire gauge limitations when substituting?

A: No. Both parts support the same wire gauge range of 18-24 AWG. Substitution does not introduce any wire gauge restrictions.

Q: What is the significance of the 30.0µin gold finish thickness?

A: The 30.0µin (0.76µm) gold plating thickness is maintained on both parts. This specification ensures consistent contact resistance, corrosion resistance, and electrical performance across both components.

Q: Is the Moisture Sensitivity Level the same for both parts?

A: Yes. Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity constraints during storage or handling.
