Key Parameters

Substitute Part Grouping Explanation

Substitute components for the Molex 0010892561 are identified based on strict electrical and mechanical compatibility criteria. The following parameters define acceptable substitution:

Critical Matching Parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 56
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Shape: Square
• Contact Material: Phosphor Bronze
• Material Flammability Rating: UL94 V-0

Allowable Variations:

• Contact Length - Mating: Variation permitted within mechanical envelope constraints
• Contact Length - Post: Variation permitted based on PCB thickness requirements
• Insulation Material: Alternative materials acceptable if maintaining UL94 V-0 rating
• Contact Finish Thickness: Variation permitted within functional specifications
• Operating Temperature: Extended range acceptable for active components
• Current Rating: Higher ratings acceptable for enhanced performance

The Samtec Inc. MTLW series connectors meet all critical matching parameters while offering active product status and enhanced specifications.

Parameter Comparison

Engineering Selection Recommendations

Both Samtec MTLW series connectors provide active product status with full ROHS3 compliance and UL94 V-0 flammability certification, addressing the obsolescence of the Molex 0010892561.

MTLW-128-05-G-D-230 Selection Criteria: This variant features reduced overall contact length (0.335" vs. 0.437") and shorter post length (0.045" vs. 0.107"), suitable for applications requiring compact vertical profile. The gold-plated post finish provides enhanced corrosion resistance compared to tin plating. Thinner mating contact finish (10.0µin) is acceptable for standard signal applications.

MTLW-128-07-S-D-270 Selection Criteria: This variant maintains overall contact length (0.430" vs. 0.437") and post length (0.100" vs. 0.107") closer to the original specification, with tin-plated posts matching the Molex contact finish configuration. Mating contact finish thickness (30.0µin) matches the original specification exactly. This variant provides mechanical compatibility with existing PCB designs requiring minimal rework.

Both substitutes provide specified operating temperature range (-55°C ~ 125°C) and current rating (5.2A per Contact), exceeding the unspecified ratings of the obsolete component. Liquid Crystal Polymer insulation material in both Samtec variants offers superior thermal and mechanical properties compared to polyester glass-filled insulation.

Frequently Asked Questions (FAQ)

Q: What are the critical compatibility requirements for substituting the Molex 0010892561?

A: The substitute connector must maintain 0.100" (2.54mm) pitch, 56 positions in 2 rows with 0.100" row spacing, male pin contacts, through-hole solder termination, push-pull fastening, square contact shape, phosphor bronze contact material, and UL94 V-0 flammability rating. All Samtec MTLW series variants meet these requirements.

Q: How do contact length variations affect PCB design compatibility?

A: Contact length variations determine the vertical envelope and mating depth. The MTLW-128-07-S-D-270 maintains contact dimensions closest to the original specification (0.430" overall vs. 0.437"), minimizing PCB rework. The MTLW-128-05-G-D-230 requires reduced mating depth accommodation due to shorter overall length (0.335").

Q: Are the Samtec substitutes suitable for automotive and medical applications?

A: Both Samtec MTLW variants provide ROHS3 compliance, UL94 V-0 certification, and MSL 1 (Unlimited) moisture sensitivity rating, meeting regulatory requirements for automotive and medical applications. Operating temperature range (-55°C ~ 125°C) supports these application categories.

Q: What is the difference between tin and gold post finishes?

A: Tin-plated posts (MTLW-128-07-S-D-270) match the original Molex specification and provide cost-effective solderability. Gold-plated posts (MTLW-128-05-G-D-230) offer enhanced corrosion resistance and are preferred for high-reliability applications with extended storage or harsh environmental exposure.

Q: Can both Samtec variants be used interchangeably in the same design?

A: No. The variants differ in contact length, post length, and overall height. Design selection must be based on specific PCB thickness requirements and vertical space constraints. MTLW-128-07-S-D-270 provides closer mechanical compatibility with designs originally specified for the Molex 0010892561.
