Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector socket contacts is determined by strict alignment of electrical and mechanical parameters. The following criteria establish compatibility for the 770006-4:

Primary Substitution Criteria:

• Series compatibility: Universal MATE-N-LOK II
• Contact type: Socket
• Contact termination method: Crimp
• Wire gauge range: 14-20 AWG
• Contact finish: Gold
• Contact finish thickness: 30.0µin (0.76µm)
• Moisture sensitivity level: 1 (Unlimited)

Parts meeting all these parameters are classified as direct equivalents. Substitutes are identified based on matching electrical specifications and mechanical dimensions within the same connector series. Product status and compliance certifications are secondary factors that influence selection priority but do not alter functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 1-770006-0

The part 1-770006-0 is the direct equivalent to 770006-4 and is the preferred substitute. This part maintains identical electrical and mechanical specifications across all critical parameters including wire gauge, contact finish, finish thickness, and moisture sensitivity level. The 1-770006-0 carries Active product status and is ROHS3 compliant, providing compliance advantages for new designs and long-term availability. Packaging is specified as Cut Tape (CT), and inventory availability is substantially higher at 25,636 pieces.

Secondary Option: 770249-4

The part 770249-4 meets all functional substitution criteria with matching electrical and mechanical parameters. This part is classified as similar rather than direct due to a different base product number (770249 versus 770006). The 770249-4 is currently obsolete and carries RoHS status listed as not applicable. This part should be selected only when 1-770006-0 is unavailable, as it shares the same obsolescence status as the original 770006-4.

Compliance Considerations

For applications requiring RoHS3 compliance, 1-770006-0 is the only option among the three parts. The original 770006-4 and 770249-4 are both non-compliant or not applicable for RoHS requirements. REACH status differs across the parts; 1-770006-0 lists REACH status as vendor undefined, while both 770006-4 and 770249-4 are REACH affected.

Frequently Asked Questions (FAQ)

Q: Can 1-770006-0 be used as a direct replacement for 770006-4?

A: Yes. The 1-770006-0 is a direct equivalent. All electrical and mechanical parameters are identical, including wire gauge (14-20 AWG), contact finish (gold at 30.0µin thickness), termination method (crimp), and series compatibility (Universal MATE-N-LOK II). The primary differences are product status (active versus obsolete) and RoHS compliance (ROHS3 compliant versus non-compliant).

Q: What is the difference between 1-770006-0 and 770249-4?

A: Both parts meet the same functional substitution criteria with identical electrical and mechanical specifications. The primary difference is the base product number: 1-770006-0 uses base number 770006, while 770249-4 uses base number 770249. Both are socket contacts for the Universal MATE-N-LOK II series with 14-20 AWG wire gauge and gold plating. The 1-770006-0 is active and ROHS3 compliant, while 770249-4 is obsolete.

Q: Does packaging affect substitution compatibility?

A: Packaging format does not affect electrical or mechanical compatibility. The 1-770006-0 is specified with Cut Tape (CT) packaging, while 770006-4 and 770249-4 do not have packaging specifications provided. Packaging selection is determined by assembly process requirements and inventory management, not by connector functionality.

Q: Are there any wire gauge limitations when substituting these parts?

A: No. All three parts support the identical wire gauge range of 14-20 AWG. Substitution does not alter wire gauge compatibility.

Q: What does MSL 1 (Unlimited) mean for these socket contacts?

A: Moisture Sensitivity Level 1 indicates the lowest moisture sensitivity classification. All three parts carry MSL 1 (Unlimited), meaning they have unlimited shelf life and do not require special moisture control during storage or handling.

Q: Should I prioritize 1-770006-0 over 770249-4 for new designs?

A: Yes. The 1-770006-0 is the recommended choice for new designs because it carries active product status, ensuring long-term availability and support. It also meets ROHS3 compliance requirements. The 770249-4 is obsolete and should be reserved for legacy system maintenance only.
