Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 4-140 are qualified based on the following critical parameters that determine functional equivalence:

Mandatory Matching Parameters:

• Number of Circuits: 4
• Pitch: 0.375" (9.53mm)
• Current Rating: 15A
• Terminal Block Type: Barrier Block
• Top Termination: Screws
• Barrier Type: 2 Wall (Dual)
• Mounting Type: Chassis, Panel

Allowable Variations:

• Voltage Rating: Substitute parts rated at 300V exceed the 250V requirement and remain compatible
• Wire Gauge: Substitute parts accepting 14-22 AWG accommodate the 16 AWG specification
• Insulation Material: Thermoplastic and Polybutylene Terephthalate (PBT) provide equivalent electrical performance to Phenol Formaldehyde
• Terminal Screw Finish: Zinc with Clear Chromate provides equivalent corrosion protection to Nickel finish
• Flammability Rating: UL94 V-0 certification on substitute parts exceeds the unspecified rating of the main part

The two identified substitute parts (Molex 0387600104 and 0387700104) maintain all mandatory parameters while offering enhanced specifications in voltage rating and wire gauge flexibility.

Parameter Comparison

Engineering Selection Recommendations

Cinch 4-140 Primary Selection: The Cinch 4-140 remains the specified component when original design parameters are required. This part is active in production with adequate inventory (1368 units) and carries RoHS compliance certification.

Molex 0387700104 Preferred Substitute: The Molex 0387700104 is the primary substitute option. This part exceeds all mandatory electrical parameters, provides enhanced voltage rating (300V vs. 250V), accepts expanded wire gauge range (14-22 AWG vs. 16 AWG), and carries ROHS3 compliance with UL94 V-0 flammability certification. Inventory availability is superior (13848 units). The polybutylene terephthalate (PBT) insulation material provides enhanced mechanical and thermal properties compared to phenolic materials.

Molex 0387600104 Secondary Substitute: The Molex 0387600104 serves as an alternative substitute with identical electrical specifications to the 0387700104. The thermoplastic insulation material differs from both the primary part and the preferred substitute. This part carries ROHS3 compliance and UL94 V-0 certification with adequate inventory (2178 units).

Compliance Considerations: All parts maintain EAR99 export classification and 8536.90.4000 HTSUS coding. Substitute parts carry ROHS3 compliance, which supersedes the RoHS compliance of the primary part. All parts are REACH unaffected and carry MSL Level 1 (unlimited moisture sensitivity).

Frequently Asked Questions (FAQ)

Q: Can Molex 0387700104 directly replace Cinch 4-140 in existing designs?

A: Yes. The Molex 0387700104 maintains all mandatory functional parameters: 4 circuits, 0.375" pitch, 15A current rating, dual-wall barrier configuration, screw termination, and chassis/panel mounting capability. The higher voltage rating (300V) and expanded wire gauge acceptance (14-22 AWG) provide enhanced design margin without requiring circuit modifications.

Q: What is the difference between Molex 0387700104 and Molex 0387600104?

A: Both parts are electrically and mechanically equivalent substitutes for the Cinch 4-140. The primary difference is insulation material: 0387700104 uses polybutylene terephthalate (PBT) while 0387600104 uses thermoplastic. Both materials meet UL94 V-0 flammability requirements. Material selection depends on specific application thermal and mechanical requirements.

Q: Are the terminal screw finishes interchangeable?

A: The Cinch 4-140 features nickel-plated steel screws, while Molex substitutes feature zinc with clear chromate finish. Both finishes provide corrosion protection suitable for standard industrial environments. Specific application requirements for corrosion resistance in harsh environments should be evaluated independently.

Q: What wire gauges are compatible with each part?

A: The Cinch 4-140 is specified for 16 AWG wire. Molex substitutes accept 14-22 AWG wire, providing flexibility for applications requiring larger or smaller conductor sizes. The 16 AWG specification of the primary part falls within the acceptable range of both substitutes.

Q: Do the substitute parts carry the same regulatory certifications?

A: The Cinch 4-140 carries RoHS compliance. Molex substitutes carry ROHS3 compliance, which represents an enhanced regulatory standard. All parts are REACH unaffected and carry MSL Level 1 rating. Both substitute parts carry UL94 V-0 flammability certification, while the primary part does not specify a flammability rating.

Q: What is the inventory status for each part?

A: Cinch 4-140: 1368 units in stock. Molex 0387700104: 13848 units in stock. Molex 0387600104: 2178 units in stock. The Molex 0387700104 offers the highest inventory availability.

Q: Are there any operating temperature differences?

A: The Cinch 4-140 specifies operating temperature range of -55°F to 300°F. The Molex substitutes do not provide explicit operating temperature specifications in the available data. Applications requiring confirmed temperature performance should reference detailed manufacturer datasheets.
