Key Parameters

Substitute Part Grouping Explanation

The substitute relationship between 1-103186-0 and 6-146256-0 is established on the following critical parameters that determine functional interchangeability:

• Connector Type & Contact Configuration: Both parts are Header, Breakaway connectors with Male Pin contacts
• Position Count & Pitch: Identical 20-position configuration with 0.100" (2.54mm) mating pitch and row spacing
• Electrical Ratings: Both rated for 3A current with identical operating temperature range (-65°C ~ 105°C)
• Mounting & Termination: Both use through-hole mounting with solder termination
• Physical Dimensions: Contact lengths, insulation height, and overall contact length are identical
• Safety Compliance: Both meet UL94 V-0 material flammability rating

The primary differences are material composition (Thermoplastic vs. Liquid Crystal Polymer insulation), contact finish on posts (Tin-Lead vs. Tin), and regulatory compliance status (RoHS non-compliant vs. ROHS3 Compliant).

Parameter Comparison

Engineering Selection Recommendations

The 6-146256-0 is the direct active equivalent for the obsolete 1-103186-0. Selection of the substitute part is based on the following engineering factors:

Product Status: The 1-103186-0 is obsolete, while 6-146256-0 is active and available in production quantities (2100 pcs in stock vs. 795 pcs for the original part).

Regulatory Compliance: The 6-146256-0 achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. This is significant for applications subject to RoHS directives in the EU and other regulated markets.

Material Specification: The substitute uses Liquid Crystal Polymer (LCP) insulation instead of Thermoplastic, providing improved dimensional stability and thermal performance within the identical operating temperature range.

Contact Finish: The post contact finish changes from Tin-Lead to Tin. Both finishes maintain the specified 100.0µin (2.54µm) thickness and are compatible with standard solder processes.

Functional Equivalence: All critical electrical and mechanical parameters remain identical, ensuring direct substitution in existing PCB designs and connector mating applications.

Frequently Asked Questions (FAQ)

Q: Can 6-146256-0 be used as a direct replacement for 1-103186-0 in existing designs?

A: Yes. Both parts share identical connector type, position count, pitch, mounting method, termination, current rating, and operating temperature range. The physical dimensions and contact configurations are equivalent, allowing direct substitution without PCB redesign.

Q: What is the significance of the insulation material change from Thermoplastic to LCP?

A: Liquid Crystal Polymer provides superior dimensional stability and thermal performance compared to standard Thermoplastic. Both materials meet UL94 V-0 flammability requirements and operate across the identical temperature range (-65°C ~ 105°C). The LCP material is a material upgrade that enhances long-term reliability.

Q: Does the change from Tin-Lead to Tin post finish affect solderability?

A: No. Both finishes are compatible with standard solder processes and maintain the same thickness specification (100.0µin / 2.54µm). Tin is the modern standard for lead-free applications and is fully compatible with RoHS3 compliance requirements.

Q: Why is RoHS3 compliance important for this substitution?

A: RoHS3 compliance is required for products sold in the EU and many other regulated markets. The 6-146256-0 meets these requirements, while the original 1-103186-0 does not. For new designs or applications subject to RoHS directives, the substitute part is the appropriate choice.

Q: Are there any packaging differences between these parts?

A: The 1-103186-0 packaging is listed as unspecified, while 6-146256-0 is supplied in Bulk packaging. Both parts are available in production quantities and are suitable for standard component procurement workflows.

Q: What is the MSL rating and why does it matter?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity. These connectors do not require special moisture control during storage, handling, or assembly, simplifying logistics and manufacturing processes.
