TE Connectivity 104363-3 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 104363-3 is a vertical rectangular connector header designed for through-hole mounting applications. This shrouded 4-position header operates at 0.100" (2.54mm) pitch and accommodates male pin contacts with gold-plated mating surfaces. The connector is classified as Active product status and serves applications in automotive, general purpose, medical, and telecommunications sectors. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or specific compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers is determined by strict equivalence across electrical and mechanical parameters. The primary criteria for substitution include:

Electrical Parameters:

• Contact type (Male Pin)
• Number of positions (4)
• Mating pitch (0.100" / 2.54mm)
• Current rating (3A)
• Operating temperature range (-65°C ~ 105°C)
• Contact finish on mating surface (Gold)

Mechanical Parameters:

• Connector type (Header)
• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Contact shape (Square)
• Insulation material (Thermoplastic)
• Fastening type (Latch Holder)

Compliance Parameters:

• Material flammability rating (UL94 V-0)
• Series compatibility (AMPMODU MTE)

The substitute part 5-104363-3 maintains full equivalence across all critical electrical and mechanical parameters. Differences in RoHS status and contact finish post material (Tin versus Tin-Lead) do not affect functional interchangeability in the specified applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 104363-3 and 5-104363-3 are Active product status connectors suitable for direct substitution in rectangular connector header applications. The primary distinction between these parts is the RoHS compliance status and contact finish post material.

The 5-104363-3 variant is RoHS Compliant and features Tin contact finish on the post, whereas the 104363-3 is not RoHS applicable and uses Tin-Lead contact finish. For applications requiring RoHS compliance, the 5-104363-3 is the appropriate selection. Both parts maintain identical electrical performance, mechanical dimensions, and thermal operating characteristics across the -65°C to 105°C range.

The 5-104363-3 demonstrates higher current inventory availability (2300 Pcs) compared to the 104363-3 (963 Pcs), which may influence supply chain decisions. Both parts are packaged in tubes and are suitable for automotive, general purpose, medical, and telecommunications applications.

Frequently Asked Questions (FAQ)

Q: Are the 104363-3 and 5-104363-3 fully interchangeable?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical connector type, contact configuration, mating pitch, shrouding, mounting method, and operating temperature range. The primary difference is RoHS compliance status and contact finish post material, which do not affect functional interchangeability.

Q: What is the significance of the contact finish difference between Tin-Lead and Tin?

A: The contact finish post material (Tin-Lead versus Tin) does not affect the electrical or mechanical performance of the connector header. Both finishes provide equivalent solder joint reliability and thermal cycling performance. The Tin finish on the 5-104363-3 reflects RoHS compliance requirements.

Q: Can I use the 5-104363-3 in applications originally specified for the 104363-3?

A: Yes. The 5-104363-3 maintains full compatibility with all applications specified for the 104363-3, including automotive, general purpose, medical, and telecommunications sectors. The RoHS Compliant variant does not introduce any functional limitations.

Q: What is the mating pitch, and why is it important for substitution?

A: The mating pitch is 0.100" (2.54mm), which defines the center-to-center spacing between adjacent contacts. This parameter is critical for substitution because connectors with different pitches are not mechanically compatible. Both substitute parts maintain identical 0.100" pitch specifications.

Q: Are there any packaging differences between these parts?

A: Both the 104363-3 and 5-104363-3 are packaged in tubes. No packaging differences exist that would affect component handling, storage, or installation procedures.

Q: What is the current rating, and does it apply to all four positions?

A: The current rating is 3A per contact. This rating applies to each of the four positions in the connector header. The rating is identical across both substitute parts.

Q: What operating temperature range is supported?

A: Both parts operate across the temperature range of -65°C to 105°C. This range is suitable for automotive, medical, and general industrial applications requiring extended thermal performance.

Q: What does UL94 V-0 flammability rating indicate?

A: UL94 V-0 is the highest flammability classification for thermoplastic materials. It indicates that the insulation material will not propagate flame and meets stringent fire safety requirements. Both parts carry this identical certification.

Q: Is the keying slot present on both substitute parts?

A: Yes. Both the 104363-3 and 5-104363-3 include a keying slot feature, which provides polarization and prevents incorrect mating orientation.

Q: What is the Moisture Sensitivity Level (MSL), and what does it mean?

A: Both parts have MSL 1 (Unlimited), which indicates unlimited shelf life without special moisture control measures. These connectors do not require dry-pack storage or baking procedures prior to assembly.
