• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Fastening Type: Push-Pull
• Material Flammability Rating: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Compatibility Parameters:

• Current Rating: 3A or higher
• Operating Temperature Range: Must encompass -65°C to 105°C minimum
• Contact Shape: Square
• Insulation Color: Black
• Termination: Solder-compatible

The substitute parts identified below satisfy these core electrical and mechanical parameters, enabling direct functional replacement in applications originally designed for the 104433-2.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: TE Connectivity AMP Connectors 5-146252-2

The 5-146252-2 is the manufacturer-recommended substitute for the obsolete 104433-2. Both components share identical series designation (AMPMODU Mod II), electrical specifications, and mechanical configuration. The 5-146252-2 maintains active product status and achieves ROHS3 compliance, addressing regulatory requirements for new designs. This part is the preferred selection for direct replacement applications where design continuity and supply chain stability are priorities.

Secondary Alternatives: Amphenol ICC (FCI) BERGSTIK® Series

The 67998-204HLF and 77313-122-04LF represent cross-manufacturer alternatives from the Amphenol ICC (FCI) product line. Both parts satisfy core electrical and mechanical substitution criteria and maintain active product status with RoHS compliance. These alternatives are suitable for applications where multi-source qualification is required or where Amphenol ICC components are preferred within existing supply chains.

Compliance Considerations:

The 104433-2 is RoHS non-compliant. All identified substitute parts (5-146252-2, 67998-204HLF, 77313-122-04LF) achieve RoHS compliance, supporting transition to current regulatory standards. Applications subject to RoHS requirements must utilize one of the compliant substitute parts.

Thermal Performance:

The 77313-122-04LF extends the operating temperature range to -65°C ~ 130°C, providing enhanced thermal margin compared to the original 104433-2 specification of -65°C ~ 105°C. This extended range is available for applications requiring elevated temperature performance.

Frequently Asked Questions (FAQ)

Q: Can the 5-146252-2 directly replace the 104433-2 in existing designs?

A: Yes. The 5-146252-2 maintains identical pitch spacing (0.100" / 2.54mm), position count (4), row configuration (2), and electrical ratings (3A, 30VAC equivalent). Both components are AMPMODU Mod II series headers with matching mechanical footprints and push-pull fastening. The primary difference is product status (active versus obsolete) and RoHS compliance improvement.

Q: What are the key differences between the TE Connectivity and Amphenol ICC alternatives?

A: The TE Connectivity 5-146252-2 maintains series continuity with the original part. The Amphenol ICC alternatives (67998-204HLF and 77313-122-04LF) utilize different series designations (BERGSTIK® II and BERGSTIK® respectively) and employ phosphor bronze contact material instead of copper alloy. All three alternatives satisfy the core 0.100" pitch, 4-position, 2-row, through-hole mounting requirements. Contact material differences do not affect functional compatibility in standard applications.

Q: Are there packaging differences between these substitute parts?

A: The 104433-2 original specification does not indicate packaging type. All identified substitutes are supplied in bulk packaging, suitable for standard procurement and assembly workflows. Packaging format does not affect electrical or mechanical compatibility.

Q: Does the 67998-204HLF higher current rating (5A versus 3A) affect compatibility?

A: No. The 67998-204HLF 5A current rating exceeds the original 3A specification, providing additional design margin. Applications designed for 3A operation remain fully compatible. The higher rating does not introduce incompatibility; it represents enhanced capability.

Q: What is the significance of the extended temperature range in the 77313-122-04LF?

A: The 77313-122-04LF operates to -65°C ~ 130°C, compared to the original -65°C ~ 105°C specification. This extended upper temperature limit accommodates applications requiring sustained operation at elevated temperatures. For applications within the original -65°C ~ 105°C range, this extended capability provides additional thermal margin without affecting compatibility.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 5-146252-2 achieves ROHS3 compliance. The 67998-204HLF and 77313-122-04LF are RoHS compliant. The original 104433-2 is RoHS non-compliant. Applications subject to RoHS regulatory requirements must transition to one of the compliant substitute parts.

Q: Can these connectors be used interchangeably in the same circuit board design?

A: Yes, within the constraints of the specified parameters. All substitute parts maintain 0.100" (2.54mm) pitch spacing and 2-row, 4-position configuration, enabling direct PCB footprint compatibility. Termination method (solder) is consistent across all parts. Mechanical and electrical interchangeability is confirmed for applications within the specified operating parameters.
