Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 770873-2 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Voltage Rating: 600VAC
• Operating Temperature Range: -20°C ~ 105°C
• Contact Type: Male Pin
• Contact Material: Brass

Mechanical Compatibility Parameters:

• Number of Positions: 3
• Pitch - Mating: 0.163" (4.14mm)
• Mounting Type: Through Hole
• Shrouding: Shrouded - 4 Wall
• Insulation Material: Polyamide (PA), Nylon
• Insulation Height: 0.531" (13.50mm)
• Contact Shape: Circular
• Fastening Type: Locking Ramp
• Features: Board Lock

Termination Parameters:

• Termination Method: Solder
• Contact Length - Post: 0.175" (4.45mm)
• Contact Finish Thickness - Post: 150.0µin (3.81µm)

The substitute part 1-770873-1 maintains full equivalence across all critical electrical and mechanical parameters. Variations in post contact finish material (tin versus tin-lead) and regulatory compliance status do not affect functional interchangeability within the specified operating parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the 770873-2 and 1-770873-1 maintain active product status and are manufactured by TE Connectivity AMP Connectors within the Mini-Universal MATE-N-LOK series. The parts are electrically and mechanically equivalent across all critical operating parameters.

Selection Criteria Based on Compliance and Certification:

The 770873-2 carries a "Not applicable" RoHS status, while the 1-770873-1 is ROHS3 Compliant. For applications requiring RoHS3 compliance, the 1-770873-1 is the appropriate selection. Both parts maintain identical UL94 V-0 flammability ratings and equivalent electrical performance across the 600VAC voltage rating and -20°C to 105°C operating temperature range.

The 1-770873-1 offers significantly higher inventory availability (3372 units versus 730 units), making it suitable for applications where supply chain continuity is a consideration. The post contact finish variation (tin versus tin-lead) does not affect functional interchangeability within the specified solder termination process and operating environment.

Frequently Asked Questions (FAQ)

Q: Are the 770873-2 and 1-770873-1 electrically interchangeable?

A: Yes. Both connectors operate at 600VAC with identical operating temperature ranges (-20°C ~ 105°C), contact materials (brass), and contact configurations (3-position male pin headers with 0.163" pitch). Electrical performance is equivalent.

Q: What is the difference between tin-lead and tin post finishes?

A: The 770873-2 features tin-lead plated posts, while the 1-770873-1 features tin-plated posts. Both finishes are compatible with standard solder termination processes and provide equivalent contact reliability within the specified operating parameters. The tin finish on the 1-770873-1 aligns with RoHS3 compliance requirements.

Q: Can I use the 1-770873-1 as a direct replacement for the 770873-2?

A: Yes. The 1-770873-1 is a direct substitute. All mechanical dimensions, contact configurations, mounting specifications, and electrical ratings are identical. The parts are pin-compatible and functionally equivalent.

Q: Why does the 1-770873-1 have higher inventory availability?

A: The 1-770873-1 maintains 3372 units in stock compared to 730 units for the 770873-2. This reflects current supply chain positioning and demand patterns. Both parts remain active products.

Q: What is the significance of the RoHS3 compliance difference?

A: The 1-770873-1 is explicitly ROHS3 Compliant, while the 770873-2 carries "Not applicable" status. For applications subject to RoHS3 regulations or customer requirements, the 1-770873-1 is the appropriate selection. Both parts meet UL94 V-0 flammability standards.

Q: Are the shrouding and board lock features identical?

A: Yes. Both connectors feature identical 4-wall shrouding and board lock fastening mechanisms. Mechanical engagement and retention characteristics are equivalent.

Q: What is the pitch specification, and is it identical between both parts?

A: Both connectors maintain a mating pitch of 0.163" (4.14mm) with 3 positions in a single row. This specification is identical and ensures mechanical compatibility with corresponding receptacle connectors in the Mini-Universal MATE-N-LOK series.
