Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connectors in the Multi-Lock series is determined by the following critical parameters:

Primary Compatibility Criteria:

• Identical number of positions (16)
• Identical number of rows (2)
• Identical mating pitch (0.098" / 2.50mm)
• Identical mounting type (Through Hole, Right Angle)
• Identical shrouding configuration (Shrouded - 4 Wall)
• Identical termination method (Solder)
• Identical connector style (Board to Cable/Wire)
• Identical contact type (Tab)
• Identical contact shape (Rectangular)

Secondary Compatibility Parameters:

• Operating temperature range
• Row spacing tolerance
• Contact length specifications
• Insulation height
• Fastening mechanism type

The substitute part 174053-2 maintains all primary compatibility criteria with the main part 1123419-1. Variations exist in secondary parameters including row spacing, contact lengths, insulation height, fastening type, and operating temperature range. These variations require engineering evaluation for specific application contexts.

Parameter Comparison

Engineering Selection Recommendations

Part 1123419-1 Selection Criteria:

• Primary choice when operating temperature range of -40°C to 120°C is required
• Preferred when glass-filled PBT insulation material is specified
• Suitable for applications requiring latch holder fastening mechanism
• Appropriate when natural-colored insulation is required for identification or aesthetic purposes

Part 174053-2 Selection Criteria:

• Acceptable substitute when operating temperature range of -30°C to 105°C meets application requirements
• Suitable when standard PBT insulation (non-glass-filled) is acceptable
• Appropriate for applications compatible with locking ramp fastening mechanism
• Viable when black insulation color is acceptable or preferred
• Recommended when higher inventory availability is advantageous
• Compliant with ROHS3 certification requirements

Compliance Status: Both parts maintain active product status with TE Connectivity AMP Connectors. Both are RoHS compliant, MSL Level 1, and classified under identical ECCN and HTSUS codes. The substitute part 174053-2 carries ROHS3 compliance designation, representing a more recent regulatory compliance version.

Mechanical Compatibility Considerations: The substitute part exhibits dimensional variations in row spacing (0.31mm difference), contact post length (0.40mm difference), and insulation height (3.31mm difference). These variations require verification against specific printed circuit board layout, mating connector specifications, and mechanical clearance requirements in the target application.

Frequently Asked Questions (FAQ)

Q: Can part 174053-2 be used as a direct replacement for 1123419-1 in all applications?

A: Part 174053-2 maintains identical electrical and functional specifications for connector position count, pitch, mounting type, and termination method. However, dimensional variations in row spacing, contact post length, and insulation height require verification against specific application requirements, printed circuit board layouts, and mating connector specifications before substitution.

Q: What is the significance of the row spacing difference between these parts?

A: The row spacing variation of 0.31mm (5.51mm versus 5.20mm) affects the physical distance between connector rows. This difference impacts printed circuit board trace routing, component placement, and compatibility with mating connectors. Applications with tight layout constraints or specific mating connector requirements must account for this variation.

Q: Why does the operating temperature range differ between these parts?

A: Part 1123419-1 operates across -40°C to 120°C, while part 174053-2 operates across -30°C to 105°C. Applications requiring operation at temperatures below -30°C or above 105°C must use part 1123419-1. Applications operating within the -30°C to 105°C range can use either part.

Q: What is the difference between latch holder and locking ramp fastening types?

A: Both fastening mechanisms secure the connector to the mating interface. Latch holder (1123419-1) and locking ramp (174053-2) represent different mechanical engagement designs. The specific fastening type must be compatible with the mating connector design and application requirements.

Q: Does the glass-filled versus standard PBT insulation material affect substitution?

A: Part 1123419-1 uses glass-filled PBT insulation, while part 174053-2 uses standard PBT insulation. Glass-filled material provides enhanced mechanical strength and dimensional stability. Applications requiring specific material properties or mechanical performance specifications must verify compatibility with the substitute material composition.

Q: What is the significance of the insulation height difference?

A: The insulation height variation of 3.31mm (13.40mm versus 16.71mm) affects the overall connector profile and clearance requirements in the application. Applications with height constraints or specific mechanical envelope requirements must verify that the substitute part dimensions are compatible with available space.

Q: Are both parts suitable for automotive applications?

A: Both parts are specified for automotive and general-purpose applications. Both maintain identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications. Specific automotive qualification requirements or OEM specifications must be verified independently for each application context.

Q: What is the difference in packaging between these parts?

A: Part 1123419-1 packaging is not specified in the available data. Part 174053-2 is supplied in tube packaging. Packaging differences may affect handling, storage, and assembly process integration. Verify packaging compatibility with receiving, storage, and assembly procedures.

Q: Why is inventory availability different between these parts?

A: Part 1123419-1 has 885 pieces in stock, while part 174053-2 has 8100 pieces in stock. Higher inventory availability for part 174053-2 may provide advantages for supply chain continuity and lead time reduction when substitution is technically acceptable.

Q: Are both parts RoHS compliant?

A: Both parts are RoHS compliant. Part 1123419-1 carries RoHS Compliant designation, while part 174053-2 carries ROHS3 Compliant designation. ROHS3 represents a more recent version of the RoHS compliance standard. Both parts meet current regulatory requirements for restricted substance elimination.
