Substitute Part Grouping Explanation

Substitution of the obsolete 104433-1 with the active 5-146252-1 is based on strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Identical connector type (Header, Breakaway)
• Matching position count (2 positions, 2 rows)
• Identical row spacing (0.100" / 2.54mm)
• Identical contact dimensions (mating length, post length, overall length)
• Identical insulation height and contact shape

Electrical Compatibility:

• Identical contact type (Male Pin)
• Identical current rating (3A)
• Identical operating temperature range (-65°C ~ 105°C)
• Identical material flammability rating (UL94 V-0)

Mounting Compatibility:

• Identical mounting type (Through Hole)
• Identical fastening type (Push-Pull)
• Identical series designation (AMPMODU Mod II)

Differences Noted:

• Termination method: Main part includes Press-Fit option; substitute is Solder only
• Insulation material: Main part uses Thermoplastic; substitute uses Liquid Crystal Polymer (LCP)
• Contact finish - Post: Main part is Tin-Lead; substitute is Tin
• Product status: Main part is Obsolete; substitute is Active
• RoHS compliance: Main part is non-compliant; substitute is compliant

Parameter Comparison

Engineering Selection Recommendations

The 5-146252-1 serves as the direct active equivalent for the obsolete 104433-1. Selection of this substitute is supported by the following engineering factors:

Product Status Alignment: The 104433-1 is classified as obsolete, creating supply chain constraints. The 5-146252-1 maintains active product status with significantly higher inventory availability (41,534 units versus 757 units), ensuring long-term procurement viability.

Compliance Enhancement: The substitute part achieves RoHS compliance, whereas the main part is RoHS non-compliant. This compliance improvement aligns with current regulatory requirements for electronic components in regulated markets.

Mechanical and Electrical Equivalence: All critical mechanical dimensions and electrical parameters remain identical between the two parts. The connector maintains identical pitch, contact geometry, current rating, voltage capability, and operating temperature range.

Material Specification Differences: The substitute employs Liquid Crystal Polymer (LCP) insulation material in place of Thermoplastic. LCP provides enhanced thermal stability and dimensional consistency. The contact finish on the post changes from Tin-Lead to Tin, eliminating lead content and supporting RoHS compliance objectives.

Termination Method Consideration: The main part supports both Press-Fit and Solder termination methods. The substitute supports Solder termination only. Applications requiring Press-Fit termination require evaluation of alternative solutions.

Frequently Asked Questions (FAQ)

Q: Can the 5-146252-1 be used as a direct replacement for the 104433-1 in existing designs?

A: The 5-146252-1 provides direct mechanical and electrical compatibility for applications using solder termination. All contact dimensions, pitch spacing, current ratings, and operating temperature ranges are identical. Applications utilizing Press-Fit termination require design modification or alternative component selection.

Q: What is the significance of the insulation material change from Thermoplastic to Liquid Crystal Polymer (LCP)?

A: Liquid Crystal Polymer provides superior thermal stability and dimensional consistency compared to standard Thermoplastic materials. This material change supports improved long-term reliability and performance consistency across the operating temperature range of -65°C to 105°C.

Q: Does the elimination of lead in the post contact finish affect electrical performance?

A: The change from Tin-Lead to Tin contact finish on the post does not affect electrical performance. Both finishes maintain identical contact finish thickness (100.0µin / 2.54µm) and provide equivalent electrical conductivity. The change supports RoHS compliance requirements.

Q: Are there inventory implications for transitioning from 104433-1 to 5-146252-1?

A: The 5-146252-1 maintains significantly higher inventory levels (41,534 units) compared to the obsolete 104433-1 (757 units). This inventory differential ensures sustained availability for ongoing production requirements and reduces supply chain risk.

Q: What packaging differences exist between these parts?

A: The main part 104433-1 does not specify packaging information. The substitute 5-146252-1 is supplied in Bulk packaging. Confirm bulk packaging compatibility with procurement and assembly processes.

Q: Is the 5-146252-1 suitable for applications requiring RoHS compliance?

A: Yes. The 5-146252-1 is RoHS compliant, whereas the 104433-1 is RoHS non-compliant. This compliance status makes the substitute appropriate for applications subject to RoHS regulatory requirements.

Q: Are the electrical ratings identical between the two parts?

A: The current rating (3A) and operating temperature range (-65°C to 105°C) are identical. The main part specifies a voltage rating of 30VAC; the substitute does not specify voltage rating in the provided data. Confirm voltage requirements with application specifications.
