Equivalent & Substitute Parts for Molex 0010892381

Part Overview

The Molex 0010892381 is a rectangular connector header designed for through-hole mounting with 38 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This connector is classified as obsolete, making substitute parts necessary for new designs and ongoing production requirements. The part features a breakaway design with unshrouded configuration, gold-plated mating contacts, and tin-plated posts suitable for board-to-board or cable applications across automotive, medical, telecommunications, and general-purpose applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0010892381 are qualified based on the following critical parameters that must match or be compatible with the original specification:

Mandatory Matching Parameters:

• Number of Positions: 38
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant or RoHS Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All four substitute parts meet these mandatory criteria. Variations in contact length, contact shape, contact material, insulation material, and contact finish thickness are within acceptable tolerances for rectangular connector substitution in this category.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are active products with current manufacturing support, addressing the obsolescence of the original Molex 0010892381. Selection among these alternatives depends on specific application requirements:

Preci-Dip 802-10-038-10-001101 offers gold-plated mating and post contacts with brass material, operating temperature range of -55°C to 125°C, and 3A current rating at 150VDC. This part provides enhanced contact durability through dual gold plating.

Preci-Dip 802-80-038-10-001101 provides tin-plated contacts with brass material, identical operating temperature and current specifications to the 802-10 variant. This option is suitable for applications where tin plating is acceptable and cost optimization is a consideration.

3M 961238-6404-AR features square contact geometry matching the original Molex design, with gold-plated mating contacts and copper alloy material. Operating temperature range is -25°C to 105°C with 2A current rating. This part maintains closest physical similarity to the original connector.

Samtec TSW-119-26-S-D provides phosphor bronze contacts with gold-plated mating surfaces, matching the original material specification. Operating temperature extends to -55°C to 125°C. This part offers the widest temperature range and maintains material consistency with the original design.

All substitute parts maintain ROHS3 compliance or equivalent RoHS compliance, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity level.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for the Molex 0010892381?

A: All four substitute parts share the critical electrical and mechanical parameters: 38 positions, 2 rows, 0.100" (2.54mm) pitch, through-hole mounting, solder termination, and push-pull fastening. Physical dimensions vary slightly in contact length and insulation height, which may require PCB layout verification for specific applications.

Q: What is the difference between the two Preci-Dip options (802-10 and 802-80)?

A: The primary difference is contact finish. The 802-10 features gold-plated posts, while the 802-80 features tin-plated posts. Both use brass contact material and provide identical electrical ratings (3A, 150VDC) and operating temperature range (-55°C to 125°C).

Q: Which substitute part most closely matches the original Molex connector?

A: The Samtec TSW-119-26-S-D maintains the closest material specification with phosphor bronze contacts and gold-plated mating surfaces, matching the original design. The 3M 961238-6404-AR also provides square contact geometry identical to the original.

Q: Are there temperature or current limitations I should consider?

A: The 3M 961238-6404-AR has a lower operating temperature maximum (105°C versus 125°C for other options) and lower current rating (2A versus 3A for Preci-Dip parts). Verify application requirements against these specifications.

Q: What packaging is available for these substitute parts?

A: All substitute parts are supplied in bulk packaging. Inventory availability ranges from 669 to 1025 pieces for active stock.

Q: Do all substitute parts meet the same compliance standards as the original?

A: All substitute parts maintain UL94 V-0 flammability rating, MSL 1 moisture sensitivity level, and ROHS3 compliance or equivalent RoHS compliance. REACH status is unaffected for all parts.
