Equivalent & Substitute Parts for Molex 0010892441

Part Overview

The Molex 0010892441 is a rectangular connector header designed for through-hole mounting with 44 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This connector is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production support. The part features male pins with gold-plated mating contacts and tin-plated posts, suitable for board-to-board or cable applications across automotive, medical, telecommunications, and general-purpose industries.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0010892441 is determined by strict alignment of the following critical parameters:

Core Compatibility Parameters:

• Number of Positions: 44
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Material: Phosphor Bronze
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All three substitute parts meet these core compatibility requirements. Variations in contact length, insulation height, contact finish thickness, and insulation material do not prevent functional substitution when the mating pitch, position count, and electrical termination method remain constant.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with ROHS3 compliance and MSL 1 rating, providing long-term availability and environmental regulatory alignment superior to the obsolete Molex 0010892441.

Samtec MTLW-122-07-S-D-250: This part offers the closest overall contact length (0.430" vs. 0.437") and maintains tin post finish matching the original. The Flex Stack MTLW series uses Liquid Crystal Polymer insulation, which provides enhanced dimensional stability compared to polyester glass-filled material. Operating temperature range of -55°C to 125°C and 5.2A per contact rating are specified.

Samtec MTLW-122-23-G-D-245: This variant provides gold-plated posts in addition to gold-plated mating contacts, offering enhanced corrosion resistance. Contact length mating dimension (0.245") is closest to the original (0.240"). The longer post length (0.140") accommodates thicker PCB assemblies. Identical operating temperature and current rating specifications apply.

Samtec TSW-122-26-L-D: This part features the TSW series with Polybutylene Terephthalate insulation and maintains tin post finish. Insulation height (0.100") matches the original specification exactly. Operating temperature range of -55°C to 125°C is specified.

Selection among these three substitutes depends on specific application requirements regarding contact finish durability, insulation material properties, and PCB thickness accommodation. All three maintain functional compatibility with the original 44-position, 2.54mm pitch header specification.

Frequently Asked Questions (FAQ)

Q: Can the Samtec MTLW-122-07-S-D-250 directly replace the Molex 0010892441 in existing designs?

A: Yes. Both parts share identical mating pitch (0.100"), position count (44), row configuration (2 rows), contact type (male pin), mounting method (through hole), and termination (solder). Variations in contact length and insulation material do not prevent functional substitution when PCB layout and connector cavity dimensions accommodate the specified tolerances.

Q: What is the significance of the different insulation materials used in the substitute parts?

A: The Molex 0010892441 uses polyester glass-filled material, while the Samtec MTLW series uses Liquid Crystal Polymer (LCP) and the TSW series uses Polybutylene Terephthalate (PBT). All three materials meet UL94 V-0 flammability requirements. LCP and PBT offer improved dimensional stability and moisture resistance compared to polyester, which may benefit applications requiring tighter tolerances or exposure to humidity.

Q: Are there differences in contact finish that affect substitution?

A: The original part features gold-plated mating contacts with tin-plated posts. The MTLW-122-07-S-D-250 and TSW-122-26-L-D maintain this configuration. The MTLW-122-23-G-D-245 uses gold plating on both mating contacts and posts, providing enhanced corrosion resistance at the cost of increased material expense. Selection depends on environmental exposure and reliability requirements.

Q: How do contact length variations affect compatibility?

A: Contact length variations (ranging from 0.230" to 0.250" mating length) reflect different connector stack heights and PCB thickness accommodations. These variations do not affect electrical compatibility when the mating pitch and position count remain constant. PCB layout and connector cavity design must accommodate the specific contact length of the selected substitute.

Q: What is the inventory status of these substitute parts?

A: The Molex 0010892441 is obsolete with 1005 units in stock. All three Samtec substitutes are active products with current inventory: MTLW-122-07-S-D-250 (1062 units), MTLW-122-23-G-D-245 (870 units), and TSW-122-26-L-D (791 units). Active product status ensures ongoing availability for production and future orders.

Q: Do all substitute parts meet the same regulatory and compliance standards?

A: Yes. All three substitute parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications with the original part. Compliance alignment simplifies procurement and regulatory documentation.
