TE Connectivity 1674012-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1674012-1 is a 16-position rectangular connector receptacle housing from the Multi-Lock series. This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing design and maintenance applications. The housing is designed for free-hanging in-line mounting with crimp contact termination and latch holder fastening. As an obsolete product, equivalent alternatives from active manufacturers are required to maintain supply chain continuity and support legacy system repairs.

Engineering Selection Recommendations

For Direct Receptacle Housing Replacement:

The Molex 0430251600 (Micro-Fit 3.0 series) is the primary substitute for the TE Connectivity 1674012-1. This part maintains receptacle connector type, 16-position configuration, 2-row layout, free-hanging in-line mounting, crimp termination, and latch lock fastening. The part is active in production, ROHS3 compliant, and carries MSL 1 rating. Inventory availability is highest among all substitutes at 10,810 pieces. Operating temperature range of -40°C to 105°C covers standard industrial applications.

The Molex 0334721601 (MX150 series) provides an alternative with extended operating temperature to 150°C, suitable for elevated-temperature environments. This part includes sealed features and maintains all core substitution parameters.

The Molex 0022552162 (SL 70450 series) offers compatibility with 0.100" (2.54mm) pitch spacing and includes polarizing key features. This part is suitable for applications requiring standard pitch spacing.

The JAE Electronics MX34016SF1 provides a compact alternative with 0.087" (2.20mm) pitch spacing for space-constrained applications while maintaining all core electrical and mechanical parameters.

For Mating Connector Pair Assembly:

The Hirose DF1B-16DEP-2.5RC and DF1BA-16DEP-2.5RC provide plug housing complements with 16 positions, 2 rows, and crimp termination. These parts are suitable for applications requiring complete connector pair assembly. The DF1B-16DEP-2.5RC supports free-hanging in-line mounting, while the DF1BA-16DEP-2.5RC provides panel mount snap-in capability.

The JAE Electronics IL-AG5-16P-D3C1 offers plug housing configuration with 0.098" (2.50mm) pitch and crimp termination for complementary assembly.

Compliance and Regulatory Status:

All recommended substitute parts maintain ROHS3 compliance and MSL 1 (unlimited) moisture sensitivity rating, ensuring regulatory alignment with the original component. REACH status is unaffected for all active Molex and JAE Electronics alternatives.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0430251600 directly replace the TE Connectivity 1674012-1 in existing assemblies?

A: The Molex 0430251600 maintains the same connector type (receptacle), position count (16), row configuration (2), mounting style (free-hanging in-line), and termination method (crimp). Mechanical fit compatibility depends on the specific PCB or cable assembly design. Physical dimensions and contact spacing should be verified against the original design specifications.

Q: What is the difference between the Molex receptacle substitutes in terms of pitch spacing?

A: The three Molex receptacle options differ in pitch spacing: 0022552162 uses 0.100" (2.54mm), 0430251600 uses 0.118" (3.00mm), and 0334721601 uses 0.138" (3.50mm). Pitch spacing determines the physical distance between contact positions and affects PCB layout compatibility. Selection depends on the original assembly's contact spacing requirements.

Q: Why are Hirose and JAE Electronics plug housings listed as substitutes for a receptacle housing?

A: Plug housings (DF1B-16DEP-2.5RC, IL-AG5-16P-D3C1) are included as complementary components for complete connector pair assembly. These parts are not direct replacements for the receptacle housing but serve as mating connectors in applications requiring both receptacle and plug components. They maintain the same 16-position, 2-row configuration and crimp termination.

Q: Are all substitute parts RoHS compliant?

A: All recommended substitute parts are ROHS3 compliant, matching the regulatory status of the original TE Connectivity 1674012-1. This ensures compatibility with RoHS-regulated applications and procurement requirements.

Q: What is the significance of the MSL 1 (Unlimited) rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements. All substitute parts carry this same rating, eliminating moisture-related handling and storage constraints during component procurement and assembly.

Q: Which substitute offers the highest inventory availability?

A: The Molex 0430251600 (Micro-Fit 3.0 series) provides the highest inventory availability at 10,810 pieces in stock. This availability level supports both immediate procurement needs and long-term supply chain planning.

Q: How do operating temperature ranges compare across substitutes?

A: Operating temperature ranges vary: Molex 0022552162 and 0430251600 support -40°C to 105°C; Molex 0334721601 extends to -40°C to 150°C; Hirose DF1B series supports -35°C to 85°C; JAE Electronics parts support -40°C to 85°C. Selection depends on the application's thermal environment requirements.

Q: What is the difference between Latch Holder and Latch Lock fastening types?

A: Both fastening types provide mechanical retention of the connector housing. Latch Holder and Latch Lock represent different mechanical locking mechanisms. The specific fastening type affects mating and unmating procedures. Compatibility with existing mating connectors should be verified during substitution.

Q: Can the JAE Electronics MX34016SF1 be used in applications requiring standard pitch spacing?

A: The MX34016SF1 uses 0.087" (2.20mm) pitch spacing, which is smaller than standard 0.100" spacing. This compact pitch is suitable for space-constrained applications but requires PCB layouts designed for this specific spacing. It is not interchangeable with standard-pitch designs.

Q: What packaging formats are available for these substitutes?

A: Substitute parts are available in Bulk packaging (Molex 0022552162, 0334721601, 0430251600; Hirose DF1B series; JAE Electronics IL-AG5-16P-D3C1) and Tray packaging (JAE Electronics MX34016SF1). Packaging selection affects handling, storage, and assembly processes.
