Parameter Comparison

Engineering Selection Recommendations

Primary Selection (794939-1): The main part number 794939-1 is the recommended selection for new designs and applications. This part maintains Active product status with ROHS3 compliance certification and demonstrates adequate inventory availability at 1457 pieces.

Secondary Selection (172159-1): Part number 172159-1 serves as the direct functional equivalent to 794939-1, offering identical electrical and mechanical specifications with Natural color housing. This part maintains Active product status, ROHS3 compliance, and higher inventory availability at 2000 pieces. Selection of 172159-1 is appropriate when primary inventory is constrained.

Alternative Selection (1-172159-2): Part number 1-172159-2 provides equivalent functionality with Red color housing specification. This part maintains Active product status with RoHS compliance certification and the highest inventory availability at 46575 pieces. This part is suitable for applications requiring color-coded connector identification or when primary and secondary options are unavailable.

Obsolete Alternative (1-172159-5): Part number 1-172159-5 is classified as Obsolete product status with limited inventory at 707 pieces. This part maintains ROHS3 compliance and identical electrical specifications but is not recommended for new designs or long-term production applications due to discontinued status.

Frequently Asked Questions (FAQ)

Q: Can 172159-1 be used as a direct replacement for 794939-1?

A: Yes. Part number 172159-1 is a direct functional equivalent. Both parts share identical specifications for connector type, position count, pitch, mounting configuration, and operating temperature range. The primary difference is the base product number designation, with both maintaining equivalent electrical and mechanical performance.

Q: What is the difference between the Natural and Red color variants?

A: The color difference between 794939-1 (Natural) and 1-172159-2 (Red) is a housing aesthetic specification only. Both parts maintain identical electrical and mechanical characteristics, pitch, position count, and mounting specifications. Color selection is application-dependent for circuit board identification or system organization purposes.

Q: Why is 1-172159-5 listed as Obsolete?

A: Part number 1-172159-5 carries Obsolete product status designation from the manufacturer. While the part maintains identical electrical and mechanical specifications and ROHS3 compliance, it is no longer in active production. This part should not be selected for new designs or applications requiring long-term component availability.

Q: Are all substitute parts RoHS compliant?

A: All listed substitute parts maintain RoHS compliance. The main part 794939-1 and parts 1-172159-5 and 172159-1 carry ROHS3 certification. Part 1-172159-2 carries RoHS Compliant certification. Both compliance levels satisfy regulatory requirements for electronic component applications.

Q: What is the significance of the Moisture Sensitivity Level (MSL) rating?

A: All listed parts carry MSL rating of 1 (Unlimited), indicating unlimited shelf life without moisture exposure precautions. This specification applies uniformly across all substitute options and eliminates moisture sensitivity as a differentiation factor in part selection.

Q: Can these connectors be used interchangeably in existing assemblies?

A: Yes, all substitute parts maintain identical mechanical mounting specifications (Panel Mount, Snap-In) and pitch configuration (0.163" / 4.14mm). Interchangeability is confirmed for all listed alternatives within the same assembly design, provided color specification does not impose application constraints.

Q: What is the difference between PA and PA66 insulation material specifications?

A: The main part 794939-1 specifies Polyamide (PA) Nylon insulation, while substitute parts 1-172159-2, 1-172159-5, and 172159-1 specify Polyamide (PA66) Nylon 6/6 insulation. Both materials maintain identical operating temperature range (-20°C ~ 105°C) and electrical performance characteristics. Material composition differences do not affect functional substitution eligibility.

Q: Is inventory availability a factor in part selection?

A: Inventory availability is provided for reference purposes. Part 1-172159-2 demonstrates the highest inventory at 46575 pieces, while 1-172159-5 shows the lowest at 707 pieces. Inventory levels should be verified with current suppliers, as stock quantities are subject to change based on demand and procurement cycles.
