Engineering Selection Recommendations
All substitute parts listed maintain functional equivalence with the 176274-4 based on critical connector interface parameters: 6-position configuration, 0.156" pitch, 2-row layout with 0.181" row spacing, female socket contact type, crimp termination, and latch lock fastening.
Universal Power Series (176274 Base Number):
- 176274-4 (Yellow): ROHS3 Compliant, -30°C ~ 105°C operating range
- 176274-6 (Blue): ROHS3 Compliant, -30°C ~ 105°C operating range
- 176274-2 (Red): RoHS Compliant, -30°C ~ 105°C operating range
These three parts share identical electrical and mechanical specifications with only color differentiation. All maintain the full -30°C ~ 105°C operating temperature range and ROHS3 or RoHS compliance.
Power Double Lock Series (177901 and 368576 Base Numbers):
- 177901-1 (Natural): RoHS Compliant, operating temperature not specified
- 177901-6 (Blue): RoHS Compliant, operating temperature not specified
- 3-177901-6 (Blue): RoHS Compliant, operating temperature not specified, insulation material not specified
- 368576-1 (Natural): RoHS Compliant, -30°C ~ 65°C operating range
These parts maintain identical connector interface specifications. Operating temperature specifications differ: 368576-1 specifies -30°C ~ 65°C, while 177901 series does not specify operating temperature. Selection between Universal Power and Power Double Lock series depends on application requirements for operating temperature range and series-specific design features.
All parts are active products from TE Connectivity AMP Connectors with MSL rating of 1 (Unlimited) and are suitable for direct substitution based on connector interface compatibility.
Frequently Asked Questions (FAQ)
Q: What determines if a part can substitute for the 176274-4?
A: Substitution is determined by equivalence in the following parameters: 6-position configuration, 0.156" (3.96mm) pitch, 2-row layout, 0.181" (4.60mm) row spacing, plug connector type, female socket contact type, free hanging in-line mounting, crimp termination, and latch lock fastening. Color and series designation do not affect substitution eligibility.
Q: Can I use 176274-2 (Red) instead of 176274-4 (Yellow)?
A: Yes. Both parts are from the Universal Power series with identical electrical and mechanical specifications. The only difference is housing color. Both maintain -30°C ~ 105°C operating temperature and ROHS3 or RoHS compliance. Color selection is application-dependent and does not affect connector function.
Q: What is the difference between Universal Power series (176274) and Power Double Lock series (177901, 368576)?
A: Both series maintain identical connector interface specifications for the 6-position, 3.96mm pitch configuration. The series designation indicates different product lines within TE Connectivity's connector portfolio. Universal Power series parts specify -30°C ~ 105°C operating temperature. Power Double Lock series parts either do not specify operating temperature (177901 series) or specify -30°C ~ 65°C (368576-1). Selection depends on application operating temperature requirements.
Q: Is 3-177901-6 equivalent to 177901-6?
A: Both parts share identical connector interface specifications: 6-position, 0.156" pitch, 2-row configuration, female socket contacts, crimp termination, and latch lock fastening. The primary difference is that 3-177901-6 does not specify insulation material or operating temperature, while 177901-6 specifies Polyamide (PA66), Nylon 6/6 insulation material and does not specify operating temperature. Both are RoHS compliant and active products.
Q: Can I use 368576-1 in an application requiring -30°C ~ 105°C operation?
A: No. The 368576-1 specifies an operating temperature range of -30°C ~ 65°C, which does not meet the full -30°C ~ 105°C requirement. For applications requiring the full -30°C ~ 105°C operating range, use 176274-4, 176274-6, or 176274-2 from the Universal Power series.
Q: Are all substitute parts in stock?
A: Inventory status is provided for reference. 176274-4 has 782 units in stock. Substitute parts have varying inventory levels: 176274-6 (799 units), 176274-2 (1063 units), 177901-1 (1204 units), 177901-6 (2427 units), 3-177901-6 (782 units), and 368576-1 (3910 units). Inventory levels are subject to change and should be verified at time of procurement.
Q: What does MSL 1 (Unlimited) mean?
A: Moisture Sensitivity Level 1 (Unlimited) indicates that the component has no moisture sensitivity restrictions. These parts do not require special moisture control handling during storage, transportation, or assembly, and have unlimited shelf life under normal conditions.
Q: Are all substitute parts ROHS compliant?
A: Yes. All listed substitute parts are either ROHS3 Compliant (176274-4, 176274-6) or RoHS Compliant (176274-2, 177901-1, 177901-6, 3-177901-6, 368576-1). Both compliance levels meet regulatory requirements for restricted substances.
