Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Cinch 8-140 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• Circuit Configuration: 8 circuits with 0.375" (9.53mm) nominal pitch spacing
• Electrical Performance: Minimum 15A current rating and 250V voltage rating
• Termination Method: Screw-based top termination with closed bottom configuration
• Barrier Construction: Dual-wall (2 Wall) barrier type for circuit isolation
• Mounting Interface: Chassis and panel mounting capability
• Physical Form Factor: 2-row configuration with flange feature and black color

The following parts meet these substitution criteria:

• Molex 0387600108 (Beau 38760 series): Meets all core parameters with expanded wire gauge range (14-22 AWG) and higher voltage rating (300V)
• Molex 0387700108 (Beau 38770 series): Meets all core parameters with expanded wire gauge range (14-22 AWG) and higher voltage rating (300V)
• TE Connectivity 1546306-8 (Buchanan series): Meets all core parameters with higher current rating (20A), expanded wire gauge range (12-22 AWG), and higher voltage rating (300V)

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with current manufacturing status and full RoHS3 compliance, ensuring regulatory alignment with modern procurement standards. Selection among these equivalents should be based on the following engineering considerations:

Molex 0387600108 and 0387700108: Both Molex Beau series parts provide direct electrical compatibility with the Cinch 8-140, offering expanded wire gauge accommodation (14-22 AWG versus 16 AWG) and elevated voltage rating (300V versus 250V). The primary distinction between these two Molex options lies in insulation material: thermoplastic versus PBT. Both maintain identical electrical ratings and mechanical form factors. These parts are suitable for applications requiring higher voltage margins or flexible wire gauge specifications.

TE Connectivity 1546306-8: The Buchanan series part provides the highest current rating (20A) and broadest wire gauge range (12-22 AWG), offering maximum electrical headroom for demanding applications. The pitch specification of 0.374" (9.50mm) represents a 0.01" (0.25mm) deviation from the nominal 0.375" (9.53mm) standard, which falls within typical mechanical tolerance ranges for barrier block connectors. This part is recommended for applications requiring enhanced current capacity or extended wire gauge flexibility.

All substitute parts maintain dual-wall barrier construction, screw termination, flange mounting features, and black color consistency with the original Cinch 8-140 specification.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0387600108 or 0387700108 be used as direct replacements for the Cinch 8-140?

A: Yes. Both Molex parts meet the core substitution criteria: 8-circuit configuration, 0.375" pitch, 15A current rating, 300V voltage rating (exceeding the 250V requirement), dual-wall barrier construction, screw termination, and identical mounting interfaces. The expanded wire gauge range (14-22 AWG) provides additional flexibility compared to the 16 AWG specification of the Cinch part.

Q: What is the significance of the pitch difference in the TE Connectivity 1546306-8 (0.374" versus 0.375")?

A: The 0.01" (0.25mm) pitch variation represents a 0.27% deviation from nominal spacing. This tolerance is within standard mechanical specifications for barrier block connectors and does not affect functional compatibility or circuit isolation. The part maintains the same 8-circuit, 2-row configuration and mounting interface as the Cinch 8-140.

Q: Are there differences in insulation material between the substitute parts?

A: Yes. The Cinch 8-140 uses Phenol Formaldehyde (Phenolic) insulation, while the Molex 0387600108 uses Thermoplastic and the Molex 0387700108 uses Polybutylene Terephthalate (PBT). All three materials are rated UL94 V-0 or equivalent for flammability performance. Material selection should be based on specific application requirements for temperature stability, chemical resistance, or mechanical properties.

Q: Which substitute part offers the highest electrical performance?

A: The TE Connectivity 1546306-8 provides the highest electrical ratings with 20A current capacity (versus 15A) and 300V voltage rating. It also accommodates the widest wire gauge range (12-22 AWG). This part is optimal for applications requiring maximum electrical headroom or flexibility in conductor sizing.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts are RoHS3 compliant. The original Cinch 8-140 is RoHS compliant. All parts are REACH unaffected and classified under ECCN EAR99 with identical HTSUS code 8536.90.4000.

Q: What inventory levels are available for each part?

A: Current stock levels are: Cinch 8-140 (993 units), Molex 0387600108 (1102 units), Molex 0387700108 (1778 units), and TE Connectivity 1546306-8 (7108 units). The TE Connectivity part offers the highest inventory availability.
