Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5-146311-7 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 14
• 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, Right Angle
• Fastening Type: Push-Pull
• Contact Shape: Square
• Insulation Color: Black

Acceptable Variation Parameters:

• Termination method (Press-Fit/Solder vs. Solder only)
• Contact finish thickness (within functional tolerance)
• Insulation material composition (Thermoplastic vs. Thermoplastic Glass Filled)
• Operating temperature range (provided minimum meets or exceeds -65°C and maximum meets or exceeds 105°C)
• Product status (Active substitutes acceptable for Obsolete main part)
• RoHS compliance status (both compliant and non-compliant variants listed)

Three substitute parts meet these criteria: TE Connectivity 5-146309-7 (MFR Recommended), 3M 2314-5221-TG, and Hirose Electric A1-14PA-2.54DS(71).

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 5-146309-7 (MFR Recommended Substitute)

The 5-146309-7 is the manufacturer-recommended substitute for the obsolete 5-146311-7. Both components are from the same AMPMODU Mod II series and share identical mechanical and electrical specifications for mating contact length, post length, and insulation height. The primary difference is termination method: the 5-146309-7 features solder termination only, whereas the original part supports both press-fit and solder termination. The 5-146309-7 maintains active product status and ROHS3 compliance. This substitute is optimal for direct replacement in applications where solder termination is acceptable.

3M 2314-5221-TG (Cross-Manufacturer Substitute)

The 2314-5221-TG from 3M's 2300 series provides functional equivalence with identical pitch, position count, and row configuration. This part maintains the same contact length specifications and gold mating finish. Operating temperature range extends to -55°C minimum (versus -65°C for the original), which is acceptable for most industrial applications. The 2314-5221-TG carries UL94 V-0 flammability rating and 3A current rating matching the original specification. RoHS non-compliance status requires evaluation against procurement requirements. This substitute is suitable for applications where cross-manufacturer sourcing is acceptable and RoHS compliance is not mandated.

Hirose Electric A1-14PA-2.54DS(71) (Alternative Substitute)

The A1-14PA-2.54DS(71) from Hirose Electric's A1 series meets all critical dimensional and electrical parameters. Contact material differs (brass versus copper alloy), and contact length specifications vary slightly (0.236" mating versus 0.318" for the original). Operating temperature maximum is 85°C, which is lower than the original specification of 105°C. This part is ROHS3 compliant and carries UL94 V-0 rating. The Hirose substitute is applicable in applications where the reduced maximum operating temperature is acceptable and where Hirose connector ecosystem integration is preferred.

Frequently Asked Questions (FAQ)

Q: Can the 5-146309-7 be used as a direct replacement for the 5-146311-7?

A: The 5-146309-7 is functionally equivalent for applications requiring solder termination. The original part supports both press-fit and solder termination, while the substitute supports solder termination only. If press-fit termination is required, the 5-146309-7 is not suitable. Both parts share identical mating contact length (0.318"), post length (0.110"), and insulation height (0.238"), ensuring mechanical compatibility with existing PCB layouts and mating connectors.

Q: What are the key differences between the TE Connectivity and 3M substitutes?

A: Both the 5-146309-7 (TE) and 2314-5221-TG (3M) provide identical pitch, position count, and contact configuration. The 3M part operates to a minimum of -55°C versus -65°C for the TE part. The 3M part carries RoHS non-compliance status, whereas the TE substitute is ROHS3 compliant. Contact finish thickness on the mating surface differs: 3.00µin for the TE part versus 10.0µin for the 3M part. Both maintain 3A current rating and UL94 V-0 flammability rating.

Q: Is the Hirose A1-14PA-2.54DS(71) suitable for high-temperature applications?

A: The Hirose part operates to a maximum of 85°C, which is 20°C lower than the original 5-146311-7 specification of 105°C. Applications requiring sustained operation above 85°C should use either the TE Connectivity 5-146309-7 or the 3M 2314-5221-TG. The Hirose substitute is appropriate for applications with maximum operating temperatures at or below 85°C.

Q: What is the significance of the contact material difference between substitutes?

A: The original 5-146311-7 and most substitutes use copper alloy contacts. The Hirose A1-14PA-2.54DS(71) uses brass contacts. Both materials provide adequate electrical conductivity and contact reliability for 3A current applications. Brass offers slightly different mechanical properties and corrosion resistance characteristics. Material selection does not affect electrical compatibility with standard mating connectors at the specified current and voltage ratings.

Q: Are all substitutes RoHS compliant?

A: The TE Connectivity 5-146309-7 and Hirose A1-14PA-2.54DS(71) are both ROHS3 compliant. The 3M 2314-5221-TG is RoHS non-compliant. Applications subject to RoHS requirements should use either the TE or Hirose substitute. The original 5-146311-7 is RoHS compliant, and the TE substitute maintains this compliance status.

Q: Can these substitutes be used interchangeably in the same application?

A: Substitutes are interchangeable only when all application requirements are met. The TE Connectivity 5-146309-7 is the primary substitute for direct replacement. The 3M and Hirose parts are suitable alternatives when their specific parameter variations (operating temperature range, RoHS status, contact material) align with application requirements. PCB layout compatibility is maintained across all substitutes due to identical pitch and position configuration.

Q: What packaging format is available for the Hirose substitute?

A: The Hirose A1-14PA-2.54DS(71) is supplied in Tray packaging. The TE Connectivity substitutes and 3M part packaging information is not specified in the provided data. Packaging format may affect handling, storage, and assembly processes and should be confirmed with the supplier for specific procurement requirements.
