Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 13-140 is determined by the following critical parameters:

• Circuit Configuration: 13 circuits with 26 wire entries in 2-row arrangement
• Pitch Specification: 0.375" (9.53mm) center-to-center spacing
• Termination Method: Screw-based top termination with closed bottom configuration
• Barrier Construction: Dual-wall (2 Wall) barrier type
• Electrical Performance: Minimum 15A current rating and 250V voltage rating
• Mounting Interface: Chassis or panel mounting capability
• Connector Class: Barrier block terminal strip

The Molex 0387700113 satisfies all substitution criteria through matching circuit count, pitch, termination style, barrier configuration, and mounting compatibility. Electrical ratings exceed the original specification (300V vs. 250V), and wire gauge acceptance range (14-22 AWG) encompasses the original 16 AWG specification.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0387700113 is a direct functional substitute for the obsolete Cinch 13-140. Selection is based on the following engineering factors:

Electrical Compatibility: The substitute meets or exceeds all electrical requirements. The 300V rating provides margin above the original 250V specification, and the 15A current rating matches the original. Wire gauge acceptance (14-22 AWG) fully encompasses the original 16 AWG specification.

Physical Compatibility: Identical circuit count (13), pitch (0.375"), row configuration (2), and mounting interface (chassis/panel) ensure direct mechanical substitution without PCB or mounting redesign.

Termination Compatibility: Screw-based top termination and closed bottom configuration are identical, allowing existing wiring harnesses and termination procedures to remain unchanged.

Product Status: The Molex part is in active production with 1870 units in stock, ensuring long-term availability compared to the obsolete Cinch original.

Compliance: The original Cinch part is RoHS compliant. The Molex substitute carries UL94 V-0 flammability rating, indicating enhanced material performance in the polybutylene terephthalate (PBT) insulation versus the phenolic material of the original.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0387700113 be used as a direct replacement for the Cinch 13-140 without circuit board modifications?

A: Yes. The substitute maintains identical pitch (0.375"), circuit count (13), row configuration (2), and mounting interface. No PCB layout changes are required.

Q: What is the difference in insulation material between the original and substitute?

A: The Cinch 13-140 uses phenol formaldehyde (phenolic) insulation. The Molex 0387700113 uses polybutylene terephthalate (PBT) with UL94 V-0 flammability rating, indicating superior flame resistance.

Q: Does the higher voltage rating of the Molex part (300V vs. 250V) affect compatibility?

A: No. A higher voltage rating indicates the substitute can safely operate at the original specification voltage (250V) with additional margin. This is a favorable characteristic for substitution.

Q: Are there packaging differences between the original and substitute?

A: The Cinch 13-140 packaging is not specified in available data. The Molex 0387700113 is supplied in tray packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What wire gauges are compatible with the Molex substitute?

A: The Molex 0387700113 accepts 14-22 AWG wire. The original specification of 16 AWG falls within this range and is fully compatible.

Q: Is the Molex part RoHS compliant?

A: RoHS compliance status for the Molex 0387700113 is not specified in the provided data. The original Cinch 13-140 is RoHS compliant. Verify compliance requirements with your regulatory or procurement department.
