Molex 0010897083 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0010897083 is a vertical rectangular connector header designed for through-hole mounting with 8 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This connector is part of the C-Grid 70280 series and is classified as active product status. The component features male pins with gold-plated mating contacts and tin-plated posts, suitable for board-to-board or cable applications in automotive, general purpose, lighting, medical, and telecommunications applications.

Substitute parts are necessary when the original Molex 0010897083 becomes unavailable, when design requirements demand alternative material specifications, or when compliance certifications differ from the original specification.

Engineering Selection Recommendations

Primary Substitutes (Active Product Status, ROHS3 Compliant):

TE Connectivity 5-146253-4 and 5-146252-4 from the AMPMODU Mod II series are direct functional equivalents with active product status and ROHS3 compliance. Both maintain the 0.100" (2.54mm) pitch, 8-position, 2-row configuration with gold-plated mating contacts. The 5-146253-4 features gold-plated posts while 5-146252-4 features tin-plated posts, matching the original Molex specification more closely. These parts support operating temperatures of -65°C to 105°C and 3A current rating per contact.

Secondary Substitutes (Active Product Status, RoHS Compliant):

Amphenol ICC (FCI) BERGSTIK series parts 77313-122-08LF, 77313-124-08LF, and 77313-127-08LF provide alternative solutions with active product status and RoHS compliance. These parts feature phosphor bronze contacts with gold or gold GXT finish on mating surfaces and tin-plated posts. Operating temperature range extends to -65°C to 130°C with 3A per contact current rating. Contact length variations accommodate different application requirements: 77313-122-08LF (0.305" mating length), 77313-124-08LF (0.266" mating length), and 77313-127-08LF (0.260" mating length).

Tertiary Substitutes (Active Product Status, RoHS Compliant):

3M 929 series headers (929665-01-04-EU, 929665-01-04-I, 929665-02-04-I, 929665-03-04-I) provide alternatives with active product status and RoHS compliance. These parts feature copper alloy contacts with gold plating on both mating and post surfaces. Operating temperature range is -40°C to 105°C with 2.5A current rating. Post length variations are available: 929665-01-04-EU and 929665-01-04-I (0.110" post length), 929665-02-04-I (0.210" post length), and 929665-03-04-I (0.410" post length) for different PCB stack-up requirements.

Legacy Consideration:

TE Connectivity 4-103322-0-04 is classified as obsolete product status with RoHS non-compliance. This part is suitable only for legacy applications where RoHS exemptions apply or where existing inventory must be maintained. The part features tin-lead plating on both mating and post surfaces with thermoplastic insulation material.

Frequently Asked Questions (FAQ)

Q: Can I substitute the Molex 0010897083 with any of the listed alternatives?

A: All listed substitute parts maintain the critical 0.100" (2.54mm) pitch, 8-position, 2-row configuration with male pin contacts, through-hole mounting, and solder termination. Mechanical and electrical compatibility is established for all active product status parts. Verify application-specific requirements including operating temperature range, current rating, and contact length before final selection.

Q: What is the difference between the TE Connectivity 5-146253-4 and 5-146252-4?

A: Both parts are functionally equivalent with identical pitch, position count, and row spacing. The primary difference is contact finish on the post: 5-146253-4 features gold-plated posts while 5-146252-4 features tin-plated posts. The 5-146252-4 more closely matches the original Molex specification with tin-plated posts. Contact finish thickness on mating surfaces also differs: 5-146253-4 has 30.0µin gold while 5-146252-4 has 15.0µin gold.

Q: Why do the Amphenol BERGSTIK parts have different contact lengths?

A: The three Amphenol BERGSTIK variants (77313-122-08LF, 77313-124-08LF, 77313-127-08LF) accommodate different PCB stack-up and mating depth requirements. The 77313-122-08LF provides the longest mating contact length (0.305"), while 77313-127-08LF provides the shortest (0.260"). Selection depends on the specific mechanical envelope and mating connector depth in your application.

Q: What is the difference between the 3M 929665 variants?

A: The 3M 929665 series differs primarily in post length to accommodate various PCB thicknesses and stacking heights. 929665-01-04-EU and 929665-01-04-I feature 0.110" post length (standard), 929665-02-04-I features 0.210" post length (extended), and 929665-03-04-I features 0.410" post length (long). Insulation material also varies: 929665-01-04-EU uses PCT while 929665-01-04-I, 929665-02-04-I, and 929665-03-04-I use PBT with glass fill.

Q: Should I use the obsolete TE Connectivity 4-103322-0-04?

A: The 4-103322-0-04 is classified as obsolete product status with RoHS non-compliance. Use this part only for legacy applications where existing inventory must be maintained or where RoHS exemptions apply. For new designs, select from active product status alternatives such as TE 5-146253-4, TE 5-146252-4, Amphenol BERGSTIK series, or 3M 929 series.

Q: What are the operating temperature differences between substitutes?

A: The original Molex 0010897083 does not specify operating temperature. TE Connectivity and 3M parts support -40°C to 105°C or -65°C to 105°C ranges. Amphenol BERGSTIK parts extend to -65°C to 130°C. Select based on your application's thermal requirements. Higher temperature capability does not affect compatibility if your application operates within the lower temperature range.

Q: Are all substitutes RoHS compliant?

A: All active product status substitutes are RoHS compliant (either ROHS3 or RoHS Compliant designation). The exception is TE Connectivity 4-103322-0-04, which is RoHS non-compliant and obsolete. For applications requiring RoHS compliance, avoid the 4-103322-0-04 part.

Q: What is the current rating difference between parts?

A: The original Molex 0010897083 does not specify current rating. TE Connectivity and Amphenol parts support 3A per contact. 3M 929 series parts support 2.5A per contact. Select based on your application's current requirements. If your application requires 3A per contact, avoid 3M 929 series parts.

Q: Can I mix different substitute parts in the same design?

A: All substitute parts maintain the same 0.100" (2.54mm) pitch and 8-position, 2-row configuration, allowing mechanical interchangeability. However, verify that contact length, post length, and electrical specifications match your specific application requirements before mixing parts from different manufacturers or series.
