• Pitch - Mating: 0.100" (2.54mm)
• Number of positions: 14
• Number of rows: 2
• Row spacing - Mating: 0.100" (2.54mm)
• Mounting type: Through Hole
• Termination: Solder
• Fastening type: Push-Pull
• Contact shape: Square
• Insulation color: Black
• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)

Secondary Compatibility Factors:

• Contact length variations within mechanical tolerance
• Contact finish composition (gold, tin, or combinations)
• Insulation material type (thermoplastic, LCP, PBT)
• Operating temperature range (must encompass or exceed -65°C to 105°C minimum)
• Current and voltage ratings (must meet or exceed 3A and 30VAC)

Variations in contact finish thickness, post length, and insulation material do not affect functional interchangeability when the primary matching criteria are satisfied.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Compliance):

The Molex C-Grid 70280 series (part numbers 0010897140, 0010897141, 0010897142) and Molex C-Grid 70287 series (0702871103) are fully compatible substitutes. All Molex variants are ROHS3 compliant and REACH unaffected, providing regulatory advantages over the original TE Connectivity part. These parts maintain identical pitch, position count, row spacing, and mounting specifications. Inventory availability for Molex parts ranges from 1,491 to 6,964 units, providing superior supply chain flexibility.

The Amphenol ICC (FCI) BERGSTIK® series part 54102-S0807LF is an active substitute with RoHS compliance and REACH affected status. This part matches the original specification for current rating (3A per contact) and operating temperature range (-65°C to 125°C), exceeding the original -65°C to 105°C requirement. The part features phosphor bronze contacts with gold mating finish and tin post finish.

The Samtec TSW series (TSW-107-07-G-D-006 and TSW-107-07-L-D-LL) are active substitutes with ROHS3 compliance and REACH unaffected status. Both parts feature extended operating temperature ranges (-55°C to 125°C) and phosphor bronze contacts with gold mating finish. The TSW-107-07-L-D-LL variant includes kinked pin termination for enhanced mechanical retention.

Secondary Substitutes (Limited Applicability):

The 3M 961214-6404-AR is an active substitute with RoHS compliance. However, the current rating of 2A is below the original 3A specification, limiting applicability to lower-current applications. The operating temperature range (-25°C to 105°C) does not extend to the original -65°C minimum.

The Amphenol ICC (FCI) BERGSTIK® series part 54102-T06-07 is obsolete and should not be selected for new designs, despite maintaining mechanical and electrical compatibility with the original part.

Compliance Considerations:

For applications requiring RoHS compliance, all Molex variants, Amphenol 54102-S0807LF, 3M 961214-6404-AR, and Samtec TSW series are suitable. For applications requiring REACH unaffected status, Molex variants and Samtec TSW series are preferred.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine if a part can substitute for the TE Connectivity 146090-7?

A: The following parameters must match exactly: connector type (Header, Breakaway), contact type (Male Pin), pitch (0.100" / 2.54mm), number of positions (14), number of rows (2), row spacing (0.100" / 2.54mm), mounting type (Through Hole), termination (Solder), fastening type (Push-Pull), contact shape (Square), insulation color (Black), and material flammability rating (UL94 V-0). All listed substitute parts satisfy these requirements.

Q: Can I use a substitute part with a different contact material (phosphor bronze vs. copper alloy)?

A: Yes. Both phosphor bronze and copper alloy contacts are functionally compatible for this application. The contact material does not affect the electrical interface or mechanical mating characteristics. Phosphor bronze contacts (used in Amphenol and Samtec parts) provide equivalent performance to copper alloy contacts (used in TE Connectivity and Molex parts).

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

A: Kinked pin termination (used in Molex 0702871103 and Samtec TSW-107-07-L-D-LL) provides enhanced mechanical retention during PCB assembly by creating a barbed or kinked section that resists pull-out forces. Standard solder termination relies solely on solder joint strength. Both termination types are electrically equivalent and mechanically compatible with standard PCB through-holes.

Q: Are there RoHS compliance differences between the original part and substitutes?

A: Yes. The original TE Connectivity 146090-7 is RoHS non-compliant. All Molex variants (0010897140, 0010897141, 0010897142, 0702871103) are ROHS3 compliant. Amphenol 54102-S0807LF is RoHS compliant. Samtec TSW series (TSW-107-07-G-D-006, TSW-107-07-L-D-LL) are ROHS3 compliant. For applications requiring RoHS compliance, these substitutes are necessary.

Q: What is the difference between REACH affected and REACH unaffected status?

A: REACH affected status indicates the part may contain substances of very high concern (SVHC) requiring declaration and potential restrictions. REACH unaffected status indicates the part does not contain listed SVHC substances. Molex and Samtec parts are REACH unaffected, while TE Connectivity and Amphenol parts are REACH affected. For applications subject to REACH regulations, Molex and Samtec substitutes are preferred.

Q: Can I substitute the 3M 961214-6404-AR for the original part in all applications?

A: No. The 3M part has a current rating of 2A, which is below the original 3A specification. This part is suitable only for applications requiring 2A or less. Additionally, the operating temperature range (-25°C to 105°C) does not extend to the original -65°C minimum, limiting use in low-temperature environments.

Q: What is the difference between contact finish thickness specifications?

A: Contact finish thickness affects durability and wear resistance but does not impact electrical functionality. The original TE Connectivity part specifies 5.00µin (0.127µm) gold mating finish and 100.0µin (2.54µm) tin-lead post finish. Substitute parts vary in finish thickness; for example, Molex 0010897140 specifies 30.0µin (0.76µm) gold mating finish. These variations do not affect interchangeability for standard applications.

Q: Are there inventory availability differences between the original part and substitutes?

A: Yes. The original TE Connectivity 146090-7 has 704 units in stock. Molex 0010897140 has the highest inventory at 6,964 units. Other substitutes range from 847 to 3,150 units. For applications requiring immediate availability or large-volume procurement, Molex variants provide superior supply chain flexibility.

Q: Can I use a substitute part with a different insulation material (LCP vs. thermoplastic vs. PBT)?

A: Yes. Liquid Crystal Polymer (LCP), thermoplastic, and Polybutylene Terephthalate (PBT) insulation materials are functionally equivalent for this connector application. All materials meet UL94 V-0 flammability requirements. Material selection does not affect electrical performance or mechanical compatibility.

Q: What is the significance of "Number of Positions Loaded" specification?

A: This parameter indicates how many of the 14 available positions contain contacts. The original TE Connectivity part and most substitutes have all 14 positions loaded. The Samtec TSW-107-07-G-D-006 has only 13 positions loaded, meaning one position is empty. This does not affect compatibility if your application uses 13 or fewer positions.
