Substitute Part Grouping Explanation

Substitution eligibility for the 68423-102HLF is determined by strict alignment with the following core parameters:

Connector pitch and position count: 0.100" (2.54mm) spacing with 2 positions in a single row
Mounting configuration: Through-hole, right-angle orientation for board-to-board connectivity
Contact type and termination: Male pin contacts with solder termination
Electrical performance: 3A current rating capability and UL94 V-0 flammability compliance
Environmental range: Operating temperature compatibility within -65°C to 130°C minimum

Engineering Selection Recommendations

Primary Substitute - Amphenol ICC 77315-125-02LF

The 77315-125-02LF is the closest functional equivalent to the obsolete 68423-102HLF. Both parts are manufactured by Amphenol ICC, share identical pitch, position count, and mounting configuration, and maintain equivalent contact geometry and electrical performance. The 77315-125-02LF is currently in active production status with 1079 units in stock. This part carries RoHS Compliant certification and REACH Affected status, meeting modern regulatory requirements. The operating temperature range of -65°C to 125°C covers the majority of applications within the original specification, with a 5°C reduction at the upper limit. This part is recommended as the primary replacement for new designs and ongoing production support.

Secondary Substitutes - Molex KK254 Series (0022288021, 0022288023, 0423771394)

The Molex KK254 series headers provide functional equivalence through matching pitch, position count, and mounting type. All three Molex variants are active products with ROHS3 Compliant and REACH Unaffected certifications. The 0022288021 and 0022288023 maintain identical contact post length (0.120") and insulation height (0.098") to the original part, with mating contact lengths of 0.324" (8.23mm). The 0423771394 features extended contact lengths (0.394" mating, 0.135" post) suitable for applications requiring deeper board penetration or thicker PCB assemblies.

Contact finish variations exist across the Molex options: 0022288021 features tin finish, 0022288023 provides gold finish, and 0423771394 uses tin finish. These finishes are electrically equivalent for standard applications. The Molex parts do not specify current rating or operating temperature range in the provided data, requiring verification against application requirements before selection.

Regulatory and Compliance Considerations

The 68423-102HLF carries no specified RoHS or REACH status. The 77315-125-02LF is RoHS Compliant and REACH Affected, while all Molex variants are ROHS3 Compliant and REACH Unaffected. For applications subject to RoHS or REACH restrictions, the Amphenol ICC 77315-125-02LF or Molex alternatives are appropriate selections. All substitute parts maintain UL94 V-0 flammability compliance and MSL 1 (Unlimited) moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can the 77315-125-02LF directly replace the 68423-102HLF in existing designs?

A: Yes. Both parts share identical pitch (0.100"), position count (2), row configuration (1), mounting type (through-hole right-angle), and contact type (male pin solder). The 77315-125-02LF maintains equivalent electrical performance at 3A per contact. The operating temperature range differs by 5°C at the upper limit (-65°C to 125°C versus -65°C to 130°C), which is acceptable for most applications. Verify your specific temperature requirements before implementation.

Q: What are the key differences between the Amphenol ICC and Molex substitute options?

A: The Amphenol ICC 77315-125-02LF is the closest match, sharing the same manufacturer and nearly identical mechanical dimensions. Molex KK254 series parts (0022288021, 0022288023, 0423771394) provide functional equivalence through matching core parameters but differ in contact finish options and extended contact lengths on the 0423771394 variant. Amphenol ICC 77315-125-02LF is recommended for direct replacement; Molex options are suitable when specific contact finish or extended contact length requirements apply.

Q: Does contact finish affect compatibility?

A: Contact finish does not affect mechanical or electrical compatibility for standard applications. The original 68423-102HLF specifies gold or gold GXT™ finish. The 77315-125-02LF maintains this specification. Molex alternatives offer tin (0022288021, 0423771394) or gold (0022288023) finishes. Selection should be based on application requirements for corrosion resistance or specific mating surface compatibility rather than substitution eligibility.

Q: Are there packaging differences between these parts?

A: Yes. The 68423-102HLF packaging is not specified. The 77315-125-02LF is supplied in Bag packaging. Molex parts (0022288021, 0022288023, 0423771394) are supplied in Bulk packaging. Packaging format does not affect electrical or mechanical performance and is a procurement consideration only.

Q: What is the significance of the "Breakaway" designation on substitute parts?

A: The Breakaway feature on the 77315-125-02LF and Molex variants indicates that individual positions can be separated from the header strip. This feature does not affect compatibility with the original application and provides additional flexibility for custom configurations. The original 68423-102HLF does not specify this feature, but its presence on substitutes does not preclude use as a direct replacement.

Q: Which substitute should I select for new production designs?

A: The Amphenol ICC 77315-125-02LF is the recommended choice for new designs. It is the active product from the original manufacturer, carries modern RoHS compliance certification, and maintains the closest dimensional and electrical equivalence to the obsolete 68423-102HLF. Molex KK254 series parts are acceptable alternatives if specific contact finish or extended contact length requirements apply to your application.

Q: Are all substitute parts RoHS compliant?

A: The 77315-125-02LF is RoHS Compliant. All three Molex variants (0022288021, 0022288023, 0423771394) are ROHS3 Compliant. The original 68423-102HLF does not specify RoHS status. For applications subject to RoHS restrictions, any of the listed substitutes are appropriate selections.
