Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 68423-402HLF is determined by the following critical parameters:

Primary Compatibility Criteria:

• Pitch - Mating: 0.100" (2.54mm) — exact match required
• Number of Positions: 2 — exact match required
• Number of Rows: 1 — exact match required
• Connector Type: Header — exact match required
• Contact Type: Male Pin — exact match required
• Mounting Type: Through Hole, Right Angle — exact match required
• Termination: Solder — exact match required
• Fastening Type: Push-Pull — exact match required
• Contact Shape: Square — exact match required
• Material Flammability Rating: UL94 V-0 — exact match required

Secondary Compatibility Parameters:

• Contact Length - Mating: 0.318" (8.08mm) — minor variations acceptable within mechanical tolerance
• Contact Length - Post: 0.120" (3.05mm) — minor variations acceptable within mechanical tolerance
• Insulation Height: 0.095" (2.41mm) — minor variations acceptable within mechanical tolerance
• Contact Finish - Mating: Tin or Gold — both acceptable for electrical compatibility
• Contact Material: Phosphor Bronze — standard for this connector class
• Insulation Material: Thermoplastic or Polyamide — both acceptable
• Insulation Color: Black — standard requirement

All four substitute parts meet these criteria and are qualified as direct replacements.

Parameter Comparison

Engineering Selection Recommendations

77315-425-02LF (Amphenol ICC) This substitute is the manufacturer-recommended replacement from Amphenol ICC. It maintains the same series lineage (BERGSTIK®) with active product status. The part demonstrates RoHS compliance and provides specified operating temperature range (-65°C ~ 125°C) and current rating (3A per Contact). Contact length and insulation height are virtually identical to the original part. This option is preferred for applications requiring continuity with the original manufacturer ecosystem.

0022288021 (Molex KK254 Series) This Molex substitute offers active product status with ROHS3 compliance. Contact length for mating is 0.324" (8.23mm), representing a 0.006" (0.15mm) increase from the original specification. Insulation height is 0.098" (2.50mm), a 0.003" (0.09mm) increase. These dimensional variations remain within typical mechanical tolerances for board-to-board connector applications. The part supports board-to-board or cable configurations, providing design flexibility.

0022288023 (Molex KK254 Series) This Molex variant is electrically and mechanically equivalent to 0022288021, with the primary distinction being gold contact finish on mating surfaces (15.0µin / 0.38µm) versus tin. Gold plating provides enhanced corrosion resistance and contact reliability in environments with higher humidity or corrosive exposure. Dimensional specifications match 0022288021. ROHS3 compliance and active product status are maintained.

0423771394 (Molex KK254 Series) This Molex option features extended contact lengths: mating contact 0.394" (10.00mm) and post contact 0.135" (3.43mm). These dimensions represent 0.076" (1.92mm) and 0.015" (0.38mm) increases respectively from the original part. Extended contact length accommodates thicker PCB assemblies or applications requiring deeper mating engagement. ROHS3 compliance and active product status apply. Verify PCB thickness compatibility before selection.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the 68423-402HLF?

A: All four substitute parts meet the core electrical and mechanical compatibility criteria: 2-position, 0.100" (2.54mm) pitch, through-hole right-angle header with solder termination and push-pull fastening. However, contact length variations must be evaluated against your specific PCB thickness and mating depth requirements. Parts 0022288021, 0022288023, and 0423771394 have slightly longer mating contacts than the original, which may affect fit in space-constrained applications.

Q: What is the difference between 0022288021 and 0022288023?

A: Both parts are mechanically and electrically identical Molex KK254 series headers with matching dimensions and specifications. The sole difference is contact finish: 0022288021 features tin plating on mating contacts, while 0022288023 features gold plating. Gold plating provides superior corrosion resistance and is preferred for applications exposed to moisture, salt spray, or corrosive environments. Tin plating is suitable for standard indoor and controlled environments.

Q: Why does 0423771394 have longer contact lengths?

A: The extended contact lengths in 0423771394 (0.394" mating / 0.135" post) are designed to accommodate thicker PCB assemblies or applications requiring deeper mating engagement. This variant is suitable when standard contact depths are insufficient for your board thickness or connector retention requirements. Verify that your mating connector or cable assembly can accommodate the extended contact length before selection.

Q: Are all substitute parts RoHS compliant?

A: The 77315-425-02LF is RoHS Compliant. The three Molex parts (0022288021, 0022288023, 0423771394) are ROHS3 Compliant. Both designations meet current RoHS requirements. The original 68423-402HLF does not specify RoHS status due to its obsolete classification.

Q: What is the current rating for these connectors?

A: Only 77315-425-02LF specifies a current rating of 3A per contact. The original part and the three Molex substitutes do not provide current rating specifications in their datasheets. For applications with specific current requirements, contact the manufacturer or consult detailed electrical specifications.

Q: Can I use these parts in automotive applications?

A: The Molex KK254 series parts (0022288021, 0022288023, 0423771394) list automotive applications in their specifications. The Amphenol ICC parts do not specify automotive applications. If your design requires automotive-grade qualification, verify compliance with relevant automotive standards (AEC-Q200, ISO 16750, etc.) with the manufacturer.

Q: What is the operating temperature range?

A: Only 77315-425-02LF specifies an operating temperature range of -65°C ~ 125°C. The original part and the three Molex substitutes do not provide operating temperature specifications. For applications with extreme temperature requirements, contact the manufacturer for detailed thermal specifications.
