Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 104433-5 is determined by strict alignment with the following critical parameters:

Primary Compatibility Criteria:

• Connector type classification (Header)
• Contact type (Male Pin)
• Number of positions (10)
• Number of rows (2)
• Pitch - mating dimension (0.100" / 2.54mm)
• Row spacing - mating dimension (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Current rating (3A minimum)
• Material flammability rating (UL94 V-0)

Secondary Compatibility Considerations:

• Operating temperature range (minimum -55°C to 85°C acceptable for most applications)
• Contact finish on mating surface (Gold preferred for signal integrity)
• Termination method compatibility (Solder or Press-Fit acceptable)

The identified substitute parts meet these criteria while offering improved product status or compliance characteristics compared to the obsolete 104433-5.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 5-146252-5

The 5-146252-5 is the manufacturer-recommended substitute for the obsolete 104433-5. This part maintains identical electrical and mechanical specifications including pitch, row spacing, contact dimensions, current rating, and operating temperature range. The 5-146252-5 is classified as an active product with ROHS3 compliance, addressing regulatory requirements that the original part does not meet. The insulation material upgrade from thermoplastic to Liquid Crystal Polymer (LCP) provides enhanced thermal and chemical resistance. Termination is limited to solder-only, eliminating press-fit capability present in the original part. This substitution is direct for applications where solder termination is acceptable.

Secondary Recommendation: Hirose A1-10PA-2.54DSA(71)

The A1-10PA-2.54DSA(71) provides an alternative from a different manufacturer while maintaining core compatibility parameters. This part is active and ROHS3 compliant. Notable differences include reduced contact mating length (0.236" versus 0.318"), reduced overall contact length (0.454" versus 0.533"), and increased insulation height (0.100" versus 0.090"). The operating temperature range is narrower (-55°C to 85°C versus -65°C to 105°C). Contact material is brass rather than copper alloy, and contact finish thickness on the mating surface is reduced (8.00µin versus 15.0µin). These dimensional and material differences may affect mechanical fit and signal integrity in applications with tight tolerances or demanding environmental conditions. This option is suitable for applications where the narrower temperature range and reduced contact dimensions are acceptable.

Compliance Consideration:

Both substitute parts achieve ROHS3 compliance, whereas the original 104433-5 is RoHS non-compliant. For applications subject to RoHS regulations, either substitute part is required.

Frequently Asked Questions (FAQ)

Q: Can the 5-146252-5 directly replace the 104433-5 in existing designs?

A: The 5-146252-5 maintains identical pitch (0.100" / 2.54mm), row spacing, contact dimensions, current rating (3A), and operating temperature range (-65°C to 105°C). Direct mechanical and electrical compatibility is established. The primary design consideration is termination method: the 5-146252-5 supports solder termination only, whereas the original part supports both press-fit and solder. If the original design uses press-fit termination, assembly process modification is required.

Q: What are the key dimensional differences between the 5-146252-5 and the A1-10PA-2.54DSA(71)?

A: Contact mating length differs by 0.082" (2.08mm), with the A1-10PA-2.54DSA(71) being shorter. Overall contact length differs by 0.079" (2.01mm). Insulation height differs by 0.010" (0.25mm). These differences may affect mechanical fit in applications with constrained board spacing or mating connector geometry. Verification against specific application requirements is necessary.

Q: Are there temperature range limitations with the Hirose A1-10PA-2.54DSA(71)?

A: The A1-10PA-2.54DSA(71) operates from -55°C to 85°C, compared to the original part's -65°C to 105°C range. Applications requiring operation below -55°C or above 85°C must use the TE Connectivity 5-146252-5 or original 104433-5.

Q: What is the difference in contact finish thickness between the substitute parts?

A: The 104433-5 and 5-146252-5 both specify 15.0µin (0.38µm) gold finish on mating contacts. The A1-10PA-2.54DSA(71) specifies 8.00µin (0.203µm), approximately 47% thinner. Thinner gold plating may affect contact resistance and wear characteristics in high-cycle mating applications.

Q: Does the change from thermoplastic to LCP insulation material in the 5-146252-5 affect compatibility?

A: Liquid Crystal Polymer (LCP) provides superior thermal stability and chemical resistance compared to thermoplastic. This material upgrade enhances reliability in demanding environments. No compatibility issues arise from this material change; it represents an improvement in the substitute part.

Q: What packaging options are available for these parts?

A: The 104433-5 packaging is not specified. The 5-146252-5 is supplied in bulk packaging. The A1-10PA-2.54DSA(71) is supplied in tray packaging. Packaging selection may affect handling, storage, and assembly process integration.

Q: Are all three parts RoHS compliant?

A: The 104433-5 is RoHS non-compliant. Both the 5-146252-5 and A1-10PA-2.54DSA(71) are ROHS3 compliant. For applications subject to RoHS regulations, either substitute part is required.

Q: What is the voltage rating difference between the parts?

A: The 104433-5 specifies 30VAC. The 5-146252-5 does not specify a voltage rating. The A1-10PA-2.54DSA(71) specifies 200V. For applications requiring voltage ratings above 30VAC, the A1-10PA-2.54DSA(71) provides higher rated capacity.
