Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector headers is determined by matching the following critical parameters:

Mandatory Matching Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (12)
• Pitch - mating (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Contact length - mating (0.230" / 5.84mm)
• Contact length - post (0.130" / 3.30mm)
• Insulation height (0.535" / 13.60mm)
• Current rating (3A)
• Operating temperature range (-65°C ~ 105°C)
• Contact material (Brass)
• Contact finish - mating (Gold)
• Insulation material (Thermoplastic)
• Flammability rating (UL94 V-0)

Allowable Variation Parameters:

• Contact finish thickness - mating (15.0µin to 30.0µin)
• Contact finish - post (Tin-Lead or Tin)
• Overall contact length (minor variations within tolerance)
• Voltage rating (267V or unspecified)
• RoHS compliance status
• REACH compliance status

The substitute parts 6-104362-1 and 6-103908-1 satisfy all mandatory matching parameters and fall within allowable variation ranges for secondary characteristics.

Parameter Comparison

Engineering Selection Recommendations

1-103670-1 (Primary Part)

The 1-103670-1 is the original specification part with active product status. This part features Tin-Lead post finish and is not subject to RoHS compliance requirements. Selection is appropriate for applications where legacy post finish specifications are required or where RoHS compliance is not mandated.

6-104362-1 (Direct Substitute)

The 6-104362-1 is a direct functional equivalent with identical mating and post contact lengths. This part is ROHS3 compliant and features Tin post finish instead of Tin-Lead. The contact finish thickness on the mating surface remains at 15.0µin (0.38µm), matching the original specification. Selection is appropriate for applications requiring RoHS3 compliance or where Tin post finish is acceptable. Inventory availability is higher at 3066 units.

6-103908-1 (Functional Equivalent)

The 6-103908-1 is a functional equivalent with RoHS compliance status. This part features an increased mating contact finish thickness of 30.0µin (0.76µm) compared to the original 15.0µin specification, providing enhanced contact durability. The Tin post finish is compatible with standard soldering processes. Voltage rating is not specified for this part. Selection is appropriate for applications requiring RoHS compliance and where increased mating contact finish thickness provides design benefit. Inventory availability is highest at 4610 units.

All three parts share identical mechanical dimensions, electrical ratings, operating temperature ranges, and application suitability. Selection between these parts is determined by compliance requirements, post finish specifications, and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can 6-104362-1 be used as a direct replacement for 1-103670-1?

A: Yes. The 6-104362-1 is a direct functional equivalent. Both parts share identical connector type, position count, pitch, mounting configuration, contact lengths, insulation height, current rating, and operating temperature range. The primary difference is the post finish material (Tin versus Tin-Lead) and RoHS3 compliance status of the 6-104362-1. Mechanical and electrical compatibility is complete.

Q: What is the difference between the contact finish specifications on these parts?

A: The 1-103670-1 and 6-104362-1 both feature 15.0µin (0.38µm) gold plating on the mating contact surface. The 6-103908-1 features 30.0µin (0.76µm) gold plating on the mating contact surface, providing increased thickness. All three parts feature 100.0µin (2.54µm) finish on the post. The increased mating contact finish thickness on the 6-103908-1 does not affect mechanical or electrical compatibility.

Q: Are these parts suitable for automotive applications?

A: Yes. All three parts are rated for automotive applications and share identical operating temperature ranges of -65°C to 105°C. All parts meet UL94 V-0 flammability requirements and are suitable for automotive, general purpose, medical, and telecommunications applications.

Q: What is the difference between Tin-Lead and Tin post finish?

A: The 1-103670-1 features Tin-Lead post finish, while 6-104362-1 and 6-103908-1 feature Tin post finish. Both finishes are compatible with standard soldering processes. Tin post finish is associated with RoHS compliance, while Tin-Lead post finish is not subject to RoHS restrictions. Selection depends on compliance requirements and soldering process specifications.

Q: Can these parts be mixed in the same assembly?

A: Yes. All three parts are mechanically and electrically compatible. They share identical connector type, position count, pitch, mounting type, contact lengths, and electrical ratings. Mixing parts in the same assembly does not create compatibility issues, though design documentation should reflect the specific part numbers used.

Q: What is the significance of the RoHS compliance status differences?

A: The 1-103670-1 is not subject to RoHS compliance. The 6-104362-1 is ROHS3 compliant. The 6-103908-1 is RoHS compliant. Selection depends on end-use application requirements and regional regulatory mandates. For applications subject to RoHS restrictions, either 6-104362-1 or 6-103908-1 is required.

Q: Are there any differences in the overall contact length between these parts?

A: The 1-103670-1 does not specify overall contact length. The 6-104362-1 specifies 0.550" (13.97mm) overall contact length. The 6-103908-1 specifies 0.545" (13.84mm) overall contact length. These minor variations fall within normal manufacturing tolerances and do not affect mechanical or electrical compatibility.

Q: Which part should be selected for new designs?

A: Selection depends on specific design requirements. For RoHS-compliant applications, 6-104362-1 or 6-103908-1 are appropriate. For applications requiring increased mating contact durability, 6-103908-1 with 30.0µin gold plating is suitable. For applications without RoHS requirements and where legacy specifications are maintained, 1-103670-1 is appropriate. All parts are active in production with adequate inventory availability.
