Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 316874-4 is determined by strict equivalence across all specified electrical and mechanical parameters. The following parameters must match identically for a part to function as a direct substitute:

• Connector Type: Plug
• Contact Type: Female Socket
• Number of Positions: 25
• Number of Rows: 3
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Insulation Material: Polybutylene Terephthalate (PBT)
• Color: Black
• Features: Positions Molded Closed
• Series: CI 2

The 316874-1 meets all these criteria and qualifies as a parametric equivalent. Both parts share identical mechanical and electrical specifications within the CI 2 series, differing only in product lifecycle status and RoHS certification revision level.

Frequently Asked Questions (FAQ)

Q: Can the 316874-1 be used as a direct replacement for the 316874-4 in existing designs?

A: Yes. The 316874-1 is a parametric equivalent with identical connector type, contact configuration, position count, row arrangement, mounting method, termination type, insulation material, and color. No design changes are required for substitution.

Q: What is the significance of the Last Time Buy status on the 316874-4?

A: Last Time Buy status indicates that TE Connectivity has discontinued production of the 316874-4. This designation signals the final opportunity to purchase existing inventory before the part becomes unavailable. The 316874-1 remains in Active production status.

Q: Are there differences in RoHS compliance between these parts?

A: Both parts comply with RoHS regulations. The 316874-4 carries RoHS Compliant certification, while the 316874-1 carries ROHS3 Compliant certification. Both certifications confirm conformance to lead-free and restricted substance requirements.

Q: Do these parts require different contact specifications?

A: No. Both the 316874-4 and 316874-1 are housings designed for crimp termination with female socket contacts. Contact specifications remain identical between the two parts. Contacts are supplied separately and are not included with either housing.

Q: What is the moisture sensitivity level for these connector housings?

A: Both parts carry Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture control requirements. Standard storage conditions are suitable for these components.

Q: Are there any mechanical dimension differences between the 316874-4 and 316874-1?

A: No mechanical dimension parameters were provided in the specifications. Both parts share identical row count (3), position count (25), mounting type (free hanging in-line), and physical configuration within the CI 2 series.

Q: Can these housings be used interchangeably in the same connector assembly?

A: Yes. The 316874-1 provides complete mechanical and electrical interchangeability with the 316874-4. Both housings accommodate the same contact configuration and mounting requirements.
