• Contact type (Male Pin)
• Position count (4 positions)
• Row configuration (2 rows)
• Mating pitch (0.100" / 2.54mm)
• Row spacing (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Termination capability (Solder)
• Fastening type (Push-Pull)
• Contact shape (Square)
• Insulation color (Black)
• Material flammability (UL94 V-0)

Electrical Compatibility Criteria:

• Current rating equal to or greater than 3A
• Voltage rating equal to or greater than 30VAC
• Operating temperature range encompassing -65°C to 105°C

Mechanical Compatibility Criteria:

• Overall contact length within acceptable tolerance
• Insulation height compatible with mating receptacles
• Contact finish (Gold on mating surface)

The identified substitute parts meet these criteria while offering active product status and improved compliance profiles.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 5-146253-2

The 5-146253-2 is the manufacturer-recommended substitute for the obsolete 104432-2. Both connectors belong to the AMPMODU Mod II series and share identical electrical and mechanical specifications. The 5-146253-2 maintains active product status, ensuring long-term availability and supply chain continuity. This part is functionally equivalent with matching pitch, position count, current rating, and operating temperature range. The primary difference is the insulation material upgrade from Thermoplastic to Liquid Crystal Polymer (LCP), which provides enhanced thermal and chemical resistance. Termination is limited to solder-only, eliminating press-fit capability present in the original part.

Secondary Recommendation: Amphenol ICC 77313-122-04LF

The 77313-122-04LF provides cross-manufacturer compatibility within the BERGSTIK® series. This part maintains the Header, Breakaway connector type and matches all critical mating parameters. The operating temperature range extends to 130°C, exceeding the original specification. Current rating and contact finish specifications align with the original part. RoHS compliance status is active, supporting modern regulatory requirements. Contact material differs (Phosphor Bronze versus Copper Alloy), providing alternative mechanical properties.

Alternative Option: Amphenol ICC 67998-204HLF

The 67998-204HLF operates within the BERGSTIK® II series and provides functional compatibility for applications not requiring breakaway capability. This part offers elevated current rating (5A) and voltage rating (110V), suitable for higher-power applications. RoHS compliance and REACH unaffected status support modern supply chain requirements. Contact material composition (Phosphor Bronze) differs from the original specification. Operating temperature range is not specified, requiring verification for temperature-critical applications.

Frequently Asked Questions (FAQ)

Q: Can the 5-146253-2 directly replace the 104432-2 in existing designs?

A: The 5-146253-2 is electrically and mechanically compatible with the 104432-2 for mating and electrical performance. The primary design consideration is termination method: the 5-146253-2 supports solder termination only, while the original part supports both press-fit and solder. If press-fit termination is required, alternative substitutes must be evaluated.

Q: What is the difference between the BERGSTIK® and BERGSTIK® II series?

A: Both series are manufactured by Amphenol ICC (FCI) and provide compatible 2.54mm pitch header connectors. The BERGSTIK® II series (67998-204HLF) represents a newer product line with enhanced specifications. The BERGSTIK® series (77313-122-04LF) maintains broader compatibility with legacy designs. Selection depends on application requirements and supply availability.

Q: Are the substitute parts RoHS compliant?

A: The 5-146253-2 RoHS status is not specified in available documentation. The 77313-122-04LF is RoHS compliant. The 67998-204HLF is RoHS compliant. For applications requiring RoHS compliance certification, the Amphenol ICC parts (77313-122-04LF and 67998-204HLF) provide documented compliance.

Q: What is the impact of insulation material differences?

A: The original 104432-2 uses Thermoplastic insulation. The 5-146253-2 upgrades to Liquid Crystal Polymer (LCP), offering superior thermal stability and chemical resistance. The 77313-122-04LF maintains Thermoplastic insulation. Material selection does not affect mating compatibility but influences long-term reliability in thermal or chemical environments.

Q: Can these connectors be used interchangeably with existing receptacles?

A: All substitute parts maintain identical mating pitch (0.100" / 2.54mm), row spacing (0.100" / 2.54mm), and contact geometry (square shape). Mating compatibility with existing receptacles is confirmed. Physical dimensions and contact engagement characteristics remain consistent across all listed alternatives.

Q: What are the packaging differences among substitute parts?

A: The 5-146253-2 is supplied in Tray packaging. The 67998-204HLF and 77313-122-04LF are supplied in Bulk packaging. Packaging selection affects handling, storage, and automated assembly processes but does not influence electrical or mechanical performance.

Q: How do contact finish specifications compare?

A: All parts feature gold mating surface finish. The 104432-2 and 5-146253-2 specify 30.0µin (0.76µm) gold thickness. The 77313-122-04LF matches this specification. The 67998-204HLF specifies 15.0µin (0.38µm), providing thinner gold plating. Post finish differs: the original part uses Tin-Lead; substitutes use Tin or unspecified finishes. These differences do not affect mating performance.

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

A: The 77313-122-04LF operates to 130°C, compared to 105°C for the original part. This extended range accommodates applications with elevated ambient or component temperatures. For applications operating within the original -65°C to 105°C range, this extended capability provides additional thermal margin without design modification.
