Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-104427-0 is determined by strict equivalence across the following critical parameters:

Primary Matching Criteria:

• Connector type: Header, Breakaway
• Contact type: Male Pin
• Pitch - Mating: 0.100" (2.54mm)
• Number of positions: 12
• Number of rows: 1
• Mounting type: Through Hole
• Current rating: 3A
• Material flammability rating: UL94 V-0

Secondary Compatibility Factors:

• Operating temperature range minimum: -65°C
• Contact finish - Mating: Gold
• Shrouding: Unshrouded
• Style: Board to Board or Cable

The substitute parts identified below meet all primary matching criteria and maintain compatibility within the secondary factors. Variations in contact material, insulation material, and post contact finish are permissible where the mating interface and electrical performance remain equivalent.

Engineering Selection Recommendations

TE Connectivity 6-146276-2 (MFR Recommended Substitute)

The 6-146276-2 is the manufacturer-recommended equivalent from TE Connectivity. This part maintains active product status and shares identical mating pitch, position count, and contact geometry with the obsolete 1-104427-0. The primary differences are the insulation material upgrade from thermoplastic to Liquid Crystal Polymer (LCP) and the elimination of press-fit termination in favor of solder-only termination. Both parts operate within the same temperature range (-65°C to 105°C) and maintain UL94 V-0 flammability compliance. The contact finish specifications remain equivalent at the mating interface. This substitute is the preferred selection for direct replacement in applications currently using the 1-104427-0.

Sullins Connector Solutions PBC12SFAN (Similar Substitute)

The PBC12SFAN provides an alternative from a different manufacturer while maintaining all critical electrical and mechanical parameters. This part is actively produced and offers an extended operating temperature range (-65°C to 125°C), providing additional thermal margin. The contact material differs (phosphor bronze versus copper alloy) and the insulation material is PBT rather than thermoplastic or LCP. The insulation height is slightly increased to 0.100" (2.54mm). The PBC12SFAN carries ROHS3 compliance, whereas the original part is RoHS non-compliant. This substitute is suitable for applications requiring cross-manufacturer sourcing or enhanced temperature performance.

Frequently Asked Questions (FAQ)

Q: Can the 6-146276-2 be used as a direct replacement for the 1-104427-0?

A: Yes. Both parts share identical mating pitch (0.100" / 2.54mm), position count (12), contact geometry, and current rating (3A). The 6-146276-2 is the manufacturer-recommended substitute and maintains equivalent electrical performance at the mating interface. The primary difference is the elimination of press-fit termination capability; the 6-146276-2 supports solder termination only.

Q: What is the significance of the insulation material change from thermoplastic to LCP in the 6-146276-2?

A: Liquid Crystal Polymer (LCP) provides improved dimensional stability and thermal performance compared to standard thermoplastic. This material upgrade does not affect compatibility with mating connectors or electrical performance. The change represents a product improvement in the active substitute.

Q: Is the PBC12SFAN compatible with the same mating connectors as the 1-104427-0?

A: Yes. The PBC12SFAN maintains the same 0.100" (2.54mm) pitch, 12-position configuration, and square contact geometry. The mating interface is compatible with connectors designed for the original part. The phosphor bronze contact material and PBT insulation do not affect mating compatibility.

Q: What is the difference in contact post length between these parts?

A: The 1-104427-0 and PBC12SFAN both have 0.120" (3.05mm) contact post length, while the 6-146276-2 has 0.125" (3.18mm). These variations fall within acceptable tolerances for through-hole PCB mounting and do not affect functional compatibility. Overall contact length differences are similarly minor (ranging from 0.528" to 0.538").

Q: Does the extended temperature range of the PBC12SFAN (-65°C to 125°C) provide any advantage?

A: The PBC12SFAN supports operation up to 125°C compared to 105°C for the original part and the 6-146276-2. This extended range provides additional thermal margin for applications operating at elevated temperatures. However, for applications within the original -65°C to 105°C range, this difference is not a functional advantage.

Q: Are there RoHS compliance considerations when selecting a substitute?

A: The original 1-104427-0 is RoHS non-compliant. The 6-146276-2 compliance status is not specified in the provided data. The PBC12SFAN is ROHS3 compliant. For applications requiring RoHS compliance, the PBC12SFAN is the appropriate selection.

Q: What is the impact of the contact finish thickness variation in the PBC12SFAN?

A: The PBC12SFAN has 10.0µin (0.25µm) gold plating on the mating contact compared to 15.0µin (0.38µm) on the original part and the 6-146276-2. Both thicknesses provide adequate corrosion protection and electrical performance for the specified 3A current rating and 30VAC voltage application.

Q: Can these parts be used interchangeably in existing designs?

A: The 6-146276-2 is the direct manufacturer substitute and is recommended for existing designs. The PBC12SFAN is functionally equivalent but represents a cross-manufacturer alternative. Both maintain the critical electrical and mechanical parameters required for compatibility with mating connectors and PCB layouts designed for the 1-104427-0.
