Key Parameters

Substitute Part Grouping Explanation

Substitution between the main part 794071-1 and the identified substitute part 1-794071-0 is based on matching the following critical parameters:

Electrical Compatibility Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (22)
• Number of rows (2)
• Pitch spacing (0.163" / 4.14mm)
• Row spacing (0.163" / 4.14mm)
• Voltage rating (600VAC)
• Operating temperature range (-20°C ~ 85°C)

Mechanical Compatibility Parameters:

• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening type (Locking Ramp)
• Insulation material (Polyamide/Nylon)
• Insulation height (0.531" / 13.50mm)
• Contact material (Brass)
• Contact post length (0.175" / 4.45mm)
• Contact finish thickness (150.0µin / 3.81µm)

Functional Equivalence: Both parts belong to the Mini-Universal MATE-N-LOK series and maintain identical board-to-cable/wire interface specifications. The substitute part operates within the same electrical and thermal parameters, ensuring functional interchangeability in circuit board applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The 794071-1 and 1-794071-0 are functionally equivalent rectangular connector headers with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory compliance requirements and product status.

RoHS Compliance Consideration:

The substitute part 1-794071-0 carries ROHS3 compliance certification, while the main part 794071-1 is RoHS non-compliant. For applications subject to RoHS directives or customer specifications requiring RoHS compliance, the 1-794071-0 substitute is the appropriate selection.

Contact Finish Specification:

The main part 794071-1 features Tin-Lead contact finish on both mating and post surfaces. The substitute part 1-794071-0 features Tin contact finish. Both maintain identical contact finish thickness (150.0µin / 3.81µm). The contact finish difference reflects the RoHS compliance transition, with Tin finish replacing Tin-Lead in the compliant variant.

Inventory and Availability:

The main part 794071-1 has 860 units in stock. The substitute part 1-794071-0 has 751 units in stock. Both parts are active in production status.

Packaging Consideration:

The main part 794071-1 packaging specification is not provided. The substitute part 1-794071-0 is supplied in Bulk packaging.

Electrical and Thermal Performance:

Both parts operate identically within the 600VAC voltage rating and -20°C to 85°C operating temperature range. No performance differentiation exists between the parts for standard electrical applications.

Frequently Asked Questions (FAQ)

Q: Are the 794071-1 and 1-794071-0 directly interchangeable in circuit board designs?

A: Yes. Both parts maintain identical connector type, contact configuration, pitch spacing, mounting method, and electrical ratings. Direct substitution is possible without circuit board redesign. The primary difference is RoHS compliance status and contact finish composition.

Q: What is the significance of the contact finish difference between Tin-Lead and Tin?

A: The contact finish difference reflects regulatory compliance evolution. The 794071-1 uses Tin-Lead finish (RoHS non-compliant), while the 1-794071-0 uses Tin finish (ROHS3 compliant). Both finishes maintain the same thickness specification (150.0µin / 3.81µm) and provide equivalent electrical contact performance. The Tin finish in the substitute part eliminates lead content per RoHS3 requirements.

Q: Which part should be selected for new designs?

A: For new designs subject to RoHS directives or customer RoHS requirements, select the 1-794071-0 substitute part. For applications without RoHS compliance requirements, either part is acceptable based on availability and inventory status.

Q: Do both parts support the same current and voltage specifications?

A: Yes. Both parts are rated for 600VAC operation. Current rating varies by wire gauge for both parts, as current capacity is determined by the mating wire specification rather than the connector header itself.

Q: Are there any thermal performance differences between the parts?

A: No. Both parts operate within the identical temperature range of -20°C to 85°C. Thermal performance is equivalent.

Q: What is the moisture sensitivity level for both parts?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Can the 794071-1 be used in applications requiring RoHS compliance?

A: No. The 794071-1 is RoHS non-compliant due to its Tin-Lead contact finish. For RoHS-compliant applications, the 1-794071-0 substitute must be used.

Q: Are the shrouding and board lock features identical on both parts?

A: Yes. Both parts feature identical 4-wall shrouding and board lock functionality, ensuring equivalent mechanical retention and connector alignment in board-to-cable/wire applications.
