TE Connectivity 1-104351-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-104351-1 is a rectangular connector header manufactured under the AMPMODU Mod II series. This through-hole connector features 22 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing, designed for board-to-board or cable applications. The connector utilizes male pins with gold-plated mating contacts and tin-lead plated posts, rated for 3A current at 30VAC with an operating temperature range of -65°C to 105°C.

The 1-104351-1 carries an obsolete product status, making equivalent and substitute parts necessary for ongoing design support, maintenance, and production continuity. Active alternatives are available from multiple manufacturers that maintain electrical and mechanical compatibility while offering current product availability and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 1-104351-1 is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 22
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Current Rating: 3A minimum
• Material Flammability Rating: UL94 V-0

Acceptable Variation Parameters:

• Contact Finish (Mating): Gold or Tin (both acceptable for electrical compatibility)
• Operating Temperature Range: Minimum -65°C to 105°C (higher upper limits acceptable)
• Contact Material: Copper Alloy or Phosphor Bronze (both acceptable)
• RoHS Status: Compliant or non-compliant (application-dependent)

All identified substitute parts meet these mandatory parameters and are therefore electrically and mechanically compatible with the original 1-104351-1 connector.

Engineering Selection Recommendations

For RoHS Compliant Applications:

The Amphenol ICC 77313-102-22LF and all Samtec TD series alternatives (TD-111-G-A-1, TD-111-G-A-2, TD-111-T-A-1, TD-111-T-AA) are ROHS3 or RoHS Compliant, making them suitable for applications requiring regulatory compliance. The original 1-104351-1 is RoHS non-compliant and should be replaced with any of these alternatives in new designs or production requiring RoHS certification.

For Gold-Plated Mating Contacts:

The Samtec TD-111-G-A-1 and TD-111-G-A-2 provide gold-plated mating contacts matching the original 1-104351-1 specification. Both are available in active product status with adequate inventory. TD-111-G-A-1 is packaged in tubes, while TD-111-G-A-2 is available in bulk packaging.

For Tin-Plated Mating Contacts:

The Samtec TD-111-T-A-1 and TD-111-T-AA both feature tin-plated mating contacts and are available in tube packaging. These alternatives provide the highest inventory levels (1022 and 1033 units respectively) and maintain full electrical compatibility.

For Extended Operating Temperature Range:

The Amphenol ICC 77313-102-22LF supports an operating temperature range of -65°C to 130°C, exceeding the original 1-104351-1 specification of -65°C to 105°C. This alternative is suitable for applications requiring enhanced thermal performance.

For Packaging Flexibility:

Samtec TD series connectors are available in both tube and bulk packaging options, providing flexibility for different procurement and assembly workflows. The Amphenol ICC 77313-102-22LF is available in bulk packaging only.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 77313-102-22LF directly replace the TE Connectivity 1-104351-1?

A: Yes. Both connectors share identical electrical and mechanical specifications: 22 positions, 2 rows, 0.100" (2.54mm) pitch, through-hole mounting, solder termination, and 3A current rating. The 77313-102-22LF is electrically and mechanically compatible and offers active product status with RoHS compliance.

Q: What is the difference between the Samtec TD-111-G-A-1 and TD-111-G-A-2?

A: Both connectors are electrically and mechanically identical 22-position, 2-row headers with 0.100" (2.54mm) pitch and gold-plated mating contacts. The primary difference is packaging: TD-111-G-A-1 is supplied in tube packaging, while TD-111-G-A-2 is supplied in bulk packaging. Selection depends on procurement and assembly requirements.

Q: Are the Samtec TD-111-T-A-1 and TD-111-T-AA interchangeable?

A: Yes. Both connectors are electrically and mechanically identical with tin-plated mating contacts, 22 positions, 2 rows, and 0.100" (2.54mm) pitch. Both are packaged in tubes and maintain full compatibility with the original 1-104351-1 specification.

Q: Why should I choose a gold-plated contact finish over tin?

A: Contact finish selection depends on application requirements. Gold-plated contacts (TD-111-G-A-1, TD-111-G-A-2) provide enhanced corrosion resistance and are suitable for high-reliability applications. Tin-plated contacts (TD-111-T-A-1, TD-111-T-AA) are cost-effective and suitable for standard industrial applications. Both finishes maintain electrical compatibility with the original 1-104351-1.

Q: Does the Amphenol ICC 77313-102-22LF support higher temperatures than the original connector?

A: Yes. The 77313-102-22LF operates from -65°C to 130°C, compared to the original 1-104351-1 range of -65°C to 105°C. This extended upper temperature limit makes the Amphenol ICC alternative suitable for applications requiring enhanced thermal performance.

Q: Are all substitute parts RoHS compliant?

A: The Amphenol ICC 77313-102-22LF and all Samtec TD series alternatives (TD-111-G-A-1, TD-111-G-A-2, TD-111-T-A-1, TD-111-T-AA) are RoHS Compliant or ROHS3 Compliant. The original 1-104351-1 is RoHS non-compliant. For applications requiring RoHS certification, any of the substitute parts are suitable replacements.

Q: What is the difference between kinked pin and standard solder termination?

A: The original 1-104351-1 uses kinked pin solder termination, while all substitute parts use standard solder termination. Both termination methods are compatible with through-hole PCB assembly processes. Standard solder termination is the current industry standard and is used across all substitute alternatives.

Q: Can I mix and match substitute parts in the same assembly?

A: Yes. All substitute parts are electrically and mechanically compatible with each other and with the original 1-104351-1. Selection of specific alternatives should be based on contact finish requirements (gold or tin), packaging preferences (tube or bulk), and compliance certifications needed for the application.
