Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Cinch 12-140 is determined by the following critical parameters that must remain constant or compatible:

Fixed Parameters (No Variation Allowed):

• Number of circuits: 12
• Pitch spacing: 0.375" (9.53mm)
• Number of rows: 2
• Terminal block type: Barrier block
• Top termination method: Screws
• Bottom termination: Closed
• Barrier configuration: 2 Wall (Dual)
• Mounting type: Chassis, Panel
• Current rating: 15A

Flexible Parameters (Substitution Permitted Within Limits):

• Voltage rating: 250V minimum (300V acceptable for higher-rated designs)
• Wire gauge: 16 AWG (14-22 AWG range acceptable for broader compatibility)
• Insulation material: Phenol Formaldehyde or alternative thermoplastic materials (Polybutylene Terephthalate, Thermoplastic)
• Terminal screw finish: Nickel or Zinc with Clear Chromate
• Flammability rating: UL94 V-0 acceptable

The two Molex substitute parts (0387600112 and 0387700112) meet all fixed parameters while offering enhanced voltage ratings and broader wire gauge compatibility, making them suitable alternatives when the original part is unavailable or when design specifications permit the use of higher-rated components.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: Cinch 12-140

The Cinch 12-140 remains the preferred choice for new designs and ongoing production. The part is active in production status with adequate inventory (941 units in stock) and maintains full RoHS compliance and REACH unaffected status. This part is suitable for applications requiring 250V operation with 16 AWG wire gauge specifications.

Secondary Selection: Molex 0387700112

The Molex 0387700112 is the recommended substitute when the Cinch 12-140 is unavailable. This part maintains active production status and offers enhanced specifications including 300V voltage rating and 14-22 AWG wire gauge flexibility. The PBT insulation material with UL94 V-0 flammability rating provides improved thermal and flame characteristics compared to phenolic materials. ROHS3 compliance and REACH unaffected status ensure regulatory alignment. Inventory availability is strong at 1,388 units in stock.

Tertiary Selection: Molex 0387600112

The Molex 0387600112 is an alternative substitute with equivalent electrical and mechanical specifications to the 0387700112. However, this part carries Last Time Buy status, indicating discontinued production. Selection of this part should be limited to applications where existing inventory is available and long-term supply is not required. The thermoplastic insulation material differs from both the primary part and the secondary substitute.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0387700112 be used as a direct replacement for the Cinch 12-140?

A: Yes. Both parts maintain identical circuit count (12), pitch spacing (0.375"), row configuration (2), current rating (15A), and termination methods. The Molex part offers higher voltage rating (300V vs. 250V) and broader wire gauge compatibility (14-22 AWG vs. 16 AWG), making it electrically and mechanically compatible for applications designed around the Cinch specifications.

Q: What is the difference between the two Molex substitute parts?

A: The primary difference is insulation material composition and production status. The 0387700112 uses Polybutylene Terephthalate (PBT) and maintains active production status. The 0387600112 uses thermoplastic material and is designated Last Time Buy, indicating end-of-life production. Both parts share identical electrical ratings and mechanical dimensions.

Q: Are there any compatibility concerns with wire gauge differences?

A: The Cinch 12-140 specifies 16 AWG wire gauge, while the Molex substitutes accept 14-22 AWG range. This broader range in the Molex parts does not create compatibility issues for 16 AWG applications, as 16 AWG falls within the acceptable range. Applications using wire gauges outside the 16 AWG specification should verify that the substitute part's wire gauge range accommodates the intended conductor size.

Q: What is the significance of the voltage rating difference?

A: The Cinch 12-140 is rated for 250V operation, while both Molex substitutes are rated for 300V. The higher voltage rating in the Molex parts indicates enhanced dielectric strength and insulation capability. For applications operating at or below 250V, either part is suitable. Applications requiring operation above 250V must use the Molex substitutes.

Q: How do the insulation materials affect part selection?

A: The Cinch 12-140 uses Phenol Formaldehyde (phenolic) insulation, while the Molex 0387700112 uses PBT with UL94 V-0 flammability rating. PBT offers superior thermal stability and flame resistance. Selection between materials depends on application temperature requirements and flammability specifications. Both materials are suitable for the stated operating temperature range when used within their respective ratings.

Q: What does Last Time Buy status mean for the Molex 0387600112?

A: Last Time Buy status indicates that Molex has discontinued production of this part. Existing inventory may be available from distributors, but no new production runs are planned. This part should be selected only when immediate availability from existing stock is confirmed and long-term supply is not required for ongoing production.

Q: Are all three parts RoHS and REACH compliant?

A: The Cinch 12-140 is RoHS Compliant and REACH Unaffected. Both Molex substitutes are ROHS3 Compliant and REACH Unaffected. All three parts meet current regulatory requirements for hazardous substance restrictions and chemical safety.
