Key Parameters

Substitute Part Grouping Explanation

Substitution between the main part 770972-1 and the identified substitute 1-770972-0 is based on strict equivalence of the following critical parameters:

Electrical Compatibility Parameters:

• Contact type (Male Pin)
• Number of positions (12)
• Number of rows (2)
• Pitch - mating (0.163" / 4.14mm)
• Row spacing - mating (0.163" / 4.14mm)
• Voltage rating (600VAC)
• Operating temperature range (-20°C ~ 85°C)

Mechanical Compatibility Parameters:

• Connector type (Header)
• Mounting type (Through Hole, Right Angle)
• Shrouding (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening type (Locking Ramp)
• Insulation material (Polyamide PA, Nylon)
• Material flammability rating (UL94 V-0)

Packaging and Compliance Variations:

• Packaging format (Bulk vs. standard)
• Contact finish material (Tin-Lead vs. Tin)
• RoHS compliance status
• REACH status

The substitute part maintains full electrical and mechanical interchangeability while differing in packaging configuration and material finish specifications.

Parameter Comparison

Engineering Selection Recommendations

770972-1 Selection Criteria:

• Applications requiring Tin-Lead contact finish
• Projects with RoHS non-compliant material specifications
• Standard packaging requirements
• REACH Affected compliance documentation

1-770972-0 Selection Criteria:

• Applications requiring RoHS compliance
• Tin contact finish material specifications
• Bulk packaging requirements
• Projects with undefined REACH status tolerance

Both parts are active products with current production status and adequate inventory levels. The primary differentiators are contact finish material composition and regulatory compliance certifications. Selection between these parts depends on specific project compliance requirements and material finish specifications rather than electrical or mechanical performance, as all critical parameters remain identical.

Frequently Asked Questions (FAQ)

Q: Are 770972-1 and 1-770972-0 electrically interchangeable?

A: Yes. Both parts maintain identical electrical specifications including 12-position configuration, 0.163" (4.14mm) pitch, 600VAC voltage rating, and -20°C to 85°C operating temperature range. Contact finish material differences (Tin-Lead vs. Tin) do not affect electrical interchangeability.

Q: What is the primary difference between these two parts?

A: The main differences are contact finish material (Tin-Lead in 770972-1 versus Tin in 1-770972-0), RoHS compliance status (non-compliant versus compliant), and packaging format (standard versus bulk). All mechanical and electrical parameters are identical.

Q: Can I substitute 1-770972-0 for 770972-1 in my design?

A: Mechanical and electrical substitution is direct. However, regulatory compliance requirements must be evaluated. If your application requires RoHS compliance, 1-770972-0 is the appropriate selection. If Tin-Lead contact finish is specified, 770972-1 is required.

Q: What does the packaging difference mean?

A: 770972-1 is supplied in standard packaging, while 1-770972-0 is supplied in bulk packaging. This affects order quantities and handling but does not impact connector performance or compatibility.

Q: Are both parts currently available?

A: Yes. 770972-1 has 2178 pieces in inventory, and 1-770972-0 has 2200 pieces in inventory. Both are active products in current production.

Q: What is the significance of the contact finish difference?

A: Tin-Lead (770972-1) and Tin (1-770972-0) finishes provide equivalent electrical performance and corrosion resistance. The selection depends on regulatory requirements and material specifications for your application. Tin finish in 1-770972-0 supports RoHS compliance.

Q: Can these connectors be used interchangeably on the same PCB?

A: Yes. Both connectors have identical mechanical dimensions, mounting type (through-hole right-angle), shrouding configuration, and termination method. They are directly interchangeable at the PCB level.

Q: What is the REACH status difference?

A: 770972-1 is marked as REACH Affected, while 1-770972-0 is marked as Vendor Undefined. This distinction may affect regulatory documentation requirements depending on your application's geographic market and compliance obligations.
