Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 2-794619-2 with the active equivalent 5-794619-2 is based on strict electrical and mechanical parameter equivalence. Both parts share identical specifications across all critical substitution criteria:

Key Parameters Determining Substitution Validity:

• Connector series designation (Micro MATE-N-LOK)
• Position count and row configuration (22 positions, 2 rows)
• Mating pitch and row spacing (0.118" / 3.00mm)
• Mounting orientation and type (Through Hole, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Contact type and material (Male Pin, Brass)
• Insulation material and color (Polyamide/Nylon, Black)
• Electrical ratings (250V, -40°C ~ 105°C)
• Fastening mechanism (Locking Ramp with Board Lock)
• Termination method (Solder)

The primary distinction between these parts is product status (obsolete versus active) and packaging format, with a secondary difference in post-contact finish composition.

Parameter Comparison

Engineering Selection Recommendations

The 5-794619-2 is the direct active equivalent for the obsolete 2-794619-2. Both parts maintain identical electrical and mechanical specifications, ensuring functional interchangeability in all applications. The substitute part offers the following advantages:

Product Status: The 5-794619-2 carries active product status with documented availability of 1474 pieces in stock, compared to the obsolete status of the original part.

Regulatory Compliance: The 5-794619-2 is ROHS3 compliant, whereas the original 2-794619-2 is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulations and environmental compliance requirements.

Contact Finish Specification: The substitute part features a Tin post-contact finish, compared to the Tin-Lead finish of the original part. Both maintain identical contact finish thickness (100.0µin / 2.54µm) and mating surface finish (Gold, 15.0µin / 0.38µm). This change aligns with lead-free manufacturing standards.

Packaging: The substitute is supplied in Tray packaging, providing standardized handling and storage compared to the unspecified packaging of the original part.

All other electrical, mechanical, and environmental specifications remain identical, confirming direct substitution capability without design modification or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can the 5-794619-2 be used as a direct replacement for the 2-794619-2 in existing designs?

A: Yes. The 5-794619-2 is electrically and mechanically identical to the 2-794619-2 across all critical parameters including connector type, position count, pitch, mounting configuration, and electrical ratings. Direct substitution is supported without design changes.

Q: What is the significance of the RoHS compliance difference between these parts?

A: The 5-794619-2 is ROHS3 compliant while the 2-794619-2 is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, the 5-794619-2 is the appropriate selection. The compliance difference reflects manufacturing process updates rather than functional changes.

Q: Does the change from Tin-Lead to Tin post-contact finish affect performance?

A: No. Both finishes maintain identical contact finish thickness (100.0µin / 2.54µm) and mating surface specifications (Gold, 15.0µin / 0.38µm). The Tin finish on the 5-794619-2 represents a lead-free alternative aligned with current manufacturing standards while maintaining electrical and mechanical performance.

Q: Are the mating and row spacing specifications identical between these parts?

A: Yes. Both parts feature 0.118" (3.00mm) mating pitch and 0.118" (3.00mm) row spacing. The 22-position, 2-row configuration is identical, ensuring mechanical compatibility with existing mating connectors and PCB layouts.

Q: What is the difference in packaging between these parts?

A: The 2-794619-2 packaging is not specified in available documentation. The 5-794619-2 is supplied in Tray packaging, which provides standardized handling, storage, and automated assembly compatibility.

Q: Are the operating temperature and voltage ratings the same?

A: Yes. Both parts operate across the identical temperature range of -40°C to 105°C and carry a 250V voltage rating. Environmental performance specifications are fully equivalent.

Q: Does the shrouding configuration remain unchanged?

A: Yes. Both parts feature Shrouded - 4 Wall configuration with Board Lock features. The mechanical protection and keying mechanisms are identical.

Q: What inventory status should be considered for procurement?

A: The 5-794619-2 is actively manufactured with 1474 pieces documented in stock. The 2-794619-2 is obsolete. For new production and ongoing support, the 5-794619-2 is the appropriate selection based on availability and active product status.
