Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 103327-1 is determined by strict equivalence across the following critical parameters:

• Series compatibility: AMPMODU Mod II
• Connector type: Header, Breakaway
• Contact type: Male Pin
• Number of positions: 1
• Number of rows: 1
• Mounting type: Through Hole
• Termination method: Solder
• Fastening type: Push-Pull
• Contact dimensions: Mating length 0.230" (5.84mm), Post length 0.120" (3.05mm), Overall length 0.440" (11.18mm)
• Insulation height: 0.090" (2.29mm)
• Contact shape: Square
• Contact material: Copper Alloy
• Operating temperature range: -65°C ~ 105°C
• Current rating: 3A
• Material flammability: UL94 V-0
• Insulation color: Black
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part 5-146278-1 meets all these critical parameters and is therefore electrically and mechanically equivalent to the 103327-1.

Parameter Comparison

Engineering Selection Recommendations

The 103327-1 is obsolete and no longer in active production. The substitute part 5-146278-1 provides functional and mechanical equivalence while offering improved compliance status.

Key selection factors:

• 5-146278-1 is an active product with significantly higher inventory availability (40,294 pcs vs. 773 pcs for the obsolete 103327-1)
• 5-146278-1 is RoHS Compliant, whereas the 103327-1 is RoHS non-compliant
• Both parts maintain identical electrical and mechanical specifications across all critical parameters
• The insulation material differs (Thermoplastic vs. Liquid Crystal Polymer), and contact finish differs (Tin-Lead vs. Tin), but these variations remain within the functional equivalence envelope for this connector category
• Both parts carry identical certifications: UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity

For new designs or ongoing production requiring this connector type, 5-146278-1 is the recommended selection due to active product status and RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can 5-146278-1 directly replace 103327-1 in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: single position, male pin header, through-hole mount, push-pull fastening, identical contact dimensions, and identical current and temperature ratings. The parts are interchangeable at the functional level.

Q: What are the differences between these two parts?

A: The primary differences are product status, compliance, and material composition. The 103327-1 uses Thermoplastic insulation with Tin-Lead contact finish and is RoHS non-compliant. The 5-146278-1 uses Liquid Crystal Polymer (LCP) insulation with Tin contact finish and is RoHS Compliant. These differences do not affect electrical or mechanical compatibility.

Q: Why is the insulation material different?

A: The insulation material change from Thermoplastic to Liquid Crystal Polymer (LCP) reflects manufacturing evolution within the AMPMODU Mod II series. LCP provides enhanced thermal and mechanical properties while maintaining the same functional performance envelope. Both materials meet UL94 V-0 flammability requirements.

Q: Does the contact finish change from Tin-Lead to Tin affect performance?

A: No. Both finishes provide equivalent electrical conductivity and corrosion resistance for this connector application. The shift to Tin reflects RoHS compliance requirements and does not impact functional performance.

Q: What is the inventory situation for these parts?

A: The 103327-1 (obsolete) has 773 pcs available. The 5-146278-1 (active) has 40,294 pcs available, providing significantly better supply chain continuity.

Q: Are there any packaging differences?

A: The 103327-1 packaging is listed as unspecified. The 5-146278-1 is supplied in Bulk packaging. Both are suitable for standard assembly processes.

Q: Is 5-146278-1 suitable for new product designs?

A: Yes. As an active product with RoHS compliance and superior availability, 5-146278-1 is the appropriate choice for new designs requiring single-position AMPMODU Mod II male pin headers with through-hole mounting and push-pull fastening.
