Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1376600-4 are identified based on strict parametric equivalence within the CI 2 rectangular connector series. The substitution criteria are established by the following key parameters that must remain constant across all equivalent parts:

• Connector Type: Plug
• Contact Type: Female Socket
• Number of Positions: 47
• Number of Rows: 3
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Insulation Material: Polybutylene Terephthalate (PBT)
• Operating Temperature Range: -30°C ~ 105°C
• Features: Slide Cam
• Color: Black
• Series: CI 2
• RoHS Compliance: RoHS Compliant
• MSL Rating: 1 (Unlimited)

Parts meeting all these parameters are classified as parametric equivalents and are suitable for direct substitution in applications designed for the 1376600-4.

Parameter Comparison

Engineering Selection Recommendations

The 1376600-4 is classified as Last Time Buy, indicating that production has been discontinued. For new designs or long-term procurement requirements, selection of an Active product status part is recommended to ensure ongoing availability and supply chain stability.

Primary Substitute: 1376600-5

The 1376600-5 is the preferred substitute for the 1376600-4. Both parts are parametrically equivalent across all electrical and mechanical specifications. The 1376600-5 maintains Active product status, ensuring continued availability and manufacturing support. Inventory levels for the 1376600-5 (1130 pieces) exceed those of the main part, providing procurement flexibility.

Secondary Substitute: 1376600-3

The 1376600-3 is an alternative substitute with identical parametric specifications. This part also maintains Active product status. Inventory availability (640 pieces) is lower than the 1376600-5 but remains suitable for component selection.

Both substitute parts are RoHS Compliant and carry MSL Rating 1 (Unlimited), matching the compliance profile of the original part. No design modifications are required when substituting either equivalent part in existing applications.

Frequently Asked Questions (FAQ)

Q: Can the 1376600-3 or 1376600-5 be used as direct replacements for the 1376600-4?

A: Yes. Both the 1376600-3 and 1376600-5 are parametric equivalents of the 1376600-4. All electrical and mechanical parameters are identical, including connector type, contact configuration, position count, mounting method, termination type, insulation material, and operating temperature range. Direct substitution is supported without design modification.

Q: What is the difference between the 1376600-4, 1376600-3, and 1376600-5?

A: The three parts are parametrically identical. The only differences are the product status designation and current inventory levels. The 1376600-4 is Last Time Buy (discontinued production), while the 1376600-3 and 1376600-5 maintain Active status with ongoing manufacturing support.

Q: Why is the 1376600-4 designated as Last Time Buy?

A: Last Time Buy designation indicates that the manufacturer has discontinued production of this part number. Existing inventory remains available, but no future production runs are planned. This status necessitates identification of equivalent alternatives for long-term supply chain planning.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. The substitute parts maintain identical specifications for all parameters that determine mechanical and electrical compatibility: connector type, contact type, position count, row configuration, mounting type, termination method, and insulation material.

Q: What is the significance of the CI 2 series designation?

A: The CI 2 series is the product family classification for these rectangular connectors. All three parts belong to the same series, ensuring design compatibility and interchangeability within applications designed for CI 2 series connectors.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both the 1376600-3 and 1376600-5 are RoHS Compliant, matching the compliance status of the 1376600-4. All three parts meet RoHS requirements for restricted substance limitations.

Q: What does MSL Rating 1 (Unlimited) indicate?

A: MSL Rating 1 (Unlimited) indicates that the connector housing has minimal moisture sensitivity and does not require special moisture control during storage, handling, or assembly. This rating applies to all three equivalent parts.

Q: Which substitute part should be selected for new procurement?

A: The 1376600-5 is recommended for new procurement due to its Active product status and higher inventory availability (1130 pieces). The 1376600-3 is an acceptable alternative with identical specifications and Active status, though with lower current inventory levels (640 pieces).
