Key Parameters

Substitute Part Grouping Explanation

Substitution of the 146131-6 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Connector type (Header, Breakaway)
• Number of positions (14)
• Number of rows (2)
• Pitch spacing (0.100" / 2.54mm)
• Row spacing (0.100" / 2.54mm)
• Mounting type (Surface Mount)
• Termination method (Solder)

Electrical Compatibility:

• Contact type (Male Pin)
• Current rating (3A)
• Voltage rating (30VAC)
• Operating temperature range (-65°C ~ 125°C)

Material & Construction:

• Insulation material (Liquid Crystal Polymer - LCP)
• Contact material (Copper Alloy)
• Flammability rating (UL94 V-0)

The substitute part 5-146131-6 maintains full equivalence across all mechanical and electrical parameters. The primary distinction is product status (Active vs. Obsolete) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 5-146131-6

The part 5-146131-6 is the direct active equivalent of the obsolete 146131-6. This substitute maintains complete mechanical and electrical compatibility across all specified parameters. The substitute is classified as Active product status, ensuring ongoing availability and manufacturing support.

Compliance Considerations:

The 146131-6 is RoHS non-compliant, while the substitute 5-146131-6 is RoHS Compliant. For applications subject to RoHS regulations (EU Directive 2011/65/EU and amendments), the substitute part satisfies compliance requirements. The contact finish post material differs between the two parts: the original uses Tin-Lead, while the substitute uses Tin. This change aligns with RoHS compliance objectives and does not affect electrical or mechanical performance within the specified operating parameters.

Packaging Difference:

The substitute part 5-146131-6 is supplied in Tube packaging, whereas the original part packaging is not specified. This packaging difference does not affect component functionality or performance.

Inventory & Availability:

Both parts maintain current inventory stock levels (1120 Pcs for 146131-6; 1064 Pcs for 5-146131-6), supporting immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can 5-146131-6 be used as a direct replacement for 146131-6 in existing designs?

A: Yes. The 5-146131-6 maintains full mechanical and electrical equivalence with the 146131-6 across all critical parameters including connector type, position count, pitch spacing, mounting type, current rating, voltage rating, and operating temperature range. No design modifications are required.

Q: What is the significance of the contact finish difference (Tin-Lead vs. Tin)?

A: The original part uses Tin-Lead contact finish on the post, while the substitute uses Tin. Both finishes provide equivalent electrical conductivity and solderability. The change to Tin reflects RoHS compliance requirements and does not impact electrical performance or mechanical compatibility.

Q: Why is the original part classified as obsolete?

A: The 146131-6 carries an obsolete product status, indicating that TE Connectivity has discontinued active manufacturing and support for this specific part number. The substitute 5-146131-6 is the active equivalent maintained by the manufacturer for ongoing applications.

Q: Does the RoHS compliance difference affect component selection?

A: RoHS compliance status is relevant for applications subject to EU Directive 2011/65/EU or equivalent regional regulations. The substitute part 5-146131-6 is RoHS Compliant, making it suitable for regulated markets. The original part is RoHS non-compliant and may not be acceptable for new designs in regulated regions.

Q: Are there packaging considerations when switching from 146131-6 to 5-146131-6?

A: The substitute part is supplied in Tube packaging, while the original part packaging is not specified. Tube packaging is a standard format for surface mount connectors and does not affect component performance or PCB assembly compatibility. Verify packaging requirements with your procurement or assembly process specifications.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence across mechanical parameters (connector type, position count, rows, pitch spacing, mounting type, termination method) and electrical parameters (contact type, current rating, voltage rating, operating temperature range). Material composition, contact finish specifications, and flammability ratings must also match. The 5-146131-6 meets all these criteria for the 146131-6.

Q: Is the 5-146131-6 available in the same quantity as the original part?

A: Current inventory shows 1064 Pcs of 5-146131-6 in stock compared to 1120 Pcs of the original 146131-6. Both quantities support standard procurement volumes. Verify availability with your supplier for specific order quantities and lead times.
