Key Parameters

Substitute Part Grouping Explanation

Substitution between the TE Connectivity 104450-1 and 5-104450-1 is based on matching the following critical parameters:

Electrical Compatibility:

• Identical connector type (Header), contact type (Male Pin), and current rating (3A)
• Matching pitch specification (0.100" / 2.54mm)
• Identical operating temperature range (-65°C ~ 105°C)

Mechanical Compatibility:

• Same number of positions (2) and row configuration (1 row)
• Identical mounting type (Through Hole) and shrouding (Shrouded - 4 Wall)
• Matching contact dimensions and overall connector geometry
• Same termination options (Press-Fit, Solder)

Material and Construction:

• Identical contact material (Brass) and insulation material (Thermoplastic)
• Same flammability rating (UL94 V-0)
• Matching contact shape (Square) and fastening type (Latch Holder)

Variation Identified:

• Contact finish specification differs: 104450-1 uses Tin-Lead finish; 5-104450-1 uses Tin finish
• RoHS compliance status differs: 104450-1 is Not applicable; 5-104450-1 is RoHS Compliant

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: TE Connectivity 104450-1

The 104450-1 is the baseline part specification with active product status and established supply availability (676 units in stock). This part is suitable for applications where Tin-Lead contact finish is acceptable and RoHS compliance is not a requirement.

Substitute Selection: TE Connectivity 5-104450-1

The 5-104450-1 serves as a direct functional substitute with the following distinctions:

1. RoHS Compliance: The 5-104450-1 is RoHS Compliant, making it the appropriate selection for applications subject to RoHS regulations or customer specifications requiring lead-free construction.

2. Contact Finish: The 5-104450-1 features Tin finish (lead-free) compared to the Tin-Lead finish of the 104450-1. Both finishes maintain identical thickness specifications (100.0µin / 2.54µm) and provide equivalent electrical performance within the specified current rating (3A) and operating temperature range (-65°C ~ 105°C).

3. Supply Availability: The 5-104450-1 maintains higher inventory levels (5408 units in stock) compared to the 104450-1, providing enhanced supply chain flexibility.

Both parts are manufactured by TE Connectivity within the AMPMODU MTE series and share identical electrical, mechanical, and thermal specifications. Selection between these parts depends on regulatory compliance requirements and contact finish specifications rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Are the 104450-1 and 5-104450-1 electrically interchangeable?

A: Yes. Both parts operate at identical current ratings (3A), voltage specifications, and operating temperature ranges (-65°C ~ 105°C). The contact finish difference (Tin-Lead versus Tin) does not affect electrical performance within the specified operating parameters.

Q: What is the primary difference between these two parts?

A: The primary differences are contact finish specification and RoHS compliance status. The 104450-1 uses Tin-Lead finish and is not RoHS applicable. The 5-104450-1 uses Tin (lead-free) finish and is RoHS Compliant. Both finishes maintain identical thickness and electrical characteristics.

Q: Can I use the 5-104450-1 as a replacement for the 104450-1 in existing designs?

A: Yes. The 5-104450-1 is mechanically and electrically compatible with the 104450-1. The lead-free Tin finish of the 5-104450-1 is suitable for all applications where the Tin-Lead finish of the 104450-1 was previously used. Selection should be based on regulatory requirements and customer specifications.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical dimensions including contact length (mating: 0.230" / 5.84mm; post: 0.130" / 3.30mm), overall contact length (0.545" / 13.84mm), insulation height (0.535" / 13.60mm), and pitch spacing (0.100" / 2.54mm). They are mechanically interchangeable in board layouts and connector housings.

Q: What mounting and termination options are available?

A: Both parts support identical mounting and termination specifications: Through Hole mounting with Press-Fit and Solder termination options. The Latch Holder fastening type and Shrouded 4-Wall configuration are consistent across both parts.

Q: Which part should I select for new designs?

A: For new designs, the 5-104450-1 is recommended due to RoHS Compliance status and higher inventory availability. The lead-free Tin finish meets current industry standards and regulatory requirements. The 104450-1 remains suitable for applications where RoHS compliance is not required and Tin-Lead finish is acceptable.

Q: Are there any temperature or environmental limitations that differ between these parts?

A: No. Both parts operate across the identical temperature range (-65°C ~ 105°C) and maintain the same UL94 V-0 flammability rating. Moisture Sensitivity Level (MSL) is identical at Level 1 (Unlimited) for both parts.

Q: What is the current rating for these connectors?

A: Both the 104450-1 and 5-104450-1 are rated for 3A continuous current. This rating applies to each individual contact within the 2-position connector configuration.
