Engineering Selection Recommendations

Primary Recommendation – Amphenol BERGSTIK® II Series (68020 and 68021 Base Numbers)

The Amphenol BERGSTIK® II series connectors (68020-138HLF, 68020-238HLF, 68020-438HLF, 68021-138HLF, 68021-238HLF, 68021-438HLF) are the preferred substitutes for the obsolete Molex 0010892386. These parts are currently active in production, RoHS Compliant, and maintain full electrical and mechanical compatibility. All variants support the required 38-position, 2-row configuration at 0.100" pitch with through-hole right-angle mounting and push-pull fastening.

Selection by Contact Finish:

For applications requiring gold-plated mating contacts, select from 68020-138HLF, 68020-238HLF, 68021-138HLF, or 68021-238HLF. The difference between these variants lies in contact finish thickness (30.0µin or 15.0µin) and post contact length (0.095" or 0.120"). For tin-plated mating contacts, select 68020-438HLF, 68021-438HLF, or 68697-438HLF.

Selection by Current Rating:

Standard applications requiring 3A per contact are satisfied by the 68020 and 68021 series. For higher current applications requiring 5A per contact, select Amphenol 68697-438HLF, which features tin-plated mating and post contacts with 0.125" post length.

Selection by Voltage Rating:

The 68021 series (68021-138HLF, 68021-238HLF, 68021-438HLF) includes a 110V voltage rating specification. The 68020 series does not specify voltage rating. For applications with explicit voltage requirements, the 68021 series is appropriate.

Secondary Recommendation – Amphenol BERGSTIK® Series (77317 Base Number)

The Amphenol BERGSTIK® series (77317-104-38LF and 77317-403-38LF) provides alternative substitutes with extended operating temperature range (-65°C to 130°C) and thermoplastic insulation material. These parts are active in production and RoHS Compliant. The 77317-104-38LF features gold-plated mating contacts with tin-plated posts; the 77317-403-38LF features tin-plated mating and post contacts.

Not Recommended – TE Connectivity 4-103149-0-19

Although the TE Connectivity AMPMODU Mod II connector (4-103149-0-19) matches the core electrical and mechanical specifications, this part is discontinued at DiGi Electronics and carries RoHS non-compliant status. This part should not be selected for new designs or ongoing production requiring RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can I substitute any of these parts directly into an assembly designed for the Molex 0010892386?

A: Yes. All listed Amphenol BERGSTIK® and BERGSTIK® II substitutes maintain identical pitch (0.100"), position count (38), row configuration (2 rows), mounting type (through-hole right-angle), and fastening mechanism (push-pull). Physical and electrical compatibility is confirmed across all recommended substitutes.

Q: What is the difference between the 68020 and 68021 series?

A: The primary difference is voltage rating specification. The 68021 series includes a 110V voltage rating; the 68020 series does not specify voltage rating. Both series support identical position count, pitch, mounting type, and current rating (3A per contact). Select based on application voltage requirements.

Q: Does contact finish thickness affect compatibility?

A: Contact finish thickness does not affect mechanical or electrical compatibility. Variations in gold plating thickness (30.0µin vs. 15.0µin) or tin plating thickness (78.7µin vs. 100.0µin) are acceptable for equivalent functionality. Selection should be based on application corrosion resistance and environmental requirements.

Q: What is the difference between gold-plated and tin-plated contact finishes?

A: Both finishes are acceptable substitutes. Gold-plated contacts (68020-138HLF, 68020-238HLF, 68021-138HLF, 68021-238HLF, 77317-104-38LF) provide superior corrosion resistance and are preferred for high-reliability applications. Tin-plated contacts (68020-438HLF, 68021-438HLF, 68697-438HLF, 77317-403-38LF) are cost-effective alternatives suitable for standard industrial applications.

Q: Can I use the 68697-438HLF if my application requires higher current capacity?

A: Yes. The Amphenol 68697-438HLF is rated for 5A per contact, compared to 3A per contact for the standard 68020 and 68021 series. This part is suitable for applications requiring higher current capacity while maintaining all other electrical and mechanical specifications.

Q: What is the operating temperature range for the original Molex part?

A: The Molex 0010892386 does not specify an operating temperature range in the provided data. Substitute parts offer specified ranges: TE Connectivity 4-103149-0-19 (-65°C to 105°C), Amphenol BERGSTIK® II series (-65°C to 125°C), and Amphenol BERGSTIK® series (-65°C to 130°C). Select based on application temperature requirements.

Q: Are all recommended substitutes RoHS Compliant?

A: All Amphenol BERGSTIK® and BERGSTIK® II substitutes are RoHS Compliant. The TE Connectivity 4-103149-0-19 is RoHS non-compliant and should not be used for applications requiring RoHS compliance. The original Molex 0010892386 is ROHS3 Compliant.

Q: What is the difference between post contact lengths (0.095", 0.110", 0.120", 0.125")?

A: Post contact length determines solder joint depth on the PCB. Longer posts (0.120", 0.125") provide greater solder joint engagement; shorter posts (0.095") reduce solder volume. All variants are mechanically compatible. Selection should be based on PCB thickness and solder joint design requirements.

Q: Can I mix different substitute part numbers in the same assembly?

A: All recommended substitutes maintain identical electrical and mechanical specifications for the 38-position, 2-row configuration. Mixing different part numbers is acceptable from a compatibility standpoint. However, for manufacturing consistency and traceability, using a single part number across an assembly is recommended.

Q: What does "Breakaway" connector type mean?

A: Breakaway connectors feature individual pin rows that can be separated or broken apart after assembly. This allows for flexible configuration of the connector. The Molex 0010892386 and most Amphenol substitutes support this feature, enabling customization of pin count if required.

Q: Is the TE Connectivity 4-103149-0-19 a viable substitute despite being discontinued?

A: The TE Connectivity part is electrically and mechanically compatible but is discontinued at DiGi Electronics and RoHS non-compliant. For new designs or production requiring RoHS compliance, Amphenol BERGSTIK® or BERGSTIK® II series are recommended. The TE Connectivity part may be considered only for legacy system maintenance where RoHS compliance is not required and inventory is available.
